  • Publication number: 20150136474
    Abstract: A connecting system for quickly securing a hollow tube to a structure or another hollow tube using a connector that has housing with a tapered interior edge that operably engages a tapered locking wedge received therein. When the tube is inserted into the tapered locking wedge, the locking wedge therein holds and locks the tube in place in the connector. A guide ring may be provided within the connector to facilitate proper alignment of the tube within the connector and provide excellent electrical conductivity throughout the entire tube connecting system. One or more roller bearings may be provided within the wedge to facilitate initial tube insertion and then compression locking of the tube by the wedge. The connector can include a variety of structure engaging portions to allow the connector to be operably secured to a variety of structures such as electrical junction boxes, electrical conduits, tubes, armored cables, metal clad cables, flexible metal cables and the like.

  • Patent number: 8920929
    Abstract: The present disclosure provides a flexible, halogen-free, flame retardant composition. The composition includes from about 25 wt % to about 95 wt % of a thermoplastic polyurethane (TPU); from about 5 wt % to about 50 wt % of an olefin block copolymer (OBC); and from about 30 wt % to about 70 wt % of a flame retardant. The flame retardant is selected from resorcinol bis(diphenyl 5 phosphate) (RDP), bis diphenyl phosphate (BDP), bisphenol-A bis(diphenyl phosphate) (BPADP), aluminum trihydrate (ATH), a nitrogen/phosphorus-based halogen-free flame retardant, epoxidized novolac resin, and combinations thereof. The composition requires no compatibilizer for the TPU and OBC. The composition finds application in wire and cable structures.

  • Patent number: 8863779
    Abstract: The present invention discloses an integrated supplying apparatus for gas and sizing. It comprises a sizing barrel, a gas supply unit and a switching unit. The sizing barrel and the gas supply unit are both connected with the switching unit. When the switching unit is fixed in a first state by a safety component, the gas supply unit can only output high pressure gas through the switching unit. When the switching unit is converted into a second state by releasing the safety component, the gas supply unit in turn outputs some high pressure air into the sizing barrel through the switching unit, so that the sizing inside the sizing barrel is output under the action of the gas pressure and the gas inside the sizing barrel is then output when completing the output of the sizing.
