Abstract: 1,219,112. Surface deformation imaging. RANK XEROX Ltd. April 25, 1968 [April 27, 1967J, No.19667/68. Heading G2H. In a surface deformation imaging process a deformable thermoplastic layer has a thin film of higher viscosity material having a thickness of up to 0À05 microns formed on one surface, an electrostatic latent image is formed on the film, the plate is heat softened to form a surface deformation image, and this image is erased and subsequent ghost images prevented by heating the plate to a temperature at least 1À5 times the softeningtemperature. The thin film may be formed in situ by exposure to U. V radiation, X-rays, beta or gamma rays, high voltage or corona discharge or chemical treatment, or by deposition of a second material e.g. by spraying, dip-coating or painting the thermoplastic layer. The thermoplastic layer may overlie a photo-conductive layer, in which case the latent image is formed by uniform corona charging, imagewise exposure to an original and uniform recharging. The recharging step may be omitted if photo-conductive material is dispersed throughout the thermoplastic, and if the photo-conductive material is omitted, the thermoplastic is charged in imagewsie configuration, e.g. by using a shaped electrode. The thermoplastic may be non-polymeric e.g. esters of abietic and related acids, or polymeric e.g. polystyrene, copolymers of styrene, indene polymers, vinyl polymers or polyesters.

Filed: 1961-05-31
Abstract: 946,806. Discharge tubes. McGRAWEDISON CO. May 31, 1961, No. 19710/61. Heading H1D. [Also in Division G1] In an ultra-violet detector tube, within and on the boundary of the region in which an emitted electron is capable of triggering an avalanche discharge, the two electrodes consist solely of one or more thin cylindrical elements having smooth uniform surfaces with no discontinuities, abrupt edges or corners, so as to avoid any electric field disturbances. As shown, a tube suitable for either A.C. or D.C. operation comprises two tungsten-wire electrodes 11 welded to tungsten or " Kovar " (Trade Mark) supports 12. The borosilicate glass or pure fused quartz envelope 13 contains hydrogen at a pressure of 10 cm. of Hg to obtain a striking voltage of about 700 volts under U-V excitation. The tungsten wire is electro-polished in a sodium phosphate solution against a steel electrode and washed prior to being welded to clean support rods. This assembly is again washed and electro-polished, specific details being given, before being mounted in a clean envelope. The electrodes are outgassed by heating and are then bombarded with positive hydrogen ions, the glass envelope acting as a getter for impurity atoms. In an alternative arrangement the electrodes comprise sets of parallel wires 23, 24, Fig. 2. In a tube for D.C. operation a straight wire electrode may be arranged coaxially within a helical wire electrode, Fig. 3 (not shown). To avoid contamination of the electrodes by positive ions during operation, the electrodes may be heated to a temperature of between 300‹ and 400‹ C., but below that which would cause thermionic emission. Platinum and rhenium as electrode materials are also said to meeting the spectral response requirement.

Filed: 1932-07-14
Abstract: 404,350. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, LUNNON, F. C., Westdene, Roxwell Road, and TRUMP, E. H., Meadowsweet, Vicarage Road, both in Chelinsford. July 14, 1932, No. 19969. [Class 40 (v).] Relates to modulating systems of the kind described in Specifications 351,051 and 388,066 in which radio-frequency valve stages function as amplifiers during speech transmission and as absorbers of the HT supply during silent intervals ; and consists in combining such a system with a grid-leak modulating-valve shunted by a source of direct voltage derived by rectification of the carrier wave. The carrier wave amplifier may comprise a push-pull pair of valves 1a, 1b fed from a previous stage through condensers 19, 20 and including the modulating- valve 5 in a common portion of the grid-cathode circuits. Speech is applied to the grid of the valve 5 through a transformer T. The unmodulatedcarrierwave from the preceding stage is also applied through variable coupling- condensers 21, 22 to the plates of diode or other rectifiers 25, 26 the cathodes of which are joined. A smoothing condenser 37 and resistance 29 are connected between the cathodes and the mid-point of a choke 27 connecting the anodes, and the direct voltage appearing across the whole or part of the resistance 29 is applied through a series resistance 36 across the anode and cathode of the modulating-valve 5. The rectifier cathodes are heated by out-of-phase currents from the supply mains, in order to reduce undesired hum. Rectified speech currents are applied through a delay network 15, 16 to the grid of an auxiliary valve 14 having a tapped resistance 12 in its plate circuit. The tapping 11 is connected in the grid circuit of the valves 1a, 1b and other tappings 17, 18 are connected to the grid circuits of preceding radio-frequency stages. When speech ceases, current flows through the resistance 12 and the voltages applied by the tappings cause the radio-frequency valves to cease functioning as amplifiers whilst permitting them to absorb current from the HT supply. During such silent periods, the absence of the carrier wave will remove the direct voltage across the resistance 29. Specification 375,725 also is referred to.
