The present disclosure relates to the field of mixing and dispensing apparatuses. A mixing and dispensing apparatus of the present disclosure facilitates automatic mixing and dispensing of a semi-liquid form of a powder material when mixed with a fluid. The apparatus comprises a mechanism to hold and rotate a cartridge, an actuation device, and an injection unit. The cartridge consists of the powder material to be mixed with the fluid. The mechanism rotates the cartridge about a primary axis of rotation and a secondary axis of rotation to uniformly mix the powder material with the fluid. The actuation device performs a piercing stroke to pierce one end of cartridge, and a dispensing stroke to dispense the semi-liquid form of the powder material through other end of the cartridge. Further, the injection unit is disposed within the actuation device to inject a pre-determined quantity of fluid following piercing stroke.

A powered surgical tool that includes a housing with a head and a handle that extends from the head. An electric motor is disposed in the head. A trigger extends from the handle. There is a void space in the handle. A plate separates the motor from the handle. Internal to the handle void space there is a rotor sensor and a control circuit. The rotor sensor is able to monitor the magnetic fields emitted by the motor rotor and that pass through the plate. The control circuit receives signals from the rotor sensor representative of the rotational orientation of the rotor and is further able to monitor the actuation of the trigger. Based on the rotor orientation signals and the actuation of the trigger, the control circuit generates signals that result in the selective generation of power signals to the motor rotor.

Involved is the technical field of a stirring device, specifically a stirring device for treatment of photoresist settlement and a photoresist tank. The stirring device includes a sleeve shaft, an inner telescopic shaft, a stirring component, and a rotary rod, wherein, the rotary rod is mounted on an upper end of the sleeve shaft for driving the sleeve shaft to rotate; the stirring component is arranged on a lower end of the sleeve shaft and rotates with the sleeve shaft; and the inner telescopic shaft is arranged inside of the sleeve shaft and connected to the stirring component for controlling opening and closing of the stirring component. Stirring plates approach a bottom portion of the photoresist tank, at which moment manual control is adopted to control stirring of the stirring device upward from the bottom gradually, so as to achieve the objective of homogeneous component of the photoresist. The photoresist is stirred to be more homogeneous. A lot of manpower and material resources are saved. The stirring device enables high stirring speed and high safeness.

A fluid mixer device that automates the mixing of multiple fluids into a base liquid and the delivery of the mixed liquid according to user-specified parameters with automatic flush-out, full logging and reporting capabilities. The device is comprised of a plurality of modules, each of which is designed for a different environmental setting: (a) the control module, the module with which the user interfaces, is normally located in a dry area, away from both line voltage electricity and fluids; (b) the power module, which supplies power to all modules, is located near 110 V-230 V single phase line voltage, and thus contains all of the high-voltage gear and interfaces; and (c) the flow module, the bank of controlled liquid mixers, is located in the wet area and uses only low-voltage direct current in its operation.

A method and apparatus for carbonating a liquid in a pressurizable vessel, including first connecting a vessel with a carbon dioxide tank, wherein said vessel contains a liquid. A vessel can then be pressurized with carbon dioxide to a desired first pressure. A pump is activated to circulate the liquid through a hose out of the vessel to a fitting assembly and out of the fitting assembly back into the vessel. While the liquid is flowing through the fitting assembly carbon dioxide is introduced to the liquid at a second pressure level, wherein the second pressure is greater than said first pressure. After a pre-determined period of time the pump is deactivated and the carbon dioxide can cease to be introduced to the liquid flowing through the fitting assembly.

A method of operation of a machine control indicator located on a first machine includes the step of monitoring operational parameters of a second machine operationally associated with a first machine. Each of the operational parameters is associated with a common clock of the machine control indicator. The operational parameters are stored in a memory of the machine control indicator with a date and time stamp based on the common clock. The operational parameters are transmitted along with the date and time stamp to a user device separate from the first machine and the second machine. In one embodiment, the operational parameters comprise one or more of a weight value, a rotation value, a revolutions per minute value, a peak weight value, a gearbox temperature value, and a hydraulic pressure value.

The present disclosure relates to a food preparation appliance and to a method and a computer program product. The food preparation appliance comprises a food preparation pot, a rotatable tool for chopping food in the food preparation pot and a sensor, in particular for weight determination of a food in the food preparation pot. A control unit is provided and configured such that, when a food is comminuted by the tool, the control unit is able to determine, based on a sensor signal from the sensor, whether a predetermined chopping state of the food has been reached. The present disclosure further relates to a method and a computer program product. It is thus possible to obtain a particularly reproducible cooking result.

A method for controlling a treatment apparatus arrangement in a treatment plant, the treatment plant including a basin housing a liquid and solid matter. The operating condition in the basin is anoxic and/or anaerobic, and the treatment apparatus arrangement includes at least one mixer machine located in the basin and a variable speed drive operatively connected to the mixer machine. The variable speed drive operates the mixer machine alternately in a Normal Operation Mode, in which an operational speed of the mixer machine is at least the greater of a suspension speed and a process speed, and a Reduced Operation Mode, in which the operational speed of the mixer machine is below the suspension speed. Also described is a treatment apparatus arrangement and a treatment plant, respectively.
