Title: Means for reproducing film pictures by means of a screen of electric lights
IPC: G09F13/28
Filed: 1932-12-07
Abstract: 411,835. Television. ROSENBERG, H., 7, Parkstrasse, Dahlem, Berlin. Dec. 7, 1932, No. 34747. Convention date, Oct. 18. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 8, 1933.] [Classes 40 (iii) and 40 (v).] In an arrangement for reproducing film pictures on a screen of incandescent lamps individually associated with light-sensitive cells controlled by the picture to be transmitted, the switching on and off of the lamps are effected by thyratron valves directly controlled by the cells. The Figure shows the circuit for one lamp of the screen. When light passes through the film picture on to the cell 1 the grid 3 of the thyratron becomes less negative and the lamp 9 in the plate circuit is illuminated. The plate circuit of the tube is fed with alternating current so that the lamp 9 is extinguished during the negative half cycles and is not illuminated when light does not pass through the film on to the cell 1. The Specification as open to inspection under Sect. 91 describes the use of photoelectric cells with a "glow-relay" action in combination with an interrupter. The use of evacuated tubes with a coating of lightsensitive material on the glass walls is also described. This subject-matter does not appear in the Specification as accepted.

Title: Automatic polarization analyser device
IPC: G01N21/21
Filed: 1975-08-22
Abstract: 1525283 Polarization analyzers NIPPON KOGAKU KK 22 Aug 1975 [29 Aug 1974] 35011/75 Heading G1A An automatic polarization analyzer of known type which measures phase difference # and azimuth # is provided with an additional servosystem which resets the analyzer if the value of # is more than 180 degrees, thus increasing the range of measurement up to 360 degrees. Basic analyzer: Figs. 1A, 1B show the basic analyzer applied to reflection measurement of a surface 6. The optics comprise source 1, lens 2, filter 3, polarizer 4, quarter wave plate 5, adjustable half wave plate 7, phase and azimuth modulator 8-10 (respectively a KDP element, a quarter wave plate, and another KDP element), analyzer 11, lens 12 and photo-detector 13. The detector signal is amplified at 14 and synchronously demodulated at 15, 16 against signals driving the modulator, the demodulated information being fed via preamplifiers 17, 18, switches S1, S2 and servo-amplifiers 19, 20 to servos 21, 22 which adjust the polarizer 4 and half wave plate 7 to a null position. The position of these components 4, 7 are found by potentiometers 40, 40 and are processed to give the system output. The angular position indicated by 40 is designated #p, and this is processed to give # = 90 + 2#p at 42. The angular position of 41 is # H , and this is processed at 44 to give # = |2# H |. Range extension: the basic analyzer can rotate component 4 by + 45 degrees only, which limits the # measurements to the range 0-180 degrees. To extend this range the component is provided with limit switches which activate flip-flop 33 when the rotation is Œ 45 degrees. This flip-flop operates switches S1, S2 to connect servos 21, 22 to angle changing circuits 38, 39, and also, via flip-flop 36, to reverse the modulator drive at 37. Angle changing circuit 38 drives servo 21 until pot 40 indicates that the other extreme position of component 4 has been reached; angle changing circuit 39 measures the position of component 7 indicated by pot 41 (say-this is + # H ) and drives servo 22 until component 7 reaches a complementary position (-# H ). When both components have been so changed, circuits 38, 39 reset the flip-flop 33 via gate 49. The value of # H  is positive for 0 # # # 180, and negative for 180 # # # 360; the sign of # H  is sensed at 46 and the value of # found at 42 is increased by 180 degrees at 43 if appropriate. The final value of # is displayed at 47, while # is displayed at 45. Details are given of the limit switches, the angle changing circuits, and the modulator oscillator, Figs. 3, 4, 5, 6 and 2 (not shown). In another embodiment, the angle changing circuits restore the components 4 and 7 to the 0 degree position, Figs. 7A, 7B (not shown).

Title: Improvements in or relating to devices for determining the content of water vapour in a gas flow
IPC: G01N7/10
Filed: 1958-10-31
Abstract: 846,648. Hygrometric apparatus. PHILIPS' GLOEILAMPENFABRIEKEN N. V. Oct. 31, 1958 [Nov: 4, 1957; Dec. 26, 1957], No. 35027/58. Drawings to Specification. Class 97(3) Water vapour in a gas flow is determined by removing any free oxygen present in the gas flow; measuring' any free hydrogen in the gas flow or removing said hydrogen; decomposing the water present in such a manner that the oxygen of the water vapour is chemically bound and the hydrogen is formed as a gas and determining the pressure of the hydrogen liberated from the water vapour after diffusion through a semi-permeable wall, such as platinum, as a measure of the water vapour originally present in the gas. If the partial pressure of the free oxygen present in the gas is less than half of the partial pressure of the free hydrogen in the gas the free oxygen need not be removed prior to measurement. An apparatus for measuring the water content in a flow of gas comprising means for decomposing the water vapour to produce hydrogen on one side of semi-permeable wall substantially preventing a passage of gas other than hydrogen and means for applying suction to cause said hydrogen generated by the decomposition to diffuse through the wall to a pressure measuring device. Free hydrogen may be removed from the flow if possible by selectively diffusing free hydrogen through a second semi-permeable wall. If the gas has a free oxygen content this oxygen must be removed prior to decomposing as the semi-permeable wall has a catalytic effect to combine oxygen and hydrogen so the gas must be reduced to a partial pressure less than half that of the free hydrogen of the gas flow. The semi-permeable walls may be palladium or heated silver while the water vapour is decomposed by chemical reaction with a reagent consisting of a hydride of an alkali metal or alkaline earth metal with a finely-divided iron, copper or other suitable metal or carbon, silicon, boron or other suitable non-metal or a sub-oxide at a suitable temperature at which the oxygen of the water is chemically combined with the reagent and at least part of the hydrogen is quantitatively liberated.
