Abstract: Abstract of the Disclosure A video amplifier circuit for combining chromi-nance and luminance signal components and for supplying. resultant color representative signals to an image repro-ducing cathode ray tube comprises first, second and third transistors direct current coupled in series relation with a load circuit across an operating voltage (B+) supply.   The first and second transistors are of one conductivity (NPN) while the third is of opposite conductivity (PNP).          Luminance signals, which are direct current coupled to the third transistor (a voltage follower), are converted by means of a drive control resistor to provide luminance current drive to the other series connected transistors.          Chrominance signals are direct current coupled to the control (base) electrode of the first transistor which operates in conjunction with the second transistor as a cascode voltage amplifier for chrominance signal components.          Color signals are direct current coupled from the output of the upper (common base) transistor of the cascode amplifier to the cathode ray tube.  The common base transistor is biased at a relatively low voltage to permit use of a relatively inexpensive wide bandwidth device for the lower transistor of the cascode arrangement.

Abstract: REGULATOR FOR A DAMPER ASSEMBLY                    ABSTRACT OF THE DISCLOSURE   Many multi-room structures, such as office buildings and schools, constructed during the past several years include air conditioning systems to deliver either relatively warm or cool conditioned air from a central source thereof to each of the enclosures or rooms in the building. Typically, one or more ducts are employed to deliver the air to each enclosure.  Very often a damper assembly or similar mechanism is installed in the duct to regulate the flow of air to one or more diffusers or discharge outlets located in the enclosure being conditioned by the discharge of air thereinto.  The movement of the damper assembly may be responsive to changes in the conditioned air supply pressure and/or changes in the temperature of the enclosure.  The controls regulating movement of the damper assembly typically include control point setting means establishing a maximum level of conditioned air flow irrespective of changes in the supply air pressure.

Abstract: ABSTRACT OF THE INVENTION    Coal liquid having a dissolved transition metal, catalyst as a carbonyl complex such as Co2(CO8) is hydrogenated with hydrogen gas or a hydrogen donor.  A dissociating solvent contacts the coal liquid during hydrogenation to form an immiscible liquid mixture at a high carbon monoxide pressure.  The dissociating solvent, e.g. ethylene glycol, is of moderate coordinating ability, while sufficiently polar to solvate the transition metal as a complex cation along with a transition metal, carbonyl anion in solution at a decreased carbon monoxide pressure.  The carbon monoxide pressure is reduced and the liquids are separated to recover the hydrogenated coal liquid as product.  The dissociating solvent with the catalyst in ionized form is recycled to the hydrogenation step at the elevated carbon monoxide pressure for reforming the catalyst complex within fresh coal liquid.
