US Patent:

42397960, Dec 16, 1980

Filed:

Jun 21, 1979

Appl. No.:

6/050902

Inventors:

Henry Shanoski - Akron OH
Richard M. Griffith - Akron OH

Assignee:

The General Tire & Rubber Company - Akron OH

International Classification:

B32B 518
B29D 2700

US Classification:

428315

Abstract:

A method is disclosed comprising in-mold coating a structural foam part made from a thermoplastic aromatic polycarbonate resin or a thermoplastic ABS polymer resin with a thermosetting in-mold coating composition at a pressure of from about 25 to 50 p. s. i. and at a temperature not in excess of about 200. degree. F. for from about 1 to 10 minutes, preferably for from about 1 to 3 minutes, to provide hard, smooth and adherent coatings, said thermosetting in-mold coating composition comprising an ethylenically unsaturated polyester resin and an ethylenically unsaturated monomer(s) catalyzed with an organic perioxide initiator including an accelerator for the initiator.

Appl. No.:

5/620515

Inventors:

Willem J. van Essen - Tallmadge OH
Henry Shanoski - Akron OH
Richard M. Griffith - Silver Lake OH

Assignee:

The General Tire & Rubber Company - Akron OH

International Classification:

B29C 500
B29D 900

US Classification:

428 63

Abstract:

An in-mold coating composition is disclosed which includes (a) an isocyanate-terminated material containing an excess of reactive isocyanate groups and (b) a material selected from the group consisting of a composition containing reactive hydrogen atoms, generally hydroxyl groups, and a catalyst capable of trimerizing the terminal isocyanate groups. The coating composition is applied to a molded substrate, such as an FRP part, by placing a charge of the composition in the mold on the substrate, the charge being sufficient to provide a coating having a thickness less than about 20 mils. Appropriate pressure is then applied to the charge, such as by closing the mold, so that the coating composition is forced to cover substantially the entire surface area of the substrate, filling any surface defects. The composition is cured to yield a crosslinked, isocyanate-based coating which adheres tightly to the substrate.

Appl. No.:

6/484760

Inventors:

Richard M. Griffith - Akron OH
Henry Shanoski - Akron OH

Assignee:

The General Tire & Rubber Company - Akron OH

International Classification:

B29C 100
B29C 900

US Classification:

264255

Abstract:

An SMC (FRP) molding is coated with a minimum amount of an IMC composition by skewing one of the mold halves during the initial IMC molding cycle to effect a scissoring action, the fulcrum being at or about the IMC injection point or placement to spread or wipe the IMC over the surface of the SMC part and then effecting at least substantial parallelism of the mold halves during the remaining IMC cycle of coating and curing the IMC.

Appl. No.:

6/661635

Inventors:

James F. Stevenson - Hudson OH
Thomas E. Codispoti - Akron OH
Richard M. Griffith - Akron OH
Harry L. Hutch - Stow OH

Assignee:

GenCorp Inc. - Akron OH

International Classification:

B29C 4792
B29C 4978

US Classification:

425135

Abstract:

A rotatable accumulator roll which may move substantially horizontally or vertically is disposed between the die of an extruder and a take-away conveyor to minimize the effects of output surging of the extrudate from the die of the extruder in order to maintain substantially the dimension of the extrudate as delivered to a constant speed take-away conveyor. Variable force is applied to the roll to maintain tension on the extrudate.

Appl. No.:

6/307401

Inventors:

Thomas E. Codispoti - Akron OH

International Classification:

B29D 704
B29H 300

US Classification:

264171

Abstract:

A puncture sealant package for incorporation into a pneumatic tire is formed by coextruding a puncture sealant, and a skin forming material. The ribs are formed in an initially circular package profile as chords. After flow in a sheet die, the chords form divider ribs making small angles with the encapulating skin. The compartments formed by the ribs prevent flow of the sealant toward the center of a tire.
