A mixer for mixing contents of a vessel includes a rotational mechanism with an attached gearbox. First and second shafts are coaxial with each other and attached to the gearbox. The gearbox is configured to rotate the first shaft and the second shaft in opposite directions. First and second rotors are rotated, respectively, in opposite directions by the first and second shafts. A housing encloses the gearbox and extends downward from the gearbox to just above the two contra-rotating first and second rotors (or impellers). The housing directs air (or other gas, liquid, or fluid) downward. Openings at the top of the housing admit air which is forced to the bottom of the housing by additional air impellers fastened to the outer of the two shafts. Lower housing openings allow aerated air to exit into desired material, such as fluid or solid/liquid mixture.

A blender including: a transmission base including a motor support, a motor shaft, a forward driver connected at a top of the motor shaft and a reverse driver rotating in opposite direction to the forward driver; a drive gear coaxially connected at a middle of the motor shaft; a reverse drive gear connected with the reverse driver; a reverse gear set for connecting the drive gear to the reverse drive gear arranged on the base; a blade device including a forward connector connected to the forward driver, a reverse connector connected to the reverse driver, a reverse blade shaft above the reverse connector, a forward blade shaft above the forward connector, the reverse blade shaft being provided with a central hole and connected with a reverse blade, the forward blade shaft being configured for passing through the central hole of the reverse blade shaft and connection with a forward blade.

In one example, a group of interchangeable supply modules to hold powdered build material for additive manufacturing. Each supply module in the group includes an exterior sized and shaped to fit into a mixer; an interior defining a non-circular mixing chamber, and an outlet through which powdered build material may leave the mixing chamber.

A powered surgical tool that includes a housing with a head and a handle that extends from the head. An electric motor is disposed in the head. A trigger extends from the handle. There is a void space in the handle. A plate separates the motor from the handle. Internal to the handle void space there is a rotor sensor and a control circuit. The rotor sensor is able to monitor the magnetic fields emitted by the motor rotor and that pass through the plate. The control circuit receives signals from the rotor sensor representative of the rotational orientation of the rotor and is further able to monitor the actuation of the trigger. Based on the rotor orientation signals and the actuation of the trigger, the control circuit generates signals that result in the selective generation of power signals to the motor rotor.

A method for mixing fluids in containers may include performing a mixing procedure on a plurality of containers on a container support, at least a portion of the plurality of containers being differently sized. The mixing procedure may include a plurality of mixing phases, wherein in each mixing phase the container support may be subjected to a mixing motion at a single rate for a period of time of about 5 seconds or longer, and wherein the single rate for at least one mixing phase of the plurality of mixing phases may differ from the single rate for at least one other mixing phase of the plurality of mixing phases. The mixing procedure also may include at least one non-mixing phase, wherein the container support may not be subjected to the mixing motion.

In the field of automatic analyzers, as items to be analyzed are increase, various reagents differing in such properties as liquid viscosity and contact angle are being used more frequently, and this trend is expected to continue. Also, reagents now take various forms (e.g., a concentrated reagent to be diluted by the water of an automatic analyzer), and so does dilution water. Such being the case, the invention provides an automatic analyzer capable of sufficient stirring regardless of items to be analyzed. To sufficiently stir a substance to which a reagent has been added, the automatic analyzer is designed to alter stirring conditions after a given amount of time has passed since the addition of that reagent.
