Patent GB-546722-A (GB)
Title: Starting of supercharged compression-ignition engines
IPC: F02B3/00
Filed: 1941-04-05
Abstract: 546,722. Starting. SANDERS, A. F., and FOWLER & CO. (LEEDS), Ltd., J. April 5, 1941, No. 4568. [Class 7 (v)] A compression-ignition engine having a super-charger 13 directly coupled to the engine is started by means of electric ignition and a petrol or like carburettor 33 connected with the induction pipe 19 (between the supercharger chamber 18 and the engine) through an automatic valve 66 which can open when a valve between the chamber 18 and the carburettor connection is closed, and vice versa. As shown the chamber 18 is connected by the induction pipe 19 to an admission valve 20 on the engine cylinder 11, as in Specification 539,423. Fuel is normally injected by a pump 26 into a combustion chamber 21 having a sparking plug 23 for starting. A spring-pressed piston 43 in the wall of the chamber 18 actuates a bell-crank 45 connected at 47 to the petrol cock 35 of the carburettor 33, at 49 to the ignition switch 39, at 51 to an arm 52 of disc valve 30 between the chamber 18 and the induction pipe, and at 54 to a lever 55 for moving the control rod 28 of the fuel pump 26 to the inoperative position. At starting, with the valve 30 closed, the engine is turned and mixture drawn in from the carburetter 33 through the automatic valve 66 in the pipe 32 is ignited by the plug 23 until the pressure in the chamber 18 is sufficient to actuate the piston 43, opening the valve 30, cutting off the ignition and the carburettor and allowing the fuel pump 26 to come into action. In modifications, the valve 30 is operated manually by a rod connected to the arm 52, or is replaced by a poppet valve closed by a' light spring and opened by a piston exposed to the pressure in the chamber 18. The control rod 28 of the fuel pump may also be actuated from another piston actuated by the pressure in the chamber 18, a bevelled disc on the piston rod bearing on the end of the control rod. Specification 324,378, [Class 7 (v)], also is referred to.

Filed: 1941-04-09
Abstract: 548,560. Coating surfaces; polyamide coating compositions. DU PONT DE NEMOURS & CO., E. I. April 9, 1941, No. 4730. Convention date, April 9, 1940. [Class 95] [Also in Groups IV and VIII] A coating process comprises applying to the surface of an object a dispersion of particles comprising a fibre-forming synthetic linear polyamide in a medium which is a latent solvent for the polyamide, dissolving the polyamide in the latent solvent by heating, and resolidifying the polyamide in the form of a continuous coating on the object by the simultaneous evaporative removal of at least the major portion of said medium. The resolidified polyamide may then be reheated to a temperature above its melting point, and then rapidly cooled, e.g. by quenching. The heat may be applied by baking in an oven, by pressing with a hot iron or in a hot press, by heating in contact with molten metal, e.g. Wood's metal, by the use of a high frequency electric field, or by infra-red radiation. Specified dispersion media' include benzyl alcohol, furfuryl alcohol, ethylene glycol with or without water, di-(#-hydroxyethyl) ether and formamide. The term polyamides includes polyester-amides, and the dispersions may include dispersing agents, plasticizers, waxes, resins, cellulose derivatives, rubber, powdered metals, pigments, anti-oxidants and ultra-violet light opacifiers. Examples are given. Specifications 461,256, [Group XL], and 544,715, [Group IV], and U.S.A. Specifications 2,071,250, 2,130,523 and 2,130,948 are referred to.

Patent GB-581897-A (GB)
Title: Improvements in or relating to the manufacture of polymeric substances containing fatty oil acid radicals
IPC: C08F8/00
Filed: 1943-03-25
Abstract: Polymeric substances containing fatty oil acid radicles are produced by heating a polymeric acrylic or a-methacrylic acid ester with a non-hydroxylated fatty-oil acid partial ester of a polyhydric alcohol which ester contains one or more free hydroxyl groups, the number depending upon the molecular weight of the polymeric ester and being such that gelation of the mixture does not occur before homogeneity is obtained (see Group IV).  The partial ester may contain radicles of more than one fatty oil acid and is preferably obtained by an ester-interchange reaction between a drying-oil and a polyhydric alcohol in the presence of an alcoholysis catalyst, e.g., litharge, zinc oxide or calcium oxide.  In an example, technical diglycerides of linseed oil are prepared by heating alkali-refined linseed oil with glycerine in the presence of calcium linoleate.  Films prepared from a xylol solution of the product obtained by heating the diglycerides with polymethylmethacrylate and calcium linoleate dried rapidly without the addition of driers.  Specifications 461,979 and 506,666, [both in Group IV], and U.S.A.  Specifications 2,109,877 and 2,160,532 are referred to.ALSO:Polymeric substances containing fatty oil acid radicals are produced by heating a polymeric acrylic or a -methacrylic acid ester with a non-hydroxylated fatty-oil acid partial ester of a polyhydric alcohol which ester contains one or more free hydroxyl groups, the number depending upon the molecular weight of the polymeric ester and being such that gelation of the mixture does not occur before homogeneity is obtained.  With polymeric esters of high molecular weight not more than one free hydroxyl group must be present in the partial ester.  The progress of the reaction and the relative proportions in which the two ingredients are employed also to some extent depend upon the molecular weight of the polymeric ester.  The reaction may be carried out in the presence or the absence of a solvent.  The partial ester may contain radicals of more than one fatty-oil acid, and is preferably obtained by an ester-interchange reaction between a drying oil and a polyhydric alcohol in the presence of an alcoholysis catalyst, e.g. litharge, zinc oxide or calcium oxide (see Group III). These catalysts may also be used in the heating process of the invention.  In an example, polymethyl methacrylate is heated with calcium linoleate and diglycerides of linseed oil, obtained by heating alkali-refined linseed oil with glycerine in the presence of calcium linoleate.

Abstract: 1458055 Grinding FRIED KRUPP HUTTENWERKE AG 4 Feb 1974 [2 March 1973] 05110/74 Heading B3D A process for re-grinding a roller 4 which has become unevenly heated along its overall length by a rolling process comprises spraying coolant on the roller during re-grinding simultaneously along the total length of the roller, the temperature of the roller during re-grinding being equalized in dependence upon the degree of heating at different points along the roller by supplying different volumes of coolant to individual areas of the roller such that at least on completion of re-grinding the temperature is substantially uniform along the entire length of the roller. In a device for carrying out the process, the roller 4, which has worn concave and has a higher temperature midway along its length than at its ends, is supported by bearings 2 in a stand 1 and is rotated by a drive 5. A grinding assembly 7 has a wheel 6 which is adjustable towards the roller along slideways 9 on a slide 10 movable along a bed 11 parallel to the axis of the roller. A pipe 12 disposed parallel to the roller is secured by brackets 15, 16 to the frame 1 and is supplied with coolant through a conduit 17 and valve 18. The pipe 12 is provided with spraying nozzles 14 along its length, the nozzles being spaced more closely along the middle of the pipe so as to effect increased cooling of the central part of the roller.
