Abstract: 1380151 Protective arrangements STANTON MAGNETICS Inc 21 March 1972 [16 April 1971] 13256/72 Heading H2K [Also in Division H4] Overload protection for a sound reproducer 14 such as a dynamic or electrostatic loud-speaker or headphone, comprises a circuit-breaker 24, e.g. of electromagnetic type or consisting of a fuse, connected between one output terminal 16 of a driving device 12 and one input terminal 20 of the sound reproducer 14. In operation, the driving signal is sampled via two resistors 28 and 30 forming a voltage divider. The sampled signal is rectified by a diode 44 and stored in a capacitor 34. When the capacitor 34 is charged to a certain point by the sampled signal exceeding a threshold level for a sufficiently long time, or by a signal having a closely spaced series of instantaneous parts sufficient to maintain the charge on capacitor 34 at a required value for a - sufficiently long time, it gates a S.C.R. 36 which then becomes conductive and shorts out the sound reproducer 14. The current through circuit breaker 24 rises sharply and, if S.C.R. 36 remains fired for a sufficiently long time, circuit breaker 24 opens, thereby disconnecting the sound reproducer 14. Resistor 26 represents the resistance of circuit breaker 24.

Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1930-05-01
Abstract: 349,264. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Fuller, R. A. ; 5012, Florence Avenue, Philadelphia, U.S.A.) May 1, 1930, No. 13484. Convention date, May 1, 1929. [Class 38 (v).] An arrangement for reconnecting a supply system 1 to a load 2 which may or may not be fed from other sources, as in Specification 198,683, [Class 38 (v), Electric switches &c.], enables such reconstruction to be effected in conditions when the load is not otherwise fed and its resistance is high relative to that of a resister connected across the opened circuit-breaker. The overload coil 5, in responding, de-energizes the closing and holding coil 4 so that the breaker 3 is opened and connects at 21 the time-relay 17 across the supply 1. Also connected across the opened breaker 3 are a relay 8, which is arranged to close contacts 22 when the voltage across it is less than a given amount such as would obtain when the load 2 is energized from another source, and a relay 9 which closes contacts 23 when the voltage across it is above a given amount such as would obtain when no other source is feeding the load. In the latter case, the contacts 18, 23, 21 make a circuit for the winding 10 of a reclosing relay 7, the operating winding 11 of which is connected across the load 2 so as to be responsive to the voltage thereof, and a circuit for a relay 15 which shunts the resister 14 across the opened breaker. A dashpot 26 retards the opening of relay 9 which is insufficiently energized when the resister 14 is connected in circuit. When the load resistance is high enough, the winding 11 in cooperation with the winding 10 closes contacts 13 and connects the coil 4 in series with contacts 18, 23, so that the breaker 3 is closed. When the load is alternatively energized, however, the relay 9 is unable to respond, although 8 is sufficiently energized to open its contacts 22. When the voltage across the breaker falls sufficiently, however, the coil 4 is connected to the supply 1 over contacts 18, 22 and recloses the breaker.

Title: Gyro erection system
IPC: G01C19/48

Abstract: 678,242. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. May 31, 1950 [June 30, 1949], No. 13636/50. Class 97 (iii). [Also in Group XXXV] In a gyroscopic system the torque processing motors which, during normal operation of the system, maintain the spin axis in a predetermined direction are utilized to erect the spin axis from the position occupied thereby when the rotor is at rest and unenergized to substantially said predetermined direction before energizing the rotor and on energizing the rotor the connections to said motors are automatically switched over for normal erecting operation. As shown in a gyro-vertical in which the gyro rotor casing 10 is mounted in a gimbal 12, stator windings of a pitch pick-off 20 and the bank torque motor 22 are mounted on gimbal ring 12, the rotor elements being secured to the pitch axis trunnions 14. The rotor elements of bank pick-off 24 and pitch torque motor 26 are mounted on the bank axis trunnions 18 and the stator elements are mounted on the supporting member 16, on which are also mounted pick-offs 28, 30, the stators of which are fixed to the member 16 and the rotors of which are controlled by pendulous masses 32, 36 so as to maintain the rotors stationary with respect to the true vertical. The stator windings of the four pick-offs are energized from an A.C. source and the signals from the rotors of pick-offs 20 and 28 and similarly the signals from the rotors of pick-offs 24 and 30 are added algebraically and the resultant signals applied respectively to control the erecting motors 22 and 26 (see Group XXXV), so that these latter turn in such directions as to erect the spin axis. A time delay device is included so that after a period of switching on the power to the pickoffs a relay operates to change the connections of the torque motors 22, 26 so that motor 22 is controlled by signals from pick-off 24 and motor 26 is controlled by signals from pick-off 20 to maintain the spin axis vertical. During a co-ordinated turn of the craft, a control handle of an automatic pilot on operation disconnects the erection motor 22.
