Abstract: Embodiments of the present technology include molding processes for metallic foams, apparatuses, and products. An example method includes placing an uncompressed charge of conductive metal foam into a cavity disposed on a first tool, wherein the first tool is located on a first portion of a compression mold apparatus, translating the first portion of the compression mold apparatus towards a second portion of the compression mold apparatus so as to compress the uncompressed charge of conductive metal foam, creating a compressed charge of conductive metal foam, and overmolding around and through the compressed charge of conductive metal foam with an overmolding material.

Abstract: A high security lock includes a housing defining an interior chamber having a longitudinal chamber axis and a keyway axially through the housing into the chamber. A cam arrangement within the chamber defines an access in axial alignment with the keyway. The cam arrangement includes a plurality of stationary raceway cams arranged in parallel planes and concentric to the chamber axis. Each raceway cam has a radially-inward surface forming a bearing raceway. The cam arrangement further includes at least one stationary locking cam arranged in a plane parallel to the raceway cams and concentric to the chamber axis. The locking cam has no such bearing raceway. A tumbler assembly is disposed within the chamber and cooperates with the cam arrangement for selective rotational movement within the access about the chamber axis. The tumbler assembly includes a plurality of bearing elements supported for axial movement relative to the cam arrangement.

Abstract: An essentially pickproof padlock has a housing defining an interior chamber and a keyway with a stacked parallel arrangement of multiple annular cam rings fixed concentrically within the housing. The radially inward annular surface of each cam ring is formed with a respective raceway of a predetermined annular extent and disposition relative to the chamber. A tumbler assembly is disposed within the cam arrangement for selective relative rotational movement. The tumbler assembly has a plurality of slidable pins each with a head portion forming a bearing element. An associated key is formed with a plurality of parallel axial recesses for receiving the pins of the tumbler assembly, each recess being of a selected respective length terminating at a shoulder to collectively engage and move the head portions of the pins into respective operative dispositions within corresponding ones of the raceways wherein the tumbler assembly may be rotated by the key between locked and unlocked dispositions.
