Abstract: A portable apparatus adapted to be moved to the edge of a concrete pad that needs to be restored to a horizontal condition. The apparatus includes a generally upright frame and a lifting platform that is attachable to the bottom of the frame (with bolts or the like). The platform has a forwardly projecting shelf that is placed under an exposed edge of the pad. A pair of hydraulic cylinders are mounted on the frame for selectively pushing downward on a yoke. Reaction loads from the downward push on the yoke are accommodated by the concrete pad. A chuck is mounted on the yoke for the purpose of engaging a generally linear member that is pushed into the ground to create a deep "foundation" for lifting the concrete pad with respect to the surface. A preferred linear member for this purpose is one or more sections of heavy reinforcing rod of the type that is commonly used to reinforce large concrete structures.

Abstract: A process for dense packing on a conventional pallet three-cubic-foot bags containing a lightweight, loose material that will flow within that bag, by a stacking pattern where a pair of bags are arranged alongside and offset from one another on the pallet to make up each stack layer, with successive layers rotated ninety degrees (90.degree.) from the layer below; applying, in turn, to each bag a downward force, as by a person moving his feet thereon, to evacuate air from that bag and to shift the contents to fill in gaps or openings in the layer below; and securing that stack to the pallet for transport; and a stack of three-cubic-foot bags containing a lightweight, loose material by a practice of the process of the invention.
