Abstract
Abstract A chlorine generating apparatus is disclosed herein by which chlorine gas or sodium hyperchlorite is generated in small quantities from a brine solution economically enough to be practical for use in the backyard swimming pool. The apparatus includes a free standing unit and cell utilizing only salt as its raw material to generate the chlorine required. The chlorine generating cell incorporates a chemical pump for forciably urging the resulting product to the pool without the use of mechanical pumps or membranes. A device is included whereby hardness minerals are prevented from being deposited within the cell.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A chlorine generating device comprising; a tank containing a saturated solution of sodium chloride; an electrolytic cell submerged therein; said cell containing an ion selective membrane separating anode and cathode compartments such that a brine solution is present only on said anode compartment of said cell; a water softening means to supply hardness free water to make up said brine solution as well as to be directly supplied to said cathode compartment of said cell; and a source of direct current, the positive output thereof connected to an anode electrode of said cell and the negative output to a cathode electrode of said cell.
Claim 2
Dependent Claim
104 words
A chlorine generating device comprising; a tank containing a saturated solution of sodium chloride; an electrolytic cell submerged therein; said cell containing an ion selective membrane separating anode and cathode compartments such that a brine solution is present only on said anode compartment of said cell; a water softening means to supply hardness free water to make up said brine solution as well as to be directly supplied to said cathode compartment of said cell; and a source of direct current, the positive output thereof connected to an anode electrode of said cell and the negative output to a cathode electrode of said cell.
Claim 3
Dependent Claim
34 words
A chlorine generating device according to claim 1 wherein: said cell operates as its own pumping device by means of the gas generated therein causing the liquid from each chamber to be properly expelled.
Claim 4
Dependent Claim
43 words
A chlorine generating device according to claim 2 wherein: a check valve is incorporated at the input of either or both of said cathode or anode compartments of said cell to facilitate one way fluid flow in said pumping action of said cell.
