Abstract: COLOR TELEVISION RECEIVING SYSTEM UTILIZING MULTIMODE INFERRED HIGHS s2435                 CORRECTION TO REDUCE COLOR  INFIDELITIES                 ABSTRACT OR THE DISCLOSURE         A color television receiving system for NTSC-type signals is provided with signal processing circuitry and methods for reducing the visibility of color and luminance infidelities, such as incorrect or inverted highs, over-modulation and rectification which are visible in regions of sharp transitions from one color to another or in regions of concurrent high color saturation and significant high frequency detail.  Such infidelities are sub-stantially reduced by effectively supplementing either the chrom-inance or the primary color signals with inferred high-frequency chrominance components derived from signal information discovered to be inherently available in NTSC-type signals and their implicit constraints.  Specifically, in one form of the invention it has been found that in regions of sharp color transitions and in regions of high color saturation, relevant high frequency chrom-inance components can be scaled from the high frequency portion of the received monochrome signals in accordance with different respective scaling algorithms.  A receiving system is provided with multimode inferred highs correction circuitry responsive to a received NTSC-type signal for automatically deciding which, if any, correction modes are appropriate for a given time and fre-quency region of the received signal and for automatically enabling correction circuitry for providing the appropriate inferred high frequency correction signals.

Abstract: MOTOR CONTROL SYSTEM                     ABSTRACT OF THE DISCLOSURE           A motor control system for controlling the speed and direction at which a motor operates.  A drive circuit is provided for supplying a drive current to the motor, the magnitude of the drive current being determinative of the speed at which the motor operates.  A direction-determining circuit determines the direction at which the motor operates and, for example, may comprise a steer-ing circuit for steering the drive current to the motor in first and second current paths.  A potentiometer having a resistance connected between first and second terminals and an adjustable wiper which is settable along the resistance is used to determine the desired speed and direction of operation of the motor.  The setting of the wiper includes a predetermined zero speed setting which, preferably, is at some intermediate point along the resistance.          A power supply having a power terminal and a reference terminal pro-duces an operating potential across these terminals.  The power terminal is coupled to the potentiometer wiper and the reference terminal is coupled to one of the potentiometer terminals.  A resistor couples the other potentiometer terminal  to the power supply reference terminal.  The potentiometer wiper is coupled to the drive circuit and the potentiometer terminal which is coupled to the resistor also is coupled to the direction-determining circuit.          The setting of the wiper determines the magnitude of the voltage supplied to the drive circuit so as to determine the motor speed, and the setting of the wiper also determines the magnitude of the voltage supplied to the direction-determining circuit by the poten-tiometer terminal so as to determine the direction at which the motor operates.  Advantageously, only a single source of operating -i-potential need be used with the potentiometer to determine motor direction.     -ii-

Abstract: A RECEIVER FOR COMPATIBLE AM STEREO SIGNALS                           ABSTRACT       An improved AM stereo receiver for receiving broadcast signals having the form (1 + L + R)cos(.omega.ct + 0)where 0 is arc tan(L - R),/(1 + L + R).  The sum signal (L + R) is demodulated in an envelope detector and coupled to a matrix. The uncorrected difference signal is demodulated in a synchronous detector, a corrector circuit derives the cor-rection factor, and a divider circuit provides the corrected difference signal.  During tuning, and until a PLL is locked on the carrier frequency, the receiver is locked into the monophonic mode and tuned on the monophonic signal.  When the PLL locks, the difference signal is coupled through to the matrix for stereophonic mode operation.

Abstract: FUEL INJECTION SYSTEM AND METHOD  FOR INTERNAL COMBUSTION ENGINE                 ABSTRACT OF THE DISCLOSURE      An air and fuel mixing device incorporates a Venturi throat or other mixing means for feeding a highly combustible mixture of fuel and pressurized air to an electrical fuel injector valve or directly to the intake manifold in a system for starting an internal combustion engine.  The system replaces the choke in a conventional electrical ignition type internal combustion engine.  The fuel injector valve is controlled to inject a limited quantity of a highly combustible atomized air-fuel mixture into the engine intake manifold during engine startup.  Startup is achieved with minimum fuel waste and pro-duces a minimum of exhaust pollutants.  A modified form of the invention is shown as employed in a fuel injection type inter-nal combustion engine system wherein high pressure air-fuel mix-ture is fed to the fuel injectors solely through use of a conven-tional low pressure fuel pump and air supply. The injectors operate to discharge a highly volatile, combustible, air-fuel mixture under pressure, instead of raw fuel thus significantly increasing combustion efficiency during engine startup to mini-mize fuel waste and reduce deleterious exhaust emissions. An-other modified form of the invention is shown wherein the system is employed to feed a mixture of fuel and pressurized air to the engine intake manifold in response to an acceleration command from the engine throttle control during normal engine operation.          This eliminates the need for the notoriously troublesome carbur-etor accelerator pump now in conventional use.
