Abstract: ABSTRACT OF THE DISCLOSURE           In the displacement of crude oil through a sub-terranean reservoir with an aqueous displacement fluid, improved oil recovery is obtained by providing a salinity contrast between the displacement fluid and aqueous forma-tion fluid.  The salinity of the displacement fluid is selected such that at least one mixture of the aqueous displacement and the aqueous formation fluid will have the minimum interfacial tension between the displaced crude oil and mixtures of these fluids.  The minimum interfacial tension between crude oil and mixtures of aqueous dis-placement and formation fluids can be determined by mixing these fluids such that some mixtures contain from essen-tially none to essentially all displacement fluid and det-ermining the interfacial tension between the mixtures and the crude oil.  The displacement fluid is a micellar fluid followed by a polymer-containing aqueous fluid.  Further improvements in oil recovery are obtained when this salinity contrast is provided and the salinity of the polymer-containing fluid is less than the salinity of the mixture which provides the minimum interfacial tension with the crude oil.

Abstract: Abstract of the Disclosure A fluid mixing system and method is disclosed for automatically mixing precise concentrations of photographic processing chemistry to be used in an X-ray film processor. The system produces a fresh batch of mixed solution whenever a previous batch has been reduced to a predetermined minimum volume.  A pair of substantially identically constructed mix-ing units are provided to produce both developer and fixer solutions for film processing.  Each unit has:  a chemical supply structure for supplying chemicals from contaninerized supplied;  a storage and mixing tank structure which underlies the chemical supply structure and defines a reservoir for mixing the chemistry with water; a water input valve for selec-tively introducing water under pressure into the tank structure; control apparatus for conditionally controlling operation of the water valve; and a chemical release assembly  which is coupled to and actuated by the water valve.  The chemical release assembly is operated by the pressure of the water as the water is admitted through the water valve.  Operation of the release assembly causes piercing of the containers, allowing the chemistry to drain into the reservoir.  The pres-surized water creates a swirl for agitating and thoroughly mixing the chemistry and the water.

Abstract: BAG FORMING, FILLING AND CLOSING MACHINE                            ABSTRACT         This relates to a bag forming machine wherein a continuous tube is formed from a continuous web, the tube having a side seam and being cut off at predeter-mined intervals to form short tubes with closed bottoms.          The tubes are placed on mandrel assemblies of a turret and the mandrel assemblies, as the turret is indexed, are actuated so as to axially elongate the closed tubes while holding the open end of each tube against move-ment, thereby generally forming a flat bottom on the tube and triangular bottom portions.  The turret is next indexed so as to plow down the triangular bottom portions flat against the flat bottom portion followed by further indexing of the turret to heat seal the triangular portions to the flat bottom portion and then cool the heat seals.  Finally, each closed bottom bag is gripped by a combined rotator and orientation device wherein the side seam of the bag is rotated to a selected orienta-tion.  The flat bottom bag is then transferred from the turret into a pocket of a conveyor which directs the bag to a filler and then a heat sealer for closing the closed bag.  In order to effect the transfer of the bag from the turret, it is necessary that an outer mandrel of each mandrel assembly be projected radially from the turret a considerable distance.  This is effected by way of a plunger carrying the mandrel and an associated cam. The cam has a sector thereof which is radially movable relative to the remainder of the cam by a rocker arm which is actuated in timed relation to the indexing of the turret so as to provide for the necessary outer mandrel travel.
