Abstract: PREPARATION OF BITUMEN FROTHS AND EMULSIONS                     FOR SEPARATION     ABSTRACT OF THE INVENTION     An oil and water mixture containing a dispersed phase and a continuous phase is passed for treatment through a rotating horizontal tumbler containing free bodies and a hydrocarbon diluent for the purpose of facilitating subse-quent separation of the phases of the mixture.  The free bodies tumbling with the mixture in the drum have affinity for the dispersed phase particles, and the hydrocarbon diluent reduces the viscosity of the oil phase thereby caus-ing an increase in the particle size of the dispersed phase of the mixture.  Some mixtures that may be treated include effluent streams from a hot-water oil sands extraction plant, oil and water emulsions from processes that use enhanced oil well recovery, bitumen emulsions, bitumen froth and shale oil emulsions.

Abstract: EASILY ASSEMBLABLE TRANSVERSE MAGNETIC PRINTING HEAD                 Abstract of the Disclosure An easily assemblable transverse magnetic printing head and method for making same are disclosed for use in a coincident current, matrix-driven, transverse printing head.  In accordance with one embodiment of the present invention, digit lines pass through a recording gap in mirror image fashion as between adjacent word groupings.  Similarly, the word line patterns are arranged on a printed circuit board in a zig-zag fashion.  A feature common to both the word and digit line printed circuits, however, is the presence of a small expanse of circuit wiring unsupported by printed circuit substrate material through which a high permeability magnetic comb structure is inserted to form required recording gaps.          The coincident current scheme is retained by driving the digit lines from alternating directions.  The arrangement of the digit lines in the present invention permits the use of a planar printed circuit with no crossovers and therefore a circuit which is easily fabricated in a flexible, printed circuit design.

Abstract: Abstract The device includes a main flow control valve and associated packings designed for effective operation under extreme conditions associated with the pumping of high vis-cosity asphaltic crude wherein the formation includes toxic gases, and where the formation is produced using steam flooding techniques.  The main valve seat and the associated valve closure, consisting of a reciprocating ram and packing plug, are coaxial with the pump polished rod.  The valve seat includes tapered walls defining a shoulder which partially confronts the ram plug; and the ram plug is formed of a compressible material formed to the shape of the valve seat.   The packing plug is retained on the end of the ram by axial tie rods and a retaining ring, which ring may engage the valve seat shoulder to effect axial compression of the packing plug between the retaining ring and ram face, and consequent radial expansion into sealing engagement.  The ram is reciprocated axially, either manually or hydraulically relative to the ram body; and a packing gland, suitable to seal against toxic gases, is provided between the ram and valve body.  A rod packing, at the upper end of the ram, includes a primary adjustable packing gland for effective sealing between the ram and the reciprocating polished rod; and may also include a positive shutdown gland for positive sealing at the polished rod in the event of the failure of the primary gland.  The positive shutdown is designed for hydraulic operation, to enable automatic operation in response to detec-tion of a gas leak at the primary gland.

Abstract: Abstract of the Disclosure The laminations of a laminated stator of a slowly running electrical machine having a high number of poles are composed of grain-oriented sheets, each of which has a preferential magnetic direction that extends substantially longitudinally along the teeth of that sheet.  This permits the excitation current to be reduced, and, as a result, the air gap of the machine is enlarged so that, on the whole, approximately the same excitation is required as for a laminated stator in which the laminations consist of normal, non-oriented sheets. As a result, the mechanical stability of the machine is increased.  The invention is especially useful in asynchronous bulb turbine sets.
