  • Publication number: 20220258962
    Abstract: The segmented cover is made of juxtaposed cover segments mounted over a wastewater reservoir. Floating beams define each of these cover segments, and a floating membrane is removably mounted to the floating beams over each of the cover segments. The floating beams are enclosed in a common sealed tubular envelope, which is connected to gas-impermeable connections joining the floating beams to a wall-covering skirt and to the perimeter walls of the reservoir. Because of the sealed continuous tubular envelope enclosing the floating beams, the wall-covering skirt and the gas-impermeable connections, each segment of the cover is independently sealed from outside environment and from an adjoining segment. Biogas collection from the wastewater reservoir can be maintained even when one segment of the cover is open.

  • Patent number: 8196979
    Abstract: A bumper system includes an injection molded energy absorber of polymeric material having hollow longitudinally-spaced lobes configured to crush and absorb energy during a pedestrian impact, and straps interconnecting adjacent lobes. The lobes are particularly sized and dimensioned, including potentially external ribs and/or apertures in corners, to provide a relatively uniform impact energy absorption during an impact stroke during crush of the shear walls of the lobes, such as within +/?30% or more preferably within +/?20% of a desired amount regardless of a specific location of impact, along a selected center portion of the energy absorber. A reason for the uniformity is to promote pedestrian safety regardless of the specific location where a pedestrian's leg strikes the energy absorber.

  • Patent number: 8123263
    Abstract: A tube comprising an outer tube section with a stepped outer surface and an inner tube section, with the inner tube section being located within the outer tube section. The tube also comprises a spanning section connecting an end of the outer tube section to an end of the inner tube section. The outer tube section is longer than the inner tube section, whereby, upon undergoing a longitudinal impact, the outer tube section crushes predictably and sooner than the inner tube section upon the energy management tube receiving forces from the longitudinal impact, to thereby create a first energy absorption level during crushing of the outer tube section alone and a second energy absorption level during crushing of the outer tube section and the inner tube section.

  • Patent number: 7810602
    Abstract: An energy-absorbing system includes two formed and sealed components bonded together to form crush boxes that entrap air for controlled distribution during an impact, and an activator system adapted to extend the crush boxes in the event of a vehicle crash. Channels interconnect the crush boxes for optimal control of lateral flow of air for lateral energy distribution. The components can be thermoformed, injection molded, or otherwise formed. By this arrangement, the crush boxes provide a first level of static energy absorption when impacted in an undeployed state such that energy is absorbed at a first rate and stroke. Also, the crush boxes can be extended to provide a second level of static energy absorption when impacted in a vehicle crash (i.e., the activator system is energized and the crush boxes extended or “deployed”) such that energy is absorbed at a one or more different rates and strokes.

  • Patent number: 7699367
    Abstract: An energy absorber includes a base flange and elongated crush boxes that to form a substantially continuously face surface on the energy absorber. Back straps are attached across a back of the crush boxes to prevent unacceptable spreading of the side walls of the crush boxes during an impact. The back straps can be integrally formed when the energy absorber is molded, and can include a living hinge at one end and a free end that can be bent over and snap attached during post-molding assembly without additional secondary operations. Alternatively, a separate wall-stabilizing thermoformed component is sandwiched between the energy absorber and beam.

  • Patent number: 7552955
    Abstract: A hybrid bumper system includes a polymeric reinforcement beam with end sections and structural covers attached to the end sections to considerably strengthen the end sections. Bracketry stably supports the reinforcement beam on a vehicle frame. A fascia covers at least part of the reinforcement beam but leaves a portion of the structural covers in a visible position. The structural covers are treated for aesthetics, such as by painting, chroming, or other surface treatment. In one aspect, the beam includes a molded polymeric beam component, structural L-shaped covers attached to its end sections, and a tie bar along its rear side that stiffens and rigidifies a center of the polymeric beam component. In another aspect, a tow bar or rail-to-rail metal reinforcement beam front system (or rear with tow bar) is incorporated.

  • Publication number: 20090080978
    Abstract: A reservoir is covered by an impermeable flexible floating membrane cover through which is mounted a hatchway. The cover is movable as a raft over the content of the reservoir for positioning the hatchway at one location or another. In use, a pumping and agitating device is introduced inside the reservoir through the hatchway and operated at one location, and then at another location for pumping, mixing and liquify the entire content of the reservoir without aerating the content of the reservoir. The fertilizing properties of livestock manure in storage inside the reservoir are thereby preserved.
