Abstract: A connective improvement disposed on the exterior of a cathode ray tube includes the metallic fracture-protective member peripherally surrounding the panel as an integral part of the circuitry connecting the exterior coating on the funnel portion of the tube envelope with appropriate grounding circuitry in the chassis. A discrete deposition of connective conductive material is applied to the exterior of the funnel and panel areas, whereof the funnel disposed section has the exterior funnel coating overlaid thereon. The opposed panel-disposed section makes positive connection with the peripheral protective member, which in turn, has a connective element associated therewith to complete the grounding circuitry without disturbing the intervening conductive material or the funnel coating associated therewith.

Abstract: An electrical bussing and jumper assembly for use with electrical switching devices such as circuit breakers in a three-phase distribution system. The bussing and jumper assembly comprises a plurality (three) of relatively thin, wide, bus plates stacked together in a compact sandwich-like array. Each of the plates has a plurality of jumper portions extending transversely through openings or cutouts provided in the bus plates superimposed thereover.

Switching devices for use in a current distribution system are attached to the jumper portions of the bus plates, using threaded openings provided in the jumper portions.

Abstract: There is described an electroplating method and device for accomplishing the same whereby metal plating is disposed on a wire as said wire moves along an established path through the device.

The wire to be plated is established at a negative electrical potential and moved through said electrically conductive means. Accordingly, the conductive means is adapted for providing the electrolyte therein with a positive electrical potential to thereby provide the desired deposition.
