Title: Improvements relating to weighting motions of looms for weaving
IPC: D03D49/08
Filed: 1921-03-19
Abstract: 181,817. Gledhill, W. March 19, 1921. Letting-off warps. - In a loom weighting- motion having spring-controlled levers, the normal tension on the warp threads is relieved at intervals by one or more cam or tappet actuated levers. which take or partly take the weight of one or more springs off the warps and allow of it to come on again as required. Springs A, A<1> Fig. 1, adjusted by a hand-wheel a<1>, Figs. 1 and 3, bear on a bar C, which tensions chains or ropes D passed around ruffles e of a warp beam E. The ends of the leaf-spring A are connected to arms b rigidly fixed on a shaft b<1>, which when rocked by a tappet-actuated lever B, takes the pressure of the spring ends off the bar C. The bar may be free to rise and fall on guides. The lever B is timed to relieve the tension during the opening of the shed and to restore it when the shed is closed. Spring-controlled hooks d<1> turn the beam forward a little when the shed is opened. In turning the beam back or for removing it, the tension is wholly removed by operating a hand-lever F, Fig. 4, which turns a crank in the chain circuit to slacken the chain; or each spring may be provided with a lever for temporarily compressing it. Instead of a single bar C, two separate bars may be used, one for each ruffle, and such bars may be pivoted together or mounted on separate pivots at their inner ends.

Title: Improvements in electric time-switches
IPC: G04F1/06
Filed: 1932-03-23
Abstract: 378,824. Retarding action of switches. SNAY, C., 8, Weinheimerstrasse, Schmargendorf, Germany. March 23, 1932, No. 8675. Convention date, March 25, 1931. [Class 38 (v).] In time switches actuated by the change of centre of gravity of a sandglass or like device, the lever d for rotating the sandglass A is only accessible through an opening i in the casing and during the actual timing process, takes up a position behind the casing so as to be manually inaccessible. The lever d is slidably mounted in a hole in the spindle carrying the sandglass A. To close the switch tne lever d is moved by the finger in a clockwise direction from the position shown in Fig. 1 till it strikes a stop a, passing over a retaining spring f on the way. During this process one of two conducting studs c moving with the spindle strikes an insulating plate e on an arm b biased by a weight Q and eventually slips off the plate on to the arm to close the circuit. On removing the finger the lever d falls through the hole in the spindle into its inaccessible bottom dotted line position. The sand now runs into the bottom portion of the glass and at the end of the timing period the change of centre of gravity causes the spindle to rotate still further till the stud c reaches the end of the arm b and the arm slips down to break circuit. The lever d is now accessible and the switch is ready for further operation. The switch may be locked in the closed position by a rod o entering a hole s in the spindle or by other suitable devices.

Abstract: 466,981. Wireless receiving circuits. PHILCO RADIO & TELEVISION CORPORATION. March 27, 1936, No. 9136. Convention date, April 8, 1935. [Class 40 (v)] A wave trap is provided to suppress medium wave image frequencies when a set is receiving long-wave stations and switching means is provided for making the long and medium wave receiving coils ineffective when medium and long waves respectively are being received. If necessary a long-wave trap may also be used when the set is switched for medium wave reception. When the set is to receive long-wave stations, the switches S1, S2, are in positions B, B1 ; coil L2 is shorted to earth and coils L1, L4 are in series but only coil L4 is coupled to the secondary circuit. Coil L1 is broadly resonant to the medium wave frequency band and presents a very high impedance to medium wave signals whilst the suppression of the signals is further enhanced by the shorting of coil L2 to earth. The coil L1 is of low impedance compared with the coil L4 for the long wave signals, which it is desired to receive. When the switches S1, S2 are in positions A, A1 the coils L1, L4 are in shunt relation with the coil L2 and coil L5 is shorted. Image rejection in this frequency band occurs by virtue of the location of the intermediate frequency but if necessary a parallel tuned trap may be provided. The coil Cl serves as a pad for the tuning condenser VC when the switch S1 is in position B and as a coupling impedance only when the switch is in position A.
