Abstract: 942,737. Jet looms. W. SCHEFFEL. May 13,1960 [Dec. 5, 1959], No. 33666/62. Divided out of 16908/60. Heading D1E. In a loom in which weft S is propelled through the shed by a jet of air from a nozzle 9 and received in a suction nozzle 10, additional nozzles in pipes 2,3 direct air towards the flight path of the weft. The pipes 2, 3 are mounted on the slay so as to be carried clear of the warp at beat-up but to penetrate the upper and lower warp sheets when the slay is in its rear position where picking occurs. In a loom in which both nozzles 9, 10 may be used for pressure or suction to enable picking to be effected in either direction, alternate nozzles in the pipes 2, 3 face in opposite directions; air pressure is fed to one end or the other of the pipes, depending on the direction of the pick, so as to emerge from the nozzles pointing in that direction.

Abstract: 827,753. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 1, 1957 [Nov. 6, 1956], No. 33806/56. Class 37. A method of making a whisker electrode for a point-contact semi-conductor device comprises the step of flattening the electrode at a part spaced from the contact end. The electrode may be formed by a wire of circular cross-section which is flattened at a part which does not extend to the contact end and may not extend to the other end, the flattened part then being crimped into an S or C shape (Figs. 2, 4) or left straight. In other embodiments, the flattened part is bifurcated either at the end of the whisker (Fig. 12) or between the ends (Fig. 10), the two branches 7, 8 being crimped symmetrically ; they may be twisted into parallel planes, each 90 degrees away from their original plane before crimping; these forms are mentioned with reference to coaxial point contact transistors. The whisker may be attached to a mounting stub 4 by a circular end portion, as in Figs. 2, 10, either before or after flattening and crimping; alternatively, a flattened end portion of the whisker may be welded to the end of the stub, as in Fig. 4, or to a recess in a side of the stub, as in Fig. 12 or may be pinched into the stub. The branches 7, 8 of a bifurcated whisker need not contact the stub as in Fig. 10. Fig. 15 shows a whisker 14 of circular cross-section headed with a flexible disc 15 which is pressed into a recess 16 in the mounting stub 17, a cavity being left behind the disc. This whisker may be formed by forcing the wire 14 through a hole of smaller diameter and then pressing the surplus material to form the disc 15. The Provisional Specification also describes a whisker formed from unflattened wire bent into a figureof-eight shape across its longitudinal axis.

Title: Improvements in and relating to means for damping the recoil in railway vehicles or the like
IPC: B61F5/24
Filed: 1935-12-10
Abstract: 446,082. Railway-vehicle under-carriages. DANIEL, H. A. HOOD-, Crossways, Plumpton Green, Sussex. Dec. 10, 1935, No. 34201. [Class 103 (vi)] In order to lessen the jolting effects, particularly in recoil, due to the plunging or forward movement of a railway vehicle body relatively to the bogies or undercarriage when the brakes are applied, a piston and cylinder damping device operatively connected to the pressure or vacuum braking system is disposed between the vehicle body and the bogies or undercarriage. In the arrangement shown a casting secured to the body 1 forms two cylinders 2, 3 in which slide pistons 20, 21, one or other of the cylinders being connected with the braking system according to the direction of movement of the vehicle. The cylinders 2, 3 are provided respectively with orifices 31, 33 in their end walls, and in their side walls with grooves 36, 37 at one end of which are located spring-loaded valves 38. Each piston-rod 22 is connected by means of a pivoted lever 23 and divided rod 4 with one of the bogies 6, 7, curved guides 10, 11 on the latter permitting the necessary swivelling movements. In operation, if the vehicle is travelling in the direction of the arrow, Fig. 3, and the brakes are applied, the body tends to carry the cylinder casting to the right relatively to the pistons ; air is displaced from the lefthand portions of the cylinders through the orifice 31 and through the groove 37 by-passing the piston 21, a certain cushioning effect being exerted. At the same time the piston 20 uncovers a port 42 and connects the right-hand end of the cylinder 2 with the pressure braking system. During recoil, therefore, rapid movement of the piston 20 to the right is resisted, until the piston regains its normal position and opens the release valve 38. A valve under the control of the guard or driver permits a port 45 in the cylinder 3 to connect with the braking system when the direction of travel is reversed.

Filed: 1920-12-03
Abstract: 154,909. Wisconsin Electric Co., (Assignees of Beach, C. H.). Oct. 25, 1915, [Convention date]. Sewing - machines; driving. - Relates to starters or controllers for small motors such as sewing - machine motors and consists in a construction of rheostat for this purpose. The rheostat is composed of a hollow cylindrical body 1, in which are mounted the resistance coils and their sectional contacts, and a plunger 4 formed with a head which works in the body and carries a movable short-circuiting contact. In one construction the plunger is adapted to rest on the floor and the body is attached to a pedal 9. Normally a helical spring keeps the pedal raised and the short-circuiting contact out of action. Pressure on the pedal moves the body down and progressively turns on current until full strength is attained in the lowest position. In another construction the plunger is hung up to a fixed support and the body is attached by a chain or cord to a sewing-machine treadle.
