Abstract: 1456855 Seaming non-metallic sheet material DUNLOP Ltd 1 March 1974 [9 March 1973] 11591/73 Heading B5K [Also in Division F2] A rubber-plastics composite, the rubbers and plastics being selected from a list given in claim 1, is made by causing relative frictional movement between a thermoplastic plastics component and a vulcanized rubber component, the components being fusion-bondable, until the plastics surface in contact with the rubber melts, and allowing the plastics to solidify. The relative movement may be rotary, angular or linear and may be continuous or oscillatory. One or both components may be moved. Specified techniques are the use of a lathe to rotate one component and ultrasonic welding. The components may be relatively moved for 1-10 sees. under 100- 500 kN/m<SP>2</SP> pressure. The application of pressure during solidification and of external heating during melting are optional. The surfaces may be pretreated with acidified sodium hypochlorite, concentrated nitric acid, aqueous trichloroisocyanuric acid, sodium dichloroisocyanurate or 4(p-carboxyphenyl)-1, 3, 5-triazoline-2, 4-dione, or by UV-irradiation, glow discharge or flame. A lubricant may be applied between the surfaces. Delicate components may be hardened by freezing in liquid nitrogen or dry ice-acetone. Additional rubber, plastics or metal components may be included. One of the components may be an intermediary for bonding two incompatible materials. In examples, flat-ended rods or cylinders are bonded to each other, to sheet materials and to plastics-coated metal buttons via the flat face, and two flanged open boxes are bonded together to form a hollow composite.

Title: Improvements in and relating to protective devices for electric circuits
IPC: H02H3/30
Filed: 1921-04-22
Abstract: 188,001. British Thomson - Houston Co., Ltd., and Fitzgerald, A. S. April 22,1921. Protective arrangements of the Merz-Price type three-phase systems providing separate protection against faults between phases and against faults between any phase and earth as in Specifications 141,121 and 174,769 comprise current transformers in each phase the transformer in the middle phase consisting of two separate, parts the secondaries of which have half the output of those in the other two phases. Each one of the secondaries in the middle phase is connected across one of the secondaries in the outer phases, respectively. The secondaries are connected from end to end by pilot wires so that faults between two phases will cause currents to flow in two of the pilot wires, whereas faults between a phase and earth will cause current to flow in the other pilot wire. As shown in Fig. 2 applied to a three-phase distribution system similar current transformers 4, 6 are connected in two of the phases at each end and two transformers 5 are connected in the other phase at each end and have double the number of secondary turns and cores of half the cross-section of those of the transformers 4, 6. Transformers 4, 5 and 5, 6 are interconnected in separate circuits with a common point O and pilot wires interconnect equipotential points between ends. Faults between phases operate the relays 7 and faults to earth operate the relays 6. The adaptation to a circulating current system is shown in which a relay 8 between equipotential points of the pilot wires takes care of faults between phases and a relay 9 between the mid-point of the relay 8 and the middle pilot wire takes care of faults to earth.

Title: Improved Means for the Desired Distribution of Load and Current or Direct-current Units connected in Parallel.
IPC: H02J1/10
Filed: 1917-08-21
Abstract: 109,799. Akt-Ges. Brown, Boveri, et Cie. Aug. 21, 1916, [Convention date]. Systems for continuous-current motors only.-The load on two or more parallel connected direct-current units is distributed uniformly by means of separate regulators which are controlled by currents pro. duced by the differential units. Three direct-current generators g<1>, g<2>, g<3> are shown in Fig. 1 connected to bus bars through resistances n<1>, n<2>, n<3> and their field circuits include resistances r<1>, r<2>, r<3>, controlled by quick action regulators with rolling contacts. The torque produced by the regulator windings is balanced by a weight p. Additional windings st<1>, st<2>, st<3>, are connected between the inner terminals of the resistances n<1>, n<2>, n<3>, respectively and a common point. If the distribution of the load is altered by the variation of the current in one generator, the current flows through the additional winding of its regulator in one direction and through the other additional windings in the other direction. The three regulators thus act to restore the load balance. In a modification, only one regulator is responsive to the voltage and the others have permanent magnets. The load taken by a number of motors may be distributed between them by regulators acting in the same way. Specifications 15035/06 and 27069/12 are referred to.

April 23, 1934, No. 12163. [Class 83 (i)] [See also Group II] A composite strip is made by applying a layer of tin, solder, or the like to the surface of a strip of hard metal of high melting point, and passing the strip through a pouring gate into which molten bearing metal is poured, the strip passing out through a sizing opening bounded by a movable wall of the gate. A steel strip 1 passes over a roller 12 and into a bath of molten tin 11, excess tin being removed by wipers 6. After passing over a roller 13 the strip enters a heated, enclosed chamber 14 and passes beneath a reservoir 63 of babbitt metal periodically charged from a ladle 17. The strip receives a coating 21, the thickness of which is determined by a die aperture formed between an adjustable member 35 and a lower member 15. The surface of the strip may be roughened before tinning. In a modification, the tinning bath 10 is replaced by a reservoir similar to that for the bearing metal 63. In a further modification, a strip of tin or solder is placed on the steel strip 1 and the two strips pass through a heating chamber to render the tin or solder plastic, and then pass beneath the reservoir of bearing metal.
