Title: Improvements in or relating to bistable electrical storage circuits
IPC: G11C11/411
Filed: 1965-03-12
Abstract: 1,094,602. Bi-stable circuits. RADIO CORPORATION OF AMERICA. March 12. 1965 [March 20, 1964], No. 10553/65. Heading H3T. A cross-coupled bi-stable circuit with transistors 10a and 10b has one feedback path through an AND gate 40c to the other input 62 of which reset pulses are applied; one or more further AND gates 40a, 40b have information inputs 50, 58 and a common strobe input 52, the strobe and reset pulses being of opposite polarity, coincident or slightly overlapping in time and of amplitude equal to the output of the bi-stable circuit; the outputs of the AND gates are combined to produce an OR function, e.g. by passing them through an OR gate 70 to the base of transistor 10a. In the " set " state the output at (0) is zero and at (1) is V so that the AND gate 40c and OR gate both give outputs of - V to hold transistor 10a conducting. On arrival of the positive reset and negative strobe pulses the AND gate 40c gives zero output, and in the absence of incoming information the other AND gates will also give zero so that the potential at 74 rises to zero and the bi-stable circuit changes over. The AND gate 40c is now held to zero by the voltage from (1) and termination of the reset and strobe pulses has no effect. If one information input falls to - V, no result occurs until the next strobe pulse which operates the appropriate AND gate and the OR gate and changes the bi-stable circuit back to the set condition. Termination of the reset and strobe pulses has no effect as before. When the information signal ceases or another information input occurs nothing will happen until the reset and strobe pulses reset the bi-stable circuit. The end of the strobe pulse should preferably be a little later than the end of the reset pulse to make sure that the AND gate 40c falls to - V before the other AND gates rise to zero, to prevent false resetting of the bi-stable circuit. If transistors are used instead of diodes in the AND gates, the OR gate may be replaced by a direct connection. In a modification (Fig. 7, not shown) AND and OR gates are included in both of the feedback paths of the bi-stable circuit.

Title: Wind motors
Inventor: CHILMAN JOHN ALFRED
IPC: F03D7/02
Filed: 1963-03-18
Abstract: 987,032. Wind motors. DOWTY ROTOL Ltd. Feb. 25, 1964 [March 18, 1963], No. 10606/63. Heading F1T. A wind motor mounted on a retractable support on a vehicle includes means to retard the rotor prior to retraction operable in conjunction with positioning means to stop the rotor in a predetermined position so that the wind motor presents its overall smallest crosssectional area to an opening in the wall of the vehicle for retraction of the wind motor through the opening. A wind motor 11 mounted on an aircraft to drive an emergency hydraulic pump 28 comprises a two-bladed rotor 12 mounted on a retractable leg 15 controlled by a jack 19. When the aircraft main hydraulic pumps 33 are operating normally leg 15 is held in a retracted position within the aircraft by a locking peg 63 engaging recess 16a in the leg pivot 16 under the action of hydraulic pressure fed to the right-hand side 54 of a servo-piston 57. The same pressure fed to the right-hand side 52 of servo-piston 50 holds the end portion 77 of a locking rod 41 in engagement with recess 78 in plate 76 attached to the rotor 11 so as to lock the blades 13 in a position parallel with leg 15. Hydraulic pressure on the right-hand side 70 of jack piston 66 holds the operating rod 21 in the retracted position against the action of spring 19a. Upon failure of main pumps 33 pressure in lines 38, 53, 64 falls and locking peg 63 is released by spring 58 acting on servo-piston 57. Simultaneously leg 15 is lowered under the action of spring 19a in jack 19. When the fully lowered position is reached peg 49, under the action of spring 51, engages recess 16b to lock the leg and simultaneously locking rod 41 is released from recess 78 to allow the rotor 11 to rotate and drive emergency pump 28 through gearbox 27. A governor 29 controls the pitch of the rotor blades 13 to maintain the rotor speed constant. When hydraulic pressure from the main pump is restored in lines 38, 53 servo-piston 57 moves to the left and overrides governor 29 in such a manner that the blades 13 are moved beyond their feathered position into the reverse pitch range. The rotor 11 therefore slows down and then reverses, at which point locking rod 41 re-engages in recess 78 to lock the rotor with the blades 13 parallel to leg 15. An hydraulic accumulator 30 ensures that pitch reversal occurs. Leg 15 then retracts into the aircraft under the action of main pump hydraulic pressure.

Abstract: 1500370 Protecting generators KRAFTWERK UNION AG 14 March 1975 [29 March 1974] 10865/75 Heading H2K A generator is automatically disconnected (12) from a distribution system if, on occurrence of a fault anywhere in the system, it drifts out of synchronism. This prevents damage to the generator when the protective system dealing with the fault subsequently recloses. A detector 11 monitors the amplitude of the positive phase sequence voltage of the system at the location of the generator. If there is a large drop in this voltage, signifying a fault close to the generator, a threshold detector 21 trips the circuit breaker 12. If, however, there is a smaller voltage drop, signifying a more remote fault, a threshold detector 20 puts into action a phase monitoring circuit. The system frequency immediately prior to the occurrence of the voltage drop is stored (23) and subsequently continuously compared (27) with the instantaneous generator frequency. Any discrepancy is integrated (26) to give a measure of the total drift in phase of the generator, and if this drift becomes too great a threshold detector 31 trips the breaker 12.
