Title: Device for Generating an Electric Spark by Striking a Piezo-Electric Element.
IPC: F23Q3/00
Filed: 1967-10-24
Abstract: 1,171,808. Piezo-electric generators. KYOKUTO ELECTRIC CO. Ltd. 24 Oct., 1967 [25 Oct., 1966; 10 Nov., 1966; 31 May, 1967 (2)], No. 48386/67. Heading H2A. In a piezo-electric spark generator, e.g. for gas ignition, the element 13 and spring-loaded striker 2 are enclosed in a box 1 which is surmounted by an actuating bar 18 sliding in guides 9, 16 projecting from the box and its lid 11 respectively. The element is retained in a tapered clamp 27 by axial pressure at its other end by a metal diaphragm spring 32 resting against a shoulder on the element. The output of the element passes to lead 25. When the actuating bar is moved to the left against spring 20, a detent spring 24 engages a projection 6 standing up through slot 12 to force the striker 2 in a leftward direction. The detent spring is eventually raised by engaging ramps 15, to release the projection 6 and so allow the striker to move to the right and strike the element.

Abstract: 1363117 Automatic speed control SOC D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE 29 Oct 1971 [5 Nov 1970] 50514/71 Heading G3R [Also in Division H2] The driving winding 7 of a brushless D. C. motor is energized when the output signal of a circuit 11 which phase shifts the output of a detector winding 8 by 90 degrees irrespective of the frequency of the detector winding output signal exceeds a threshold level set by a voltage generator 12. The speed of the motor is determined by the width of the current pulses fed to winding 7 from amplifier 9 which in turn is determined by the threshold voltage. Voltage generator 12 may be controlled manually, or, Fig. 3 (not shown) by a circuit (14) which causes the threshold level to be increased as the difference in amplitude of the outputs of circuit 11 and detector winding 8 decreases, circuit 11 being in this case an RC integrating circuit. Alternatively, Fig. 4 (not shown), the motor is synchronized with a frequency generator (15) which, together with the detector winding 8, is connected to a phase comparator (16) which causes the threshold voltage to be zero as long as the detector output frequency is less than the reference frequency and thereafter causes the threshold voltage to increase until the output of the detector winding is in phase with the output of the frequency generator (15). All embodiments include a current limiter 17 and a starting circuit 18 which feeds to the detector winding 8 a current pulse causing the rotor to move to a position where its poles are displaced by 90 degrees from the driving winding 7, then feeds a pulse to the driving winding and is thereafter disconnected. The motor may include a permanent magnet rotor 3, Fig. 7 (not shown) surrounding a ferrite core stator carrying the driving and detector windings each of which may comprise several coils.
