Abstract: A closeable heat-shielding jacket is formed from a substantially impervious flexible sheet of polyurethane-coated woven glass fiber textile. The textile has a substantially continuous layer of polyester coated with a reflective layer of 10 aluminum adhered onto one face. A strip of acrylic pressure-sensitive adhesive is adhered along one edge of the aluminum layer for use in closing the heat-shielding jacket. The adhesive is selected to be resistant to continuous exposure to at least 120° C. The adhesive also has a thickness of at least 0.1 mm and is soft enough to conform to the textured surfaces of the heat-shielding material. The heat-shielding jacket material has a removable release layer over the strip of pressure-sensitive adhesive. This jacket material is wrapped around a wire bundle or the like, and the outside edge is overlapped over the inside edge, which has the strip of adhesive, the width of the adhesive strip to close the jacket with the shiny side out.

Abstract: A side opening heat shrinkable cable jacket having a tube of heat shrinkable plastic with a longitudinal slit. A stripe of pressure sensitive adhesive borders one edge of the slit on the outside of the tube. The adhesive has sufficient internal cohesion and adhesion to the plastic of the tube to shrink with the tube when heated to the shrinking temperature of the plastic. A release layer covers the stripe of pressure sensitive adhesive. The cable jacket can also have a longitudinally extending strip of electrically conductive fabric bonded to the inside of the tube along an edge of the slit. The conductive fabric strip has a width greater than the inside diameter of the cable jacket when the tube is heat shrunk.

Abstract: An electrical shielding chamber has six electrically conductive rigid walls in electrical contact with each other. A first wall forms a first door and a second wall forms a second door, each of which is selectively attachable to at least three other walls. The chamber is collapsible for forming a substantially flat package, and expandable for forming a substantially electrically-shielded compartment.

Abstract: A tubular electrical shielding sheath has inner and outer flexible electrically insulating sheets and an electrically conductive sheet shield sandwiched therebetween. An edge of the conductive shield is folded over the adjacent edge of the inner sheet and brought into electrical contact with the other edge of the shield. One edge of the outer sheet overlaps the other edge of the outer sheet and is adhesively bonded thereto, and one edge of the inner sheet overlaps the other edge of the inner sheet and is adhesively bonded thereto.
