Abstract

An apparatus and method for positioning each of the many silver electrodes into the tank of water such that arcing does not occur. This consists of a light or electromagnetic detector held in the tank of water so as to be close to the point where the silver electrode comes in contact with the water. When the silver electrode comes close enough to the water that an electrical arc occurs the detector observes this and sends a signal to the motor control. This signal is in turn sent to the motor causing it to turn. This turning action causes the treaded male rod to turn and it moves toward the water. As it moves downward it in turn lowers the silver electrode down until it comes close enough to the water that the arcing stops. When the arcing stops then the signal to the motor stops and the motor stops turning.

Claims

1. An apparatus for determining if an electric arc is occurring and repositioning the silver electrode so that the arcing stops, said apparatus comprising:

at least one silver electrode made of silver element holding means for holding the end of the silver electrode, within 0.5 inch of the free upper surface of the fluid, power means for conveying electrical power to this electrode from a transformer.

2. The apparatus of claim 1:

The apparatus of claim 1, wherein the electrode holding member comprises an electrically conductive, male threaded cylindrical member, and wherein the positioning means comprises an electrically conductive female-threaded member fixedly secured to the lid within the hole formed in the lid and wherein the male-threaded cylindrical member is threadably engaged within the female-threaded cylindrical member in the first rotational direction operates to move said male-threaded cylindrical member downwardly, and rotating the male threaded cylindrical member in a second, opposing rotation direction operates to move said male-threaded cylindrical member upwardly.

3. The apparatus in claim 1, for transferring the rotational power from the gear motor to the male threaded cylindrical member with out conducting electricity from this male-threaded member to the motor.

4. The apparatus in claim 3, consisting of a plastic, cylindrical, hollow, slotted rod which fits over the male-threaded member.

5. The apparatus in claim 4, consists of a pin which goes through the male-threaded member and fits into the slots on the plastic, cylindrical, hollow, slotted rod. This locks the male-threaded threaded member to the plastic, cylindrical, hollow, slotted rod so that they turn together.

6. The apparatus in claim 1, wherein the motor turns, it in turn causes the plastic, cylindrical, hollow, slotted rod to turn. The pin transfers power to the male-threaded member causing it to turn.

7. The apparatus in claim 6, whereas the male-threaded member turns, it lowers itself down and in turn lowers the silver electrode toward the solution.

8. The apparatus in claim 7, consists of the silver electrode.

9. The apparatus in claim 8, comes near the solution then an electric arc occurres.

10. The apparatus in claim 9, wherein the detector observes this arc and sends a signal to the motor control.
