Abstract: 1,189,948. Automatic circuit breaker. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY I PROEKTNOKONSTRUKTORSKY INSTITUT ELEKTROAPPARATOV. 3 April, 1968, No. 15970/68. Heading H1N. In an automatic circuit breaker the fixed contact is supported on a coil structure arranged to generate electrodynamic forces. The coil is formed by two rigid elements 15, 16 pivoted and connected together at 27. The element 16 is screwed to the moulded casing 1 of the breaker in either of two positions shown respectively in Figs. 2 and 3. The other element 15, which is relatively movable against the action of springs, carries the fixed contact 20 and an arcing horn 23. In Fig. 2, the forces generated by the current flow in the parallel parts of elements 15, 16 are such as to tend to move element 15 clockwise about pivot 27 and thus to open the contacts under short-circuit conditions to provide current limiting. In Fig. 3 the forces tend to increase contact pressure under heavy currents. The movable element 15 is slit longitudinally the two parts being coupled by a roller 25 sufficiently loosely to allow self-alignment of the contacts. The contacts separate in an arc-chute (7) provided with a flame grid (9) and the circuit breaker (Fig. 1, not shown) is provided with conventional tripping devices (4) and quick-acting manual operating mechanism (2).

Abstract: 355,711. Reinforced building slabs. FOURCADE, C. A. HOUQUES-, 56, Rue du Saujon, Bordeaux, France. May 26, 1930, No. 16140. Convention date, July 10, 1929. [Class 87 (i).] A wire-netting reinforcement is formed of parallel wires connected hy separate fasteners curled round the wires and fastened thereto by hammering. The Specification as open to inspection under Sect. 91 (3) (a) describes a machine in which the wire-netting is manufactured and immediately incorporated in fibro-cement to form reinforced slabs particularly suitable for roofing. The cement material is mixed in a hopper 28, Fig. 5 (Cancelled), and discharged down a shoot 29 on to the netting 32 which has been manufactured in the part of the machine shown on the left. A cross-bar 35 reciprocated up and down by rods 37, lever 39, and cam 41 carries rows of plungers 33 acting to pack the cement into the wire meshes. The wire cement sheet then passes between the conveyer belts 44, 45 and between rollers 46, 46a driven by gearing from the shaft 42, over a belt conveyer 52 passing around drums 50, 51 and between a table 56 and platen 57 on a carriage 55 mounted on rollers 54 and reciprocated along the frame 53 by a cam on shaft 42 engaging a roller on an arm 76 on a shaft carrying a lever 77 connected by a link 78 pivoted at 79 to the carriage. The platen 57 is suspended from a cross-bar 59 and is pressed down by spring washers 61 ; the cross-bar 59 is connected to lift rods 60, 60a engaging tracks 84 on pivoted levers 82, 82a operated by link 81 ani arm 80 actuated by another cam on the shaft 42 so that the platen 57 is depressed only when the carriage 55 is moving to the right. The cement sheet is cut into slabs by a shear blade 62 carried by a cross-bar 63 on the reciprocating carriage 55; vertical movement of the shear blade is effected by links 65, lever 88, link 87 and arm 86 actuated by another cam on the shaft 42. The slabs are discharged from the machine by a belt conveyer 90 passing over a drying plate 91. In a modification, Fig. 11 (Cancelled), the wire cement sheet is pressed by rollers 91, 92 actuated by gearing from the shaft 42; the shear blade is mounted on an independent carriage 96 reciprocated horizontally by the linkage 97 .. 100 actuated by a cam on shaft 42, and the shear blade is reciprocated vertically by linkage 101, 102, 103. This subject-matter does not appear in the Specification as accepted.

Patent GB-893429-A (GB)
Title: Dispersion polymerisation
Inventor: OSMOND DESMOND WILFRID JOHN
IPC: C08F279/02
Filed: 1957-05-27
Abstract: As coating compositions there are used dispersions of polymers in organic liquids, in which the polymers are insoluble, which have been produced by polymerizing at least one acrylic or vinyl benzene monomer in the presence of a catalyst and a colloid which yields a gel or thick liquid when dispersed or dissolved in the organic liquid in a proportion of less than 10% by weight.  Such compositions may be pigmented and plasticised in the usual ways. In an Example (5) glass and previously primed steel panels are sprayed with a composition obtained by polymerizing method methacrylate in a mixture of mineral spirits and iso-octane containing polyisobutylene as a colloid and adding dioctyl phthalate and titanium dioxide to the thus produced dispersion, and stored.ALSO:Stable dispersions of polymers in organic liquids in which the polymers are insoluble are produced by polymerizing at least one acrylic or vinyl benzene monomer dissolved in the organic liquid in the presence of a catalyst and a lyophilic colloid which yields a gel or thick liquid when dispersed or dissolved in the organic liquid in a proportion of less than 10% by weight. Monomers specified are acrylic and methacrylic acids, amides, nitriles and esters, e.g. methyl methacrylate, 2-ethoxyethyl methacrylate and ethyl acrylate, and styrene, divinyl benzene and alkyl derivatives thereof, e.g. vinyl toluene.  The choice of the organic liquid depends upon the polarity of the monomer to be polymerized, for example methyl methacrylate is polymerized in a non-polar liquid, such as a paraffin hydrocarbon, whilst styrene or vinyl toluene is polymerized in a polar liquid, such as ethyl alcohol or methyl alcohol.  The choice of colloid depends upon the polarity of the organic liquid, colloids such as natural rubber, polybutadiene and polyisobutylene being used with non-polar solvents, and colloids such as polyvinyl alcohol and polymethacrylic acid being used with polar solvents.  Catalysts specified are benzoyl peroxide, tertiary butyl hydroperoxide and azodiisobutyronitrile.  A surface active agent may be present in the polymerization medium, e.g. non-ionic agents, sulphonated oils, sodium soap and soaps of polyvalent metals. The dispersions may be used in coating applications, for which purpose they may be used in conjunction with plasticizers, e.g. dioctyl phthalate, and pigments, e.g. titanium dioxide.  The Provisional Specification describes also the application of the above process to other monomers, e.g. vinyl acetate, vinyl chloride, allyl acetate, diallyl adipate, diethyl maleate, maleic anhydride, dimethyl itaconate and dimethyl acetylene dicarboxylic acid ester.  In an Example (1) a process is described in which vinyl acetate is polymerized in iso-octane containing crepe rubber.
