Abstract: PROCESS FOR THE RECOVERY OF PROTEIN  HAVING IMPROVED SOLUTION CLARITY     Abstract of the Disclosure A process for recovering protein having improved solution clarity at acid pH from proteinaceous aqueous solutions comprising admixing with a proteinaceous aqueous solution a phosphate to form a phosphate complexed solution, adjusting the pH of the phosphate complexed solution to a neutral range of from about 6.0 to about 8.0 by the addition of base to form a precipitate and a pretreated proteinaceous aqueous solution, separating the precipitate from the pretreated proteinaceous aqueous solution to provide a separated precipitate and a separated pretreated proteinaceous aqueous solution, admixing with the separated pretreated proteinaceous aqueous solution a medium chain length polyphosphate to form a protein-phosphate complexed solution, adjusting the pH of the protein-phosphate complexed solution to an acid range of from about 4.5 to about 2.0 by the addition of acid to form a protein-phosphate pre-cipitate and a supernatant solution, separating the protein-phosphate precipitate from the supernatant solution, dispersing the separated protein-phosphate precipitate in water having a final pH from about 5.0 to about 10.0 to form a protein-phosphate dispersion, contacting the protein-phosphate dispersion with an anionic ion exchange resin, and recovering the effluent containing protein.  The effluent containing protein is useful for prepar-ing fortified acidic beverages, which require protein solubility and maintenance of clear solutions at acid pH.

Abstract: ABSTRACT          In a servomotor having a first diameter piston concentric to a second diameter piston for supplying a braking system with a first pressurizing force and a second pressurizing force in response to an operator input.  A transfer valve has a first face and a second face which are located on opposite sides of a radial bore in the second pis-ton to receive a first pressurizing force.  The transfer valve has an axial passageway therethrough which communicates relief or reservoir pressure to the first and second faces of the transfer valve to pro-vide a balance pressure force on the same.  A spring holds the second face of the transfer valve against a seat to prevent communication of the first pressurizing force into the relief chamber.  When a pre-determined first pressurizing force is obtained, the actuator in res-ponse to an operator will overcome the spring and move the second face away from the seat to allow the first pressurizing force associated with the first piston to be proportionally communicated into the relief chamber.  As the first pressurizing force is communicated into the relief chamber, the output from the servomotor is transferred to the second piston to provide an additional operational or second pressuriz-ing force to activate the wheel brakes of the vehicle.
