(under the class definition) Process or apparatus comprising steps or means which are peculiar to forming boreholes in naturally situated bodies of frozen water.
(1) Note. A specific disclosure of use in boring ice is sufficient to cause classification in this subclass.
(2) Note. The term "naturally situated bodies", is limited to bodies of the type which are normally occurring earth structures such as glaciers or ponds. If the subject matter is limited by disclosure to bodies which do not meet this limitation, or the bodies are portions of naturally situated bodies which have been removed, classification will be in another class.
