Patent GB-876034-A (GB)
Title: New resin composition
Inventor: TAYLER FREDERICK MAURICE
IPC: B01J41/14
Filed: 1958-10-10
Abstract: A resin composition comprises an anion-exchange resin containing adsorbed borohydride ions.  Resins specified are cross-linked polystyrenes containing secondary and tertiary amino groups and quaternary ammonium groups, and weakly basic phenol-formaldehyde resins.  The compositions may be obtained by contacting the anion-exchange resin with a solution of a borohydride, e.g. sodium, potassium or calcium borohydride, in a suitable solvent, e.g. water, tetrahydrofuran or alcohols.  After preparation the product may be stabilized by wetting it with a solvent and storing it at below room temperature.ALSO:Malachite green is reduced to its leucocompound by means of an anion-exchange resin containing adsorbed borohydride ions.ALSO:Borohydrides of metals, e.g. sodium and lithium, complex metal cations and ternary sulphonium cations are prepared by bringing a solution of a salt whose borohydride is to be obtained into contact with an anion-exchange resin containing adsorbed borohydride ions. Examples describe the preparation of sodium and lithium borohydrides by the above method using aqueous sodium chloride and a tetrahydrofuran solution of lithium chloride.

Class 40(5) In a radio receiver for multiplex frequency shift telegraph signals an oscillator 0 3  rich in harmonics, e.g. a pulse generator, of frequency equal to or a sub-multiple of the common frequency spacing 340 c/s of the frequency shift signals mixes its output with the received keying frequencies in a mixer M 3  to derive a single common sum or difference frequency which, after selection by a filter F 2  and limiting at B, passes to a frequency discriminator D whose output, by controlling the frequency drift of a local oscillator O 1 , stabilizes the frequency output of the first mixer M 1 . The latter output then passes through upper or lower sideband filters F 1  to a further modulator M 2  and local oscillator O 2 , reducing the output telegraph frequencies to audio range.

[Class 83 (i)] In a method of casting, an additional piece or pieces of metal is cast substantially at the same time as the main object, and is so disposed in relation thereto and is of such shape and dimensions as to produce a predetermined temperature gradient in the object whereby the metal freezes progressively in a desired direction. The extra pieces may be cast either integrally with or separately from the main object.. Wedgeshaped pieces e, Fig. 2, are cast at the same time as the main plate or bar-shaped casting a, the freezing of which then occurs progressively from the bottom upwards. In a modification the additional portion e of similar longitudinal section, is tubular. In a further example the additional piece e, Fig. 5, is of annular form, surrounding a constriction f of the main casting a. The Provisional Specification states that the additional pieces may be cast slightly in advance of the main objects.

Title: Improvements in or relating to processes of preparing synthetic resins and the resins resulting from said processes
Filed: 1947-12-17
Abstract: Terpolymers are prepared by polymerizing in aqueous emulsion a mixture comprising, by weight, 10-85 per cent of a polymerizable vinyl compound having the formula R-CH= CH2, where R is a phenyl or substituted phenyl radical, 10-85 per cent of an alkyl acrylate and 5-60 per cent of an alkyl half-ester of an ethylene a ,b -dicarboxylic acid.  Polymerization is generally effected in the presence of an emulsifying agent and a peroxide catalyst. Specified vinyl compounds are styrene, p-chlorand p-methyl-styrene.  The acrylate preferably has 1-8 carbon atoms in the alkyl group and the half ester is preferably a secondary alkyl half ester having at least 4 carbon atoms in the alkyl group.  Specified are capryl acid maleate and the butyl, amyl, hexyl and heptyl half esters of maleic, fumaric, citraconic, and phenyl, ethyl and benzyl maleic acids.  In an example, a crude capryl maleate containing small amounts of dicapryl maleate and capryl alcohol is polymerized with styrene and ethyl acrylate, much of the latter two monomers being added over a period of 16-20 hours, the emulsion being at a temperature of 40 DEG  C. and in atmosphere of nitrogen.  Polymerization is completed by heating for 3 hours at 60-70 DEG  C.  The dispersions may be used as binders for pigment coatings on paper, textiles and leather, or may be deposited as films or coagulated Solutions of the copolymers, e.g. in alcohol-hydrocarbon mixtures, may be used as coatings or cements. The copolymers may be vulcanised by heating with polyreactive amines or alcohols, e.g. polyethylene amines, polyglycols, polyvinyl alcohol and melamine-formaldehyde resin.

Title: Skirt fringing apparatus
Inventor: REES ROBIN GORE
IPC: D03D5/00
Filed: 1967-07-20
Abstract: 1,142,900. Fringing fabrics. D. M. FORDE. 20 July, 1967 [20 July, 1966], No. 33490/67. Heading D1S. A teased fringe is produced on a piece of woven fabric by clamping the fabric in such a position that the portion to be fringed lies on a support 6 and subjecting this portion to the action of rotating brushes 28- which remove the weft threads therefrom without damaging the warp threads, the weft threads being progressively removed from the free edge of this portion towards the clamped edge thereof. Four longitudinal brushes 28, preferably having stainless steel bristles set into a hardwood backing, are mounted to bridge the peripheries between four equally spaced discs (27), Fig. 5 (not shown) on a shaft 18 rotatable by an electric motor 20. In operation, the fabric is positioned over supports 64, 6 with the portion to be fringed projecting downwardly from the support 6 in the machine. Handles 58 are depressed to move leyers 57 downwardly to rotate a shaft 54 and move cams 55 so that operating surfaces thereof exert downward pressure on wheels 50 to pull rods 42 downwardly, the wheels 50 being located between prongs 48 on the rods 42. Downward movement of the rods 42 lowers a clamping bar 7 against the action of springs 46 to clamp the fabric. The bar 7 and the support 6 are formed with rounded serrations to assist in gripping the fabric. The motor 20 is started by depressing a button 25 and when the brushes 28 are rotating at the required speed an operating handle 12 is moved downwardly towards the support 6. This causes levers 10 to pivot about a shaft 9 and to rotate arms 13 which thrust against links 14 to move carriage members 5 downwardly along inclined guide bars 4 against the action of springs 37. The rotating brushes 28 are thus brought into contact with the fabric portion to be fringed, the weft threads in the free edge of the fabric being loosened and removed before the brushes 28 are brought into contact with the remainder of the portion to be fringed. When the members 5 move towards the support 6, the arms 13 exert a restraining force upon links 37 to partly open a part-cylindrical guard 32 to enable the brushes 28 to act on the fabric. Threads removed from the fabric drop into a removable bin 61 and dust is drawn into collection bags 65 by a fan 66 operated by the motor 20.
