Abstract: A chemical analyzer supplies a sample and a reagent into a reaction container provided with an opening mixes a fluid which is to be measured and contains the sample and reagent supplied into the reaction container, measures a property of the fluid in the reaction container, and controls the drive for the mixer. The mixer has a vertical drive machine to move the mixing tool up and down. The control unit controls the vertical drive machine to move the mixing tool up and down in the fluid to be measured in the reaction container so as to cause upward and downward flow of the fluid which is to be measured and is positioned below the mixing tool.

Abstract: An electric motor-driven kitchen appliance includes an electric motor and a gear stage. The electric motor includes a motor housing and the gear stage includes a gear case. The motor housing and gear stage are connected to each other by a bayonet lock. The electric motor and the gear stage are provided with the respective bayonet lock parts designed for the kitchen appliance.

Abstract: An apparatus for mixing powdered or premixed drywall joint compound and water to form a joint compound mixture or slurry includes a portable container rig with a container, pumping components, and mixing components on a dolly. A mixing element rests within the container upon the container bottom, while a mixing element driver assembly that is adapted to rest upon the upper lip portion of the container engages the mixing element and rotates it for mixing purposes while at the same time raising it slightly. The pumping components may include various commercially available valves and pump outlets that facilitate the filling of various tape application tools, and one preferred embodiment includes remote control components featuring automatic pump turnoff. One embodiment includes a multifunction coupling assembly having an upper coupling component and two different lower components.

Abstract: Apparatus for mixing ingredients in a receptacle includes a lid having an aperture which is positionable on the receptacle. A mixer shaft extends downwardly through the lid aperture and the shaft is movable relative to both the lid and to the receptacle to permit a mixer head connected to the shaft to move downwardly and upwardly within the receptacle after the lid has engaged the receptacle.

Abstract: Apparatus for use in processing radioactive waste materials for shipment and storage in solid form in a container is disclosed. The container includes a top, and an opening in the top which is smaller than the outer circumference of the container.The apparatus includes an enclosure into which the container is placed, solution feed apparatus for adding a solution containing radioactive waste materials into the container through the container opening, and at least one rotatable blade for blending the solution with a fixing agent such as cement or the like as the solution is added into the container.The blade is constructed so that it can pass through the opening in the top of the container. The rotational axis of the blade is displaced from the center of the blade so that after the blade passes through the opening, the blade and container can be adjusted so that one edge of the blade is adjacent the cylindrical wall of the container, to insure thorough mixing.
