Title: Alternating current commutator machine
IPC: H02K27/18
Filed: 1923-06-26
Abstract: 221,591. Kostenko, M., and Japolsky, N. June 26, 1933. Alternating-current commutator Machines; commutators and collecting-rings; brush-holders. -An alternating-current commutator machine has the stator windings S, Fig. 1, connected through slip-rings Q to the segments of a commutator K, driven with the rings at a speed proportional to that of the rotor R, the brushes of the commutator being connected through sliprings B to the rotor windings, the other extremities of which are connected to the machine terminals. The potential around the commutator varies as a curve of which the complete wave length or period is the circumference of the commutator. but a multiple connection from each ring may be employed, together with a step-down drive for the rings and commutator, whereby several complete potential cycles may be obtained around the commutator. Fig. 2 shows this method in which each of the rings Q is connected to three commutator segments 120‹ apart in a bipolar machine, the rings and commutator being geardriven at one-third of the speed of the rotor. Two separate stator windings may be employed, each with its slip-rings and commutator, these being connected to the rotor in series or parallel. Figs. 5 and 6 show means for mounting the sliprings in a common plane. The rings fare carried by discs A, B having cavities e through which the connecting-leads are brought to grooves between the discs and the shaft F. The brushes are carried by holders g, h mounted on each side of the discs. The invention may be applied to alternating-current commutator generators of the type described in Specification 210,482.

Title: Improvements in or relating to pulse generators
Inventor: REES FREDERICK HENRY
IPC: H04M19/02
Filed: 1964-04-22
Abstract: 1,002,716. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. April 22, 1964, No. 16653/64. Heading H4K. A number of pulse generators, each of which produces a complete repertoire of pulses for an exchange, but which are not synchronized with each other, are all kept in action but only one is connected to the exchange, the connected one at least being monitored so that should it fail it is disconnected and another generator is switched in. Since the exchange is stopped for the short period it takes to switch between generators it is contemplated that the exchange will store sufficient information to preserve its current functions although the loss of some connections is regarded as acceptable in some circumstances. As shown the generators PG1, PG2, PG3 have one of their outputs connectible by ferreed contacts A1, A2; B1, B2; or C1, C2, to a highway OCx for distribution. Pairs of contacts are employed in series to reduce the chance of failure if contacts fail and stay closed. Monitors PM1, PM2, PM3 watch over the output of each generator and signal faults to the central switching network CSN which governs which generator is connected. The pulses on the high way OCx are also monitored by the circuits PMM1, PMM2. Each monitor is connected to an alarm circuit AL, the outputs of the connected generator being connected over a decoupling diode resistor combination. With the occurrence of a fault an audible or visual alarm is given and the central network CSN disables all generators, disconnects the generator in current use, connects a substitute, resets all the monitors, and then removes the inhibition on the generators. If the fault signal persists a similar sequence substitutes the next generator. If the fault still persists the high way monitor PMM1 is disconnected and the generators are tried once more. If despite this the fault remains, PMM2 is disconnected and the generators are tried in turn once more. If the fault cannot be cleared by these means, the system reverts to the pulse generator in service when the fault was first detected and no further action is taken beyond the alarm signal.

Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B20/00
Filed: 1943-10-18
Abstract: 570,934. Hydraulic control systems. BENDIX AVIATION CORPORATION. Oct. 18, 1943, No. 17136. Convention date, Dec. 28, 1942. [Class 69 (ii)] A liquid-pressure remote control for use on aeroplanes &c. comprises a master piston 14 operating a slave piston 38 by liquid conduits 24, 26 leading to a valve chamber 22 containing locking valves 56, 64 controlling communication with the ends of the slave cylinder. Motion of the master piston causes compressed liquid to open, e.g. valve 56 to pressure liquid and to move a piston 48 in the chamber 22 to the right, thus opening valve 64 also and allowing escape of liquid from slave to master cylinders. If e.g. conduit 24 should break, pressure is released in the left end of chamber 22, allowing a spring to press a piston 74 to the left and so by a lost motion to pull valve 56 open and connect the left hand of the slave cylinder to atmosphere ; the piston 74 also opens a valve 80 and through a passage 82 connects the back of valve 84 to atmosphere, releasing liquid in conduit 26.and allowing valve 64 to be opened by piston 86, thus releasing the lock. A preload is normally maintained by an accumulator 100 through a check valve 110 pressed up by a spring to an upper part and allowing slight leakage and valves 116; the latter valves open on relief of pressure by breakage of the conduits and the consequent rush of liquid closes valve 110, preventing loss of preload liquid. The valves 116 and valves 120 allow thermal compensation. If either conduit 24, 26 becomes too full so that slave piston 30 reaches the end of its stroke before master piston 14, the stem of one of a pair of valves 36 in piston 30-abuts on the cylinder and allows transfer of liquid through the piston to the other conduit, the second valve being opened by liquid pressure.
