Title: Method for producing self-spacing solder composition
IPC: H01L35/34
Filed: 1966-07-27
Abstract: 1,112,693. Soldering. WESTINGHOUSE ELECTRIC CORPORATION. 27 July, 1966 [23 Nov., 1965], No. 33710/66. Heading B3R. A method of producing a self-spacing solder of predetermined final thickness comprises the steps of preparing a melt of a solder metal component, adding thereto powdered metallic particles which are insoluble in but wettable by the solder, the particles being of average overall size greater than the final thickness, solidifying to form an ingot and rolling down the ingot to form a strip of the required thickness. The solder may be of lead, tin, bismuth, silver or of an alloy of one or more of these metals while the particles may be of iron, cobalt nickel or refractory metal and for a joint which is optimally to be spaced 0À003 to 0À005 inch the powder particles must pass a 30-mesh screen and at least 85% be retained on a 325-mesh screen, the preferred range is 40 to 60 mesh. To prepare the solder the metal particles are heated in a reducing gas to remove oxide, coated with a flux, and added to and dispersed in the molten solder component and then cast in moulds ¥ to 1 inch in thickness; the resulting bars are rolled to the required thickness e.g. 0À005 inch. A wetting agent is preferably added to the solder melt after the particles have been added. The wetting agent may be phosphorus, lithium, caesium, sodium, calcium or magnesium and may be present in an amount up to 0À8% by weight. Specific solder compositions given are: The solder compositions referred to find application in the bonding of thermoelectric materials such as lead telluride, germanium bismuth telluride, germanium telluride and zinc antimonide to metal contacts e.g. tin-coated iron contacts. Soldering may be carried out in an oven or furnace in a stream of reducing gas such as hydrogen.

Abstract: 1,237,281. Hardening concrete. DOW CORNING CORP. 16 July, 1968 [15 Aug., 1967] No. 33775/68. Heading C1H. The surface of concrete, within about 2 hours after screeding, is coated with a silane QSiX 3 , wherein Q is a hydrocarbon or substituted hydrocarbon radical and X is a readily hydrolysable radical, an alkali metal monoalkyl siliconate having from 1-4 carbon atoms in the alkyl group, or an aqueous solution of the products formed by hydrolyses of such a silane or siliconate to increase the resistance of the surface to scaling and spalling.

Title: Improvements in feed devices for automatic guns supplied with ammunition in the formof a cartridge belt
IPC: F41A9/51
Filed: 1955-12-06
Abstract: 781,748. Automatic guns. BREVETS AERO-MECANIQUES SOC. ANON. Dec. 6, 1955 [Dec. 16, 1954], No. 35003/55. Class 92. Relates to an automatic gun provided with means which obviate the jerky pull on the cartridge belt by the feed mechanism of the gun. According to the invention a fly-wheel 6, Fig. 1, is coupled in rotation by means of a torque limiting device with sprocket wheels 7 in mesh with a portion of the belt 4 located in a guide passage 5, the arrangement being such that during the time intervals for which the cartridge engaged by the belt feed mechanism 2 is stationary, sprocket wheels 7 push the cartridges towards the mechanism 2 and, during the time intervals when the cartridge belt is pulled by mechanism 2, wheels 7 partly exert a braking action on the cartridge belt. The clearance between the belt 4 and the inner walls of the passage 5 are such that when the feed mechanism 2 is stopped, the portion D of the belt can only take a slightly zig-zag shape, thus stopping the part of the belt engaged by the wheels 7 a short time after stopping of the mechanism 2. The shaft 8 of the wheels 7 is journalled in frame elements 9, Fig. 2, rigid with passage 5 and one end of the shaft 8 is coupled with the flywheel 6 through an epicycloidal gear, comprising, a sun-wheel 11 on the shaft 8, planet wheels 15 journalled in the flywheel 6 and a further sun-wheel 16 carried by a sleeve 17 freely rotatable around shaft 8 and bearing axially against the fixed frame through a thrust bearing 18. Annular friction discs 19, 20 alternately carried by the sleeve 17 and fixed frame constitute the torque limiting device; the limit of which can be varied by a nut 23 and spring washer 22. At the start of firing, the wheels 7, shaft 8 and planet wheels 15 start rotating and through sunwheel 16 exert a high torque on the sleeve 17. The friction between the discs 19, 20 oppose the rotation of the sleeve 17 and the planet wheels 15 gradually start the flywheel 6 rotating until sleeve 17 is stationary, and the wheels 7 rotate at nearly constant speed. On ceasing firing, the rotation of the flywheel is braked by friction between the discs 19, 20 which slip with respect to one another and the flywheel is in turn stopped.

Abstract: An electrophotographic element consists of an electrically conductive base, a charge-generating layer and a charge-transporting layer. The photoconductive charge-generating layer does not require a binder matrix. It consists essentially of organic dyes from the group of monoazo dyes, disazo dyes or derivatives of squaric acid, which are soluble in a solvent containing a primary organic amine. For producing the element, the charge-generating material is dissolved in a solvent containing a primary organic amine and the solution is applied to the base. The charge-transporting layer then goes on top of the dried layer. Polymers can also already be introduced at the same time into the solution.
