Abstract: A tap connector for use with a range of conductor diameters having a yoke comprising a pair of opposed plates extending angularly from a pad. A flat spring is attached to the terminal ends of each of the plates and extends towards the pad and is spaced from the inner face of the plates a predetermined distance. The springs terminate in an arcuate configuration so as to accommodate the conductor under a predetermined constant pressure. The pad is connected to a ground cable. High amperages caused by lightning or short circuits create an electromechanical force which drives the terminal ends of the springs toward each other so as to provide higher mechanical pressure about the conductor under such fault conditions.

Abstract: Friction welding apparatus for joining a rotatable element to a fixed element by means of a continuous drive system including apparatus for precisely orienting the rotational position of the rotatable element relative to the fixed element. Control apparatus is provided terminating the applied rotational force after a predetermined number of rotations and allowing the rotatable element to enter a coast down welding stage for a predetermined period of time, after which time the coast down rotation is stopped and a final forge pressure is applied whereby the rotational position of the rotatable element is precisely located relative to the fixed element when weldment is complete.

Abstract: A protective cover is provided for a standard rectangular transformer connector bar and for pedestal bar connector having ports for cable installation and threaded boreholes in adjacent ninety degree planes. The cover comprises a translucent housing open at one end and closed at the other when used with the transformer bar connector, and closed at both ends when used as a pedestal bar connector. The cover has a plurality of internal aligning ribs having apertures therein which allow longitudinal passage of the connector bar therethrough. A plurality of parallel access ports through the housing extend longitudinally and are spaced from each other ninety degrees so as to be alignable with the installation ports and boreholes of the bar connector. Opposed flexible tines extend across each of the access ports from the edges thereof.

Opposed flexible tines extend across each of the access ports from the edges thereof. The apertures in the ribs are geometrically configured so as to align the access ports with the installation ports and boreholes of the connector bar for either a right-hand or left-hand installation of the connector bar on the transformer stud.

Abstract: A bar connector is provided whereby, when the connector is in a locked position on a transformer bushing, a set screw is provided having a conical tapered end. An internally threaded bore hole is selectively provided in the connector at a point such that, when the connector is secured on the transformer bushing, the tapered conical end of the set screw bears against the chamfer of the threaded stud of the transformer, thereby locking the connector in place without damaging the threads of the stud. By utilizing this method for locking the transformer stud, thus eliminating the present lock nut, a completely insulated and sealed transformer bus is gained. An insulating cover positioned at the threaded end of the bar connector provides a flexible cylindrical base which, under thread pressure, seals the juncture of the transformer bushing with the insulated end of the bar connector. After threading the bar connector over the transformer stud, the stud is locked in place, as previously described.
