  • Patent number: 5016297
    Abstract: A sink assembly is disclosed that has a separate rim and basin made of different materials. The basin has a flange surrounding a bowl that is exposed under the rim to form an accessible ledge. A glass-filled polyester resin is injected into a mold adjacent the underside of the rim member and the flange. The polyester resin bonds with the rim member and prevents the basin from moving relative to the rim member.

  • Patent number: 4626454
    Abstract: A decorative fitting having an internal layer as well as a method of fabricating it are disclosed. Preferably, the color layer is a very thin color wall dimensioned so that when it is viewed at one angle it gives the appearance of being a solid wall, yet when it is viewed at another angle it is substantially transparent. To make the color wall, one preferably forms a frame on a first substantially transparent panel such that the frame projects out from the first panel surface. One then abuts a second substantially transparent panel against the frame so as to form a color material insert cavity point, one injects a flowable colored material/adhesive mixture into the cavity and permits the colored adhesive to harden and bind the panel walls together. Thereafter, one cuts the transparent panels into a multiplicity of handle components by cutting the walls along lines partially transverse to the color layer. This forms multiple handle components which are a sandwich of the walls with the color layer in between.
