Abstract:
There is disclosed a conductive ball bearing assembly having an outer and inner race and operative to rotate with respect to one another about a common axis to allow an input wire electrically conducted to the outer race to rotate with respect to an output wire electrically conducted to the inner race. The improvement therewith consists of apparatus which eliminates electrical noise due to rotation which apparatus includes an electrically conductive C-shaped member or ring adapted to be clamped over said outer race and including depending spring assembies secured to said ring for resiliently contacting the inner race during rotation of said assembly. The spring assembly may consist of coiled springs or an arcuate spring member which are conductive and which depend from the C-shaped member to contact the periphery of the inner race at right and left sides to therefore shunt the electrical contact made by the conductive bearings between the inner and outer race and to therefore eliminate noise associated with such conductive bearing assemblies.
Apparatus For Preventing The Twisting Of Electrical Cables

439 17
Abstract:
An apparatus for preventing the twisting of electrical cables is constructed with bearing assemblies for conducting electrical current from a fixed cable end to a rotatable cable end. The apparatus employs a housing and fixed and rotatable cable clamping devices attached thereto. The housing and clamping devices cooperate to transmit tensile loads on the cable through the rigid apparatus housing thereby preventing wear and damage to the moving electrical contacts. An idler bearing is employed to minimize torsional strains on the cable conductors by permitting cable to rapidly change position within the apparatus.
