DEFINITION

Classification: 73/861.354

Coriolis or gyroscopic:

(under subclass 861.351) Subject matter wherein (a) a conduit or impeller is rotated or oscillated to impose a transverse velocity gradient on the fluid or (b) a conduit is formed as a loop to provide an effective spin axis, the loop is rotated or oscillated about a drive axis and a gyroscopic couple is produced.
