Abstract: 1371955 Forming reserve windings ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 16 May 1972 [7 June 1971] 22868/72 Heading D1J Yarn is wound on to a rotating former by making a loop in a yarn extending between two sources of supply, introducing the loop to the former and then simultaneously building- up from the loop two windings on the former in such a manner that the two windings occupy respective portions of the length of the former with no overlap between them and such that the ends of the two windings extend from the resulting bobbin in the same direction. In Fig. 3 the full package 12 has been removed from the winding station and replaced by an empty tube 11. A loop of yarn is then formed, this loop extending from (a) the yarn supply and (b) the previously wound package 12. The loop arm from the supply is placed in a yarn traverse mechanism 14 and the loop arm 8 from the previously wound package is placed in a gripper 4, 6, Fig. 2, carried by the cradle arm 1'. The loop is then fed between the empty tube 11 and the drive roller 13 so that a main winding and a reserve winding are simultaneously formed in a non- overlapping manner. When sufficient yarn has been wound for reserve purposes, the yarn 8 is cut. The tube 11 is supported between cradle arms 1', Fig. 2, on one arm of which is mounted the gripper 4, 6 for guiding the yarn that is to form the reserve winding. The gripper comprises a pair of jaws 4, 6 forming a wedgeshaped space into which the yarn 8 from the previously wound package can be placed. The jaws are mounted on a pin 5 and biased towards each other by a spring 7. A step 9 at the lower end of jaw 4 prevents the jaws from clamping the yarn 8. The reserve winding is laid in groove 10 or on a roughened surface.

Filed: 1970-05-12
Abstract: 1314071 Fluid dampers INTERNATIONAL BUSINESS MACHINES CORP 12 May 1970 [14 May 1969] 22928/70 Heading F2S [Also in Division F1] An hydraulic device for positioning a load comprises an assembly of piston and cylinder units 1 having an output shaft 2 carrying the load and a damper device 3 operable, firstly, to damp the final movement of the load and, secondly, accurately to locate the load in the desired position. When the load is to be repositioned, the desired cylinders are pressurized through lines 17, the load being initially prevented from moving. During this initial operation the pistons of some cylinders extend while others contract and, additionally, a piston 5 in a cylinder 6 of the damper device 3 is moved from its central position in a direction opposite to the eventual direction of movement of the load. Thus when the load is released the damper piston 5 is forced by the load towards its central position, this movement being damped by liquid having to flow through orifices 15 from one side of the piston to the other. The piston 5 is then returned to its exact central position by pressurizing a cylinder 12 so that the rods 10 of pistons 11 bear on plates 8, 9 fixed to the piston-rod 7. A liquid pressure source 16 is provided for making up liquid wet from the cylinder 6. The exact central positioning of the piston 5 may be effected by urging the conical tip (26) of a piston (25) into engagement with a V-groove in the periphery of the piston 5.
