A multipurpose blower assembly for stimulating flows in underwater environments, which includes a lower assembly connecting to an upper assembly by a rotating shaft and a mount post for connecting the blower assembly to a supportive structure near a water body and supporting the lower assembly below and the upper assembly above the water body's surface. The lower assembly includes a lower bracket for supporting a blower motor, whereas the upper assembly includes a top plate for mounting an electrical gear motor having an output shaft connecting to the rotating shaft and a system controller having a microcontroller communicatively coupled to logic circuits for controlling operation of the electrical gear motor for rotation of the lower assembly relative to the upper assembly and a linear actuator to move upward and downward the lower bracket to effect angular positioning of the blower motor.

A liquid analyzing device includes a carrier, a driving unit, a rotating plate and a transmission mechanism. The driving unit is adapted to drive the carrier to rotate. The rotating plate is rotatably disposed on the carrier and adapted to support an analyzing cassette. The transmission mechanism is connected between the carrier and the rotating plate. When the driving unit drives the carrier to rotate to enable a rotation speed of the carrier to be changed and cross a predetermined rotation speed, the rotating plate rotates relatively to the carrier.

A stator operable to generate a rotating magnetic field for an electrical rotating machine, the stator comprising at least one circuit board with electrically conductive portions formed thereon, the electrically conductive portions connected with a multiphase configuration, wherein a phase comprises: on a first face of the circuit board(s) electrically conductive portions arranged as a plurality of elements, an element comprising a radially extending radial portion having: connected at a proximal end thereof a proximal portion, the proximal portion extending therefrom with a directional component in a first angular direction; and connected at a distal end thereof a distal portion, the distal portion extending therefrom with a directional component in a second opposed angular direction, whereby proximal and distal are defined relative the centre of rotation of the magnetic field and said angular direction is defined about said centre of rotation; and on a second face of the circuit board(s) electrically conductive portions comprising corresponding elements, whereby the proximal portion extends with a directional component in the second opposed angular direction and the distal portion extends with a directional component in the first angular direction.

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.

Provided is an ultra-dispersion mixer, for stirring a mixed material for producing a high-quality slurry for an electrode of a secondary battery within a short time by disposing a low-speed blade and a high-speed blade for stirring a mixed material in a chamber so as to easily and effectively disperse elements of the slurry of a secondary battery, supplied to a mixer during a procedure of preparing the slurry of a secondary battery produced by performing mixing procedures multiple times, and disposing blade parts having a plurality of stirring characteristics so as to realize various stirring characteristics in the mixed material on the high-speed blade to increase the dispersion of the mixed material while the mixed material circulates in a high-shear disperser of the chamber and to simultaneously increase the temperature of a supplied solution at the beginning of stirring of the mixed material in the chamber.

The invention relates to a dual centrifuge (10) which has the following: a driveshaft (16), a rotor (20), which is mounted on the driveshaft (16) and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (30); an opening (18) in the rotor (20), wherein an end region (16a) of the driveshaft (16) at least engages into said opening; and an additional drive mechanism (32) for the rotational unit or the rotational units (30). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor (20, 40, 50) can be arranged on the driveshaft (16) at all times. The various rotor types (40, 50) are also adapted to the additional drive mechanism (32) for the rotational units (30) such that the function is not adversely affected. The invention is characterized by a design for operating at least one angular head rotor (40) and a swing-out rotor (50). For this purpose, the driveshaft (16) and the various rotor types (40, 50) are adapted to each other. The bearing (16), the driveshaft (16), and the various rotor types (40, 50) are adapted to one another such that each non-dual rotor (40, 50) has a geometry that is measured such that when the rotor (40, 50) is mounted, a drive means (32a) of the additional drive mechanism (32) for the rotational units (30) is arranged so as to not contact the mounted rotor (40, 50).

A mixing device having a stirring element can include: a container for receiving fluids and/or solids; and at least one rotatable stirring element for mixing the fluids and/or solids; wherein the stirring element comprises a first bearing element and a second bearing element which are arranged at or near opposite ends of the stirring element; wherein the first bearing element is mounted on a first face of the container and the second bearing element is mounted on an opposite second face of the container; wherein the first bearing element comprises at least one non-permanently magnetized element such that it can be moved in rotation by externally induced reluctance forces, and wherein the second bearing element is mounted in a contactless manner by externally induced magnetic forces.

A method and system for converting a single-use liner lined bottom-mix mixing vessel to a single-use liner lined top-mix missing vessel.
