Abstract: Disclosed in a filter for filtering a working fluid comprising a canister having an inlet and an outlet; a first partially perforated generally conical member positioned in said canister; a second generally conical member positioned inside said first partially perforated generally conical member, whereby the working fluid upon entering the inlet is caused to spin inside the canister, to pass through the perforated portion of the first generally conical member, to enter an inlet to the second generally conical member, to spin within the second conical member and to pass through the outlet.

Abstract: A method for treating patients suffering from left ventricular dysfunction is disclosed. The method involves applying, during diastole, for a time period of about one hour, at least five days each week for at least about six weeks, an incrementally increasing external therapeutic pressure sequentially to the patients' lower extremities from first the calves, then the thighs and last the buttocks. The initial hourly treatments are carried out at a peak diastolic/systolic pressure ratio (D/S Ratio) in the range of about 0.4:1 up to about 0.9:1, depending on the patient's left ventricular ejection fraction. The D/S Ratio is increased slightly during the next set of hourly treatments, the D/S Ratio is again increased slightly during the next following set of hourly treatments, the D/S Ratio is again increased slightly during the next set of hourly treatments, and finally the D/S Ratio is increased slightly and maintained during the remaining set of hourly treatments.

Abstract: An improved assembly of bipolar electrode elements for use in the electrochemical preparation of hypochlorites or chlorine from dilute water solutions of chlorides, particularly mildly saline swimming pool water, is described. The end of each bipolar electrode element is enclosed in a nonconductive plastic strip, and guard baffles of corresponding thickness and height are inserted on each side of the bipolar electrode. A desired number of these elements are grouped and cemented together by solvent welding. Special adhesives enhance the sealing of the bipolar electrodes. With this electrode assembly, the deposition of mineral deposits on the electrode surfaces can be minimized by reversing the flow of direct current as often as twice a day or as seldom as once every two weeks.

Abstract: Bipolar cells are designed to permit the introduction of full wave, half wave, or time proportioned, rectified and unfiltered current into a special electrolysis zone which contains coated titanium anodes and steel cathodes with nonconducting baffles which protrude beyond each bipolar electrode in water containing dilute salt solutions. Thereby voltage transformers are eliminated and amperages are very much decreased and easily controlled. For the chlorination of swimming pools, all of the filtered pool water is passed directly through the bipolar electrodes at velocities between 3 and 6 feet per second. This direct liquid flow combined with time proportioned electric current and with iron or stainless steel cathodes prevents the accumulation of precipitates in the cell and permits the control of a wide range of chlorine concentrations while prolonging the life of the coated anodes.
