Title: Improvements in or relating to switch circuits for use in telephone or like systems
IPC: H04M3/60
Filed: 1935-06-21
Abstract: 458,725. Semi - automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HARTLEY, G. C., 63, Aldwych, London. June 21, 1935, No. 10551/36. Divided out of 458,838. [Class 40 (iv)] A bidirectional finder switch F, Fig. 4, which extends calling lines to a toll operator's position, has one level wired to group selectors over which the operator may recall a calling party, and hunting over this level takes place in response to a marking applied from the operator's position. The finder is controlled by common apparatus, and is linked to a switch S which gives access to the toll and local switch trains. On an incoming call, a group relay such as GA (not shown), connects up start relay S and marks the level of the calling line. Lamp WCL lights, and the operator throws the speak key SPK of a link, . operating relays CA, CB, MN, and then the accept call key ACK, Fig. 5. Relay AC, Fig. 1, energizes and the switch AS rotates into engagement with the assigned link, when T pulls up over the operated keys. Relay TT energizes, connecting T to wiper 1 of AS and closing a circuit over wiper 2 for ST which interacts with the vertical magnet VM of the finder F until T energizes over vertical wiper ffm and the marked level. Relay ST remains up, and C energizes, disconnecting ST, S and T. A fresh circuit is made for ST, which now interacts with the rotary magnet RM until T energizes over wiper fem and connects up switching relay KR, whereupon the common apparatus is released. When the finder F is used to select an idle group selector, the operator throws the sending key RKSK, Fig. 5, in addition to keys SPK, ACK, in order to associate a sender over the switch SF, HR then being operative. Relay AC, Fig. 1, operates in series with D, which connects up start relay S. The first level of the finder is marked over key ACK and a contact of HR, and the finder operates as described above to hunt over that level. An idle group selector is marked by battery over wiper fem, and the guard relay is connected up directly by switching relay KR.

Abstract: 953,481. Moulding refractory bricks. GENERAL REFRACTORIES Ltd. Feb. 14, 1963 [March 20, 1962], No. 10555/62. Heading B5A. [Also in Division F4] A metal clad refractory brick comprises two L-shaped plates disposed at diagonally opposite edges of the brick and spot welded where they overlap two angle strips contained in recesses in the two parallel, remaining edges. A refractory block has recesses 6 containing metal strips 7 to which are welded L-shaped plates 1, longitudinal movement of the strips being prevented by the shoulders 8. In further embodiments the strip may be notched and the notched portions located in individual recesses or the notches may be bent to enter the block at the longitudinal reentrant corner of the recess. A mould box 13, Fig. 5, with plungers 14 and 15 is fitted with recess forming strips 16 and 17. When the strips are co-moulded with the brick one strip is placed at a lower corner of the mould, the correct amount of refractory material is applied and the other strip is finally pressed in position. The recess may be formed with a combustible material which is left in position after moulding and burned out during firing. The invention may be applied to bricks comprising two or more refractory blocks, Fig. 8, recesses being provided at diagonally opposite corners of the brick and spacers, suitably flanged to prevent movement (Fig. 9, not shown), being placed between the blocks. The blocks may be supported by extending the casing and providing suspension holes in the extensions or a hole may be formed through the complete brick.

Filed: 1936-04-14
Abstract: 478,422. Two-stroke engines. FITZGERALD, W. M. B., and RATCLIFFE, T. April 14, 1936, No. 10650. [Classes 7 (ii) and 7 (vi)] In an engine in which the combustion chamber 13 is isolated from the expansion chamber 16 by a valve 17 and from a conveyer duct 11 by a valve 12, an air charge is compressed into the duct 11 through a valve which closes at the end of compression and fuel is supplied to the air charge when in, or when entering, the chamber 13 at the end of compression or immediately after ; ignition, e.g. by means of a sparking-plug 14, is effected before the end of the exhaust stroke, exhausting taking place past a valve 18 ; the valve 17 opens at top dead centre, and the spring-loaded valve 12 opens before valve 17 closes to deliver an air charge to scavenge the chamber 13. The duct 11 may be cooled, e.g. by placing it and its supply pipes 10 in the cylinder water jacket, or in a separate water jacket, or providing it with aircooled fins. The air may be compressed by the underside of the piston, or by a port thereof if a differential piston is used, or it may be supplied by a separate compressor. In a multicylinder engine, the charge in one cylinder may be compressed by the piston of another. A single conveyer duct arranged between two cylinders may serve for the combustion chambers of both. The piston closely approaches the cylinder head so that the expansion chamber is thoroughly scavenged. The engine may run on gas, light oils or heavy oils, and the isolated charge may be held in the chamber 13 for half a working stroke so that thorough mixing takes place. Specification 478,471 is referred to. Valve gear.-A shaft 56, operating the exhaust valve 18 through a rocker 55, is oscillated from a push-rod located substantially behind the valve through a rocker, pivoted coaxially with a shaft 43 and a pair of opposedtoothed quadrants.

Abstract: 858,350. Pleating machines. VISKASE Ltd. April 2, 1959 [April 3, 1958], No. 10918/58. Class 141 In a pleating machine for producing converging pleats, wherein an upper set of pleating arms 9 is pivoted at one end 23 so that the other ends of the arms may interengage with the arms of a lower set, the arms of both sets are pivoted individually at 8 for horizontal angular movement so that the interengaging ends of the arms can be made to converge. The two sets of pleating arms are mounted on upper and lower sections 5, 4 of a slidable carriage. Associated with each. set of arms is a guide plate 15, 12 having series of converging slots 14 engaged by pins 13 fixed to the arms 9. The guide plates are longitudinally stationary but the upper guide plate is arranged to pivot with the upper carriage section 5 so that on forward and pivoting movement of the carriage the pin-and-slot connections cause the arms to converge as they interengage. At the end of each arm 9 is a vertically pivotable finger 10 with a projection 21 anchored to the corresponding guide plate by a coiled spring cable 22. As the carriage nears the end of its forward travel the tension in the springs causes the fingers 10 to pivot away from the pleated material. The operative edges of the arms 9 of each set are covered with a fabric layer. The machine may be used to pleat one end of a tubular casing of regenerated cellulose. In a modification the carriage is longitudinally stationary and the guide plates are movable to effect interengagement and pivoting of the pleating arms.

Abstract: 703,986. Knitting-machines. MELLOR, BROMLEY & CO., Ltd. March 19. 1951 [May 5, 1950], No. 11195/50. Class 74 (2) To avoid unnecessary action of a stop motion for a knitting-machine, a pivoted lever 9 over which the yarn passes to the needles. has an arm 18, provided with a slot 21, associated with it so that the yarn engages the end of the slot when urged towards the arm by the lever 9 in the event of slackness of the yarn,. thereby causing the yarn to prevent undue movement of the lever 9 and operation of the stop motion. The end opposite the yarn engaging end of the lever 9 is biased by a weight 11 to pivot the lever 9 and make contact with a member 13 forming part of a switch in the electrical circuit of the stop motion.. The yarn engaging end of the lever 9 may beforked and between the prongs 10 of which the end 20 of the arm 18 depends. Attached to the arm 18 may be a plate 22 which is adapted to. form a loop in the yarn as the lever 9 moves the yarn towards the arm 18 and thereby assist in taking up some of the slackness. The lever 9 is also influenced in the event of the yarn becoming unduly tensioned by a spring 25 which restricts the movement of the lever 9 towards a second member 31 of the switch in the electrical circuit of the stop motion. Alternatively, the arm may comprise two tongues 42, 44, Fig. 5, which cause the yarn when raised by the forked end of the lever 9 to engage the slots 45 and kink into loops to take up the slackness in the yarn and also to increase the friction between the yarn and the device thereby restricting movement of the lever 9.
