Title: Electronic switching circuit
Inventor: MILLER GEORGE BERTRAM
IPC: H03K17/28
Filed: 1960-09-30
Abstract: 930,115. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 29, 1961 [Sept. 30, 1960], No. 33644/60. Class 40 (6). In a switching circuit comprising an electronic switch having an electrically-operated switching device (e.g. a relay) connected in its output circuit, the output circuit is connected back to the input of the electronic switch through a series connected capacitor and diode arranged to delay or prolong operation of the electrically-operated switching device. A circuit for delaying the operation of a relay L comprises a transistor switch T having a capacitor C and a diode D1 connected in series in a feed-back path between collector and base. On switching on transistor T, capacitor provides feed-back to delay operation of the relay. On switching off the diode prevents feed-back to give a quick release. Fast operate and slow release of the relay may be obtained by reversing the polarity of the diode or by using an NPN transister. For high pulse repetition frequencies a further diode D2 may be connected in series with a resistor R to provide a charge on discharge path for the capacitor when D1 is in its high-resistance condition.

Abstract: 1,029,135. Laminates. AVON RUBBER CO. Ltd. Oct. 11, 1963 [Sept. 4, 1962], No. 33861/62. Heading B5N. Vulcanizable substantially saturated polymeric material, e.g. compositions containing butyl rubber, or a rubber comprising a terpolymer of ethylene, propylene and a non- conjugated diene, is bonded to vulcanizable relatively unsaturated polymeric material such as natural rubber, oil-extended or other styrenebutadiene rubber or cis-1,4-polybutadiene, by interposing a layer or composition containing chlorobutyl rubber and a chloroprene polymer and vulcanizing the assembly.

Trash is removed from the underside of a carding engine by mechanically conveying it to a suction chamber through which air is drawn from suction nozzles mounted in the vicinity of fly-producing parts of the machine. A conveying worm may be used to remove the trash or a single conveyer belt may extend throughout the length of the machine undercasing, or two conveyer belts may be mounted to deliver to opposite ends of the machine from beneath the doffer and swift, or, as shown, individual belts 6, 13, 17 may deliver to air chambers 9, 15, 18 from beneath the swift, doffer and taker-in. The air chambers 9, 15, 18 receive air through pipes 11 from suction nozzles 12, and from the air chambers the trash delivered by the conveyer belts is carried by the air through outlets 10 to a filter system. Rollers that rest upon the conveyer belts at the entrances to the air chambers seal off the chambers from the undercasing and air within the chambers is directed to flow over the rollers and extremities of the belts. The latter may have transversely disposed ribs and rubber strips secured to the machine frame may bear upon the edges of the upper run of the belt. Specification 872,288 is referred to.

Abstract: 1,127,426. Metal oxide coatings; coating apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 July, 1966 [31 July, 1965], No. 33960/66, Headings B2K and B2L. A method of coating the inner surface of a tubular article 4, made of glass, quartz or like insulating material with a substantially continuous protective layer 6 of a metal oxide having a higher melting point than the material of the tubular article and substantially more resistant than that material of the action of metal vapours, comprises melting the coating material in finely divided form on said surface, by heat generated by an electric discharge through gas, produced within the tubular article by a high frequency induction field. In Fig. 2, a tube 10, the inner surface of which is coated with a layer 6 of a coating suspension is supported by a tubular member 11 and surrounded by a jacket 9, the assembly being vertically displaceable, gas being supplied through 4 and exhausted through 5, the tube being initially placed within the heating furnace 7 and then moved to lie within the field of an induction 8. In a modification of the apparatus (Fig. 4, not shown) means are provided for introducing the finely divided coating material with the gas whilst the tube is kept in rapid rotation, the particles being deposited on the inner wall of the tube in molten state. Specified metal oxides are alumina, zirconium oxide calcium oxide, magnesia and beryllium oxide. The coating material may be sucked up the tube in the form of an alcohol suspension containing nitro cellulose, excess material being removed prior to heating. In a modification of the method, a first coating of insulating material having a coefficient of expansion between the coefficient of expansion of the tube and of the metal oxide coating may be applied to the tube prior to the metal oxide coating.

Title: Method and apparatus for producing designs on fabrics
IPC: B41F19/02

Abstract: 868,458. Producing patterns on fabrics. UNITED MERCHANTS & MANUFACTURERS Inc. Oct. 27, 1958 [Sept. 9, 1958], No. 34293/58. Class 100(2) A method of producing a design on fabric comprises stamping the fabric by passing it in a moistened condition through the nip formed by a heated engraved roller rotating in unison and co-acting with a plain-surfaced roller which has not been "run in". The fabric 21 e.g. cotton, regenerated cellulose, cellulose acetate, nylon, "Dacron" (Registered Trade Mark) and other natural or man-made fibre fabrics, is damped with water so that it has a moisture content ranging from 5 % to 15 % and is then passed between an engraved steel embossing roller 18 and a smooth surfaced counter roller 19. The roller 19 is formed of compressed paper, wool, cotton or a composition of cotton and wool and has a smooth, undeformed outer surface since it has not been "run in" in contact with the roller 18. The roller 18 is heated to a temperature of from 360‹F. to 450 ‹F. and bears on the counter roller with a pressure of from 50 1b. per square inch to 525 lb. per square inch. Shallow depressions are formed in the fabric 21 by the relief design on the roller 18. After passing between the rollers the fabric exhibits a visually discernible design owing to the high gloss of the stamped portions contrasted with the rough surface of the unstamped part. If the fabric is then dyed the stamped design will show up as a pale shade against a darker ground, Fig. 2, owing to the smaller affinity of the stamped portions to the dye.

Title: Manufacture of anthraquinone derivatives
IPC: C09B5/10
Filed: 1935-12-11
Abstract: An amino-isothiazolanthrone or an amino-anthra-di-isothiazole is treated with an acylating agent of which the acyl group is the residue of an anthraquinone carboxylic acid which does not contain a nitrogenous group in the heteronucleus (i.e. the ring not containing the carboxyl group).  A product specified is 4-(1<1>-anthraquinonoyl)-amino-1.9-isothiazolanthrone. Solvents, acid binding agents, or catalysts may be used, in an open vessel or under pressure.  The products may be converted into leuco-derivatives.  The products are intermediates or dyes which produce fast, strong dyeings and printings on vegetable fibres.  In examples, 5-amino-1.9-isothiazolanthrone is condensed with (1) anthraquinone-2 (or 1)-carboxylic acid chloride; (2) 1-chloroanthraquinone-2-carboxylic acid chloride; (3) 1-amino (or benzoylamino) anthraquinone-2-carboxylic acid chloride; (4) 4.8-diamino-1.9.5.-10-anthra-diisothiazole is condensed with anthraquinone-2-carboxylic acid chloride; (5) 4 - amino - 1.9 - isothiazolanthrone is condensed with 1-aminoanthraquinone-2-carboxylic acid chloride; (6) anthraquinone-2-carboxylic acid chloride may be condensed with 4 (or 8 or 6)-amino-1.9-isothiazolanthrone, or 5-amino-8-methoxy- or 5-amino-8-chloro-1.9-isothiazolanthrone.  Two examples are given of the dyeing of cotton yellow shades using the dyestuff produced in (1) above.  4.8 - Diamino - 1.9.5.10 - anthra-di-isothiazole is prepared by sulphonating 1.5-diaminoanthraquinone with fuming sulphuric acid in presence of boric acid, and heating the sodium salt of the 1.5-diaminoanthraquinone-4.8-disulphonic acid so obtained with sodium sulphide, sulphur and ammonia for 10 hours at 100 DEG  C.  The Provisional Specification refers to treating the products with sulphuric acid, an aldehyde such as formaldehyde or a halogenating agent to yield further valuable products.
