Abstract: A mixing head is created for mixing two plastic-forming components, having a mixing chamber and an ejection piston guided in a passage of the same cross section, in which, while retaining the mechanical self-clearing of the exit passage and mixing chamber by the eject piston and an intensive mixing of the reaction components, a quieting of the liquid component mixture after leaving the mixing chamber is achieved by providing a transversely movable choke member at the downstream end of the mixing chamber. When the choke member is in the choke position, one side of it situated in the exit passage forms a choke gap expanding diffuser-like toward the exit opening of the exit passage, and in a cleaning position, a cavity which it contains is brought into alignment with the exit passage, so that the eject piston can perform its passage clearing stroke.

Abstract: A special blending vessel lends itself to shifting from one continuously blended product to the next in a continuous flow with a sharp change so that there is substantially no mixing of the two products at the change over. There are two sets of ingredient inputs and product outputs for the blending vessel. And, there is a follower type divider that separates one set of ingredient inputs and product output from the other set. When a shift is to be made from the one product to the next, the ingredients of the second product are introduced and blended in the vessel while displacing the remainder of the one product without mixing therewith. Then the outputs are switched so that the second product follows with an abrupt change from the first product to the second.
