Title: Copolyamides
IPC: C08G69/34
Filed: 1970-06-11
Abstract: 1315369 Jointing E I DU PONT DE NEMOURS & CO 11 June 1970 [11 June 1969] 28298/70 Heading B3V [Also in Division C3] A melt condensed co-polyamide consists essentially of at least 3 different recurring polyamide repeat units and has an annealed heat of fusion of 5 to 18 calories/g., is quenchable to the amorphous state at a cooling rate of 100‹ C./minute and has an upper Tg in the amorphous state of less than 30‹ C.; in the copolymer (a) 20 to 100 mol. per cent of the NH groups are derived from a C 6-20  polymethylene diamine, (b) 5 to 65 mol. per cent of the carbonyl groups are derived from a dimer of a C 8-24  fatty acid, (c) 8 to 65 mol. per cent of the carbonyl groups are derived from a C 6-18  polymethylene diacid and (d) 18 to 65 of the carbonyl groups are derived from a different C 6-18  polymethylene diacid or a C 6-18  polymethylene omega-aminoacid. Small amounts (insufficient to interfere with the adhesive properties) of other monomers may be used, e.g. diethylene triamine, branched alkylene diamines, diacids or aminoacids, terephthalic acidorp-aminocyclohexyl-bis-methane. In the examples acetic acid and a silicone antifoam agent are included in the polymerization recipes. The polymers are useful as adhesives, especially for side-lapped seams in tins but also for plastics, leather, wood and glass. They may be compounded with fillers, dyes or polyfunctional cross linking agents. Metal to metal adhesives.-When using the adhesives in the manufacture of metal tins with side-lapped seams it is preferred that the metal is precoated with an organic lacquer or enamel, e.g. the epoxy-phenolic composition of French Specification 1,492,346 or a proprietary polybutadiene composition, and that the adhesive polyamide has 10 to 100-10<SP>-6</SP> equivalents/g. of excess amine over carboxyl acids and contain some secondary amine groups, e.g. from 1% of diethylene triamine. Examples illustrate the use of 5-mil. films of the adhesive polymers to unite tin-free steel coated with a commerical epoxy-phenolic primer by heating at 20 p.s.i. and 300‹ C. for 10 seconds and rapid quenching. Reference has been directed by the Comptroller to Specification 1,000,216.

Patent GB-1078462-A (GB)
Title: Method of manufacture of fashioned knitted garments, machine for carrying out this method and garment obtained by this method
IPC: D04B1/24
Filed: 1964-07-10
Abstract: Undergarments, such as mens' pants or vests, swimsuits or other shaped articles having part tubular portions are knitted on a circular machine which produces the tubular portion by continuous rotary knitting and also produces shaped portions by reciprocatory knitting.  In a two feed machine having the knitting stations diametrically opposed the tubular portion is formed by knitting on all of the needles of the machine at both knitting stations.  Shaped portions are then produced by reciprocatory knitting on the needles of each half of the machine or on other divided groups of needles, the shaping being achieved by casting loops off the needles as they are rendered inoperative and subsequently forming fresh loops on them when they are reintroduced.  In addition pouches may be formed in the garment during reciprocatory knitting by narrowing and widening effected by rendering the end needles when they are rendered inoperative. The edges of the garments are subsequently seamed to prevent them unravelling.  The machine for producing the fabric garments comprises in one embodiment, a two feed machine in which the needles are capable of being elevated or lowered into one or more of four guide channels for the needle butts in which they occupy a high inoperative position with the loops on their shanks, an intermediate position in which the loops are positioned on the shanks beneath the latches, knitting position and a lowered inoperative position on which the needles reside after having cast off their loops.  The movement of the needles from one channel to the next or another channel is achieved by narrowing and widening pickers during the shaping operations and also by cams which selectively guide groups or individual needles into or out of their operative and inoperative positions.  In addition splicing mechanism is provided for reinforcing portions of the fabric garments and the reinforcing area control may be achieved by either needle selection on which needles are raised to take both ground and reinforcing yarns or the reinforcing yarn guide may be swung to wrap its yarn around and feed it to selected needles. The garments may be knitted in string form separated by separating courses each successive garment being a mirror image of the preceding garment, the garments being separated after removal from the machine stitched across the edges where required to secure them together and the edges trimmed and secured.

Abstract: 757,222. Control of D.C. motors; controllers TRIX VEREINIGTE SPIELWARENFABRIKEN GES. Oct. 19, 1953, No. 28821/53. Class 38(3) [Also in Group XV] A reversible toy vehicle is supplied from a transformer 7 having a secondary winding 6 co-operating with wiper arms 3, 4, connected to a rectifier 25. A reversing device is fixed to the arms 3, 4, and comprises arms 14, 15 formed of non-conducting material and carrying contacts which co-operate with conductive segments 18-24. For forward travel of the vehicle, the arm 4 is moved along the winding 6 and the contacts 27-30 on the arm 14 co-operate with a number of the fixed segments so that the rectifier 25 is connected to supply current to the lines 26 for driving the vehicle in the proper sense. Movement of the arm 4 towards the left increases the voltage supplied to the vehicle. When the arm 3 traverses the winding 6 the reverser arm 15 is rendered operative and the vehicle is adjusted for backward operation. In the "off". position of the arms 3 and 4, a fixed voltage is supplied to the vehicle for auxiliary operations by depressing a switch 36, the current passing through detached . contact segments 34 35, and movable contacts 31, 32. In a modification the reverser takes the form of a cam disc fixed to the arms 3, 4 and co-operating with a spring arm having a movable contact adapted alternatively to engage two fixed contacts for travel in either direction (Fig. 3, not shown). A pointer may be fixed to the arms 3, 4 for indicating the direction of travel and the speed of the vehicle, and pilot lamps may be provided. The rotatable arms 3, 4, may be replaced by a longitudinal slider carrying two contact fingers (Fig. 4, not shown). Instead of the transformer 7, the vehicle may be supplied through other forms of transformers or through a resistor. For multivehicle operation, the transformer may have several secondary windings arranged on different limbs.

Title: Improvements in or relating to the manufacture of sodium thiosulphate
IPC: C01B17/64
Filed: 1930-09-26
Abstract: A process for producing alkali, especially sodium, thiosulphates by heating sulphur and calcium sulphite with an aqueous solution of an alkali sulphate is characterized in that a substance having a basic reaction is present.  Alkali or alkaline-earth bases or alkali salts of weak acids, as carbonates, sulphites, or sulphides, are specified. The solution obtained may be neutralized in certain cases by adding say alkali bisulphite. Polysulphides present in small quantities are also thereby converted in thiosulphate.  Alkali thiosulphate may be crystallized from the solution after separation of calcium sulphate. Reference is made to a similar process wherein there is no addition of a substance having a basic reaction.

Abstract: 289,121. Beeston, W. G. Jan. 15, 1927. Annealing-furnaces: muffle furnaces; charges, conveying and cooling.-In a furnace for annealing metal sheets in an inert atmosphere, of the kind in which the sheets 11<a> are carried by a conveyer 9 through a muffle - heated chamber 6 and then through a cooling extension 1, the chamber 6 and a superposed heating flue 5 are enclosed in a metal tube 1<a> lined with refractory material 2 and connected to the extension 1 at 1<c>. The flue 5 receives, at one end, hot gases from a gas or coal fired furnace 3 through a lateral passage 4, and communicates at the other end with a chimney 7. The space 8 below the muf33e 6 forms, with a similar space in the lower part of the extension 1, a continuous passage for the return run of the conveyer 9, a non-oxidizing atmosphere, at a pressure slightly above atmospheric, being maintained both in this passage and in the muffle 6.
