The invention refers to a combined storage, dosing and mixing device (1), which comprises a first compartment (2) and a second compartment (3) and a dosing section (4) between the first compartment (2) and the second compartment (3). The dosing section (4) comprises a translatory movable slider (10, 10a) adjacent to the first compartment (2), a pivotally movable flap (11) adjacent to the second compartment (3) and a dosing space (C) between the slider (10, 10a) and the flap (11).

Provided is a container, which comprises a container body and a cover and further comprises a variable-pressure component, a metering channel, a liquid extraction channel and an outflow channel. The head of the metering channel is in communication with the variable-pressure component, and the tail thereof is in communication with the outflow channel and the liquid extraction channel. A valve, which is opened when the variable-pressure component is pressurized and is closed when the variable-pressure component is depressurized, is provided between the metering channel and the outflow channel. A valve, which is opened when the variable-pressure component is depressurized and is closed when the variable-pressure component is pressurized, is provided between the metering channel and the liquid extraction channel or within the liquid extraction channel. The metering channel, the liquid extraction channel and the outflow channel are fixed to the cover.

Provided is a self-metering container, an initial positioning device thereof and an initial positioning method. The container comprises a container body, a variable pressure component, a metering channel and an outflow channel. When the variable pressure component is depressurized, contents in the container body enter the metering channel; and when the variable pressure component is pressurized, the contents in the metering channel flow outwards via the outflow channel. The container further comprises an initial positioning device. The initial positioning device comprises a backflow cavity, a backflow channel and a component capable of closing the backflow channel. The backflow cavity is in communication with the variable pressure component and the initial end of the metering channel. The initial end of the metering channel is higher than the bottom of the backflow cavity. The backflow channel is in communication with the bottom of the backflow cavity and the container body.

The present disclosure is directed to a device having a nozzle for dispensing a liquid target material; one or more intermediary chamber(s), each intermediary chamber positioned to receive target material and formed with an exit aperture to output target material for downstream irradiation in a laser produced plasma (LPP) chamber. In some disclosed embodiments, control systems are included for controlling one or more of gas temperature, gas pressure and gas composition in one, some or all of a device's intermediary chamber(s). In one embodiment, an intermediary chamber having an adjustable length is disclosed.

Provided are a flowrate measuring type viscous liquid dispenser and dispensing method, in which a viscous liquid is dispensed by measuring a flowrate of the viscous liquid in real time so as to accurately control the flowrate of the viscous liquid.

A dosing method for carrying out at least one dosing operation, including the steps: providing a switching signal to or from a valve control, providing a coil current from the valve control to a magnetic drive in dependence on the switching signal, in which the magnetic drive is configured to move a valve member of a solenoid valve between a normal position and a functional position, determining a first start of movement of the valve member from the normal position to the functional position, determining an operating duration between the provision of the coil current and the first start of movement, determining a providing duration for the switching signal. The provision of the coil current is carried out over a coil current duration which corresponds to a sum of the providing duration and the operating duration.

The invention relates to a metering system (1) for metering a metered medium comprising a frame housing unit (2) and a lever mounting unit (3) which his supported on the frame housing unit (2) comprising a lever mount (4). The invention further comprises a, preferably asymmetrical lever (30) which is supported rotatably by means of the lever mount (4) about a tilt axis (R) comprising a two-sided lever arm (31) extending substantially in a longitudinal direction (30L) of the lever (30), wherein one lever arm side (35), preferably the longer lever arm side (35), has a first actuator engagement point (36) close to the tilt axis and is in contact remotely from the tilt axis at an end portion (33) with an ejection element (13), preferably a ram (13), and wherein the other lever arm side (32), preferably the shorter lever arm side (32), has a second actuator engagement point (37) close to the tilt axis. The invention further comprises two actuators (50a, 50b), which, during operation, exert a tilting moment in opposite directions on the lever (30) at the first and second actuator engagement point (36, 37), wherein the actuators (50a, 50b) are placed obliquely to one another. Together, the lever mounting unit (3), the lever (30), and the two actuators (50a, 50b) thereby form a movement mechanism (4, 30, 50a, 50b), which is braced on the frame housing unit (2) by means of at least one spring element (21), preferably a disc spring set (21), wherein the spring element (21) is preferably arranged so that it braces the lever mounting unit (3) against the frame housing unit (2) via the lever (30) as well as via the two actuators (50a, 50b).
