Novel systems and methods for performing treatment (e.g., coloration) of keratinous fibers are disclosed. The methods and systems utilize one or more of a dispensing device which is configured to provide customized composition for treating keratinous fibers (e.g., a coloring composition), optionally formed from tablets; an optical reader, for obtaining sufficient characteristics of the keratinous fibers to make a realistic prediction of the outcome of a treatment (e.g., coloring treatment); a computational units for predicting an outcome of a treatment, optionally being interfaced with the dispensing device and for selecting a customized treatment; and tablet formulations which are useful in preparing customized composition for treating keratinous fibers. Further disclosed are rapidly disintegrating tablets for use in the preparation of compositions for treating keratinous fibers.

The invention provides a mixing container comprising: a liquid holding vessel having first and second chambers each for holding a different liquid; a mixing unit having a first valve and a second adjustable valve, the second adjustable valve having an opening that can be partially closed to permit a pre-determined portion of liquid from each chamber to be dispensed when pouring from the mixing container; and the second valve including a series of teeth around the periphery thereof for engaging an adjustment wheel in the mixing unit to open or close the opening in the second adjustable valve.

A system and process for mixing and distributing building materials. This system and process can also include a way or a means for calibrating the mixing of these materials. This system and process can also include a system for tracking the materials that flow through the system, and for controlling the type of material used in the system.

Methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

A feeding and blending apparatus for a system for continuous processing of powder products comprises at least two system inlets for powder products; and at least two feeding and dosing devices arranged in a row. Each of the at least two feeding and dosing devices comprises, an inlet being connected with a system inlet, at least one feeder, at least one actuator configured to operate the at least one feeder, and an outlet being connected with an inlet of the powder blending device. A separation wall is configured to separate a process area from a technical. Process components of the at least two feeding and dosing devices are positioned in the process area and technical components of the feeding and dosing devices are positioned in the technical area. Connections between the at least one actuator and the at least one feeder pass through the separation wall.

The present invention relates to an apparatus for mixing an additive with a gas flow, in particular for an exhaust gas system of a vehicle having an internal combustion engine, that comprises a mixing chamber which can be flowed through by at least a portion of the gas flow, said mixing chamber having at least one inlet opening through which a main inlet flow of the gas flow flows into the mixing chamber on operation of the apparatus, having at least one metering opening and having at least one outlet opening. The apparatus further comprises a metering device by means of which an additive flow of the additive can be introduced into the mixing chamber through the metering opening, wherein the inlet opening and the metering opening are arranged and formed such that the main inlet flow and the additive flow in substantially opposite directions into the mixing chamber so that the main inlet flow and the additive flow impact one another.

The invention belongs to the field of personalized cosmetics which, in terms of their composition, are determined by the end user (personalized), and it relates to a method for producing said cosmetics, and to dosing containers for the production thereof, and also to the use of cosmetic mixtures in the dosing containers and the use of the dosing containers for carrying out the method.

A module includes a housing, a sealing feature, a locking feature, and an agitator. The housing has an opening separating inner and outer surfaces and a boss that extends through the housing such that part of the outer surface forms an inner bore of the boss having a terminus pointing toward the opening. The agitator has a base, a shaft, and a mixing element coupled to the base such that the base, in cooperation with the sealing feature, circumferentially seals the opening of the housing to form a cavity defined by the inner surface. The shaft passes through the inner bore. The locking feature when engaged permits independent or simultaneous translational and rotational movement of the shaft while an area between the terminus of the boss and the shaft remains mechanically sealed during the movement against liquid or powder encroachment into a clean area of the inner bore.

The steps of providing a cleaning device, a liquid proportioning device and a series of tanks filled with liquids. The cleaning device has a nozzle, a series of hoses and a pump. The liquid proportioning device includes a series of passageways, having three chambers and two valves, and a manifold for mixing the liquids to form a cleaning solution. The passageways include knobs to set the ratio of each liquid that the user desires to mix into a cleaning solution. Once the cleaning solution is mixed, it is fed through a pump to cleaning device for use. The proportioning device allows a user to easily, quickly and accurately mix liquids to form a cleaning solution.
