Title: Improvements in or relating to methods and apparatus for the manufacture of false twisted single or multiple filament synthetic yarn
Inventor: GILCHRIST REGINALD SELBY
IPC: D02G1/02
Filed: 1961-07-28
Abstract: 952,509. Crimping and tensioning yarn. KLINGER MANUFACTURING CO. Ltd. Sept. 6, 1962 [July 28, 1961],No.27581/61. Headings DID and DIF. In crimping continuous filament synthetic yarn (by continuously drawing the yarn from a supply bobbin, passing it through a healing zone to apparatus e.g. a tubular spindle with a hollow head carrying one or more transverse yarn-engaging pins or sets of overlapping friction discs, which applies false-twist to the yarn by reason of frictional engagement therewith, and winding on a driven reel) the yarn is subjected to "drag" by causing it to be inflected in passing over and in contact with a friction surface disposed between the heating zone and the false-twisting apparatus whilst permitting the twist to run back and through the heating zone. "Drag" may also be imparted to the yarn between the supply bobbin and the heating zone. The value of the drag may differ on opposite sides of the heating zone and twist is prevented from running back to the supply bobbin. As shown, yarn drawn from bobbin 15 passes through an eye 16 to a drag imparting device 17 e.g. a gate tensioner or a magnetically or frictionally and yieldingly restrained pully, through eye 18, along the bottom of a groove 20 in a heated body 19, through eye 22 to another drag imparting device 23, through eye 24 and false twister 21 and feeding rolls 10 to a take-up spool 13. The device 23 is in the form of a waisted, ceramic body secured by a bracket (25) with its axis extending in the general direction of travel of the yarn and one or both eyes 23 and/or 24 may be adjusted therearound to vary the amount of drag. A modified device 23, Fig. 3, comprises a bent portion 28 and eye 22 is adjustably carried by bracket 25. An alternative drag imparting device (not shown) comprises a rotated pulley (similar to device 17) in a peripheral groove of which slip occurs between yarn and pulley surface and thus imparts frictional drag to the yarn. Specifications 908,112, 933,438 and 946,350 are referred to.

Filed: 1945-10-19
Abstract: 607,708. Road vehicles; bodies; springs. BAGHUIS, L. H. Oct. 19, 1945, No. 27589. Convention date, March 31, 1942. [Classes 108 (i), 108 (ii) and 108 (iii)] A motorbus or like vehicle has a self-supporting body to which the road springs carrying the wheels are attached direct. The springs, preferably vertical helical springs, may be located within the hollow walls of the body, and hydraulic damping means may be provided. The road wheels 7, 8 are carried by a yoke 9 pivoted at 10 to the bottom end of a cylindrical member 11 slidable vertically within the body walls against a compression spring 15. Slidable within the cylinder 11 is a piston 13 mounted rigidly on a fixed rod 17. The cylinder 11 below the piston 13 may be filled with oil, and during an upward movement of the cylinder the oil escapes through aperture 19, normally closed by the spring-loaded disc valve 20, up the hollow rod 14 to the expansion chamber 18. During the return movement of the cylinder, the valve 20 is closed by spring 13 and the oil can return only through a small vent 21 in the disc valve, thereby damping the spring action. To prevent the yoke 9 from turning about the cylinder 11, it is provided with a pair of connections 23 to the floor member 24. In a modification, Fig. 4, the yoke 25 carries only a single road wheel 7, the yoke being pivoted to the vehicle body at 26; the wheel 7 may be steerably mounted in the yoke, in which case the yoke is shaped as indicated in dotted lines at 27.
