Title: Improvements in and relating to the liquid treatment of threads
Inventor: BURDETT KENNETH STANLEY
IPC: D01D10/04
Filed: 1953-10-07
Abstract: Aqueous treatment of artificial silk thread whilst it is advancing in helical turns round a pair of skew rollers is effected by applying the liquid to the surface of one of the rollers, and sraping the liquid from the surface of such roller close to the place where the turns of thread leave the roller so that liquid accumulates and flows on to the thread.  As shown in Fig. 1, freshly spun viscose thread 4 passes round skew rollers 6, 8, first round portions 5, 7 of reduced diameter, then round centre portions without any liquid treatment to allow regeneration to continue.  The thread is then led by thread guide 11 on to portions of 10, 12 greater diameter whereon it is subject to treatment with water from pipe 16, the water being removed by scraper 17 which hangs from supporting rod 24, (see also Fig. 2), the thread then being dried by heated roller 19.  Water removed by the scraper flows on to the threads as they leave the bottom roller and excess water is collected in pan 18.  The scraper 17 is preferably made of flexible material, e.g. rubber or polyethylene. Water may be played on to the roller from pipe 23, Fig. 2, instead of from pipe 16.  The pair of rollers may be divided into several treatment zones, each with its own liquid supply and scraper. <PICT:0756368/IV(a)/1> <PICT:0756368/IV(a)/2>ALSO:<PICT:0756368/IV(c)/1> <PICT:0756368/IV(c)/2> Aqueous treatment of a thread whilst it is advancing in helical turns round a pair of skew rollers is affected by applying the liquid to the surface of one of the rollers, and scraping the liquid from the surface of such roller close to the place where the turns of thread leave the roller so that a liquid accumulates and flows on to the thread.

Title: Improvements in and relating to vulcanised or sulphurised oil compositions
Filed: 1926-11-03
Abstract: 284,415. Waele, A. de. Nov. 3, 1926. Fats and fatty oils, sulphuretted.-Vulcanized oil compositions are obtained by treating with sulphur chloride, sulphur thiocyanate, dithiocyanogen, or like vulcanizing agents reacting energetically with glycerides of hydroxy unsaturated fatty acids, an ester of an unsaturated higher fatty acid in which one of the hydrogens of the fatty acid residue is substituted by an electro-negative atom or group which is less electro-negative than the hydroxyl group, e.g. chlorine or the acetyl, formyl, or carbonate group. Esters of other fatty acids, and oils, fats, or waxes, reacting with the vulcanizing agent, and fillers, diluents, accelerators, or retarding agents may also be present. Substances especially suited for treatment are acetylated castor oil and acetylated oxidized or blown oils. When coherent masses, e.g. printing rollers, are required, known means may be adopted for preventing the formation of bubbles or to eliminate gases or vapours formed, e.g. rotating moulds or substantially non-distensible moulds which are completely filled with the reaction mixture.

Patent GB-1089519-A (GB)
Title: Reinous organosilicon compositions
Inventor: BROWN DAVID ALBERT
IPC: C08G8/00
Filed: 1964-07-07
Abstract: A resinous composition suitable for the preparation of heat-resistant laminates, mouldings or coatings comprises (i) a precondensate obtained by a partial transesterification of an organic silicate and at least one polyhydroxy compound either or both of said silicate and said polyhydroxy compound containing aromatic groups and (ii) formaldehyde or a precursor thereof. (ii) may be hexamethylenetetramine which also serves to provide basic conditions for further condensation, and it may be present so as to provide 2 to 35% by wt. HCHO based on the precondensate. The composition may be stabilized at a pH from 5 to 6.5 by addition of an acid.  The composition may be prepared by reacting one molar equivalent of the silcate ester with 7.2 to 8.4 hydroxyl equivalents of the polyhydroxy compound. The composition may also contain a minor proportion of a monohydroxy compound (e.g. phenol, a - or b -naphthol) and also minor proportion of the tri- or tetrahydroxy compound, the major component being a dihydroxy compound, e.g. a dihydric phenol or diphenylol propane (Bisphenol-A).  Preferred silicate esters are tetra-ethyl and tetra-phenyl silicate.  The transesterification reaction may be carried on until 50-95% of the theoretical quantity of monohydroxy compound has been displaced from the silicate ester. It may be carried out in the presence of a catalyst (e.g. PbCO3) and in an inert solvent (e.g. methanol, isopropanol or methyl ethyl ketone). Examples relate to the preparation of laminates from glass fibre cloth and asbestos cloth.ALSO:Coatings which may be applied to asbestos, metal (e.g. iron or copper), paper, glass, silica, carbon and other heat resistant or porous materials comprise a resinous composition; (i) a precondensate obtained by partial transesterification of an organic silicate ester and at least one organic polyhydroxy compound either or both of said silicate and said polyhydroxy compound containing aromatic groups, together with (ii) formaldehyde or a pecursor thereof, especially hexamethylene tetramine.  Coatings may be applied by padding or impregnating the substrate or by hot dipping or spraying.  In an example a precondensate obtained by reacting diphenylolpropane with tetraethyl silicate in a molar ratio of 4:1 was partially cured with hexamethylenetetramine and dissolved in methyl ethyl ketone. This solution was applied to clean iron or copper wires or sheet by dipping or spraying.  The coated pieces were dried at 100 DEG C for 10 minutes and cured by heating at 200 DEG C for 30 minutes. Other examples relate to the coating of glass cloth and the preparation of laminates therefrom.

Abstract: 1494850 Duplicators MATHIAS BAUERLE GmbH 4 July 1975 [30 Sept 1974] 28257/75 Heading B6C  Masters 21 in a duplicating machine are fed from a stack through a removable treating unit 55 and into clamping means 56 on a two-speed master cylinder 1. A control shaft 4, via lever 14, controls the speed of a drive motor, and rotation of cylinder 1 with cam surfaces thereon causes movement of a wheel 69 to control contact of a feed roller train 19, 27, 29-31, 34-37, with blanket cylinder 2. Moving wheel 69 also controls, by another gear train, drive to conveyer rollers 51-53 which are automatically stopped when a master 21 has reached clamp 56. Synchronization of the opening of clamp 56 is achieved using a further cam surface 91 on cylinder 1 and a solenoid 121 which, when shaft 4 closes switch S 3 , pulls arm 119 so that rotation of a synchronous cam disc 128 pushes arm 119 against stop 116 and shifts pin 109 thus pivoting a lever 94 to open the clamp 56. When the master is fixed the cylinder is then run at a printing speed until solenoid 121 is again actuated by an operator. A switch 130 stops the machine after the last master 21 is fed.

Spray carburettors. - A spray tube b is arranged in proximity to a rotatable valve a which controls air entering at a<1> and is in communication with a nozzle c controlled by a needle valve e. The space n above the fuel in the float chamber m is in communication with the spray tube through an orifice b<1> and with the atmosphere through a conduit o. Air is thus drawn into the spray tube with the fuel. The reduction of pressure in the float chamber causes the fuel to flow thereto from the main tank. The needle valve e is lifted by the current of air acting upon a disc thereon and the lift is controlled by two relatively adjustable eccentric pins f, f<1> mounted in the throttle valve. The pin f<1> revolves in a larger circle than f and has some lead relatively to the pin f and serves to control the valve during light running; the pin f is for use when running under load.
