Title: Coin Selector
IPC: G07D5/08
Filed: 1966-12-16
Abstract: 1,170,417. Testing coins. CROUZET. 16 Dec., 1966 [31 Dec., 1965], No. 56430/66. Headings G4V and G4X. In a coin-testing apparatus, a coin P to be tested varies the impedance of an inductor E 1  in one arm of a bridge circuit, whereby the output from the bridge is used to control means directing the coin into alternate channels for " good " or " bad " coins. Initially, a standard coin. is placed in the inductor E 1  and resistor R 3  adjusted to produce a null output on a differential or balanced amplifier 3, Fig. 1. Resistor R 3  may be replaced by a second inductor containing a standard coin p. In a third arrangement, the bridge circuit contains inductors E 1 , E 2  in two arms, subjected to alternating magnetic fields by primary windings E 1 <SP>1</SP>, E 2 <SP>1</SP>. A standard coin p is located in the inductor E 2  by adjustable members 4, 4<SP>1</SP>. Referring to Fig. 8, the coin P is brought to rest by stops 9, 12. In this position, the light to detector 16 is interrupted to produce an output applied to AND gates 25, 26. The output from the bridge is applied to amplifier 3 and then rectified and shaped to produce a signal x or x according as the coin is " good " or " bad." This signal is applied to AND gate 25 and through a switching unit 27 to apply the complementary signal to AND gate 26. The appropriate flip-flop 31 or 35 is operated to energize the solenoid 11 or 14 and withdraw a stop 9 or 12. As the coin falls down the channel 8c or 8d the detector 18 or 19 emits a pulse to reset the flip-flop 31, 35. In addition, the detector 18 pulses a counter 33 registering the total number of " good " coins received. A manually-operable button is provided for retracting the stop 12 whereby jammed coins may be released, Fig. 7 (not shown). In an alternative arrangement, Fig. 13, the coin P is tested during movement down a guide channel 8. As the coin enters the inductor E 1 , the detector 16 applies a signal to AND gate 25, a second signal being applied via the amplifier 3 if the coin is acceptable. Flip-flop 31 operates to energize solenoid 11 and move deflector 9 to the dotted line position. As the coin passes detector 18 a signal is generated to reset flip-flop 31 and step counter 33.

Abstract: 1302399 Aerials NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 30 Nov 1970 [28 Nov 1969] 56880/70 Heading H4A In an aerial a primary radiator 12, which emits plane waves, is associated with a spherically shaped main reflector 1 via plane reflectors 10, 9, a parabolic reflector 8, and a sub-reflector 4. The sub-reflector is disposed nearer the main reflector than is the centre 5 thereof, and is shaped to compensate for spherical aberration. The focus of the parabolic reflector 8 is co-incident with the centre 5. The sub-reflector 4 may be tilted about the centre 5, both upwardly and downwardly and from side to side. At the same time, the plane reflectors 9, 10 may be moved parallel to themselves, so that the sub-reflector remains fully illuminated. In this way, the beam from the main reflector 1 is deflected so that, for example, a satellite may be tracked. Mechanisms for tilting the sub-reflector and for moving the plane reflectors are described (Figs. 4, 5, not shown). When tracking, error signals may be applied to ' control said mechanisms in unison (Fig. 6, not shown). In a second embodiment, two primary radiators are each independently associated with a single spherically shaped main reflector by means of respective plane reflectors, parabolic reflectors, and sub-reflectors (Fig. 13, not shown). In a third embodiment, aperture blocking is avoided by off-setting the primary radiator, the plane reflectors, and the parabolic reflector from the beam radiated by the spherically shaped main reflector (Fig. 14, not shown).

Abstract: 1327998 Sanitary closets; sewerage systems CHRYSLER CORP 21 Dec 1971 [21 Dec 1970] 59373/71 Heading E1C A sewage disposal system for separating sewage from a flush medium having a specific gravity less than that of water, e.g. 0.85, and which does not mix with water, so that the fluid separates from the sewage by gravity and can be recirculated through the bowl 10 of a sanitary closet or like appliance with minimal loss, comprises a separating tank 16 which has a lower sump portion 20 and an upper portion 22 between which is located a filter 24, the sump portion 20. communicating with the bowl 10 via a pipe 18 and being also connected via a macerator 28 and solenoid valve 30 to a receiving tank 32, a control system being provided in association with the macerator 28 and valve 30 whereby when the level of sewage in the sump portion 20 rises to about the level of filter 24, the valve 30 opens and the macerator 28 is made operative to break up solid matter in the sewage and transfer the sewage into the receiving tank 32. The control system includes a float 60 designed to float on the sewage but to be heavier than the volume of flushing fluid it displaces, and which controls a switch 62. A further parallelconnected switch 68 controlled by a float 66 provides a back-up system, whilst a switch 72 controlled by a float 70 in the tank 32 switches off the circuit controlled by the switches 62, 68 should the tank 32 become full. Sewage received in the tank is pumped by a pump 38 through a solenoid valve 40 into a disposal device, e.g. an incinerator 44, so long as the level in tank 32 is above that of a float 74 controlling a switch 76. The various sewage transfer operations continue for a predetermined time as determined by a time-delay relay controlled by a normally-closed switch 64 operated by the float 60. Flush fluid passing through the filter 24 has to pass through further filters 26, 58, of which the latter is designed to remove bubbles of water in the fluid, before being recirculated through the bowl 10 by an arrangement comprising a pump 48 controlled by a pressure switch 56 on a pressurised fluid reservoir 50, and a closet tank 12 having a valve operated by a handle 14 for flushing the closet or like sanitary appliance.

Abstract: 1343509 Vapour or steam engines; valve gear STEAM POWER SYSTEMS Inc 22 Dec 1971 [31 Dec 1970] 59773/71 Headings F1K F1M and F1Q In a vapour engine, for example a steam engine, the vapour inlet valve to the engine expander is a fluid operated valve operated by the same working fluid as the engine, in a liquid phase. The expander may be a reciprocating piston and cylinder type and the inlet valve may be a poppet valve. As shown the engine includes an inlet valve actuating distributor 36 and an exhaust valve actuating distributor 37 for operating the inlet and exhaust valves of the cylinders. The two distributors are operated off the crank shaft 15 as indicated diagrammatically by dashed lines 38. High pressure water from the feedwater pump 25 is fed through a line 39 to the distributors. Timed pulses of high pressure water are supplied to the inlet and exhaust valves through lines 40 and 41 respectively to open and close the valves hydraulically in timed sequence. If reversal of the engine is desired, rephasing of the exhaust valve action is readily achieved by making a centre manifold axially movable within the distributor body. Rotation of an inlet valve centre manifold (not shown) by a control lever varies the deviation of steam admission to each cylinder by varying the operating cycle of the associated inlet valves. It is stated that high speed solenoid actuated valves can be employed between the engine steam valves and the source of high pressure water. The invention is applicable to vapour engines using a working fluid, other than water. Organic fluids and mercury vapour are referred to.

Title: Electric starter motor circuit
Inventor: HOLLAND-MORITZ HANS
Filed: 1968-12-18
Abstract: 1,219,620. Starting prime movers. KOMBINATVEB FAHRZEUGELEKTRIK RUHLA. 18 Dec., 1968, No. 60217/68. Heading H2H. An electric starting motor for an internal combustion engine comprises a device for automatically disengaging the starting shaft when the ignition rotation speed of the engine has been reached. In the arrangement shown, the starting motor 1 has a shunt winding 2 in parallel with the armature 3 and series winding 4. In operation, closure of a starting switch 10 causes current to flow from a battery 11 through a capacitor 9 to a relay 7 which closes contacts 8. Current now flows through a further relay 13 to close a starting magnet switch 14. At the same time, the starting shaft, which includes a longitudinally displaceable meshing pinion, engages the engine and a high current flows in the armature circuit. The resulting voltage drop across the winding 4 switches on a transistor 6 to maintain current in the relay 7. As the speed builds up, the current in the armature falls, and hence the bias on the transistor is reduced until the current through it is insufficient to hold the relay 7. The contacts 8 and 14 now open and the starting pinion is disengaged.
