Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
THE METHOD OF CONTROLLING THE RELATIVE HUMIDITY OF A LIQUID DRY CLEANING SOLUTION IN A DRY CLEANING SYSTEM WHICH COMPRISES SPARYING DRY CLEANING SOLUTION CONTINUOUSLY INTO AN AIR TIGHT CHAMBER AND THEREBY CREATING AN ATMOSPHERE OF VAPOR FROM SAID SOLUTION IN SAID CHAMBER, CONTINUOUSLY REMOVING THE DRY CLEANING SOLUTION FROM SAID AIR TIGHT CHAMBER, CONTINUOUSLY MEASURING THE RELATIVE HUMIDITY OF THE VAPOR IN SAID CHAMBER, AND ADDING WATER TO THE DRY CLEANING SOLUTION AS IT IS SPRAYED INTO SAID CHAMBER WHEN THE RELATIVE HUMIDITY IS BELOW A PREDETERMINED AMOUNT.
Claim 2
Independent Claim
89 words
THE METHOD OF CONTROLLING THE RELATIVE HUMIDITY OF A LIQUID DRY CLEANING SOLUTION IN A DRY CLEANING SYSTEM WHICH COMPRISES SPARYING DRY CLEANING SOLUTION CONTINUOUSLY INTO AN AIR TIGHT CHAMBER AND THEREBY CREATING AN ATMOSPHERE OF VAPOR FROM SAID SOLUTION IN SAID CHAMBER, CONTINUOUSLY REMOVING THE DRY CLEANING SOLUTION FROM SAID AIR TIGHT CHAMBER, CONTINUOUSLY MEASURING THE RELATIVE HUMIDITY OF THE VAPOR IN SAID CHAMBER, AND ADDING WATER TO THE DRY CLEANING SOLUTION AS IT IS SPRAYED INTO SAID CHAMBER WHEN THE RELATIVE HUMIDITY IS BELOW A PREDETERMINED AMOUNT.
Claim 3
Dependent Claim
124 words
IN AN APPARATUS FOR CONTROLLING THE RELATIVE HUMIDITY OF A LIQUID DRY CLEANING SOLUTION, THE COMBINATION COMPRISING A DRY CLEANING SYSTEM THROUGH WHICH SAID LIQUID SOLUTION IS CIRCULATED, AN AIR TIGHT CHAMBER, SAID CHAMBER HAVING AN INLET THROUGH WHICH A PORTION OF SAID LIQUID SOLUTION IS CONTINUOUSLY INTRODUCED INTO SAID CHAMBER AND AN OUTLET THROUGH WHICH SAID LIQUID SOLUTION IS REMOVED FROM SAID CHAMBER, A SENSING DEVICE INCLUDING A SENSING ELEMENT POSITIONED IN SAID CHAMBER, SPRAY MEANS IN SAID INLET OF SAID CHAMBER FOR CREATING AN ATMOSPHERE OF VAPOR FROM SAID LIQUID SOLUTION AS IT IS INTRODUCED THROUGH SAID INLET INTO SAID CHAMBER, AND MEANS ACTUATED BY THE SENSING DEVICE FOR ADDING WATER TO THE DRY CLEANING SYSTEM AT SAID INLET TO SAID CHAMBER.
Claim 4
Dependent Claim
