Abstract: 1,104,795. Control of D.C. motors; rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 Oct., 1964 [29 Oct., 1963], No. 42646/63. Headings H2F and H2J. [Also in Divisions G3 and H3] A D.C. motor is supplied from an A.C. source through rectifiers, preferably solid stage type, at least one of which is controllable and is switched on and off at variable intervals to keep the average current substantially constant. As shown, two thyristors A, B are used in a traction motor circuit. Initially, A conducts for one half cycle and is off for several, during which the motor current decays through diodes C, D; B is then fired for one half cycle, and so on. The non-conducting period is progressively shortened as the motor accelerates, by detecting the current through a reactor L which saturates at the designed accelerating current which is thus kept substantially constant. Finally A and B conduct on every half cycle to provide normal full wave rectification. In an alternative arrangement A only is initially fired at regular intervals (e.g. on every fourth cycle) but the instant of firing in the sine wave is advanced until it conducts for a whole half cycle, whereupon the procedure is repeated with B followed then by progressive shortening of the interval as before. In a further alternative arrangement, (Fig. 5, not shown) B is replaced by a normal diode, switched in by a contactor when A reaches the point of firing every half cycle; A then reverts to its initial condition and repeats the accelerating procedure. This arrangement is used for two motors, the controlled rectifiers for each operating on alternate half cycles. When full speed is reached, A may be shunted by a normal diode so that A can be short time rated. A suitable circuit for controlling the firing of the rectifiers is shown in Fig. 9. Rectified A.C. is clipped by Zener diode ZI to produce spikes at twice mains frequency. T1 is normally biased off via resistors R 1 , R 3  such that the spikes at Z1 are insufficient to turn it on. T2 is on, T3 is off and the base voltage of T4 is free to rise negatively. Due to the feedback action of C3 the voltage on C2 rises linearly and the emitter voltage of T4 follows. This emitter voltage is fed back via R13 to T1 base, tending to overcome the hold-off bias. At a critical value, T1 turns on, T2 turns off and the feedback via C1 and R8 ensures rapid change over. The output pulse from C1 via R9 turns on R3, discharging C2, bringing base and emitter of T4 to zero. This switches off T1 and the cycle repeats. The sawtooth waveforms can be adjusted to span any integral number of half cycles by means of variable resistor R3. The output from T4 is mixed with a comparator output (comparing motor current with a reference) and the result used to control the on/off periods of a trigger circuit T5, T6 similar to T1, T2.

Abstract: 1,204,692. Static inverters. BROWN, BOVERI & CO. Ltd. 20 Sept., 1967 [22 Sept., 1966], No. 42835/67. Heading H2F. An inverter (e.g. a thyristor single phase bridge inverter) of the known type illustrated in Fig. 1 (not shown), wherein a capacitor resonates with an inductive load containing ohmic resistance (e.g. a motor or induction furnace) at a frequency which is fed back to the thyristors control circuit in a known manner (not described) whereby the output frequency of the inverter equals the resonant frequency of the resonant circuit, including the load, is modified by the connection of a capacitive quadripole network between the inverter and the load. In Fig. 2 the network comprises a series capcitor 10 and shunt capacitor 11 the latter resonating with the inductance 8 of the load; this arrangement increases the commutation voltage (Fig. 6, not shown) and facilitates operation at higher frequencies. By transferring C10 to the dotted position, e.g. by a selector switch as Fig. 4 (not shown), the voltage. to the load is stepped up. By making the capacitors variable the load voltage can be controlled. By using three capacitors and a selector switch (Fig. 5, not shown) the load voltage may be stepped up after switching on.

Abstract: 985,783. Boring earth &c. F. ZIMMERMANN. Dec. 13, 1961, No. 44616/61. Heading E1F. [Also in Division B4] A transportable drill comprises a chassis 5, a percussive hammer 1, an extensible drill rod 7 carrying the hammer, a motor 2 rotating the rod and hammer, a slide 12 supporting the motor, rod and hammer, a motor 4 for moving the slide along a guideway 3, and mechanism 22, 26 for lowering the guideway on to the chassis for transport. The motor 4 drives a chain 14 (Fig. 7) connected to the slide and to a cable 15 also connected to the slide. The motor 2 is connected to the slide by springs 18 and carries a switch 21 operated by stops 19, 20 fixed to the slide. As drilling proceeds the springs compress to engage the switch with the stop 20 to start the motor 4 which lowers the slide until stopped by the switch engaging the stop 19. The springs then compress again to repeat the feed process. A compressor 6 supplies air to reservoirs formed in the chassis frame and joined by a hose to a connector 102 sliding in the head 101 of the hammer. Air entering the hammer passes through bores 128 to lift a slide valve 130 and pass through ducts 112 to the space 133 to raise the hammer piston 108. At the beginning of the upward movement of the piston some air from the space 134 above the piston passes through ducts 113, 118, 119 to a space 120 from whence it is discharged through bore 121 in the bit 116 and about the bit to clear debris from the hole. As the piston reaches the top of its stroke the pressure of the air above the piston lowers the valve 130 so that air from the bores 128 flows through the valve to the space 134 to drive the piston downwardly and to exhaust some air through the ducts 113. As the piston nears the bottom of its stroke air passing through ducts 112 lifts the valve 130 to start the upward stroke of the piston. As the hammer is removed from the hole the connection 102 moves upwardly relative to the hammer, and a pin 125 is raised by a spring 132 so that air flows through both the bores 124, 128 and valve to interrupt reciprocation of the piston, the air passing through the ducts 113 for discharge.

A valve device for connecting a fluid pressure generating device (not shown) to two fluid pressure storage devices (not shown) comprises a valve body 10 having first and second valve ports interconnected by a valve bore 11, a third valve port 12 between the first and second valve ports, two pistons 13 urged by spring means 14 against stops 15, passages 16 past the pistons, and non-return valves 17 in the passages. As used on vehicle braking systems the bores 11 are connected to liquid pressure accumulators and the port 12 is connected via an unloader valve (not shown) to a liquid pressure pump. Liquid is delivered to both bores 11 and hence to the accumulators, and any acceptable amount of leakage from the conduit system leading to the port 12 will cause the two pistons to move towards each other until the pressure on both sides of the pistons are equal. If a leak develops in either one of the liquid pressure accumulators the piston corresponding to the other accumulator moves inwardly. The amount by which the piston moves is dependent on the rating of the spring 14. It may cover the port 12 and orifice 18 or it may be excessively loaded by the spring 14 to prevent such a closure. A warning device is fitted to the valve which provides a light signal or audible alarm when the pressure of fluid between the pistons 13 falls to a predetermined minimum.
