The system for making suspensions includes a housing, with a platform mounted therein and a translating table slidably mounted on the platform for removably supporting a receptacle. A base fluid tank stores a base fluid, and a solid particle container stores solid particles. A rotating dispenser system is mounted within the housing, above the platform and the receptacle. The rotating dispenser includes a base fluid dispenser for dispensing a controlled mass of the base fluid into the receptacle, and a solid particle dispenser for dispensing a controlled mass of the solid particles into the receptacle. The base fluid dispenser is in communication with the base fluid tank, and the solid particle dispenser is in communication with the solid particle container. A mixer selectively and controllably mixes the controlled mass of the base fluid and the controlled mass of the solid particles in the receptacle to form the suspension.

A mixing hub for use in semiconductor processing tools is provided. The hub may include a plurality of ports arranged about an axis, a mixing chamber, and a plurality of flow paths. Each of the flow paths may fluidically connect a corresponding one of the ports to the mixing chamber and each flow path may include a first passage, a second passage, and a valve interface. Each valve interface may be configured to interface with a valve such that the valve, when installed in the valve interface, is able to regulate fluid flow between the first passage and the second passage. Each valve interface may be located between a first reference plane that is perpendicular to the axis and passes through the corresponding port and a second reference plane that is perpendicular to the axis and passes through the mixing chamber.

A system for scanning a client's hair color and dispensing hair coloring to change the clients hair color from an initial color to a target color is disclosed. The system comprises an input for reading the measured color from the scanning device, a processor configured to compare the measured color to a desired target hair color and develop a coloring protocol for changing the clients current hair color to the desired target color, and a dispenser for dispensing one or more formulations that follow the protocol.

The invention relates to a method of operating a metering device (1) for metered dispensing of pumpable media, in particular of color pigment preparations, the metering device (1) comprising a dispensing means (2), which is in fluid connection with a plurality of canisters (3), wherein said metering device (1) comprises a controller (8) by means of which at defined times a defined dispensing volume of the medium is drawn from at least one of said canisters (3) and conveyed to said dispensing means (2) by means of a conveyor (10), wherein, in particular, by means of said controller (8) also an actual fill level is determined and/or calculated depending on a dispensing volume drawn from the respective canister (3). According to the invention, at least one calibration sensor (30), in particular a capacitive sensor, is arranged on said canister (3), preferably on an outer wall of said canister (3), in such a way that it is responsive in the event that the medium in said canister reaches at least a defined known calibration fill level, and transmits a corresponding sensor signal to said controller (8), based on which the controller (8) recognizes the calibration fill level as effective actual fill level and/or takes it over as a new current actual fill level. Further, a metering device and a canister are provided (FIG. 3).

A system forms a cosmetic composition. The system includes a dispensing arrangement in selective fluid communication with a plurality of dispensing dosing receptacles mounted on a movable carousel. The dispensing arrangement is configured to selectively dispense a plurality of the booster compositions together with a base composition corresponding to a formulation corresponding to a compatibility profile and consumer skin conditions to form a stable composition having efficacious concentrations of active ingredients into a receiving receptacle.
