Abstract: A home security device comprising a first attachment device, mounted on a distal end of a first rigid arm, adapted to be removably secured to a door or window, a second attachment device, mounted on a distal end of a second rigid arm, adapted to be removably secured to a floor or wall adjacent to the door or window, proximal ends of the first and second rigid arms positioned end to end forming a substantially straight line, and a fastening device, releasably holding the proximal ends in position, adapted to remain secure against force exerted at the distal ends of the rigid arms and to release the proximal ends from position in response to force exerted near the proximal ends and substantially perpendicular to the axis of the rigid arms.
Abstract: An apparatus includes (a) a device which is capable of selectively generating heat in electrically-conductive material without substantially generating heat in non-electrically-conductive material, (b) a device capable of heating non-electrically-conductive material, and (c) an insulating shield between the two devices to help focus the energy generated by at least one of the devices.
Abstract: Hot-melt silicone pressure sensitive adhesive compositions containing alkylmethylsiloxane waxes, methods of using the compositions and devices made using the compositions are disclosed. The hot-melt silicone pressure sensitive adhesive compositions include a mixture of (i) a silicate resin, (ii) a silicone fluid, and (iii) an alkylmethylsiloxane wax having a melting point of between 30.degree. C. and 70.degree. C. The alkylmethylsiloxane wax decreases dynamic viscosity of the adhesive at temperatures ranging from about 50.degree. C. to about 200.degree. C.

Abstract: A method of making a hot-melt silicone pressure sensitive adhesive-coated substrate comprises (a) heating a hot-melt silicone pressure sensitive adhesive composition which includes a mixture of (i) a silicone resin, (ii) a silicone fluid, and (iii) from about 0.5 to about 10 weight percent, based on the total weight of the silicone resin and the silicone fluid, of a non-flammable hydrocarbon having a weight-average molecular weight of from about 300 to about 1500 as measured by gel permeation chromatography calibrated with narrow distribution polydimethylsiloxane standards (b) coating the heated adhesive composition onto a substrate, and (c) cooling the coated adhesive composition until it is in a generally non-flowing state.
Abstract: A surgical dressing comprising a sheet of silicone gel having a wound-facing surface and laminated to the other surface a film of silicone elastomer.The dressing is particularly adapted to the treatment of burns.
