Title: Process for the production of crimped yarns and products obtained
IPC: D02G1/00
Filed: 1961-08-17
Abstract: Polyolefin, especially polypropylene yarn, at least partly formed of stretched continuous filaments, is crimped by subjecting the yarn to the action of a swelling agent, in the form of vapour or mist at a temperature near the boiling-point of the agent, for less than 20 seconds.  Suitable swelling agents are aromatic hydrocarbons, e.g. toluene, hydroaromatic hydrocarbons, e.g. cyclohexane, decalin and tetralin, and chlorinated hydrocarbons, e.g. carbon tetrachloride, dichloroethane, tri- and tetrachloroethylene and chlorobenzene.  The yarn is passed through a chamber containing the swelling agent under negligible tension.  The yarn may be twisted prior to the swelling treatment, and may be heat-treated, e.g. in a steamoven, subsequent to it.  The crimp obtained is 20 to 100%, preferably 30 to 45%, and is irregular.  In an example, isotactic polypropylene yarn of 600 den., previously drawn 5,5 times its original length, travels in a path in the form of an acute V through a vertical cylinder, filled with trichloroethylene vapour.  The top of the cylinder is open, and cooled by water, the bottom is connected to a container of boiling trichloroethylene.  After an immersion time of 1 second, the yarn is of 960 den. and has a 37,5% crimp.  Subsequent treatment by steam at 140 DEG C. for 1 hour stabilizes the crimp against tension.

Title: Improvements relating to fuel-injection pumps
Inventor: DINGLE WILLIAM ROY
IPC: F02D1/00
Filed: 1954-10-15
Abstract: 768,732. Engine stop-gear. DAVEY, PAXMAN & CO.,. Ltd. Sept. 15, 1955 [Oct. 15, 1954], No. 29794/54. Class 122 (4). [Also in Group XXVIII] A fuel-injection pump for an internal combustion engine has means operated by a speedresponsive device when the engine speed exceeds a predetermined amount to hold the plunger in or near its maximum lift position so that it ceases to deliver fuel and the engine is thereby stopped. In the block-type pump shown for a multi-cylinder engine, recesses 6 in pins 1 slidable in bores 2 in the casing 3 are engaged by leaf-springs 7 secured to a common shaft 9 extending through the casing and carrying an arm 10 biased by a coil-spring 11 to rotate the shaft in a direction to urge the pins 1 toward the plunger tappets 5. The arm 10 is held in its loaded position by a pin 10a thereon engaged in a notch in a latch 13 secured to a shaft 14 carrying a trip finger 28. A centrifugally operated device comprising a spring- loaded plunger 16 slidable in a carrier 17 is incorporated in the coupling 26 between the engine drive and the pump shaft 27. When the engine speed exceeds a predetermined amount the plunger 16 moves out sufficiently, against the force of the spring 18, to strike the trip finger 28 and release the latch 13, whereby the shaft 9 is rotated to press the pins 1 against the tappets and as each plunger approaches its maximum lift position the corresponding pin enters a slot 29 therein and prevents its return. The engine is thus starved of fuel and consequently comes to rest. The loading of the spring 18 and thus the maximum engine speed can be varied by adjusting the nut 19. In a modification the centrifugally-operated device comprises a spring-loaded weight pivotally mounted on a rotary carrier.
