Abstract: 1,225,288. Protective arrangements. GENERAL ELECTRIC CO. 18 June, 1968 [23 June, 1967], No. 28920/68. Heading H2K. An auto-reclosing ptotective arrangement comprises a high speed circuit-breaker 12 which is immediately tripped open when a signal is received from means 26... 32 responsive to a travelling wave on a protected circuit 10. A relay 46 determines whether the circuit-breaker should remain open or reclose and controls the operation of means 67 for energizing triggering means 66 to establish an arc to maintain the supply to the circuit 10 until the circuitbreaker contacts reclose. In the arrangement shown, a fault causing a travelling-wave on the circuit 10 results in an increase in voltage across a resistor 27 which is connected in series with a capacitor 26 between the circuit and earth. This increase in voltage causes a thyratron 30 to turn on so that a charged capacitor 32 can discharge through the trip coil 23 of the circuit-breaker. The relay 46 forms part of a protective system of the percentage differential type, the restraint coil not being shown. This relay remains unoperated when the fault is external to the protected section so that the closing of auxiliary contacts 70 of the circuitbreaker causes the energization of the oscillator 67 to energize the triggering means 66 of a vacuum gap device 60. The resulting arc in the device 60 maintains the supply to the circuit 10 until the circuit-breaker 12 is reclosed by a reclosing device 84 under the control of a relay 80 having its operating coil 81 in circuit with the contacts 70. If the fault is internal to the protected section, the relay 46 is energized and opens its contacts 47 to prevent or stop operation of the gap device 60 and to prevent automatic reclosure of the circuit-breaker, the relay being held open by a latch 90. In a modification, the circuit-breaker 12 is a vacuum switch provided with a trigger gap so that the switch contacts also function as the electrodes of a gap device, no separate device being provided, Fig. 3 (not shown).

Abstract: 729,070. Rotary motors. CLIFFORD AERO & AUTO, Ltd., and STRETTON, H. J. Feb. 5, 1954 [Nov. 17, 1952], No. 28931/52. Class 110 (2). A hydraulic, reversible, motor comprises a rotor c, provided with axially-sliding vanes h, the ends of which move through wave-like working chambers j inside fixed rings f. The supply of liquid is controlled automatically in response to variations of pressure of the liquid. As shown there are twelve working chambers g in each ring, and twenty-one vanes. For driving the rotor in one direction, motive liquid enters a port k leading to a chamber i and ports 7, 9 and is exhausted through ports 6, 8, chamber and a port m. A transverse bore n contains a freely slidable shuttle valve o for controlling a passage p through which liquid can pass (see line 22) and actuates a servomotor piston 18. Movement of the latter displaces a rod y to rotate, through rack and pinion mechanism s, w, curved members q, r. These contain ports 13 of different lengths, Fig. 1, so that, as the members q, r move onwards they successively cut off the supply of liquid to pairs of ports to put any desired number of working chambers out of actions. When the motor is at rest, the piston 18 is pressed to its left-band position by the spring 19. On starting the motor against a load, the pressure of the liquid supplied rises and acts through the passage p, line 22 and a succession of valves 24, 23, with springs 25 of different strengths, to supply the left-hand side of the piston 18 causing it to travel to the right (Fig. 1) and actuate the rack and pinion mechanism to open up successively the ports 12 leading to the working chambers of the motor. The liquid enters the piston 18 by way of an annulus 20 and holes 21. With diminution of the load, the right-hand valve will close and allow some of the liquid in the upper part of the cylinder 17 to escape through a port 27, in a valve 23 to an outlet. 28 leading back to the sump. The rings q, r may be adapted to control the opening and closing of the ports 12 in different ways. Other types of servo mechanism or manual actuation of the rings may be used. A restriction valve may be embodied to cause partial blockage of the liquid flow and thus act as a hydraulic brake. The motor may be reversible. The motor may be used for driving a wheel of a road vehicle, the pump being driven by the vehicle engine.
