Abstract: "METHOD AND APPARATUS FOR ON-LINE MONITORING OF              BITUMEN CONTENT IN TAR SAND"                        ABSTRACT OF THE DISCLOSURE       An improvement in the processing of bituminous sands is described, whereby the concentration of bitumen in tar sand feed is measured by infrared light reflected from the tar sand surface.  Near infrared is shone onto the surface of the incoming tar sand and reflected light is collected and passed through two parallel filters, one being a measuring filter having a wavelength range of 2180 to 2260 nm and the other being a reference filter having a wavelength range of 2270 to 2350 nm. The beams emerging from the filters are measured electronically and the resulting signals are separately integrated and amplified by electronic means.  The ratio of the amplified signals is used to provide a read-out signal responsive to the bitumen concentration.  The results may be used to adjust processing conditions in the extraction process to allow for the variations of bitumen in the feed.

Abstract: ABSTRACT       A linear drive arrangement comprises a prime mover which is capable of rotatably driving a screw threaded rod. A carriage is mounted on the rod and carries a plurality of bristles, for example in the form of a brush, which bristles contact the surface of the screw threaded rod.  Rotation of the rod by the prime mover causes the bristles to follow screw thread of the rod to drive the carriage along the rod.  The advantage of this is that no clutch mechanism is required as if force is applied to the carriage either to prevent it from moving along the rod or to push it along the, rod, the bristles will flex to ride over -the screw threaded surface of the rod.

Abstract: PRODUCING WELL STIMULATION METHOD -COMBINATION OF THERMAL AND SOLVENT          ABSTRACT OF THE DISCLOSURE           A method for the cyclic thermal stimulation of heavy oil adjacent producing wells to increase recovery of the oil produced therefrom by using an in-situ combustion process wherein oxygen or a fluid containing a minimum of about 75% by volume pure oxygen is injected into the well as the oxidizing medium, igniting the oil in the reservoir around the producing well so as to produce a combustion zone and to generate combustion gases consisting essen-tially of carbon dioxide and water in the form of steam, continuing injection of the oxygen until the combustion zone has propagated radially a distance of about 5 to 50 feet from the producing well, and thereafter recovering oil from the well.  After terminating combustion, the well may be shut in for a period of time to allow the carbon dioxide and heat generated to more effectively permeate the reservoir adjacent the well prior to being returned to production status.  The carbon dioxide dissolves in the oil reducing its viscosity along with the viscosity decrease resulting from the heat generated in the reservoir by combustion so that when the well is opened for production there is an improved flow of oil.   0570n

Abstract: ABSTRACT            A method for measuring the level of glucose in animal body fluids such as blood and urine, comprises contacting the body fluid with a glucose indicator comprising a reversible complex of a carbohydrate component, a binding macromolecular component, and an indicator element bound to one of the com-ponents, and maintaining the body fluid in contact with the indicator for a period of time sufficient to permit any glu-cose present in the body fluid to displace the carbohydrate component in the complex, and to thereby release the indicator element to signify the presence of glucose.  Preferably, the macromolecular component comprises one or more lectins; and the carbohydrate component may be one or more of the sugars for which testing is desired.            In one embodiment of the present invention, the indicator may comprise a dye or color-forming radical, associated with either the lectin or the carbohydrate, incorporated in a test strip or kit, for rapid, in vitro glucose level measurement.            Alternately, the indicator may be a glucose monitor comprising an electrode adapted for in vivo measurement of glucose con-centration, by implantation in registry with the body fluid system of the animal for which measurement is desired.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method of sealing the space between a socket and a spigot end of a pipe joint. Before the sealing surfaces are inserted one into the other a sealing ring is positioned in connection with one of the sealing surfaces, the sealing ring being thereby enclosed in or being thereby enclosed into a covering, which contains a lubricant.  The insertion of the sealing surfaces one in the other is facilitated either by the fact that the covering is broken so that the lubricant is made accessible at sur-faces of the joint sliding against each other and/or by the fact that a portion of the covering slides between the seal-ing ring and the sealing surface or the sealing surfaces.

Abstract: Abstract of the Disclosure An air atomizing nozzle assembly for electrostatic spray guns is disclosed.  The nozzle assembly is made of plastic parts and includes an air cap having a central bore which surrounds a fluid nozzle tip.  The nozzle has a nut formed on its forward end to facilitate threading of the rearward end of the nozzle tip into a threaded bore of the gun body.  Formed on the front part of the nozzle, either as a part of the nut or a cylindrical surface adjacent the nut, is an accurately machined surface engageable in press fit relationship with a mating accurately machined bore of the air cap.  These mating press fit surfaces center the bore of the air cap relative to the nozzle tip so as to leave an annular, evenly dimensioned air flow passage surrounding the nozzle tip and defined between the nozzle tip and the bore of the air cap.  The air cap is retained in a one-piece resilient retaining ring by snapping the air cap into an annular lip of the retaining ring.
