Title: Production of bulky yarn
IPC: D02G1/02
Filed: 1971-12-17
Abstract: 1373778 Bulk yarn TEIJIN Ltd and TEIJIN MODERN YARN CO Ltd 17 Dec 1971 [19 Dec 1970] 58645/71 Heading DIF A method of producing a bulk yarn having controlled residual torque comprises subjecting a thermoplastic synthetic filament yarn to the steps of twisting, heat-setting on a first heater, and untwisting, and either continuously or not feeding the yarn into a second heater while rotating it by means of a fluid nozzel and reheat-setting the yarn in the second heater, the yarn being maintained in a substantially relaxed state e.g. tension less than 0.07 gm/ denier, during the rotation by the fluid nozzle and the reheat-setting by the second heater. In a preferred embodiment, a filament yarn 2, e.g. polyamide, polyester, acrylic, acetate, is withdrawn from a bobbin 1 and passed through heater 4, which may be a curved contact heater, and fed to a false twist spindle 5. The false-twisted yarn is then fed through a heater 7 to a fluid twisting nozzle 8 and is wound on a package 11. The fluid twisting nozzle 8 is preferably of the type directing a pressurised fluid, e.g. air, nitrogen, carbon dioxide, steam, at right angles to the yarn path and tangential to the yarn axis. The second heater 7 is preferably of a type providing contact only at the inlet and outlet thereto, e.g. a pipe heater, with or without an axially extending slit. The fluid nozzle 8 may twist the yarn in the same direction as the false-twist spindle 5 or in the opposite direction depending on the result to be achieved. At a critical point, a non-torque yarn is produced. Many examples are given in which combinations of parameters are varied. The parameters involved are, the temperatures of the first and second heaters; type of second heater; number and direction of false-twists; direction of fluid nozzle twisting; fluid used; angles at which yarn enters and leaves fluid twister; distances between second heater and fluid nozzle, and between fluid nozzle and take-off means; Reynold's number of the fluid; overfeed rates of yarn to spindle 5 and fluid nozzle 8; speed of yarn; and type of yarn.

Patent GB-643482-A (GB)
Abstract: 643,482. Thermal switches. NEWELL, R. E. July 30, 1947, No. 20675. Convention date, Jan. 13, 1945. [Class 38(v)] [Also in Groups XIII and XXIX] A flame-actuated device which shuts off the gas supply to a main burner when an associated pilot burner is extinguished, comprises a valve 29 operated by one end of an arm 3, the other end of which is fixed to one end of a metal tube 1 which is approximately parallel to the arm 3 and is heated on one side only by an adjacent pilot burner 8, the tube 1 being composed of a material, e.g., a chromium-nickel alloy, having a high coefficient of expansion and low coefficient of heat conductivity so that heating by the pilot burner bends the tube 1, and causes the arm 3 to open the valve. In the form shown, a second arm 4 which carries one of a pair of switch contacts 14, 17 is also fixed to the end of the tube 1. This tube is welded to a supporting tube 2 of ordinary drawn steel. The arm 3 has an enlarged head which is welded to the end of the tube 1. The burner parts may direct the flames normally or tangentially to the surface of the tube 1. In the latter case, the burner 8 may be rotatable about its own axis so that the opposite side of the tube 1 may be heated.
Patent GB-774788-A (GB)
Abstract: 774,788. Ignition systems ; timing ignition; switch arrangement. NIEDNER, B. June 12, 1953, No. 16322/53. Class 7 (4). [Also in Group XXXVII] In an ignition system comprising an ignition coil 7, Fig. 3, energized from a battery or generator over an engine driven switch 2 constituting a time limiting means there is provided an additional time limiting means, such as a resistance or engine actuated contacts which limits the duration of ignition when the time of connection of the additional means is less than that provided by the switch 2. A condenser 1 is charged by the battery 3 across the switch 2, which latter upon completing the discharge circuit of the condenser 1 enables current to flow through a relay coil 5 and the variable or fixed resistance 4 to energize the former and hence close contacts 6 thereby permitting battery current to flow through the primary of the ignition coil 7. When the condenser discharge ceases the contacts 6 open to effect ignition; the time for condenser discharge and therefore of ignition coil energization may be regulated by adjusting the resistance. The arrangement of the contacts 6 prevents the coil from being permanently connected to the battery at any time. To obtain ignition when the contacts 6 close instead of open the relay coil 5 is replaced by the ignition coil. In a modification, the resistance is dispensed with and the constant time of energization of the ignition coil is achieved by means comprising a disc 10, Fig. 4, rotatably mounted on a cam shaft 8 and coupled thereto by a spring 11 and a pawl 9 which intermittently engages a projection on the disc 10 so that the latter is held against rotation and the spring 11 is tensioned until a cam 12, also on the shaft 8, releases the pawl 9 and allows the spring to rotate the disc 10 until it is engaged by another pawl not shown ; during such rotation contacts 13 are closed by a cam, not shown, on the disc 10. Continued rotation of the shaft enables cam 12 to release the second pawl whereupon the disc returns to the initial position. In another modification, a spring 15 Fig. 5, loaded by a weight 14 is flexed by a rotating cam 16 and during its recoil closes contacts 18. If the engine speed is low and the spring undamped the contacts 18 may be made and broken several times before the spring is re-engaged by the cam. Since, in all the above embodiments the time of ignition coil energization is constant the engine speed cannot exceed a given value.

Title: An apparatus and method for generating a glow discharge
IPC: H01S3/097
Filed: 1978-11-24
Abstract: This invention provides a laser or high voltage switch which has two spaced apart main discharge electrodes 14 which define between them a main discharge gap 24, a discharge inducing member 16 that is of an insulating material and which provides a planar or curved trigger discharge surface adjacent the electrodes and partially or completely bridging the main discharge gap, and an auxiliary conductor 30 on the other side of the discharge inducing member to the main discharge electrodes and capacitively coupled to one of them by a distributed stray capacitance, such that when an excitation pulse is applied across the main discharge electrodes an initial capacitively initiated low order trigger discharge occurs onto the trigger discharge surface, and preferably across the surface from one main discharge electrode to the other. This trigger discharge photo-ionises a gas in the main discharge gap to cause a glow discharge between the main electrodes. The auxiliary conductor may be shielded by a shielding member to predetermine the capacitive coupling between the conductor and electrodes. <IMAGE>

Title: Current dividers for measuring transformers
IPC: H01F38/30
Filed: 1980-05-02
Abstract: A current divider is used in a measuring transformer for potential- free measurement of currents and comprises a metal strip 1 which is originally flat and from which a web portion 4 and two strip portions to form shunts 6 and 7 are cut. The shunts 6 and 7 are shaped to form at least one loop with limb portions 12, 13 and 14 and the web portion 4 forms, as the measuring conductor, a circular ring 8 and two supply conductors 9. Two current rails 10 and 11 of an electricity meter carry the measuring current to the measuring conductor 4 and the parallel shunts 6 and 7. The current flowing in the measuring conductor 4 is evaluated by the measuring transformer for the purposes of determining the total measuring current. The ratio between the cross-sections of the measuring conductor 4 and the shunts 6 and 7 determines the measuring range, with the measuring transformer remaining the same. Calibration can be effected by removing material from the current divider. <IMAGE>
