Abstract: 925,436. Valves. EWERS & MIESNER HARTGUSSWERK UND MASCHINENFABRIK G.m.b.H. Nov. 7, 1961 [Nov. 8, 1960], No. 39906/61. Class 135. A valve for controlling the flow of air into or out of a shelter, which is closed in the event of an explosion, comprises a housing 1 having inlet and outlet ducts 2 or 3 formed with valve seats 10, 11 respectively. Valve closure members 8 and 9 are mounted on the ends of a bell-crank lever 7 pivoted on a shaft 6. The valve members are normally in the position shown when air flows through the valve but in the event of an explosion, the rush of air into the housing acts on the valves to cause closure of one of the valves and the suction created by the subsequent outflow causes the valves to rock and open the one valve and close the other valve. The valve members are provided with studs 18, 19 one of which carries a weight 20, dependent on the direction of normal flow through the housing such that, as shown, with no flow the valve 8 would be closed and normal flow causes the valves to assume the position shown. The valves may be actuated manually from outside by rotating shaft 6 which causes an arm 12 to close one or other of the valves. This closure may be locked. Alternatively, a second shaft may be provided for the manual actuation.

Title: Battery charging systems

Filed: 1972-09-01
Abstract: 1444723 Automatic voltage control LUCAS ELECTRICAL Ltd 14 Aug 1973 [1 Sept 1972] 40614/72 Heading G3R An alternator is controlled by a voltage regulator which varies the current in the alternator field winding. Two freewheel paths are connected across the field winding, one of the paths being disconnected if the alternator voltage becomes excessive, to protect the circuit from damage due to high currents or voltage surge. As shown, a battery 16 is charged by an alternator 11 controlled by a known voltage regulator circuit including a switching transistor 32 connected in series with field winding 30 and normally closed contacts 33. When the transistor 32 is off, current can still flow in the winding 30 by way of a freewheel diode 34. If the battery should become disconnected, the impedance presented to the alternator rises, causing an increase in output voltage and prolonged turn off of transistor 32. High current will flow in winding 30 and diode 34 resulting in possible voltage surge and circuit damage. To prevent this, a Zener diode 39 is connected in series with a relay winding 38 across the alternator output, so that high output voltage energizes the winding 38 which opens contacts 33, thus breaking the freewheel path through diode 34. Current now flows through a second freewheel path comprising diode 37, Zener diode 39, winding 38 and diode 34. This path rapidly dissipates the energy stored in winding 30 and prevents voltage surge. Contacts 33 are reclosed when the output voltage falls below a value sufficient to break down Zener diode 39. Alternative freewheel circuit paths including switching transistors or a gate controlled switch are also described, Figs. 2-5 (not shown).

Abstract: 1528695 Automatic control L SCHULER GmbH 5 Oct 1976 [13 Oct 1975] 41296/76 Heading G3N In a control system for a press, a digitally coded signal corresponding to the position of the press drive is summed with a signal dependent upon the stroke rate of the press, to control the initiation and/or termination of operations related to the press. As shown, the stroke rate is sensed by tachometer IS whose output passes via A to D converter 16 that provides a correction proportional to the stroke rate or the range that the rate falls in to summer 6, which also receives the coded signals from press position generator 5. The summer output is decoded, amplified and sent to pulse distributer 9. Each output of the distributer is connected via amplifier 10, which includes a store, to a regulator 11 which controls the transfer, mechanization, automation and/or control of a tool of the press. The output of amplifier 8 and the coded signal from generator 5 are also supplied to monitoring circuit 12 that deactivates amplifier 10, turns off the press drive motor 4 and operates an optical or audio fault indication 13 if an error occurs in coding or decoding, or if control pulses from amplifier 8 are missing. The press may be used for perforating, punching, cutting and/or shaping.

Abstract: 924,685. Accelerometers. GENERAL ELECTRIC CO. Dec. 7, 1959 [Dec. 12, 1958], No. 41513/59. Class 40 (1). Motion-sensing apparatus comprises a mass supported in a casing by a resilient spring capable of twisting and thus resisting the rotational motion of the mass and preventing substantial movement of the mass in all other planes, the moment of inertia of the mass and the associated damping means being so chosen that the mass will sense acceleration below a predetermined frequency and velocity above that frequency. In Figs. 1 the device comprises an inertial wheel 5 resiliently attached to the top of a cylindrical chamber 7 by means of a torsion spring 8. The chamber is enlarged to form an accurately-dimensioned annular space 6 around the wheel, and the whole is filled with a fluid of known viscosity, so that angular acceleration about a vertical axis will produce a known angular deflection of the wheel relative to its housing. The underside of the wheel is attached to a shaft 10 which is journalled in ball bearings and carries a coil 13b. The latter moves in the field of a permanent magnet NS and constitutes a tachogenerator giving an output proportional to the angular velocity of the shaft. Below the resonant frequency of the suspension the voltage output will be proportional to the rate of change of angular acceleration of the instrument, but above the resonant frequency the output will be proportional to the rate of change of angular velocity. The coil-former and inertia wheel may be one and the same, in which case the fluid-damping may be supplemented by a further rotor and magnet to provide electromagnetic damping (Fig. 2, not shown). Both the permanent magnets may be replaced by electromagnets. The shaft may be supported by crossed springs or torsion bars instead of ball bearings. The device can be mounted on a stabilized platform in space, and the output signal is then used to operate a stabilizing servo-system.
