Abstract: "IMPROVEMENT PROCESS FOR SECONDARY RECOVERY OF BITUMEN   IN HOT WATER EXTRACTION OF TAR SAND"    ABSTRACT OF THE DISCLOSURE It has been found that tank-type air flotation cells. are more efficient, when treating hot water process middlings containing in excess of about 3% bitumen, than trough-type air flotation cells.  Also, it has been found that the trough-type cells are more efficient than the tank-type cells when treating middlings containing less than about 3% bitumen.  Thus a secondary recovery circuit is proposed wherein the middlings are first treated in one or more tank-type cells in series and the underflow from the last tank-type cell is treated in one or more banks of trough-type cells.

Abstract: ABSTRACT OF THE DISCLOSURE        Heretofore, the only practical way known to decrease the viscosity of an ionically thickened tetrafluoroethylene polymer dispersion has been by diluting it with water. This decreases the solids level, which can have an undesirable effect on subsequent processing. It has now been discovered that if the tetrafluoroethylene polymer dispersion contains a sodium phosphate in which the ratio of Na2O to P2O5 is between 1:1 and 3:1, the viscosity of the dispersion can be decreased by adding selected inorganic electroytes.

Abstract: 1.11.1978                    1                   PHN 9047 ABSTRACT :       Optical disc player.     An optical disc player comprises a read objective on a carriage which is translated to and fro with the aid of a drive unit with an electric motor by cooperation of a drive pinion and a gear rack, so that the read objective travels between a minimum diameter and a maximum diameter of the disc to be read between which the information is contained. A pinion and a gear wheel of the drive unit cooperate with each other without play, in that the pinion is mounted on a pivoting member which is resiliently loaded, so that the pinion and the gear wheel are in resilient engagement with each other. During work on the optical disc player the pivoting member can be pivoted away by hand, so that the teeth of the pinion and the gear wheel are disengaged from each other so that a quick, practically unhampered translational movement of the carriage is possible.

Abstract: Abstract The volumetric output of fuel injectors is rapidly and accurately measured by accumulating in first and second counters  respectively,  a  count  of  pulses  generated  as  a function of the strokes made by the injector, and a count of pulses generated by an optical encoder attached to the piston of a positive displacement flow meter through which the output of the injector is directed. When the first counter reaches a count representative of a preset number of injector strokes, the accumulated count in the second counter representative of injector output for the preset number of strokes is stored and displayed continuously while the counters are reset and the test cycle is automatically repeated. The direction of movement of the reciprocating piston of the positive displacement flow meter is automatically reversed by the control system as either end of  travel is reached through coordinated operation of a pair  of  solenoid  valves.  The  control  system inhibits  both counters during piston reversal and synchronizes resumption of counting to eliminate errors due to transients. Because of the high accuracy of the system, accurate measurements of injector volumetric flow are obtained in 50 injector strokes rather than the conventional 1000 strokes or even the 100 strokes of some newer systems.
