Filed:

Dec 31, 1991

Appl. No.:

7/816150

Inventors:

William L. Welch - Houston TX
Don W. Sluder - Lake Jackson TX
Richard L. Cory - Lake Jackson TX

Assignee:

Apt, Inc. - Cypress TX

International Classification:

B29C 3900

US Classification:

249 63

Abstract:

The present invention is directed to a reuseable mold for casting a hollow form made of an aggregate filled thermosetting resin. The reuseable mold includes an outer mold, made from sheets of thermoplastic resin, and an inner mold, also made from sheets of thermoplastic resin, having a base with plugable opening(s) for connecting an air supply for popping the inner mold from the cast hollow form fabricated in the reuseable mold. The sheets are preferably 1" sheets of polyethylene.

US Classification:

428117

Abstract:

The present invention is directed to composites and multi-composites of a prefabricated core of a cellulosic honey comb filled with a rigid polyurethane and layers of fiber saturated thermoset resins. More specifically, the present invention is directed to composites and multi-composites of a cellulosic honey comb filled with rigid polyurethane prefabricated core and a fiber reinforced material, either fibers or woven fibers selected from the group consisting of glass, polyester, carbon and aramid fibers as a mat or cloth saturated with a thermoset resin selected from the group consisting of catalyzed polyester, amine catalyzed epoxy, catalyzed vinyl ester and acid catalyzed furan resins.

International Classification:

B29C 3926

US Classification:

249134

Abstract:

The present invention is directed to reusable molds which are used to mold various pieces including a modular contained machine foundation unit. Most pieces are molded as a hollow form which surrounds vertically extending reinforcement rods and is filled with a fortifying material to secure the hollow form to a slab. The hollow form is preferably made of an aggregate filled thermosetting resin which is a corrosion and chemical resistant material. More particularly, the present invention is directed to unique products which may be easily secured to a slab or foundation.
