Title: Improvements in looms for weaving in which the shuttle boxes do not move with the sley
IPC: D03D49/60
Filed: 1932-07-04
Abstract: 404,312. Looms having shuttle-boxes which do not move with the lay. BRITISH CELANESE, Ltd., 22, Hanover Square, London, HALE, F. C., and BENNETT, J. W., c/o British Celanese, Ltd., Spondon, near Derby. July 4, 1932, No. 18826. [Classes 142 (i), 142 (ii), and 142 (iii).] In a loom having shuttle-boxes 12 carried by brackets 11 on the loom frame, the lay, which is furnished with a shuttle race and reed, is driven through a spring link 19 from connected levers 20, 23. These are driven by cams so as to give a dwell to the lay when this is in its rear position and the picking occurs. The shuttle boxes have spring-controlled pivoted parts 32, which yield if the shuttle fails to enter properly. The entering shuttle forces back a swell 35 pivoted at 34 thereby turning a lever 36 and rotating a swell spindle 37 common to both shuttle boxes against the action of a spring 38, so as to swing downwardly a lever 39 provided with three rollers 40 engaging a curved rod 41 pivoted to the lay sword. The rod thereby raises a catch 43 clear of spragging mechanism but when the shuttle fails to box the spragging mechanism is engaged and by means of a link 45 applies a brake 46 to a brake drum 30 furnished with a balancing weight 31. A spring 47 normally holds the brake in the "off " position, an adjustable stop 49 being provided. During the stopping of the loom, the spring- link yields and the compressed springs thereof hold the brake against the brake drum. A further checking swell 51 is provided acted upon by a spring controlled lever 57 on a sleeve carrying a lever 55, which is at intervals acted upon by a cam-controlled lever 52 to ease the swell for picking. When the weft fails, a weft fork passes through a grid on the shuttle race and is engaged by a hook 64 on a cam-controlled lever 65 so that a lever 70 carrying the weft fork is operated and through a nose 72 and lever 73 knocks off the starting handle 74 to stop the loom. The weft-stop motion also acts to stop the loom when the lay fails to reach beat up position. The loom may be provided with drop boxes or rotating boxes, and cop or shuttle changing mechanism may be incorporated with the shuttle boxes. Weft may be inserted by a dummy shuttle as described in Specification 346,850 and may be tensioned by means carried by the lay as described in Specification 360,818. The loom may be used in weaving warp pile fabrics wherein two fabrics are woven together and severed from each other.

Title: Disconnectible selective call receiver
IPC: H04W88/02
Filed: 1955-07-01
Abstract: 806,222. Electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. (Lorenz A.G., C.). July 1, 1955, No. 19075/55. Class 40 (1). [Also in Group XL (c)] In a selective calling system for calling one of a plurality of radio receivers the call indicating parts S of the receivers are connected to and operated by the main receiver H only after operation of auxiliary receiver parts K operated by a signal transmitted to all the main receivers H. By this means the selectively energized parts S need hot have filters protecting them against speech frequencies and may operate with a reduction in their time of response, so enabling calling by dialling frequencies to be speeded up. The common signal may be a line clear signal which energizes a relay N of the permanently ready to receive portions K of all the receivers and therefore a relay Z to prepare all the call selecting parts S for possible reception of a call. Provided then within a predetermined time after cessation of a line clear signal, determined by the charge on a condenser C shunting the coil of the relay Z, selective circuits 10, 11 of one receiver are energized to operate relays X, Y, a further relay O pulls up to close contact O1 and signal an alarm and contact 02 so that relay Z and the call selector S remain responsive throughout the duration of the selective calling. Only then after the selective calling ceases is the selector S disconnected from the main receiver H at contact Z. Alternatively a call signal, other than the cessation of " line clear " common to all the receivers, may initiate a switching process disconnecting all the selectors S after a certain time except the one called. In a modification (Fig. 1, not shown), a call is begun by a frequency operating a relay which, through a holding circuit, connects up the main receiver H to the selectively called part S. Also a call is made'to end with a further frequency which interrupts the holding circuit and first operated relay and therefore disconnects the selectively called part S.
