  • Patent number: 8025250
    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.
    Type: Grant

  • Patent number: 4983323
    Abstract: A composition for use in formulating detergents containing water, a neutral salt thixotrope and a water-soluble salt of an ether sulfate having the formula[R-A.sub.n O-SO.sub.3 ].sub.x Mwherein R is a hydrocarbon group containing from about 4 to about 30 carbon atoms, A is an oxyalkylene group selected from the group consisting of oxyethylene, oxypropylene, oxybutylene, oxytetramethylene and heteric and block mixtures thereof, n is an integer from 1 to 8 and M is a cation of a water-soluble salt, and wherein at least about 85% by weight of said ether sulfate has a number average oxyalkylene number of p-2 to p+3, wherein p represents the number of oxyalkylene groups of the most prevalent oxyalkylate species, and x is 1 or 2 depending on the valence of M.
