Apparatus for mixing a powdered material with a liquid that includes a housing, in which a working space having an inner wall is arranged and a rotatably-driven rotor being arranged in the working space. The rotatably-driven rotor includes a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor. The apparatus also includes a feed opening for the powdered material being arranged above the blade ring and an annular gap connectable to a liquid supply arrangement being arranged below the blade ring, in a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another.

A mixing tool has an elongated tubular conduit with a flattened portion at a lower end, a garden hose fitting joined to an upper end, a mixing blade having one or more horizontal wings, a tapered lower end, and an extension at an upper end inserted into the flattened portion and fastened through walls of the flattened portion, and two opposing, horizontal hand grips joined to the elongated tubular conduit at a position closer to the garden hose fitting than to the mixing blade. A user is enabled to prepare a pourable concrete mix by inserting the mixing blade into a quantity of dry ingredients, connecting a garden hose, causing water to flow through the elongated tubular conduit, around the mixing blade extension, into the dry ingredients, and turning the mixing blade by manipulating the opposing horizontal handgrips, to mix the moistened dry ingredients into the pourable concrete mix.

Bone cement applicators and methods for application of a bone cement dough, the applicators and methods comprise a tubular cartridge with an internal space, a dispensing plunger for expelling the starting components through an opening of the cartridge opposite from the dispensing plunger, wherein the dispensing plunger is mobile in longitudinal direction in the internal space of the cartridge. The applicators and methods further comprise a hose, an application opening, a three-way valve operable from outside and arranged or arrangeable in the hose or on a side of the hose facing the cartridge, and a collecting container arranged on the three-way valve. The three-way valve is designed and arranged or arrangeable in the applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the cartridge and closes a feed-through to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the cartridge.

A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. Heaters are mounted within the mixing chamber for drying blend material in the mixing chamber.

A liquid mixing system includes a support housing at least partially bounding a compartment. A mount is secured to the support housing. A drive motor assembly is configured to engage a drive shaft for moving the drive shaft within the compartment of the support housing. A four bar linkage system extends between the mount and the drive motor assembly, the four bar linkage system being movable between a first position wherein the drive motor assembly is disposed at a first elevation and a second position wherein the drive motor assembly is disposed at a second elevation that is different from the first elevation.

In a sludge thickener water/wastewater treatment system, sludge solids are recirculated with a mixer positioned in the influent column or offset from the center column and within the stilling well, in order to produce essentially constant sludge solids concentration in the sludge withdrawn from the thickener. This solves the problem of thickeners producing inconsistent underflow solids concentration and often exhibiting problems with binding of rake arms due to sometimes very high sludge concentrations. Also, dewatering steps that follow thickening typically require a relatively constant solids concentration for efficient operation.

A blending machine, for homogenizing materials deposited within an intermediate bulk container (IBC), includes: a frame; a drive motor; a clamp disk rotatably supported by the frame and coupled to the drive motor to drive disk rotation; first and second jaw clamps movably mounted to the frame; and a drive mechanism to drive the jaw clamps to translate toward each other and rotatably secure the IBC's boom to the rotatable clamp disk. A clutch, a torque limiter, and a limit switch limit the pressure applied by the clamps, and the extent of their travel to optimize clamping and rotatability. The blending machine is moveably mounted to a pedestal, and elevated by an actuator. A blending bar within the IBC is coupled through the boom to the clamp disk, and driven to rotate to blend the materials, in addition to mixing by rotation of the ICB.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a fluid medium and a saccharifying agent.
