Abstract
A ground-free device for removing static charges from semi-conductive or conductive bodies. The device includes a storage capacitor, a conductive contact connected to the storage capacitor, and an air capacitor connected to the storage capacitor, in which a voltage below the breakdown voltage of the air is imposed on the air capacitor, e.g., by an RC-controlled transistor oscillator circuit. The device provides high efficiency removal of static charge, e.g., from the metallic bodies of cars and aircraft.

A ground-free device for removing static electrical charge from a conductive or semi-conductive body, comprising:
- a storage capacitor comprising first and second terminals;
- a conductive body contact means for establishing electrical contact with the body, and connected to the storage capacitor at a first terminal thereof;
- an air capacitor having first and second terminals, one of which is connected to the second terminal of the storage capacitor;
- and
- means for imposing on the air capacitor a voltage which is sufficient for effecting ionization of the air therein but is below the breakdown voltage of the air, and for keeping the circuit electrically open at the terminals of the air capacitor.
A ground-free device for removing static electrical charge from transportation vehicles, comprising:
- a storage capacitor comprising first and second terminals;
- a conductive body contact means for establishing electrical contact with the body, and connected to the storage capacitor at a first terminal thereof;
- an air capacitor having first and second terminals, one of which is connected to the second terminal of the storage capacitor;
- and
- means for imposing on the air capacitor a voltage which is sufficient for effecting ionization of the air therein but is below the breakdown voltage of the air, and for keeping the circuit electrically open at the terminals of the air capacitor.
A ground-free device for removing static electrical charge from a conductive or semi-conductive body, consisting essentially of:
- an electrical charge storage capacitor comprising first and second terminals, wherein the second terminal is constructed and arranged for direct exposure to an ambient air environment;
- and
- a conductive body contact means for establishing electrical contact with the body and connected to the storage capacitor at the first terminal thereof;
- whereby charge flowing from the conductive or semi-conductive body through the conductive body contact means to the electrical charge storage capacitor is dissipated to air of the ambient air environment at the second terminal of the storage capacitor.
