Abstract: CONTINUOUS CASTING MOLD SIDE WALL ADJUSTMENT SYSTEM            ABSTRACT OF THE DISCLOSURE     An apparatus and method for accurately and quickly adjusting the distance and tilt angle or taper between movable side wall mold plates in adjustable width continuous casting mold sections. A pair of spaced primary mold members with movable side wall mold plates therebetween, form an open ended mold cavity. Each side wall mold plate is connected to upper and lower fixed mold supports by separate upper and lower adjustable length connectors which have their inner ends hinged to the side wall mold plates. Each connector has an axial bore receiving a transducer core for reciprocating movement along a linear path. A cylindrical transducer coil housing in the bore, fixed relative to the mold cavity center, surrounds the movable core. The transducer core has one end anchored to a side wall mold plate. Adjustment of the side wall mold plate causes corresponding axial movement of the core relative to the coil enabling calibration of an electrical signal for computing the distance of the side wall mold plate from the mold cavity center. By using a separate linear transducer on each of the upper and lower connectors, any tilt or taper of the side wall may also be determined. Alternatively, one linear transducer may be replaced by an angular transducer, e.g., an inclinometer, to measure the effective tilt or taper of the side wall mold plates.

Abstract: Abstract of the Invention A process and material is disclosed for disposing of SOx laden regeneration flue gas by contacting the flue gas under selected reaction conversion conditions in a reaction zone with a high metal containing particulate material to remove sulfur oxides.  Reaction conditions are such that the sulfur oxides are removed by selective adsorption or reaction with the metals to yield metal sulfites - sulfates.  The metal sulfite -sulfate containing material is regenerated-rejuvenated in a reductive atmosphere or oxidative-steam atmosphere and the regenerated solid particulate material is recycled back to the SOx removal zone.  The SOx in a reductive atmosphere is recovered as hydrogen sulfide and in the oxidative-steam atmos-phere as sulfur oxides.  The particulate material of the inven-tion can be active or deactivated catalyst from FCC and/or RCC operations containing sufficient metals, such as Ni-V-Fe, to react with the sulfur oxides or a low activity high metals con-taining sorbent material such as obtained from a metal recovery system in front of a reduced crude conversion unit.

Abstract: A B S T R A C T A multiple phase modulator which employs no transformers and which is formed as a single circuit array is described.  Conventional modulators used transformers which could not be fabricated as integrated circuitry and involved the use of two circuit arrays which caused phase errors.  In the simplest form of the invention, i.e. a 4-phase phase modulator circuit, there is a first exclusive OR circuit having a first input to which the carrier wave is fed and a second input to which one of the two base band digital signals is fed.  The resultant 2-phase phase modulated signal is halved in frequency by a frequency divider and this signal is then fed to a first input of a second exclusive OR circuit.  The second base band digital signal is fed to a second input of the second exclusive OR circuit which also carries out 2-phase phase modulation to provide  the desired 4-phase phase modulated signal.

Abstract of the Disclosure A process for the total or partial elimination of aspartic acid and glutamic acid from a protein hydrolyzate or a mixture of aminoacids is described, which consists of passing the hydrolyzate or mixture of aminoacids in solution on an anion exchange resin and then washing with water or eluting the aminoacids from the resin.  Aspartic acid and glutamic acid are at least partially separated from the other aminoacids because of their affinity for the resin which is greater than the affinity of the other aminoacids. The resulting mixtures of aminoacids may be used as such or may be further adjusted by addition of valine, leucine, iso-leucine, and arginine to give products valuable in clinical nutrition.

Abstract: Abstract The pump or pumps for supplying fluid to the two ends of a double-acting cylinder include a direction control, such as a direction control valve, shiftable between extend and retract conditions.  A drive mechanism for the direction control includes a rotary hydraulic motor and a driven rotary drive mechanism for shifting the direction control.  Hydraulic fluid is supplied to the drive motor through parallel connec-ted start and stop valves.  The start valve is opened in response to the movements of the hydraulic cylinder toward a stroke limit.  The stop valve is operated in response to the shifting of the direction control, so that the motor is operated inter-mittently to reverse the direction control when the cylinder reaches the limit of an extend or retract stroke.  The stop valve is controlled by the drive mechanism in timed relation with the shifting of the direction control.  The start valve may be closed by that drive mechanism in timed relation with the opening of the stop valve.
