Abstract: A process for forming a plastic article, such as a container, involves heating at least one or more layers individually to temperatures below the melting point, immediately stacking two or more layers while retaining the peripheral portion of the layers and immediately forming the stacked layers into a plastic article which is then allowed to cool. Alternatively after stacking the layers, the stacked layers are immediately forged into a preform in a heated and lubricated mold and immediately thermoformed into a plastic article, which is then allowed to cool. The layers may be diverse (i.e. material, shape, molecular weight, additives, etc.) or similar and stacked so as to provide a layered angular orientation.

Abstract: A method for making contoured covers for vehicle seats is disclosed. A cover member is attached to a foam sheet which has an adhesive layer covering the face opposite from the cover member. The adhesive layer is in turn covered with a backing material. Portions of the cover member are pressed into the foam sheet, contacting the adhesive. The adhesive bonds the cover member to the backing material forming the contours in the cover. Alternatively the adhesive layer may be omitted if a thermally sensitive backing material is used. In this case the portion of backing material pressed into contact with the cover is partially melted to bond the backing material to the cover.

Abstract: A plunger for a check valve and a method for constructing such a plunger. The preferred plunger has a shell of P.T.F.E. sealingly secured to a rigid, metal disk. The cavity betwen the shell and the disk is filled with a silicone rubber material which, together with the shell, provides a resiliency that enables the shell to conform to irregularities in its mating valve seat even when the seating pressure is low.

Abstract: A tennis-ball is made by covering a spherical core with twelve substantially identical pentagonally-shaped pieces of a cover material. Before the pentagonally-shaped pieces are attached to the core, they are covered on their outermost surface by a removable layer of adhesive-impermeable barrier material (e.g. tissue paper). The barrier material restrains the movement of the pentagonally-shaped pieces when applied to the spherical core, so that a narrow uniform seam is obtained. When all twelve cover pieces are correctly positioned on the core, the barrier material is removed and the assembly subjected to a random rolling action to "finish" the ball.

Abstract: A pair of sheets (46 and 48) are held by vacuum on a pair of spaced drums (30 and 32). A rigid board (51) is moved between the drums (30 and 32) whereafter the drums are moved toward each other to adhesively attach leading edges of the sheets (46 and 48) to opposite sides of a leading edge (50) of the rigid board. As the board (51) is moved away from the drums (30 and 32), the drums are indexed to release successive sections of the sheets (46 and 48) which extends the sheets in a wrinkle-free condition. As the board (51) continues to be moved away from the drums (30 and 32), the successive sections of the sheets (46 and 48) are maintained spacially from the board and in the wrinkle-free condition by various facilities such as a vacuum shoe (52), a shelf (53), a vacuum tensioning tube (56) and vacuum bars (57 and 58). Eventually, the wrinkle-free successive sections of the sheets (46 and 48) are brought into engagement with the board (51) and attached thereto by laminating rollers (59 and 60).

Abstract: A safety shield for containing and deflecting a fluid leaking from a flanged pipe coupling in the form of an arcuate strip of transparent fluoropolymer. The strip has a flange along each circumferential edge which is integral with the strip and extends radially inwardly thereof. The strip is of sufficient length to encase the circumference of the pipe coupling flange to which it is applied with the opposing ends overlapping and fastened together. The flanges closely engage the radial surfaces of the coupling flanges. The safety shield is obtained by heat-shrinking a heat-shrinkable tube of fluoropolymer while restricting radial shrinkage thereof except the marginal edge portions which become the flanges.

Abstract: A method for making a cervical contraceptive diaphragm provides for fabricating the entire dome assembly in a separate step, thereafter inserting a toroidal spring within a toroidal chamber pre-formed in a flange affixed to the base of the dome structure, the spring being sealed in by a separate sealing process preferably by a thin filament of vulcanizable rubber laid along the flange away from the spring. Local heating of the filament to cure it and seal the flange about the spring provides for a spring not interpenetrated by liquid elastomer during the curing process, resulting in a free floating spring. The method allows the fabrication of structures employing relatively stiff springs of limited radial compliance, so that the diaphragm may be removed from the first forming mold with minimum loss arising from tearing of the lip.

Abstract: The invention relates to improvements in machines employed for enclosing battery plates within a pouch of sheet material. The sheet is positioned so that the center of its length is disposed between the side of a fixture adapted to receive adjacent thereto the bottom edge of a battery plate and a slot and the sheet is enfolded around the battery plate by moving the fixture plate combination horizontally into and through the slot. As the wrapped bottom edge of the plate emerges from the slot, grasping means are engaged with the wrapped end of the battery plate and hold the plastic sheet tightly so as to prevent any displacement relative to the enclosed battery plate. The fixture is then withdrawn from the enfolding sheet. The overlapping lateral edges of the sheet are then sealed and the battery plate is dropped into an inclined position on an intermittently moving horizontal conveyor to produce a horizontal stack of wrapped plates.
