Abstract: The invention pertains to an improved method, a lapping tool head (82) and a lens polishing apparatus for carrying out the method, for polishing ophthalmic lenses (26). The apparatus has a lapping tool head (82), a flexible membrane (134) covering a lapping portion of the tool head (82), and pump and nozzle for pumping abrasive slurry over the lapping tool head. The new method comprises the conventional step of imparting an oscillatory movement to the lapping tool head (82) and contacting the lens surface with the lapping portion of the lapping tool head while an abrasive slurry is pumped over the lapping tool head (82). The improvement comprises the additional step of periodically undulating the membrane (134) for imparting a wave in that membrane such that the abrasive slurry can flow between the membrane and the lens surface. The lapping slurry is efficiently moved over the entire surface of the lens for improving the quality of the lenses (26) polished by this process.

Abstract: A system for dispensing liquid paint components from their original containers into a paint receptacle according to a paint formula to form a liquid paint mixture. The dispensing system comprises a dispensing apparatus for dispensing the liquid paint component from its original container, and an apparatus for controlling the dispensing apparatus. The dispensing apparatus includes a mechanism for releasably receiving the original container of the liquid paint component, and a mechanism for dispensing the liquid paint component from its original container into the paint receptacle. The control apparatus includes a weigh cell and a control module coupled to the weigh cell and the dispensing mechanism. The weigh cell supports the paint receptacle to determine the weight of the liquid paint component dispensed into the paint receptacle.

Abstract: The present invention provides a method of improving the pigmentation of fish flesh. Specifically, this is brought about through feeding the fish with both pigment and cholesterol, which are generally combined into a foodstuff. This addition of the pigments in the diet which results in a change in flesh colour, blood pigment levels and flesh pigment levels of the fish. Further, the uptake of pigment into the plasma and flesh is shown to be optimal when the feed contains a cholesterol level of between 1 and 3 percent. Such a method of enhancing the uptake of pigment by fish can be used on Atlantic salmon, rainbow trout, other salmonids, tropical fish and any other fish species where the pigment colour of either the flesh or skin is important.
