US Patent:

7764869, Jul 27, 2010

Filed:

May 24, 2006

Appl. No.:

11/420187

Inventors:

Nathan Harrison Noe - Calabasas CA, US
David A. Boyd - Pasadena CA, US

Assignee:

Lexington Environmental Technologies, Inc. - Mesa AZ

International Classification:

H05B 3/60
H05B 6/62

US Classification:

392322, 219772

Abstract:

Electrical oscillations are supplied to electrodes of a diathermal heating chamber. A liquid is passed through the diathermal heating chamber so as to be heated. The liquid has a minimum level of dissolved solids, which is replenished over time or when the dissolved solids in the liquid fall below a predetermined minimum level. Alternatively, when the level of dissolved solids is excessive, current input or liquid temperature is reduced.

International Classification:

H05B 3/60

US Classification:

392314

Abstract:

A method for generating heat includes passing a liquid between electrodes connected to an alternating current power supply. The liquid must have a sufficient level of electrolytes or dissolved minerals so as to be effectively heated. The level of current applied to the electrodes is preferably monitored and controlled. Exothermic, electrochemical reactions occur within the liquid and at the surface of the electrodes. More particularly, the electrodes are comprised of a material that can be oxidized, and the oxidation process during operation of the heater supplies additional current to heat the liquid.

Abstract:

A pipe corral connector consisting of a pair of bolts having corresponding hingedly coupled first ends, and second, threaded ends. The second end of one of the bolts is provided with a right hand thread while the second end of the other bolt is provided with a left hand thread. The threaded ends of the bolts are brought together with a nut that is internally threaded halfway with a right hand thread and halfway with a left hand thread. The nut provides a turnbuckle-like effect in bringing the two bolts together and tightly joining intersecting or parallel pipes of a pipe corral. The connector eliminates all sharp edges which might otherwise injure a corralled horse. The inside surface of the connector bolts may be serrated or notched to provide increased friction at the point of pipe connection. The nut and one of the bolts may be marked to identify matching thread sense to facilitate determination of the correct orientation of the nut.
