Abstract: 1,151,652. Fluid-pressure servomotor systems. BELL AEROSPACE CORP. March 7, 1967 [March 14, 1966], No. 10634/67. Heading G3P. A redundant hydraeric control system includes a plurality of channels each having a servovalve 12 or 107 to supply fluid to an actuator in response to input signals, sensor means to provide an information signal indicative of the operational status of the servovalve, logic means 22, 79 or 103 for receiving the information signals, shut-off means 24, 81 or 104 to disable a failed servovalve, and valve means 41 to open conduits 77, 78 and 102 to reset shut-off means 24, 81 and 104 and to open conduits 82, 106 and 121 to energize the logic means and the servovalves in a predetermined time relationship. The application of fluid to conduits 77, 78 and 102 by initial movement of the valve 41 causes orifice pistons 151, 152 and 153 to shift to the right closing ports 154, 155 and 156 and opening ports 157, 158 and 159. The lines 82 and 106 supplying the servovalves are thus connected to the logic devices 22, 79 and 103 which connect one of the conduits 77, 78 or 102 to a return R 1  or R 2  in the event of disagreement between the sensors. Further movement of the valve 41 connects hydraeric sources P 1 , P 2  and P 3  to conduits 82, 106 and 121 supplying the servovalves and restricted orifices 84, 86, 109 leading to the bores in the pistons 151, 152 and 153 which are thus maintained in operative position when final movement of the valve 41 disconnects the sources P 1 , P 2  from the shut-off means 24, 81 and 104. These two sources are each connected through a solenoid-actuated valve 66 and a restriction 62 to a chamber 63 containing a drive rod 71 for actuating the valve means 41. Non-return valves, such as 68, permit rapid return of the valve means by a spring 125. The second channel of the system may operate on either a force-sharing or a standby basis while a third channel provides a monitoring signal.

Abstract: 1,175,095. Portable warning device for mines. R. HUBNER. 8 March, 1967 [26 May, 1966], No. 10855/67. Heading G5J. A portable warning device for use in mines comprises an accumulator 2, an oscillator 3, an amplifier 4, a diaphragm type sound producer 5 including a diaphragm 7 sealed in a window opening in a wall of casing 1, and a switching unit 6 connected to a key-operated switch 8 or plug-in connector. The various components are operated above their intrinsically safe levels of voltage and current to produce an adequate sound output, but the switch or plug-in connector is electrically protected by limiting devices. A grating 14 protects diaphragm 7 from external damage. In Fig. 2, the oscillator 3 is a Wagner's hammer actuated mechanically by the sound producer 5, and a variable output switching transistor TS2 is included in the oscillator circuit. In Fig. 3 (not shown) the oscillator is a transistorized multivibrator. In either case, oscillator 3 is connected to a second low frequency multivibrator 12. When switch 8 is closed, the parallel switching transistor TS1 conducts and amplifier 4 sends current to the relay coil of sound producer 5, operating diaphragm 7 and opening contacts 13 of the Wagner's hammer so that transistor TS2 is de-energized. Multivibrator 12 acts as an intermittent pulse generator so that an intermittent sound signal is emitted. In Fig. 3 (not shown) the useful load is a loudspeaker (5) and a switching transistor relay (TR) is the final output stage. Multivibrator (3) generates the basic signal frequency and multivibrator (12) generates an intermodulation frequency to produce a warbling tone signal. The accumulators 2 are rechargeable through contact 11 via rectifying diode 10. Parallel leads 9 may be included in the switching unit circuit 6 for operation of the warning device by connection to the shot-firing equipment circuit. The switching unit is protected by limiter resistances 15 and a parallel Zener diode Z. Casing 1 may be provided with a lock and chain to secure it to a mine support.

Filed: 1929-04-09
Abstract: 313,147. Vereinigte Eisenbahn-Signalwerke Ges. June 8, 1928, [Convention date]. Electric operation and control, and by vehicle. - In a point-setting system for shunting yards, a control selector A is connected to a local selector G, assigned one to each of the points except the first, the orders being transmitted from selector A to each selector G ccncerned as each wagon passes an insulated track section or contact, the first two points being controlled direct from the selector A. This selector comprises contact-bars a - - d for individual wagon groups, and bars a<1> - - a<4> connected to relays 1 - - 4 corresponding to the sidings g<1> - - g<4>. Plugs b<1> are used at the bar-intersections to select the routes, and bars a - - d are connected to contacts engaged by an arm sch<1> operated by a notching-relay sch. With the plugs as shown, a circuit is completed from B, relay 2, a<2>, a, sch<1>, back to B, and relay 2 operates to close a circuit B, 2c, relay w1c-, s1f, and s1c. Contact k<4> closes to complete a circuit F, a<14>, k<4>, k<2>, field e<2>, armature m<1>, and a<15>. An alternative control is by hand-lever h<1>. Passage of an axle E over section wla completes a circuit D, a<8>, E, a<9>, relay sla, and a<11>, while relay s1b is closed at section w1b. Contacts s1g and s1b are closed, so that when w1a is free, a holding-on circuit for sla is completed in parallel to s1b. With contacts s1c, s1d both closed, the relay sch is energized by battery B and contacts u1a so that the arm sch<1> is advanced one step. Armature a<6> closes contacts sch<2> to energize relay u<1> which opens contacts u1a to de-energize relay sch but closes contacts u1b for a holding-on circuit for the relay u<1>. Relay 2 in closing also completed a circuit B, 2d, relay f<2>, u2a, and a<18>, relay f<2> acting similarly to relay sch and advancing the local selector G one step. If the setting had been for siding g<1>, the circuit would have been made by contacts 1d and relay w2cto relay f<2>, so that armature a<26> would have acted on one of the pins a<25> to depress it. When the selector G advances. one step, the circuit passes through u<2>, the circuit of f<2> being then broken at u2a and a holding- on circuit completed at u2b. The pins a<25> engage a detent a<27> determine the contacts p2+ or p<2>- in the circuits of the field windings e<3>, e<4> and armature m<2>. The passage of the wagon over the sections w2a, w2b causes the closing of contacts s2c, s2d in a circuit from B to relay t<2>, and this relay moves the detent a<27> on to the next pin. The relay t<2> can also be energized from battery B by a button ht to cancel the next setting of the selector G.
