Technologies are described for restraining systems. The systems may comprise a base, a stationary arm, a swing arm, a rod, first straps, and second straps. A bottom end of the stationary arm may be attached to a first end of the base. A bottom end of the swing arm may be attached at a second end of the base. The rod may be attached to top ends of the stationary arm and the swing arm. First straps may be attached to the stationary arm and configured to loop around and support an object. Second straps may be attached to the swing arm and configured to loop around and support the object. The rod may move and push the top of the swing arm away from the top of the stationary arm. A friction force between the first and second straps and the object may be effective to restrain the object.

Piloted electromagnetic brake for controlling the tension of the weft threads in weaving machines, in particular of a weft thread which has a high number of knots, of the type including a pair of opposite elastic thin plates between which the weft thread runs, an operated thin plate being adjusted in position by an electromagnetically controlled operating piston, and a resisting thin plate being resistant against an elastic contrast unit, in order to control the intensity of the contrast force between the pair of thin plates. The resisting thin plate and the operated thin plate have fulcrum points in correspondence of a central portion thereof, so as to be able to freely oscillate in a plane containing the weft thread, during the passage of a knot between them, and the fulcrum points are offset by a set length along the weft thread running direction.

A wire feeder includes a tensioner with a discrete number of compressive force settings for applying a desired compressive force to welding wire fed through the wire feeder is provided. The tensioner includes an adjustment knob with a discrete number of detents disposed along a helical surface adjacent an inner bore of the adjustment knob. The tensioner also includes a pin extending from an end of a tensioning post located in the inner bore, the pin being configured to align with the detents of the adjustment knob. Rotation of the adjustment knob adjusts alignment of the pin among the discrete number of detents, which correspond to the discrete number of compressive force settings.

A yarn tensioner is designed for adjusting tension in a running yarn. The yarn tensioner includes a rotatable tension wheel having opposing yarn-contacting surfaces formed along an annular region thereof and configured to frictionally contact opposite sides of the running yarn such that the running yarn causes rotational movement of the tension wheel. An elongated wheel shaft is directly affixed to the tension wheel. A tension adjustment assembly frictionally contacts the wheel shaft, and creates select rotation resistance between adjacent parts of the assembly and the wheel shaft such that rotation of the tension wheel is adjustably frictionally controlled, thereby adjusting tension in the running yarn.

An electric wire accommodation device includes an accommodation device body, an electric wire reel being a reel around which an electric wire is wound and configured to be accommodated inside the accommodation device body, in which the electric wire is configured to be pulled out to outside of the accommodation device body and to be intermittently reeled out by a reel-out mechanism provided outside the accommodation device body, and an electric wire gripping member attached on a pull-out route in the accommodation device body along which the electric wire is pulled out and configured to grip the electric wire with a gripping force smaller than a reel-out force applied by the reel-out mechanism.

In accordance with one aspect of the present disclosure, an instrument for tensioning a surgical cable is provided that includes a rotary tensioner that is rotatable in a tensioning rotary direction to apply tension to the surgical cable. The instrument further includes a body supporting the rotary tensioner, a pawl portion of the body configured to be received at least partially in a recess of a ratchet gear of the rotary tensioner, and a living hinge portion of the body supporting the pawl portion. The living hinge portion is configured to permit the pawl portion to be shifted out of the recess and shifted into an adjacent recess of the ratchet gear with turning of the rotary tensioner in the tensioning rotary direction

A container may be provided. The container may comprise a first surface and a second surface concentric with the first surface. The first surface and the second surface may define a volume. The volume may house a concentric length of multiple parallel conductors. The multiple parallel conductors may pass through a restricting mechanism to restrict the multiple parallel conductors to pass at the same rate and at the same length.

A self-synchronizing yarn tension control system is provided. Self-synchronizing yarn tension control includes a yarn tension sensor, a yarn brake, and a controller configured to control the system. The controller includes one or more processors and one or more memory devices. The memory devices configured to store the more memory devices configured to store one or more tension pulses, store one or more tension thresholds, and store instructions that when executed by the processors cause the processors to perform operations. The operations include obtaining a first yarn tension value and selectively operating the yarn brake based on the tension pulses. Obtaining a second yarn tension value by operating the yarn brake based on the tension pulses. Determining whether the first tension value exceeds the second tension value. Obtaining a yarn tension signal from the yarn tension sensor, comparing the yarn tension signal to the one or more tension thresholds, generating one or more brake control signals based on said comparison and operating the yarn brake based upon each of the one or more brake signals.

A self-synchronizing yarn tension control system is provided. Self-synchronizing yarn tension control includes a yarn brake, a yarn movement sensor, a yarn tension sensor, a yarn brake, and a controller configured to control the system. The controller is configured to store one or more tension thresholds and store instructions that when executed cause one or more processors to perform operations. The operations include obtaining a yarn movement signal from the yarn movement sensor, determining whether a textile machine is operational based, at least in part on the yarn movement signal, obtaining a yarn tension signal from the yarn tension sensor, comparing the yarn tension signal to the one or more tension thresholds, generating one or more brake control signals based on said comparison, and operating the yarn brake based upon each of the one or more brake signals.
