Abstract: An investment casting mold base has an enlarged, ellipsoidal-shaped body overlying a frusto conical-shaped body on the base. The enlarged body will form a molten metal staging cavity between a funnel cavity at the entrance of the mold formed by the frusto conical body and sprue channels leading to the article cavity in the mold. The staging cavity eliminates backup of molten metal at the mold entrance and possible spillover of the metal from the crucible mated to the mold during the centrifugal casting operation.

Abstract: Means for supporting papers, forms and the like on the pin type feed mechanism of a computer printer or the like is provided which comprises a pair of flexible strips each having near one edge thereof a plurality of regularly spaced holes for engaging the sprockets of the pin type feed mechanism of a computer printer or the like, and near the other edge thereof a strip of non-setting, non-permanent adhesive for firmly, but removably, securing the said papers for advancement into the printer.

Abstract: A three layer laminated plastic cushioning material having a substantially flat central layer with sealed air pockets formed on both sides of the central layer between the central layer and layers positioned on opposite sides of the central layer.

Abstract: A cargo pallet, pallet support and restraint system which distributes the supporting forces equally over the bottom of the cargo pallet, even though the cargo load forces are concentrated and unevenly distributed over the pallet. The pallet is supported by a system of multiple ball or roller assemblies acting in conjunction with an interconnected hydraulic pallet support system to produce a multiplicity of equal lifting forces acting over the bottom surface of the pallet. Rails located at the pallet periphery restrain the pallet's upward movement and thereby introduce forces opposing those of the hydraulic pallet support system. The force and torque interactions among the areas of load concentration, the interconnected hydraulic pallet support system, the restraining rails, and the pallet structure rigidity, distributes the concentrated load evenly over the bottom of the pallet by hydraulically maintaining an equal supporting force from each of the underlying pallet support ball or roller assemblies.
