  • Patent number: 12051578
    Abstract: Connection includes transistor, transistor exciter controlled by the frequency generator and/or programmable unit, the power source of voltage, the unit with capacitors. The voltage power source is connected to the transistor through the unit with capacitors. The stabilizing non-inductive resistor is connected to the power supply branch for the magnetron with transistor. The power stabilizing non-inductive resistor is a resistor with the wire wound by Ayrton-Perry-type winding and/or the resistor with low value of the parasitic inductance on the basis of thin layers. The electronic control circuits of the gate of the transistor include a frequency generator with the cut-off switch and with support elements and also include an exciter with support elements. The connection with the stabilizing non-inductive resistor is used in case of the bipolar and/or multi-circuit pulse plasma generator. The depolarization voltage is led from the outside source through the capacitor to the depolarization block.

  • Patent number: 4680989
    Abstract: A vehicle speed-dependent and engine load-dependent hydraulic control device for heavy vehicles shifting between two gear ratios is provided with a modulator valve modulating main input pressure by action of the engine load-dependent pressure, a shift valve shiftable by action of modulated pressure supplied to the shift valve from the modulator valve through a signal valve and a signal valve shifting down by the action of a spring and the engine load-dependent pressure and vice-versa by the action of vehicle speed-dependent pressure. The control device is further provided with a pilot shuttle valve controlling supply of the higher of two pressures, the load-dependent pressure and a limiting pressure to the signal valve to shift down according to the operator's command.
