Abstract: A relatively thin broad-area dielectric interfacing composed of dual filled layers of compliant silicone rubber in sandwiching relation to a porous glass-cloth carrier, one of the layers being pre-vulcanized and the other being subsequently cured and bonded in place once the composite interfacing has been applied to heat-sink surfaces adapted for abutment with the device for the intended heat transfer. The soft rubber interfacing offers good dielectric and insulating and voltage-breakdown characteristics even when well loaded with thermally-conductive oxides, and intimate voidless surface contacts and high-quality thermal matching are fostered both along abutting compliant surfaces of the pre-cured portion of the interfacing and along fully bonded surfaces of the portion cured in situ.

Additionally, the tubular projections are provided with radially extending retention burrs for mechanically holding the mounting pad in place on a substrate pending actual mounting of a semiconductor device thereon.

Abstract: Animal tissue and the like having silver sulfadiazine incorporated therein is useful as a covering for burns and/or wounds. The silver sulfadiazine is incorporated in the tissue by soaking the tissue in an ammoniacal silver sulfadiazine solution or suspension. When the silver sulfadiazine is so incorporated in the tissue via an ammonium solution, more silver is found to be present than would normally be expected and the effectiveness of the thus treated tissue as a wound covering increases.
