ULISES ARMAND SANABRIA


Mr. Manuel A. Martinez, who lives in Puerto Rico, contacted me in early November 2003, to offer access to his research into the life of Ulises Armand Sanabria.

In 1989 he wrote and published a Spanish language book titled:  "Chicago: Historia de Nuestra Comunidad Puertorriqueña"  ---   [Translation:   "The History of Puerto Ricans in Chicago"].  Ulises A. Sanabria's father and grandfather were Puerto Rican.

In 1966, three years before his death in 1969, the 60-year old U. A. Sanabria wrote a brief autobiography about his life's accomplishments. 

Mr. Martinez has been gracious to allow that document, and other rare photographs to be published here.

The development of my helium carbon dioxide arc for the television receiver started with low pressure light columns, using a hot cathode and a shielded anode with the shield having a copper tunnel in which the discharge took place.

After many trials we learned to conserve all of the discharge and work in a range of pressures which made the covering of the anode or the cathode with a sheath unnecessary.  A voltage drop of 65 volts across the cathode and anode went lower with a rise in current measuring 2-1/2 ohms negative resistance.  This made it possible to terminate a twisted pair of wires so that the positive resistance of the wire matched the negative resistance of the lamp.  Low loss at high frequency by the use of matching lamps and resistance made it possible to transmit over several miles of a twisted pair of wires with as good results as at the output of the transmitter.  We were, therefore, enabled to design a 10 channel mechanical system using only 15 lenses in a small disc which resolved a 10 spot lamp on a translucent screen.  This gave a total of 150 lines which had a resolution of 300 lines of present day television.

The system was ideal for wired television.  We only needed a disc, a synchronous motor and a lamp in the home. A 12 wire cable was used and no amplifying tubes were necessary in the home.  The synchronous motor was used to drive a recording hour meter so that the number of hours of television could be paid for like any other utility service. This system was very enchanting and was quite ready for commercialization in 1934.  It permitted the projection of 30' square pictures.

During tests, the screens were used out-of-doors and made of sand blasted celluloid reinforced by vertical piano wires.  The screen acted like a sail on a boat, so it had to be used with care.

During the year 1931, the stock of the Sanabria Television Corporation was qualified for trading on the New York Produce Exchange.  During that time I learned about practices in merchandising of stock, became thoroughly acquainted with tipster sheets, trading specialists, rigging the market, sucker lists, and so much more that I forced the Attorney General of New York to remove the stock from the market and never again indulged in a public stock corporation.

By 1932, I had received a grant of the interlaced scanning patent, but had many patent applications pending on mechanical and cathode ray methods.  I was invited by a Dr. William I. Sirovich, chairman of the Patents Committee, of the House of Representatives, to head up a patenting pool committee of many financial leaders, whereby my work was to be declared by the President of The United States as worthy of a special patent examiner who would go over the head of the Commissioner Of Patents in order to expedite action.  At that time there was a two year interference law, rather than one year, which permitted much trading with an inventor before his patent was issued.  A "rubber stamp" system of patent issuing had been devised which would have made it possible for the committee under my direction to rig a patent situation to dominate the industry.

I had much difficulty in withdrawing from participation in that situation because the desire to use our public stock position, combined with the ability to rig patents, appealed to the mature and corrupt interests as an "offering from Heaven".  It had one flaw, however, and that was that the Sirovich committee was counting on me to steal from other inventors and they failed to appreciate that I was a genuine inventor and could not be made to purloin the work of other pioneers in television.  However, I moved in very high level circles in politics and finance for a few months and became thoroughly disillusioned with the patent system.  In fact, I got to looking at it as a section of our government which was as badly slanted as a ticket fixing ring in traffic court.  The penalty for withdrawing was to abandon my patent applications.

There had been developed a hardy crew of television scientific men, each one of whom is successful in the pre­sent industry.  We decided that we would disperse to various laboratories and give up the hope of commercial success through patents.  Two went to RCA, one to Philco and four of us to the formation of American Television Institute, a school for the preparation of future television manpower so that the industry which had to be born at some suitable scale, would have the men available to do the work when the time came.

Through our knowledge of the malpractice in patents, we were able to insure that there was no patent control of television transmission, a vital thing at one time for freedom of telecasting.  Our testimony during 1940 and our work on the National Television Systems Committee panels resulted in the division of the NBC, and to the breaking up of NBC into ABC and NBC.  We insured that only a few stations could belong to any one network. By 1941 we had complete facility, camera links and 2,000 men ready for telecasting employment.  At this point we ran into an absurd trouble with the Federal Trade Commission, who desired us to cease and desist from alleging that there was a future in television.  We vigorously fought this for eight years, covering the difference between 'what made a technician and an engineer', the source of authority for a degree granting institution, and uncovered the fact that in our United States we had no acceptable definition for an engineer and no uniformity of college practice.   By 1948 the Federal Trade Commission became so embarrassed with the suit that they dismissed it entirely and dismissed the lawyer who started it from employment with the Federal Trade Commission.

Retracing our steps to the World War Two years, American Television, of which I was the principal stockholder and president, had a national correspondence school; a four year residence school in Chicago, Detroit and Los Angeles, and we were setting up one in New York on Pearl Harbor Day.   2,000 of our students were recruited by the armed services in different parts of the country.  We mobilized our best instructors and equipment from all of our schools and concentrated our effort in Chicago. The Signal Corps tested the students of the Chicago division of RCA Institutes and our own school and selected ours for the first contract for radar training.  Management of RCA was so vexed with the showing of RCA Institutes, which had formerly been the Marconi Institutes, that they closed their Chicago school and never returned.

Our school gradually became the largest private school in the country, having a continual enrollment of 6,000 men in a four year training, in which we granted the first Bachelor Of Science degrees in television.  The men are in all corners of the industry.  Those of you who read this will find graduates of American Television employed by your own company.

At this time, 1947, the whole question of profit versus non-profit in the field of education began to rear its head.   The fact that we were able to buy and remodel large buildings into first class school facilities, pay taxes and make a sizeable margin out of tuitions, which the non-profit colleges were claiming were in adequate was becoming an embarrassing subject to conventional higher educators who were not required to pay taxes of any kind, nor to buy any new equipment, nor to prepare new curriculums.

I took the position that if the profit motive, under our American system, could be depended upon for the best automobiles, appliances and products, it could also be depended upon to produce the best graduates in the field of new technology.  I contended, in session before the Veteran's Administration, that the role of the profit school in pioneering industry is to induce scientific leaders, by payment of sufficient money, to leave industry in favor of the financial opportunity in profit schools.  A divided camp resulted.  I insisted that a profit school be entitled to collect as much tuition as a non-tax paying institution and billed the government accordingly.

The Veteran's Administration, however, was insisting that we could not use the college method of billing by the semester but rather by the days of attendance only.  Since I insisted on the semester billing, the Veteran's Administration retaliated by having a Grand Jury vote a True Bill against me for overcharging the government.  This True Bill was never reduced to an indictment because I learned about it and appealed to the Attorney General to send the FBI, to investigate and hold the indictment until the investigation was complete.  The FBI investigation cleared me and the indictment was never returned.

Stepping back into the War Years again, the Signal Corps appealed to us to try and make cathode ray tubes which we were doing in a very small way before the War.  We were rated as having a capacity of 50 per day but stepped this up to 1,000 per day of all sizes.  The attempted indictment by the Veteran's Administration formed the excuse necessary for an ambitious segment of my enterprise to form the National Video Corporation.

The appeal to leave and work for National Video was based on the fact that American Television was going to be destroyed and "poor old boss, Sanabria" would need a job which his faithful followers would have ready for him. Since these people who formed National Video had all worked for me for more than fifteen years and gone through much of the grand experience of television pioneering,  I had come to expect complete loyalty from a group which had identified itself as American Television.  They were earning salaries of from $20,000 to $60,000 annually and I was thoroughly depressed by their exodus.

The Westinghouse Company gave American Television a $1,000,000 letter-of-intent to purchase cathode ray tubes and the Tung-Sol Company was to get one-half of our production and Westinghouse the other half.

The manufacture of picture tubes held for American Television a completely new glass technique because it involved what is commonly called "soft glass" as opposed to "hard glass" which we had used for radar and cathode ray tubes during World War Two.  We had become adept at handling all of the high temperature glasses produced by the Corning Glass Works where the working temperatures produced incandescence.  The substitution of thermocouple pyrometers at low temperature and Dumet wire seals was a backward step because the higher bake-out temperature of the hard glass previously resulted in a better vacuum.

We started to produce 10" round picture tubes in December, 1948 and by May, 1949 we were manufacturing 500 per day.  Tube sizes increased very rapidly and by December, 1949 we were making our first rectangular 16" tubes.   In the meantime, our school flourished and we started the production of our first television sets.

During the year 1950 our profits climbed to $2,000,000 annually, so I started three new projects.  The first was a centrifugal casting company; the second was a transpondence course in which the student received a tape recorder and a film projector and corresponded by talking to the instructor (the instrument was called a transponder).  High speed re-recording was used for what we believed to be the first time in such an enterprise.  The third was to re-enter military research and development and manufacture image storage tubes, hydrogen thyratrons and test gear for same.

Everything expanded all at once and no provision had been made for proper banking procedures, so that all the enterprises became co-mingled financially.  This resulted in prohibitive taxes and military refunds, so that in our most successful years, through 1955, we ended with overburdening liabilities to the Excise Tax Division of the Internal Revenue Service and the Fiscal Divisions of the Armed Services, as a result of converting the basis of the Excise Tax to the retail, rather than the factory price.

We had substantial outlets for our television sets in our self-owned stores in Chicago, Detroit, Cleveland, Evansville, St. Louis, Tulsa, Oklahoma City, Washington and Los Angeles.  We also had independent dealers in Grand Rapids, Philadelphia, South Bend, Toledo, Wichita, Houston, Jacksonville, Milwaukee, and many other place I cannot quickly recall.  We exported to Canada.  Our rate of production was 1,000 sets weekly.

During this period I was extensively involved in the daily preparation of retail advertising.  Our budget for newspaper advertising was generally $30,000 weekly and it had to be continually new and different.  The design of the furniture or cabinets was also largely personal and I continually reviewed and approved the electronic performance and the picture tube quality.

We took much pride in the fact that we trained the manpower, built the cabinets, the picture tube and the entire television chassis - more of the whole set than most of our competitors.  We wrote and printed our own textbooks for the school, doing our own illustrating and photography, and trained personnel for every profession in television, including the acting.  During these years I was also active in inventing.

Going back to 1926, I believed that light could directly affect electrons in motion, but soon realized that I was observing the photo-electric effect.  My staff and I developed long column gas discharge lamps using both cold and hot cathodes and many types of alkali metal cells.  I became familiar with glass blowing tools, materials and techniques.  Optical systems, illuminating sources and flicker photometry became daily practice.  The use of lenses and mirrors and precision mechanical devices of all types was a necessity which led to the world's finest amplifiers for that time, covering from 0 to 100 kilocycles with minimal phase distortion.  Constant exploration of the human eye system for a clue to make television easier was never-ending.  I developed methods and means for producing, color television, light amplifiers, tape recorders and reproducers, transmitter for sound and television, stereophonic systems and three dimensional television systems.  I conducted lecture classes in these foregoing subjects.

I had interesting periods of side hobbies and engineering diversions such as, microscopic observation of the growth of bacteria, a backbone thermometer for recording the temperature junction where nerves enter the spinal column, the effect of thyroid extract on the common cold, use of diathermy for many medical benefits, use of a reversing mirror to aid prospective actors and the novel use of cues by authors of television productions to speed rehearsals, home heating plants combining electrical generation so as to more fully utilize fuel, vacuum glass caskets for the dehydrating of bodies for extended preservation, power yachting, the composition of music with a few numbers widely accepted.

I escorted the captured submarine U505, with my yacht "Airbanas", from Montreal to Chicago, which is now at the Museum of Science and Industry.

Some other hobbies are the design of self-taxpaying money and money systems, the creation of a consumer's stock exchange, the utilization of ceiling merchandising rights in super-grocery stores, the uniform replacement and utilization of television sets so that they can be traded annually and maintained at different economy levels, the invention and promotion of lineless television with veils of critical mesh, soil less charcoal, electrolytic lipstick.

Among recent inventions not reduced to patent, are a light image amplifier, a picture on the wall type of large screen television not using a cathode ray tube and a compatible system of transmitting and receiving two pro­grams simultaneously on each television station while not interfering with present day television receivers, method of quadrupling the television information on video and audio tape.                                            

I am well acquainted with Federal Trade rules and procedures, general business custom and capable of developing and promoting most advances in the fields of electronics and optics. I prefer those projects which are a combination of profit and socially efficient end use.
