(1) Note. Included with patents claiming filling with both liquids and gas are those subcombinations relating to filling with one or the other but including such limitations as to restrict the utility of the subcombination to devices in which filling with the other of the two materials is a necessary accompaniment.
(2) Note. Tire inflation with gas alone is not specifically provided for in this schedule but the patents relating to the combination with the source of supply of the inflating fluids have been distributed in appropriate subclasses according to the means for causing the connection to be made, the means for supporting one or the other of the supply and receiver elements in relation to the other and similar relationship provided for in this class.
(3) Note. Tire or tube deflation accomplished by evacuation apparatus where other necessary characteristics of this class are present, are included in subclass 65.
