Title: Improved apparatus for the production of cabled yarn
IPC: D01H1/10
Filed: 1959-10-02
Abstract: 915,942. Cabling yarns. TEXTILE & CHEMICAL RESEARCH CO. Ltd. Oct. 2, 1959 [Oct. 6, 1958], No. 33514/59. Class 120 (2). Apparatus for cabling yarns, particularly artificial or synthetic yarns for tyres, belts &c. comprises a frame carrying three or more double-twist let-off spindles and a double-twist take-up spindle, guide-means associated with each spindle and adjustable in the line of axis thereof whereby the tensions in the yarns ballooning from the let-off spindles and on to the take-up spindle may be individually controlled, means for collecting the yarns from the let-off spindles and for feeding them to the takeup spindle and a single motor drive for all the twisting units. The cabling twist may be greater or less than and opposite to the singles twist and may be with or without initial twist. The let-off and take-up spindles may be respectively of the type described, and claimed in Specifications 915,943 and 915,944. The apparatus is arranged on bars 1, 8, as shown in Fig. 1; the spindles are offset relatively so that their driving-pulleys 13, 14 are engaged by a belt driven by a motor 11 without the need for idler pulleys. Yarn from each let-off spindle B travels to guide C, and the three yarns converge a guide 17 where each yarn passes over a separate roller 18. The yarns then travel to a delivery-member D and then, via a guide E, to take-up spindle F. Each guide comprises an arm with an eye 15a and a roller 15 with a thread-positioning disc 16; the arm is so mounted that it can be moved along the bar which supports it to vary the size of the balloon; it can also be pivoted between an operative position and an inoperative position where it is retracted to allow ready accoss to the spindle, the arm being held by magnetic means, Fig. 6, not shown, in both positions. Pneumatic means may be provided to assist threading-up the guide. At the delivery element D, Figs. 7, 9, each yarn is wrapped several times around two mutually-inclined rollers 132, 133, travels over a roller 135, and then round a groove of roller 136, over a finger 137 of an electric stopmotion and around a groove of roller 136a. Roller 135 is mounted on an arm 138 pivoted at 139 and biased against the yarn-tension by an adjustable spring 140. Roller 132 is mounted on a shaft extending through a plate 30 and has a brake-drum 134 fitted on the other side. Pivot 139 carries an arm 138A on the other side of plate 130, to which is attached one end of a brake belt 144 fixed at its other end, and having an elastic section 145. Increased tension on the delivery side of the member rotates arms 138, 138A to reduce braking of drum 134.

Title: Hydraulic actuating systems for internal combustion engine poppet valves
Inventor: PARROT DAVID HAMILTON
IPC: F01L9/10
Filed: 1967-07-21
Abstract: 1,224,168. I.C. engine valve gear; hydraulic apparatus. BRYCE BERGER Ltd. July 10, 1968 [July 21, 1967], No.33640/67. Headings F1B and F1P. A hydraulic system for actuating a spring-loaded poppet valve 30, e.g. a dual fuel I.C. engine gas inlet valve, includes a valve actuating plunger 22 movable axially within the cylinder 24 by liquid under pressure acting on its inner end. The plunger 22 has a helical groove 35 which co-operates with a spill port 25 in the cylinder 24 to determine the position of the plunger in which the valve 30 is open. The plunger is angularly adjustable in the cylinder by a sleeve 33 and worm wheel 34 in order to vary the stroke of the plunger. The reduced portion 27 of the plunger co-operates with the bore 28 to cushion motion of the plunger under the action of the spring 23. Actuating liquid is supplied to the inner end of the cylinder 24 through the pipe 32 by a cam-actuated piston 11 having helical edges 13A and 13B and driven by the engine. The piston 11 is angularly adjustable relative to a spill port 14 by a rack 37 to determine the instant and the duration of liquid supply to the valve actuating cylinder 24. To prevent cavitation the cylinder 36 may be connected to the chamber 15, communicating with a liquid supply reservoir, through the non- return valve 17, during the return stroke of the plunger 11.
