Title: Dynamic hue control networks
Inventor: LOVELY JOHN D
IPC: H04N9/77
Filed: 1975-04-04
Granted: 1978-10-10
Abstract: DYNAMIC HUE CONTROL NETWORKS Abstract of the Disclosure Poor transmission characteristics generally produce hue errors at low luminance levels.  This comes about because of differential gain and phase effects in the transmission path between the modulator of the transmitter and the de-modulator of the receiver.  The hue control may be set such that high luminance flesh colours will be acceptably correct, but the dark areas often are incorrect with objectionable green tinges being present, especially in close-ups of dark skin, hair and shadow areas.  This problem is overcome by automatically increasing the demodulation angle  at low luminance levels.  A signal that varies in accordance with the luminance level automatically adjusts a phase shift network to effect a phase shift of the chrominance signal relative to the reference signal or vice versa prior to these signals being applied to the chroma demodulators.         .

Abstract: ABSTRACT OF THE DISCLOSURE A system for producing stable direct current voltages from the horizontal output transformer of a television receiver is provided.  It includes an oscillator operating at the horizontal frequency to supply drive signals through a wave shaping circuit to a switching amplifier.          The duty cycle of the switching amplifier is controlled by the wave shaping circuit which in turn is controlled by the voltage from a half-wave rectifier coupled with the output of the switching amplifier.  The operation varies the duty cycle of the output signals from the switching amplifier in such a way as to stabilize the rectified direct current voltage.

Abstract: SECONDARY AIR SUPPLY FOR VEHICLE ACCESSSORIES            Abstract of the Disclosure A vehicle engine secondary air system with an engine driven pump supplying air to the engine exhaust system is modified to supply air at consistently adequate pressure to one or more engine or vehicle accessories.  The normal diverter valve unit has its diverter port replaced by a non-closable accessory air outlet, which opens through a check valve to an accumulator tank and an expansible chamber motor.  The expansible chamber motor has a movable diaphragm which controls a valve associated with the activation chamber of the diverter unit.          When accumulator tank pressure falls below a reference level, the diaphragm opens the valve to admit  air of at least atmo-spheric pressure to the normally less than atmospheric activa-tion chamber, whereby the diverter valve closes the exhaust outlet and pump outlet pressure rises to recharge the accumulator tank above the reference level.

Abstract: APPARATUS FOR SENSING NOTCHES           Abstract of the Invention A device for sensing notches in an  edge of a longitudinally transported film strip has a two-armed lever pivoted at a point to one side of the film path to deflect in the film plane. One arm carries at its end a spring biased roller which rotates freely against the moving unnotched film edge but which is biased into engagement with a notch to deflect the lever. The other lever arm is contacted by the actuating button of a microswitch the internal spring of which biases the lever to a quiescent position. A preselected deflection of the lever from this position actuates the microswitch to indicate the presence of a notch. Stops limit the deflection of the lever which is essentially normal to the direction of film movement, deflecting from a just obtuse to a just acute angle when entrained by a notch. The microswitch may be replaced by a photoelectric switching arrangement.

Abstract: SHOCK ABSORBER WITH CONICAL      CONTROL ELEMENTS                  ABSTRACT OF THE DISCLOSURE    An adjustable energy absorber including a housing having a ram slidably extending therefrom.  A first control sleeve divides the housing into a pair of fluid chambers, which sleeve has an axially extending row of openings to provide communi-cation between the two chambers.  A second control sleeve sur-rounds the first sleeve and is nonrotatably connected thereto.          The first and second sleeves have compatible outer and inner conical surfaces, respectively.  The first and second sleeves are axially adjustable with respect to one another to form a narrow flow passage between the opposed conical surfaces.  Imposition of a force on the ram causes fluid to be forced from one chamber through the openings into the flow passage, and then into the other chamber.  By varying the width of the flow passage, as by axially moving one control sleeve relative to the other, the amount of energy absorbed by the fluid during the movement of the ram can be selectably adjusted.

Abstract: PHONOGRAPH RECORD PLAYER                ABSTRACT OF THE DISCLOSURE           In a phonograph record player, an improved control mechanism is provided for effecting lead-in movement of a tone arm from an elevated rest position outside the perimeter of a turntable to a selected set-down position on a record supported by the turntable so as to commence a play operation, and for effecting a return movement of the tone arm to its rest position upon the termination of the play operation.  In such control mechanism, a main lever is angularly displaced by a cam follower engaging in a cam groove of a control gear to effect the lead-in movement during turning of the control gear from a stop position to a play position, and to effect the return movement during the further turning of the control gear from its play position back to its stop position.  In order to prevent inadvertent turning of the control gear from its stop or play position, the cam groove has depressions in its opposite site walls, respectively, disposed adjacent the cam follower in the stop and play positions, respectively, and an additional lever is biased by a spring to urge an edge thereof against a roller on the main lever which engages such edge at different locations, and thereby presses the main lever in opposed directions, when the control gear is in its stop and play positions, for holding the cam follower securely in the depression then adjacent thereto.  The additional spring biased lever is rocked upon angular displacement of the main lever to cause a brake to frictionally resist, and thereby stabilize the lead-in and return movements of the tone arm.
