Title: Process for Finishing Leather
IPC: C14C11/00

Abstract: 1,163,443. Finishing leather. FARBWERKE HOECHST A. G. Sept. 16, 1966 [Sept. 16, 1965], No. 41505/66. Heading C6C. In a process for finishing leather, an aqueous solution or dispersion of a non-thermoplastic product resulting from the condensation of an alkylene imine with urea or a urea derivative and functioning as a non-thermoplastic binder, is applied to a surface of the leather, which surface is subsequently hardened by treatment, e.g. spraying, with an aqueous formaldehyde solution e.g. containing between 5 and 30%, by weight, of formaldehyde and having a #H between 3À5 and 6‹5. The aqeuous formaldehyde may contain a water-soluble chromium salt such as chromium sulphate. The condensation product may be mixed with one or more than one other non-thermoplastic binder selected from: oxethylized casein, albumin and synthetic polymers, e.g. derived from styrene and maleic ankydride, or from acrylonitrile. The weight ratio of the condensation product to the other non-thermoplastic binder or binders may be between 1:2 and 1:5. Alternatively, i.e. when hot-ironing forms part of the finishing process, the condensation product may be mixed with a thermoplastic binder, e. g. a copolymer of butyl acrylate, vinyl acetate and vinyl chloride respectively in the proportion of 50:30:20, by weight, and, if desired, with one or more of the above - mentioned other non-thermoplastic binders. The alkylene imine may be ethylene or propylene imine or a dito hexa-meric polymer thereof. The urea derivative may be ethyl, butyl, phenyl or benzyl urea. The condensation product may be prepared by condensing one mole of urea or urea derivative with 0À5 mole to 4 moles of the alkylene imine. The aqueous solution or dispersion of the condensation product may contain ammonia or mono-, di- or triethanol amine, and one or more of the following substances: a coating colour, e.g. iron oxide red, a brightening agent, a softening agent, e.g. sulphonized castor oil. The aqueous solution or dispersion may be applied by brush, plush-board or spray-pistol. After the form aldehyde hardening treatment, the leather is dried and glazed or pressed, e.g. in an ironing press, at 70‹C. and 150 atmospheres gauge pressure.

Abstract: 1,000,611. Batteries. GLOBE-UNION Inc. Nov. 29, 1961 [Aug. 2, 1961], No. 42613/61. Heading H1B. [Also in Division B3] Connector straps of adjacent cell stacks of a storage battery are welded together through a hole in a partition wall that separates them so that the hole is sealed. Strap 22 has a recessed projection 32 which passes through a hole 36 in partition wall 14 and engages a conical projection 30 on a strap 20. The projections 30, 32 are first forced together by jaws 42, are then heated by passing an electric current through them, and are finally cooled, whilst still under compression, by passing coolant through conduits 46 in the jaws 42, to produce a sealed connection. The projections may have flat mating surfaces (Fig. 11, not shown), or one may be flat and the other provided with a plurality of protuberances (Fig. 13, 14, not shown), or one projection similar to projection 32 may engage the point of a recessed conical projection (Fig. 7, not shown). In Fig. 16 (not shown) the straps are joined by welding them to a separate connector which passes through the hole in the partition. If the partitions are of rubber based material a chemical bond due to carbonization of the portions is produced.

Abstract: 954,558. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 13, 1960 [Dec. 14, 1959], No. 42784/60. Heading H1K. A tunnel diode is made by placing a heavily doped semi-conductive wafer 30 of one conductivity type, opposite type doping pellet 32 and ohmic contact 30 in a cylinder 12 and between pistons 14, 16 which exert pressure on the assembly, an electrical current being passed through the assembly to heat it very rapidly so as to produce an abrupt junction. The cylinder and pistons must be non-reactive with the material of the diode and of high resistance; carbon and molybdenum are suggested. Connection may be made to the pistons or they may be clamped between electrodes. Material suggested for the wafer 30 are silicon, germanium, silicon carbide, gallium arsenide, gallium antimonide, indium arsenide and indium antimonide. The doping concentration in the wafer must be from 6 x 10<SP>19</SP> to 10<SP>23</SP> carriers per cc. and the resistivity 10<SP>-3</SP> to 10<SP>-4</SP> ohm centimetres or less. Materials for pellet 32 to make the wafer P type are boron, aluminium, gallium and indium; those to make the wafer N type are phosphorus, arsenic and antimony. Wafer 30 may be cut from a single crystal grown from a doped melt or intrinsic material may be doped from a vapour. Pellet 32 may include relatively neutral metals such as gold and silver. Suitable alloys for pellet 32 include gold and arsenic and gold and boron. Pellet 34 which forms the ohmic contact should comprise a neutral material with a dope of the same type as the wafer or may be of gold or gold-silver alloys with intrinsic silicon. The heating current may flow for less than a second to 60 seconds. A temperature of 700-1100‹ C. is satisfactory for silicon and 300-600‹ C. for germanium. A non-resistive powder 40 may be packed in the jig to hold the wafer and pellets in place during fusion. Three electrode devices may be made.
