Abstract: A pallet (10) includes a deck (14) and a plurality of legs (12) extending downwardly from the deck (14). The deck (14) includes recessed and raised areas (16, 18), wherein the raised areas (18) lie in a substantially horizontal top plane (T), and the recessed areas (16) lie in a substantially horizontal bottom plane (B). The raised and recessed areas (18, 16) are interconnected to each other by an upstanding wall (22).

Abstract: A reinforced pallet (10) includes an upper surface (11) and a pair of opposing support sides (14, 15). The pallet (10) also includes at least one reinforcing bar channel (50) and a reinforcing bar (40) received within reinforcing bar channel (50). A twin-sheet pallet (10) is formed vacuum-forming a first plastic sheet (33a) to a first mold section (30) and a second plastic sheet (33b) to a second mold sheet (31), wherein a preselected portion of the second mold section (31) is sealed such that the second plastic sheet (33b) is not vacuum-formed. The mold sections (30, 31) are then moved together and the sheets (33a, 33b) are compressed together at preselected locations. A thermoformed, plastic pallet (10) for bearing and positioning a load, also includes and a retaining wall assembly (90) carried by the upper surface (11); the retaining wall assembly (90) including a wall-receiving slot (91) in the upper surface (11) and a retaining wall (92) received and positioned within the slot (91).

Abstract: A pallet (10)for use in bearing a load from material requiring a circulation of air during storage or shipment thereof, includes a thermoformed plastic body (11) have a plurality of ventilation apertures (30,31) therethrough, and a plurality of strengthening grooves (32, 40, 50) integrally formed in the body (11) and juxtaposed to the ventilation apertures (30,31). In use, the pallet (10) may carry a container (14) thereon and the material is contained within the container (14). The container (14) includes at least two opposing walls (52) and at least one aperture (53) in each of two opposing walls (52). The pallet (10) includes a plurality of downwardly extending feet (10, 21, 22, 23) to raise the pallet (10). At least one of the apertures (53) of the container (14) generally aligns with at least one of the ventilation apertures (30, 31) of the pallet (10) when the container (14) is stacked on the pallet (10).

Abstract: A stackable and collapsible container (10) includes a wall assembly (12) which includes a plurality of opposing panels (20, 21), and hinge means connecting each panel (20, 21) to at least two adjacent panels (20, 21).

Abstract: A tool (10) for the installation and removal of back pressure valves or plugs in a wellhead under pressure conditions to permit repair and replacement of wellhead outlet valves. The tool (10) comprises an elongate cylindrical housing (31, 32, 33) in which a manipulator rod (30) is slidably mounted in axial alignment therewith. The tool (10) includes a piston (55) which is sleeved about the rod (30) and adapted to be selectively clamped thereto. The manipulator rod (30) is provided at one end with a back pressure valve of plug (84) attached thereto. The tool (10) includes a fluid controls system which is connectable to an external fluid pressure source (P) or the pressure of the well itself.

Abstract: A garbage compaction apparatus includes a packer housing having a loose garbage receiving bin and a compacted garbage storage bin. A packing channel communicates with both bins and has a ram reciprocally movable therein for moving garbage toward and into the storage bin. A movable wall within the storage bin is biased toward the outlet opening of the packing channel such that upon the accumulation of sufficient garbage within the storage bin, the insertion of additional garbage by the ram causes the wall to retract against the urging of the biasing mechanism whereby the accumulated garbage in the storage bin is maintained in a compacted state. The packer housing may be supported on a vehicle with the receiving bin situated forwardly of the storage bin and with the packing tube extended rearwardly to introduce garbage into the storage bin at the rearward end thereof so as to force the movable wall forwardly within the storage bin.
