Water demineralizing units

Claim 1

A WATER DEMINERALIZING SYSTEM COMPRISING: A DEMINERALIZING UNIT INCLUDING STRUCTURE DEFINING FIRST AND SECOND AND THIRD CHAMBERS AND PROVIDED WITH A FIRST DIAPHRAGM AS A COMMON WALL BETWEEN SAID FIRST AND SECOND CHAMBERS AND A SECOND DIAPHRAGM AS A COMMON WALL BETWEEN SAID FIRST AND THIRD CHAMBERS, A PORUS ION EXCHANGE BED ARRANGED IN SAID FIRST CHAMBER IN INTERPOSED RELATION WITH RESPECT TO SAID FIRST AND SECOND DIAPHRAGMS AND CHARACTERIZED BY BOTH CATION AND ANION EXCHANGE, AN ANODE IN SAID SECOND CHAMBER, AND A CATHODE IN SAID THIRD CHAMBER; AN INLET PIPE FOR CONTAINING A SUPPLY OF RAW WATER UNDER PRESSURE AND CONNECTED TO SAID FIRST CHAMBER; AN OUTLET PIPE FOR CONTAINING DEMINERALIZESD WATER UNDER PRESSURE AND CONNECTED TO SAID FIRST CHAMBER; VALVE MECHANISM FOR CONTROLLING THE FLOW OF DEMINERALIZED WATR FROM SAID OUTLET PIPE TO THE EXTERIOR AND THE FLOW OF RAW WATER FROM SAID INLET PIPE INTO SAID FIRST CHAMBER AND INTO CONTACT WITH SAID FIRST AND SECOND DIAPHRAGMS AND SAID BED; MEAND FOR OPENING AND FOR CLOSING SIAD VALVE MECHANISM; SAID BED BEING SO CONSTRUCTED AND ARRANGED THAT THE CATIONS AND THE ANIONS OF THE SALTS DISSOLVD IN TEH RAW WATER ARE QUICKLY EXCHANGED BY SAID BED RESPECTIVELY FOR HYDROGEN IONS AND HYDROXYL IONS CARRIED THEREBY IN ORDER QUICKLY TO DEMINERALIZE THE RAW WATER WITH THE RESULT THAT THE ION EXCHANGE CAPACITY OF SAID BED IS CORRESPONDINGLY REDUCED; A DRAIN PIPE; A FIRST CONDUIT FOR CONDUCTING A FIRST STREAM OF WATER AS AN ANOLYTE THROUGH SAID SECOND CHAMBER INTO CONTACT WITH SAID FIRST DIAPHRAGM AND SAID ANODE AND THENCE INTO SAID DRAIN PIPE; A SECOND CONDUIT FOR CONDUCTING A SECOND STREAM OF WATER AS A CATHOYLYTE THROUGH SAID THIRD CHAMBER INTO CONTACT WITH SAID SECOND DIAPHRAGM AND SAID CATHODE AND THENCE INTO SAID DRAIN PIPE; MEANS FORM CONDUCTING A DIRECT CURRENT FROM SAID ANODE TO SAID CATHODE THROUGH SAND FIRST AND SECOND DIAPHRAGMS AND THORUGH THE WATER IN SIAD FIRST AND SECOND AND THIRD CHAMBERS AND THROUGH SAID BED, WHEREBY SAID BED IS SUBJECTED TO ION REGENERATION IN THAT THE CATIONS AND THE ANIONS OF THE SALTS MEMTIONED CARRIED BY SAID BED ARE GRADUALLY RE-EXCHANGED FOR HYDROGEN IONS AND HYDROXYL IONS FROM THE WATER IN SAID FIRST CHAMBER AND SUBJECTED TO ELECTRODIALYSIS SO THAT THEY ARE TRANSPORTED RESPECTIVELY INTO SAID CATHOLYTE AND SAID ANOLYTE AND RESPECTIVELY CARRIED BY SAID SECOND AND FIRST STREAMS OF WATER INTO SAID DRAIN PIPE WITH THE RESULT THAT THE ION EXCHANGE CAPACITY OF SAID BED IS GRADUALLY INCREASED FOLLOWING CLOSING OF SAID VALVE MECHANISM; AND MEANS FOR EFFECTING LOCAL RECIRCULATION OF THE WATER IN SAID FIRST CHAMBER THROUGH SAID BED DURING REGENERATION THEREOF.
