Abstract: A collapsible spacer for disposition between a form for a concrete foundation member and the underlying soil includes voids to allow the spacer to deform permanently and occupy a reduced volume when upheaving of the soil occurs. The spacer is fabricated from a material, such as expanded polystyrene foam, whose structural strength is not significantly altered by exposure to moisture. Embodiments of the spacer which are suited for use with forms for foundation beams and slabs are discussed.

Abstract: The specification discloses a system for producing and distributing index coded hangers to a plurality of locations, wherein the index indicia is correlated to the characteristics of the garment to be hung from the hanger at each of the plurality of locations. A unique hanger and index cap is disclosed, along with a method and means of making the same that is particularly adapted to high volume semi-automated operation. A device for assembling the index cap and hanger at the time the garment is hung is also disclosed.The system contemplates the localized production of the index caps for improved control of batch color and other characteristics, with remote molding and assembly of the hangers at said plurality of remote locations.

Abstract: A molded plastic garment hanger constituted from two materials which are fused and bonded to form a composite hanger. Also disclosed is a method and apparatus for the two-step or co-injection molding of plastic materials for the formation of the plastic garment hanger construction. The plastic garment hanger incorporates an insert consisting of a second plastic material adapted to have indicia and/or logo means molded therein, and which insert may be fused to the hanger structure so as to form a bond with the first plastic material constituting the basic garment hanger.

Abstract: A bat for the wheelhead of a potters wheel is formed entirely from plastic and has opposing flat faces, one of which is smooth and other of which is textured.

Abstract: A price chip support strip of simplified construction has positive engagement with guide and retention tracks of a strip support frame. Individual price chips are conveniently removed and inserted at the front of the price chip support strip. An effective light seal is assured by the structure.

Abstract: A first and a second element, the latter being insertable in the former, but prevented from being extracted due to operation of blocking means. Each of the said first and second elements is provided with cooperating members for engaging the article to be marked. The blocking means can be disengaged.

Abstract: Pricing modules of the type having precoiled numeric indicia tapes are slidably held in guide channels of a mounting trackway assembly. Additional guide channels in the trackway assembly receive customized alpha indicia strips forwardly of the pricing modules. Pricing module locator notches are provided in wall portions of the trackway assembly to interlock with spring locking elements on each pricing module to properly position each module along the mounting trackway assembly. Multiple sections of the mounting trackway assembly can be provided in interlocking engagement.

Abstract: An open channel gate valve in which the gate blade is slidably received in parallel grooves in a frame. The gate blade carries a sealing member of truncated V-shape, which engages a seat of truncated V-shape provided on the frame. Both the seat and sealing member are disposed in axially offset relation to the plane of the gate blade.
