Abstract: HYDRAULIC SYSTEM PRESSURE CONTROL     FOR A POWER TRANSMISSION          Abstract of the Disclosure:         A hydraulic control for a power transmission has a regulator valve for controlling the hydraulic system pressure and a plurality of shift valves for controlling the automatic ratio change in the mission.  The shift valves are urged toward the higher ratio position by a governor pressure.  The shift valves, except the 1-2 valve, Are selectively sub-jected to separate modulated throttle valve pressures acting in opposition to the governor pressure and depending upon whether the respective shift valve is in the lower or higher ratio position  The modulated pressures are maintained at substantially zero for a portion of the throttle valve pressure range so that upshifting and downshifting will be sensitive to governor pressure and therefore vehicle speed only.         The regulator valve is subject to a variable bias pressure which is proportional to throttle valve pressure.  The bias pressure is controlled by a valve to be equal to the throttle pressure during the lower pressure portion of the throttle pressure range and to increase at a rate less than the throttle valve pressure during the remainder of the pressure range.

Abstract: ABSTRACT           An automatic temperature control system for regulating the temperature of a vehicle passenger compartment at an operated selected temperature.  The system employs an in-car transducer which senses compartment air temperature and emits a vacuum control signal to a vacuum operated servoactuator.  When ambient temperatures require heating, the servoactuator is operative to shut off the cooling refrigerant compressor and modulate the opening of the heater core water valve for controlling the temperature of forced air discharge from the heater core.  When ambient temperatures require cooling, the servoactuator closes the heater core water valve and intermittently opens and closes a switch for cycling the refrigerant compressor to modulate the temperature of forced air discharge over the refrigerant heat exchanger.  The transducer receives blower discharge air for aspirating in-car air for temperature sensing.  A minor portion of the blower discharge is diverted to impinge on the temperature sensor for sensing condensate freezing on the refrigerant heat exchanger.

Abstract: HOT SPRUE ASSEMBLY FOR AN INJECTION MOLDING MACHINE        ABSTRACT OF THE DISCLOSURE     A hot sprue assembly is provided for control-ling flow of molten material into the mold cavity of an injection molding machine.   The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs.  The hot sprue assembly includes a hot sprue bushing cooperating with a general-ly conically shaped dispersion head to define an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc.  Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during solidification of the material within the mold cavity, permits the mater-ial within the mold cavity to solidify up to the gate without substantial solidification of material within the sprue assembly.  The gate is disposed at a plane recessed slightly from the general plane of the solidified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.

Abstract: MAGNETICALLY TORQUED NUTATION DAMPING                Abstract A system for actively damping nutation of an earth orbiting spacecraft and/or aligning the pitch axis of a momentum bias spacecraft with some external reference includes a magnetic torquing means, which is energized with currents of appropriate polarity and magnitude to effect the necessary torque to reduce nutation by producing in the roll/yaw axis of the spacecraft a magnetic dipole for reaction with the earth's magnetic field.  A roll sensor produces signals proportional to and representing the direction of the attitude error of the satellite with respect to a desired attitude.  A control signal is generated a predetermined time period after the roll error exceeds a predetermined threshold.  The predetermined time period is a fraction x of the nutation period tn of the satellite or x + n(tn) where n is an integer.
