A drive mechanism for transposition and stirring by single disc single motor includes a rotating transposition disc, wherein the transposition disc is a single-layer transposition disc, at least one gear set in which a gear ring is engaged with a planetary gear is arranged successively from inside to outside with the rotating shaft of the single-layer transposition disc as the center, the gear ring of each gear set is fixed on a rack, and the planetary gear engaged with the gear ring is rotationally installed on the transposition disc to serve as a driving gear of a stirring shaft of a color matching paint bucket. By adoption of the above technical solution, the present invention has the following beneficial effects: the structure is reasonable, the parts and components of the color mixing machine are reduced without reducing and decreasing the functions of the color mixing machine.

An automatic analyzing apparatus includes a stirring mechanism. The stirring mechanism is provided with: a fixed member fixed to an apparatus body; a motor attached to the fixed member; a drive-side helical gear provided on a drive shaft of the motor; bearings provided to the fixed member with the center shaft held parallel to the drive shaft of the motor; a support member of circular column shape, supported so as to be capable of receding from one side relative to the bearings; a driven-side helical gear fixed to an end of the support member coaxially with respect to the support member such that the driven-side helical gear is fitted together with the drive-side helical gear with the support member recessed into the bearings; and a stirring rod extending coaxially with the support member from the end of the support member opposite to the end provided with the driven-side helical gear.

Systems and methods for providing and using a bone cement mixer are described. While the systems can include any suitable component, in some cases, they include a container that is configured to hold an amount of bone cement, a drive shaft coupled to the container, a mixing arm that is coupled to the container and configured to mix the bone cement when the bone cement is disposed within the container, and a vacuum pump configured to draw gas from within the container to form at least a partial vacuum within the container. In some cases, the drive shaft is mechanically coupled to the mixing arm and the vacuum pump such that rotation of the drive shaft forces the mixing arm to move and the vacuum pump to be actuated. Other implementations are also described.

An apparatus (10) for producing an orbital movement in a plane (20) is disclosed. The apparatus (10) comprises a lower shaft (40) and an upper shaft (30), being parallelly and eccentrically attached to one another, and a platform (50) mounted on the upper shaft (30). A ring gear (60) is attached to the platform (50) and coaxially rotatable about the upper shaft (30). A gear wheel (80) is coaxially rotatably mounted on the lower shaft (40) and engages with the ring gear (60).

A vertical motion mixer has a drive mechanism with two axes of guidance for vertical motion. A reciprocating yoke is fixedly secured to the driving shaft for the mixer, without any guide bearing for the mixer driving shaft. The mixer drive unit is of compact and simplified design with minimal moving parts, and including drive gearing with planetary gears to minimize wear during reciprocating movement.

Disclosed herein is a water treatment system. The system comprises a mixing station in which coagulant is mixed into water for treatment in the system. The system comprises a floccule accumulation station in which the building of floccules in the water/coagulant mixture is promoted. The system comprises a settlement station in which the floccules are allowed to settle. The mixing station, floccule accumulation station and settlement station comprise one or more reservoirs, wherein at least one of the one or more reservoirs is an intermediate bulk container.

A bearing assembly for a blender jar assembly includes a blender jar having a bottom wall that defines an opening. A retainer is positioned within the blender jar and defines a receiving space in communication with the opening. A jar collar is positioned exterior of the blender jar and is operably coupled with the retainer. A bearing housing is positioned within the receiving space and is spaced apart from the retainer by a first spacing. A nut is operably coupled with the bearing housing and is at least partially received by the receiving space. The nut is spaced apart from the retainer by a second spacing. A gasket is positioned to maintain at least one of the first and second spacings of the bearing housing and the nut relative to the retainer.

The present invention relates to a kind of pigment preparation, in particular to a modified layered silicate novel barrier and shielding pigment and its preparation method. It is a layer silicate with exchangeable anticorrosive ions as a template, using metal oxides or metal salts, inorganic acids to synthesize nano-spherical zinc phosphate, phosphate, molybdate, borate or tungstate, with rare earth cerium, strontium, lanthanum or praseodymium doped modification of the pigment. The invention uses silicate as a template to effectively control the agglomeration of nanoparticles during the liquid phase deposition process, avoiding the multiple cleaning and sewage treatment processes required by using surfactants and solvents. What is more valuable is lamellar silicic acid. The salt itself has certain anti-corrosion properties and is economical. At the same time, the physical barrier and exchangeable anti-corrosion ions of the lamellae further improve the anti-corrosion properties of the pigment, making the pigment highly active and shielding.

A contrast agent mixer (100) for providing a foam type contrast agent is presented. The mixer (100) comprises a holding arrangement (109) for supporting a mixing container, a substantially homogeneous circular mixer blade (110) for mixing a contrast powder with a liquid in the mixing container (200), and a controller configured to control a rotational speed of the mixer blade (110) and a vertical distance (D) between the holding arrangement (109) and the mixer blade (110). A method, a system and a mixing container are also presented.

A liquid polymer dosing and mixing chamber and pump having a pump housing, a mixing reactor, a spacing cup, an actuator, a drive shaft, a drive shaft coupling unit, and a progressive cavity pump adapted to create doses of a first substance and to mix it with one or more substances introduced into the mixing reactor via one or more inlets.
