Abstract: Alternate-twist plied yarns, wherein a secondary strand for providing a special effect is plied with at least two alternately, false-twisted primary strands, are made by converging the secondary strand with the primary strands downstream of the point at which the primary strands are converged. The nodes at the twist reversal points for the secondary strand are displaced with respect to nodes of the primary strands. Improved effectiveness from the secondary strand in the plied yarn, such as better antistatic performance, can be realized. Where a node of a secondary strand overlaps a node of the primary strands, whether or not the node centers are displaced, a preferred configuration is one wherein the secondary strand forms a node by wrapping around only one of the primary strands in a portion of the primary node.

Abstract: The present invention relates to an open-end spinning system and more particularly to a method and an apparatus for stopping and starting the spinning operation of the open-end spinning system in such a way that the end portion of the spun yarn of the previous spinning may be used as it is as the piecing-up end yarn for the following spinning operation. The apparatus of the present invention, includes means for positively braking the combing roller for concurrently and suddenly stopping the rotation of the combing roller and the feed roller and means for taking the end portion of the spun yarn out of the spinning rotor, maintaining the taken out portion in a deflected state with the end of the yarn disposed within a spinning tube, and releasing the yarn at the restart of the spinning operation so that said end portion may be injected into the spinning rotor.

Abstract: An illustrative embodiment of the invention is directed to a thermally insulated exhaust duct structure. In this regard, a typical duct comprises an inner stainless steel conduit and one or more sheets of highly-reflective material that are spirally wrapped around and spaced outwardly from the outer surface of the conduit. The adjacent layers of the sheet material, moreover, are spaced from each other a predetermined distance through corrugated strips that are fastened to one side of the sheet material. Thus, when wound about the conduit in an overlaying relationship, the corrugation peaks bear against the sheet of material that is immediately below and thereby estabish a spacing between adjacent layers that is at least equal to the depth of the corrugations. Other features of the inventon include an outer protective stainless steel casing that fits over the spirally wrapped insulating sheet and a roof penetration for the duct structure.

Abstract: Means for measuring the flow of a stream of fluid and the resistance to said flow. The means can be powered by the fluid whose flow is being measured. First axis motor means moves a chart in response to total flow, and second axis motor means moves marker means on said chart in response to variations in backpressure caused by resistance to flow out of the means. Examples are measuring the muscular response of the urethra and of the bladder.

Abstract: An instrument for measuring wind velocity, utilizing impact wind pressure against a movable vane. A spring is used as a mechanical reference and, as such, balances the impact wind force generated against the vane. Flexible means are used to transfer vane motion to a circular indicator disc, which is calibrated in wind speed. Design of kinematic geometry, as well as a unique, non-linear, spring arrangement are employed to counter the square law wind force. Such employment is essential to prevent crowding at the low end of the speed-indicating scale, while maintaining practical full scale values, in a highly sensitive instrument.

Abstract: An air bearing for a spinning- or a twisting ring suitable for use in the textile industry has a stator which is mounted on a spring-loaded damping absorber system. The absorber has a linear spring-curve in response to small deflections which rises progressively as the stator is further deflected.

Abstract: Mechanism for supplying sliver to a resolving roller is adaptable to slivers having different average staple fiber lengths by selectively engaging a plurality of clamping members to provide a selectable nip line between a sliver supply roller and its cooperating member at different distances from the resolving roller corresponding to the sliver average staple length. Either the selected clamping member or the counter member is the supply roller. Selection of the desired nip line may be made by moving one or more clamping members and the counter member relatively, by selection of one of a plurality of feed nozzles, or by selective positioning of a movable feed nozzle. The nip line selection may be effected at individual spinning stations or simultaneously for a plurality of spinning stations.

Abstract: A yarn of thermoplastic synthetic fibers is false twisted and during the false-twisting operation the number of false twists being imparted to the yarn is estimated with high accuracy. The estimation of the number of false twists is carried out by measuring, in a section within the twisting zone of the false-twisting apparatus, the speed of the yarn being processed under a normal operational condition and by the estimated number of false twists the yarn is advantageously quality controlled.

Abstract: The apparatus comprises at least two spaced parallel discs having a relatively small thickness and mounted on one rotary shaft, and an intermediate disc having a relatively large thickness and mounted on the other shaft between the discs of small thickness. The two shafts are spaced from each other and the discs having small and large thicknesses have diameters such that the peripheral portions of the discs overlap one upon the other to form intersections therebetween on the rear and front sides. The yarn to be twisted is threaded through an intersection on the rear side, about the periphery of the intermediate disc and then through an intersection on the front side.

Abstract: An arrangement for timing the initiation of a spinning-in operation of an open-end textile machine is described. A sequencer is coupled to the take-up bobbin to provide an indication proportional to the increase in diameter of the yarn package during the take-up operation. The sequencer converts changes in such indication to a variable delay of signals to be applied to at least the take-up rollers and yarn-distributing rollers of the machine. The thus-delayed signals, whose delay is continually updated as the diameter of the yarn package increases, are applied to the appropriate rollers upon the detection of yarn breakage or other suitable initiation signal for the spinning-in mode.
