A dilution apparatus includes a container having an adjustable float-operated make-up valve on the top of the container wherein the make-up valve has an inlet end connected to a water supply tube and an outlet end connected to a fill tube disposed inside the container. The make-up valve is connected to a float disposed in a liquid inside the container. The water supply tube is operatively connected by tubing to a reservoir that contains a concentrate. The water flow through the water supply tube siphons the concentrate through the tube, into the water stream and through the make-up valve to form a first dilution inside the container. A proportioner having a first inlet opening connected to a water supply and a second inlet opening connected to a tube on one end and the other end is connected to the bottom of the container. The water flow through the proportioner siphons the first dilution from the container through the tube and into the proportioner, thereby mixing the first dilution with the water from the water supply to form a final product having a predetermined dilution ratio.

A method and a device for carbonating a liquid medium, for example a beverage, by introducing CO2 under pressure into the liquid medium via at least one nozzle device (5, 5a, 5b, 21) which is arranged in a housing (3, 3a-c) through which the liquid medium flows.

A system includes a first pump feeding a first component into a mixer, and a second pump feeding a second component into the mixer. The movement of the piston of each pump can be reversed from a direction of suction and of expulsion of the volume of the pump to a direction of expulsion of the component and vice versa. A movement detector is associated with each pump and is connected to a controller programmed to trigger the reversal of a pump after having determined that the volume remaining in the pump is insufficient to ensure the predetermined metering ratio. The controller is programmed to provide the continuous feeding of the first component into the mixer through the operation of the system, and the intermittent feeding of the second component into the mixer in order to carry out cycles of feeding doses of the second component into the mixer.

A device for applying a two-part adhesive to a substrate includes a carrier, a first pump, a second pump, at least one manifold and at least one applicator. The first pump and the second pump are mounted on the carrier and each pump has an inlet and an outlet. The first pump pumps a first part of the two-part adhesive from its inlet to its outlet, and the second pump pumps a second part of the two-part adhesive from its inlet to its outlet. The at least one applicator is configured to mix the first part with the second part to form the two-part adhesive that is discharged from the outlet of the at least one applicator onto the substrate.
摘要:
A method for producing a multicomponent compound involves pressing components out of cartridges by means of pistons. The method has particular applicability in connection with dental applications. The method prevents pressing the components initially under high pressures. At the beginning of the pressing-out process, a pressure lower than the characteristic pressing-out pressure of the components from the cartridges is employed. Feed speeds are adjusted to constant value as a function of the pressing-out behavior of the components which are compared with stored or calculated values for a known material.
摘要:
In the production of diluted solutions in different concentrations, in each case an amount of a concentrate and an amount of a diluent are mixed. The ratio of the two amounts is never changed. The different concentrations of the diluted solutions result from concentrates of different concentrations that are used.
摘要:
An apparatus for supplying water containing dissolved gas comprising a flowmeter for measuring a flowrate of pure or ultra-pure water and a mechanism for controlling a flowrate, a means for adjusting an amount of water which adjusts an amount of the pure or ultra-pure water supplied to the apparatus for dissolving a gas, a tank which receives the water containing dissolved gas in an excessive amount which is not used at a point of use, a piping system through which the water containing dissolved gas glows from the tank towards the point of use and the water containing dissolved gas in an excessive amount returns to the tank, a piping system for supplying the water containing dissolved gas to the tank, and a controlling means for adjusting an amount of water based on a water level in the tank.
摘要:
A method, for obtaining a mix of a plurality of matters in a fluid state comprises providing for a first matter of the plurality of matters a first flow of matter. For each matter of the plurality of matters distinct from the first matter, a flow of matter is provided at a determined flow rate. The method further comprises gathering each flow of matter at an inlet of a mixer, the mixer continuously producing at an outlet a substantially homogeneous flow of matter corresponding to the mix.

Said device comprises a substantially tubular mixing chamber (1), a first inlet orifice for a stream (4) of the first gas at one end (2) of said chamber, a second inlet orifice (6) for a stream of the second gas, located downstream of said first orifice in the direction of flow of the stream of the first gas, means (10) for homogeneously mixing said streams of the first and second gases, said means being located downstream of said second inlet orifice, an outlet orifice (3) for the mixture, located downstream of said mixing means (10), at the other end of said chamber, and an orifice (11) for sampling said mixture of the first and second gases, said orifice being located between said mixing means (10) and said outlet means (3) for the mixture, said device furthermore including means (5, 8, 9) for sending the stream of the first gas into said chamber with a controlled flow rate and for sending the stream of the second gas into said chamber with a controlled flow rate.
摘要:
A method for mixing fluids in which a continuously variable flow rate stream of an injection fluid is introduced into a substantially constant flow rate stream of a primary fluid in a direction substantially transverse with respect to the direction of flow of the substantially constant flow rate stream of the primary fluid.
