1BARRIER OPENING WITH FLEXIBLE SEAL FOR OPERATOR


DEFINITION

Classification: 312/1

(under the class definition) Apparatus including an opening in a barrier and flexible means mounted at the opening and entirely closing it or sealing against an operating member, e.g., hand, between opposite sides of the barrier thus allowing an operator to manipulate an object on the distal side of the barrier without leakage of fluid through the opening.

(1) Note. This subclass is the residual home of the defined structure. Many classes contain patents to such structures combined with art features; e.g., surgical devices; work handling; specific machines as abrading, washing, drying, welding, etc. Such patents are classified in the appropriate art class. Exemplary instances are noted under "SEARCH CLASS".
