  • Device for electroanalgesia of patient's tissues
    Patent number: 4945910
    Abstract: A device for electroanalgesia of patients' tissues comprises series connected a generator (1) of asymmetric pulses some of which at the generator output have longer duration so as to provide electroanalgesia of the patient's tissues, while other pulses have shorter duration so as to provide depolarization of the patient's tissues, a current regulator (2) and a current stabilizer (3) to which are connected electrodes (4, 5) for connection directly to the patient and to a means for exerting a therapeutic effect upon the patient.
    Type: Grant
    Filed: November 2, 1988

  • Device for arcless switching of electrical circuits
    Patent number: 4885654
    Abstract: A device for arcless switching of electrical circuits, wherein power leads of a controlled semiconductor device - transistor 9 are connected parallel to a movable contact (2) and a fixed make contact (3) of a make-and-break contact assembly (1). A control lead of the transistor, which is its base, is connected to a resistor (11) and a fixed break contact (10) of the contact assembly (1), which are components of a control circuit. The movable contact (2) and the resistor (11) are connected to opposite poles of the supply source.
