Abstract: Four embodiments of a sport swing harness (10, 10',10",10"') are disclosed. The sport swing harness (10,10',10",10"') is fabricated from a flexible, inelastic material. The harness (10,10',10",10"') includes at least one loop (16,16',16",16"') which extends around at least one shoulder of a trainee (14). A strap (18) of the same flexible inelastic material snaps over the back and under the second shoulder of the trainee (14). The end (22) of the strap (18) is held by the trainee (14) in his or her leading hand (24). The third alternative embodiment (10"') incorporates the harness (10'") into a sporting garment (32), such as a sweater, coat, vest or shirt.

Abstract: A test mold assembly for evaluating the surface deformation tendency of a coverstock bonded to a reactive plastic formulation to voids in the formulation including a base adapted to support a coverstock and spaced side walls extending upwardly from the base to define a mold cavity for receiving foam precursors. The assembly further includes a lid adapted to form the top of the mold cavity and having a cover portion disposed spaced from the base. The lid includes a plurality of integral projections extending downwardly from the cover portion into the mold cavity a predetermined distance to create voids in the foam. A method of making a foam void model for evaluating the surface deformation tendency of a coverstock bonded to a reactive plastic formulation to voids in the formulation is also disclosed.

Abstract: A method for molding a thin walled plastic shell utilizes the following apparatus. An apparatus (40) for molding a thin walled plastic shell includes a mold box (42) having an inner mold surface (48). A powder box (52) includes an internal chamber and first divider wall (54) for separating the internal chamber into at least two sections (56,58). A carrier framework (60) is removably mounted on the mold box (42) and includes a peripheral seal for perfecting a seal between the mold box (42) and the powder box (52) when the same are connected thereto. A second divider wall (64) is connectable to the first divider wall (54) separating the inner mold surface into two chambers continuous with the two sections of the powder box (52). The carrier framework (60) further includes a mold surface seal (66) for perfecting a seal between the second divider wall (64) and mold surface (48).
