Title: Force responsive devices
IPC: G01L9/00
Filed: 1972-12-07
Abstract: 1348969 Measuring force electrically; pressure gauge liquid level indication YOKOGAWA ELECTRIC WORKS Ltd 7 Dec 1972 [29 Dec 1971] 56504/72 Headings G1H, G1L, G1N, G1W Apparatus for measuring force by producing a corresponding displacement of a flexible tube comprises a mechanical assembly for amplifying the displacement and for ensuring a linear relationship between displacement and force wherein the bending tube Fig. 2 is fixed at one end and attached to a deflection rod and a loading arm at the other end, the test force F being applied to the loading arm in a direction parallel to the axis of the tube and rod and at a distance approximately half the length of the tube from the centre of the tube. It is shown that under these conditions the stress along the tube is constant and the effects of force components in other directions are negligible. In one embodiment Fig. 9 for measuring a differential pressure, a sealed capsule 4 consist-  ing of two diaphragms 43, 44 linked by a member 45, is subjected externally to a first fluid pressure in a chamber 30, fed in at 31, and a second fluid pressure in chamber 20. The resulting displacing force on member 45 is transmitted via loading arm 8 to bending tube 6 and deflection rod 7. The upper end of tube 6 is fixed by its flange 61. At the upper end of deflection rod 7 is located a differential inductance transducer 9 comprising two similar coils 96, 97 wound on the I - member of an E + I core assembly. A short-circuited copper ring 98 surrounding the I - member is attached to the rod 7, whereby deflections of the rod by the differential pressure sensed by the capsule 4 displace the ring 98 to differentially vary the inductances of coils 96, 97. Further electrical circuitry is located on printed circuit boards 15, 16. In another embodiment Fig.13 for measuring liquid level, a member 18 is supported by a hook 181 and flexure link 10c from the loading arm 106 of a bending tube 6 carrying a deflection rod 7. The apparent weight of the member 18, when it is partly submerged in the liquid, depends on the liquid level and determines the force W which produces a corresponding displacement of the free end of the rod 7.

Title: Static card reader and control system for access apparatus
IPC: G07C9/00
Filed: 1973-12-10
Abstract: 1446094 Magnetic card systems RUSCO INDUSTRIES INC 10 Dec 1973 [4 Jan 19731   57189/73 Heading E2A At least one spot magnetized card 16, 20 is releasably supported so that a plurality of electromagnet sensors each having a coil 44 wound on a core detent such spots, a switch 22 being actuated by positioning of the cord for a voltage to be momentarily supplied across the coils and respective series resistors 46 the outputs therefrom passing to a gate network 50 so that a pulse is produced for operating access apparatus. Two cards 16, 20 are inserted relative to the sensors such that the magnetized spots of the cards do not coincide with each other; upon operation of the switch 22, a circuit 30 for removing transient spurim signals, e.g. a flip-flop, causes a pulser 32 e.g. a one short trigger circuit to operate an electronic switch 48 and provide a short duration input to a logic circuit 34 e.g. a flip-flop, which beforehand provides a logic "1" output. If and only if the spots are magnetised in the correct direction, and the spots coincide with the sensors, the gate network 50 provides a logic "1" output to the circuit 34 which causes the output thereof to be a logic "0" signal to actuate a pulser 52 similar to the pulser 32; an AC switch 60 is actuated to provide power to operate a solenoid 62 of the access apparatus. Alternatively power could be supplied to retain the access apparatus in the locked condition and unlocking occurring when the power is removed by the A.C. switch. Differently coded cards may be used to actuate the access apparatus at different times, a switch 80 switching out either or both of two sensors so that the cards which are "deficient" in magnetised spots corresponding to one of these sensors can be selectively used for such actuation. Similarly a card inserted in an "entrance" detecting apparatus can be recorded by operation of two electromagnets 100, 102 for demagnetising a spot and/or magnetising a non-magnetised spot, the electromagnets being coupled to a voltage doubler, Fig. 3 not shown, connected to the power source. The recorded card can then be used in "exit" detecting apparatus (e.g. at a parking lot) which then records the card for subsequent "entrance" detection.

Title: Apparatus for enabling the use of machines for providing  services or goods
IPC: G07F7/00
Filed: 1973-12-11
Abstract: 1457447 Token-controlled machine AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE ANVAR 11 Dec 1973 [11 Dec 1972] 57429/73 Headings G4V and G4T To use a machine, a token (Fig. 6) having a peripheral array of tongues 49, 50 is inserted into a device controlled by the machine, and during the period of use the token is incrementally rotated, e.g. by a time-responsive drive, to bring a succession of the tongues into line with a reciprocating knife, which severs such tongues, so that at the end of the hire period, when the token is ejected from the device, it carries n fewer tongues, n being proportional to cost of use of the machine, e.g. the period of hire. The machine may be a car, a motor boat or a goods (e.g. petrol) dispensing machine. The embodiment described is for use with a hire car. Tongues 49 alternate with tongues 50 around the periphery of the disc token and are of lesser thickness than tongues 50, Fig. 7 (not shown). The resulting alternating level of tongue opacity is sensed by a light/photocell combination in the device as a check on token authenticity. A cassette (Figs. 11-14, not shown) is provided for loading two tokens into the device. Inserting a loaded cassette closes a switch which energizes a motor coupled to a drive element for incrementally rotating the token. A knob is manually rotatable for moving the drive element through a hole in the cassette to engage the token and for moving a cassette retaining finger across the entrance to the slot into which the cassette has been loaded. The token is rotated to check that it has at least three tongues and to align the first tongue with the knife. A light and a camera are now energized to photograph the cassette, a face of the token visible through a hole in the cassette, a clock, a day and year indicator and a mileage recorder, Fig. 3 (not shown). The vehicle starting/ignition circuits are now enabled. During the hire period, electronic pulses are counted and used to energize the token-stepping motor. After each angular step, a tongue is severed by the knife, which is operated by a crank on the output shaft of an electric motor. To terminate the period of hire, the vehicle driver operates the manually-rotatable knob to disengage the drive element from the token, to unblock the cassette slot, to energize the camera, to zeroize the counters and to energize a solenoid for ejecting the cassette from its slot, this last step only taking place, however, if the vehicle's windows are closed and the handbrake applied to close corresponding switches in the solenoid circuit. If, during the period of hire, the light/photocell combination, detects that the number of tongues on the ticket has dropped to three, a light is flashed to warn the driver that the vehicle will soon stop. If the driver does not then stop the vehicle within a certain time, the engine is switched off automatically and the camera is operated.

Patent GB-789646-A (GB)
Abstract: 789,646. Ratchet gearing. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 23, 1956 [April. 26, 1955], No. 12331/56. Class 80 (3). A linear motion step-by-step drive of a rod 138 is effected by a plurality of solenoids A, B, C, D energized in sequence and controlling movable armatures 94, 96, 98 and 100. Armature 94 actuates locking fingers 164 which engage with annular grooves 136 on the rod whilst armature 100 actuates coupling fingers 130 engaging the grooves 136. ' When the solenoid D is energized armature 100 is moved upwards against springs 114 to couple the fingers 130 to the rod 138. The fingers 130 are carried by a tube 102 to which the armatures 96 and 98 are attached. If solenoid C is now energized armature 98 is pulled upwards with the rod. Solenoid A is now energized to move armature 94 upwards against springs 172 whereby the cocking fingers 164 engage the rod and hold it whilst solenoids C and D are deenergized and solenoid B energized to force armature 96 downwards together with armatures 98 and 100 to return coupling tube 102 to its original position and uncouple fingers 132 from the rod. Thus one cycle of operations is completed to give a step movement of rod 138 and the cycle can be repeated for subsequent steps by means of motor-driven cam-operated switches until the desired position of rod 138 is obtained. Reversal of the sequence of operations will reverse the direction of movement of the rod which can be carried out by reversing the direction of the driving motor for the cams.
