Who invented the first practical (working) camera tube?

[Stears555]

Hello guys!

Are there any engineer who can read patents of old technologies?

For example: patents from the 1920s & 1930s.


Thank you for your reply!

Who was the determinant person? Kálmán Tihanyi? Zworykin? Or Farnsworth?

Online listings of US patents only go back as far as 1976, IIRC. If you wanted to go back farther, you'd have to request hard copy be sent to you.

Who is on the patent and which one made the most sense at the time hardly matters now, as ALL of those patents have long expired and are in the public domain. That has both muddied the waters and made the technology moot.

While wikipedia may have additional and/or contrary things to say about it, what is mostly taught in media studies is that it was (simultaneously) created by Farnsworth and Zworykin.

CCD & CMOS digital sensors are what (nearly) everything current is based on, and there is very little that those technologies have in common with the older ones. By now, I would expect CCD patents to also have expired. CMOS probably still has certain patent features in effect.

The ability to "read" a patent is nothing special; it is just a combination of very strict and deterministic scientific terminology along with exacting legalese, done in a predictable format. If you are quite fluent in English, you shouldn't have any trouble with patents, though it will be SLOW going at first while trying to understand which element or process is being referred to. This, of course, assumes you understand the underlying science described by the patent.

If you are trying to drum up a flame war about "who was the originator", don't waste your time - no one cares (except maybe historians and the descendants of those characters involved).

According to UNESCO (United Nations) the credit goes to Tihanyi's "radioskop")

10th page of 52 pages, Radioskop patent.

Cute font they have there at UNESCO...

Wow! He invented the first plasma TV in 1936, and the first infrared Camera too.

A page from the Plasma TV patent 1936:
Plasma TV description:http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&v ed=0CD0QFjAC&url=http%3A%2F%2Ftihanyi.sci-tech.hu%2Fflat-panel_tv_en.pdf&ei=Oqk8Ur_oLqWI4gSR54DwDw&usg=AFQj CNHS7x0sXfEU4NrbTBt7X633Nfa6JQ&sig2=yyuADca-gK9Xgvz_WjL19g&bvm=bv.52434380,d.ZGU



In 1936 Tihanyi described the principle of "plasma television" and conceived the first flat-panel television system.[14] It involved a single “transmission point” being moved at great speed behind a grid of cells arranged in a thin panel display, which would be excited to different levels by varying the voltages to the point[15]



From 1929, Tihanyi worked on television guidance for defense applications, building prototypes of a camera for remotely guided aircraft in London for the British Air Ministry, and later adapting it for the Italian Navy.[10][11] In 1929, he invented the first infrared-sensitive (night vision) electronic television camera for anti-aircraft defense in Britain.[12][13]

(Tihanyi as a scientist of the British Air Ministry)

In 1940, Tihanyi returned to Hungary and in late 1941 began construction of the full-scale prototype. At the same time, he became involved with the Resistance and developed an intimate friendship with its leader Endre Bajcsy-Zsilinszky. In 1941, he was briefly arrested in connection with propaganda material against Hitler and Basch; in 1943 his home was searched.
Following Hungary's March 19, 1944 occupation by the Germans, Kalman Tihanyi was arrested by the Gestapo and imprisoned at the Margit Ring prison. Although he survived five months of solitary confinement, starvation and interrogations, following the failed attempt at armistice on October 15th by Regent Miklós Horthy and the installation of the Szálasi government, like the rest of the Resistance, he went underground.


He was one of the greatest man of television technology.
Wasn't he?

Are you related ? I see you're from Budapest .

Would you be as fascinated if he was from another country

In electro technology, we were better than US and Germany

1.We invented the first electric motor (1828 Jedlik)
In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of commutator, he called his early devices as "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no PMs, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings. [5] [6] [7] [8] [9] [10] [11]


2. We invented the transformer:

The prototype of the high efficiency, closed core shunt connection transformer was made by the Hungarian "Z.B.D." team (composed of Károly Zipernowsky, Ottó Bláthy and Miksa Déri) at Ganz Works in the autumn of 1884.[4][5] The new Z.B.D. transformers were 3.4 times more efficient than the open core bipolar devices of Gaulard and Gibbs.[6] Transformers in use today are designed based on principles discovered by the three engineers.[7] Their patents included another major related innovation: the use of parallel connected (as opposed to series connected) power distribution.[8][9] Ottó Bláthy also invented the AC electricity meter to complete the competition of AC and DC technology.[10][11][12][13][14] The reliability of the AC technology received impetus after the Ganz Works electrified a large European metropolis: Rome in 1886.[15]


3. We built AC power Plants before siemens (germany) and westinghous (usa) )

We have higher ratio of scientific types of Nobel awards per capita than Germany USA or France ))

So our science was recognized very well by international organizations )) :PPPPPPPPPPPPPPPPPPP

Leo Szlárd invented the A-bomb, (Szilárd-einstein letter started the Manhattan project) Teller invented the H-bomb.

Yes, the Austro-Hungary world was great

And last but not least,

Enjoy

Yes, we are very proud of our scientific past (despite now we are a little country and nation we have comparable past in innovations to great powers

Just read this::

https://en.wikipedia.org/wiki/Science_and_technology_in_Hungary

))

We built the first steam engine in continental Europe in 1735.

BME University is considered the world's oldest Institute of Technology which has university rank and structure. It was the first institute in Europe to train engineers at university level.[2]


So, the first engineer university was born in Hungary :P

This thread really belongs in off topic. We don't maintain a twentieth century history forum here or one devoted to Hungarian nationalism.
