The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

An agitator assembly includes an agitator body, a shaft and a blocking part. The shaft is assembled to the agitator body and extends through a lead-through in the agitator body into the vessel, when assembled for use, and includes a sealing to seal the rotatable shaft. The blocking part arranged at the agitator body and including a shaft opening through which the shaft is arranged to extend, a mating surface to mate with the shaft which, when brought together by axial movement of the blocking part, provides a seal between the blocking part and the shaft, and the mating surface arranged at an axial distance from the sealing in the lead-through, and when brought together by the axial movement of the blocking part, provides a seal between the blocking part and the agitator body, and that the blocking part provides a closed space around the lead-through in the agitator body.

A module includes a housing, a sealing feature, a locking feature, and an agitator. The housing has an opening separating inner and outer surfaces and a boss that extends through the housing such that part of the outer surface forms an inner bore of the boss having a terminus pointing toward the opening. The agitator has a base, a shaft, and a mixing element coupled to the base such that the base, in cooperation with the sealing feature, circumferentially seals the opening of the housing to form a cavity defined by the inner surface. The shaft passes through the inner bore. The locking feature when engaged permits independent or simultaneous translational and rotational movement of the shaft while an area between the terminus of the boss and the shaft remains mechanically sealed during the movement against liquid or powder encroachment into a clean area of the inner bore.

The present invention relates to a dispenser for viscous materials that includes a static mixer, a first and second receptacle R.sub.1 and R.sub.2 for a first and second viscous material, connected in fluid communication with the static mixer, a first and second actuator configured for discharge of receptacle R.sub.1 and R.sub.2, an electrically or manually operable drive and a mechanical or hydraulic power transmission configured to translate drive motion into first and second actuator motion.

A blender assembly includes a blender jar having a bottom wall. The bottom wall includes first and second surfaces opposing one another and an interior edge defining an opening. A bearing housing is positioned at least partially within the opening and is spaced apart from the first surface of the bottom wall and the interior edge of the bottom wall. A nut is operably coupled with the bearing housing and is spaced apart from a second surface of the bottom wall. A gasket assembly is positioned to maintain a spacing of the bearing housing and the nut relative to the bottom wall. The gasket assembly is positioned over the interior edge of the bottom wall.

Chemical reactor with high speed rotary mixing, system thereof, and method thereof, for catalytic thermal conversion of organic (hydrocarbon-containing) materials (coal, plastics, rubber, plant matter, wood shavings, biomass, organic wastes) into diesel and other liquid fuels (automobile or/and jet engine fuels). Relevant to non-conventional commercial scale production of liquid fuels, and to commercial scale processing and disposing of organic waste materials. Chemical reactor includes: integrated combination of a reactor stationary assembly (RSA), having only stationary components remaining stationary during chemical reactor operation, and a reactor rotary mixing assembly (RRMA), having only rotatable components rotating during chemical reactor operation. May include anti-abrasion shield for shielding inner surface of reactor central housing from abrasion during chemical reactor operation. Rotor may include a reinforcement disc. Rotor blades or/and reinforcement disc may include rotor-based performance and process control structural features (openings, or/and protrusions, or/and depressions), for additionally controlling performance of the rotor.
