Abstract: 621,437. Making dynamo-electric rotors. SCOPHONY, Ltd., and CLARKE, H. F. Feb. 25, 1947, No. 5486. [Class 83 (ii)] A method of making a squirrel-cage rotor comprises assembling the laminations 1 and bars 3, staggering the assembly and then simultaneously applying axial pressure to all the bars by means of a circular knife edge which bifurcates the ends and clinches the prongs so formed. Preferably, the pressure is applied by two circular knife edges 4 of such diameter that each will bifurcate and clinch all the ends of the bars at one end of the assembly, as shown at 5. The bars are then preferably soldered to the end plates 2. If, however, end plates are not employed, an electrical connection between the bars can be obtained by dipping the ends of the rotor in liquid solder.

Abstract: 731,069. Tyre removers. BUCKLE, H. May 11, 1953 [March 5, 1952], No. 5754/52. Class 144 (1). In a tyre remover comprising a plurality of tyre-engaging pushers 29 the pushers 29 cooperate with associated rim-gripping members 42 which, after operation of the pushers 29 to force the tyre wall away from the rim, are operable to withdraw the wheel from the tyre. As shown, the tyre-carrying wheel is supported on the base 52 of a mobile frame 39 on which is mounted a spider 30 for movement towards the tyre by hydraulic rams 36, 37. Each pusher 29 is inwardly curved to provide a toe 35 and is pivoted to a carriage 31 having adjustable rack and tooth engagement with an arm of the spider 30. The rim-gripping members 42, one for each pusher 29, are pivoted at one end to the displacement head 44 of a ram 46 centrally supported on the spider 30. In operation rams 36 and 37 are operated by pressure fluid, supplied by a pump 40, to lower the spider 30 whereby the pushers 29 force the tyre away from the wheel rim flange 49. Continued movement of the spider 30 causes the pushers 29 to pivot inwardly so that their toe portions 35 move under the rim flange 49 thereby moving the associated gripping members 42 into rimgripping position. The ram 46 is then operated to withdraw the wheel from the tyre. With the pressure in the rams 36, 37 and 46 released the pushers 29 and members 42 are pivoted to clear the wheel and the spider 30 raised by a hand winch 50.

Title: Improvements in electric signalling systems comprising concentric cables
IPC: H04B3/34
Filed: 1938-02-25
Abstract: 499,077. Preventing inductive disturbance. SIEMENS & HALSKE AKT.- GES. Feb. 25, 1938, Nos. 6071 and 6072. Convention dates, March 1, 1937 and Jan. 27, 1938. [Class 40 (iv)] Coaxial cables transmitting in the same direction are arranged in pairs, and the direction of the signal currents is reversed in one member of each pair at the middle of a section. Mutual interference in one half-section is thus neutralized in the other. The reversal may be effected at or between repeater points. In the latter case, the reversal points may be bridged by chokes or resistances 25, 26 to provide a direct current path between the conductors transmitting in the same direction. In a system involving the transmission of highfrequencies carrying television and lower frequencies such as multiplex carrier telephony, the high-frequency repeaters, which appear at more frequent intervals than those for the lower frequencies, have byepaths for these frequencies and the reversal in direction of the lower frequency currents in successive half-sections may be effected in the byepaths. Cross-talk at the high-frequencies is ignored. U.S.A. Specification 1,950,127 is referred to.
