DEFINITION

Classification: 264/180

(under subclass 178) Processes in which the liquid of said forming or receiving bath is in motion.

(1) Note. Incidental disturbance or movement of the liquid which may occur by the unconfined passage of a formed article therethrough is not sufficient to place a patent in this subclass. However, disclosure that the formed article in passing through a restricted tube placed in the bath whereby a current of liquid is created and carried therethrough by frictional contact with the formed article, is within the scope of this subclass.
