  • Patent number: 9564728
    Abstract: An electrically conductive structural connection employs a pass through or fastener having a first diameter. A fastener hole, with a second diameter larger than the diameter of the pass through, extends through a thickness of a structure and receives the pass through. A bushing having a diameter and a thickness to fit between the first and second diameters extends though and past the thickness of said structure. When the feedthrough is compressively secured to the structure, the bushing expands radially between the first diameter and the second diameter to maintain at least one contact point between the fastener and the structure.

  • Publication number: 20150057118
    Abstract: A method for providing a link-plate chain having increased strength by stretching the chain between a pair of spaced, rotatable conical pulleys, wherein the link-plate chain is stretched in opposite directions of rotation of the conical pulleys. The opposite stretching operations impart deformation forces on at least the link-plates and/or rocker pressure pieces that interconnect link plates of the link-plate chain. The deformation forces cause parts of the chain to undergo plasticization regions of the chain components and that result in increased chain strength.

And, the assembling base includes a first portion and a second portion vertically formed at two opposite ends thereof for respectively engaging with the first and second clamping components. Here, the first and second clamping components together clamp and restrict the chain. The second clamping component has a tubular shape for being inserted by the penetrating shaft, and then, the driving shaft can further be locked into the second clamping component. By turning the driving shaft, the penetrating shaft can be forced to push out a pin, which is used for jointing the inner and outer link plates of the chain.

  • Patent number: 8136339
    Abstract: The oil-free chain is obtained by connecting a pair of inner link plates which are connected by oil-impregnated bushings and a pair of outer link plates, which are connected by pins inserted into adjacent oil-impregnated bushings of adjacent inner link plates alternately. The oil-impregnated bushing is obtained by impregnating a bushing made of a metal sintered body with perfluoropolyether having a kinematic viscosity at 40° C. equal to or higher than 350 mm2/s. The bushing is impregnated with perfluoropolyether having a kinematic viscosity corresponding to the operating temperature of the oil-free chain.

  • Publication number: 20110302900
    Abstract: An element is provided for a cable carrier device which is constructed and arranged to carry cabling components such as cables, lines, hoses and the like between a first connection point and a second connection point. The element is formed from a material including at least one plastic and a filler. The filler includes three-dimensional geometrical carbon-based structures having nanometer-scale dimensions. In some arrangements, the carbon-based structures are carbon nanotubes formed of carbon atoms. Accordingly, the element is capable of dissipating electrostatic charges of the cable carrier device. Thus, the corresponding cable carrier device is suitable for working environments that are to be protected from electrostatic effects.

  • Patent number: 8074438
    Abstract: A link chain comprises a chain link including two shank portions and two arc portions connecting the two shank portions. The two shank portions and the two arc portions define an interior space of the first chain link; and a dividing element extends inwardly from an inside surface of one of the two shank portions and extends inwardly from the inside surface of the other shank portion. The dividing element divides the interior space into two movement spaces, and the dividing element has a centerline, and the centerline is not a straight line perpendicular to the shank.

  • Patent number: 8038559
    Abstract: The end faces of a first pin contain bulging curved faces having an egg-like shape, when viewed along a chain width direction. Each bulging curved face includes a first end portion, a second end portion and a maximum width portion with respect to a chain advancing direction. With respect to perpendicular directions, the distance between the center of the maximum width portion and the first end portion is relatively large, whereas the distance between the center of the maximum width portion and the second end portion is relatively short. It is possible to enlarge the surface area of the bulging curved face.

    Abstract: Drive dog chains are assembled with alternating universal inside attachment links and outside sidebars and riveted pin connections. The universal inside attachment links have full size end sections and central sections of reduced height. Filler attachments are attached with machine screws to the central sections. Upper surfaces of the filler attachments are level with upper surfaces of the end sections and upper surfaces of the outside sidebars. Filler attachments are removed from selected ones of the center sections and replaced with pusher attachments secured at an end of each selected center section. A drive dog chain is manufactured and stored in uniform strands. Upon ordering, the pusher attachments replace the filler attachments at selected spacings on the chain.
