  • Publication number: 20090242228
    Abstract: A plurality of individual elements are imparted with reverse axial twist and collectively twisted into a multi-element assembly. Each individual element has an axial twist direction in an opposite direction from the axial twist direction of the collective multi-element assembly. The reverse axial torsion in the assembly tightly binds the plurality elements in the assembly to resist separation.

  • Publication number: 20090242232
    Abstract: A theft deterrent cable may be provided. First, a plurality of unique codes may be created. Then a plurality of indicia may be placed periodically and longitudinally on the interior of the cable that may not be viable from the exterior of the cable. The plurality of indicia may respectively correspond to the plurality of unique codes. An indicator may be placed on the exterior of the cable. In a database, the plurality of unique codes may be assigned to an organizational entity. The organizational entity may comprise a first enterprise. Next, an indication that the cable is to be transferred from the first enterprise to a second enterprise may be received. In response to the received indication, the plurality of unique codes may be assigned in the database from the organizational entity comprising the first enterprise to the organizational entity comprising a second enterprise.

  • Publication number: 20090173818
    Abstract: Length equalization may be provided. First, a plurality of conductors may be paid off from a plurality of pay-off devices respectively corresponding to the plurality of conductors to form a cable. The plurality of conductors comprising the cable may then be wound onto a take-up device. During the winding process, a guide device may be rotated to cause the plurality of conductors to have substantially a same length after the cable has been wound onto the take-up device. The guide device may be disposed between the take-up device and the plurality of pay-off devices. The guide device may have holes respectively corresponding to each of the plurality of conductors. Each of the plurality of conductors may pass through a respective hole in the guide device.

  • Publication number: 20090107719
    Abstract: A cable assembly may be provided. The cable assembly may comprise a conductor core and a binding element. The binding elements may be configured helically around the conductor core. In addition, the binding element may be configured to, when the cable assembly is pushed through a conduit having at least one sweep, eliminate buckling of the cable assembly. Moreover, the binding element may be configured to cause a first pushing force on the cable assembly having a magnitude less than a second pushing force on the cable assembly corresponding to pushing the cable assembly through the conduit without the binding element on the conductor core.

  • Publication number: 20090071677
    Abstract: A vibration resistant cable may be provided. The vibration resistant cable may comprise a first conductor and a second conductor. The second conductor may be twisted around the first conductor at a lay length configured to cause a locking force between the first conductor and the second conductor. The locking force may be configured to prevent relative movement of the first conductor and the second conductor that may result in bags in the vibration resistant cable. The lay length may be predetermined or may vary a predetermined amount per unit of length of the vibration resistant cable. The lay length may be c1d+c2, where d may be the diameter of the first conductor and the second conductor and c1 and c2 may be constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable.
