Abstract: 973,433. Carrying conductors through partitions; mounting terminals. ALLMANNA SVENSKA ELEKTRISKA A.B. Feb. 10, 1961 [Feb. 13, 1960], No. 4988/61. Heading H2E. A gas-cooled electrical machine or apparatus is provided with a metallic connection throughbolt and electrically insulating material surrounding the bolt, the insulating material comprising a solid resin derived from a completely polymerizable resin, applied around the bolt, and reinforced with synthetic organic fibres applied around the bolt in extended state obtained during manufacture and which shrink when subjected to heat during curing of the resin. If cold-setting resins are used the heat evolved by the setting reaction is sufficient to shrink the fibres. A completely polymerizable resin is a completely reactive polymerizable composition such as a solventless resin or a resin containing a solvent which is completely reactive with the resin. As shown, part of the casing 4 of a hydrogen-cooled electrical machine is provided with a metallic through bolt 1 surrounded by insulating material 2 making a gas-tight seal with the bolt. Rubber sealing rings 5 from a gas-tight seal between the insulated bolt and the internal wall of the bore 3 in the casing, the rings being pressed between a washer 6 and a spacing ring 8 by a collar 7 screwed into the bore. The spacing ring is prevented from rotating by a projecting screw 9 which engages an axial groove 10 in the bore. In the many examples unsaturated polyester resins and epoxy resins are included as suitable completely polymerizable resins, while suitable fibres are of polyethylene glycol terephthalate, polyvinylidene chloride, polyacrylonitrile, polyamides, and cellulose-based materials, the molecules in these fibres being formed in an extended state during the normal process of manufacture. The fibrous material may be applied as tape or yarn, and the resin may be impregnated into this material before its application to the bolt, applied between layers of fibre as it is applied to the bolt, or impregnated with or without vacuum into a completed winding. The bolt may be given a thin coating of silicone rubber or other elastic material before the application of the reinforced resin, and to a limited extent the resins used may be mixed with powders or grain-shaped fillers such as quartz powder or mica powder.

Filed: 1928-02-21
Abstract: 285,835. Lorenz Akt.-Ges., C., (Assignees of Ristow, A.). Feb. 22, 1927, [Convention date]. Receiving systems and apparatus; tuning apparatus, control of.-A distant wireless receiver is energized, connected to the aerial, and tuned to a desired wave length from a .distance, the necessary control currents being conveyed by the low-frequency transmission line. A second receiving set is provided as a standby, and is brought under control by means of a second switch which reverses the direction of the line currents. The second receiver can only be operated when the first is switched off. Provision is made for preventing the tuning point being lost by the over-running of the driving motor. The closing of the switch ST<2> at the listening point closes a circuit through the transmission lines L'', L<2> to earth (a) through a relay MR which drives the motor HM in one direction, and (b) through a relay Rt. The motor HM drives a chain of gearing comprising a switch-operating wheel Sch and a magnetic clutch TM<2> which serves to rotate the control knob K of the wireless receiver E<2> until the desired signals are heard in the telephones T over the lines L', L<2>. The switch ST<2> is then raised and the relay MR is broken. Simultaneously the relay Rt feeding the magnet clutch TM<2> is opened, to prevent the tuning-control knob K from being shifted as the motor HM runs down. A three-pole switch arm DR, operated by stops on the wheel Sch, ensures a holding contact at the upper magnetized relay M so long as the wheel rotates in one direction, and a similar holding contact at the lower relay M if the direction of rotation is reversed in order to bring in the standby receiver E\ but only after a point has been passed where the valves of the first receiver are switched off. The tuning adjustment of the distant receiver can be checked locally by the current passing through the milliammeter MA.
