Abstract: ABSTRACT OF THE DISCLOSURE         An improved color corrector is disclosed which is of the type that separates the color burst component from a color video signal and uses the color burst in a phase locked loop to generate a continuous color subcarrier signal that is used to provide frequency and phase error correction of the chroma component of the color video signal.  The corrector uses a wide bandwidth phase locked loop and has means for adding a color corrected chroma component from a present horizontal line of the video signal to a color corrected chroma component delayed by one horizontal line to cancel other circuit induced phase errors that are present due to the use of the wide bandwidth phase locked loop and the gating of the color burst thereto using a horizontal sync related burst gate signal.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is apparatus and method for continuously com-pensating for electrode drift during the measurement of the par-tial pressure of oxygen by the net charge transport technique.          The apparatus derives a correction factor from variations in wave-forms representing charge returned from an electrochemical cell after successive interrogating voltage pulses.  These waveforms are independent of oxygen partial pressure hut dependent on elec-trode parameters thereby permitting drift to be monitored and oxygen partial pressure measurements  to be corrected.

VOLGYESI     ABSTRACT OF THE DISCLOSURE     The disclosure relates to a respiration monitor primarily intended to be used in hospitals to provide an alarm signal in the event of cessation of breathing by a patient.  The monitor includes a sensor having a housing which defines an air passageway and which is adapted to be placed in communication with the airway of a patient so that air inhaled and exhaled by the patient will flow through said passageway.  A pair of electrical conductors are located in the passageway in the path of air flowing therethrough in use.  The conductors are spaced from one another and form a capacitor having a dielectric formed by the air between said conductors, so that changes in the humidity of the air in said passageway during inhalation and exhalation by the patient in use will cause corres-ponding cyclic variations in the capacitance of said capacitor.  The monitor also includes electrical circuit means coupled to the conductors and adapted to provide an alarm signal in the event of cessation of said cyclic variations in capacitance.

Abstract: ABSTRACT    A degasser system having a central container and degasser tubes extending to the central container.  A vacuum is maintained within the tubes and the container by means of a vacuum pump while liquid is extracted from the central container by a pump.  A gas cut liquid is drawn into the tubes by vacuum and conditioned to assume a helical path through the tubes.  The liquid is then dispersed into the tank where it is allowed to collect.       The degasser intake is throttled as a function of the level of liquid within tube container.  The accumulated gas within the degasser is extracted from a central location in one of the tubes.  The pump includes a housing for total emersion of the pump body, dual inlets, straight, radial impeller vanes, multiple volutes and an extended drive shaft to accommodate gas cut mud.

Abstract: REFRIGERATOR DEFROST CONTROL WITH CONTROL OF TIME INTERVAL BETWEEN DEFROST CYCLES                 ABSTRACT OF THE DISCLOSURE        Door open time in an automatic defrost refrigerator is accumulated in the memory of a microcomputer.  Normal cycling of defrost is delayed by inactivating the defrost timer during periods of light usage of the refrigerator until a minimum predetermined accumulated door open time is reached.  Provision is made for sensing interior refrigerator temperature to override the delaying effect of the door open measurement when a sensed over-temperature condition indicates an abnormal build-up of frost on the evaporator coils even though the refrigerator is experiencing relatively light usage.  A maximum compressor run time interval between defrost cycles is provided for when no door opening occur, as during vacation periods.

Abstract: Abstract of Technical Disclosure A heel binding for a cross-country ski has opposing latches movable toward each other under engagement by spaced apart flexible beams that force the latches together to capture a projection from the heel of a skier's shoe to hold the heel to the ski.  The inside surfaces of the latches are cam-shaped to allow releasing force on the pin to urge the latches outward against the flexible beams, and to release the pin when the force is substantial enough, as in a fall.

Abstract: HIGH SPEED PAPER DRYING ABSTRACT OF THE DISCLOSURE An improved paper drying process and machine are described in which the paper web is supported independently of velocity-induced stresses thus permitting operation at speeds significantly in excess of the prior art for each paper grade. The process requires: (1) transporting the web on a supporting fabric that travels from the last press nip through at least the initial portion of a drying section; and (2) holding the web onto its supporting fabric by employing forces normal to the major web surfaces sufficient to overcome those forces which tend to lift the web from its supporting fabric. The web on its supporting fabric travels a serpentine path through the drying section about drying cylinders with the web alternating between direct contact with a drying cylinder followed by indirect contact with the subsequent cylinder. The principal holding forces are preferably pressure differentials created by vacuum boxes arranged to effectively hold the web to its supporting fabric on all portions of the web-fabric combination where the web is not in direct wrapping contact with the drying cylinders. The fabric supports the web at least until the web has attained sufficient strength through increased dryness to resist breaking stresses at the selected machine speed. The products made by the process of this invention possess a unique toughness or stretchability not found in conventionally prepared papers that have been strained or stretched during manufacture. Processes and machine arrangements designed to balance stretchability with certain desirable stiffness properties are disclosed. Pulp furnishes may now be selected for their contribution to product qualities, such as higher finished product tensile strength, rather than principally for wet strength. For example, chemical pulps may be significantly reduced or eliminated from newsprint furnishes where their purpose has been principally to permit economic paper machine speeds. The invention makes attainable speeds approaching twice current operating levels for each paper grade.
