DEFINITION

Classification: 366/302

Having cooperating stationary element:

(under subclass 279) Subject matter wherein the mixing chamber has an immovable element therein which cooperates with the rotatable stirrer to effect or perfect agitation.

(1) Note. Included here is a stationary scraper, wiper, or brush for removing material from the stirrer.

164.4, for a stationary deflector in a mixing chamber having a rotating stirrer and specified feed means.

165.2, for a deflector in a mixing chamber, material being introduced into the chamber so as to cause rotary motion of the material therein.

171.1, for a rotating stirrer and cooperating stationary element in a mixing chamber including a liquid injector.

174.1+, for a stationary deflector in a mixing chamber having a liquid injector.

181.5, for a mixing chamber without a moving stirrer having specified feed means and in which material is mixed by flow past a stationary deflector. 181.7, for a mixing apparatus having plural feed means in which a stirrer and mixing chamber wall are separated by a small distance and cooperate to shear the material at a rate sufficient to mix the material.

253, for a rotatable stirrer mounted in a removable mixing chamber closure and cooperating with a stationary element.

264, for a centrifugal impeller with an outer stationary ring.

309+, for a rotatable stirrer in a mixing chamber and a movable scraper, wiper or brush for removing material from the chamber wall surface.

336+, for a flow-through mixing chamber without a moving stirrer having a stationary deflector for dividing and recombining material flowing through the mixing chamber.
