Abstract: ABSTRACT          .        In the extraction of bitumen oils from oil sands, the raw material is first slurried with a stream of hot water under conditions promoting the release of the bitumen oils without disintegration of clay in the raw material;  the water to raw material is at least 1:1 by weight.  The slurry is separated into an oil-rich component, a solids component, and a middlings component containing essentially water and fines with only minor proportions of oil and solids.  The middlings component, after removal of the contained fines and the solids is recycled as a part of the slurrying water.

Abstract: ABSTRACT OF THE DISCLOSURE           A drive circuit for a latching relay wherein a flip-flop responds to a first input signal and to a second input signal entered into the drive circuit and provides alternately a first control signal and an inverse control signal as an output corresponding to a change in the flip-flop's stable condition.  A timer is connected to the output of the flip-flop for receiving the first control signal and the inverse control signal and a semiconductor switching circuit is connected to the timer with the timer controlling the semiconductor switching circuit for a constant time period, which produces a control signal in response to a first input signal and an inverse control signal to said control signal in response to a second input signal.  The semiconductor switching circuit is adapted for connection to the latching relay with the latching relay receiving from the semiconductor switching circuit a time limit output such that even if said first and second input signals are given to the drive circuit in an extremely short time after said timer responds to said control signal coming from the flip-flop, a sufficient time period is provided for said time limit output in order to energize and keep on said semiconductor switching circuit during the time period of current sufficient for said latching relay and where even when the output of said control signal is cut off between the first input signal and the second input signal, the latching relay keeps its existing relay working condition.  The circuit of the invention is fully compatible with computers and integrated circuits which cannot use the large capacity condensers generally required by prior art circuits for driving latching relays.

Two co-linear transverse pins 12 are mounted at the top of the portion 10, and a central recess 18 is formed in the profiled portion 10. An end member 22 having an aperture 24 therein is located at the base of the recess 18.  A latch bar 34 and an operating cylinder 36 are mounted on the assembly 4, and are dimensioned to fit in the recess 18.      In operation, the assembly 4 is tilted forwardly and advanced until the lifting pins 12 enter the forks 32. The assembly 4 is then tilted backwards and edged forwardly until the cylinder 36 and the latch bar 34 enter the recess 18.  The cylinder 36 is then operated to advance the latch bar 34 into the aperture 24 to couple together the bucket 2 and the assembly 4.      To detach the bucket 2 the cylinder 36 is operated to retract the latch bar 34 from the aperture 24   The assembly 4 is tilted until the lower face of the bucket 2 swings out parallel to the ground, and the bucket 2 is then lowered until it rests on the ground.  The assembly 4 is tilted forwardly and is reversed to withdraw the forks 32 from the pins 12.

Abstract: ABSTRACT OF THE DISCLOSURE:     The present invention is concerned with foams of phenolic resol resins which discolour less quickly than the hitherto known phenolic resin foams.  In addition, dyed foams do not darken so quickly with the additive according to the invention.  The foams according to the invention contain as stabilizers salts of phosphinic or phosphonic acid, like for example the primary alkali phosphites or the alkali phosphinates.      The stabilizers protect the foams against the effects of light and/or air and/or heat;  they may be employed in amounts of between 0.1 and 5 weight %.  The present invention also provides a process for the production of these foams.  A preferred procedure involves premixing the stabilizers with a foamable phenolic resol resin and then mixing the mixture obtained with the remaining substances necessary for completion of a foam and then foaming the combined mixture up in known manner.

Abstract: WARP KNITTED SELF-LINED FABRICS    WITH WOVEN APPEARANCE           ABSTRACT     A self-lining decorative fabric is especially adapted for use as a drapery, and simulates the appearance of a woven fabric. The fabric includes a non-woven or other substrate fabric with weft yarns disposed on a first face of the substrate and warp yarns disposed on the first face of the substrate laying on top of the weft yarn. The warp yarns extend in lines substantially perpendicular to the weft yarns, although they may have curvilinear or zig-zag paths while extending in such lines. Stitching thread holds the warp and weft yarns in place on the substrate first face, stitch portions of the stitching thread passing over the warp and weft yarn, and loops of the stitching thread being disposed in contact with the substrate second face, opposite the first face. The stitching thread may be the same color as the substrate while the majority of the warp and weft yarns are of a different color, and at least some of the warp and weft yarns preferably are effect yarns. When used as a drapery material, a foam backing or other coating may be applied adhering to the substrate second face.

Abstract: METHOD AND APPARATUS FOR CONTROLLING A PRINTER    ABSTRACT OF THE DISCLOSURE         A method and apparatus for controlling a printer of the type having plural print heads for printing indicia of different colors by transferring a color dye from a dye medium to a record medium.  Each print head is supplied with an energizing signal for a time duration that determines the relative intensity of an indicium printed thereby.  Image signals which represent the intensities of the indicia to be printed by corresponding print heads are compared, in a predetermined sequence, to a reference signal whose level changes with time.  As each image signal is compared an energizing signal is produced for a duration that is determined by the value of that image signal with respect to the level of the reference signal.  The durations of the energizing signals are varied as a function of the print characteristics of the dye medium from which the indicia are printed.  Non-linearities in the relationship between the intensity of a color indicium printed from the dye medium and the duration of the energizing signal thus are compensated.

Abstract: ABSTRACT OF THE DISCLOSURE         An ignition analyzer apparatus tests the condition of the ignition coil of an internal combustion engine.  A gating pulse is supplied to a test circuit immediately before the points are to open for a selected cylinder which causes the test circuit to provide a low resistance in parallel with the points when the points open.  This allows a reduced primary current to flow through the ignition coil and prevents the production of a voltage pulse large enough to fire the spark plug for the selected cylinder.  While the points are open and the test circuit is providing a low resistance path, the primary current flowing through the coil is measured.  The gating pulse ends approximately halfway between the "points open" time of the selected cylinder and the "points open" time of the next cylinder so that the rotor of the distributor is between distributor terminals.  When the gating pulse ends, the test circuit changes to a nonconductive state, and since the points have not yet closed, the primary current is interrupted and a high voltage secondary test signal is induced in the secondary of the ignition coil.          This test signal cannot, however, fire a spark plug since the rotor is in between distributor terminals, and since the reduced amplitude of the primary current prevents arc-over from the rotor to the distributor terminals.          The measured primary current and the measured high voltage secondary test signal are used to provide an indication of ignition coil condition.
