A tension apparatus having a mechanical section, storage unit, output torque calculation section, and exciting current calculation section is disclosed. The mechanical section has an electromagnetic brake driven by an exciting current to generate an output torque and applies a tension to a material in continuous form, which is being wound and stretched, in accordance with the output torque of the electromagnetic brake. The storage unit stores actually measured characteristics between an exciting...

In one embodiment, a device includes: first, second, and third paired-strand levers each configured to receive a pair of tensile strands at locations spaced apart from one another along the paired-strand lever; first, second, and third fulcrums each supporting a corresponding one of the paired-strand levers between the tensile strand receiving locations; a fourth lever linked to the first and second paired-strand levers through the first and second fulcrums, respectively, at secondary lever link...

A tension member comprising a plurality of fiber filaments gathered into a plurality of strands. The filaments run close together, and a protective sheath is provided around the strands. Each strand is coated on the exterior thereof with a strand sheath of a material having a low friction coefficient, permitting the strands to move longitudinally in relation to one another and independently of each other.

A tension apparatus includes a mechanical section, signal output section, smoothing circuit, maximum value holding circuit, constant current driving circuit, and discharge circuit. The mechanical section has an electromagnetic brake driven by an exciting current to generate an output torque and applies a tension to a material in continuous form which is being wounded and stretched by the output torque of the electromagnetic brake. The signal output section repeatedly outputs a PWM (Pulse Width M...

A tension member, for use as a tendon or tether for a tension leg platform consisting of a plurality of carbon fiber filaments (6) gathered into a plurality of strands (5) in which the filaments (6) run against one another, around which strands there is arranged a sheath (16). The tension member comprises pressure-resisting spacers (7) having recesses (9, 11, 12, 14; 25, 26, 28, 31) wherein the strands (5) are laid singly so that they can move in the longitudinal direction unobstructed by each o...

A spring-driven reeling mechanism for safety belts 17 in motor vehicles has a belt reel 11 which is rotationally fixedly connected to a first draw reel 12 with a spiral-shaped guide groove 15. A flexible draw member 13 is wound into the guide groove 15 and extends to a second draw reel 14 with a spiral-shaped guide groove 18. The two draw reels 12, 14 taper in opposite axial directions. The draw reel 14 is acted on by a spiral spring 16 in a direction of rotation such that the safety belt 17 is ...

A tensioning tool which holds the free ends of a tension band secured to a clip and clip screw and rotation of an adjusting knob causes tension to be applied to pull the band through the clip until the desired tension is achieved.

The present invention provides an implosion prevention tension band 16 for use in a cathode ray tube (CRT) 10. The CRT includes a faceplate panel 18 with a substantially flat viewing faceplate 21 and a peripheral rearwardly extending sidewall 22 having an inside blend radius 23 from the viewing faceplate 21 to the sidewall 22. The tension band 16 is a single layer band surrounding the panel 18 and having a predetermined width extending rearwardly from near the faceplate 21 to at least half the d...

A machine which applies tension to a strip of steel which has been passed through a slitter. The machine includes two sets of rollers which engage the slit material to maintain tension. The rollers are slidable in the machine frame to allow for rapid changing of the rollers to accommodate various types of slit material.

Apparatus to adjustably support a yarn tension control between a knitting machine and the yarn creel which is supplying yarn to the knitting machine.
