Abstract: OIL RECOVERY METHOD UTILIZING A SURFACTANT SLUG     DRIVEN BY WATER OF A CONTROLLED SALINITY               (D#74,785-F) ABSTRACT OF THE DISCLOSURE           The efficiency of a low tension surfactant flooding program is improved by first determining the upper and lower boundaries for the range of injected water salinities, that, when intermingled with the injected aqueous surfactant slug will enable the surfactant to resist partitioning into an oil and/or emulsion phase and thereby continue to operate with maximum effectiveness. The water in the driving slug is formulated to fall within the specified salinity boundaries and is then injected at the appropriate time in the sequence of steps in the oil recovery operation.                             -I-

Abstract: ABSTRACT         The invention relates to a method for the interference-resistant transmission by radio of speech signals processed by means of a vocoder using spread frequency bands (SSMA) or a rapid radio frequency change.  To avoid the danger of self-interference caused if a great many stations simultaneously use the same frequency band or the same radio frequency-channel collective, it is proposed that the transmitter and the receiver be activated in the rhythm of the intrasystem frame timing during a frame period only if useful information is also present.  In this way on average approximately 40% of the transmission time for two-way connections and more than 60% of the transmission time for duplex circuits may be saved and thus the self interference of the system may be reduced accordingly.

Abstract: Switch Actuator Apparatus Abstract This invention relates to an apparatus for actuating an electrical switch which eliminates the problems of over stressing and inadvertent cyclical actuation of the switch and flexing of electrical connecting wires.  The apparatus has an actuator spring movable in response to a load applied to a seat assembly for applying an actuating force to the switch of a magnitude less than the load applied to the seat assembly and a bracket for limiting the magnitude of force applied to the switch to a preselected maximum value.  The apparatus eliminates premature switch failure, inadvertent cyclical switch actuation and electrical wire breakage.  The actuating apparatus is particularly useful on a vehicle such as a lift truck.

Abstract: ABSTRACT         A spacer for loading pallets comprises a tubular member having a number of pointed securing tabs (3a) adapted to penetrate into and connect the tubular member to a deck-forming member of the loading pallet, and a number of support members (3) extending at a right angle to the securing tabs and being formed, like the securing tabs, in one piece with the tubular member.  The spacer is prepared from a thin-walled sheet metal portion, which has been given a polygonal tubular shape in cross section by axially extending bending zones (7) located in border areas between securing tabs (3a) and support members (3).          Each tube wall portion (12) defined by two adjacent bending zones (7) and associated to a supporting member (3) extends at an angle to two other adjacent tube wall portions (12) located on opposite sides thereof.

Abstract: CRANIAL DRILL                          ABSTRACT            A completely disposable, permanently assembled drill for perforating bone structures, which includes a generally annular drill body.  A primary drill member is slidably and rotatably received in the distal end of the drill body.  A driver is slidably and rotatably received in the proximal end of said drill body.  A pin and slot-type spring biased clutch is disposed on the confronting surfaces of the drill member and driver.  The pin of the clutch projects through the triangular openings and the sidewall of the drill body so as to limit the throw of the clutch and to link the drill body and drill member together.  The interaction of the pin against the triangular side of the slot in the drill body produces a component of force which tends to urge the clutch apart. When the drill is placed against the bone structure with a force sufficient to overcome the spring bias, the clutch will engage and the driver and drill member and the drill body will rotate together.  The counterbore on the drill body provides a support for the drill mechanism so that the drill member may release when it penetrates the bone structure without having the remainder of the drill move in the direction toward the cranial cavity. The sleeve holds the drill body and driver together and is made of a material that degrades when subjected to sterilization.

Abstract: ABSTRACT     A composition for treatment of siliceous formations, comprising an aqueous solution having a phosphoric acid concentration in the range of from about 10 to about 30% by weight, to which is added at least one flourine donor compound in an amount to provide a generated hydrofluoric acid concentration in the range of from about 1 to about 7% by weight.  The composition is quite reactive towards clay and silica but, unlike conventional mud acid, displays significantly retarded reactivity towards calcium carbonate.  The preferred fluorine donor is ammonium bifluoride, and an especially effective phosphoric acid solution is a Turflo? solution, components of which serve to further potentiate calcium carbonate reactivity retardation.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a tool for compressing a helical spring of the type typically used in a MacPherson strut suspension system.  The tool comprises a pair of spaced apart shoes each having a helical groove formed therein for engaging a portion of the coil of the spring.  Each shoe also includes a latchable locking device extendable over the respective helical groove for maintaining the coil of the spring within the groove during the compression operation.  The two shoes are maintained in a spaced apart relationship with the associated grooves in facing relation to one another by means of a threaded shank member.  The threaded shank member is employed to effect movement of the spaced apart shoes toward and away from one another during the operation of the tool.

Abstract: ABSTRACT         A latch mechanism is presented which is useful with a machine which gathers crop material from a windrow and forms it into large round bales.  The latching mechanism senses bale density while holding the opposing faces of the tailgate closed during the bale forming operation.  Density is sensed by spring mounting the latch slides so that the tailgate comes slightly ajar when pressure in the baling chamber builds up. The amount of separation of the opposing faces of the tailgate is sensed and when it exceeds a specified amount, initiates a bale discharge sequence.  The tailgate lifting mechanism is inter-locked with the latch release to assure safe operation of the system.

Abstract: ABSTRACT        An improved method which differentiates or separates heterogeneous populations of fast and slow acid producing strains of bacteria by growth of the strains under closely controlled unique conditions so as to allow the selection of a colony of one or the other strains is described   Preferably a gelled, solid growth medium containing in admixture:   (1) milk protein, a milk protein derivative  or a milk protein substitute; (2) an acid pH sensitive color change indicator; and (3) a buffering agent is used.  The colonies have a contrasting color within and around them because of the effect of the acid produced by the bacteria on the indicator.  The growth of the bacteria is under anaerobic or near anaerobic conditions in order to achieve certainty in the colony selection for fast or slow acid production.  The bacteria can also be mixed with phage which inhibit or kill the members of a heterogeneous or homogeneous population of bacteria on the medium and grown to produce phage resistant colonies.  The relatively large colonies which exhibit enhanced acid production and proteolysis of the milk protein on the plating container are selected for commercial use in preparing fermented products, particularly fermented foods.
