Abstract: ABSTRACT OF THE DISCLOSURE     Incremental recovery of bitumen from the waste water streams of a hot water process for the extraction of bitumen from the tar sands is effected by directing the waste water down an inclined conduit to achieve gravity separation of the tailings stream constituents.  The bitumen rises to the top and is contained by a baffle near the downstream end of the conduit such that it can be withdrawn and processed into synthetic crude oil.  A tails weir at the downstream end of the conduit regulates the level of the remaining water and mineral which discharges over the tails weir enroute to a tailings pond.

Abstract: ABSTRACT OF THE DISCLOSURE         A test control circuit includes a channel selector circuit and input and output buffers, which cooperate with input/output buses and respective latches of the multichannel apparatus, to allow an operator to select one or more input buses, and one or more output buses, of a respective channel or channels of the multichannel apparatus. Thus the circuit allows selectively applying an input test signal to one or more channels via the front of the apparatus, while selective-ly monitoring the resulting output signal from the channel or channels also via the front of the apparatus.  An exemplary purpose of the test control system is to facilitate the channel alignment and head azimuth adjustment of, for example, a multichannel audio tape recorder.

Abstract: SLURRY DECAFFEINATION                           ABSTRACT      The object of the invention is to provide an improved method for removing caffeine from aqueous solutions such as coffee and tea extracts.     Decaffeination with water-immiscible fatty materials is impractical because the ratio of fatty material to aqueous caffeine solution will typically be about 20:1.  Non-solvent systems employing solid adsorbents have not been commercially practical because they are either too non-selective or too expensive.     The process disclosed herein decaffeinates an aqueous caffeine solution by contacting it with a slurry comprising a solid caffeine adsorbent and a water-immiscible, caffeine-specific solvent.  The caffeine is selectively extracted from the aqueous solution, leaving the solubles necessary for a good tasting beverage, and then removed from solution by the solid adsorbent.  Because the solvent is selective, the adsorbent does not have to be.  And, because the adsorbent continuously maintains a low concentration of caffeine in the solvent, much lower solvent to aqueous solution ratios can be employed, preferably less than 5:1.
