  • Patent number: 10315000
    Abstract: A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect each other creating a braid, a longitudinal axis that runs along the lumen and the filaments intersect the longitudinal axis at a braid angle. The braid angle can be varied by compressing or expanding the matrix along the direction of the longitudinal axis. A polymer coating is applied to the matrix such that the matrix is substantially impermeable to air. The hose has two states: (1) a relaxed state where the hose does not experience a force in the direction of the longitudinal axis; and (2) a stressed state where the hose experiences a force in the direction of the longitudinal axis. The braid angle is larger in the relaxed state as compared to the stressed state. A method of manufacture for the hose is also disclosed.

  • Publication number: 20130269818
    Abstract: A conduit for conveying a flowable material. The conduit has an elongate body made from a non-metallic material. The body has a lengthwise central axis, spaced ends, an inside surface bounding a passageway for communication of a flowable material between the elongate body ends, and an outside. At least one grounding component is embedded in the body to dissipate static electricity generated by conveyance of flowable material through the passageway.

  • Patent number: 8479775
    Abstract: Push-on hose construction for a self-gripping connection with a barbed nipple or other push in fitting end. The hose has an innermost core tube which exhibits a reduced coefficient of friction for easier insertion of the fitting end. Such core tube may be extruded or otherwise formed of thermoplastic polyurethane or other resin which is dulled or otherwise incompatibilized by the addition of an immiscible such as nonpolar polyolefin homopolymer, copolymer, or mixture thereof.

  • Patent number: 8430132
    Abstract: A preconditioned air hose includes an abrasion-resistant external layer made of robust nylon, an insulating layer, and an inner layer. The robust external layer protects the air hose from wear and degradation due to abrasion. The external layer may be made of a fabric with an abrasion resistance of at least 22,000 cycles to failure as measured using the ASTM D 3884 standard. This external layer fabric may be composed of filaments having a linear density of about 1,000 denier. The external layer fabric may weigh about 10.8 ounces per square yard.

  • Publication number: 20120090720
    Abstract: The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology.
