Filed: 1977-09-01
Abstract: 1535636 Article-receiving devices J C F KAUFMANN METALLWARENWERK 1 Sept 1977 [24 Nov 1976] 36572/77 Heading A4T [Also in Division E2]  A bullet-proof cash transfer device e.g. for a bank comprises slidable or pivotable bullet-proof doors 4, 5 on opposite sides of an intervening space, the doors 4, 5 being so arranged to operate that either one can be opened only when the other one is closed. With a front door 5 open, articles may be inserted on to a conveyer belt 3 within the space, the rear door 4 being locked in closed position by a bolt 14 slidably mounted in guides 15. An operator behind the rear door 4 then depresses a footplate 13, pivoting a lever 11 and pulling down pulleys 10 attached to the lever 11 by a linkage, so that a cable 6 attached to the doors 4, 5 at points 7 causes the door 5 to rise. When the lever 11 has been fully depressed it engages a switch 19, actuating an electromagnet 18 to move the bolt 14 against a spring 17 so that the door 5 is locked and the door 4 is freed. On releasing the lever 11, the door 4 falls under gravity as the pulley 10 rise, and articles on the conveyer 3 may be withdrawn. The lever 11 may be replaced by an electrically operated system, Fig. 3 (not shown).

The analogue/digital converter is preferably a coarse and fine dual ramp digital voltmeter with coarse and fine counter operating shift registers to feed the 12 bits after expansion to 16 bits to the' filter of Fig. 5 which comprises registers R1-R6 receiving combinations of the coded signals multiplied by the coefficients A5, A3, A1 and A0 such that at time T -5  the contents of register 6 are # E . The filter is connected to a compressor 4 which transmits the PCM signals to an expander 5 in the receiver. At the receiver the signals are transformed in a filter similar to the filter of the transmitter except since in this case S. = 0 there is no multiplication by A 0 . the signals are simultaneously fed to a delay. The delay and filler feed a second filter and delay so that output signals are obtained at four times the frequency of the transmitted coded signals. The PCM signals are converted to # pulse modulated form by subtracting successive code groups and fed to converters 7 one of which is shown in Fig. 7 which using gates P1-P6 enabled far differing numbers of clock pulses deliver a number of pulses corresponding to their weights to an OR gate P7. The gates P7 are connected to integrators to give an output, the mean value of which corresponds to the analogue input to the transmitter.

Abstract: 925,544. Heat treating metals. TO-A KAKO KABUSHIKI KAISHA. Nov. 6, 1959 [July 22, 1959], No. 37777/59. Classes 72 and 82. [Also in Group XI] A piece of metal 4 to be heat treated is connected to one pole of a generator 5 and the heating circuit is completed through a bed 8 of conducting or semi-conducting particles, e.g. of carbon or carbon silicide, fluidized by a stream of compressed air or inert gas such as nitrogen which enters an inlet 3 and passes through a micro-porous tile 2. The generator 5 is connected through a regulator 6 and switch 7 to the fluidizing chamber 1 if this is electrically conducting, or to one or more electrodes immersed in the bed 8 if the chamber 1 is of insulating material. It is stated that the heating effect is greatest at the surface of the metal 4 owing to the high contact resistance between the particles and the metal, but can be varied by means of the regulator 6. The piece of metal 4 may be rotated about its longitudinal axis during heat treatment. In an alternative arrangement (Fig. 2, not shown) a wire to be heat treated is passed through opposed openings in the side wall of the chamber provided with packing to prevent leakage of the particles. Two or more such chambers may be employed in tandem with one phase of a polyphase supply connected to each chamber. The method may be applied to heating or tempering wheels and to continuously annealing piano wires, copper rods or brass plates.

Title: Improvements in or relating to Dispensing and Heating Apparatus
Inventor: SMITH PETER HAROLD
IPC: G07F9/10
Filed: 1966-08-24
Abstract: 1,197,176. Dispensing and heating apparatus. MICROTHERM Ltd. 24 Aug., 1967 [24 Aug., 1966], No. 37945/66. Heading A4T. [Also in Divisions H2 and G4] A food dispensing and heating apparatus is manually operable so that the choice of push button or code dialled selects both the particular one of its magazines from which an article is dispensed and the length of time for which it is heated. For four vending magazines, MA to MD, a selection circuit is shown in Fig. 1 before operation. The coin acceptor CA accepts a coin, briefly closing contacts VCC, so that on operating one of the push buttons PBA to D, the anticoincidence relay RE closes contacts RE1 to energize the solenoid CRS to reject a further coin, and opens contacts REA to RED so that further button pushing has no effect. Then one of relays RA to RD that is also energized, R.A. for example, closes contacts RA1 and 2 to maintain a complete circuit and operates the release mechanism of its corresponding magazine MA. The released article may be automatically carried into the oven, where closing the doors closes contacts LSD1 and 2 in the power supply circuit (Fig. 2) for the magnetron generator and for the timing circuit. A time delay relay maintains contacts DT1 open until the magnetron filament has been heated. Thereafter the starter switch SPB, operated manually or automatically when the oven doors close, energize relays CR and MC, closing contacts MC1 and 2 to energize the transformer HTT and bridge rectifier BR. In the timing circuit, Fig. 3 (not shown), a capacitor changes up until after a time determined by the original choice of switch PBA via relay RA and contact R4A, one of four contacts R4A to D in parallel, bringing its associated resistor of a particular size into the circuit, it fires a thyristor to briefly energize the timer relay RT (not shown) to end the sequence of operations by closing contact RT2 in the timer circuit to discharge the capacitor, and opening contacts RT3 and RT1 in the power supply and selection circuits respectively. Safety devices include thermally responsive contacts MT that open if the oven overheats, a limit switch to prevent the cycle beginning if the doors close without an article in the oven, and a monitoring device to interrupt the power supply if the article has inappropriate electromagnetic impedance.

Filed: 1976-09-14
Abstract: 1516601 Hoist control systems MANITOWOC CO Inc 14 Sept 1976 [23 Oct 1975] 38030/76 Heading B8B A power lowering system for a hoist drum of a load lifting device comprises an engine 12 which drives the drum 10, 11, through a torque converter 15 and a hydraulic motor 40 which can also drive the drum and which is fed with fluid along supply and return lines 41, 42 by a pump 43 driven by the engine. During lowering the torque converter 15 is rendered inoperative and the drum 10, 11 is driven by the hydraulic motor 40. If the load is heavy the torque on the drum 10, 11 drives the hydraulic motor 40 which acts as a pump. The increase in pressure in the return line 41 acts through a restriction 52 on an actuator 51 connected to the actuating lever 19 of the torque converter. The converter then drives in the hoist raising direction to slow the lowering. The two hoist drums 10, 11 are driven selectively by hydraulic clutches 28 actuated by control levers 22. The selected drum is driven in a lifting direction solely by the engine via the torque converter 15. The torque converter is preferably of the variable or modulated type although a non- modulated type may be used in conjunction with a modulated clutch. The boom hoist drum 60 of a crane in which the hoist drums 10, 11 are front and rear cable drums is similarly controlled. The boom hoist drum is driven by the engine 12 through a torque converter 63 for raising and lowered by a hydraulic motor 65 with supply and return lines 67, 68. During lowering any pressure build-up in the return line actuates the torque converter 63 to drive in the raising direction. A restriction 81 is provided between the return line 67 and the torque converter actuator 74 to prevent hunting.
