DEFINITION

Classification: 401/152

(under subclass 143) Implement wherein a wall or wall portion of the reservoir*, or of a chamber communicating with the reservoir*, is deformable and wherein the force-applying means comprises means for deforming the wall to reduce the effective capacity of the reservoir or chamber.

(1) Note. See Search This Class, Subclass note below for note concerning exclusion herefrom of a patent to an implement having a nonresilient permanently deformable flexible wall which is collapsed by direct digital engagement.

SEE OR SEARCH THIS CLASS, SUBCLASS:

143, for an implement including a reservoir whose flexible wall is deformed to increase the volume of the reservoir'' see (4) Note to subclass 143 concerning exclusion herefrom (subclass 152) of a patent to an implement having a nonresilient permanently deformable flexible wall which is collapsed by direct digital engagement..

145, for an implement in which a deformable member extends across an otherwise rigid-wall reservoir, deformation of which member produces the material-moving force.
