Title: Improvements relating to stop motions for thread-consuming textile machines
IPC: D03D51/28
Filed: 1944-06-29
Abstract: 587,406. Stop-motions for knitting-machines. JENNINGS, H. W. K. (Van Raalte Co., Inc.). June 29, 1944, No. 12417. [Class 74 (ii)] [Also in Group IX] In a stop-motion for thread-consuming textile machines in which a broken or slack thread portion is rendered electrically conductive, a current of fluid is directed towards the threads and urges the thread portion towards a pair of spaced electrodes, which can be bridged thereby to close an electrical circuit by which the machine stopping mechanism is operated without the interposition of drop wires. A tube 40 mounted above the warp threads of a knitting- machine is connected with a source of compressed air and, on the side facing the warp, is provided with a series of jet-openings 45. The tube is constantly reciprocated, so that each jet acts in turn against a number of warp threads. A roller 24 dips into a pan of electrically conductive liquid 26, being evenly coated therewith by a wick 27. The roller 24 preferably forms one pole of the input circuit to the amplifiers of a machine stopping device similar to that of Specification 565,182, and the other pole is formed by two conductors 37, 38 and a roller 29 rotated with the roller 24. Any broken or slack thread is blown into contact with the roller 24 and one or other of the conductors 37, 38, or the roller 29. The broken end wets out and becomes conductive, the input circuit to the amplifier is thereby completed, and the machine is stopped. The reciprocation of the tube 40 is effected by a uniform motion cam acting in opposition to a helical spring.

Abstract: 733,359. Making articles by electrodeposition. ELLIOTT BROS. (LONDON), Ltd. May 22, 1953 [May 22, 1952], No. 13047/52. Class 41. [Also in Group XL (b)] A wave-guide component is made by forming in the surface of a block of metal open channels or recesses each of which requires to be closed by one or more additional walls to constitute a passage for use as a wave-guide, filling each channel with a core element which has previously been, or is subsequently shaped accurately on its exposed surface, depositing a layer of copper or other suitable metal electrolytically on the exposed surfaces of the block and core, and subsequently removing the core from the passages thus produced. In one example a block 2 of brass or copper (Fig. 2) is formed with grooves 3; 4 and 5, which are filled with wax or low-melting metal or alloy, the exposed surfaces of which are then accurately finished to lie in the same planes as the contiguous faces of the block 2. These faces together with the surfaces of the wax or alloy are then electroplated with copper to a suitable thickness, the wax, if employed, having been given a conductive coating. When the wax or alloy is removed by melting or dissolving, passages 6 (Fig. 3) are obtained. Parts of the block may be machined away as in Fig. 3. Examples of other designs are described. Where suitable, a channel may be filled with an accurately finished mandrel, of, for example, stainless steel, which is extracted after the plating has been completed. When wax or similar material is used the exposed surface may be made electrically conducting by coating with graphite or by depositing silver from a mixture of a silver salt and a reducing agent.
