Filed: 1973-12-19
Abstract: 1415559 Coin distribution device LANDIS & GYR GmbH 19 Dec 1973 [24 Sept 1973] 58816/73 Headings G4X and G4V A coin distribution device arranged on the outlet side of a coin checking means receives a coin 1 which is valid, through a tube 2, the coin then passes between driven rollers 3 and 4, which give the coin a velocity sufficient for it to pass through passage 5 and switching points 7. The coin is guided through a passage 11 and guide track 20 in the switch, into a discharge passage 27 which is preselected by a logic switching circuit in the coin checking means. From the discharge passage the coin falls to a coin storage compartment. If the coin is valid but deformed it will jam in the region of the guide track 20 by slightly pressing the flap member 21 away from abutment 19. When the logic switching circuit cuts the voltage to the solenoid 18, the coin switch rotates about axis 10 back into its starting position and before the actuating arm 15 comes into contact with abutment 13 the pin 25 lifts the flap 21 freeing the jammed coin which falls into a discharge passage 26 situated below it and is directed to a money box. In the starting position the switch actuating arm 15 is held against abutment 13 by the solenoid return spring and coins can pass through a passage 8 in the switch and may then pass through a guide passage 9 into the next switching point or may pass through the switching points if they are all in the starting position and into a money box. In a modification the switch and solenoid may be arranged so that the switch moves perpendicularly to the direction of movement of the coins.

Title: Drive circuit for inductive loads
IPC: F02P3/05
Filed: 1979-04-05
Abstract: A drive circuit (10) for one or more inductive loads (30, 62) provides rapid actuation and deactuation in response to a control signal (E1), and includes a boost coil (12) which is pre-energized preparatory to the actuation of an inductive load (30). Each load (30) has an associated switching circuit which responds to an actuation signal to receive current from the pre-energized boost coil (12). The switching circuit responds to a deactuation signal by maintaining a relatively high voltage (Vz1) across the inductive load in the transition from its actuated to deactuated states to rapidly decrease the current (I1) through the load and speed deactuation. Switch 16, closed to pre-energize the coil 12, is opened at the instant control E1 turns on switch 34 thus giving a high supply voltage EA, limited by zener 26. Molding current to the load 20 may pass via a diode (58 Fig. 2 not shown) with an isolating diode (59) then required also. <IMAGE>
