  • Publication number: 20180273291
    Abstract: An insulation system is configured for mounting to corrugated walls such as the walls of a shipping container. A first end has a first coupling surface and a second end opposite the first end has a second complementary coupling surface. Mating alignment portions are on a top surface of the panel and on a bottom surface of the panel. The second face includes a corrugated surface with a protruding first surface parallel to the first face, a recessed second surface spaced apart from and parallel to the first surface, and third and fourth surfaces extending between the first surface and the second surface, the third and fourth surfaces being orthogonal to the first and second surfaces.

  • Patent number: 7300586
    Abstract: An activated carbon composition is disclosed, which includes an activated carbon and a carboxylic acid containing compound. The activated carbon composition is prepared by immersing an activated carbon in an aqueous solution of a carboxylic acid containing compound. The activated carbon composition is used for purifying aqueous solutions by providing a bed of the activated carbon composition and passing the aqueous solution through the bed of the activated carbon composition. The aqueous solution is passed through the bed such that the flow of the aqueous solution to be purified into the bed and the flow of purified aqueous solution from the bed has a pH differential less than ±1 pH.

  • Patent number: 6612635
    Abstract: A system for storing items on a vehicle bed utilizing a platform fixed relative to the walls of the bed. The platform is spaced from the bottom of the vehicle bed to from a chamber. First and second tracks connect to the platform within the chamber. A ramp slidingly moves along the track into a first position where the ramp rests on the ground surface or into a second position where the ramp lies in the chamber. The gate connected to the ramp closes the chamber in the truck bed beneath the ramp.
