摘要： A display system controls vertical zoom and panning. A video display has a first format display ratio. A circuit, for example one generating a raster, maps on the video display an adjustable picture display area represented in a video signal having a vertical synchronizing component. The picture represented in the video signal has a second format display ratio. A vertical height control circuit, for example one controlling the vertical height of the raster by controlling the vertical deflection current, selectively enlarges the picture display area relative to the video display. A panning control circuit adjusts in phase a vertical blanking interval relative to the vertical synchronizing component to control which portion of the enlarged picture area is displayed and which portion is not displayed. The format display ratios can be the same or different, for example 16.times.9 for the video display and 4.times.3 for the picture, in the latter case.

摘要： A first voltage-to-current converter responsive to a picture height adjustment control signal generates a first current in a capacitor for producing a trace portion of a sawtooth signal in the capacitor having a rate of change that is adjustable in accordance with an adjustment of the control signal. A second voltage-to-current converter responsive to the control signal generates a second current in a resistor for producing a third signal that is adjustable in accordance with the control signal. The sawtooth and third signals are coupled via a differential amplifier to a vertical deflection winding to produce a vertical deflection current in accordance with a difference between the sawtooth and third signals such that picture height adjustment does not affect vertical centering.

摘要： In a vertical sawtooth generator of a D.C. coupled vertical deflection circuit, a vertical deflection amplifier generates a sawtooth signal. Magnitudes of the sawtooth signal in first and second instants of its trace period are determined in accordance with first and second D.C. signals, respectively. The first and second D.C. signals are adjusted during service to control the raster height and the raster centering such that while the raster height is adjusted, raster centering is not significantly affected, and vice versa.

摘要： An apparatus adapted for recovering compressible refrigeration fluid from a refrigerator means and delivering the recovered fluid under high-pressure conditions along a line to a receptacle, in fluid communication and in sequence along the line. An accumulator means to which refrigeration fluid from the refrigerator means in gaseous form is drawn, a compressor to compress the refrigeration fluid from the accumulator and create a vacuum condition for drawing refrigeration fluid from the refrigerator means, and a condenser to liquify the refrigeration fluid for delivery to the receptacle, the improvement characterized by a secondary receptacle being provided, communicating with the line between the condenser and receptacle and with the line upstream of the accumulator, and a valve means in the line between the secondary receptacle and the compressor arranged, when the pressure in the secondary receptacle exceeds a predetermined value, so that the valve will open to allow some of the refrigeration fluid to flow back to the compressor for recondensation, to thereby lower the pressure in the receptacle.

摘要： Retrace pulses are integrated by an R-C network to produce a ramp signal. The resistive member of the R-C network is bypassed by a diode to provide rapid retrace at the conclusion of the ramp portion of the integrated signal. A voltage divider at the output of the integrator adjusts the DC level of the ramp signal without affecting the constant of integration of the R-C network.

摘要： A phase adjustment circuit for display apparatuses operates to vary the phase of an input sync signal to produce a pseudo sync signal for use in positioning an image at the center of a display screen. The circuit comprises a voltage comparator (50) having two input terminals thereto maintained at the same d.c. voltage, and one input terminal thereto is supplied through a d.c. blocking capacitor (C.sub.2) with a saw-tooth wave signal (P.sub.1) obtained by integrating the input sync signal, whereby a pulse having an edge of its pulse waveform situated always at the midpoint position between the two input sync signals. Pseudo sync signal generation means (101, 102) are triggered by the edge of the pulse waveform so that the pseudo sync signal of a phase different from that of the input sync signal is formed.

摘要： A variety of circuits for centering pictures on the screens of television tubes are characterized by the use of a picture centering variable resistor arranged in a loop including the horizontal and/or vertical deflection coils on said tubes. The variable resistor is connected by a brush or slidable contact with a source of direct current the magnitude and direction of which through the deflection coils controls the positioning of the associated picture. In connection with certain of the aforegoing circuits, provision is also made for high voltage stabilization.

摘要： A display centering system comprises a cathode ray tube having a metalized screen which is etched to provide at least a pair of electrically discrete sectors. The split screen acts as a target anode; and is operated at a potential to collect all primary and secondary electrons. The beam current is momentarily increased at predetermined points of the raster independently of the normal video signals; and the differential anode currents between the two halves of the split screen are measured at such points of the raster to determine positioning errors. In order to avoid excitation of the phosphors to a visible level, the points in the raster at which the beam current is momentarily increased is successively varied from field to field and from frame to frame. The metalized layer of the screen is preferably split along a line passing through the center of the display so that the display may be centered with the highest accuracy. Information can be readily displayed at the center of the screen, since at any given point the video signal will only occasionally be affected by the pulse of increased beam current which is used to establish the center of the display.
