IPC: H02P1/04
Filed: 1924-08-12
Abstract: 242,705. Cox, F. B. Aug. 12, 1924. Controllers, with combinations of resistances.- Variable resistances, particularly for use with motor starters, comprise the combination of a group of unequal resistances R<1> - - R<4> with another group of resistances R<6> - - R<9>. Switches S<1> - - S<5> adapted to bridge corresponding contacts 2, 3 are operated cyclically so that each resistance R' - - R<4> and each series combination thereof is introduced successively into the circuit, and similar switches S<6> - - S<10> bridging contacts 2<1>, 3<1> cyclically insert the resistances R<6> - - R<9> individually and in parallel combinations into the circuit. The switches can be operated in the desired sequence by cams on a commor. shaft, which can be operated by hand or by a sclenoid and retarded by a dash-pot or a second solenoid sensitive to the back E.M.F. of the motor. The two groups of switches may be replaced by a drum controller. The modes of operating the switches are similar to those disclosed in Specification 227,135, and include the use of electromagnetic switches, the coils of which are energized by contacts on a rotatable disc, and of pneumatic switches with electromagnet cally operated valves. The cam-shaft can also be operated by a float actuated by variation of level of a liquid.

Filed: 1920-07-09
Abstract: 147,855. Reichenheim, O. Sept. 10, 1915, [Convention date]. Wireless telegraphy.-Objectionable effects due to atmospherics and other disturbing causes are eliminated by the use of a " series " conductor including condensers and inductances arranged to offer low resistance to (1) currents of frequency lower than a predetermined value, (2) currents of frequency higher than a predetermined value, or (3) currents of frequencies lying between predetermined limits. At the same time high resistance is offered in each case to the remaining frequencies. Or the conductor may be arranged to offer high resistance to frequencies between predetermined limits. When arranged to allow the required frequencies to pass, the conductor leads to a receiving telephone, but when arranged to oppose passage of the required frequencies the conductor is in parallel with the telephone. Fig. 1<a> shows a " series " conductor arranged to allow passage of a selected frequency range, and comprising a portion I with condensers in series and inductances in parallel allowing passage of frequencies higher than the lower selected limit, and a portion II with inductances in series and condensers in parallel, opposing passage of frequencies above the higher selected limit. Alternative arrangements are shown, and Specification 142,115 is referred to.

Title: A Synchronous Generator Rotor having a Direct Liquid-Cooled Winding
IPC: H02K3/22
Filed: 1967-05-01
Abstract: 1,191,123. Cooling dynamo-electric machines. BROWN, BOVERI & CO. Ltd. 1 May, 1967 [3 May, 1966], No. 19964/67. Heading H2A. The direct-cooled field winding on the rotor of a turbo-generator is connected, at least one end, as a two-layer lap or wave winding so that numerous liquid connections can be made at the winding heads and thus clear of the turns. By this means the conductors or turns of the winding may be cooled in parallel while being electrically in series. The slot-conductors are connected electrically and hydraulically in vertical pairs. In the form shown in Fig. 1, both winding ends 2, 2<1> are in waveform and the conductors 3 run circumferentially across the polar region. By this arrangement cooling liquid may be supplied or withdrawn at each end so that each conductor may be fed separately. As shown in Fig. 2, the conductor pairs 5, 6 are connected in parallel hydraulically and electrically by a connection-piece 8, also connected to feed pipes 7 which are connected, in turn, to headers (15, Fig. 8, not shown). The winding may be wave at one end and concentric at the other (Fig. 6, not shown). With this arrangement the cooling liquid inlet and outlet are in groups at the same end of the machine, each coolant circuit being a complete turn. Two similar windings may be placed, one above the other (Fig. 8, not shown). These windings may be connected in series by external connectors at the winding-heads which may lie between the winding-heads (Fig. 10, not shown). The windings may be energized in opposition for testing. Coolant is fed into and withdrawn from zones of the winding by connection to diametrically opposite header chambets (21), Fig. 9, sub-divided from a single annular chamber at the end of the rotor by separating walls (20) in the polar and neutral zones. The header chambers are connected to concentric supply and discharge channels (24, 25) by radial pipes (22). In each slot the conductors are at similar temperatures, thus avoiding thermal stresses. Reference has been directed by the Comptroller to Specification 1,107,134.
