Abstract
A voltmeter for measuring atmospheric or other voltages eliminates the dead band without application of high voltages or radioactive isotopes to increase conductivity in the region of the probe. A vacuum tube is operated at substantially reduced conduction in order to achieve high sensitivity and eliminate passive components in the input circuit. A voltage is developed to produce meter indication or control charging or charge-neutralizing circuits. In the preferred embodiment, a meter scale is calibrated to indicate the presence of atmospheric charges of particular interest to anglers. Naturally occurring electrical currents are known to stimulate the feeding of fish.
Claims9
A non-contact voltage amplifying circuit comprising an antenna and an earth ground, whereby earth's atmospheric voltages are measured, informing anglers to the presence of conditions conducive to the natural stimulation of fish feeding the non-contact voltage amplifying circuit further comprising:
- a source of power;
- a transformer engaged to the power source;
- an on/off switch engaged between the power source and transformer;
- a terminal strip;
- an antenna engaged to an input terminal of the terminal strip;
- an earth ground engaged to a ground terminal of the terminal strip;
- a space charge tube comprising a plurality of grids and a plate;
- the input terminal of the terminal strip being engaged to one grid of the tube;
- a meter engaged to the plate of the space charge tube;
- a gas discharge tube engaged to an input of the tube;
- the tube at a substantially reduced cathode temperature and electron emission, whereby voltages or other related quantities or qualities are measured in real time using only the naturally occurring voltage and conductivity present as a grid control source.
