Patent GB-750575-A (GB)
Title: An improved mechanical torque amplifier
IPC: G05G19/00
Filed: 1954-07-07
Abstract: 750,575. Escapement mechanism.. LANDIS & GYR AKT.-GES. July 7, 1954 [July 15, 1953], No. 19938/54. Class 80(4) An escapement mechanism providing a follow-up control with torque amplification from a control shaft 6 to a driven shaft 10 comprises a gear wheel 21 meshing with gears 7 and 22 on the control and driven shafts 6, 10 respectively and carried in a frame 18, 19 secured to a spindle 17. The spindle 17 also carries a pallet 23 which co-operates with a spring-arm 25 secured to a shaft 9 of a continuously driving motor which is geared to the driven shaft 10 through gears 8, 11. On rotation of the control shaft 6 in the direction of the arrow the gear 21 rolls on the driven gear 22 and rocks the frame 18, 19 downwards about the axis of spindle 17. This movement releases the arm 25 from the pallet 23 and the driving power of shaft 9 is transmitted through gears 8, 11 to driven shaft 10. This results in a restoring movement of the frame 18, 19 and gear 21 upwards to move the pallet 23 back into a position to reengage arm 25 after it has made one revolution. The ratios of the gears are chosen so that four releases of the pallet 23 take place during each revolution of control shaft 6 and the driven shaft 6 completes a revolution in four corresponding steps. The spindle 17 is gapped to allow passage of the arm 25 on release by the pallet and the rocking movement of frame 18, 19 is limited by a forked end 26 thereof cooperating with an abutment 5. In a modified arrangement the pallet cooperates with four arms on the driven shaft itself the operation being otherwise similar. In another modification the control and driven gears are co-axially arranged and the intermediate gear 21 is formed as a planetary gear engaging both of the control and driven gears and supported in a carrier rockable about the axis thereof. A pallet on this carrier co-operates with an arm on a driving shaft geared to the driven shaft.

Abstract: 1374247 Photo-flash control circuit PONDER & BEST Inc 24 Aug 1971 [11 June 1971] 20163/74 Divided out of 1374245 Heading G2A A flash tube 594 is energized by pulses from a generator 593, a photo-detector circuit 596 being connected to the generator to terminate pulse generation on receipt of a predetermined quantity of light. As shown, a pulse from a trigger circuit 595 triggers tube 594 and via capacitor 59304 and capacitor 59307 switches on transistor 59306 to turn on a thyristor 59301. This causes a supply capacitor 592 to discharge through a capacitor 59304 and tube 594 until capacitor 59304 is charged. This turns off thyristor 59301, and turns on thyristor 59302 whereby capacitor 59304 discharges through the tube. When capacitor 59304 is discharged thyristor 59302 turns off, thyristor 59301 turns on and capacitor 592 again discharges. This process is repeated to energize tube 594 by means of pulses until a photo-detecting integrating circuit blocks thyristor 59302 to prevent further generation. The charge remaining on supply capacitor 591 is thus conserved.
