  • Patent number: 10899427
    Abstract: A heated floor panel assembly with an impact layer is made to absorb blunt force and protect a heating element inside the assembly. The assembly further includes a plurality of structural layer made of a reinforced polymer matrix, one or more core layer with a honeycomb or foam structure for absorbing shear stress, and a heating layer containing the heating element. The impact layer is a composite layer with a resin impregnated fiber matrix.

  • Patent number: 8844975
    Abstract: A hose intervention clamp is provided for clamping a hose/connection nipple assembly, wherein the hose/connection nipple assembly has a hose and a connection nipple having a locking slot. The hose intervention clamp includes a locking ring, an upper clamp portion, and a lower clamp portion pivotally connected to the upper clamp portion. The upper and lower clamp portions are pivotally moveable relative to each other from a first at least partially open position to a second locking position, and in the second locking position the upper and lower clamp portions define a recess for receiving the hose/nipple assembly. The locking ring is configured to be received in the locking slot when the upper and lower clamp portions are in the second locking position. A hose intervention clamp system includes a hose/connection nipple assembly having a hose and a connection nipple having a locking slot, and the described clamp.

  • Patent number: 7490870
    Abstract: A hydraulic flange connection having a formed tube in physical conjointness with a contoured sleeve member, the conjointness including the sleeve member having a cylindrical body bore, a cylindrical outer portion tapering at one axial end into a frustoconical portion abutting one bore end, the cylindrical outer portion also merging into an annular outer end surface having inner and outer edges defining a bowl-shaped recess with a raised annular inner end surface; the tube having a cylindrical portion extending into and through the sleeve member bore, a radial flange portion thereof including an axially outwardly-directed, openly curved, circumferential radial groove, with an inner surface of the flange portion conforming axially and radially with an abutting complementary surface of the bowl-shaped outer recess portion in a fully nesting retention relationship. Details of achieving the conjointness between the tube and the sleeve member are also set forth in product-by-process claim recitation.
