Title: Improvements in and relating to magnetic devices
IPC: H02K55/00
Filed: 1965-02-22
Abstract: 1,097,202. Superconductor devices. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Feb. 22, 1965 [Feb. 21, 1964], No. 7478/65. Heading H1K. [Also in Division H2] A magnetic flux path switching device comprises superconductor magnetic shield means disposed to enclose a space containing magnetic flux and to provide shield members of controllable superconductivity to switch the flux from one path to another. In Fig. 1, the magnetic flux between the poles of magnet 4, 4a can be switched so that it penetrates space A in either an upward or downward direction according to whether magnetic screen elements 7, 7a, 8, 8a are in the superconductive or normal state. A conductive fluid flows through duct 3 (space A) so that an alternating current output can be obtained from polepieces 2, 2a by switching the conductive state of the screen elements. Superconductor elements 5 and 6 confine the magnetic field. The switching of the elements may be effected by varying an associated magnetic field or the current through the element, or the temperature. Magnetic field variation may be effected by surrounding the element with a plurality of coils (Fig. 2, not shown) specially positioned and carrying currents staggered in time, so that the magnetic shutter effect of the element results in a sinusoidal instead of rectangular, waveform at output terminals 2, 2a. Reference is made to the possibility of achieving the desired effect by mechanical movement of the superconductor shutter elements. Alternative arrangements are described in which the switched magnetic field is applied to an air cored coil, or alternately to one or the other of two coils wound in mutual opposition. If the main magnets 4, 4a are provided by d.c. excitation, a d.c.-c.c. inverter may be provided.

Abstract: 1392021 Selective signalling SPERRY RAND CORP 20 Feb 1973 [1 March 1972] 8181/73 Heading G4H [Also in Division H2] An electrical power supply for a ship comprises operating and standby generators and is such that upon malfunctioning of the operating generator, an alarm is actuated and the standby generator is placed on-line. Each generator is monitored by threshold sensors 17-21, Fig. 1 (not shown) for oil pressure, liquid level, cooling water temperature, voltage and frequency. When a malfunction is detected, a signal is sent to an alarm circuit (Fig. 2, not shown) which actuates an audible alarm and causes a gate (55) to pass a pulse train (57) to a lighting circuit (59-69) so as to provide a flashing visual alarm. Operation of an "acknowledge" means by a crewmember switches a flip-flop (47) so as to silence the audible alarm and alter the lighting circuit so as to provide a continuous visual signal. The detectors also signal an automatic transfer logic circuit (Fig. 3, not shown) which places the faulty generator off-line, checks that the standby generator is not malfunctioning and places it on-line when its voltage and frequency have reached acceptable levels.

Title: Improvements in or relating to clutches for conveying rotary motion
IPC: F16D23/04
Filed: 1946-02-11
Abstract: 615,507. Clutches. BROCKHOUSE ENGINEERING (SOUTHPORT), Ltd., and GATISS, A. L. Feb. 11, 1946, No. 8195/48. Divided out of 614,928. [Class 80.(ii)] A friction clutch transmits torque up to a predetermined figure above which relative slip causes engagement of a positive clutch without further movement of the operating member, the one member of the positive dog clutch being moved axially by the operating member to contact the other dog clutch member, which is mounted for axial movement against yieldable means preventing such movement, so that on slip of the friction clutch the two dog members can engage. A clutch driving member 21 is splined to the driving shaft 20 and carries rotationally connected thereto a pressure plate 25, a driving plate 24 and a rigid abutment plate 23, the pressure plate being urged axially towards plate 23 by the springs 26. A V-groove 32 is formed between a face of the member 21 and an adjustable ball engaging ring 29 in which is located a series of balls 33, radial movement of which caused by a ramp 39 on a sleeve 36 produces disengagement of the friction clutch, the driven element of which is formed by driven plates 34 splined to the driving shaft 35. The operating sleeve 36 has a series of inwardly extending splines 40 whose ends 41, adjacent to the spring-loaded driven member' 46, are tapered in the direction of rotation, and are engageable on axial movement of the sleeve 36 with corresponding tapered splines 44. Movement of the sleeve 36 to the right first allows the balls to move radially outwards to engage the friction clutch, then the spline teeth 41, 44 engage after they have been substantially synchronized by the friction clutch, or if they are synchronized out of alignment, the member 46 moves against the springs 48 as the teeth meet in end-to-end engagement, full engagement occurring as soon as there is relative rotation due to torque above the predetermined maximum on the friction clutch. The invention is applicable to clutches used between a hydro-kinetic torque converter and a reverse or change-speed gear-box, where such a clutch is subject to a drag torque even when disengaged.

Title: Improvements relating to fuel control in gas-turbine engines
IPC: H02P23/16
Filed: 1962-03-02
Abstract: 940,611. Automatic control of gas turbines. DAIMLER-BENZ A. G. March 2, 1962 [March 2, 1961], No. 8251/62. Heading G3R. In a control system for a gas turbine having a compressor 11 and a turbine 14 fuel is delivered to a burner 38 from a tank 36 by a pump 35. The temperature of the combustion gases is sensed by parallel connected thermo-electric devices 18 connected in the input of an amplifier 22 in series with a potentiometer 21 supplied from a source 23. The voltage tapped from the potentiometer is determined by a surge-limiting arrangement 5 which comprises a barometric capsule 72 responsive to the compressor delivery pressure limiting the movement of a pinion 77,positioned by a pilot's lever 78 and connected to the potentiometer slider, through a spring 75 and rack 76 in opposition to a spring 81. The output of the amplifier is zero when the gas temperature is at the desired value and a relay 28 is unenergized and a resistor 40 is in series with the armature of a pump driving motor 31. For a positive output voltage from the amplifier, representative of the actual temperature being below the desired value, the relay 28 is energized and the resistor 40 short-circuited causing an increase in pump delivery. Feedback is applied to the amplifier 22 from the armature circuit of the motor 31 through a delay network 44. The speed of the turbine is limited by a relay 56 isolating the contacts of the relay 28 when a Zener diode 62 becomes conductive at a predetermined voltage from a tachogenerator 50, driven by the turbine 14, set by a potentiometer 59. In a modification, the relay 28 controls the excitation of a Ward Leonard generator supplying the fuel pump driving motor; the turbine has a separate power turbine which is connected to the speed-limiting arrangement. In another modification, the amplifier 22 and the speedlimiting arrangement energize servomotors which act in opposition through a worm-gearing to vary the delivery of a pump driven by the turbine driving the compressor. In further modifications, the relays are replaced by transistors and a free-wheeling clutch enables the tachogenerator to be driven by whichever turbine shaft has the highest speed.
