Title: Coin operated locking device
IPC: G07F17/12
Filed: 1974-11-01
Abstract: 1465124 Coin operated locking device K SCHWIZER AG 1 Nov 1974 [19 Nov 1973] 47307/74 Heading G4V A coin operated locking device has a channel 3, a stationary lock cylinder 10 and a rotor 13 rotatable by a key which can be removed only in the locked position of the rotor. At the free end of the rotor there is rigidly mounted an integral part consisting of bolt 11, lever 14 and projection 15. A catch pin 23 is mounted in the rotor and is biased radially outward by spring 22. A catch pin 19 can project from cylinder 10. In its outer position pin 23 locks the cylinder 10 and the rotor together. In operation a coin is inserted at 4, on the inside of door 2, and comes to rest against pin 17 and pin 19. It pushes pin 19 inwardly which in turn moves pin 23 inwardly to release the rotor for turning by the key. As the key is rotated bolt 11 moves to a locking position. A shoulder 16 on lever 14 moves the coin to the outside of pin 17 where it rests on projection 15. Unlocking allows the coin to drop from the channel for return to the user. Unlocking by a master key is facilitated by a slot 25 in pin 23. A nose on a master key engages in the slot to move the pin to a release position. The bolt could move in a straight line by provision of teeth on the rotor.

Abstract: 1,013,064. Zone-melting. SIEMENS & HALSKE A.G. Dec. 2, 1963 [Dec. 3, 1962], No. 47394/63. Heading BIS. In the production of a monocrystalline rod of germanium or silicon by zone-melting or crystal-pulling, a low lattice dislocation (e.g. 5000/cm.<SP>2</SP>) is produced in the rod by passing a current between the growing rod and the solidifying melt, preferably from the melt to the rod. The current density may be 100 A./cm.<SP>2</SP>. An alternating current may be superimposed on the direct current. The rod may have a diameter of 10À5 mm., the speed of pulling may be 2À5 mm./minute, and the pulled rod may be rotated at 60 r.p.m. As shown, a rod 2 is melted by an induction coil 8 to produce a molten zone 3, and a rod I is solidified from molten zone 3. Passage of a current in direction 7 produces a concave solidifying surface 5 which moves in direction 4.

When a signal is generated by circuit 18 indicating wheel lock, needle valve 66 opens progressively to allow a chamber 56 to be evacuated to an engine intake manifold 16, interconnected diaphragms 58, 57, 50 being moved upwardly by the differential pressure across diaphragm 57 so that a suction valve member 53 is caused to seat thereby closing off chamber 33 of the valve 24 from the vacuum source, further movement of the diaphragm causing a valve member 48 to be unseated to allow air to pass through a filter 43 to the chamber 33, the differential pressure across the diaphragm 35 causing valve stem 36 to move the ball valve 29 to be seated and cut off communication between the master cylinder 10 and the rear wheel cylinders. Control circuit 18 comprises wheel speed sensors 70, 71 and 70<SP>1</SP>, 71<SP>1</SP> which feed signals to pulse processors 72, 72<SP>1</SP> the outputs of which are integrated at 73, 73<SP>1</SP>, differentiated at 74, 74<SP>1</SP> and fed to a common OR gate which generates a signal when the signals from either rear wheel exceeds a predetermined value. The signal is compared with a constant voltage from a source 77, amplified at 78 and fed to the solenoid 65. A fail safe circuit 79 shutting down the amplifier if it fails and a temperature compensator 80 may be provided the latter correcting for the temperature of the solenoid. A memory circuit 82 connected to a fluid pressure sensing device 22 and to the amplifier 78 causes fluctuations of fluid pressure to be suppressed to an optimum level.
