  • Patent number: 8437855
    Abstract: Connector assemblies for use with implantable medical devices having easy to assemble contacts are disclosed. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore fore receiving a medical lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together.

  • Patent number: 8267027
    Abstract: The invention is a sailboat rigging system and method for forming same. It is formed from a plurality of resin prepreg high strength fiber strands, tows or roving. The fiber are laid out in a preferred rigging configuration with the fiber strands, tows or roving being placed under generally equal tension. The resin in the prepreg fibers bonds the fiber strands, tows or roving to consolidate them together substantially without open spaces therebetween. If desired, the fiber strands, tows or roving can be branched out at branching points to provide for continuous rigging, and selective fibers can be dropped at various sections of the rigging for weight savings.

  • Patent number: 7137617
    Abstract: A composite tension member. The composite tension member is assembled from a number of composite rods, each having two ends. A wedge plug is formed around the ends of the composite rods. The wedge plugs are inserted into termination fitting having a termination fitting body with an aperture at a proximal end for receipt of the bundle of composite rods and having an internal cavity that flares outwardly from a proximal end to a distal end to closely receive the wedge plug with the composite rods imbedded therein. A closeout nut is used to retain the wedge plug in the termination fitting body. The invention further provides method of manufacturing composite tension members.

  • Patent number: 5730485
    Abstract: The invention provides a floor assembly for replacing oak board floor constructions. The floor assembly includes floor boards that are installed in the same manner as oak floor boards, but that are made of more readily available materials. In one embodiment the floor boards are made of an inexpensive wood material core encased in a shell made of fiber reinforced plastic composite material. The core and the fiber reinforced plastic composite material are co-pultruded so that the shell integrally bonds to the core member and provides a seamless protective skin for the core member.

  • Patent number: 5702151
    Abstract: A vehicle body, such as a truck or trailer body, comprises an intermodal container, or the like, having a lightweight, leakproof, damage resistant and corrosion resistant wall construction. The wall construction includes a sheet-like panel reinforced with vertical stiffeners. The panel and the stiffeners are made of nonmetallic material and the stiffeners are adhesively bonded to the panel. The stiffeners each include an outwardly facing surface having a generally parabolic shape.

  • Patent number: 5678715
    Abstract: An intermodal shipping container including a top wall, a bottom wall, opposite side walls, and a composite frame structure including upper and lower longitudinals interconnecting the side walls with the top and bottom walls, and a pair of stacking frame assemblies for supporting the weight of one or more other containers. Each stacking frame assembly includes a pair of vertical stacking posts each integrated into one of the side walls and a horizontal crossmember integrated into the top wall. The stacking posts and the crossmember are pultruded of composite material, and the stacking post can include layers of different material to optimize performance. Each of the stacking frame assemblies also includes a pair of upper connector assemblies at the intersections between the upper longitudinal members, the stacking posts, and the crossmember, and a pair of lower connector assemblies at the intersections of the lower longitudinal members and the stacking posts.

  • Patent number: 5449081
    Abstract: A modular insulated intermodal freight container or other vehicle body constructed primarily of lightweight non-metallic composite material. The container includes a frame constructed substantially of pultruded composite frame components, and modular panels including pultruded composite panel members that are adhesively bonded together to form top, bottom and side walls. The walls are adhesively bonded to the frame to provide a substantially fastenerless container construction having light weight and good thermal and structural properties.

  • Patent number: 5403063
    Abstract: A floor for a vehicle body, the floor including a plurality of modular floor panels adhesively bonded to one another in adjoining series relation to form joints therebetween. Each floor panel includes an integrally formed panel member that is pultruded of composite material and that includes a floor section which interfits with the floor sections of adjoining panels. The floor section includes spaced apart upper and lower sheet members interconnected by webs having filamentary reinforcing material predominantly oriented lengthwise of the panel member to improve structural and thermal performance of the panel member. The floor section can be optionally filled with an insulating material. The panel member of each floor panel also includes a reinforcing section for resisting bending moments applied to the associated floor section and for reinforcing one of the joints.

  • Patent number: 5403062
    Abstract: A vehicle body including top, bottom and opposite side walls each including a plurality of modular panel members adjoining one another in series relation. Each panel member is an integral pultrusion and includes a pair of spaced apart sheet members, a pair of spaced apart webs interconnecting the sheet members, and wedge-shaped male and female members that interfit with the male and female members of adjoing panel members. Adhesive material is provided at the joints between panel members to bond the panel members together. To prepare suitable bonding surfaces for the adhesive, fabric material can be pultruded as an integral part of the male and female members and peeled off prior to application of the adhesive to reveal clean, gritty textured surfaces.
