Abstract: Sheet material useful for making bonded electrical connections, especially to sets of small side-by-side terminal pads. In one typical form, the sheet material is an elongated tape comprising an elongated flexible insulating backing; a plurality of narrow spaced parallel elongated electrically conductive stripes on the backing; and electrically conductive adhesive disposed over the stripes comprising a layer of adhesive material in which are dispersed a monolayer of electrically conductive elements which have an average thickness greater than the average thickness of the adhesive layer, and the top edges of which are higher than at least part of the exterior surface of the adhesive layer surrounding the element.

Abstract: Adhesive tape useful in supporting an array of parallel optical fibers in an optical transmission cable comprising an adhesive-covered biaxially oriented polyethylene terephthalate film having defined ranges for the proportion of gauche and trans conformations of the ethylene glycol linkages of the polyethylene terephthalate molecule, as measured by infrared spectroscopy, whereby extreme dimensional stability is achieved.

Abstract: Free flowing resin powder which upon striking a heated article fuses, flows and hardens to provide a protective coating, which powder consists of a mixture of rough and rounded particles, the rough particles having a granular appearance as a result of being pulverized and the rounded particles having smooth, glossy, spheroidized surfaces as a result of being briefly heated to a temperature above the softening point. Preferably each particle of the powder is a blend of thermosetting resin and curing agent.

Abstract: Improved electrostatic coating is obtained by heat-rounding or spheroidizing pulverized resin particles so that 30-80% take on a glossy appearance while the rest remain rough to provide a mixture that is free flowing at ordinary room temperature and would pass through a screen having openings not exceeding 200 micrometers. Preferably each particle of the mixture is a blend of thermosetting resin and curing agent.
