Abstract: The present invention employs an arrangement of multiple containers for marinating food. The container arrangement includes an inner container having a bottom wall and side walls which define a food holding chamber. A plurality of apertures are provided in the bottom wall of the inner container for marinade to passage. The inner container further has a noncircular cross sectional configuration defining a plurality of bottom corners. An outer container similarly has a bottom wall and side walls defining a marinade holding chamber for holding a given level of marinade. The outer container is configured in to accept the inner container. Alternatively, the side walls support the inner container in an elevated position on rotation thereof relative to the outer containers.

Abstract: The present invention provides a dunnage rack including a molded pallet having a plurality of legs with caster supports integrally secured thereto, and to a method of forming such a dunnage rack. The dunnage rack is formed by first providing a mold for the pallet. A lower end of each leg portion of the mold is then blanked off with a caster support. The caster supports include a base plate arranged to support a caster and a plurality of flanges which extend upwardly from the edge, of the base plate into the mold. The flanges have an irregular surface. In a preferred embodiment, the irregular surface is formed by a plurality of openings or apertures. A molding material introduced into the mold engages the flange irregular surface to secure the caster support to the pallet legs.

Abstract: The present invention is a shelving system having height adjustable shelves. The shelving system includes a plurality of elongated support posts having recesses spaced along the longitudinal axis. At least one resilient support post clip is attached to each support post within a recess to provide a shelf support. A shelf member having recesses at least partially accepting the post clip, is positioned in detachable nesting relationship with the support clips.The shelf member further includes an upper surface having alternating transverse ribs and recesses, and a lower surface having alternating longitudinal ribs and recesses. The ribs serve to reinforce the shelf member both longitudinally and transversely.Each shelf member further comprises an outward projecting support rail extending along one or more edges of each shelf member. A connecting mechanism simultaneously engages the support rails of adjacent shelf members and retains the adjacent shelf members in fixed relation with each other.

Abstract: In order to form concrete pipe of uniform density in apparatus where a packer head packs concrete into a mold to form the pipe, the horsepower of the drive motor driving the packer is sensed and used to adjust the rate of concrete supply such as to insure a constant horsepower as the packer is moved from one end of the pipe mold to the other.

Abstract: An apparatus for forming concrete articles of uniform density, which includes means for forming concrete into the form of the articles, and means for sensing the density of concrete in each area of formation in the forming means as the article is being formed, comparing the sensed density to a preset density, and compensating for variation of the sensed density from the preset density responsive to such comparison, such that the density of concrete in each area of formation in the forming means as the article is being formed equals the preset density.
