Title: Improvements in or relating to the collection and liquid treatment of yarn
IPC: D02J1/22
Filed: 1944-02-01
Abstract: <PICT:0577604/IV/1> <PICT:0577604/IV/2> Yarn is collected as it is delivered from a stretching operation by drawing it forward by means of a pair of intermeshing swifts driven at a peripheral speed slightly greater than the linear speed of the yarn as it comes from the stretching operation and feeding it to a collecting device of the type known as Topham box in which it is wound into the form of a cake.  Referring to Fig. 1, yarn leaving the stretching chamber 1 is drawn forward by a pair of intermeshing swifts 7 driven at a peripheral speed slightly greater than the linear delivery speed of the yarn, and fed to the rapidly rotating box 12 through a funnel 11 down which a stream of liquid, e.g. water, is passed.  The funnel 11, which is rapidly traversed up and down the axis of the box, has steeply sloping conical walls and a stem with a lower rounded edge in order to facilitate initial threading of the collecting device. The box 12, in which accumulates a hollow cylindrical cake of twisted yarn, is perforated to allow the liquid entering through the funnel to escape under centrifugal force.  Subsequent liquid treatment of the yarn-cake, such as saponification in the case of a cellulose ester yarn, may be effected by rotating the box and supplying treating liquid to the inside of the rotating cake as shown in Fig. 3.  To support the cake during treatment, lease bands or cords 31 may be threaded through the yarn and secured to the walls of the box, or an expanding swift with a perforated barrel may be inserted in the cake.  The cake may be subsequently unwound by inserting a former or expanding swift through its core, when it may be removed from the box and mounted for unwinding. Saponification of cellulose ester yarns may, if desired, be effected during or towards the latter stages of collection of the yarn in the box, by employing saponifying liquid, e.g. caustic soda solution containing sodium acetate, to carry the yarn through the funnel into the box.  A cake of dry cellulose acetate yarn may be subjected to a shrinking treatment prior to saponification by immersing the stationary box in a bath of liquid, e.g. methylene chloride and petrol, the cake with an expanding swift inserted in its core being then preferably removed from the box, mounted for rotation, and saponified by supplying saponifying liquid to the perforated barrel of the swift.

Title: Process of drying products produced from aqueous dispersions of organic substances particularly of caoutchouc or caoutchouc like substances by agglomeration upon a base
IPC: C08J5/02
Filed: 1927-01-25
Abstract: 293,061. Anode Rubber Co., Ltd., (Klein, P.). Jan. 25, 1927. Latex, treating.-Shaped articles of substantial thickness produced by immersing a former in aqueous dispersions of organic substances, particularly rubber, are dried by maintaining one side at a higher temperature, and permitting escape of the water from the other side. on which an impervious dried skin is prevented from forming until the article is dry. When the article is dried on metal moulds, the moulds are heated for example by passing heated air through them. by electric resistances, or by induction. The drying on the outer surface may be delayed by maintaining the air at a lower temperature, and moistening it. When porous moulds are employed, the mould may be heated or the outer surface may be at the higher temperature, and the moisture withdrawn through the mould. The article mav also be dried after removal from the mould. The process is suitable for the drying of articles deposited from aqueous dispersions of rubber, gutta, balata, &c., casein, albumen cellulose esters, artificial or natural resins. The articles may be formed by dipping porous moulds, which may be impregnated with coagulants, or by electrophoresis.

Abstract: 1,021,591. Making pipes. LORRAINEESCAUT. Jan. 20, 1964 [Feb. 1, 1963], No. 2408/64. Heading B3A. A thin wall tube made of a hardenable metal on a production line by forming and welding steps, is expanded and then treated by local heating as it passes along the production line. The tube is preferably of large diameter made from high strength steel and is used for conveying hydrocarbon liquid or gas. A length of plate has its edges chamfered by planing and is then cold shaped on a press into a tube. The longitudinal edges are then fusion or resistance welded and the tube is cold expanded by hydraulic or mechanical means. Whilst supported on rollers the tube passes through one or more annular induction heating coils where it is heated to 650-950‹ C., then cooled by an annular jet of fluid and passed through an annular tempering coil. Alternatively the heating may be by combustion. If the weld is disposed upwardly, the tendency of the tube to become oval upon heating due to stress relieving at the weld is compensated by the effect of gravity.

Abstract: 607,071. Coaster hubs. BENDIX AVIATION CORPORATION. Jan. 24, 1946, No. 2427. Convention date, Feb. 9, 1945. [Class 136 (ii)] [Also in Group XXXIV] In a hub brake-mechanism, backward movement of the wheel driving member compresses axially a block of rubber or like resilient material causing it to expand radially to apply a friction member to the interior of the hub. As shown, the friction member comprises a split sleeve 15 anchored by engagement of slots 19 with projections 18 on a pair of halfdiscs 16, 17 which bear on projections 21, 22 from the fixed bearing member 7. A slidable disc 26 with lugs 27 engaging slots 28 in the sleeve 15 bears on a block 25 of rubber, which has a recess 30 to receive the anchoring projections 21, 22. Forward drive is transmitted to the hub 9 from the sprocket 5 through the member 2, a nut 29 and interengaging teeth 31, 14 on the nut and hub. Upon backward rotation of the sprocket, the nut 29 is moved axially to compress the block 25, thus expanding the sleeve 15 into engagement with the hub. Frictional drag is applied to the nut to ensure its axial movement, either by cutting the sleeve at 34 to form a tongue 35, which bears on the nut or by a spring ring secured within a groove in the nut and bearing against the sleeve 15. The nut is held from rotation in the braking position by the interengagement of teeth 32, 33 on the nut and disc 26.

Class 7(v) In an engine starter having a reversible motor 14 connected to an engine-driving member or jaw 12 by speed-changing means, comprising in combination, an intermediate spindle 26 coaxial with the motor, main reduction. gearing 32 forming a permanent drive from the intermediate spindle 26 to the jaw 12, a main unidirectional clutch 54 which connects the motor directly to the spindle 26 to rotate it as one with the motor shaft 18 when the motor turns in a given direction, the main clutch 54 being adapted to slip when the motor is reversed, and an auxiliary reduction gearing 46 which transmits drive from the reversed motor to the spindle 26 and thence through the main reduction gearing 32 to the jaw member 12, the spindle 26 being turned in the same direction as before but at a reduced speed, the auxiliary reduction gearing 46 is arranged to include an auxiliary unidirctional clutch 56 adapted to slip whenever the motor turns in the given direction in which it transmits power directly to the intermediate spindle through the main unidirectional clutch 54. In order to prevent damage resulting from a hydraulic lock in the cylinders of an engine, the starter motor 14 firstly turns the engine at a speed lower than starting speed; the motor 14, but not the .engine, turning in the reverse direction from that obtaining during starting. When motor 14 is running in reverse, a gear 48 on the motor shaft 18 transmits mction through the auxiliary reduction gearing 46, auxiliary clutch 56, located between the output gear 50 of gearing 46 and the spindle 26, to drive the latter and hence jaw member 12. The spindle 26 has a pinion 24 secured thereto and is housed within the shaft 18 whilst the member 12 is driven from pinion 24 through the main reduction gearing 32, a multi-plate clutch 34, splined nut 36 and screw shaft 38. When the motor 14 is energized to rotate in the starting direction the shaft 18 drives spindle 26, by means of main clutch 54, and hence rotates member 12 at normal cranking speed.
