Title: Improvements in or relating to automatic or semi-automatic telephone systems and apparatus for use therewith
IPC: H04Q3/00
Filed: 1923-12-12
Abstract: 230,547. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. Dec. 12, 1923. Automatic exchange systems; metering; selectors.-In a unimotional rotary switch, a pair of wipers insulated from one another are adapted to engage common bank terminals except in a particular position of the switch where they engage separate terminals. As applied to step-by-step switches of well-known kind, a pair of wipers which are normally interconnected and grip the bank contacts on the upper and lower faces, are separated by a washer of insulating material so that each may be used in a separate circuit. In any particular position the bank contact may be split and the upper and lower portions insulated from one another. The invention is described as applied to a line-switch in which the two wipers 16, 15 of one of the wiper pairs are separated and engage split contacts 20, 21 in the normal position, the lower wiper 15 being used in the test' circuit, but both being used in the restoring circuit. When the subscriber calls, the line relay 4 earths the private wire 3 and completes a series circuit for the switching relay 7 and the stepping magnets 8. The switching relay 7 is short-circuited over the circuit 13, 15, 21, 6, 5, but the stepping magnet R advances the wipers to the first contact set, where the split wipers 16, 15 engage a solid contact 22. If the associated line is busy, there will be earth on contact 22, the switching relay 7 will remain shunted, and the stepping magnet 8 will be again operated. This continues until the lower split wiper 15 engages an unearthed contact, whereupon the relay 7 energizes and the stepping magnet 8 remains inert. The switching relay 7 connects the line through, and at armature 11 prepares a circuit for the meter magnet 24, which is energized when earth subsequently comes back over the metering wiper 18. The'meter magnet locks to the private wire 3 to prevent accidental operation. When the calling party hangs up, the removal of earth from the release conductor 26 causes the relapse of the switching relay 7, and a restoring circuit is closed for the magnet 8, extending over armatures 5, 12 and both split wipers 16, 15. The wipers are then stepped round until the split contacts 20, 21 in the normal position are reached, and the restoring circuit is opened. On an incoming call, the switching relay 7 is energized, but since the wipers normally rest on dead contacts, no connection is made to an outgoing trunk.

Abstract: 537,026. Fluid-pressure servomotor controlsystems. C.A.V. Ltd., and EVANS, F. M. Dec. 4, 1939, No. 31386. [Class 135.] Relates to means for automatically controlling the throttle valve in the induction pipe of an internal-combustion engine for aircraft by an aneroid device, whereby the engine may be allowed to develop its maximum safe pressure at all altitudes up to the "full-throttle"altitude, whilst at the same time making it impossible for the pilot to obtain a value of induction pressure that would endanger the engine. An arm a on the throttle b is connected by a toggle c to one end of a bell-crank d which is also connected by a link e to the pilot's lever f. The other end of the bell-crank is connected to a datum-varying device. The junction of the toggle links c is connected by a link g to the rod h of a servomotor piston i working in a cylinder j having inlet and exhaust passages m, n, controlled by a valve o. The aneroid device comprises an elastic metal bellows p mounted within a chamber on a flexible diaphragm s which divides the chamber into compartments r, r<SP>1</SP> of which r is in connection at u with the induction pipe and r<SP>1</SP> at y with the exhaust or with atmosphere, the diaphragm s being thus subjected to the difference of these pressures. The diaphragm is loaded on each side by a suitable rated spring t, and the bellows p is supported by stems v working in guides w. A lever z has pin-and-slot connection with valve o and stem v is also pivoted to sliding part 2 urged upwardly by a spring 3 and adapted to be moved to vary the datum by a cam 4, an arm 5 on which is connected by a link 6 to the bell-crank lever d.

Title: Improvements in or relating to rail track vehicles

Filed: 1954-11-04
Abstract: 798,087. Mounting bodies on rail vehicles. ODDIE, J. M., and INGHAM & SONS, Ltd., J. Feb. 6, 1956 [Nov. 4, 1954], No. 31866/54. Class 103(6) [Also in Group XXXIV] In a rail .track vehicle, especially a vehicle for mine working, of the kind in which the weight of the vehicle is used for actuating the brake mechanism, ground clearance of the vehicle being maintained by pressure in a pneumatic or hydraulic system, the system incorporates a pressure release or trip valve the operation of which is controlled by means of a speed-sensitive governor. As shown, a mine car comprises a frame 1 having a hydraulic suspension system 2 and brake shoes 3, as described and claimed in Specifications 783,231 [Group XXIII] and 785,157 [Group IV(a)] and the hydraulic system includes a reservoir 5, pump 6 with operating lever 14, and a release or trip valve 7, the latter being operated by a spring-loaded toggle mechanism 12. The mechanism is operated by a centrifugal governor 11 when a predetermined maximum speed of the axle 10 is reached, the mechanism then passing over its dead centre position so that the spring 13 strikes the valve 7 and releases fluid pressure in the suspension system. This causes the frame 1 to fall towards the rails and bring the brake shoes into operation. The toggle mechanism may be set manually by rotating a shaft 15 which is connected to the toggle mechanism by a push rod 20, and is also connected by a lever arm 17A, pull rod 18A and adjustable chain and hook to the next car. The push rod 20 is also connected to a shaft 22 at the other end of the car which is connected to the adjacent car, so that if one of the cars breaks away from the train the chain will tighten and cause rod 20 to operate the toggle mechanism and hence the release valve 7. The invention may also be applied to a "gondola" type of mine car, Figs. 4 and 5 (not shown).
