Abstract: IRRIGATION AND SUCTION HANDPIECE                 ABSTRACT OF THE DISCLOSURE    An irrigation-suction handpiece assembly, for dental and surgical use at an operating site, includes a handle containing longitudinally extending, side-by-side suction and irrigant passageways respectively connectible to a source of subatmospheric pressure (i.e., a vacuum source) and an irrigant fluid source.  An irrigant valve is actu-able for alternately opening and blocking flow of irri-gant from the irrigant source through the irrigant passageway.  An air pressure conduit includes a third passageway in the handle and connectible to an air pres-sure source which is not atmospheric pressure and not influenced by pressure changes in the suction passageway. This air pressure source is either a further subatmo-spheric pressure source or a compressed gas source.  The third passageway has a relief opening in the handle selectively openable or closable by the hand of the oper-ator for effecting a change in the pressure within the third passageway.  The irrigant valve has a control input coupled with the air pressure conduit and third passage-way and responsive to such change in air pressure therein for shifting between its open and blocking states to thereby control the flow of irrigant fluid to the oper-ating site.

Abstract: ABSTRACT     An improved process for aqueous electrowinning of metals, using methanol (or another soluble fuel) added to the electrolyte, a catalytically active platinum mesh or platinum-plated titanium anode and periodic current interruption or reversal, in order to maintain a low anodic potential, and hence, a cell voltage and energy consumption lower than in conventional processes.  Examples illustrate the electrowinning of zinc and copper from sulfuric acid-sulfate electrolytes, but the process applies to other metals.  Also disclosed is the use of an ion-exchange membrane in combination with the above features, in order to decrease the loss of fuel from the anolyte and to minimize the effect at the anode of impurities present in the catholyte.

Abstract: Abstract A circuit for reducing low frequency noise in a direct current biased superconducting quantum interference device.          A squarewave bias signal having no dc component is used to bias the two junctions of the dc SQUID.  At the same time, the magnetic flux in the SQUID is modulated to heterodyne the input signals up to some convenient frequency where they may be amplified without concern for drift.  Final demodulation automatically adjusts for the fact that the relative phase is reversed each time the squarewave bias changes polarity states.

Abstract: ABSTRACT OF THE DISCLOSURE          Persistent crude petroleum-water emulsions from oil sands, heavy oil or conventional oil wells are mixed with an aqueous  mixture of coal particles so that the mixture has a suspension density in the range 1 to 50 weight % solids.   The coal particles have a particle size in the range 5 to 100 µm so that occluded hydrophilic, inorganic solids are separable from a substantial portion of the hydrophobic, carbonaceous substances of the coal.  The mixing of the crude petroleum with the  aqueous suspension of coal particles is continued until agglomerates are formed comprising carbonaceous substances of the crude petroleum and the coal thereby interdependantly dis-sociating inorganic, hydrophilic components and water from the crude petroleum and the coal.  The agglomerates are sepa-rated from the dissociated, inorganic, hydrophilic components and then volatile components of the agglomerates are thermally or otherwise extracted  from the remainder.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and process for casting a material into a desired shape.  The apparatus and process comprise the structure and steps for electromagnetically forming the material in molten form into the desired shape.  An electromagnetic forming device applied an electromagnetic field to the molten material.  This magnetic field defines a containment zone for the molten material.  A sump  of molten material is opera-tively associated with the forming structure for delivery of molten material to the forming structure. A device is provided for withdrawing the casting from the forming device at a desired withdrawal rate. Another device replenishes the sump of molten material at a replenishing rate as the casting is formed.  The improvement comprises a control device for maintaining the hydrostatic pressure exerted by the molten material in the containment zone at a substantially constant desired level. The control device includes a first structure for providing a substantially constant material volume balance by maintaining the ratio of the withdrawal rate to the replenishing rate substantially constant when the hydrostatic pressure in the contain-ment zone varies less than a desired percentage from the desired level.  A second device senses variations in the level of the hydrostatic pressure of the molten material in the containment zone.  A third device is responsive to the second device for providing a material volume imbalance by varying the ratio of the control rate to the replenishing rate when the hydro-static pressure level of molten material varies more than said desired percentage from the desired level until the hydrostatic pressure of molten material in the containment zone returns to the desired level.
