Abstract: 452,888. Distant - control systems. SARBEY, M. D., 265, Parkside Drive, Bay Village, Ohio, U.S.A. July 6, 1935, No. 19384. [Class 40 (i)] [See also Groups XXXIX and XL] In a system for selectively controlling a plurality of devices, the control is effected by impulses of different strengths applied over the line wire or radio link and acting at the receiver upon a plurality of differently-biassed valves. The system may be employed for operating a type-printing telegraph or setting up a telephone connection. As shown a plurality of differently biassed valves T<1> .. T<5> are provided at the receiver and are adapted to control relays M1 ... M5. Each relay is provided with two sets of contacts, one set for effecting the desired control and the other set, which upon operation of the relay opens prior to the closure of the first set, being connected in series with similar contacts of the other relays so as to render those relays inoperative. The transmitting station is provided with a plurality of keys K1 ... K5 adapted to apply different potentials to the line wire. The valves may be connected to the line wire at remotely spaced points. In a modified system each valve controls a pair of relays one of which is quick acting and the other delayed in its action. The signals incoming to the receiver may be amplified if desired. In a further modification, pairs of valves are provided at stations distributed along a line wire, the valves at each station being differently biassed and the bias of the second valve at one station being the same as that of the first valve at the next station. Upon application of a controlling voltage to the line wire both valves at stations of lower bias become operative, the second valve at each unwanted station rendering the output of the first valve inoperative, whilst at the wanted station the first valve only is operated to effect the desired selection. The different controlling voltages may, if desired, be derived from a photo-electric cell.

Filed: 1959-06-08
Abstract: 873,121. Protective cut-out arrangements; control of motors. WESTINGHOUSE ELECTRIC CORPORATION. June 8, 1959 [June 17, 1958], No. 19503/59. Classes 38 (3) and 38 (5). A protective system for an apparatus, such as a dynamo-electric machine, comprises a temperature-sensitive resistance element 24 embedded in a current-carrying winding 30 of the apparatus and connected in series with an A.C. supply 48, the operating coil 46 of a D.C. relay 45, and a rectifier 49. The element 24 has a positive temperature coefficient and under normal conditions the relay coil 46 is sufficiently energized to maintain closed its contacts 44 in the circuit of a contactor operating coil 36. In the event of overheating, the resistance of the element 24 increases suddenly causing the relay to open the contactor operating circuit. Should the system fail due to a short-circuit between leads 52, 53, the high impedance of the relay to alternating current results in the opening of the contacts 44 and the opening of the contactor. Specification 865,649 is referred to.

Abstract: 1473561 Rotary positive-displacement fluidmachines W H BIBBENS 3 May 1974 [3 May 1973] 19547/74 Heading F1F In a Wankel-type I.C. engine each apex seal blade 124 of the rotor has on its leading side adjacent each end thereof a cam surface 178 on which a projection 195 formed on an arm 196 of an associated coupling seal 122 bears when, owing to friction between a portion 158 of the outer end surface of the coupling seal and the adjacent housing end-plate, the coupling seal pivots about its axis in a direction 52a. The seal blade also has at each end a cam surface 174 engaging with a cam surface 148 on a "retaining member" 120 fixed in the rotor. The pressure of the projections 195 on the surfaces 178 not only urges the seal blade radially outwards to hold it against the inner peripheral wall of the housing but also presses the coupling seals against the housing end-plates and moreover, centres the seal blade relative to the rotor end-surfaces. The seal blade is also urged towards the said wall by a spring 126. Springs 128 bias the coupling seals towards the housing endplates. The retaining member may be dispensed with, a groove for the seal blade and recesses for the coupling seals then being formed directly in the body of the rotor. The seal blade may have pressure-equalizing passages therein, Fig. 14A (not shown). The coupling seals may be modified so as to have projections formed on the leading walls of the seal-blade grooves therein and engaging with respective cam surfaces on the seal blades, the arms 196 being dispensed with, Figs. 23-26 (not shown). To obviate damage due to pressure pulses in the combustion region striking the seal blades the grooves for the latter may be inter-connected by passages in the rotor, Figs. 27-42 (not shown), the excess pressure being relieved through gaps between the seal blades and the groove walls, and the corresponding said passages, to a region at a lower pressure.
