Abstract: A discharge device for discharging electrostatic charges from a shaft includes a frame support having a first leg and a second leg and a contact strand for forming a contact surface with the shaft, a first end of the contact strand being clamped on the first leg and a second end of the contact strand being mounted so as to be displaceable on the second leg, a receiving means which is disposed on the frame support, the second end of the contact strand extending at least partly into the receiving means, and a switch, in particular a reed switch, which is disposed in the receiving means or in the contact strand and which is configured so as to be activated as a result of a displacement of the second end of the contact strand, said second end extending at least partly into the receiving means.

Abstract: The invention relates to a discharge device (1) for discharging electrostatic charges from a shaft (20), the discharge device (1) having a frame support (2) having a first leg (3) and a second leg (4) and a contact strand (6) for forming a contact surface with the shaft (20), a first end (7) of the contact strand (6) being clamped on the first leg (3) and a second end (8) of the contact strand (6) being mounted so as to be displaceable on the second leg (4), a receiving means (10) which is disposed on the frame support (2), the second end (8) of the contact strand (6) extending at least partly into the receiving means (10), and a switch, in particular a reed switch (12), which is disposed in the receiving means (10) or in the contact strand (6) and which is configured so as to be activated as a result of a displacement of the second end (8) of the contact strand (6), said second end (8) extending at least partly into the receiving means (10).

Abstract: The invention relates to a discharge device (10) for discharging electro-static charges from a shaft (39), comprising an annular holder (11) and a conductor arrangement (12), said conductor arrangement comprising at least one flexurally elastic conductor (13) arranged on the holder, said conductor being made of a carbon fiber arrangement, each end of the conductor being accommodated in the holder, said conductor arrangement comprising at least two conductor portions (33) extending transversely to a longitudinal shaft axis (32), said conductor portions each comprising a shaft contact portion (34) which together form a contact arrangement for being contacted with two circumferential contact areas of a shaft circumference (35), which are arranged in a shaft contact plane W, in such a manner that the shaft contact portions are arranged tangentially to the shaft circumference upon contact to the shaft circumference.

Abstract: The present invention is a method and apparatus for electrocuting pests such as gophers, rats and the like. The present invention employs a resistive switch that uses the same electrodes to sense the presence of a pest therebetween as are used to electrocute the pest. The resistive switch senses a leakage current flowing through the pest and into the reference electrode of its electronic circuit and uses the presence of this current to trigger the generation of a high voltage and current that is of sufficient magnitude to dispatch the pest. A timer deactivates the generator after a predetermined time has elapsed to save battery power. A status indicator is provided that does not consume power unless activated by a user. The invention will not retrigger until reset by turning it off and then on again, thereby activating the power on reset circuit.
