Abstract: Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved.

Abstract: Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved. In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor.

Abstract: An operative mechanism for use in combination with a rear view mirror assembly and which comprises: sealing housing parts forming an enclosure for component parts that are preassembled and include, a small reversible electric motor, screw threaded shaft and travel nut arrangement, together with a follower arm and pivot pin assembly received in operative engagement with each other within receptive and functional housing walls to provide a small, compact device for pivotal control and viewing adjustment of the rear view mirror.
