Abstract: Thermal treatment of heavy petroleum resid in the presence of moderate amounts of light aromatics or paraffins produces more liquid product at the expense of gas and coke than when treated alone under identical conditions.

Abstract: A recirculatory lubrication system for applying a film of lubricant to an open gear set having a pinion gear and a bull gear in meshing engagement with the pinion gear, the open gear set at least substantially enclosed by a gear set cover having a lower portion for collecting lubricant therein.

Abstract: A synthetic oil for the cooking and frying of foods which includes a hydrogenated oligomer of an alpha olefin having to 20 carbon atoms. The synthetic oil of the present invention is not readily digestible in mammals and provides a non-toxic, safe low-caloric, low-metabolic fat content substitute for vegetable oils.

Abstract: Non-carcinogenic asphalts and asphalt blending stocks are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the asphalt or asphalt blending stock and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic asphalts and asphalt blending stocks are then processed utilizing the conditions so established.

Abstract: A laundry basket and a handle assembly therefor are disclosed. The laundry basket includes a walled container having a peripheral rim about a substantial portion thereof, a pair of opposing hand openings adjacent the peripheral rim, and a pair of handle members extending, respectively, about the rim and through the hand openings, each of the handle members including a bottom portion positioned below the rim, the bottom portion defining an upper boundary of one of the hand openings and a top portion, the top portion being connected to the bottom portion, wherein one of the top or bottom portions of each of the handle members is integral to the peripheral rim. Each portion of the handle members preferably includes a curved exterior surface to facilitate the lifting and carrying of the basket.

Abstract: An apparatus for repairing a well completion having a gravel-packed annulus formed by a liner and a well casing, the annulus having at least one region within the gravel pack which is devoid of gravel.

Abstract: A domed container. The container includes a receptacle and dome cover therefore having locking means for releasably locking the cover to the receptacle. The receptacle includes a bottom wall having a top surface delimited by an upstanding rib and terminating in an outwardly extending resilient rim.

Abstract: A pH tolerant aqueous gel-forming composition for placement within a subterranean formation. The composition includes water, a viscosifying amount of a heteropolysaccharide prepared by growing Xanthomonas campestris NCIB 11854 in an aqueous nutrient medium by aerobic fermentation and recovering the heteropolysaccharide, and a crosslinking agent for the heteropolysaccharide in an amount sufficient to cause gelation of the aqueous solution of the Xanthomonas compestris NCIB 11854 heteropolysaccharide. Also described is a two-stage gel-forming composition for use in controlling the profile of a subterranean formation.

Abstract: An apparatus for automatically counting and stacking articles, comprising: a conveyor for conveying a plurality of articles to at least one fixed stack position; and at least one stacking mechanism, the stacking mechanism comprising: an article carriage peripherally disposed about the fixed stack position, the carriage extending substantially perpendicular to the fixed stack position, wherein the carriage has at least one stacking dog for engaging and suspending articles above the fixed stack position; an article pusher located below the fixed stack position, the pusher capable of projecting an article positioned at the fixed stack position at a distance effective to engage the article with the stacking dogs and suspend the article therefrom; an article pullback mechanism positioned upstream of the article pusher for retaining subsequently conveyed articles in a queued relation; and a counter for counting articles suspended above the fixed stack position.

Abstract: An opaque, biaxially oriented multi-layer polymeric film structure of reduced surface coefficient of friction.
