Title: Improvements in and relating to protective arrangements for alternating current circuits
IPC: H02H3/00
Filed: 1930-12-12
Abstract: 367,959. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Kennedy, L. F. ; Apt. 401A, Lecomey Plaza, 58th Street, Philadelphia, U.S.A.) Dec. 12, 1930, No. 37548. Convention date, Dec. 26, 1929. [Class 38 (v).] A relay for controlling a circuit-breaker in the connection of a supply such as the lowtension side of a distributing transformer to a feeder distribution circuit has potential and current windings the latter of which is arranged, while the circuit is completed, to be fed from a current transformer having a core of high magnetic reluctance as, for example, a core formed with a considerable air gap. As shown in the Figure, the distributing transformer 8 has the line end of its earthed secondary winding connected to a distribution circuit 5 under the control of a circuit-breaker 10 the tripping and closing coils 16, 17 of which are controlled at contacts 14, 15 of a wattmeter relay 11. The voltage coil 13 of the relay 11 is connected in series with a resistance 4 across the distribution circuit 5 the current coil being, when the circuit-breaker is open, connected between the two circuits. Thus the current coil, which under these conditions acts as a phasing winding controlling the closing of the circuit-breaker 10 when the feeder voltage exceeds that of the network by a predetermined amount, requires a relatively large number of turns as compared with the corresponding coil of the usual power directional relay. When therefore the current coil is utilized to control the tripping of the circuit-breaker 10 in accordance with direction of power, in order to prevent an excessive burden on the secondary winding of the current transformer supplying the current coil under these conditions owing to the high impedance current coil necessarily employed, the transformer is formed with a core of relatively high reluctance which condition may be fulfilled in the manner shown by providing the core 25 of the current transformer 24 with a substantial air gap. The characteristics of the relay thus ensure correct tripping in all necessary conditions as during the feeding back of the transformer magnetizing current when the primary circuit-breaker 9 is opened and prevents incorrect tripping, as by capacity currents in the transformer primary leads 7. The theoretical considerations underlying the tripping action are fully set forth in the Specification. A ballistic resistor 23 is included in the current coil circuit to protect the coil against excessive voltages in certain conditions. Specification 262,767, [Class 38 (v), Electric switches &c.], is referred to.

A winding 1 for a transformer or choke coil is compressed in the axial direction by means of hydraulically or pneumatically expanded bags 4 placed between one or both end faces of the winding and an envelope 6, 7 wrapped around the winding. In Fig. 1, pressure rings 2, 3 are placed adjacent the end faces of the windings and an annular bag is placed against ring 3. A paper cap 5 is placed over the bag and bundles or bands of glass fibre wires 6 are wound around the assembly. Gas or liquid under pressure is then supplied to the bag to exert the required compressive force on the winding. The assembly may then be coated in a hardening synthetic material 7 to render the envelope gas-andliquid-tight and the space 15 inside the envelope filled with transformer oil. If two concentric windings (as 16, 17, Fig. 3, not shown) are to be placed on one core leg, they may be separated by an insulating tube (19) and wrapped in a common envelope, but provided with separate annular bags (22, 23). The pressure ring may be formed with a projecting portion so that the adjacent surface of the bag is indented (Fig. 4, not shown). In this embodiment the bag(s) may be made of rubber or synthetic material reinforced by fibrous substances. In a further modification (Figs. 5, 6, not shown) a plurality of angularly-spaced cupshaped bags are disposed between two complementary-shaped wooden pressure rings. The bags may be constituted by bellows of metal, which may also act as potential-controlling rings.

Abstract: 838,159. Sound-receiving and transmitting devices. SIEMENS EDISON SWAN Ltd. Nov. 19, 1958 [Dec. 6, 1957], No. 38062/57. Class 40 (4). In a transducer of the balanced ring armature type the outer periphery of the armature 7 is disposed between two annular washer-like members 4, 5 secured in position between the outer annular portions 1 of the transducer magnetic structure, and the radial width of each of the members 4, 5 is significantly greater than that of the outer annular portions 1. The embodiment shown is intended to function as a transmitter and to this end its resonant frequency is lowered, to render it less sensitive to noise frequencies above the signal frequencies, by reducing the stiffness of the moving system. This is effected by the insertion of the spacing annulus 3 between the members 4 and 5 so that the armature 7 is located in position solely by the magnetic influence of the magnetic structure. The members 4 and 5 are of magnetic material and their large radial width compared with that of the ring magnets 1 provides, in effect, an increased radial width for the ends of the ring magnets 1 adjacent the armature 7 so that a greater tolerance for the diameter of the armature 7 and for that of the spacing annulus 3 is allowed. In the embodiment described with reference to Fig. 2 (not shown), which is designed to function as a receiver, the resonant frequency is raised to widen the range of frequencies over which it is sensitive by increasing the stiffness of the moving system. The spacing annulus 3 is omitted and the armature 7 is clamped between the members 4 and 5. Specification 705,330 is referred to.

Title: Apparatus for returning a yarn end into an open end spinning machine
IPC: D01H4/50
Filed: 1967-08-18
Abstract: 1,205,031. Open end spinning. MASCHINENFABRIK RIETER A.G. 18 Aug., 1967 [24 Aug., 1966], No. 38195/67. Heading DID. In an open end spinning machine wherein a yarn reserve is created to be fed back to the spinning chamber 32 in the event of the yarn becoming detached from the spinning chamber surface or on starting up spinning, the reserve is created by increasing the length of yarn path between the spinning chamber 32 and take up means 40 while spinning is in progress and at such a rate that the yarn count is not changed substantially. As shown in Fig. 3 the yarn is delivered through a tube 37 pivoted to the chamber delivery tube 36 and biassed away from the vertical by a spring 41. Normally the tension in yarn 38 balances the force of spring 41 and maintains tube 37 in the position shown in full lines. When the yarn tension drops tube 37 is drawn against a stop 42 and a switch 43 is closed. In consequence a solenoid 46 is operated to move an armature 47 which is linked to tube 37 and slides in a cylinder 48. Thus tube 37 is drawn into an upright position and the reserve yarn length created is sucked back into the collecting chamber by the suction applied to casing 31'. The motion of tube 37 to the vertical and its subsequent return to its normal position is controlled by a valve 50, a throttle 51 and an opening 49 in cylinder 48. In another embodiment (Fig. 2 not shown), the lengthened yarn path is obtained by passing the yarn about a pin displaced from the straight line path of the yarn; the pin being retractable on yarn slackening. In Figs. 4 and 5 not shown the yarn passes along a series of tubes two of which are telescoped together on yarn slackening to produce a shorter path. In the embodiment of Fig. 5 the collecting chamber is stationary while a yarn gripping device associated with the delivery tube rotates. In Fig. 6 not shown, the yarn path is defined by an elastic tube which is normally stretched to provide a long yarn path but is released on yarn slackening to form a shortened path. In Fig. 7 not shown the path lengthening device consisting of a pivoted lever which deflects the yarn, is mounted between the doffing rollers and the spooling device and a further solenoid is provided to separate the doffing rollers on yarn slackening to allow the excess length of yarn to be drawn into the spinning chamber. An electrostatic spinning arrangement is shown in Fig. 8, the collecting chamber 84 being regatively charged with respect to the positively charged sliver feeding rollers 83. In addition to the solenoids operating the yarn path shortening lever 91 and opening doffing rollers 89 a further solenoid is operated on yarn breakage to pivot a suction tube 96 under chamber 84 so as to draw back the slack end of the yarn. A detailed description of the solenoid means for pivoting lever 91 is given.
