Title: Continuous process for treating cellulosic fabrics with formaldehyde
Filed: 1962-07-30
Abstract: Cellulosic fabrics are creaseproofed by treating them with an aqueous medium until they contain 10-100% by weight of water and then treating them with a solution of formaldehyde in a dehydrating medium, i.e. a medium which is itself a dehydrating agent or is an aqueous solution of a dehydrating agent containing at most 50% by weight of water.  The dehydrating medium may be glacial acetic acid or a calcium chloride solution of from 50% by weight concentration up to saturation.  The fabric may first be padded to 10-100% by weight pick up with an aqueous solution of a strong acid or a salt of a weak base with a strong acid, e.g. phosphoric, hydrochloric, hydrobromic, sulphuric, trichloroacetic, formic or toluene sulphonic acid, ammonium chloride or ammonium sulphate, which preferably has an acid strength varying between 0.01 and 20% by weight and may then substantially immediately be treated with the formaldehyde solution in the dehydrating medium which may contain 0.01-2% by weight of acid.  Alternatively the fabric may first be padded to a 10-100% by weight pick up with water or an aqueous solution containing 0.1-1% by weight of an anionic, cationic or narionic wetting agent numerous examples of which are given and then impregnated substantially immediately with the formaldehyde solution in the dehydrating medium which may contain 0.01-20% by weight of a strong acid.  Before or after the formaldehyde treatment the fabric may be treated with 2-18% by weight of a crease-proofing resin, e.g. dimethylol urea, dimethyl ether of urea-formaldehyde resin, trimethylol melamine, methylated trimethylol melamine, tetrahydro-5-hydroxy-2(1H)-pyrimidone-formaldehyde, cyclic ethylene urea-formaldehyde, urea formaldehyde, dimethylol ethyl triazone, butediene diepoxide, bisphenol-A epichlorhydrin, 1,4 bis (2,3 epoxy-propoxy) benzene, 1,3-bis (2,3-epoxy propoxy) octane and ethylene glycol diglycidyl ether resins, which may be cured by heating to 178 DEG C. for 1 1/2 minutes.  Fabrics comprising cotton, linen, hemp, jute, ramie, sisal, viscose rayon, cuprammonium rayon, cellulose acetate, cellulose acetate-propionate, cellulose acetate-butyrate or ethyl cellulose fibres alone or in admixture with nylon, polyacrylonitrile or polyester fibres may be treated.

Abstract: 942,690. Diaphragm pumps. UNION CARBIDE CORPORATION. Aug. 15, 1961, No. 29364/61. Headings F1A and FIN. In a fluid-pressure actuated diaphragm pump or pulsator, for liquids or gases, comprising an actuating chamber 12, Fig. 5, and a pumping chamber 14 separated by a diaphragm 10, fluid e.g. compressed air, enters actuating chamber 12 until diaphragm 10 flexes to uncover an exhaust port 36 whereupon air escapes until the diaphragm returns and closes the exhaust port again. The pump inlet pressure assists in moving the diaphragm to close the exhaust port. The diaphragm may be spring-biased away from the exhaust port. In another embodiment, Fig. 7, actuating chamber 12 is separated from pumping chamber 14 by a fluid contained between two diaphragms 10 and 50, the rate of pumping being determined by the size of a passage 62 between the diaphragms. In a pulsator, Fig. 6, chamber 14 is provided with a single port 26 communicating with a cylinder 28 containing a column of liquid, e.g. mercury, and a fluid, e.g. air. A baffle 38 is provided to prevent the stream of liquid through port 26 from breaking the surface.

Title: Method and apparatus for carrying out the sub-halide distillation process for the recovery of aluminium
IPC: C22B21/00
Filed: 1962-08-01
Abstract: In a subhalide distillation process for the extraction of aluminium from aluminium containing material at least a part of the surface of graphite or other carbon material in the apparatus in which the process is carried out, is protected from attack by the gaseous monohalide by establishing a film of gaseous trihalide, or a gas which is inert in relation to the process, over said surface.  The trihalide is preferably supplied through a plurality of orifices in the surface (e.g. the face of the graphite electrode), but may be supplied through a conduit which directs a stream of the trihalide on to the surface to be protected. When using graphite electrodes for passing an electric current for heating purposes these are preferably recessed into the walls of the converter.

Title: Improvements relating to flexible couplings for pipes
Inventor: HAUGHTON DONALD STUART
IPC: B29C49/22
Filed: 1959-08-29
Abstract: 952,738. Moulding flexible pipe couplings. DUNLOP RUBBER CO. Ltd. July 19, 1960 [Aug. 29, 1959], No. 29569/59. Heading B5A. A flexible pipe coupling is made by forming a length of mouldable tube 4 with at least two radially inextensible portions, each of which forms a supported portion of the tube, the portions extending axially and circumferentially of the tube and lying spaced apart from each other by a radially extensible portion of the tube and also from the ends of the tube, expanding the radially extensible portion of the tube between the supported portions and moulding the ends of the tube into annular flanges 8, the expansion of the tube between the supported portions being effected at least in part by applying a differential fluid pressure between the interior and exterior of the tube. The tube 4 is formed from mouldable material which remains flexible in its final state such as natural or synthetic rubber or a thermoplastic having a reinforcement 5 of cord or fabric which may be textile or metallic. It is further strengthened at the supports by the incorporation of encircling non-extensible bands 6. In the embodiment described, the apparatus used is a three-part mould (Fig. 4) comprising an axially split segmental hollow cylindrical member 20 and two end plates 30, 31. One of the end plates, 31, is secured to a mould core 32, the two components forming a joint mould member, while the other end plate, 30, has an inlet 33 connecting a fluid pressure supply line to perforations 34 in the core 32. Member 20 is provided with one or more depressions 21 to form the corrugations of the coupling and with recesses 22 to form the flanges 8. A tube 4, of unvulcanised rubber, for example, is placed around the core 32 and the mould then assembled, the end plates 30, 31 forcing the end portions of the tube 4 which have been turned outwards by swaging into the recesses 22 and axially compressing the tube between the flanges to force the unsupported regions into the depressions 21. The mould is then heated and subjected to internal steam or air pressure. In an alternative apparatus, the fluid pressure is applied by an inflatable liner. A tube with preformed expanded portions cut from a length of corrugated tubing may be used in place of a cylindrical tube and the flanges 8 formed as above, the tubing being cut at two peaks with at least one peak in between them. Annular rings of unvulcanised rubber may be positioned between the outwardly directed end portions of the tube 4 and the end plates 30, 31 so that during moulding they become incorporated into the flanges 8.

Abstract: 159,609. Palmer, H. J., and Telephone Manufacturing Co., Ltd. Dec. 2, 1919. Microphones.-Relates to microphones of the type in which the sound-receiving diaphragm and the movable electrode are located on opposite sides of one wall of the carbon cup containing the resistance granules. According to the invention, the movable electrode H, which is carried by a pin J secured by a set-pin L<1> to a bush L mounted on the sound-receiving diaphragm C, is also secured to a resilient support, such as a flexible mica diaphragm G. The diaphragm G is held between the rim of the carbon cup D, containing the granules M, and an ebonite ring F clamped to the base of the brass casing B; it also serves to close the open face of the cup. The opening in the end of the cup next to the diaphragm C is covered by a felt dish O, which also functions as a spring damper. An insulated spring may be used in place of the resilient diaphragm G; or the movable electrode H may be connected to the sound-receiving diaphragm C by pivoted links. By this construction, violent sound-impacts on the microphone tend to separate the resistance granules rather than to pack them.
