Title: Improvements in or relating to electric lamps
IPC: H01J40/18
Filed: 1943-07-29
Abstract: 569,198. Discharge apparatus. LEVY. H. R. July 29, 1943, Nos. 12330, 12331 and 16539. [Class 39 (i)] A lamp consists of an evacuated envelope having on opposite walls a photo-emissive layer 4, Fig. 1, and a luminescent layer 3 arranged so as to have a retroactive effect on one another. In the form shown, the envelope is of cylindrical annular shape, and the central space may be used to house an auxiliary light source such as an elongated incandescent filament lamp for use in combination with the photo-luminescent element and for starting the latter. Alternatively, the starting may be effected by any stray illumination or the incandescent lamp may be replaced by a gas discharge tube with or without a luminescent coating. The photoluminescent element may have an external luminescent layer 7 which is excited by radiation from the inner layer 3, and, in cases where this layer is of the short-wave ultra-violet type, the wall of the envelope is made permeable thereto, and the photo-emissive layer is selected for its response to such radiation. To increase the light output, two or more electrodes may be mounted between the photo-emissive and luminescent layers, Fig. 3 (not shown). These electrodes may be made secondary-electron or photo-electron emissive or both, and the luminescent layer may also be made secondaryelectron emissive. Fig. 4 shows an arrangement in which a gas discharge lamp 17 with a luminescent layer 19 has a window 20 facing a window 23 of a photo-luminescent lamp 18. They are associated with bridging plates 26, 27 of lightdiffusing material such as frosted glass. The lamp 18 may be enclosed by an outer envelope 29 containing a transparent electrolyte 28 which acts as a cooling medium and also may be earthed to act as an electrostatic shield. When used for A.C. working, both the inner and outer walls of the envelope may carry the luminescent material and the photo-emissive material, with or without auxiliary electrodes is mounted intermediate. The layers are made conductive by a backing of metal film or a mesh or similar electrode may be disposed near them. The luminescent material referred to in the description comprise zinc orthosilicate, zinc sulphide activated with copper, a mixture of zinc sulphide and zinc-cadmium sulphide, cadmium tungstate activated with uranium, and zinc sulphide containing two heavy metals such as copper and gadolinium.

Title: Improvements in apparatus for transmitting or receiving coloured television
IPC: H04N11/00
Filed: 1939-04-27
Abstract: 528,090. Television. GENERAL ELECTRIC CO., Ltd., and JESTY, L. C. April 27, 1939, No. 12626. [Class 40 (iii)] Relates to transmitters and receivers for colour television using (a) a cathode-ray tube, supersonic wave cell or other non-mechanical scanning means and (b) a mirror drum, moving film or other mechanical means, the arrangement being such that the scanning of the lines by (a) is correlated with the motion of the lines (or their images) due to (b) so that the lines corresponding to the different elementary colours substantially coincide. As applied to a receiver, the cathode-ray tube 1 has on it three lines R, G, B, perpendicular to the plane of the drawing, which emit red, green, and blue light where the ray moves along them. The drum 3 is rotated at such a speed, and the mirrors thereon are so shaped, that a single face of the drum superimposes on the same line of screen 4 the images of the lines R, G, B traced consecutively. Different faces of the drum superimpose these images on different lines of the screen. As applied to a transmitter, the three lines R, G, B are replaced by three coloured light-sources and the screen 4 by the object to be scanned. If the picture is a moving film, the rotating drum may be unnecessary. If an iconoscope is used as a transmitter, its screen replaces the tube 1, light filters being arranged in front of the lines R, G, B. In this case an image of a line on the object 4 is caused, by the rotation of drum 3 or the movement of the film, to fall cyclically on the lines R. G. B. Specifications 443,896, 508,037 and 527,547 are referred to.

IPC: B41D5/00
Filed: 1916-09-07
Abstract: 109,824. Printing Machinery Co., (Wood, H. A. W.). Sept. 7, 1916. Printing-surfaces; stereotype. - In a machine for casting and finishing curved stereotype plates, the severed tails are lifted automatically into a shoot along the top of the inclined shaving-arch and from the shoot are automatically returned to the melting-pot by a conveyer. As shown, the tail T severed from the plate P by a cutter 56 is lifted into line with a shoot 126 on the top of the inclined finishing-arch F, and then slides down the shoot until one leading corner strikes a projection 127, Fig. 3, thereby turning the tail through about 90 degrees. The tail continues to slide down an extension 128 of the shoot less steep than the part 126 until a second projection 129 turns the tail through a further 90 degrees so that the heavier end of the tail becomes the leading end. The tail then slides down the incline 130 into a conveyer 131 which returns it to the melting-pot. The means for lifting the tails into the shoot comprises arms 120, 121 pivoted to a yoke 115 which is reciprocated by linkage 117, 113, 111 and a rotating cam 23. The arms 120, 121 are pressed towards each other by springs 125 to an extent limited by stops 123, 124 and are spaced apart sufficiently to allow a plate to pass between them into the arch. One arm 120 is higher than the other so as to tilt the plate to clear parts of the mechanism.

Abstract: 400,685. Gun-fire control. VICKERSARMSTRONGS. Ltd. and WATSON, J. P., Vickers House, Broadway, Westminster. May 4, 1932, No. 12881. [Class 92 (ii).] Apparatus such as that described in Specifications 374,058 and 374,059 for controlling the fire of anti-aircraft guns mounted on unstable platforms is simplified for use with low-angle fire guns such as ordinary naval guns. In the apparatus shown, which is similar to that described in Specification 374,058, a gyroscopically-stabilised disk 4 operates a pick-up device 1 moving in a vertical plane parallel to the trunnion axis to convey the angle of cross-level to the translatory support of camoids 12, 13, which are rotated in accordance with gun elevation obtained from the calculator 8 by a shaft 14. The camoid 12 gives the cross-level correction to gun training which is superposed on the normal gun training angle given by a shaft x and conveyed to a transmitter 17. The camoid 13 gives the cross-level correction to gun elevation which is superposed on the angle of gun roll given by a pick-up 3 engaging the disk 4, the combined correction thus obtained being superposed on the normal gun elevation angle given by the shaft 14 and conveyed to a transmitter 27. A third pick-up member 2, moving in a vertical plane kept parallel to the director sight by the rotation of a shaft y, convoys the correction for " sight roll " to the director sight A. The latter pick-up may bo dispensed with when the angle z is small, the pick-up 3 being then also connected to the director sight.
