Title: Improvements relating to electrical relays
IPC: H01H47/04
Filed: 1942-10-19
Abstract: 560,870. Electromagnetic relays. TOMLINSON, A. V. (Union Switch & Signal Co.). Oct. 19, 1942, No. 14615. [Class 38 (v)] \ In a relay suitable for use as a railway track relay and having a " release " value only slightly less than its " pick up " value, the armature 12, pivoted at 13 co-operates with an E-shaped magnet 8 having three windings 9, 10, 11 and actuates contacts 17, 18 which, during " pick up," substitute the winding 10 for the winding 11 and so decrease the torque arm of the magnetic forces acting on the armature. In the " pick-up " position shown, the windings 9, 10 are energized and their fluxes assist each other in the legs 5, 6 but oppose each other in the leg 7. When a train shunts the rails 1, 1a and thus also the windings 9, 10, the armature is quickly released. When the train leaves the section, windings 9, 11 are energized and exert attraction on the armature from legs 6, 7. The growth of flux in leg 7 is, however, delayed by a copper ferrule 14 thereby delaying the " pick-up." The contact 17 is adapted to " make " before the contact 18 " breaks."

Title: Improvements in the production of thermoplastic polymeric materials
Inventor: FENDLEY JOHN ATTON
IPC: C08F279/02
Filed: 1957-05-08
Abstract: Graft polymers are prepared by polymerizing 1 to 9 parts of methyl methacrylate, or 1-9 parts of a mixture of methyl methacrylate with up to its own weight of a monoethylenically unsaturated compound(s), in the presence of a stable aqueous dispersion containing 1 part of a rubbery copolymer obtained by polymerizing a mixture of butadiene with up to its own weight of methyl methacrylate.  The rubbery copolymer may be obtained by polymerizing a mixture of 70-80% butadiene and 20-30% methyl methacrylate to at least 90% conversion, and preferably to completion.  A bifunctional monomeric material, e.g. divinyl benzene or glycol dimethacrylate may be present in amount from 0.1 to 5%.  The methyl methacrylate comonomers may be acrylonitrile, methacrylonitrile, methyl or ethyl acrylate and ethyl, propyl or butyl methacrylate, and the grafting may take place in the presence of organic peroxide or hydroperoxide catalysts or azo catalysts or modifiers such as aliphatic mercaptans, and organic polysulphides, the usual emulsifying agents, fillers, pigments and stabilizers.  It is preferred to feed a previously prepared stable aqueous dispersion of the rubbery polymer and the monomer continuously into a reaction vessel and to remove the polymerized material continuously from the vessel at a point remote from the point of entry, the rate of flow of the dispersion being such as to allow a residence time of from 5-10 times the time for the polymerization to go to completion in the absence of continuously added fresh reactants.  This rate of flow may be controlled so that the heat continuously liberated by the polymerizing material is absorbed by the dispersion fed in, thus maintaining the reaction temperature constant.  The products may be shaped, or moulded into articles.

Patent GB-496248-A (GB)
Title: Pancreas-derived product and process of producing it
IPC: H02K21/38
Filed: 1937-05-28
Abstract: A fat-metabolism controlling substance is obtained from pancreas by extracting pancreas with a solvent for the substance, e.g. 60 per cent alcohol, removing the solvent from the extract and separating the bulk of the insulin from the extract by the action of a solvent in which insulin and the desired substance are differently soluble. Pancreas is extracted by adding alcohol of about 95 per cent strength in sufficient quantity to provide with the water content of the pancreas a concentration of about 60 per cent, the pH being about 4. The extract is then either evaporated to dryness and extracted with a fat solvent or the alcohol is driven off, whereby fat comes out of solution and the water solution is dried.  The fat free residue of either process is taken up in water (or adjusted in aqueous solution) to contain 10 per cent solids and is then saturated with sodium chloride, whereby a precipitate is formed which is separated and taken up in alcohol of about 90 per cent strength.  One and a half volumes of ethyl ether is added which produces a precipitate of the fat-metabolism controlling substance, the insulin remaining in solution.  The dried precipitate may be used as such or may be further purified by taking up in water and adjusting to pH of 4 to 5,5, at which pH most of the insulin is insoluble.  The precipitate is removed and the remaining liquid may be administered orally as such or may be evaporated to dryness. Specifications 203,778, 209,766, and 212,238, [all in Class 81 (i)], are referred to.

Filed: 1961-04-25
Abstract: 938,550. Converting. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 25, 1961 [April 28, 1960], No. 14914/61. Class 38 (2). [Also in Group XL (c)] In a D.C. to D.C. converter comprising a pushpull transistor oscillator which includes transistors 1, 2, and a transformer 3, with a rectifier connected to the transformer output winding 5, feedback to the transistor base electrodes is derived from this output winding. As shown the rectifier is a voltage doubler circuit comprising the emitter-base circuit of the transistor 1, a capacitor 8, a diode 7, and a capacitor 9. When transistor 1 conducts a feedback circuit is completed from the winding 5, a resistor 11 and emitter-base circuit of transistor 1 to charge the capacitor 8. When either the transistor or the transformer core saturates the voltage in winding 5 reverses cutting off transistor 1. The capacitor 8 then discharges through the emitter base circuit of transistor 2 causing this transistor to conduct until saturation when the cycle is repeated. In a modification (Fig. 2, not shown) to avoid overloading the emitter-base circuit of transistor 1, the base is connected to the capacitor 8 through a diode and a resistor is connected between the base and emitter electrodes. Also a diode replaces the resistor 11 and a surge protection capacitor shunts the winding 5. A bridge rectifier circuit whose arms comprise the two emitter-base circuits and two diodes, and which does not multiply the voltage is also described (Fig. 3, not shown). Specifications 769,445, 797,332 and 859,655 are referred to.

Abstract: 653,766. Coated sheet materials. BAKELITE CORPORATION. June 4, 1948, No. 15189. Convention date, June 26, 1947. [Class 140] [Also in Group XVI] A sheet suitable for the production of a matrix for moulding printing plates, sound records, counters and the like, has a base composed of cellulosic fibres and a heat-hardenable synthetic resin, and a surface-coating of a water-soluble polyvinyl alcohol or a watersoluble cellulose ether, or both. As cellulose ethers are mentioned water-soluble partially alkylated cellulose ethers, particularly methyl and ethyl cellulose; water-soluble hydroxyalkyl cellulose ethers, particularly hydroxyethyl cellulose ; water - soluble alkoxyalkyl ethers, such as beta-ethoxyethyl cellulose and gamma-methoxy propyl cellulose; and the water-soluble alkali salts and ammonium salt of cellulose , glycollic acid. The base material may be given a matt surface prior to coating, or such a surface may be obtained by mixing comminuted thermosetting moulding material with the aqueous solution of polyvinyl alcohol or cellulose ether. The coating, which should be thin, so as not to level off the sheet's rough, matt surface, is preferably dried at a temperature between 5 and 38 C. Matrices may be prepared from the sheets by moulding them against a rigid pattern by heat and pressure, which advances the synthetic resin to the insoluble and infusible condition. The presence of the coating facilitates the release of the matrix from the mould. Specification 505,579 is referred to.

Abstract: 933,836. Rolling tubes. TUBEWRIGHTS Ltd. April 27, 1962 [April 27, 1961], No. 15288/61. Class 83 (4). A method of hot shaping an end of a tube, shaft or bar comprising holding the tube stationary and rotating a work head to produce the required shape on the end of the tube &c. A number of tubes 14 are gravity fed down a rack 12 to a pair of steps 15 and are singly lifted by a pair of thrust mechanisms 16, operated by electrohydraulic thrust units 49, on to a cradle comprising a pair of idler rolls 17; the unit also simultaneously unloads a heated tube on to a bed 11. The racks 12 comprise longitudinal and transverse rails 40, 41 welded to vertical posts 42. The two thrust mechanisms 16 are located and spaced apart at the lower end of the feed rack 12 and each comprises a pair of spaced shaped plates 45 fitted between a pair of rails 40 and connected together at one end by a bridge piece 46 and at the other by a tube 47 pivotally mounted on a stub axle 48. Whilst on the rolls 17 one end of the tube is heated by a multi-jet oxyacetylene torch 18 supplied by bottle sets 19, 20, 21 or by an induction heating coil. After a pre-set time the heated tube is unloaded by the thrust mechanisms 16 on to rollers 25 situated on the bed 11 one of which is motor driven and is fed towards a spinner head 52. Feeding of the tube contacts a stop 57 which closes a microswitch on a locker bracket 58 to stop the motorised roller and cause a number of vices 26 to clamp the tube and simultaneously causes the stop 57 to swing out of the path of the tube. Swinging of the stop switches an hydraulic cylinder into operation which moves the gripped tube into contact with the rotating spinning head 52. The motor driven head 52 comprises a faceplate 53 on which are mounted three freely rotatable rollers 54 equi-spaced about the axis of the plate 53 which is bolted to a back plate 55 fixedly mounted to a motor driven mainshaft 56. The axis of the faceplate 53 is coincident with the axis of the tube. On completion of the tube closing operation the stroke is reversed, the vices 26 opened, the stop 57 returned to its starting position and the motorised roller 26 operated in reverse to pass the finished tube to a buffer adjacent to an off loading rack 13 of a construction similar to that of the rack 12. Finally the tube is pushed by air cylinders on to the downwardly inclined rack 13.
