““There are probably exceptions to the rule that elements which are only alternatively used may not form a part of a true patentable combination and the syllabus of the decision, by the Board of Appeals in Ex parte Lasker, 31 U.S.P.Q. 341 , may be quoted as deciding the following: ‘While, as general proposition, claiming of elements which are only alternatively used may render claim aggregative, there are certain classes of mechanism which require for fulfillment of their purpose parts which are intended to be used alternatively, for instance types of typewriters, keys and reeds of organ, variable speed mechanism; alternatively-used parts contribute to unitary result and their inclusion in claim does not render it aggregative; same is true of tabulating machines and .auxiliary spacing machines.’ ””
