摘要： A switch regulator includes a controllable SCR switch that is coupled in series with a filter inductor and a horizontal deflection generator, and the series combination is coupled across a source of unregulated direct voltage for providing a path for an increasing current flow in the inductor during a portion of a trace interval in which the switch is closed. Horizontal rate signals are coupled from the deflection generator to the switch via a first winding for controlling the opening of the switch. A catch diode is coupled to the filter inductor to form a path for a decreasing current flow in the first inductor during at least a portion of a retrace interval. The first winding is coupled in series with a second inductor to form an arrangement that is coupled between the unregulated voltage and the SCR switch. A current in the second inductor maintains the switch conductive during a portion of retrace that varies in accordance with a beam current for improving regulation of an ultor voltage.

摘要： A synthesis of gold (I) cyanide is described which exhibits high yields and does not yield toxic gases (e.g., HCN). Gold (I) cyanide is important as a source of gold for gold plating baths. A synthesis of AuCN that does not involve evolution of toxic gases (e.g., HCN) is highly advantageous because no disposal problem is involved and the procedure is simpler and more straightforward.

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 video display apparatus includes a regulated transformer power supply that provides power to an external load device, such as a computer, via one winding on the power supply transformer. Operation of the video display apparatus without the external circuit attached may cause degradation of the other transformer winding load circuits due to insufficient transformer power transfer as a result of decreased external power supply loading. A diode is connected from the external load supply to another load circuit to supply power to the other load circuit when the external device is not attached. When the external device is attached, the diode is reverse biased and does not conduct.

摘要： In a horizontal deflection circuit output stage, a retrace pulse voltage is developed in a primary winding of a flyback transformer and transformer-coupled to a secondary winding and rectified for developing a high voltage. A portion of the transformer-coupled rectified voltage is combined in a voltage divider with a second rectified voltage. The second rectified voltage is produced in a peak rectifier from the retrace pulse voltage in the primary winding in a manner that bypasses the secondary winding. A screen grid voltage is developed at a terminal of the voltage divider. A change in beam current loading produces variations in opposite sense in the combined rectified voltages in a manner to regulate the screen grid voltage.

摘要： A first resonant retrace circuit is operable for generating a first voltage signal and a second resonant retrace circuit coupled to the first resonant retrace circuit is operable for generating a second voltage signal summed with the first voltage signal. An auxiliary winding of a flyback transformer in the first resonant retrace circuit generates a first feedback pulse signal representative of the first voltage signal. A regulator senses the summed first and second voltage signals and generates a second feedback pulse signal representative of the summed first and second voltage signals. The second resonant retrace means is responsive to the regulator. A resistive summing junction combines the first and second feedback pulse signals to generate a composite feedback pulse signal. A voltage level is generated indicative of the energy in the composite feedback pulse signal. An overvoltage protection circuit is responsive to the voltage level for disabling operation of at least one of the first and second resonant retrace circuits.
