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: An electrical shielding jacket has a first shield formed from a wire mesh strip and a second shield formed from a flexible film bearing a metal coating. The jacket has a flexible casing which is closable by means of a zipper.

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.

Abstract: An electrical shielding jacket has a shield formed from a wire mesh strip. The cut ends of the strip are folded back onto the strip body and resistance welded in place. The jacket has a flexible casing which is closable by means of a zipper. A strip of hook and loop fastener is secured around the end of the jacket casing and is engagable to reinforce the zipper.

Abstract: This protective jacket of electrical conductors, tubing or the like has a semi-rigid generally tubular sheet body with male and female seam locking members along opposite lateral edges. A single barb-like hook on the male member engages a complementary pocket in the female member for securely interconnecting the edges and closing the seam. The jacket and seam closing members are integrally extruded and have sufficient stiffness that when the seam is closed, the jacket is in hoop tension.

Abstract: An improved heat insulating jacket slit lengthwise thereof held closed by a unique pair of dissimilar separable snap-lock seam members formed of extruded plastic and designed for heat-fused assembly to the inner plastic layer of flexible laminated sheeting having an outer layer nonfusible to said seam members. Each seam member includes a narrow groove sized to snugly seat and conceal the adjacent lateral edge of the sheeting. Each seam member includes internesting snap-lock members positioned to interlock when laminated sheeting fused thereto is wrapped about ducting. A blanket of resilient heat insulating material is laminated to the inner plastic layer of the sheeting and aids in holding the seam members interlocked.

Abstract: An electrically conductive removable jacket is provided for wire bundles or the like. The jacket comprises a flattened knitted metal wire tube with a strip of hook and loop fastener stitched along each longitudinal edge so that a tubular jacket is formed by overlapping the edges and securing the fasteners. Plural strips of hook and loop fastener assure that the jacket can be kept electrically "closed" regardless of the size of bundle encompassed. A resilient gasket is provided along one edge of the conductive jacket for making electrical contact with the opposite edge. The conductive jacket may be secured along one edge to one edge of a flexible electrically insulating jacket having fastening means along each edge for forming a tubular insulating jacket. The insulating jacket is inside of the conductive jacket.
