In one example, a build material supply system for additive manufacturing includes a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material.

A control system for mixing materials for livestock feed including a container that receives the materials, agitators that mix the materials in the container, a driveline that drives the agitators at an output speed with an output torque, a power source that provides an input speed at an input torque, a continuously variable transmission that connects the driveline and the power source and having a hydrostatic loop to provide a speed ratio between the input speed and the output speed, a plurality of sensors positioned between the power source and the agitators that provides mixing signals commensurate to mixing parameters, and an electronic control unit configured to receive the mixing signals, extract mixing parameter values from the mixing signals, and actuate the continuously variable transmission and adjust the speed ratio based on the mixing parameter values to enhance efficiency of the mixing of the materials.

Described are systems and methods of mixing a liquid in a container, while liquid is being added or removed from the container, and with control of the speed of a mixing device that mixes the liquid to prevent an undesired mixing effect such as splashing, formation of a vortex, foaming, and vibration of a shaft of a mixing device used to mix the liquid.

A mixer apparatus for mixing a high-viscosity fluid has a mixer shaft with a plurality of blades affixed thereto, a hydraulic motor drivingly connected to the mixer shaft so as to rotate the mixer shaft, a hydraulic pump connected by a fluid circuit to the hydraulic motor so as to deliver hydraulic fluid under pressure to the hydraulic motor, an electric motor drivingly connected to the hydraulic pump, and a hydraulic fluid reservoir connected to the fluid circuit so as to supply hydraulic fluid to the hydraulic pump. The plurality of blades are pivotally mounted to the mixer shaft.

A galley insert beverage making system for producing chilled drinks comprising: a body configured to be inserted into a vehicle galley compartment. The body comprises: a cooling system; and a motor. The galley insert beverage making system also comprises a pitcher system. The pitcher system comprises: a pitcher; a blending element configured to be rotationally driven by the motor; and a stirring element configured to be rotationally driven by the motor. The body defines a cavity configured to receive the pitcher, and the system is configured such that the cooling system cools the pitcher.

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 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.

For expanding the scope of functions of an existing magnetic stirrer in a simple manner, a function adapter (3) is proposed which is equipped in order to convert a movement variable fed into the function adapter (3) by a magnetic stirrer (2) and output the same in a converted manner.

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.
