A gas mixing device for linearizing or calibrating a gas analyzer. The gas mixing device includes a first gas inlet line for a first gas, a second gas inlet line for a second gas, a mixing channel having inlet openings which are arranged one behind the other in a flow direction, the inlet openings comprising a first upstream inlet opening and a second downstream inlet opening, and at least two valves which each comprise at least one inlet and one outlet. The at least two valves release or block a fluidic connection between at least one of the first gas inlet line and the second gas inlet line, and the mixing channel via the inlet openings. A flow cross section of the mixing channel is smaller at the first upstream inlet opening than at the second downstream inlet opening.

An apparatus for gas mixing for a laser and/or air cutting machine. The apparatus includes a housing including a first inlet for nitrogen, a second inlet for oxygen, and an outlet for a gas mixture of the nitrogen and oxygen. A mixing unit including a mixer manifold between and connected to the gas outlet and each of the first and second inlets, the mixer manifold including a plurality of blending valves. A digital controller adjusts the plurality of blending valves, to achieve an oxygen percent in the gas mixture from about 0.5% to about 22%.

The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

Methods and systems of admixing hydrocarbon liquids from two or more sets of tanks into a single pipeline to provide in-line mixing thereof. In an embodiment of the in-line mixing system, hydrocarbon liquids stored in at least one tank of each of two or more sets of tanks positioned at a tank farm are blended into a blend flow pipe via in-line mixing and the blended mixture is pumped through a single pipeline. In one or more embodiments, the in-line mixing system employs a separate spillback or recirculation loop that is fluidly connected to each set of the two or more sets of tanks to control the flow of the hydrocarbon fluid/liquid from each set of tanks to the blend flow pipe. Associated methods of operating one or more embodiments of the system include regulation of spillback or recirculation loop flow rate and/or pressure to drive the actual blend ratio towards a desired blend ratio.

Apparatus and methods for variable-control fragrance dispensing. The disclosed device brings customization to the fragrance industry. Interchanging sub-containers and selecting the amounts of each sub-container allows a user to customize their scents. A mixing chamber contained to receive and mix a variable amount of each liquid from a plurality of sub-containers is described. The mixed liquid is sprayable out a spray head of the device. Selector knobs may be used to control valves which control the variable amount of each liquid dispensed.

Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline.
