  • Patent number: 6336414
    Abstract: A table construction includes a base having a pair of legs secured together by a transverse beam, and a tabletop pivoted to a top of the legs for movement between a horizontal use position and a vertical storage position. A pair of support arms are pivoted to the top of the legs for selectively holding the tabletop in the horizontal use position. The support arms are spring-biased and pivoted at an angle so that they counterbalance a weight of the tabletop during its pivotal movement. Ganging connectors on opposite ends of the tabletop automatically interconnect adjacent tables upon pushing adjacent tables together. The legs each include first and second castings that bolt together and that are arranged to matably nest when tables are moved together for storage. A utility raceway structure attached to the base includes a frame that defines upper and lower chambers and further includes upper and lower lockable doors providing separate access to the upper and lower chambers, respectively.

  • Patent number: 6000738
    Abstract: A vehicle bumper includes a hollow tubular wall structure adapted to span the front or rear end of an automotive vehicle so as to absorb crash forces when the vehicle is involved in a crash situation at vehicle speeds above some predetermined speed level, e.g., five miles per hour. The hollow tubular wall structure includes an outer wall disposed to receive the crash force, an inner wall connectable to the vehicle, and four connector walls joining the outer wall to the inner wall. The four connector walls bend at a controlled rate to absorb crash energy. The outer and inner walls have aligned air openings adapted to conduct ram air to the vehicle radiator.

  • Patent number: 5165355
    Abstract: A system for automatically producing pantyhose garments from elongated tubular fabric blanks, each having a toe end portion and a welt or band end portion. Randomly oriented blanks are sequentially removed from a supply reservoir, oriented in a predetermined manner, and conveyed to a positioning and transferring assembly which orients, removes creases and pleats and properly positions a pair of blanks on the clamping assemblies of a pantyhose seaming machine. The pair of clamped blanks have the welt end portions severed, and severed edges seamed by sewing instrumentalities to define the panty portion of a pantyhose garment. The pantyhose are transferred to a machine where the toe ends are closed by seaming.

  • Patent number: 5080410
    Abstract: A rollformed tubular vehicle bumper beam is fabricated of ultra-high strength steel and has a plan view sweep value of more than 10. The bumper beam has a cross-sectional configuration comprising an upper wall, a lower wall, an outer wall, and an inner wall. Inner portions of the upper and lower walls are angled, respectively, downwardly and upwardly. This configuration permits fabrication of the bumper beam by rollforming without stretching the outer wall to a point where it would be damaged.

  • Patent number: 5061108
    Abstract: The present invention provides an arrangement for attaching a flexible elastomeric panel integrally formed with one or more female connectors to an automotive body support surface having one or more associated male connectors in a blind assembly connection. Each female connector comprises a cutting-tooth shaped notch molded in an attaching flange of the panel while the male connector comprises a elongated stem projecting from the support surface. The elongated stem includes a backing plate positioned in parallel spaced relation to the support surface defining a layered gap therebetween. The panel flange is moved into flush contact with the support surface enabling the support flange to be received in a layer-like gap with the stem adapted to be received in a lean-in passage of the female connector.
