Abstract: A device, to be incorporated in a spinning frame and including supply rollers for the input of a sliver, a sliver control and drawing station for transforming said sliver into a yarn, and a yarn winding outlet station, comprises on the one hand, between the control and drawing station and the yarn winding outlet station, detector means for detecting the presence of the yarn, and, on the other hand, sensitive means responsive to said detector means for stopping the sliver feed by the supply rollers in case of absence of yarn as detected at the outlet.

Abstract: Edge-reinforced packing is provided for steam service, with wire-reinforced secondary yarns on carriers driven along one or more diagonal tracks of a braiding machine to provide edge-reinforcing which reduces valve stem abrasion while providing sufficient resistance to high pressure, high temperature steam leakage. Wire-reinforcing only the edges of the packing minimizes the amount of reinforcing wire necessary to counteract high pressure steam and thus minimizes valve stem wear. An offset, alternating braid embodiment further reduces wire usage at the packing edges, while at the same time providing complete circumferential reinforced sealing around the valve stem. In cases where the offset braiding results in voids in the steam barrier produced by the reinforced braid, keystone-resisting technology corrects this problem. In one embodiment, the packing is a non-asbestos packing which eliminates both hardening and packing disintegration normally associated with so called "plastic-core" packings.

Abstract: This invention relates to a procedure for splicing yarns, whether textile or otherwise, with a joint made by coupling two single untwisted yarns and thereafter retwisting them, wherein the single yarns are untwisted beyond a substantially nil twist value and are then coupled and retwisted so as to impart to the single yarns a desired twist at least the same as the twist comprised in the original yarn, the untwisting phase being carried on beyond the nil value until a negative twist value has been imparted which is equal to at least 15-20% of the initial twist value comprised in the single yarn, and the value of the negative twist being at least in proportion to the desired reciprocal thrust induced between the yarns at least in the transitory phase when the fibers are parallel to the axis of the single coupled yarns during retwisting.The invention also relates to a splice made by the above procedure.

Preferably, the support plates also incorporate a plurality of aligned shaft receiving holes, thereby enabling the support system to accommodate spools of alternate diameters, as well as spools of any length. Furthermore, spool rotation control means are provided along with a universal securement system for mounting the spool support system in any desired location.

Abstract: Improved multistrand Rutherford-type superconducting cable (42) is produced in a flattened form with two layers of helically wound strands (33) and in which the strands are alternately twisted about their lengths equally and in opposite directions to provide a flat cable with improved stability. In particular, the cable (42) is made by guiding multifilament wire strands (33) from spools (32) on a rotating turret (11) to a fixed tapered forming mandrel (22) where they are wound diagonally around the mandrel and then rolled into a flattened shape. The spools (32) are located around the periphery of the turret and are rotatable about axes in a plane parallel to the turret (11) to unroll the wire. Sprocket assemblies (48 and 49) are driven by drive chains (68 and 76) to rotate alternate spools (32) equally and in opposite directions relative to the forming mandrel (22) so that the wire strands (33) are twisted prior to being wound on the mandrel (22).

Abstract: A steel cord for reinforcing rubber is made by twisting a plurality of strands each made by twisting a plurality of element wires. The cord and the strands are twisted in the same direction. The product of the twisting ratio of the cord and that of the strands, the elongation coefficient of the cord and other factors are determined so that the rubber penetration and the rigidity and tenacity of the cord will be suitable for the carcass cord of steel radial tire.

Abstract: In a process for producing packages used as feeding packages for twisting, onto which two prestrengthened yarn components are wound side-by-side as a double yarn, it is provided that, when one of the two yarn components breaks, the other yarn component is cut in such a manner that the lengths of the two yarn components are at least approximately the same. As an alternative, it is provided that, when one yarn component breaks, the partially completed package is stopped, before the broken end has moved onto the partially completed package.

Abstract: A thread cabling machine is provided with an improved regulator device (or cabling head) in which each work station consists of a DT unit similar to a double-twist unwinding spindle which enables two elementary threads to be united by twisting. One of the threads forms a balloon which surrounds the bowl inside which the spool of the second thread is disposed. The two threads are joined on a cabling head consisting of a unit comprising two pulleys mounted on a support driven rotationally by the balloon of the thread. The invention is characterized in that the eye carrier plate, disposed under the rotary pulleys and enabling the threads to be brought to the pulleys, is provided with a frustoconical part enabling the thread forming the external balloon to wind around a reserve groove forming a radius "r" relative to the axis X--X of the unit.

Abstract: A safety belt retraction apparatus is provided for use in a vehicle having at least one door and a chassis. The apparatus includes a safety belt retractor mechanism mounted on the vehicle door, and having a reel about which the webbing of the safety belt is wound. The reel is adapted to take up and let out the webbing. The safety belt retraction apparatus further inlcudes a resiliently compressible bellows of blow-molded plastic. The bellows is mounted at one end to a housing containing the retractor mechanism, and has an opposite web-engaging free end adjacent the reel. The bellows is dimensioned so that its free end is spaced from the reel during initial take-up operations. Thereafeter, upon continued winding of the webbing about the take-up reel, the free end of the bellows engages the webbing, and with continued winding is compressed so as to exert a friction force on the webbing during continued take-up. The friction force precludes loose winding of the webbing about the reel.

Abstract: An open end spinning machine and an associated traveling sliver can replacement carriage are provided with cooperating components for automatically replacing empty sliver cans at the spinning positions of the machine with full sliver cans and threading up the sliver for spinning resumption. An openable and closable sliver guide is provided at each spinning position in association with a sliver monitor which recognizes the presence and absence of sliver in the guide. A signal transmitter at each spinning position produces a can replacement signal when the monitor recognizes the absence of sliver in the guide. A program controller is associated with a signal receiver on the carriage to actuate exchange of the empty sliver can at the signaling spinning position with a full sliver can from the carriage.
