A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, includes: a wetting chamber, a chamber for grinding and discharging the dispersed polymer with a horizontal axis of revolution, and a mechanism for connecting the wetting chamber to the grinding chamber in the form of an L-shaped tube. The upper and lower parts of the wetting chamber and the L-shaped tube have an internal surface with an identical surface tension (TS1). The cover of the wetting chamber has an internal surface with a surface tension (TS2) higher than the surface tension (TS1) of the internal surface of the upper and lower parts of the wetting chamber and the L-shaped tube.

A mixing system includes a container having an encircling sidewall bounding a chamber and extending between an upper end and an opposing lower end; a support plate disposed within the chamber and secured to the encircling sidewall; an inner wall secured to the support plate and projecting within the chamber toward the upper end, an open space being formed between the inner wall and the encircling sidewall; and a first aperture extending through the encircling sidewall so as to communicate with the open space. A mixing assembly is positioned within the container and is supported on the support plate, the mixing assembly including a pliable enclosure and a mixing device.

The invention discloses a method for predicting the solubility of at least one species at a specified pH value in an aqueous buffer comprising at least one weak acid species and/or at least one weak base species. The method comprises the steps of: a) selecting a start composition of the buffer, giving a start value for the total solute concentration; b) calculating the concentrations of all ionic species present in the buffer at the specified pH value from the total composition of the buffer and available dissociation constants; c) calculating the solubility limits of each combination of ionic species present in the buffer from available solubility products, taking the concentrations calculated in step a) into account; d) comparing the concentrations of all ionic species calculated in step a) with the solubility limits calculated in step b) and determining if any solubility limit is exceeded; e) if no solubility limit is exceeded, increasing the total solute concentration of the buffer or, if at least one solubility limit is exceeded, decreasing the total solute concentration of the buffer, and; f) repeating steps b)-e) until a predetermined convergence criteria is met.

A baby bottle blender includes a baby bottle having a top collar with external threads and a bottom collar with external threads. A nipple has an anti-colic air vent. The nipple cap is internally threaded to be removable threaded onto the top collar of the baby bottle and holds the nipple extending through a central aperture of the nipple cap onto the top collar. A top cover snaps over the nipple cap and covers the nipple. An agitating unit is centrally retained within a bottom attaching cap of the baby bottle. Next, a base member has a top recess to engage with the agitating unit in the bottom attaching cap on the baby bottle. An electrical mechanism in the base member is for operating the agitating unit, so that the agitating unit will mix formula within a liquid placed through the top collar of the baby bottle in approximately seven (7) seconds to thoroughly blend the formula.

This fine particle production method involves a dissolving step in which a stirrer having a rotating stirring blade is used to dissolve at least one type of fine particle raw material in a solvent to obtain a fine particle raw material solution, and a precipitation step in which the fine particle raw material solution and at least one type of precipitation solvent for precipitating the fine particle raw material from the fine particle raw material solution are introduced between at least two treatment surfaces which are arranged oppositely one another, can move closer to and farther apart from one another, and at least one of which can rotate relative to the other, and the fine particle raw material solution and the at least one type of precipitation solvent are mixed in a thin film fluid formed between the at least two treatment surfaces, and the fine particles are precipitated. The stirring energy is determined by the stirring time conditions of the stirrer, the circumferential velocity conditions of the stirring blade, and the temperature conditions of the fine particle raw material solution, and in the dissolving step, the stirring energy is varied by changing at least one of the aforementioned conditions, and by changing the stirring energy, the degree of crystallization and the crystal form of the fine particles obtained in the precipitation step are controlled.

A ballast water treatment system includes: a chemical agent container for containing a chemical agent for a ballast water treatment; a chemical liquid preparation tank having a tank main body for containing the chemical agent supplied from the chemical agent container and water for dissolving the chemical agent, and a mixture part for mixing the chemical agent with the water in the tank main body; a chemical liquid storage tank for storing the chemical liquid obtained by dissolving the chemical agent in the water in the chemical liquid preparation tank; and a chemical liquid supply part for supplying the chemical liquid stored in the chemical liquid storage tank into ballast water.

A device for mechanical fragmentation of tissues facilitates preparation of the composition of isolated cells from a tissue sample, the preparation including mechanical fragmentation of the tissue, the device including a motorized support and a container, the motorized support including a motor having a rotor secured to a coupling member, the container internally including a rotary shaft with radial arms sweeping the inside of the container as the shaft rotates, the motorized support and the container including a complementary securing unit that allow the container to be immobilized on the motorized support, the coupling member and the rotary shaft being configured in such a way as to allow axial rotation of the rotary shaft when the rotor of the motor is turning. The radial arms are of two types: rigid vane-type arms, and flexible filamentary-type arms, notably made of nylon or of metal. A corresponding method is also disclosed.
