Edgar Cayce Readings, 1497-7

(Material mind and body, his associations and activities. You will again have before you the subject matter, which I hold in my hand, submitted on June 22, 1938, in the matter of a radio tube for the suppression of static. Reference is made to the answers to questions given through this channel on the date mentioned. You will answer the following questions, as I ask them, to clarify certain points which are not understood sufficiently so that the body may proceed with the construction of the experimental tube along definitely proscribed lines:)

TEXT

EC: Yes, we have the body, the enquiring mind, [1497]; this we have had before; together with the information which has been indicated regarding a static eliminator, or suppression of static with the use of the tube in radio receiving set.
Ready for questions.
(Q) Referring to 1497-6, Par. 5-A: Are the radio antenna (aerial) AND the first tube of the radio set referred to as "the high tension wire and tube" in this answer? If not, to what does this expression refer?
(A) To the antenna and the first tube.
Hence this comes between the high tension or the first tube and the set itself, or the amplifier.
(Q) Can static charges on the antenna be identified as "high tension" in this case, or does "high tension" relate to the so-called plate voltage?
(A) To this first receiving tube, you see, from the antenna; that is called the high tension receiving.
(Q) Referring to 1497-6, Par. 7-A: Is mica itself suitable "non-conducting" material with which to inter-connect the discs in series?
(A) Rather the mica would be the discs themselves, and such as bakelite the inter-convening between the discs.
(Q) Will these discs shed or by-pass charges of static so that same will be automatically separated from the broadcast signal, - or stated differently, - will ONLY the static charges be absorbed by the surfaces of the discs and thence by-passed to ground?
(A) These are eliminating static and are thus by-passed to the ground. Hence the series - the edges, see - are grounded.
(Q) Is the static charge when so conducted, that is, - coming down through the aerial and tube, of a positive or negative nature?
(A) Of a negative nature; that is, negative to the reception, see?
(Q) Is it proper to connect only the lowest disc on the filament, by means of a metal connection, to ground?
(A) The edge of each disc would be connected and thus the bottom to the ground.
(Q) Is it NECESSARY to connect the discs in succession by means of non-conducting material in view of their being commonly mounted on the filament sheath?
(A) It is necessary, as has been indicated, to separate these and make thus a laminated series, see?
(Q) Is the series connection between the discs better than a multiple or parallel connection?
(A) Multiple.
(Q) Referring to 1497-6, Par. 9-A: Should the mica discs be composed of a SET of two or three laminated layers, - that is to say, does the word "set" refer to a GROUP of two or three layers of mica for each disc?
(A) Three layers for each set - or for each disc.
(Q) Referring to 1497-6, Par. 10-A: Should there be more than ONE filament in the static suppressor tube itself, - each having three discs?
(A) There only would be the three, and thus they each would have their set, see?
(Q) If two filaments with discs are necessary in ONE tube for each radio set, is the rectifier principle, disclosed in the subject matter at hand, correct?
(A) This is correct - the outline that has been indicated is correct.
(Q) Is it advisable for the tube itself to be of the glass enclosed type or metal enclosed?
(A) For the ordinary receiving set, the glass. However, for the larger set, or the more POWERFUL set - as might be used in interchangeable broadcasts (which might come later) - it would be of metal.
(Q) Should the metal enclosure be grounded also?
(A) Use the glass, as has been indicated, in the experimentations. Later the metal, when for the larger or more powerful or interchangeable sets.
(Q) Then should that be grounded also?
(A) Not necessarily - the glass.
(Q) To further clarify 1497-6, 10-A, will you confirm or change my paraphrasing of this answer as follows: - "six would be correct, if three discs are placed on each of two filaments, the six discs EACH being composed of a set of three laminated layers of mica, - namely, six sets of laminated layers, three layers in each set."
(A) This is correct.
(Q) Referring to 1497-6, Par. 11-A: Does the word TUBE refer to the filament sheath or "tube" surrounding the filament heater, or should more than ONE static suppressor tube be employed in each radio set?
(A) Only one tube - static tube - for each radio set, but these are enclosed, see?
(Q) Please clarify this answer by stating whether two or three discs are necessary on each filament.
(A) As has been indicated, the three.
(Q) Should the laminated layers in each disc be loosely touching, pressed together securely, or fastened together with metal eyelets which may be used to also attach the series interconnection between discs?
(A) These as we find, rather as indicated - the sets, or the laminations of the three pieces or layers of the mica are separated by a non-conductor and the edges of the mica are then set as for the manner or means of grounding same.
(Q) Referring to 1497-6, Par. 13-A: An error was made by the body in designating the "cathode." Please advise if the cylindrical ANODE, shown as a cathode in the subject matter, should surround the discs entirely or partially?
(A) Partially.
(Q) Should the cylindrical anode, as contrasted with the filament cathode, be clear of the edges of the discs, or should it touch same?
(A) Be clear of same.
(Q) If two filaments are necessary, will ONE common anode, in the form of a flat plate, located between the two filaments and their discs, be correct?
(A) This will be correct.
(Q) Will the results obtained by an experimental tube, built as indicated, demonstrate what further steps and improvements are necessary?
(A) As has been indicated, this will demonstrate and it will show - as indicated - that the necessary experimentation is in the distances between the sets of the laminated mica necessary on the filament.
(Q) Will this channel be available for future advice in this connection?
(A) If these will be followed, this may be available.
(Q) Can good patent coverage be obtained on this suggested structure?
(A) This may be obtained.
(Q) How should this channel be recognized in connection with such patent?
(A) Only as those so patenting same see fit!
(Q) Will the Sylvania Tube Company or the Hygrade-Sylvania Corporation at Emporium, Pennsylvania be the best place to have this tube build?
(A) The Sylvania Corporation as we find would be the better.
(Q) Any further advice?
(A) Follow these and as we find, with a little experimentation, we will find a tube that will be as revolutionary to the reception of the radio receiving set as was the first tube for the amplification of same.
We are through for the present.

REPORTS

7/28/38 [1497]'s letter to EC:
Dear Mr. Cayce:-
The reading was very clear and got rid of all ambiguity and confusion. I believe I grasp every point of the answers to my questions. Of course, in a thing like this, there are many, many more questions which could be asked - but I believe some obligation accrues to me to exercise my judgement as to certain details.
One answer only tended to be vague - but that was cleared up by a later question. I have already taken steps to have a model constructed and believe it may take a month or six weeks to get the tube and try it out.
Will of course let you know of progress. Two points I should like to emphasize with which I feel you will strongly agree. The first is that the project should be kept confidential - and, until results are established by practice, - no attempt will be made to patent it. There is such a deeply ingrained conviction in the radio profession that static can NOT be eliminated - that it is likely the patent office could refuse a case, unless it is undisputably reduced to practice. I have full faith it will be - and will then make application. This operation may take a year to fulfill.
I am determined that, should there be any financial returns in connection with it, the world shall be blessed by its being so. I also assure you that the Association will be recognized in such an event - so that your work may be helped and benefitted.
The second part is that should a patent on such a technical subject be granted through such definite psychic aid as has been evident here, there might be an occasion, since its subject matter would affect a vested industry, to bring out publicity of too materialistic a character.
It is my obligation to use this in doing good and for HIS glory and the thing to do is to await definite results and we will then go back to the sources for guidance and act properly to safeguard the position attained, so that the device may not be pre-empted by selfish interests who would be only too glad at the opportunity to attack its patent validity.
I therefore urge caution in keeping the matter quiet until the vine is ripened. There is surely a miracle here and it will be made to bless all who have had a part in it.
It is our duty to make no conscious mistakes and I cannot help, in this case, to recall the admonition - "And He charged them that they should tell no man". The wisest course is always silence - letting Truth be its own herald.
One thing I would like to let you know about. My first conception of the device was incorrect in several ways and incomplete with respect to modern practice. Even after receipt of the last reading - an important technical part was missing - but a little prayer did the trick and a solution came to me which takes care of it in a very novel and advantageous method. You see, I had to hook this tube up with a feasible way to TUNE the radio set to different stations and the first sketch didn't show that. Every point is now definitely planned.
Please give my warm regards to your good assistants and with many blessings to you. Faithfully yours, [1497]

10/03/38 [1497]'s letter to EC:
New York Murray Hill ...
Dear Mr. Cayce:-
I have had a time trying to convince the Hygrade Sylvania people that there was something in the static eliminator tube.
They finally have consented to make a few samples, but want $200.00 for the job. My faith is still steadfast - but in the process of reviewing details they required certain changes in the design of the tube which may not come within the correct interpretation of what was given to us in the previous readings.
Questions of tube performance are involved as to heating, mounting details and the relative position of the different elements which I had to adapt to their needs to get them to consent to build the samples at all.
The attached list of questions are very carefully prepared. The answers will either solve the problem or indicate that my understanding of what is being conveyed, is greatly at fault. Previous readings have not indicated thus, and in spite of technical advice, with one exception - a man who is a very eminent radio engineer - I believe that the matter will be clarified so that, at the reasonable risk with which the last reading left me, - I can proceed with my experiments.
I am compiling a second list of questions about my affairs for a later reading and would be pleased to hear from you setting an appointment for this one. With warm regards to all, I am Sincerely yours, [1497]
P.S. Will you please return the charts A to D - as they are the only identification I have with the questions.
