Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

The present invention discloses a handheld device 200 and a method for creating customised cosmetic colours instantly. The handheld device 200 comprises a holder body 202 with two or more slots to house two or more dispensers that dispense two or more base colour liquid lipsticks. The handheld device 200 further comprises a container 212. In order to create customised liquid lipsticks, a user follows a colour recipe chart 600 and dispenses the two or more base colours in the two or more dispensers in predetermined ratios to create a custom colour in the container 212. While the present description focuses on creating liquid lipsticks, it will be apparent to those with ordinary skill in the art that the handheld device 200 and the method can be used to create any other colour cosmetics or artists colours.

A delivery system of a colored product having a target color including an application device of the colored product, at least two reservoirs each containing a respective base product, a calculation module configured to receive the information concerning the target color and to determine a composition of the colored product from the base products contained in the reservoirs, at least one metering device in fluid communication with the reservoirs, configured to deposit on the application device a dose of each of the base products corresponding to the determined composition, a mixing device configured to mix the doses of base products deposited on the application device. Also, a method for delivering a colored product having a target color via the delivery system. Finally, the use of the system for applications requiring the delivery of a colored product having a target color.

An apparatus for dye dispensing is disclosed herein. The apparatus includes a controller and a tray. The tray communicates with the controller and is configured with at least one opening. At least one canister is configured with an identifier and a dye. The dye is associated with the identifier. A reader communicates with the controller. A dispenser comprises an actuator communicating with the controller and a lever arm. The lever arm is coupled to the actuator and configured with a projection. The reader, based on the identifier, identifies a selected dye in a selected canister associated with a dye formulation. When the selected canister is aligned with a dispensing area, the dispenser applies a downward force on the selected canister and dispenses the selected dye.

This system (1) for mixing a chemical product with water comprises a water inlet port (3) designed to be connected to a pipe for supplying water under pressure, a chemical product inlet port (5) designed to be connected to a chemical product reservoir (100), and a mixture outlet port (7). It comprises a main chamber (11) in which is movable a piston (13) delimiting an upstream part (15) of the main chamber (11) that is fluidly connected to the water inlet port (3) and a downstream part (19) of the main chamber (11) that is connected to the chemical product inlet port (5), wherein the piston (13) is provided with a rod (130) extending in the downstream part (19) of the main chamber (11). The water inlet port (3) is also connected to the mixture outlet port (7), wherein the downstream part (19) of the main chamber (11) is also connected to the mixture outlet port (7). A water flow rate regulating device (60) is interposed between the upstream part (15) of the main chamber (11) and the water inlet port (3). The piston (13) is movable in the main chamber (11) under the action of the water entering the upstream part (15) of the main chamber (11) and the pressure difference created by the rod (130) of the piston (13) in the downstream part (19) of the main chamber (11), so that the chemical product contained in the downstream part (19) of the main chamber (11) is directed towards the mixture outlet port (7).

Apparatus (100, 200, 300, 400, 500, 600) for customized production of a flavoring agent, the apparatus too, (200, 300, 400, 500, 600) comprising: a retainer (110, 210, 310, 610) for retaining at least two containers (10), each container (10) comprising a respective flavoring agent; a collecting and dispensing unit, e.g. a manipulator (120, 220, 320), for collecting and dispensing flavoring agents; a mixer (130, 230, 330) for mixing flavoring agents for obtaining a new flavoring agent; a control-unit (140) for controlling at least the collecting and dispensing unit (120, 220, 320) and the mixer (130, 230, 330), and a communication unit for communicating with a remote server (41) and/or remote device 20, wherein the control-unit (140) is configured such that the collecting and dispensing unit (120, 220, 320) collects and dispenses a first defined amount of flavoring agent from a first container (10) to the mixer (130, 230, 330), the collecting and dispensing unit (120, 220, 320) collects and dispenses a second defined amount of flavoring agent from a second container (10) to the mixer (130, 230, 330), and the mixer (130, 230, 330) mixes the first and second defined amount of flavoring agents inside of the mixer (130, 230, 330) for producing the new flavoring agent.
