Abstract: 723,720. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 17, 1952 [Nov. 20, 1951], No. 28961/52. Class 38 (4). [Also in Group XL (c)] In an arrangement for deriving a stabilized high-voltage direct current from the rectified output of a thermionic valve oscillator, the oscillator is controlled in accordance with both the output voltage and the load current to obtain level compounding. The output of the oscillator circuit 1, 2, 4 is stepped up by transformer 3 and rectified by rectifier 10, the load current being passed through a resistor 11 to control a valve 14 so that a voltage proportional to current appears across condenser 20. A control voltage proportional to the output voltage is obtained across a resistor 19 by rectifying the output of a winding 17. The sum of these voltages is applied to the control grid of the oscillator valve 1 via resistors 6 and 22 and a diode 21. The diode 21 then clips the positive peaks of the feed-back voltage from coil 4 at a level determined by the total control voltage so as to control the power supplied to the oscillatory circuit of the oscillator.

Filed: 1966-07-02
Abstract: 1,150,455. Tractor power lift mechanisms. IFA GETRIEBEWERKE BRANDENBURG VEB. 2 July, 1966, No. 29788/66. Heading A1P. The hydraulic pressure in the double acting jack 1 of a tractor power lift mechanism is kept substantially constant to operate a depth control arrangement, by means of a throttle point 3 hydraulically joining a working chamber of the jack with a small pressure accumulator 4. A pressure balancing piston 2 is placed across the throttle and has a depending lever 7 which operates the control valves 8 and 5. A slow increase in pressure in the jack cylinder is transmitted through the throttle to the accumulator and has no effect on the system. A sudden increase in pressure, however, is deflected by the throttle to operate the piston 2 which moves the control valves to release the pressure in the jack until the follow-up linkage 12, 20 and 9 returns the lever 7 to the neutral position. During a sudden decrease in pressure in the jack the accumulator has sufficient pressure to operate the piston 2 and thus control the jack pressure. A spring arrangement 10 and a piston 11 damp the movement of the follow-up linkage.
