Abstract: 1436748 Simultaneous drawing and false twisting of polyester yarns TEIJIN Ltd 16 Aug 1973 [17 Aug 1972] 38836/73 Heading D1F In a process for producing polyester textured yarn comprising simultaneously drawing and false twisting an undrawn polyester yarn using a heater and false-twister disposed between feed and draw rolls, the birefringence #n of the undrawn yarn and the draw ratio DR are adjusted to meet the following conditions:- The above process is said to produce a textured yarn of uniform quality especially in respect of dye take-up. The birefringence #n is preferably in the range 0.01-0.025. In a preferred embodiment of the process the undrawn yarn is subjected to an aging treatment prior to drawing and texturing. The heater is maintained at a temperature in the range 160-210‹C and the feed rolls may also be heated to a temperature in the range 60-120‹C, the yarn being in contact therewith for at least 0.05 seconds. The draw ratio DR is preferably in the range 2.2-2.8 at the speed of processing is preferably in the range 75-600 m/min. In a preferred embodiment, the yarn is caused to pass round at least two guides between the false-twister and the draw rolls with a consequent change in direction, with the sum of the angles being in the range 30-270‹. In a preferred embodiment, the yarn is caused to run so as not to make contact with the upstream end of the heater whereby the yarn is preheated by the heater at a temperature in the range 60-150‹C. Various methods of starting the process are described to reduce breaks during start-up; these methods include starting at a reduced false-twist speed and then gradually increasing to the required value; starting at a reduced draw texturing speed which is later increased to the required value; starting keeping the yarn out of contact with the heater and then bringing the yarn into contact therewith. The process may be carried out continuously by joining leading and trailing ends of subsequent packages to be processed. The yarn may be additionally heat treated after texturing while being allowed to shrink or being maintained at constant length. Various numerical examples are given.

In welding a wire or the like to a body the wire is held rigidly in contact with a surface of the body and the body is ultrasonically vibrated parallel to the surface by means of vibrations transmitted via frictional coupling. To weld a wire 5, Fig. 1, to a plate 6 the wire is held or clamped in an anvil 4 which may have a bore through which the wire may be fed and the plate 6 is arranged between the end of the wire and the tip 3 of an amplitude transformer 2 connected to a transducer 1. The anvil is spring-urged against the plate and tip 3 and the latter is vibrated parallel to the plate vibrating the plate until a weld is formed when the tip slides on the plate. Copper or aluminium wires may be so welded to copper, brass or aluminium plates. In a modification a wire 5 is welded to the bottom 6<SP>1</SP>, Fig. 3 (not shown) of a box-shaped envelope 10 of an electrolytic capacitor using an elongated tip 3 coupled to a transducer and amplitude transformer. An apparatus similar to that shown in Fig. 3 may be used to weld a plate to a wire held by a three-part jaw in the anvil. A wire may be welded to a lug or protruberance on a body and the wire may be at an angle to the surface.

The starting workpiece is an unheated rod cut from stock and during its upsetting, a shank portion is extruded into die 25. After removal by a knock-out pin 26, the workpiece is inserted in a second die 40, Fig. 5, where its upset portion is backwardly extruded by a punch 49 whose conical end is shaped to trap oil in the cavity being formed and thus prevent metal to metal contact between the conical end and the workpiece. An annular bulge 42a is upset on the shank to hold the workpiece in the die during withdrawal of the punch; this bulge is smoothed out when the workpiece is ejected by a knock-out pin 46.

A forehearth 10 containing molten glass 11 has an electrically heated Pt/Rh alloy bushing 12 with a plurality of orifices 13, each having tips 14. Glass fibres 17, Fig. 1, are drawn from the bushing 12 over a roller 23 of a size applicator 22 over a gathering guide 20 by winding on a rotating forming tube 18, driven by a collet 19, while guided thereon by a traversing mechanism 24.  A transformer 31, Fig. 2, which supplies power to terminals 15 of the bushing 12, has a saturable choke 30 in series with its primary winding. The temperature of the molten glass 11 in the bushing 12 is sensed by a thermo-couple 36 which is connected through a corrective unit 40 to a conventional temperature measuring and controlling device 35 to the choke 30 to control the power supplied to the transformer 31.  The corrective unit 40 includes electrically-operated means initially actuated by a switch on the collet 19 drive motor to cause a continuously decreasing "false" temperature reading to be received by the regulating unit such that the unit 40 causes the temperature of the bushing to be increased during a fibre drawing run and also means to increase the apparent temperature reading and hence reduce the temperature of the bushing 10, after a pre-set time or after the stopping of the collet drive motor for any other reason, to a value slightly below the normal starting temperature. A suitable circuit for the unit 40 is disclosed.

Abstract: 1323803 Ball throwing machine D C SWEETON 24 Aug 1971 [24 Aug 1970] 39722/71 Heading A6D A ball throwing machine consists of a box 1 having an air chamber 19 into which air is blown by blower 26 and an upper tray 6 for storing balls, a flexible duct 8 leading from the chamber 19 to a projecting barrel 9 and feeding means 7 to feed balls from the tray 6 to air chamber 19 for transportation along duct 8 to barrel 9. The feed device 7 has a number of pockets 21 and is rotated so that each pocket in turn is brought over an opening 33. This opening is kept normally closed by flap valve 31 due to air pressure in chamber 19, 29, but the weight of a ball on flap 31 is sufficient to cause it to open to release the ball into chamber 29. The ball is then carried by the flow of air through the duct 8 to the breach of barrel 9 where it comes up against a detent means 35 (see also Fig. 4, not shown). Pressure in the duct 8 and chamber 19, 29 then builds up until it is sufficient for the ball to overcome the detent and the air pressure then ejects the ball from the barrel. The detent pressure is adjustable by spring 11 and screw 13 so that the build up of pressure and thus the ejection velocity can be varied and a sleeve 15 movable over relief holes 14 in the barrel 9 can be used for the same purpose. The box 1 is preferably attached to a tubular framework 4, 5 which also mounts the barrel 9 in an angularly adjustable manner so that the trajectory of ejection can be changed.

Abstract: 401,749. Calculating - machines. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Christian, R. A. ; 246, Telford Avenue, Dayton, Ohio, U.S.A.) May 23, 1932, No. 14559. Convention date, May 22, 1931. [Class 106 (i).] A roller on the travelling carriage of a calculating-machine is effective in one direction of movement of the carriage to condition the machine for total-taking and in the other direction to condition it for subtotal-taking. The invention is shown as applied to a machine of the Ellis type. A roller 107 on the carriage rocks a lever 108 connected by a link 112 to a lever 113 freely mounted on a shaft 114 and connected by a spring to a lever 115 secured to the shaft. The shaft 114 also carries an arm 121 engaging a pin 123 on the total key 77 which key is thus depressed when the carriage, moving from right to left, engages the lever 108. The subtotal key is depressed when the carriage is moving from left to right and the roller 107 passes over a lever 124 pivoted at 125 and having a pin 134 which rocks a lever 127 pivoted at 130. The lever 127 is connected to a lever 137 connected in turn by a link 140 to a lever 141 having a flexible connection with the subtotal key 30. After being depressed by the carriage, the total and subtotal keys are held by their latches until released during the subsequent operation of the machine. The Specification as open to inspection under Sect. 91 describes also a machine in which a roller on the carriage depresses the total-taking cam in either direction of travel of the carriage. This subject-matter does not appear in the Specification as accepted.
