  • Patent number: 6051291
    Abstract: A heat protective sleeve for the protection of elongated members is disclosed, the sleeve having a first sheet of insulative material with an outer reflective layer. Oppositely disposed edges of the first sheet have means for joining the edges to a portion of the first sheet in overlapping relationship to form a tubular sleeve. A second insulative sheet is attached to the outer surface of the first sheet inward from the edges. The second sheet also has a reflective layer on its outer surface and is attached to the first sheet along its edges, parallel to the edges of the first sheet, thus, forming an air pocket between the sheets. A stiff monofilament wire bent into a spiral or other shape is disposed within the air pocket to maintain the pocket shape. In use, the air pocket is positioned facing a heat source and the sleeve interposes a reflective layer, an insulating layer, an air pocket, a second reflective layer and a second insulating layer between the elongated members and the heat source.

  • Patent number: 6048623
    Abstract: The present invention comprises methods of contact printing of patterned, self-assembling monolayers of alkanethiolates, carboxylic acids, hydroxamic acids, and phosphonic acids on metallized thermoplastic films, the compositions produced thereby, and the use of these compositions. Patterned self-assembling monolayers allow for the controlled placement of fluids thereon which contain a chemically reactive, indicator functionality. The optical sensing devices produced thereby when the film is exposed to an analyte and light, can produce optical diffraction patterns which differ depending on the reaction of the self-assembling monolayer with the analyte of interest. The light can be in the visible spectrum, and be either reflected from the film, or transmitted through it, and the analyte can be any compound reacting with the fluid on the self-assembling monolayer. The present invention also provides a flexible support for a self-assembling monolayer on gold or another suitable metal.
