Title: Improvements in or relating to cleaning devices for yarn or the like
IPC: B65H63/06
Filed: 1938-04-29
Abstract: 514,385. Yarn clearers. UNIVERSAL WINDING CO. April 29, 1938, No. 12901. Convention date, May 10, 1937. [Class 120 (ii)] Yarn or the like is passed between opposed relatively, adjustable cleaning members one of which is moved by a spring to vary the gap when the securing means are loosened, the cleaning members being adapted to co-operate with a gauge to limit their relative movement. The cleaning device is shown in Fig. 2 and the separated parts of it in Fig. 6. The framework 2 has a web 5 substantially of the form of a right angled triangle partly bounded by a marginal flange 3. Near the base is a slot 6 the lower face of which is widened to form a flat ledge 7 over which the yarn is drawn. The movable cleaning element is a flat blade 10 with a true edge 11 and an inclined edge 12 which abuts against the inner face of the part 4 of the flange 3; the blade also has a rectangular opening 16. A rectangular block 20 rests in the lower corner of the flange 3 and forms a seat for the cover plate 25, the lower part of which is cut away so that the part 27 is above the ledge 7. A spring 30 is arranged between the flange 3 and the end 14 of the blade. When the parts are assembled the cylindrical head 36 is pushed into the opening 38 in the web 5 until the flange 37 rests against the web. The centrally placed screw 35 on this head passes through the blade opening 16 and the nut 40 is screwed on to hold the blade; the cover is then put on so that the opening 29 embraces the nut. The cover is then secured by the screw 23. To adjust the cleaning gap the head 36 is turned by the wrench 45 to loosen the nut 40 and to cause the crank pin 41 to move the blade 10 back against the spring 30. A gauge G of the required size is placed on the ledge 7 and the head 36 is turned in the reverse direction so that the blade 10 is moved by the spring to rest on top of the gauge. Continued movement of the head tightens the nut 40 and the gauge can then be removed. The yarn is drawn through the gap between the ledge 7 and the edge 11 of the blade, and is given a reciprocating movement so that slubs, bunches, motes and the like are removed.

Title: Improvements in the manufacture of water gas and apparatus therefor
IPC: C10J3/00
Filed: 1938-05-02
Abstract: 508,617. Water gas generation. HUMPHREYS & GLASGOW, Ltd., and SMITH, J. H. May 2, 1938, No. 13033. [Class 55 (i)] In the intermittent process of generating water gas, the generator and the set beyond the generator are each purged separately and successively after the blast period or after a back run period, the purging of the set beyond the generator in the latter case being effected by the back run itself. In a usual water gas set having a waste heat boiler c, a wash box d, air blast valve e, secondary air blast valve f, gas valves k, l, steam control valve h and three-way valve i, the latter connects on the one hand to the back run steam inlet n and on the other hand to three-way valves p, q, which can direct the steam to the base of the generator or to the secondary air blast pipe o, the valve p being controlled by the stack valve g and the valve q by the secondary blast valve f. After the usual blast period, the generator a is upwardly purged with steam, the valve q being set accordingly ; the secondary air blast valve f is now open and the purged gases from the generator are burnt in the regenerator b until the evolving water gas is sufficiently low in nitrogen content. The blast valve f is then closed which automatically moves the valve q to direct the steam into the pipe o for purging the set beyond the generator, the stack valve g being open. The latter is finally closed which automatically reverses the valve p so that the steam passes directly to the base of the generator for an up-run. The invention may then be applied after a backrun which may then follow, with the valves set accordingly. After this period, since the set beyond the generator is full of steam, only the generator is purged. Steam is supplied to the generator base, gas valve l being open and k closed. The succeeding blast with both blast valves e, f open drives out and burns any remaining water gas in the generator. The purging in either case effects an economy in the water gas produced. Specification 508,618 is referred to.'

Patent GB-646100-A (GB)
Title: Improvements in or relating to electric circuit breakers having electromagnetic tripdevices
IPC: H01H71/44
Filed: 1948-05-13
Abstract: 646,100. Electromagnets. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 13, 1948, No. 13166. Convention date, May 17, 1947. [Class 35] [Also in Group XXXVII] The electromagnetic tripping device of an automatic circuit-breaker, comprises a sealed casing, movable with a magnetic armature 153 and containing a body of fluid, and a magnetic core 159 which remains substantially stationary during the tripping movement of the casing, the core having an axial opening receiving a retarding member movable with the casing, so as to control the rate of fluid flow through the opening. In the application of the invention to the circuit-breaker of Specification 530,197, the armature 153 is sealed to the non-magnetic casing 151, the core 159 being urged into the position shown by a spring 167. A non- magnetic valve housing 165 in the casing contains a valve 179 and valve-rod 183 normally spring-urged to the closed position shown. On a light overload, e.g. up to 1000 per cent of normal load current, the armature 153, and thus the casing 151, are attracted upwards, the tripping movement being delayed by the flow of fluid through the small annular space between the core 159 and the valve housing 165. On a moderate overload, e.g. between 1000 and 2500 per cent of normal load current, the fluid pressure created in the casing by movement of the armature is sufficient to lift the valve 179, so that fluid also moves up within the housing 165 and out through orifices 189, thereby reducing the time delay. On an overload above 2500 per cent, e.g. a short-circuit, an armature 203 is instantaneously attracted upwards to strike a pad 237 and move the entire core structure upwards. The tripping movements are normally opposed by a spring 221 acting on a member 217 which engages between two projections 215 on the core structure, although by sliding the fixed end of the spring sufficiently far upwards in the slot 233 in the support 199, the spring will move over-centre and aid the tripping movement. In addition, the initial position of the armature 203 is adjustable by a screw 207. The valve 179 and housing 165 may be replaced by a solid rod 1651, Fig. 1, of any suitable size, so as to produce the same time delay on all overloads up to 2500 per cent. The armature 203 may be omitted if desired. The fluid used is preferably a polymeric silicone, e.g. dimethyl silicone, diethyl silicone, phenyl, methyl silicone and phenyl alkyl silicone. The trip device is stated to be suitable in 'the selective and cascade tripping of a number of series circuit-breakers in a motor circuit. Specification 619,477 also is referred to.
