Abstract: 1453979 Composite yarns: traverse guide and unwinding unit DU PONT OF CANADA Ltd 15 March 1974 [16 March 1973] 12856/73 Headings D1F, D1J and D1W A method of manufacturing a composite yarn of an elastomeric yarn intermingled with a non- elastomeric multifilament comprises temporarily stretching an elastomeric yarn 10 in a draw zone and false twisting this yarn together with a drawn non-elastomeric multifilament yarn 11 and heat setting the composite yarn at a temperature below that at which the elasticity of the elastomeric yarn would be destroyed. The produced yarn has alternating twist of random periodicity but zero net twist over an extended length thereof. As shown, the false twister 20 and heater 18 are located in the draw zone between rollers 14, 15 and 16, 21, 22. A pre-drawn multifilament yarn may be employed in which case the elastomeric yarn is stretched by being paid out from an unwinding unit, Fig. 2. directly to the rollers 16, 21, 22. The apparatus shown includes an interlacing jet 23 and finishing roller 24 which applies lubricant. Examples are given which relate to a spandex elastomeric yarn and nylon 66 multifilament. The unwinding unit Fig .2 comprises a driven roll 31 and idler 32 which support a package 30, the package being located on a hinged arm 36, 37 by which it can be raised using handle 39. The produced yarn is taken up on a package 26, surface driven by roll 27, and is traversedby a bar 28 carrying an eccentrically mounted "wobbler" 25 over which the yarn passes to superimpose a sinusoidal oscillation on the main traverse motion.

Filed: 1968-03-18
Abstract: 1,194,123. Tensioning wefts; stop motions, shuttleless looms. ELITEX-ZAVODY TEX TILNIHO STROJIRENSTVI, GENERALNI REDITELSTVI. 18 March, 1968 [17 March, 1967], No. 12953/68. Heading D1E. A gripper shuttle loom has two levers 7, 12 acting on the weft, .the lever 7 to pull back the weft after picking and the lever 12 to tension the weft and act as a stop motion feeler. The lever 7 is fixed to a shaft 3 and the lever 1.2 is movable on the shaft 3 against the action of a spring 8 and friction plates 10, 11. After picking the shaft 3 is turned by a cam 5 so that both levers 7, 12 draw the weft into a double loop and a clamp 15 is closed to prevent withdrawal of weft from a spool 18. Continued movement of the shaft 3 causes the lever 7 to pull back more weft and the tension in the weft causes the lever 12 to return to its original position against the force of the friction plates 10, 11. Further movement of the lever 7 may then pull weft through the clamp 15. In the absence of weft tension the lever 12 continues to move with the lever 7 and a projection 16 on the lever 12 operates a stop motion switch 2 which is adjustable in position around the shaft 3.

Abstract: 800,532. Starting low-pressure discharge lamps. GENERAL ELECTRIC CO., Ltd. May 4, 1956 [May 4, 1955], No. 13003/55. Class 38 (4). An A.C. low-pressure discharge lamp 1, or a plurality of lamps in series, used particularly for aircraft flashing beacons, has a high-voltage D.C. pulse applied to its starting conductor 4 from an auxiliary supply to ensure striking of the lamp. The starting circuit comprises an inductor 17 in series with relay contact 18 and resistor 19 connected across D.C. terminals 20, 21 in parallel with relay 24 and switch 25. Closing switch 25 energizes relay 24, closing contact 8 then opening contacts 11, 18, the latter inducing a high voltage pulse in inductor 17 which is applied to conductor 4 of lamp 1. The electrodes 2, 3 are fed from transformer secondary windings 12, 13, the primary 9 being connected across the A.C. terminals 5, 6, in series with a resistor 10 to reduce the voltage when running. A capacitor 14 connected between terminal 6 and a tap on the ballast choke 7 improves the power factor; also, the initial charging current causes an increased voltage to be induced across choke 7, thus further aiding the starting conditions. In another embodiment (not shown) a separate capacitor connected across the supply improves the power factor, and capacitor 14 is adjusted to give a smaller starting pulse. An alternative starting circuit (also not shown) utilizes a capacitor discharging into an autotransformer.

Title: Rotary positive-displacement pump
IPC: F04B49/00
Filed: 1970-03-19
Abstract: 1298394 Rotary positive-displacement pumps TOYODA KOKI KK 19 March 1970 [1 April 1969] 13266/70 Heading F1F An hydraulic pump has spring-loaded abutments 23 slidingly engaging with a cam ring 20 fixed to a rotary shaft 18, which is provided with suction and delivery channels 27, 29 that communicate with recesses 26, 28 in said ring. Notches 23a give the working fluid access to the outer sides of the abutments; and grooves 31, 32 at the leading edges of the recesses minimize pressure pulsations. The working fluid is stored in a reservoir 34. Discs 14, 15 are loaded by pressure transmitted from the channel 29. The out-going fluid is directed from the channel 29 to a delivery port 41 by way of a passage 39 and the throat 47 of a Venturi passage formed in a spring-loaded valvemember 44, the pressure at said throat being transmitted to a chamber 44a through passages 48, 49. In accordance with the pressure differential between its ends the member 44 allows a proportion of the fluid to return to the reservoir by way of a port 51 and thus renders the flow through the port 41 substantially constant. When a pilot pressure-relief valve comprising a spring- loaded ball 53 opens the member 44 is displaced so as to increase the flow through the port 51. A second embodiment, Figs.4 and 5 (not shown), differs mainly in that the Venturi passage is located apart from the valve member. A third embodiment, Figs.8 to 10 (not shown), differs chiefly in that a reservoir for the fluid is either mounted on top of the housing 10 or situated separately from the remainder of the pump and the fluid flows from the reservoir to the channel 27 by way of the port 51, the valve member being generally similar to that shown in Figs.2 and 3.
