PANFILOV. 26 April, 1968, No. 14503/ 68. Heading A5R. Apparatus for treating the nervous system (e.g. for electronarcosis) by the action on the body of two medium frequency currents which produce in the body a combined low frequency current comprises two oscillation generators each having voltage and power amplifiers, there being a current regulator connected in the output circuits of the voltage amplifiers. As shown, the apparatus comprises two oscillators having transistors 1, 3 and 2, 4, the outputs from the oscillators passing to body electrodes 16 through voltage amplifiers with transistors 5 and 6 and through power amplifiers having transistors 9, 11 and 10, 12 and input and output transformers 7, 13 and 8, 14. Each oscillator includes a feedback circuit composed of resistors and capacitors 36, 38, 40, 42, 44 and 37, 39, 41, 43, 45, the resistors 36, 37 being adjustable so that the frequency output of each oscillator may be varied. Potentiometers 19, 20 allow the current outputs from the oscillators to be varied both independently and synchronously, the potentiometers including (Figure 2, not shown) an adjustment screw (26) at each potentiometer and an adjustment screw (21) on a cross-member 22 linking the two potentiometers. The apparatus also includes resistors 17, 18 said to be electrically equivalent to a patient and used for test purposes, a changeover switch 15 allowing the outputs from the oscillators to be applied to either the body electrodes 16 or the resistors 17, 18. Power is supplied to the oscillators from batteries or (using a changeover switch 34) an A.C. supply including a power transformer 29, rectifier 30, and a voltage stabilizing device comprising transistors 31, 32 and a Zenor diode 33. It is stated that in the event of the short circuiting of the electrodes the oscillators cease functioning and the voltage stabilizing device no longer supplies power to the oscillators. Milliammeters 46, 47 and a voltmeter 48 (rendered operative with a switch 49) are included.

Title: Fuel injection systems
IPC: F02M51/02
Filed: 1972-03-29
Abstract: 1373270 Electronic fuel injection systems for I C engines TSENTRALNY NAUCHNOISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT TOPLIVNOI APPARATURY  AVTOTRAKTORNYKH I STATSIONARNYKH DVIGATELEI and GORKOVSKY AUTOMOBILNY ZAVOD 29 March 1972 14599/72 Heading G1N In an I. C. engine, intermittent fuel injection system, electromagnetic injectors 5 supplied with pressurized fuel from a tank via a filter pump and reducing valve, are operated in synchronism with engine rotation by pulses provided by an electronic unit 7, the unit containing at least three multi-vibrators 12, 13, 14 one of which provides pulses having a duration dependent upon intake manifold pressure, another of which provides pulses for comparison, in respect of duration, with the first multi-vibrator pulses to determine fuel cut-off and the third of which provides pulses for comparison, in respect of duration, with the first multi-vibrator pulses to determine full power full enrichment. As shown, the multi-vibrators are triggered by pulses 19 of an engine speed transducer 8, and the durations of their pulses are compared in a logical unit 17. Multi-vibrator 12 provides pulses 20 having a duration dependent upon intake pressure (transducer 9), and multi-vibrators 14 and 13 provide pulses 21, 22 respectively, 21 having a duration dependent upon atmospheric pressure (transducer 10). During normal economical operation, the duration of pulses 20 is greater than the duration of pulses 21 and the unit 17 provides difference pulses 23 which are applied to an amplifier 18 and to a multi-vibrator 15 which then provides pulses 24 to the amplifier 18. The multi-vibrator 15 also triggers a multivibrator 16 which provides pulses 25, these however, being prevented from reaching the amplifier 18 by a trigger signal provided by the unit 17 due to the duration of pulses 22 being greater than that of pulses 20. Therefore, the injectors 5 are operated by pulses each having a duration which is the sum of the durations of pulses 23 and 24. When the duration of pulses 20 becomes less than the duration of pulses 21, no signal 23 is produced by unit 17 and no injection occurs. This occurs when the throttle valve is closed. When the duration of pulses 20 exceed the duration of pulses 22, the trigger signal provided by unit 17 changes level and allows the pulse 25 produced by multi-vibrator 16 to reach the amplifier. Each injection duration is then given by the sums of the durations of the pulses 23, 24 and 25. This occurs during full-power operation of the engine. The device 7 may be connected to other auxiliary transducers e.g. responsive to the temperature of induction air, cooling water and engine block. The multivibrator 13 may be connected to a transducer responsive to an engine condition.
