Abstract
911,877. Couplings between relatively movable conducting parts. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 30, 1961 [July 5, 1960], No. 23729/61. Class 38 (1). A rotary contact arm for high frequency high intensity currents comprises a part 1 which has means for fixing to a shaft 3 and a part 5 coaxially arranged and slidable with respect to the part 1, the parts being forced apart by means of a spring 19, so that a contact 7 on the part 5 engages a conductor 9 which may be a helical coil. The movable part 5 has contact fingers 25 engaging the part 1 and cooling fins 29 which are such that their radial length is considerably shorter at at least one point on their circumference to provide a short current path at this point. The surfaces of parts 15 and 21 preferably have a layer of silver to carry the currents, this layer having a protective covering of gold and the contact 7 is preferably of graphited silver. A metal bellows for contact between parts 1 and 5 is also mentioned.
