  • Patent number: 6123646
    Abstract: A treadmill for walking exercise or medical testing has the the usual frame mounting rollers around which an endless belt is driven through a lower course and an upper course, the upper course of the belt being supported by an improved deck particularly adapted to rest on longitudinal support members of the frame.One improvement lies in connecting one end of a planar deck to a anchor member by a flexible hinge, the member being attachable to the frame and the flexibility of the hinge allowing the deck to yield to the impact of a user's tread both vertically and longitudinally of the deck.Many available treadmills are designed to receive a standard deck which is essentially a rectangular plank bounded by flat surfaces which enclose a prismatic volume. The present deck is rectangular and planar but has recesses rabbetted along its underside opposite the supporting frame members, the recesses being filled with strips of compressible, elastomeric material located within the cubic volume of the standard deck.

  • Patent number: 6024341
    Abstract: An energy absorbing guardrail crash attenuator system comprises a row of two or more compressible sections comprising left and right curved, metal side panels. The row of compressible sections extends in an axial direction from a front end and terminates in a back end that is engagable with a rigid backup. When the row is impacted by a vehicle in the axial direction, the compressible sections bend outwardly and absorb energy. When the row is impacted in a direction that is off of the axial direction, the row redirects the vehicle so as not to hit the "coffin corner" of the rigid backup. The front ends of the left and right metal panels are flexibly joined while the back ends are pivotly joined to the rearwardly adjacent section. The panels may have panel bending modifications for facilitating the axial compression of the sections. The row may have an axial movement guide to restrict lateral movement of the row of compressible sections.

  • Patent number: 6003874
    Abstract: An apparatus for sealing a rotary tube drum of a furnace to another furnace component. Two concentric resilient metal ring segments are provided on a disk to comprise the sealing elements of the present invention. A plurality of springs arranged as a ring apply pressure to the disk and ring segments to ensure a consistent and self-adjusting seal between the joined components. Links located circumferentially about the disk limit lateral movement, yet allow axial movement, of the seal. It is thereby possible, according to the present invention, to provide a resilient seal between a rotary tube and another component of a furnace that yields a self-adjusting gas-impermeable seal between the mating components.
