The present disclosure provides for a first embodiment, where, a first, lower shaft speed mixing of the component combination takes place in a thermokinetic mixer, where monitoring of the batch by temperature rate increase determination results in a determination that a substantial portion of desired thermokinetic mixing has occurred, whereafter a different shaft speed is used to complete the desired thermokinetic mixing of the component combination.

One example of correlating energy to mix well cement slurry under laboratory conditions to field conditions can be implemented as a method to determine energy to mix cement slurry. Electrical power supplied to an electric mixer in mixing a specified well cement slurry is measured. An energy to mix the specified well cement slurry is determined from the measuring. The determined energy to mix the specified well cement slurry and specifications of field equipment for use in mixing the specified well cement slurry at a well site are compared. The field equipment is a different configuration than the electric mixer. Based on the comparing, it is determined whether the well cement slurry needs redesigning according to capabilities of the field equipment.

An operable measuring attachment for a mixing appliance includes a mixing bowl defining a mixing interior, a housing having a protrusion attachable to the appliance and a plurality of containers each having an interior volume. Each container is alternatively operable between a measuring position engaged to a top of the housing, and a disengaged position distal from the housing. The operable measuring attachment also includes a magnetic coupler having a first magnetic member disposed proximate the base of each of the plurality of containers and a second magnetic member disposed proximate the top of the housing. The selective magnetic engagement of the first magnetic member of any one of the plurality of containers and the second magnetic members further defines the measuring position. A scale is disposed within the housing that is in communication with the interior volume of the container in the measuring position.

A tintometric machine includes an external frame made from rigid material, which defines an internal area. The internal area houses at least one dispenser system, which can dispense at least one fluid, such as paint or dye, into a vessel or container. The dispenser system of the tintometric machine, includes one or more dispenser mechanisms and a plurality of canisters or containers. Each of the dispenser mechanisms includes at least one pump and at least one valve assembly, and the canisters or containers are connected to one or more dispenser mechanisms. The external frame of the machine has a shell-shaped structure that can be opened to divide the machine into at least two portions. Each portion contains a part of the dispenser system. By dividing the machine into portions, an inspection area is defined between the portions, which is accessible to an operator.

Assembly of a tintometric machine and a trolley includes an external frame and a dispenser system. The dispenser system dispenses a fluid into a vessel or container, when the vessel or container is positioned in a dispensing station. The trolley includes: a supporting top, whereon the container can be positioned; rotary elements allowing the trolley to move; a gripping element, through which the user can grip the trolley and move it. The dispensing station has a housing into which the trolley can be positioned. The assembly includes a plug-socket system, wherein a first part of the system is located on the trolley and a second part is located in the dispensing station. The parts of the system can be assembled together when the trolley is placed into the housing of the dispensing station, for the purpose of conducting an electric current. The trolley includes an actuating device that can move the supporting top.

Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).

The invention provides a method of operating a batch mixer for producing first and second numbers of mixtures from first and second numbers of batches of materials to be mixed in the batch mixer, the batch mixer comprising a mixing chamber, a mixing element disposed within the mixing chamber, the mixing element and the mixing chamber being configured for providing an identical flow of the materials to be mixed within the mixing chamber and around the mixing element regardless of in which of the first and second opposite directions the mixing element is rotated, and a motor assembly coupled to the mixing element for rotating the mixing element for mixing the first and second numbers of batches of materials to be mixed for producing the first and second numbers of mixtures. The method comprises the steps of energizing said motor assembly for rotating said mixing element in said first direction, for each one of the first number of batches of the materials to be mixed: loading the one of the first number of batches of materials to be mixed into the mixing chamber, mixing the one of the first number of batches of materials for producing one of the first number of mixtures, and removing the one of the first number of mixtures from the mixing chamber, energizing the motor assembly for rotating the mixing element in the second direction, and for each one of the second number of batches of the materials to be mixed loading the one of the second number of batches of materials to be mixed into the mixing chamber, mixing the one of the second number of batches of materials for producing one of the second number of mixtures, and removing the one of the second number of mixtures from the mixing chamber.

An apparatus for making a battery slurry is disclosed. The apparatus comprises a vacuum system providing a vacuum environment, a dry powder mixing device mixing a plurality of powdery materials uniformly to obtain a dry powder, a kneading device kneading the dry powder with the first part solvent to form a doughy mixture, and a high speed dispersing device dispersing the doughy mixture to the second part solvent to form the battery slurry.
