  • Patent number: 9873303
    Abstract: A strut-type damper is disclosed. The damper has a shock absorber having a housing with a telescoping piston rod, a coil spring, an upper spring seat operably coupled to a distal end of the piston rod, and a lower spring seat operatively coupled to the housing. The upper and lower spring seats capture the coil spring therebetween. The lower spring seat has a base portion having an opening for receiving the housing and is fixedly securable to the housing. A generally circumferential wall portion extends from the base portion and forms a catcher for catching a broken portion of the coil spring if the coil spring fractures. An impact absorbing structure is formed on the lower spring seat adjacent both of the catcher and the base portion, and is configured to be crushed in the event of a fracture of the coil spring.

  • Patent number: 4074733
    Abstract: Flexible electrode material for use in salt water batteries, and a method and apparatus for the continuous manufacture of such material, are disclosed. The material is manufactured by guiding a strip-shaped mesh, e.g., a copper wire gauze, from a supply position through a bath of molten coating material, e.g. lead chloride, and vertically upwardly from the bath to cause the coating material to become deposited on the mesh, which is subsequently cooled. For guiding the mesh, the apparatus employs first guide rollers for guiding the mesh on a path of travel extending downwardly from the first guide rollers to a second guide roller, made of graphite, immersed in the bath, and third guide means for guiding the mesh upwardly from the graphite roller. Hydraulic jacks are provided for raising and lowering the bath to and from an elevated position in which the graphite roller is immersed in the bath.

  • Patent number: 4016339
    Abstract: A battery electrode structure of flat configuration comprises a cast mass of electrochemically active material, said mass having contained therein and exposed opposite surfaces thereof an open-mesh electrically conductive structure adapted for connection to a battery terminal. An open-mesh electrically conductive support member in the mass and in contact with the exposed electrically conductive structure maintains electrical conductivity throughout discharge to ensure maximum use of the active material.
