Filed: 1937-05-10
Abstract: 500,613. Photographic colour development. KODAK, Ltd. MAy 10, 1937, No. 35098/38. Convention date, May 9, 1936. Divided out of 500,826. [Class 98 (ii)] In a process of three-colour photography wherein component colour images in three silver halide emulsions on a single support are processed to coloured images, a dye image of improved gradation is produced by subjecting a developable silver salt image to the action of a colour developer containing also a non- coupling and non-colour-forming developing agent and subsequently removing the silver from the dye image produced. The component colour images may be formed in three layers of differentially sensitized silver halide emulsion on a single support or in two layers, one of which consists of a not specially sensitized silver halide emulsion while the other consists of a mixture of grains of silver halide emulsion respectively sensitized to the red and green regions of the spectrum. The colour developer may include either (a) a developing agent of which the product of oxidation on development couples with unoxidized developing agent, (b) a developing agent, for example a leuco dye, oxidized directy on development, or (c) a developing agent of which the oxidation product on development couples with a colour former. The addition of sulphite in colour development by coupling is omitted or limited to a minimum. The component images may be reversed silver salt images or images produced by bleaching developed and fixed images. Specifications 498,869, 498,870, 498,871, 498,875, 501,000, 501,001 and 501,002 are referred to.

Abstract: 805,840. Lamp-holders. CARR FASTENER CO. Ltd. Dec. 3, 1956 [Dec. 8, 1955], No. 35305/55. Class 38 (1). In order to minimize vibration of a lamp a inserted in a holder, the holder body 1, e.g. of polythene has a resilient sleeve 6 moulded integrally so that the upper edge of the sleeve contacts the glass envelope of the lamp. The sleeve is of elliptical shape (Fig. 2, not shown) but may be of any shape to correspond with that of the lamp envelope. An insulating plate 7 engages in notches 9 of the contacts 4 to retain them, a ring 8 attaching the plate 7 to the holder body having resilient fingers 10 for snap-fastener engagement in an aperture in a support. In the embodiment of Fig. 3, a wall 6a is formed integrally with the body and is formed with slots 12 and shoulders 13 to make snap-fastener engagement with the wall of an aperture. The body of the holder may, alternatively, be moulded from natural or synthetic rubber. The construction may also be applied to valve holders.

Title: High energy density electrochemical cell
IPC: H01M6/04
Filed: 1973-07-26
Abstract: 1406188 Cathode for high energy density battery J C BOGUE 26 July 1973 35621/73 Heading H1B The cathode of a cell capable of delivering very high current and energy per unit weight and volume comprises a base element, e.g. of stainless steel sheet, having a sintered coating of nickelous ammonium sulphate on which is supported the cathodic active material. The coating greatly enhances the cathode activity. Preferably, the stainless steel base element is initially heated in a hydrogen atmosphere to remove surface oxides and is then sputtered in a vacuum with nickel carbide to form a thin surface coating on which the sintered coating of nickelous ammonium sulphate is subsequently formed. Fig. 20 shows a section through cells forming part of a multi-cell battery, each cell comprising a cathode base plate 113 and a magnesium anode plate 111 each plate having perforations 116 and the shape shown in Fig. 19. The plate 113 is of stainless steel having on both sides the coating of sintered nickelous ammonium sulphate and pasted on both sides with the cathodic active material 114 which enters the holes 116. The paste 114 may comprise mercuric oxide mixed with carbon black and a binder such as carboxymethyl cellulose. Fibrous separation 115 supporting the electrolyte are applied against both surfaces of the magnesium anode plate 111 and enter the holes 116 in the latter. The electrolyte may be an aqueous solution of magnesium perchlorate and lithium perchlorate. In another embodiemnt, Fig. 21, the cathode and anode are both in the form of bent strips 121, 122 entwined together. Reservetype batteries incorporating a cylinder-shaped stack of cells are described with reference to Figs. 1-13 (not shown). The cells of these batteries have cathodes as previously described. The electrolyte is contained in a frangible housing which is broken by release of a spring- biased plunger. Figs. 14, 15 show a reserve-type battery of flat rectangular-pack construction. The battery electrodes 51 are contained in a flexible plastics case 50 together with a thin frangible envelope 53 of glass containing the electrolyte. To activate the battery, metal plates 56 on a hinge 55 are folded over on to the case 50 to break the container 53.

Abstract: 864,124. Electric heating units. ELECTROFILM Inc. Nov. 18, 1957, No. 35845/57. Class 39(3). An electric heating unit includes a heating element formed as a conductive mesh composed of interwoven longitudinal and transverse conductive strands, an insulating layer bonded to the mesh, and electrical connection means at spaced locations, the mesh being in elongated strip form having a number of parallel extents which occupy the greater part of the area of said insulating layer between the outermost edges of said extents. As shown, Fig. 3, a heating unit comprises an elongated woven wire mesh conductor 13, e.g. of nickel-chrome alloys, tungsten alloys, stainless steel and the like, sandwiched between and bonded to two insulating layers 12 and 14, e.g. of thermal setting plastic, the whole being bonded to a metallic or other rigid support 11. Each layer 12 and 14 may consist of one or more preformed sheets of reinforcing fibre, e.g. glass cloth, impregnated with non-conductive plastic. A flexible element, Fig. 4, comprises a conductive mesh 18 sandwiched between one fabric reinforced insulating layer 19 on one side and two similar layers 20 on the other side. Terminal arrangements for supplying current to the mesh may comprise terminals of the mesh itself extending out of the insulation as at 16, exposed areas of mesh to which lead wires are soldered or spot welded, terminal lugs in direct contact with the mesh, or insulated terminal posts extending through the laminations with a washer in electrical contact with the mesh (Fig. 8 not shown). Where the mesh has a reduced cross-sectional area, e.g. due to the provision of terminal posts or fixing studs as shown in Fig. 5, conductive patches 26, e.g. of mesh, or of a conductive coating on the mesh or of finely divided conductive particles in a non-conductive binder, are provided in contact with the mesh to compensate for the resulting increased resistance of the mesh. The laminations after being bonded may be coated with an insulating varnish. An element of the type shown in Fig. 4 may be given a metallic foil surface on one or both sides.

A servo system comprises a jet pipe 22 controlling the flow to opposite ends of a piston 29 in response to an input signal to a torque motor 27. A feedback is provided by a coupling means 14 which comprises a first spring 41 having a low spring constant which is connected between a link 43 and a member 59 slidable in a fixed housing 52 and a second spring 51 having a high spring constant which is arranged between the member 59 and the housing 52. The movement of the member 59 in response to movement of the piston 29 is thus less than the movement of this piston due to the difference in the spring constants. The member 59 may be connected directly to the jet pipe 22 or through a spring 71. An adjustable spring 32 sets the wall position of the jet pipe. The coupling means may be arranged in a mechanical input to the control member of the system.
