Abstract: METHOD FOR IMMOBILIZING CONTAMINANTS      IN PREVIOUSLY LEACHED ORES                         ABSTRACT          This invention relates to a process for reducing to environmentally acceptable levels the amount of soluble or mobile contaminants in formations that have been subjected to in situ leaching to recover mineral values therefrom.  The present process is also applicable to surface milling operations.  In accordance with the present invention, an aqueous solution containing orthophosphates is introduced into the formation to immobilize contaminants by forming a relatively stable precipitate.  For example, radionuclides such as uranium, thorium or radium form stable precipitates with orthophosphates.         When the formation fluids contain a high concentration of carbonates, the formation fluids are treated to reduce the carbonates concentration to levels which do not substantially interfere with the phosphate precipitation of contaminants.

Abstract: ABSTRACT A video amusement system in which a player must direct his craft along branching paths and the corresponding scenery ahead of the craft, as observed from the vantage of the craft's cockpit, is displayed on a scree.  To eliminate discontinuities in the display of the scenery, the successive frames of scenery sequences corresponding to parrallel branching paths are interleaved.  This allows the read head of the videodisc reader to read the frames of a praticular sequence without skipping more than a few tracks at a time, where on the skipped tracks are recorded the frames of the scenery sequences corresponding to parallel branching paths not selected by the player.  In the first preferred embodiment the fields of each frame are recorded on opposing 180° portions of adjacent track, not successively on a 360° portion of track.  The videodisc is read by skipping tracks during the blanking interval at the end of each field, in accordance with the fast forward mode.  In the second preferred embodiment, the field of each frame are recorded in succession on a 360° portion of the track. In this case, the video disc is read by skipping tracks during the blanking intervals at the end of each frame.

Abstract: USE OF WATER-ABSORBING, HIGHLY-FILLED POLYURETHANE(UREA) COMPOSITIONS FOR BIOLOGICAL     TREATMENT OF WASTE-CONTAINING LIQUIDS       ABSTRACT OF THE DISCLOSURE The present invention relates to the use of non-floating, non-abrasive, highly-filled polyurethane (urea) compositions of high water-absorbability, which during their production contain no cells capable of growth as carriers for biomasses in the biological treatment of waste-containing liquids.  These carriers have a filler content of greater than 15% by weight and less than 95% by weight (based on the moisture-free weight of the filler-containing polyurethanes).  The fillers are selected from the group consisting of natural materials containing finely-divided fossil lignocelluloses or the secondary products thereof (e.g., peat, lignite, mineral coal or coke), active carbon, finely-divided distillation residues, inorganic fillers, homogeneous or cellular plastics particles (and more particularly polyurethane foam (waste) particles) and mixtures thereof.  The polyurethane (urea) is a hydrophilic and/or hydrophobic polyurethane(urea), and preferably contains cationic groups.  These highly-filled, polyurethane(urea) carriers have a water-absorbability exceeding 33% by weight of water in the swollen carrier.         These carriers allow improved treatment of industrial and municipal liquid waste to be achieved in biologically-operating treatment plants.  Treated waste which has reduced toxicity, a diminished smell, improved clarity and a very small residual content of organic, decomposable material is obtained due to the increased decomposition effect thereof.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for the semicontinuous separation of plasma from blood collects blood from and returns blood to an individual in an intermittent manner.          Blood introduced from, say, a donor is fed into membrane-type blood plasma separating means by a circulating mean so that plasma may be separated from the blood.  Some of the concentrated blood that results is pooled in blood reservoir means, and the remaining concentrated blood is mixed with newly introduced blood and fed into the plasma separating means to repeat plasma separation and, hence, concentration.  When a predetermined amount of blood has been introduced from the donor, some of the blood remaining in the system is returned to the donor by a blood feed circuit, while the blood remaining in the system is subjected to plasma separation and concentration again.          Separation of plasma is thus performed during both the blood introduction and return cycles without pause.

Abstract: ABSTRACT OF THE DISCLOSURE         A fuel delivery system particularly useful for supplying petroleum distillate fuels to a fuel combustions device is described. When such device is operated in cold ambient conditions, fuel clogging car. occur in the fuel supply lines. In the past, attempts overcome such problems have been directed toward applying heat to the portions of the condiut subject to restrictions or by introducing solvents into the fuel.         These steps are, however, unsatisfactory. In accordance with this invention, the fuel  supply conduits are drained of fuel upon shut-down of the associated engine or other  fuel fired device.  Upon an engine start-up command, a small quantity of fuel is warmed, preferably using an electric immersion type heater.  Once a sufficient fuel temperature is reached, the fuel conduits are reprimed with fuel. Since  the fuel does not cold soak in these conduits, fuel clogging problem are eliminated. Various methods for venting the fuel supply conduit enabling such pirging and priming is described.
