  • Patent number: 5024251
    Abstract: A oiltight lay-in wireway comprised of wireway sections with hinged covers and a joint connector between the covers of two adjacent wireway sections. The covers overlay the joint connector. The joint connector has a free floating hinge connecting it to the wireway sections, allowing the cover to provide the main compression force on the joint connector gasket. A bolt with a splined shoulder provides a grounded connection between adjacent wireway sections while still allowing the joint connector to float freely. The compression force on the joint connector is exerted by the covers which are held closed by clips on the wireway sections. An oil resilient gasket provides a seal between adjacent wireway sections, between the joint connector and wireway sections, between the cover and joint connector, and between the cover and wireway sections. Raised ends on the cover contact the joint connectors while still maintaining a seal with the wireway sections.

    Abstract: Disclosed is a closure member for insulating, sealing, waterproofing and otherwise protecting an object from the elements. The closure member is of integral, one-piece construction, is of heat-shrinkable material, has a main body for enveloping the object and easily hand-assembled hooks, formed from material-sandwiched, angled and articulated inserts, interfoldable to define a joint and form thereby an enveloping tubular member. The hooks have on their ends small projections defining detents that are mechanically imbeddable for positive joint closure and seal, while affording a wide range of alignment in the interfolded and sandwiched assembly of the hook.

  • Patent number: 4396039
    Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm.sup.2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm.sup.2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. The adhesive layer is smoke-permeable and is preferably composed of a material system which sets without a chemical reaction.

  • Patent number: 4391303
    Abstract: An article for forming a tubular protective cover around telephone and electrical cables comprising a generally flat band of material having opposite upper and lower surfaces and end edges, one of the surfaces being planar, the other surface being provided with a plurality of spaced grooves therein. Each groove is of V-shape and has inclined sides which intersect to form an apex proximate the planar surface to form a hinge where the band can be folded to enable the band to surround a cable. The other surface of the band is relatively flat between the grooves to define a continuous planar surface. At the grooves, the band is formed with elevations projecting beyond the plane of the surface in continuation of the sides of the grooves such that with the band folded at the hinges, the elevations at the sides of the grooves approach one another to provide a stiffening effect for the folded band around the cable.

  • Patent number: 4384906
    Abstract: A method for holding together the opposing ends of a flat sheet wrapped around an elongate substrate employs one or more closure devices, each closure device comprising a pair of frictional elements and a means for interengaging same. The frictional elements each have a channel member having a slit and a rod member positionable within said channel member, which when so positioned cooperates therewith to provide a conduit thereinbetween and to apply frictional forces to one end of the flat sheet when the end has been inserted through the slit and is in position between the rod member and the channel member. The closure is especially suited for joining elastomeric flat sheet, the sheet and closure device or devices collectively providing a protective closure.

  • Patent number: 4379473
    Abstract: A longitudinally divided cable sleeve which is composed of a shrinkable sleeve member of a shrinkable material having a bead on each edge for engagement with a sealing bar to form a sealing system characterized by each of the beads having a non-shrinkable longitudinally extending strengthening element embedded therein and the sealing bar having a pair of side elements interconnected by a central web, said side elements projecting from the central web to form an undercut groove on each side of said web so that the sealing bar is a cross-sectional configuration of a pair of C-shaped profiles facing in opposite directions and each groove receives one bead of the sleeve member to close said cable sleeve. The sealing bar is preferably made of a material having a good heat conduction property to improve the heating of the inner sealing zones during a shrinking process. If desired, a coating of a fusible adhesive can be applied in the area of the sealing zones to increase the sealing effect.

  • Patent number: 4307756
    Abstract: A spacer is coiled about a drawn, seamless copper tube, and a metal foil or metallized paper ribbon is folded around the coiled spacer. A blend for foaming is injected into the unoccupied space between the folded foil or ribbon and the inner tube, to generate a cyanurate-modified polyurethane foam network in which phosphorous or halogen molecules are embedded by chemical bond. A flame-resistant ribbon is folded about the metal tube. The resulting product and further details of the process are described.

  • Patent number: 4296157
    Abstract: An elongated cylinder is essentially comprised of a continuous side wall with a narrow weak wall segment along the length thereof for fracturing by the application of a small force to permit access to the interior of the cylinder along the fractured side wall. The weak side wall segment is in the form of a very thin web section produced by grinding or in a molding operation which may additionally include the filling of the hollowed area of the side wall with a dissimilar material. The article is used for cable placement, varmint protectors for tree trunks, protectors for wire harnesses, protectors for cable splices, and a mold for concrete.

  • Patent number: 4276909
    Abstract: A heat-recoverable wrap-around device is made from heat-shrinkable sheet material, two opposed edges of which may be secured together by fasteners so as to form a sleeve prior to recovery. Each edge region is provided with a strip of rigid material lying generally in the plane of the sheet. The strips may be bonded or embedded within the sheet material, or positioned in terminal loops therein, and are preferably so designed that they can be deformed into an interlocking relationship which withstands the recovery forces.

  • Patent number: 4275707
    Abstract: This invention relates to a ventilating system of the type comprising a duct for distributing heated or cooled air with distribution pipes attached to the duct. Each pipe is attached by means of a collar which has one side connected to the duct and the opposite side providing means for holding a pipe end. The collar includes integrally formed lock means which permit formation of the collar from a strip and joining of the strip ends to provide the desired collar configuration. The lock means include a projection on one end of the collar strip, the projection defining an outer edge and angularly, inwardly extending side edges. This projection is receivable within a notch defined by the other end of the collar strip. The notch includes an inner edge and angularly and inwardly directed side edges with collar portions formed on opposite sides of the notch. The projection can be quickly inserted in the notch, and a secure relationship is achieved.
