Abstract: The recovery of materials from viscous bodies of petroleum residue and asphalt deposits which contain substantial quantities of the deposits by the use of an induced thermal gradient in a region of such a viscous body in which there is located a screw-like pump.This is effected by a process and apparatus that utilizes a thermal gradient about a archimedian screw-type pump in the pit or pond where its inlet is proximate of the surface of the pit or pond. The thermal gradient about the pump concentrates less viscous components at the vicinity of the inlet and a positive pressure is applied to assure a flow of residue towards the inlet allowing the lower viscosity materials to be captured and pumped from the pit or pond to a shore facility.

Abstract: A molded plastic cosmetic contact lens made in a repetitive manner comprising a cosmetic pattern of clustered networks of interconnected thin colored lines radiating from and about the periphery of the pupil portion in a direction inclined towards and in contact with the periphery of the iris portion and residing within the iris portion. The lens can be made by molding in a manner that the cosmetic pattern becomes part of the body of the lens.

Abstract: A process for the manufacture of a molded contact lens containing a transparent central visual region circumscribed by a colored iris portion which comprisesa. coating a colored liquid which is either curable or thermoplastic in a mold for making a contact lens onto a surface thereof where the iris portion of the lens is formed to produce a colored film thereon which film contains a surface exposed to the interior of the mold and a surface in contact with the mold,b. charging the mold with the resin used to form the body of the lens while maintaining the colored film in the iris portion and configuring the resin about the colored film whereby the surface of the film becomes integral with the body of the lens and the surface of the film becomes part of the outer surface of the lens when the molded lens is removed from the mold.

Abstract: The invention is directed to the thermal mobilization of black oil residues by direct and/or indirect heating whereby the mobilized residues are then removed from the tank by a localized negative pressure means. The removed black oil residues are then treated to recover an oil which may be utilized alone or combined with other petroleum products.

Abstract: A reproducibly-made, wholly spuncast, non-truncated ballasted, compound surfaced soft contact lens and the method of making the same by spincasting a polymer forming monomer mixture.

Abstract: Herbal Extract Composition containing a Melissa species extract, an Avena species extract and a Tilia species extract; a Modified Herbal Extract Composition containing additional herbal extracts; a Beverage Concentrate containing the Modified Herbal Extract Composition; amd a beverage made from the Beverage Concentrate dissolved/dispersed in water.

Abstract: A tank accessing procedure is disclosed which allows for the replacement of a cover plate from a tank manway with an adapter having the capability of permitting access to the interior of the enclosure, without any appreciable spillage of the contents of the tank, even if the level of such tank contents is above the height of the manway. In particular, the method comprises first inserting a blanking plate between the cover plate and the manway flange, which blanking plate is then secured to the manway flange. The cover plate is then removed leaving the blanking plate as the sole means of retaining the tank contents in place. The adapter is then secured to the manway flange and the blanking plate is removed thereby completing the accessing operation.

Abstract: A water resistant, non-gummy, hygroscopic, flexible and pliable thin film containing a combination of a sunscreening agent and a 2-hydroxyethyl methacrylate homopolymer deposited on an epidermal surface, a stable emulsion from which the film can be made and a special process for the manufacture of the stable emulsion. The topical application of stable emulsions from which a water resistant, non-gummy, hygroscopic, flexible and pliable thin film of 2-hydroxyethyl methacrylate homopolymer in combination with a sunscreening agent is deposited on an epidermal surface. Special solvent combinations and emulsification techniques are described.
