  • Patent number: 4832105
    Abstract: Method and apparatus for producing an investment casting from molten material by filling a cavity in a mold with the molten material utilizing at least one porous member in the inlet conduit system of the mold, the porous member enabling evacuation of the mold cavity, through the inlet conduit system and the porous member, and having a structure including pores small enough subsequently to support the molten material upon the porous member by surface tension, with the molten material closing off essentially all atmospheric communication between the inside and the outside of the mold cavity, to thereby prevent passage of the molten material into the mold cavity until the method and apparatus subsequently raises the pressure outside the mold to provide a higher pressure outside the mold cavity and create a differential pressure between the inside and the outside of the mold cavity sufficient to overcome the surface tension and urge the molten material to pass through the pores of the porous member and fill the

  • Patent number: 4765493
    Abstract: Means for installing, adjusting and securing tracks of a gravity feed mechandise rack. Preferably, a strip bearing slots is spaced slightly above the horizontal support surface of each of the front and rear cross members of a shelf for the rack. Each track has a pair of cooperating side rails, preferably with in-turned lower edges. During assembly, each end of a track slides into slots while the in-turned edges slide between a strip and a support surface. The sizes of the tracks, strips and slots are such that the tracks may be placed into a locked position by simple longitudinal manipulation.

  • Patent number: 4729484
    Abstract: A pallet rack construction comprising beam and upright members which can be locked together rigidly to form a storage rack of superior strength. The improved rigidity is attributable to a novel connector on the end of the beam member which fits into a slot in the upright and by wedging action pulls the beam both endwise (axially) and sidewise (laterally) with respect to the upright.
