Abstract: A chlorine generator (1) includes an electrolytic cell (2) and a transformer/rectifier unit (4). The electrolytic cell (2) has an anode (6) provided with a hood (7) and a cathode (8) located near the top of the cell (2). A conduct (11) connected to the top of the anode hood (7) has an outlet to the water (5) surrounding the cell (2). A saline anolyte (24) is provided near the anode (6) and a dilute saline catholyte (25) is joined in the region of the cathode (8). When the power supply is switched on gas (27) and caustic soda are formed at the cathode (8). Gas (28) consisting of chlorine and traces of oxygen is formed on the anode (6) by electrolysis.

Abstract: The present invention provides a pharmaceutical composition, primarily for the treatment of inflammatory conditions, including benign prostata hypertrophy, the composition containing a spiroketalin such as diosgenyl-.beta.-D-glycoside or hecogenyl-.beta.-D-glycoside. A unit dosage form is provided which contains between 0,3 and 0,75 mgm of the spiroketalin.

Abstract: The invention is concerned with new chemical compounds being the hemiesters of steryl glycosides, methods of preparing these hemiesters, and pharmaceutically, particularly anti-inflammatory, compositions containing the new hemiesters.

Abstract: Sterol glycosides and esters thereof with monocarboxylic acids of natural or synthetic origin are used to combat human and animal illness in dosages of not over 10 mg per day.

Abstract: Plant material derived from the family Hypoxidaceae is heated at a temperature of at least 60.degree. C. for a sufficient period to ensure enzyme destruction and is then extracted at a temperature of 0.degree.-30.degree. C. with aqueous alcohol containing 30-75 volume percent ethanol for about 1 to 15 days to obtain a pharmaceutically active material.
