Abstract: A method and apparatus for making a plastic lens and a plastic lens made thereby are provided, the method comprising the steps of disposing a lens forming material comprising a liquid monomer and a photosensitive initiator into a mold cavity defined in part between a pair of spaced apart mold members each having a lens forming surface facing the cavity and an outer opposed surface, directing rays of ultraviolet light from a source thereof against the outer surface of at least one of the mold members so as to pass therethrough to act on the lens forming material in the cavity to produce the lens therefrom, and forming the outer surface of the one mold member with structure to cause the ultraviolet light directed thereagainst to be substantially evenly distributed throughout the lens forming material in the cavity in order to tend to prevent optical distortions in the lens being formed therefrom.

Abstract: A method and apparatus for producing a product which stimulates skin respiration and product produced thereby are provided wherein the method comprises the steps of mixing bakers yeast and alcohol in an extractor to produce a slurry of solids and liquid, heating the slurry to a predetermined temperature to produce a heated slurry, holding the heated slurry at the predetermined temperature for a predetermined time, passing the heated slurry through a filter to remove the solids and produce a filtered liquid, placing the filtered liquid in a sterile vacuum still and boiling the filtered liquid in said vacuum still to drive off a substantial percentage of the liquid therein and produce the product, and then further filtering the product in a closed pressure filtering system followed by filtering of the further filtered product through a sterile filter.
