Title: Improvements in and relating to cathode ray tubes, image dissecting tubes and the like
IPC: H01J31/42
Filed: 1936-03-02
Abstract: 463,829. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. March 2, 1936, No. 6261. Convention date, March 13, 1935. [Class 39 (i)] In a cathode-ray tube such as an image dissector in which successive elemental areas of a high velocity electron beam are passed through an aperture to produce a varying output, distortion due to secondary electron emission is prevented by collecting slow-moving secondary electrons near the aperture without disturbing the passage of high velocity primary electrons ; or the secondary electrons may be prevented from passing from one anode to another. As shown, an optical image is projected through a lens 13 on to a photoelectric cathode 12, and electrons from the cathode are focused by a winding 21 on to a tubular anode 14, mounted asymmetrically and provided with an aperture 16 behind which a target anode 29 is mounted. Scanning is effected by windings 24, 26. Owing to the asymmetrical mounting of the anode 14, most of the beam follows curvilinear paths, but a part following a rectilinear path passes through the aperture 16 to the target anode. The current through a resistance 34 is a function of the difference in the number of electrons collected by the anodes 14, 29. Secondary electrons connected from the anodes and collected by an electrode 36 at a higher potential than the anodes. In a modification, Fig. 3 (not shown), the secondary electrons are collected by a ring of small diameter mounted around and close to the aperture. In another arrangement, Fig. 2 (not shown), a ring of small diameter is mounted between the anodes and maintained at a lower potential so as to prevent the passage of secondary electrons from one anode to the other.

Abstract: 976,351. Printing surfaces. KOCH PROCESSES Ltd. Feb. 14, 1961 [Feb. 24, 1960]. No. 6522/60. Heading B6C. A method of making a cylindrical printing forme comprises the steps of applying a solvent to a surface of a cylindrical member of a material soluble in the solvent whereby a surface layer of the member is softened, pressing into the surface layer a die constituting a negative of the forme to be made, and drying out the solvent from the surface layer. The die is formed on a metal plate 14 by a known photo-mechanical process involving the use of a gelatine layer made light-sensitive by ammonium dichromate. The leading edge of the plate 14 is fed into the nip of a pair of rollers 16, 17 above which the plate and sheet are separated so as to form a V-shaped channel 18 into which solvent is fed by a pipe 19, the roller 16 being made of P.V.C. constituting the cylindrical member. The solvent is cyclohexanone. The rollers are rotated so as to feed the plate between them, the pattern on the plate 14 being impressed in the roller 16 in the process. The solvent is then dried out of the cylindrical, roller, with the aid of a current of warm air if necessary. In a modification the plate 14 may be omitted, the negative die being formed on the surface of the roller 17. According to the Provisional Specification the process may be applied to making a flat forme.

Abstract: 1,072,202. Brazing. TRANE CO. Feb. 15, 1966 [June 28, 1965], No. 6584/66. Heading B3R. [Also in Division F4] A plate type heat exchanger (Fig. 2, not shown) has corrugated aluminium packing (34) brazed to aluminium plate-type walls (20) in alternate heat exchange passages (24) to extend the heat exchange surface thereof, the other passages (22) being left clear in the finally assembled heat exchanger. In order to maintain the plate-type walls in correct position and to prevent warping during brazing a spacer comprising a corrugated perforated aluminium plate (16) is inserted in these other passages and removed after brazing is complete by pulling, thereby progressively collapsing and withdrawing the spacer. The wall plates (20) and/or the enclosing bars (26, 28, 38) may be clad with a brazing alloy, or brazing alloy foil may be interposed within the joints or an emulsion of brazing alloy may be coated on the areas to be joined and brazing effected by dipping the entire assemblage in a bath of molten salt flux. Undesired brazing of the corrugated spacer plate is prevented by interposing a paper insulator (40) or if an aluminium brazing alloy is used, by coating with a refractory oxide compound containing zirconium oxide. A portion (36) of the corrugated packing is disposed with the corrugations extending perpendicularly from the inlet and outlet openings (30, 32) to ensure proper distribution of the fluid flowing through the passages (22). Inlet and outlet headers (46, 48) (Fig. 6, not shown) may be welded or brazed to the sides of the exchanger adjacent the inlet and outlet openings.

Abstract: 1,210,219. Photochromic materials. HAWKER SIDDELEY DYNAMICS Ltd. 30 Jan., 1968 [10 Feb., 1967], No. 6627/67. Heading C4S. A filter comprises a photo-chromic compound in a solvent, absorption being due only to changes in the triplet state population of the compound. Aromatic compounds comprising two or more condensed or conjugated rings e.g. dibenzanthracene, benzoperylene, chrysene, benzochrysene, naphtho chrysene, coronene, pyrene and picene are dissolved in hexane, ethanol, benzene paraffin or glycerol. Several  compounds may be dissolved to vary the absorption band. To increase the triplet population the compound may contain N, S and O atoms, also compounds which transfer energy to the p.c. compound may be dissolved e.g. an aromatic compound as above benzamide or biacetyl. The triplet lifetime which can be from microseconds to 1 second can be increased by replacing hydrogen in the compound with deuterium or tritium and excluding oxygen and reactive impurities from the solvent. The solution is in a cell connected to a reservoir and may be preceded by filters absorbing wavelengths longer and shorter than those activating the p.c. compound. To reduce convection and diffusion which degrade the filter, fine particles having a refractive index close to that of the liquid may be added.
