Talk:Audion

message: I see that LightCurrent REALLY wants to merge this in with Vacuum tube..
In favor of this I can see that the audiotron WAS in some ways the first triode, (and probaly the first thyratron but thats another story)
One actually could also move the information to the pages of the inventors..
Against, this is a "more detailed" deeper pass that can be looked up for more inforamation.
I think that it can be filled out MORE, particularly the story about the hard vs soft vacuum issue.  By thinking that the audion needed a soft vacuum, it probaly delayed the real vacuum tube by several years.
A sidelight is McChandless (I probaly have his name misspelt) who made many audions under licence, and probaly did much of the early development.
The other thing that I see as Missing is the whole patent situation, this was one of the patents that prevented ANYONE from legaly building a radio commeraly in the US.  It was only after RCA and Western electric agreed to split the market, with RCA having radio, and western having Toll wire communications, and pooling the patents both held/controled that making a radio was posible.  This also held up radio for another five years.
Thoughts on where this could go?

replies: text: It seems to me from what's said above that just from a historical point of view, the Audion is unique and notable enough to merit its own article.  And if it is to be merged, I think the appropriate article to merge it into would be Triode, not Vacuum tube.  --ChetvornoTALK 13:36, 7 December 2009 (UTC)

It appears whomever wrote that forgot about the existance of LCD and plasma display-based sets. — Preceding unsigned comment added by 97.115.33.102 (talk) 02:15, 8 July 2012 (UTC)

message: This historical session at the Audio Engineering Society convention was very informative. Adams should be used as a source.

Licensed ham radio enthusiast and San Francisco lawyer Bartholomew "Bart" Lee (K6VK, xKV6LEE) wrote the Foreword to the Adams book. Lee says the "Audion" name came from "audible ions". Whether that is true or not I think it would be helpful for this article to draw from new source material. Binksternet (talk) 20:15, 6 January 2013 (UTC)

message: The lede section of the article has undergone a rewrite with the inclusion of many much needed references (no complaints there!).  Unfortunately, the lede is no longer a lede as such but an article section in its own right.  Also the lede now contains all but one of the article's references.
The lede is supposed to be a summary of the main content of the article.  As such, it should not contain any references at all because these should all be in the main article.  At present, the lede contains much information that is not mentioned elsewhere.  It therefore fails as a summary.  The new information needs to be moved to an appropriate section of the article along with its references, and the lede reduced until it is a summary of the article content.

replies: text: The lede doesn't have to contain citations but it can, there's nothing wrong with it (WP:LEADCITE).  The lede contains most of the citations because the existing article was so poorly cited.  We can add citations to the article, but there is no reason to remove them from the lede.  Similarly, most of the points from the lede are discussed in the article, and the few that aren't can be added.    Each of the points in the lede is a notable part of the audion story, and at minimum the article should cover them.  If it doesn't it is because it is so unevenly written.  I'd be glad to add them.  I thought you wanted to improve the article? --ChetvornoTALK 18:25, 9 January 2013 (UTC)
replies: text: Some writers compose an opening statement before writing the main article text. I think that the encyclopedia article, following Wikipedia's house style guideline at WP:LEAD pretty much recommends first writing the article body, then going back and summarizing the body in the lead section. Expanding the lead section first is not wrong, specifically, and it should not be reverted, but a strong effort should be made to improve the article body such that the lead section is a summary of the body. Along the way, I expect that emphasis on this or that point in the article body may indicate some changes to the lead section, to reflect the emphasis. Binksternet (talk) 19:04, 9 January 2013 (UTC)
replies: text: The previous lede was very incomplete and had a few blatantly wrong statements, so I felt there was an urgent need to rewrite it.  While I was at it I thought I might as well make it a good summary of the topic.  The article does at least mention most of the points in the lede, but I'll work on improving it.  --ChetvornoTALK 19:35, 9 January 2013 (UTC)

::"However, the operation of the audion is in many ways quite different from that of the pure electron device operation in the way I have described above."
::"In the audion, as well as in the Lieben-Reisz relay, the amplifying action appears to be largely dependent on gas ionization, even when the device operates well below the point at which the blue glow appears.  The action is probably somewhat as follows: there is normally present a small amount of gas ionization, due to the passage of the electrons between cathode and anode.  The presentce of the positive ions partly neutralizes the space charge which limits the current flowing between cathode and anode.  The presence of the positive ions partly neutralizes the space charge which limits the current flowing between the electrodes.  If a small positive potential is applied to the grid the velocity of the electrons passing by it is somewhat increased and they therefore produce more ions in the gas.   Besides this, as the potential on the grid is increased, the number of electrons passing the grid is increased, and this again tends to increase the amount of ionization.  A very slight increase in the amount of ionization brought about in this way very greatly reduces the space charge and therefore largely increases the current that can flow between the electrodes.  Thus, with a given construction of grid, filament, and plate, the relaying action may be very greatly increased beyond that which would occur if no gas was present."

* DeForest Radio Co. v. General Electric Co., 283 U.S. 664 (May 25, 1931). "Of critical importance in the present controversy is the effect of the presence of gas within the tube."  "In consequence, the low vacuum tube is more sensitive both as a detector and as an amplifier than a tube of high vacuum." "August 20, 1912, the earliest date claimed for Langmuir, was rejected rightly, we think, by the District Court, which held that Langmuir was anticipated by Arnold in November, 1912. But before the earlier date, De Forest sought and obtained a high vacuum in the audions used as amplifiers, and observed that when the vacuum was too low the blue glow effect occurred at from 15 to 20 volts. In order to secure higher voltages from the audions used as amplifiers and to procure the requisite high vacuum, he had some of the bulbs re-exhausted while superheated. By August 1912, the Telegraph Company used De Forest amplifying audions at 54 volts, and by November, they were used by another at 67 1/2 volts. This was possible only because the tubes had thus been exhausted of gas, which would otherwise have ionized with blue glow at from 20 to 30 volts."

thread_title:  Possible references 

message: I'm not sure what it is with some people, but this is another fairly brief Wikipedia article which is completely dwarfed by the size of its talk page :-). As with so many other important technological developments whose potential was vastly underestimated at the time, in the light of the unprecedented research facility afforded by the Internet, the accepted "history" has been exposed as "mostly bunk", based on uneducated guesswork, and "house-of-mirrors" pieces by lazy journalists.
Until recently Google News used to have an "Archives" section, where you could look at newspapers dating back the the 19th century. A lot of them were "Pay-per-view", but there were quite a few free ones as well, and in the 1920s most newspapers had "Wireless" sections of one sort or another. It is sometimes quite staggering the difference between "accepted" reality, and reports written at the time.
I found the real story of Kenotrons and Pliotrons in a 1919 newspaper, and I was intending to link to it on this page, but unfortunately, Google no longer supports that function.
This article is also starting to suffer from "Wiki-rot" where endless rounds of pointless editing have completely erased the original meaning of some sentences. Not replaced them with something different but still valid, but replaced them with gibberish in some cases.
