Title: A plying and twisting frame adapted to deliver cross-wound yarn packages
IPC: D01H1/08
Filed: 1960-09-01
Abstract: 918,963. Plying and twisting frames. HART & ZN. INSTRUMENTENEN APPARATENFABRIEK N.V., W. C. 'T. Sept. 1, 1960 [Sept. 3, 1959], No. 30239/60. Class 120 (2). A plying and twisting frame for delivering cross-wound yarn packages includes at least one unit comprising two rotatable twist pots 3, 4, Fig. la. The strands 53 to 56 to be twisted are fed via a feed roller 32 into one of the pots by a yarn guide 19 whilst the twisted yarn in the previously filled pot 4 is emptied through a yarn guide 20 on to a cone 57. The yarn guides 19, 20 perform traversing motions in the pots 3, 4, and each comprises a tube having a freely rotatable mouthpiece 23, Fig. 2, provided with radial grooves 27. The grooves 27 ensure that the yarn, as it enters and leaves the pots 3, 4 is twisted in the guide tubes 19, 20. When the twist pot 3 has been filled the incoming strands are severed above the guide tube 19 and are then led into the guide tube 20 of the now empty pot 4, and the twisted strands protruding from the guide tube 19 are then led via the feed roller 32 to the cone 57. The feed roller 32 is so positioned that the inclination of the yarn leaving the roller 32 with respect to the vertical is the same independent of which twist pot the yarn is fed to. Each twist pot is enclosed in a stationary jacket 3a, 4a to reduce aerodynamic losses. Creel arrangement.-The strands 53 to 56 are drawn from alternate supply packages 37 on an arcuate frame 36, the intervening packages being replacement packages. Driving apparatus for twist pots.-The plying units extend along the machine on each side thereof so as to form four parallel rows of twist pots, each pot being mounted on a whorl 11, 12. Between each group of four pots is a pulley 15 having a belt passing over the four whorls of said pots. The pulley 15 is coupled to a spindle 14 carrying a further pulley 16 beneath the machine. A belt from a drive motor zig-zags between the pulleys 16 along one side of the machine and then returns in zig-zag fashion between the pulleys 16 on the other side of the machine. The belts on successive pulleys 15 are arranged in opposite directions so that all the twist pots of the whole machine shall rotate in the same direction. Winding the cone.-The twice twisted yarn is passed to a helically grooved guide roller 39 against which is pressed the cone 57. The cone is held against the roller 9 by a push bar 52 having a sheave 51 at its lower end. A weight 48 has a cable 49 that passes over an eccentric sheave 50 on a fixed arm 38, thence under the sheave 51, and finally up to a fixed point on the arm 38 again. The eccentricity of the sheave 50 is chosen so that the leverage of the weight varies with the increasing dimension of the cone during its winding. A shock absorber 41 is included.

Title: Improvements in or relating to electric signalling systems
IPC: H02J13/00
Filed: 1928-10-24
Abstract: 301,418. Maschinenfabrik Oerlikon. Nov. 29, 1927, [Convention date]. Selective signalling apparatus.-In a system for supervising the control of electric power switches at a remote substation from a supervising station, the attendant at the substation is notified of the switches to be operated by electromagneticallyoperated indicators which are connected to similar indicators at the supervising station in such a manner that the positions of the corresponding power switches and also failure of the signals and circuit may be notified at both stations. The Figure shows a system for supervising a singlepower switch. Normally the indicators SMK, SMS at the supervising and substation respectively are connected in series with a resistance or impedance W over the corresponding contacts of the switches K, U, the latter of which is coupled to the power switch being supervised. The normal current operates the indicators into a position signifying that the power switch and the switch K occupy corresponding positions. In order to instruct the attendant at the substation to operate the power switch, the switch K is reversed to switch out the resistance W and thereby increase the current so as to move both indicators into a further position. When the switching operation is performed, the switch. U is automatically reversed to re-establish normal conditions. Automatic operation of a power switch effects a signal in a similar manner, acknowledg ment of the signal to establish normal conditions being effected by reversing the switch K. In the event that the signalling circuit becomes broken by reason of a defect in the line wires or switch contacts, the indicators are returned to their zero positions to indicate such condition.

Abstract: 680,020. Control of motors. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and MANN, C.A. Nov. 30, 1950 [Dec. 1, 1949], No. 30889/49. Class 38 (iii). [Also in Group XXIX]. A control valve for fluid and applicable to the breaking of the vacuum in a chamber when the electric supply to the motor-driven vacuum pump fails comprises a screw-threaded housing in which a screw-threaded valve 1 is rotated by an electric motor 9 through an extensible drive to open the valve on the closure of a motor switch, the valve acting as a movable electrical contact to open the motor circuit at or near the end of the opening movement. As shown, when the mains supply to a vacuum pump fails a coil 20 allows a switch 19 to close so that an auxiliary electric source 11 operates the motor through the two-pole switch 14, 15, 17, wire 21, the valve and housing, the splined motor shaft 8 engaging a recess 10 in the valve, the slip-ring 22 and the wires 23, 25. The valve opens to relieve the vacuum in the chamber 3 and breaks the motor circuit when it leaves the housing. To close the valve the switch 14, 15, 17 is moved by hand, e.g. against a return spring, to complete the motor circuit through wires 26, 28 and a stationary metal block 30 insulated from the housing and receiving the valve 1 in its open position. In a modification, the motor is moved away from the valve which is then closed by hand and the motor returned to engage the valve through its shaft or a spring. The relay 19 may be dispensed with, and the valve opened and closed automatically by the coil 20 operating the switch 14, 15, 17. In another embodiment, the valve carries contacts which bridge brushes in its open position.
