Embodiments of the present invention include systems for storing large quantities of chemicals at a remote site. A controlled blending system balances the inflow of dry material and liquids into the blender based on a predetermined solid/fluid ratio. The blending system further balances the inflow and outflow of material from the blender.

A medical gas-liquid supply system including an electrolytic gas generator, a pure water supply device, a control unit, a first gas storing unit, a second gas storing unit and a gas output unit is provided. The control unit is electrically connected to the electrolytic gas generator for controlling the voltage value of the electrolytic gas generator and the type of gases generated by the electrolytic gas generator. The first and second gas storing units are communicated to the electrolytic gas generator for storing the first and second gases generated by the electrolytic gas generator respectively. The gas output unit is communicated to the first and second gas storing units and has first, second and third output ends for outputting the first gas, a mixed gas and the second gas respectively, in which the mixed gas includes the first and second gases.

Process and apparatus for producing helium, neon, or argon product gas using an adsorption separation unit having minimal dead end volumes. A second separation unit receives a stream enriched in helium, neon, or argon, and a stream is recycled from the second separation unit back to the adsorption separation unit in a controlled manner to maintain the concentration of the helium, neon, or argon in the feed to the separation unit within a targeted range.

The present disclosure provides improved systems and methods for the blending of active agents into process fluids.

Disclosed is an apparatus for preparing and dispensing a lubricant and coolant liquid product including a body with a base that defines a support surface for at least one container of an additive product and having a collection tank above which the container can be positioned, a storage reservoir of water suppliable from a water source, a mixing unit in communication with the reservoir and with the at least one container of the additive product, to mix the water and the additive product in a predetermined concentration, first pumping means adapted to pump the water from the reservoir toward the mixing unit, a control unit to control at least the first pumping means, and a dispensing circuit for dispensing the lubricant and coolant fluid obtained in the mixing unit. The body further includes a containing structure that encloses one, several or all the aforesaid components.

Systems and methods for blending fluids are provided. A blended fluid may be obtained by mixing a first fluid from a first fluid source with a second fluid from a second fluid source. The blended fluid may be pumped by a pump arranged downstream of a point at which the first and second fluids are mixed, wherein no other pumps are upstream of the pump. First and second flow control valves that control the flow rate of the first and second fluids, respectively, are adjusted so as to reach a target flow rate of the blended fluid, the blended fluid having a target blend of the first fluid and the second fluid.

A full-electric drive cementing control system is disclosed. The system includes: a water supply system for supplying clear water; an ash supply system for supplying dry ash; a slurry mixing system for performing a slurry mixing operation to form slurry; a plunger pump for pumping the slurry to a cementing operation object; and a control assembly for controlling, in response to a received cementing operation instruction, connection of a pipeline between an outlet of the water supply system and an inlet of the slurry mixing system and a pipeline between an outlet of the ash supply system and the inlet of the slurry mixing system, controlling, according to a preset slurry mixing parameter, the slurry mixing system to mix the clear water and the dry ash to form the slurry required for a cementing operation, and controlling, according to a preset perfusion parameter, a driving motor to drive the plunger pump to work, the cementing operation instruction carrying the preset slurry mixing parameter and the preset perfusion parameter.

An accessory for a kitchen appliance, particularly in the form of a measuring cup, for being attached to a cooking vessel, as well as to a correspondingly equipped kitchen appliance, wherein a sensor arrangement is arranged in the accessory and is capable of determining operating states, which are transmitted wirelessly to the kitchen appliance.

Methods for in situ mixing of two or more different liquid compositions by employing a dynamic flow profile characterized by a ramping-up section and/or a ramping-down section.

A nitrous oxide gas mixer includes at least one mixing chamber having at least one nitrous oxide gas connection and at least one oxygen gas connection for introduction of oxygen gas and nitrous oxide gas and at least one flow rate controller, by which a volume flow of the two gases can be respectively adjusted separately and/or together.

At least one O.sub.2 emergency button is mounted to the mixing chamber for emergency flooding the mixing chamber with oxygen gas and/or with ambient air.
