Encounter With the Washing Machine Wringer

Even after all these years of association with the space program I am still amazed at the progress of technology during my life time, especially the progression from tube type electronics to micro-circuitry that has made such great changes in our ability to communicate and handle data.  I have observed that every new technology development comes with fears that it may be misused or present some sort of hazard to the populous.  


My first encounter with new technology and it danger came when our family acquired a wringer washing machine about the time I was just starting to walk.  The washing machine precipitated an incident that physically scared me for life.  That incident is in my memory only because of its repeated telling by my mother and grandmother.  Apparently, the trauma of the event completely erased it from my conscious memory. 

   

Every Monday Mama Weaver would come over to our house to help Mother with the wash.  In our washroom was a wringer washing machine and two #3 galvanized wash tubs sitting on a bench beside it.  When the clothes had been sufficiently sloshed about and agitated in the machine, they would be taken out  of the washer and put thru the wringer and dropped into a tub of clean water for  the first rinse; then the wringer head would be swung around to the other tub and the clothes would be put thru the wringer into the  other tub for the second rinse.  Lastly, the clothes would be put thru the wringer one last time and into a basket for carrying outside where they would be hung on the clothes lines to dry.  


Occasionally, as the garments were fed into the wringer, one of them would fail to drop into the tub and continue around one of the wringer rollers.  It only took a couple of extra turns for the thickness to build up and cause the safety mechanism to pop the two rollers apart and stop the wringing action.  After some tugging and prying the tangled garment would be removed, the mechanism reengaged and the wringing of clothes resumed.


One wash day I played and watched as the ladies did the wash.  My sister, Nancy, was helping by guiding the clothes into the rinse tubs.  However, no one was watching the little boy when he reached up to examine the pretty pink rubber rollers.  My screams and the “clunk” of the rollers popping apart quickly got their attention.  My left arm was stuck between the rollers up to the elbow as I hung suspended five inches off the floor.  For a moment everyone else joined me in screaming.  As Mother held me, somehow Mama Weaver  managed to extract my now red and swollen arm from the wringer.


Wash day came to a halt as the priority became to get me to the doctor for they were sure that my arm was crushed.  They wrapped my arm in one of the freshly washed towels from the basket and since Mama Weaver did not drive she held me in her arms as we sped the nine miles to the doctor’s office in Tuscaloosa.  My cries soon subsided to an occasional sob or whimper but Nancy cried most of the way about her little brother’s broken arm.


After an examination, the doctor assured them that my arm was not crushed but it was badly bruised and I had a deep wound on the underside  of my forearm where all the the layers of skin had been scraped away by the turning action of the rubber roller.  The healing process took a long time and many bandage changes and left me with a permanent scar about half the width of my arm.

JOHN and RUTH


My former pastor, John, was a passionate man.  He was passionate about preaching the gospel of Christ.  He was passionate about playing the piano.  And, oh yes, he was passionately in love with Ruth.  

As a young man, John preached the gospel in tent-meetings across the South with the Rev. Glenn V. Tingley.  One of the churches which had its roots in those tent meetings was the Alliance Church in Gadsden, Alabama.  John went to Toccoa Falls Bible College in the mountains of north Georgia to study to be a christian minister.


Ruth was an instructor in Bible History and Greek.  By her own admission, she was an old maid school teacher and intended to serve the Lord in the capacity of training preachers and missionaries for the rest of her life.  John took some of Ruth’s classes and was quite taken with her.  On the close-knit campus, their paths crossed almost daily.  Perhaps, John even began to plan chance meetings.  Ruth was several years his senior so he knew that it was unlikely that a real romance could develop between them.  The rules of the college forbid fraternization between staff and student, so their relationship remained that of student and teacher and of good friends.  Still, for John, there was an attraction that he could not lay aside all through college.  


After the graduation ceremony, John found Ruth in the crowd to have one last conversation with his friend.  When he told her that he was headed to pastor a new church plant in Gadsden, Alabama, she asked him to promise to come back to the campus in a year and tell her about his first year of ministry and how the work in Gadsden was doing.


John plunged into his task for a year and the Gadsden church grew as souls were added to the family of God.  John was consumed in his ministry but as the days went by, he became more and more convinced that Ruth was the woman that God had chosen for him.  He determined that he would pursue a more serious relationship with her.  As a successful pastor, he could offer her a house and home and an opportunity to serve the Lord in a growing work.  


He was convinced that this was the right thing to do, but still, there was a lingering doubt.  What if she rejected him.  With much prayer, he set out for Toccoa.  If his plea fell on deaf ears, he was ready to take that as a sign from God and to go on without her to the work that God had laid before him. 


He arrived on campus on the last day of regular classes.  He went directly to Ruth’s class which was about to begin.  He entered the room with the students and quietly slipped into a seat at the back of the room.  A few students noticed this intrusion but Ruth seemed not to notice her extra student.  She proceeded with a final lesson and then a concise review of the semester's work.  John sat there content to be back in her presence but soon found himself listening intently as if he had to take the exam.  She concluded the review, reminded the class of the scheduled time for the exam and dismissed them with a prayer.  


Over the next week, as Ruth administered and graded exams, they managed to renew their friendship.  By the end of the week, a proposal had been made and accepted and a wedding date set.


John and Ruth went north to be married in her home church in Pennsylvania.  They were driven there by an older minister and his wife in their Ford A-Model Roadster.  If you remember, the Roadster had only a front seat in the cab and an open-air Rumble Seat which was where the trunk is on modern autos.   When the weather was clear, Ruth and John sat in the Rumble Seat.  When it rained, all four of them crowded into the cab on the front seat.  Now, that seat is not wide enough for four so when it rained, Ruth sat on John’s lap.  In later years, John would reminisce, with a chuckle, of that time of closeness as symbolic of their closeness through their years.




He and Ruth raised four children and he preached the gospel as the pastor of several other churches.  He preached the gospel on a missionary trip to India.  He preached the gospel as pastor of an International Church in Cambodia.  He preached the gospel as a traveling evangelist.


From the evangelist road, he and Ruth came with their travel trailer to pastor our church and stayed on to shepherd us for several years until failing health led him to resign.  After a time of recover, he began to accept an occasional evangelistic engagement.  He went back to his first pastorate, the Gadsden church, for a series of meeting and while there he fell sick and went to be with the Lord.

A SOLID STATE DEMULTIPLEXER for the SATURN





This is an account of just one of the many times where NASA helped  push our electronic world out of the old technology and into the transistor/solid-state electronic era.  I have wanted to tell this story for some time, but have just recently taken the time to write it down.


The development of the SATURN system of launch vehicles proceeded from the Saturn 1 - Block 1 to the Saturn 1 - Block 2, and then to Saturn 1B -Block 1, and Saturn 1B - Block 2, and then on to the Saturn 5.  We began to expand and upgrade our ground test equipment as new technology and schedule considerations presented the opportunities. In our telemetry ground stations, we discarded the oscillograph recorders, whose long scrolls of data had to go through a photographic development and drying process, and installed recorders that used thermal sensitive paper that came out of the machines fully developed.   


We had performed the Redstone and Jupiter telemetry testing with ground stations whose electronics were almost entirely based on vacuum tube technology.  During Mercury/Redstone testing we acquired some equipment that used the new transistor technology in special circuits.  The flight equipment of the Saturn rocket would make more use of transistor circuits.  


Our first real leap into the world of transistors was when we added a new set of signal discriminators in preparation for Saturn tests.  Many of our engineers and technicians had little knowledge or experience with transistor circuits.  Luckily, we had Tom Flanders on our contractor support staff.  Tom had taught transistor circuits at Georgia Tech while getting his masters degree in electronics.  He left the academic world and hired on with our NASA contractor, Chrysler Corporation.  We got approval, through the MSFC training department, for him to teach Transistor Circuits to all those in the laboratory who desired such training.  That worked out well for NASA and for those who took the training.


The Saturn 1st stage data system had flight multiplexes that placed the output of 300 sensors into a data stream and sent it to a ground station where a demultiplexer would separate the 300 signals.  Our existing demultiplexer could process the 300 signal data stream, but it suffered from over heating and vacuum tube failures.  Also, during operation it required constant adjustments.  We were in dire need of a replacement before we began the Saturn 1B and Saturn V tests.  We had talked with several vendors in the telemetry market about the possibility of a demultiplexer based on transistor technology but none of them offered such an unit . One vendor did offer to supply a transistor based demultiplexer on a cost-plus development contract.  


Tom Flanders had been working with the technician who was responsible for the demultiplexer in an effort to solve some of its problems.   He told me that rather than waste his time on the old machine I should let him just build a new machine.  He assured me that he could do that with transistor logic boards and other components currently available on the market.  I asked him and my lead telemetry technician, Prince Jones, to explore his idea further and if it still seemed feasible, to bring me a proposal which we could take to our Advanced Projects office for possible funding.  


When they had the proposal ready, we presented it to Paul Davis, the Laboratory lead for Advanced Projects.  This was the same Paul Davis that I had worked for in the Measurement Test Section during my first Coop session.  He gave us approval to proceed and made funds available for the equipment and parts we needed.


I assigned another contractor engineer, Earl Benson, to work with them.  The designation for the effort and eventually the final Design became “BFJ” after the thee men working on the project.  Along the way some doubters begin to say BFJ stood for “Big Fat Joke”. However, in a few weeks, they produced a breadboard version that met the basic requirements.  Along the way, Earl Benson left the project and Charles Mandy took his place, but the BFJ name stuck.


Several more weeks to work out the component layout and design the control panel and, we had a working unit that fit neatly in three drawers of a standard equipment rack and needed only moderate cooling.   Whereas, the old model occupied 3 standard racks and required massive cooling.  We worked with the designers of the flight multiplexer in a series of verification tests to prove we had a design that could reliably process the output of the flight multiplexer.


We then contracted with Brown Engineering to build units for our Systems Test telemetry ground station.  We also made copies of the design documentation available to other NASA groups and to any vendor that may want to supply similar units for the program.

 Lost in the Woods :


         My former pastor, John, was a passionate man.  He was passionate about preaching the gospel of Christ.  He was passionate about playing the piano.  And, oh yes, he was passionately in love with Ruth.   
----------------------
Preaching The Gospel
As a young man, John preached the gospel in tent-meetings across the South with the Rev. Glenn V. Tingley.  One of the churches which had its roots in those tent meetings was the Alliance Church in Gadsden, Alabama.  After finishing Bible school, John became pastor of that church.  

Down through the years, he and Ruth raised four children and preached the gospel as the pastor of several other churches.  He preached the gospel on a missionary trip to India.  He preached the gospel as pastor of an International Church in Cambodia.  He preached the gospel as a traveling evangelist.

From the evangelist road, he and Ruth came with their travel trailer to pastor our church and stayed on to shepherd us for several years until failing health led him to resign.  After a time of recover, he began to accept an occasional evangelistic engagement.  He went back to his first pastorate, the Gadsden church, for a series of meeting and while there he fell sick and went to be with the Lord.  

John was one of the few men that I have known that throughout his daily life carried on a running conversation with God.  I do not mean that he stopped what he was doing, bowed his head and addressed God in a formal way.  He would just blurt out something like, “Father, that sure is a beautiful sunset you have for me today.”  Or, if faced with a decision, he might say, “Father, help me decide which way to go.”  Because of this trait, in my mind, I compared him to that great friend of God, Abraham, and to Tevye from the Broadway play, Fiddler On The Roof. 

Playing The Piano
    John loved music.  John really loved gospel music.  John really, really loved gospel music on the piano.  John really, really, really loved playing gospel music on the piano.  When John arrived at our church he immediately assumed the duties not only of the pastor but as pianist for special music and for congregational singing.  John played with a flair and much enthusiasm.  His style was great for piano specials but not too comfortable for congregational singing and when accompanying singers, he tended to overpower them.

Apparently, he was unaware that our longtime pianist was one of the best, if not the best in Huntsville, Alabama.  Whether congregational singing, piano solos, or accompaniment of singers, her style was always appropriate and beautiful.  After a few weeks of sideways glances and whispered comments, a delegation visited John and tried to tactfully advise him of the situation because we were afraid that our pianist would find somewhere else to serve.  John understood and gracefully began restricting his playing to occasional specials which were appreciated and enjoyed by all.

Ruth
Ruth was an instructor at Toccoa Falls Bible College in the mountains of north Georgia.  By her own admission, she was an old maid school teacher and intended to serve the Lord in the capacity of training preachers and missionaries for the rest of her life.  John took some of Ruth’s classes and was quite taken with her.  On the close-knit campus, their paths crossed almost daily.  Perhaps, John even began to plan chance meetings.  Ruth was several years his senior so he knew that it was unlikely that a real romance could develop between them.  The rules of the college did forbid such fraternization between staff and student, so their relationship remained that of student and teacher and of good friends.  Still, for John, there was an attraction that he could not lay aside all through college.  

After the graduation ceremony, John found Ruth in the crowd to have one last conversation with his friend.  When he told her that he was headed to pastor a new church plant in Gadsden, Alabama, she asked him to promise to come back to the campus in a year and tell her about his first year of ministry and how the work in Gadsden was doing.

John plunged into his task for a year and the Gadsden church grew as souls were added to the family of God.  John was consumed in his ministry but as the days went by, he became more and more convinced that Ruth was the woman that God had chosen for him.  He determined that he would pursue a more serious relationship with her.  As a successful pastor, he could offer her a house and home and an opportunity to serve the Lord in a growing work.  

He was convinced that this was the right thing to do, but still, there was a lingering doubt.  What if she rejected him.  With much prayer, he set out for Toccoa.  If his plea fell on deaf ears, he was ready to take that as a sign from God and to go on without her to the work that God had laid before him. 

He arrived on campus on the last day of regular classes.  He went directly to Ruth’s class which was about to begin.  He entered the room with the students and quietly slipped into a seat at the back of the room.  A few students noticed this intrusion but Ruth seemed not to notice her extra student.  She proceeded with a final lesson and then a concise review of the semester's work.  John sat there content to be back in her presence but soon found himself listening intently as if he had to take the exam.

She concluded the review, reminded the class of the scheduled time for the exam and dismissed them with a prayer.  John remained in his seat as the others exited the room.  Ruth sat at her desk intently looking over some papers on her desk and seemingly oblivious to her admirer.  John moved up and took a seat directly in front of her desk and patiently waited for her to finish.  After a while, he cleared his throat just to make sure that she knew that he was there.  She looked up, smiled at him and went back to her task.  Finally, she gathered her papers into a stack and looked up again.  He started to speak but the words would not come out. 
She smiled again and said, “Yes, John.”  
Taking her words as permission to speak, he found his tongue, 
“Miss Gaff..er, Ruth, I have a question for you.”
“John, I said, yes.’’ 
“But, I haven’t asked the question yet.”
“Yes, John, I will marry you.”
When the exams were over and graded, John and Ruth went north to be married in her home church.  They were driven there by an older minister and his wife in their Ford A-Model Roadster.  If you remember, the Roadster had only a front seat in the cab and an open-air Rumble Seat which was where the trunk is on modern autos.   When the weather was clear, Ruth and John sat in the Rumble Seat.  When it rained, all four of them crowded into the cab on the front seat.  Now, that seat is not wide enough for four so when it rained, Ruth sat on John’s lap.  In later years, John would reminisce, with a chuckle, of that time of closeness as symbolic of their closeness through the years.
----------------------
John never wavered in the afore-described passions, preaching the gospel, playing the piano, and loving Ruth.  He did, however, develop other passions which he would throw himself into and enjoy for a season and then abandon.  Before he came to us he had been an ardent scuba diver.  For a while he was a rock hound, digging and polishing rocks and making jewelry and belt buckles for his friends.  He studied and worked each of these until he mastered them and then lay them and the associated equipment aside.

THE HUNTING TRIP  
Some men in the church were hunters.  They took John deer hunting and he was hooked.  He hunted with one or more of them every chance he got.  Once, he and one of his hunting buddies had planned a hunt but the friend had to cancel at the last minute.  Contrary to good hunting rules, John decided to go alone.  

As the sun was coming up he arrived at the place on the edge of the National Forest where the group had taken him the week before.  He followed an old logging road back about two miles.  About half way in, he had to drive through a small stream.  Fording the steam was not a problem as long as there had been no recent rain.  It was a clear day and rain was not predicted so he was not worried about his ability to cross the stream on his return.

His intention had been to hunt through the morning, eat his lunch, hunt some more and leave in mid-afternoon.  After lunch, he found a place in the sun and sheltered from the breeze where he could look over a large open area of tops from harvested trees.  He had seen three deer earlier.  Two does came close to him but the buck traveling with them never got close enough for a good shot.  Maybe if he sat very still a large buck would wander within range.
When he awoke the sun was going down.  He hurried to his car.  He was sure he knew the way back but was somewhat apprehensive about finding his way back to the highway if it got dark.  As he drove along the trail it was defiantly getting darker.  

He approached the stream confident that crossing it would be no problem even in the fading light.  Perhaps he hurried a little too much.  He entered the steam with a great splash and the engine died.  Try as he might, he could not get it restarted.  He decided that if he was to get out of the woods and back to the highway for help he had better get started while there was still some light.  He stepped out of the car and into very cold water just deep enough to fill his boots.  Well, he would just have to walk with wet feet.  The temperature was dropping and he knew he would have to get help soon or be in real trouble.  

Following the old logging road in the daylight had been no problem but as it grew darker the trail began to look more and more like the rest of the forest floor.  Soon he was not sure whether he was on the trail or not.  He paused for a moment to listen for some sound that might indicate how close he was to the highway.  He thought he heard a movement behind him.  He turned to see a large head and shoulders silhouetted against the now starry sky.  He thought to himself, “I didn’t know that there were bears in this forest.”

Suddenly the bear was shining a flashlight in his eyes and saying, “Is that your car parked in the middle of the creek back there?  Man, we better get you to some place warm before you freeze to death.  Follow me.”  He sat off at a rapid pace through the woods trailing the flashlight beam some what behind him so John could find his footing.  Even though he was cold and shivering, John would have liked to go slower but he was not about to let this man out of his sight.  

Shortly, John could see a light up ahead. He kept following the man and soon they were at the door of a small log cabin.   The interior of the cabin was quite rustic but neat.  The man went straight to the fireplace and added a couple of logs while instructing John to pull up a chair in front of the fire and get out of his wet boots.  For the first time, John got a good look at his host.  He was large, well over six feet and perhaps 250 pounds.  He had a full beard and a long pony tail pulled through the back of a BAMA ball cap.  He wore a camouflage parka and military style boots.  He told John to make himself comfortable while he went for help. Without another word, he was out the door.

John finished taking off his boots, got out of his coat and propped his cold feet up by the fire.  He leaned back in the chair and enjoyed the warmth emanating from the fireplace.  He noticed a large porcelain coffee pot setting on the hearth.  Lifting the lid, he determined by the smell that it, indeed, contained coffee, very strong coffee.  He rummaged around for a cup and poured himself some.  

While being warmed by the fire from without and by the coffee from within, John sat there remembering the events since he awoke in the woods.  As was his habit when in a contemplative mood, he was conversing with his Heavenly Father about the wonder of it all and thanking him for the help sent his way.  

An hour or more must have passed for when John checked his socks,  which were hung over the back of a chair in front of the fire, the were dry.  His shoes were also considerably dryer.  Soon the door swung open and his host entered.  “Get your boots and coat on.  Your cars out of the creek.  I’m gonna take you to it.”

Once again they were moving fast through the woods.  The man must be able to see in the dark for he had handed John the flashlight as they left the cabin.  After about twenty minutes of up and down hills and crossing small streams they emerged onto the highway in sight of a Quick-Stop gasoline station.  There sat John’s car, none the worst for its ordeal.  

For a moment John was left speechless, then he turned and handed the flashlight back to his benefactor.  He extended his hand and said, “My name is John.”  As his giant hand firmly gripped John's, his only reply was, “I’m Pat.”  John began thanking Pat for his help and was trying to ask what he owed him for his trouble.  “Man, you don’t owe me nothing, just have a safe trip home.”   With those words, he gave John’s hand one last squeeze, turned and disappeared into the woods

John got into the car and was about to drive off when he thought that he should call and let Ruth know that he was safe and would be home before long.  He went into the station to make the call.  While there he asked the young attendant about Pat.  The attendant said that all he knew was that Pat lived over in the woods somewhere and came around sometimes, usually when he was helping someone.  As John drove home that night, he had much to talk over with his Heavenly Father.

In 1993, Alabama managed to entice the 

Mercedes Company of Germany to build its 

new automobile plant near the little town of 

Vance just east of Tuscaloosa.  Upon reading 

the news, a few verses about rednecks in 

Mercedes began to form in my head. I must 

admit that I borrowed the format and the first 

few lines from Janis Joplin.


Alabama-Benz

 

 

 

Oh Lord, won’t you buy me a Mercedes-Benz,

For such fancy wheels, I’d give up my sins.

Worked hard all my life, have nothing but friends,

Oh Lord, won’t you buy me a Mercedes-Benz.


Can you believe a Mercedes pick-up truck.

Colored red, it could sure change my luck.

I will take it hunting and shoot a big buck.

Can you believe a Mercedes pick-up truck.


Oh Lord, keep me on the right track.

Let it be delivered with a golden gun rack.

I’ll drive down the road with my dog in the back.

Oh Lord, keep me on the right track.


Dressed in my overalls and Caterpillar cap,

I’ll cruise the town with a girl on my lap, 

Or park under a tree and take a short nap.

Dressed in my overalls and Caterpillar cap.

         COOKIE PLEASE

I rise from my place of rest.
I am on a secret quest.
I check to see where you are,
Then head for the cookie jar.

I lift it down from the shelf,
Almost ashamed of myself.
Conscience saying, I should stop
As I quietly lift the top.

Plunging hand ready to grip, 
Oatmeal, ginger, chocolate chip.
A fleeting panic arises,
As empty space surprises.

As my fingers touch the prize,
You step in and say “Surprise!”
Then sweetly, “Cookie please!”
Who could resist such a tease.

As I see you standing there, 
Have no choice, but to share.
I extend the jar with a pout,
You reach in and take one out.

One bite brings delight to you,
Oh! sweet sound of crunch and chew.
My mouth waters, my pallet aches
As my stomach anticipates.

I move to relieve the pain,
The prize at last I will gain.
With shaking hand now I grope,
Clutching air and losing hope.

Stand I now with fallen face,
Staring at an empty space.
I could have sworn there were two,
One for me and one for you.
