Abstract: An on-line sampling and analysis system and method in which a sampling line inlet pipe receives a continuous flow of a suspension or a slurry having particulates, such as grains, seed or phosphate rock, for rapid analysis of the contents therein in a flowing stream. A sample presentation area such as a window is positioned below the flow of the suspension or slurry in an assembly allowing for the depositing of a sample of solid content from the suspension or slurry which is collected for viewing by a computer controlled video camera. The camera is provided for imaging the sample of the solid content collected at the sample presentation area, and a personal computer analyzes images provided by the camera to characterize the content of the fluid media.

Abstract: Designs for basecurves are disclosed which are designed to promote adhesion of an excess polymer HEMA ring to the basecurve during a demolding operation such that the excess polymer HEMA ring is removed along with the basecurve during the demolding operation. The basecurve mold designs promote and maintain adhesion of an excess polymer HEMA ring to the basecurve in a process for molding cast contact lenses in mold assemblies, each comprising a frontcurve and a spaced basecurve, and wherein a molded lens is formed therebetween. In an embodiment of the invention, the annular area of the basecurve mold can be formed with an annular step which includes projecting teeth positioned therearound which project into the excess polymer HEMA ring.
