Abstract: The invention described herein includes a latrine pan and collector system for use in an offset pit latrine. The system permits use of a latrine pan having a flapper in an offset leach pit context, and eliminated the necessity of large scale installation of a concrete collection box, which can collect unsanitary debris. The system of the invention includes (1) a pour-flush latrine pan and (2) a collector.

Abstract: An elastomeric seal used in molding articles is disclosed. The seal has a first lateral cross-sectional dimension larger than the opening of a seal groove and at least a second lateral cross-sectional extending beyond the opening of a seal groove which is smaller than the lateral cross-sectional dimension at the opening of the seal groove. The elastomeric seal is releasably retained in the seal groove and provides an improved molding cavity for molding articles such as sanitary fixtures, i.e., tubs, whirlpools, spas, etc. Also disclosed, is a molding apparatus including the elastomeric seals useful in molding sanitary fixtures.

Abstract: An adjustable sealing system for use in a molding apparatus is disclosed. The molding apparatus is used for applying a coating of polymeric material to the surface of a shell. The molding apparatus includes a molding surface and a seal groove adapted for retaining a seal. The molding apparatus is capable of receiving a shell and forming a molding cavity between a surface of a shell and the molding surface. The seal establishes sealed contact between the shell and the molding surface when the molding apparatus is closed. The adjustable sealing system includes a seal for insertion and retention in a seal groove of the molding apparatus, so that a portion of the seal extends from the seal groove to a selected height when the molding apparatus is open. A seal height adjustment means is disposed under the seal in the seal groove. The seal height adjustment means is capable of adjusting the height of the seal above the seal groove to correspond to a particular contour of a shell being molded.

Abstract: An elastomeric mold seal for use in a molding apparatus having first and second molding members. The first molding member includes a seal groove therein. The molding apparatus is adapted to receive an article for molding one side thereof having an upstanding rim including a lip, a vertical wall and horizontal wall. The mold seal is formed from an elastomeric material having an essentially L-shaped cross-section including an enlarged head sized to be retained in said seal groove and a leg having an end depending therefrom. The seal includes a recessed portion including an essentially horizontal ledge and an essentially vertical surface. The ledge engages the lip of the rim, the essentially vertical surface engages the vertical wall of the rim and the end of the leg engages the horizontal wall of the rim when the article is being molded in the molding apparatus.

Abstract: A manufacturing insert for a molding press having an upper movable platen adapted to support a male mold member and a fixed lower platen adapted to support a female mold member. The molding press includes a mix head system and a hydraulic ejector system supported below the fixed lower platen. The manufacturing insert includes a table having a platen surface with legs depending downwardly therefrom, the legs being removably securable to the fixed lower platen of the molding press. The platen surface includes an enlarged opening therethrough. A mix head support system is supported below the platen surface intermediate the legs of the table. The mix head support system includes a mix head support for supporting a mix head and a slide system for permitting three dimensional movement of the mix head support to permit movement of the mix head from a first position where the mix head extends through the enlarged opening in the platen surface and to a second position where the mix head is beyond the upper platen.

Abstract: A composite structure, e.g. a plastic-backed enameled carbon steel or stainless steel finish product has high impact, delamination and thermal shock resistance. The composite structure is formed from a carbon steel or stainless steel shell having a finish side which may have a polished, ceramic, enameled, polymeric or metallic coating. On the other, non-finish side of the shell a layer of reinforced plastic is bonded directly to the steel or stainless steel shell using silane to form a laminated structure. The finish layer is resistant to deformation and delamination when subjected to relatively high impact applied directly to the finish or to the plastic layer surface, or when the composite structure is subjected to a sudden temperature change.
