Filed:

Nov 19, 1979

Appl. No.:

6/095625

International Classification:

C02F 148

US Classification:

210695

Abstract:

Method and apparatus for magnetically treating aqueous and non-aqueous liquid streams to enhance their flow properties and to reduce their tendency to deposit scales, encrustations and the like, wherein the liquid stream for treatment, either immediately prior to or substantially simultaneously with its traversal of a high density, magnetic flux field having a normal orientation with respect to the primary flow path of the liquid stream is deflected along secondary flow paths angularly displaced from the primary flow path causing in effect a high velocity, essentially shear angle traversal of the flux field by said stream. Apparatus therefor includes a plurality of permanent magnet groups arranged in parallel within a hollow casing or housing, each of said groups comprising a plurality of superposed, elongated magnets in registered, overlying relationship polarized along their longitudinal axis, the latter being parallel to the primary flow path, the adjacent magnet groups providing liquid passageways therebetween and generating magnetic flux paths essentially normal to the primary flow path.

Abstract:

An energy saving control circuit for a water heater having a hot water storage tank provided with an electrically operated heater, i. e. , an electric heater or an electrically controlled combustion burner, includes a water flow detection device associated with either the cold water inlet or hot water outlet of the tank for sensing the flow of water into or out of the tank and arranged to energize the heater upon detection of water flow indicative of the withdrawal of water from the tank. A holding circuit maintains the heater energized, even though the flow of water ceases, until such time as a thermostatic switch responsive to the temperature of the water in the tank disables the holding circuit and deenergizes the heater upon the water stored in the tank attaining a predetermined desired temperature. The heater remains deenergized notwithstanding the demand for heat by the thermostatic switch until such time as the water flow detector once more detects the withdrawal of hot water from the tank and the cycle of operation is repeated. Thus two interdependent conditions must simultaneously obtain for heater energization, i. e.
