Abstract: ABSTRACT OF THE DISCLOSURE         Timing errors in a color television signal equal to a fraction of the nominal period of one cycle of color burst are corrected by clocking an analog-to-digital converter during each horizontal line interval of the television signal with two clock signals having the same nominal frequency equal to a multiple of that of the color burst.  During the color burst interval of each horizontal line, the analog-to-digital converter is clocked by a stable time base reference clock signal and the obtained digitized color burst is stored in a recyclable digital memory.  Following the color burst interval, the stored digitized color burst is regenerated for the remainder of the horizontal line and a clock signal derived for use in clocking the analog-to-digital converter.  The digitized television signal provided by the analog-to-digital converter is written into a clock isolator at times determined by the clock signal derived from the digitized color burst and, thereafter, read from the clock isolator at times determined by the reference clock signal.  Timing errors exceeding the nominal period of one color burst cycle are corrected by writing the digitized television signal from the clock isolator into a following random access memory and incrementally adjusting the memory's read time in accordance with such errors measured in steps equal to the period of one color burst cycle.          The stable time base reference clock signal is coupled to control the signal processing following passage through the clock isolator.

Abstract: ABSTRACT OF THE DISCLOSURE       Shift mechanism for a transmission is provided for en-gaging and disengaging a gear therein.  The mechanism is particu-larly designed to disengage the gear when the transmission is un-der a heavy load.  The mechanism includes a clutch dog or collar on a shaft, with the collar having at least one lug od tooth which is engagable with and disengagable from a lug or tooth on a gear rotatably carried on the shaft.  The clutch collar has a peripheral flange with a cam configuration on the side toward the gear.  A shifter fork has a projection or cam follower with a cam surface facing the cam surface of the flange.  To disengage the collar from the gear, the cam follower of the shifter fork is en-gageed with the cam surface of the clutch collar and forces it away from the gear to a disengaged position, even when the transmission is under a heavy load.

Abstract: METHOD FOR ASSEMBLING AN ELECTROCHEMICAL CELL  ABSTRACT OF THE DISCLOSURE          A method for assembling a primary electrochem-ical cell.  The method in accordance with the invent tion includes the initial step of arranging a plurality of cell components, each having an opening extending therethrough, relative to an elongated, slotted, expandable metal tube so that the tube is loosely disposed within and along the openings in the cell components and the cell components loosely surround the tube in a stacked array.  The cell components employed in this step include a plurality of anode structures each having a plurality of resilient, deflective portions facing in the dir-ection of the terminal member and lying within a flat, common plane.  Each of the deflective portions further has a contact edge facing in the direction of the terminal member.  An expanding member in the form of a solid metal rod is inserted into and progressively advanced along the expandable tube. The expanding member causes the tube to progressively and permanently expand outwardly by an amount to make direct physical contact with the contact edges of the deflective portions of the multiple anode structures, in succession,deflect the deflective portions of each anode structure, and thereafter maintain direct physical contact with the contact edges of each anode structure.  By virtue of the above expansion operation, the anode structures are secured to the expanded metal tube.

Abstract: ABSTRACT OF THE DISCLOSURE     An analogue voltage-to-digital converter has a voltage divider with a plurality of steps for comparison with the unknown voltage and in addition provides interpolation between steps to improve the accuracy.          Interpolation is effected by adding a ramp voltage to the unknown ramping through a magnitude equivalent to at least one step.   With one tap on the voltage divider selected, comparison of the unknown plus ramp voltage is effected successively as the voltage ramps.          By noting when the combined voltage reaches the level of one of the reference voltages and by counting the number of comparisons made from the time when the ramp voltage is at a predetermined magnitude and comparing this with the time taken to ramp through one or a plurality of whole steps, determination can be made of the magnitude of the unknown voltage to a fraction of a step.

Abstract: COMPOSITION OF A NOVEL IMMUNOGEN FOR          PROTECTION AGAINST DIARRHEAL DISEASE       CAUSED BY ENTEROTOXIGENIC Escherlchia coli ABSTRACT OF THE DISCLOSURE There is disclosed a novel immunogen which can be used for immunological protection against acute diar-rheal disease caused by enterotoxigenic strains of Escherichia coli.  The novel immunogen is provided by cross-linking the E. coli heat-stable enterotoxin with the E. coli heat-labile enterotoxin (either the complete holotoxin or just the B subunit of this toxin) by a con-jugation process in the presence of a conjugating agent, typically the water soluble carbodiimide, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide.  This results in a unique new molecule in that the toxic properties of each individual toxin are greatly reduced, the heat-labile toxin (or its B subunit) retains its antigenicity, and the heat-stable toxin acquires immunogenicity as a func-tion of the reaction.  Immunization with the cross-linked immunogen provides immunological protection in mammals against water secretion induced by strains of E. coli which produce the heat-labile or heat-stable enterotoxins, either singly or together.

The apertures for any container are usually uniform in size and the range of aperture size is from about 250 to about 1000 microns.  The size and distribution of the apertures    prolongs bait life due to the controlled release of bait from the container and the added protection against unwanted predators such as arthopods.  Furthermore the bait container permits the use of emulsified or minced bait produced from previously undesirable material, such as discards and non-edible fish parts taken from the fish processing industry.

Abstract: "PRESSURE SWING ADSORPTION MALFUNCTION CONTROL"                ABSTRACT To prevent plant shut-down in pressure swing adsorption systems, malfunctioning absorbers are blocked off while the plant operates at reduced capacity.  For controlling the system, physical variables are selected for the adsorbers, the pipelines and/or the valves of the pressure swing adsorption installation and are continuously measured, and unacceptable deviations between actual and desired values of these variables are evaluated as an indication of a defect in the adsorption installation.  To prevent an adsorber from being prematurely blocked out of the system, at least two variables pertaining to a single adsorber must show unacceptable deviations, e.g., the pressure of the adsorber and the condition of the valve.
