  • Patent number: 10378210
    Abstract: Methods and devices for sealing and/or gripping concrete strengthening tendons. Some embodiments provide a method of forming a seal between an encapsulated anchor and a sheath of a tendon engaging the encapsulated anchor. Other embodiments provide a splice for forming a seal around a discontinuity in the sheath of a concrete tensioning tendon. Some embodiments provide a seal assembly for forming a seal between a tubular extension and a sheath of a tendon to protect an exposed portion of the tendon contained within the tubular extension. Some embodiments also provide a method of forming a fluid tight seal between tubular extension and a sheath of a tendon, while other embodiments provide a method of gripping the sheath of a tendon with a tubular extension to prevent the sheath from moving relative to the extension.

  • Patent number: 9169898
    Abstract: A method is disclosed for attaching a ferrule to a dragline rope. The method comprises locating the dragline rope in a die of a die-press, locating over the dragline rope a ferrule that is lined internally with a deformable material, and forcing the ferrule longitudinally through the die. The ferrule is caused to be internally expanded and be extruded back over the dragline rope, causing the lining to deform directly against the dragline rope and fastening the ferrule to the dragline rope.

  • Patent number: 8764420
    Abstract: An eccentric-screw pump has an axially split stator having axially opposite intake and output ends and an elastomeric liner defining an axially throughgoing passage. Respective intake and output housings are releasably secured to the intake and output ends of the stator. An axially extending screw rotor in the passage has an end in the intake housing. A drive includes a rotatable universal joint having a pair of relatively swivelable parts in the intake housing. Respective generally complementary formations on the end of the rotor and on one of the universal-joint parts can fit axially together to rotationally couple the one universal-joint part with the rotor. A latch secures the formations axially together for angular force transmission between the one universal-joint part and the rotor.

  • Patent number: 6718707
    Abstract: An assembly for compressing a foundation piling prevents individual piling segments from sliding out of alignment. The assembly is an anchoring device that is lowered into a passageway running through a concrete or steel foundation piling to a desired depth. The anchoring device is suspended to a cable and has a center section and at least one moveable wing or wedge attached to the center section. Then a weight is dropped onto the anchoring device. The force of the impact causes the wings on the anchoring device to slide down and extend away from the center section. The force of the impact also forces the wings to grip the piling because the anchoring assembly is wider than the passageway when the wings slide down the center section. Tension is applied to the cable, which is now secured to the piling by the anchoring device. The tension in the cable creates a compressive state on the piling which prevents the individual segments from sliding out of alignment.

  • Patent number: 6634830
    Abstract: A foundation repair piling made up of segments is post tensioned by a cable fed into the segments after the piling is installed. A cable anchor serves as a base segment of multiple concrete piling segments. After installing all the concrete segments on top of the base segment, a cable is inserted into passages in the segments. The cable is threaded through the completely installed piling segments and into the cable anchor. After the cable bottoms out in the cable anchor, upward tension is applied to the cable. As the cable is pulled, cable lock members in the cable anchor increase gripping pressure even as the cable tension increases, thereby solidly anchoring the end of the cable in the cable anchor. After the desired tension is reached, the cable is terminated at the top of the last segment. The tension is held by a termination lug at the top end of the cable.

  • Patent number: 6604886
    Abstract: In a preferred embodiment, a light weight telescope assembly for bicycles that is readily adjustable by riders in the field and that provides smooth action of the suspension system. This telescope assembly contains roller bearings to reduce stiction and prevent torsional losses. The adjustment mechanism includes an adjustable outer race shim composed of two oppositely tapered races moving longitudinally in relation to each other, thereby causing their combined thickness to expand or contract thus allowing the bearing pre-load to be adjustable. Integral with this adjustable pre-load mechanism is a bayonet-style collar whose design enables bearing pre-load adjustment from a position that is readily accessible by consumers. In addition, this collar enables greater geometric latitude on the shape of the inner tube, thereby enabling significant strengthening of the telescoping assembly using light weight materials and lower cost manufacturing processes that hitherto have been unachievable.

  • Patent number: 6547480
    Abstract: An object of the present invention is to obtain economically a corrosion-resistant, abrasion-resistant or heat-resistant composite structure having a high strength by joining together two members so that the two members may not separate from each other. A composite structure is formed by combining and joining together first and second members. The first member has a protruding part expanding toward its extremity and the second member has a concave part defining a space of a shape corresponding to that of the protruding part of the first member and capable of forming a predetermined clearance between the protruding part of the first member and a surface of the concave part of the second member when the first and the second member are combined. Separation of the first and the second member from each other is prevented by inserting wedges in the clearance. Vacant portions of the clearance remaining after the wedges have been inserted in the clearance may be filled up with a filler.

  • Patent number: 6464424
    Abstract: A method of repairing a crack in a boiling water reactor shroud includes forming a pair of slots in the shroud on opposite sides of the crack in angled relation to one another so that the lateral spacing between the slots increases in a direction parallel to the crack, lowering a wedge clamp with laterally spaced slides into the annular space between the core shroud and the reactor vessel, positioning the slides in the slots, and moving the clamp in the direction of increasing lateral spacing between the slots to an operational position where the clamp prevents unacceptable opening of the crack during reactor operation by providing a structural load path which transmits structural loads across the crack. The slots are preferably configured to mate cooperatively in a manner which prevents the clamp from moving in a radially outward direction relative to the shroud once the clamp has been installed.
