The invention relates to a test set (1) for a photometric measuring device, comprising a mixing container (2) which has a filling opening (3) and comprising a metering container (8) which can be sealingly inserted into the filling opening (3) of the mixing container (2) and which contains a liquid reagent (13) in a closed cavity (9). The cavity (9) has a closure plunger (11), which can be moved axially in the cavity (9), at a first end of the metering container (8), said closure plunger generating a specifiable filling pressure in the reagent (13), and the metering container (8) has a closure membrane (10) at a second metering container and which can be inserted into the mixing container (2). According to the invention, the closure membrane (10) is equipped with a predetermined breaking point (20) which breaks open when the filling pressure is exceeded in a defined manner as a result of an axial movement of the closure plunger (11), said predetermined breaking point (20) of the closure membrane (10) being formed as a linearly extending material taper of the closure membrane (10), wherein the taper is arranged eccentrically in the region of an opening (24) in the base (23) of the substantially cylindrical metering container (8).

A food preparation appliance has a base, a blade member rotatable in a direction of rotation, and a container with a closed bottom, an open top and a tubular sidewall together defining an interior space of the container. The top of the container is configured for releasable connection with the base, with the blade member disposed within the interior space of the container. The sidewall has a rib projecting inward of the interior space of the container and extending lengthwise along at least a portion of the sidewall from the top of the container toward the bottom of the container. The rib has, in the direction of rotation of the blade member, a peak defined as the shortest transverse dimension measured from the center of the container to the sidewall at a respective height along the portion of the sidewall having the rib, the rib being asymmetric in transverse cross-section.

A jar or other storage container with an integrated stirring device, where the contents of the jar or storage container can be stirred and mixed together without having to completely open the jar or storage container. The core components in one embodiment are a top portion that contains external threads, a lid portion which contains internal threads, a spindle with an etched self-reversing screw pattern, a hub, one or more stirring blades, and a nut. The stirring blades have one end attached at a hub that is free to rotate on the spindle, the other end is attached to a nut that can travel up and down the self-reversing screw pattern, and the spindle is fixed to the lid portion. The surface area of the stirring blade(s) can be changed to accommodate different thicknesses and viscosities of different fluids and semi-fluids placed in the storage container.

A mixing system includes a housing having a motor mount rotatably coupled thereto, the motor mount having a passage extending therethrough. A drive shaft is removably positioned within the passage of the motor mount. A cap includes a main body removably coupled to the motor mount and an actuator coupled to the main body so as to be pivotable between a first position and a second position with respect to the main body. The actuator producing a camming action when the actuator is pivoted such that when the actuator is in the first position, the actuator pushes the drive shaft against the motor mount so that the main body is locked to the motor mount and so that rotation of the motor mount causes rotation of the drive shaft and when the actuator is in the second position, the actuator is disengaged from the drive shaft and the cap is removable from the motor mount.

Analyzers are described that control sample agitation by detecting vibration acceleration and using feedback to control the agitation and also alert to the presence of abnormal agitation. An embodiment provides an analyzer comprising a liquid agitation unit; an agitated liquid analysis unit; and a unit that controls the agitation unit. The agitation unit includes a vibrator of a liquid container and a detector of vibration of the container and that outputs a signal to the control unit, which responds by regulating the vibrator.

The disclosure relates to an application device for multi-component substances, in particular multi-component adhesives or multi-component sealants, including: at least two cartridge receiving devices for receiving replaceable cartridges with substance components that are to be mixed; a discharging device for discharging the substance components from the cartridges; a mixing device for mixing the substance components, wherein the mixing device includes a rotary mixer which is driven via a drive shaft, the drive shaft having at least one flexible portion with a first end and a second end.

Provided are a water treatment apparatus and a water treatment method capable of performing a significant water quality evaluation of treated water before the filtration process, and capable of rapidly responding to a change in water quality of the treated water. A water treatment apparatus of the present invention includes a treated water filtering unit which filters treated water supplied from a treated water line to become filtered water, a filtered water mixing unit which is provided in a treated water extraction line diverging from the treated water line to reduce a turbidity concentration in the treated water of the treated water extraction line to become measured water, and a water quality measuring unit which is provided at a rear stage of the filtered water mixing unit in the treated water extraction line and measures water quality of the measured water to evaluate the water quality of the treated water.

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.

An apparatus is disclosed for mixing substances, such as paint. The apparatus includes an elongate member with a plurality of openings formed within it. A filament is threaded through the openings creating bights between openings. The bights and ends of the filament sweep through the substance when the elongate member is rotated, which works to mix the substance.

A batch gasification assembly comprises a pressure vessel having an open end and being configured to contain a beverage to be carbonated and a flexible seal that covers the open end of the pressure vessel. A closure mechanism for the pressure vessel comprises a retainer configured to receive and retain the open end of the pressure vessel, a top cap, and an over-center clamping mechanism that is configured to clamp the top cap onto the open end of the pressure vessel so that the flexible seal member is sandwiched between the top cap and the open end of the pressure vessel.
