It turns out that the Burroughs B7971 and the Ultronic Systems Lectrascan were not the first 14-segment electronic stock ticker display system. In an interesting coincidence, the system that pre-dated it was designed by a man named Burroughs (no relation to the company of the same name). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Hi, yeah, I really should add a manufacturer category.

Right now I have to move because I recently switched universities and that is eating up quite some time too. But I can promise that I have a full box of Nixie tubes (that is, at least 20 or more), very interesting types.

[neonixie-l] Re: Nixie tube history: The role of Ericsson
* * *So it appears that the Haydu Bros made the components (little metal fiddly bits) that went into a vacuum tube. They also then did the same for Burroughs, for such things as the individual metal numerals. Burroughs saw the value in it, and probably decided to do it in-house, but the easy way. Just buy the supplier. Maybe, this was a trend in the 50's (?). If so, the Haydu's other customers also went in-house, but by building their own facilities (?). That would've made Haydu an attractive buy, for Burroughs.* * * *Then Burroughs developed the nixie, all on their own. Maybe, with a little insight, from the likes of National Union.* * * * * -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] Re: Nixie tube history: The role of Ericsson
Hi Jens, I posted the patent here on the forum this August, https://groups.google.com/forum/?fromgroups#!topic/neonixie-l/e3jIeheCiCQ , along with the three- and two-headed dekatron patent - I'd love to see one such dekatron running! You have been able to search for almost all patents for a few years time now, at least all that have been scanned and catalogued, at the EPO Espacenet website here: http://www.epo.org/searching/free/espacenet.html - I dug up a few of the Dekatron related patents this summer and posted them here on the forum I was actually looking for other patents related to AVO Valve Testers but found these Dekatron patents along the way. I also found a huge number of display related patents covering Nixies and also earlier technologies as well, so have a go at searching yourself. Just beware that you can spend whole days trying to track down what you are looking for and you sometimes also end up reading a lot of other interresting patents as you get distracted by other nice items! It is quite interresting to search for patents, not only for the items that you are looking for but more so to look where the inventors have been employed as that shows which companies got information from which other companies via the inventors. Digging through old literature will also give you a lot of information on what patents to search for, the hardest thing to solve is when the patent numbers have been either misprinted or mixed up with other patents.

[neonixie-l] Re: Nixie tube history: The role of Ericsson
Forgot to add another comment I had after reading the patent... The tube appears to use a similar approach to the National Union tubes, where any individual electrode could be used as an anode or a cathode, depending on what glowing shape the user wanted to display. It's been stated before that difficulty in driving the NU tubes using the circuitry of the day might have contributed to their design being superseded by the simpler to use Burroughs nixie. And indeed perhaps something similar played here - looking through all my collection of Ericsson materials, I can find no evidence they ever sold this tube - the first ETL nixies seem to be the GR2G, GR4G, GR10G etc of the mid-late 1950s, which are more conventional in operation / design.

[neonixie-l] Re: Nixie Tube History - help needed
Hmm sorry I was a bit slow on responses. I am a little confused about all these codes, basically I have never heard of these before, and I have no clue where to search for them. As I understand it, these codes were used to indicate in which equipment the respective component (here: our Inditron) was used, to enable quick references in the future. So what this code could be used for is finding out in which equipment the Inditron was actually used. This equipment is most likely some some aircraft control thingy, right? Anybody made progress in finding something more detailed? I have been digging into Burroughs history a little deeper, and found out that they mention their indicator tube program in their 1958 Annual Report. 1958, that is right. Three years late, that is weird, since they started adertising the Nixie tube since 1955 as a huge breakthrough, so why not mention it in their annual report? Also interesting within the 1954 Annual Report - Haydu Brothers of Plainfield NJ listed as a Burroughs Manufacturing Plant. (so far not confusing). In the report, there is the following text about the Haydu plant: Similarly, in acquiring sources of supply for electronic and other components of business equipment, other products have been acquired (!). Thus, Burroughs is moving into growing fields outside that of office equipment. Haydu Brothers, for example, acquired in 1954, manufactures cathode ray television tubes and other precision components for the electronics industry. Other products have been acquired! This is the first time that I have read evidence for Burroughs acquiring products from Haydu Brothers. Any comments? Jens On 20 Nov., 01:28, A.J.

[neonixie-l] Re: Nixie Tube History - help needed
In all likelihood, the GI-10 does not have an anode because they had not yet managed to invent an anode configuration which did not infringe on the Boswau patent or the Northrop patent or any of the other early gas discharge patents. The Burroughs Nixie is the earliest known production tube with a dedicated anode electrode, and the anode design does not infringe on the Boswau patent, which describes a device with a dedicated anode for each digit. That Inditron advertisement serves as evidence of one important point - it proves that the Inditron was in development while Saul Kuchinsky was employed by National Union. Various patent dates strongly suggest that he was employed by NU during the right time period, but if National Union had somehow managed to develop the Inditron in only a few months prior to the 1954 release, Kuchinsky would have already left to work at Burroughs. The ad specifies a development time measured in years, which means Kuchinsky was definitely employed there during the development period.

Re: [neonixie-l] Re: Nixie Tube History - help needed
I'm not even going to entertain the possibility of Telefunken Nixies in the 1940s. You might as well tell me the Germans developed a functional atomic bomb in the 1930s but never patented it or used it because they didn't want to infringe on US atomic bomb patents that would later be filed in the 1940s. I am just curious what makes him believe that. His Haydu/Burroughs story contains true elements but they are somewhat mixed up, but the TFK story seems completely wrong. That is why I am confused a little. I am sure, though, that if TFK had made early Nixie tubes, our Jan Wüsten would have knowledge about it. [...] The earliest Burroughs Nixie patent dates to 1956 IIRC, and there are no Haydu Nixie patents. It is not entirely impossible that somebody will eventually turn up a pre-release 6700 from 1954, but I'm confident the Haydu/Burroughs Nixie did not exist in a manufacturable state until 1955. Yes, based on our collected material this is the only reasonable conclusion. I still have to find that early Burroughs patent though. There was a time when I knew some numbers, but this is half a year ago (I somehow lost track of the patent research I have to admit, it is such a detailed work...) A note on Haydu's role: Although the beam switching tube and Nixie were electrically designed by Burroughs, I think it's a foregone conclusion that Haydu production engineers were heavily involved in the high-volume refinement of these tubes. If you note the Stems Sockets brochure, they're making a big fuss about the high-pin-count button bases they're using. I'm guessing the button bases are a direct result of Haydu production engineering. That is interesting. I think Burroughs meant to understate this issue, citation of E. Lord: Burroughs purchased the Haydu plant in 1954 expressly for the purpose of manufacturing and selling new products developed at our Paoli, Pennsylvania facility. One of the first new products, the NIXIE tube, started the division on the road to success. Ed. Lord, Editor, the Burroughs Readout Volume 1, Number 5, July 1972 But I guess it is natural that Burroughs wanted to market the Nixie tubes and their production solely as their own success.

Re: [neonixie-l] Re: Nixie Tube History - help needed
Hello Micah, National Union released the Inditron in 1954. Do you have an add or a press release for that? That would be amazing. I only have the snippet from Popular Science, 1954, that you also have on your VTA website. Haydu was bought by Burroughs in 1954. OK, that is also what I know from several sources. Burroughs released the Nixie and beam switching tube in 1955. That is a crucial point. Do we have any material proving this year? All associated patents are assigned to National Union and Burroughs. The one man most responsible for both the Burroughs beam switching tube and the Burroughs Nixie is Saul Kuchinsky. Kuchinsky was working at National Union during the development of the Inditron, Sadly I could not find a bio on Saul Kuchinsky. Help, anyone? I don't know what sort of retarded licensing agreement Burroughs accepted that resulted in tubes being branded Haydu in the first place, but it was a bad idea.

It has little stickers that say, A subsidiary of Burroughs Corp. stuck on every side of the box. Naturally, it was a gift from Tom Jennings. It includes a data sheet. I could scan it if you're interested. I'd be interested in seeing the datasheet, as well as a photo of the box and tube. The only transitional specimen of 6700 that I have is a first-run Burroughs branded example, which has a white label and the unobtainium MO-10 part number. The box is a standard Haydu box, but it has a white label affixed to the top with typical military white box information. Instead of coming from Plainfield, NJ, its origin is Portland, ME. The shipping date is 6/1957, placing it right at the point where Burroughs abandoned the Haydu branding. OK, I'll see about photographing it. Should be fun. I will also contact Tom Jennings, who wrote that big wps.com decimal counting tube page over 10 years ago, to update his information if you have more substantial printed evidence that Burroughs rather than Haydu developed the beam switching tube. He should be amenable to that, and since his web page is considered the Holy Grail of info for these tubes by the Wikipedia crowd, your outlook on life may improve. We'll see. -- David Forbes, Tucson, AZ -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Nixie Tube History - help needed
Okay, I suppose I'll give it a shot. Great news. Jens: on the subject of Inditrons in the 1940s, that's just wrong. We were once given bad information as to the Inditron's age, and had a date estimate of 1940s up on our site for some time. We have since corrected that information, but it's quite likely that our estimate was regurgitated on various sites. We're the first site to have the Inditron datasheet, and we're the first site to say definitively that the Inditron was released in 1954, with plenty of evidence to back it up. Yes, it makes no sense that the Inditron was released 1940 when the official datasheet is from 1954. It would be interesting to know, though, when the NU engineers started working on a readout tube. There were also no Telefunken Nixies in the 1940s. Yep. A German tube collector told me that he actually has listings of the Telefunken factory in Germany, and the first Nixie tube they produced was the ZM1020 in 1966. Maybe they had some internal discussions and maybe even prototypes of display tubes, that is still not clear.
