A device for packaging and dispensing a chemical product is provided. The device may include a first portion connected to a second portion. Counterpoising locking features may secure the first portion and the second portion. A support member is disposed within the lower portion and adapted to support the product. The device may include a flexible enclosure contoured to and enclosing the rigid body and the product. The flexible enclosure may enclose a portion of the housing and the product, after which heat is applied to shrink the flexible enclosure. A handle may provide for ease of installation and/or removal of the device from a solid chemical dispensing system.

A substrate processing apparatus includes a chamber, a manifold including a tubular portion above the chamber, first and second introduction pipes provided on a side surface of the tubular portion, and a gas guide portion to guide, in a direction opposite the chamber, gases introduced from the first and second introduction pipes into the tubular portion, and then introduce the gases into the chamber. The gas guide portion does not contact a top of the manifold, and the manifold includes a space above the gas guide portion to allow the gases to flow from between the gas guide portion and the tubular portion into a space surrounded by the gas guide portion. The gas guide portion advantageously enables the gases to broadly diffuse and uniformly mix, increasing the quality of a film formed on a substrate inside the chamber.

Provided is a substance mixing apparatus including two or more flow paths in which orifices, from which a fluid that flows therethrough is externally discharged, are formed, oscillation devices that form droplets of the fluid discharged from each of the orifices by oscillating at least the orifice part of the flow paths at a predetermined oscillation frequency and discharge the droplets, and means for causing the droplets discharged from the orifices of the flow paths to collide with one another.

A fine bubble generation device in one aspect of the present disclosure is a device that generates fine bubbles in a liquid by causing the liquid to pass through a porous element having many pores. In the fine bubble generation device, a differential pressure is applied between first and second sides of the element, and, by the applied differential pressure, the liquid disposed on the first side of the element is passed through the element and is jetted toward the second side to thereby generate fine bubbles. In this fine bubble generation device, the flow speed of the liquid during passage through the element is 0.009769 [m/s] or higher. The fine bubbles can thereby be generated efficiently.

A closure device for firing an additive into a carbonated beverage bottle with a neck comprises a cap member and a housing. The cap member includes a pressurised tank containing the additive and a propellant and has a bottom aperture. The housing engages with the neck and includes a plug member which engages with the bottom aperture. The cap member can be lifted relative to the housing from a first armed or closed position in which the plug member closes the bottom aperture to a second firing position in which the plug member provides a communication path from the tank through a nozzle in the plug member.

A fluid dispersing device includes a tubular first wall portion with an axis extending in a first direction defined as a central axis, and a second wall portion separated downward from the first wall portion. The second wall portion includes at least one circular member and a disk-like member each having a flat surface for causing a fluid passing through an inner space of the first wall portion to collide therewith. The disk-like member is separated downward from the at least one circular member. The at least one circular member has an outer diameter equal to or smaller than an inner diameter of the first wall portion. The disk-like member has an outer diameter equal to or smaller than an outer diameter of the closest circular member.

A method and system for treating wastewater is disclosed. In one example the method comprises activating a mixing system that imparts a motive force on wastewater in a vessel, measuring at least one property of a first portion of the wastewater at a first time, measuring the at least one property of a second portion of the wastewater at a second time subsequent to the first time, calculating a difference between the at least one property measured at the first time and the at least one property measured at the second time, performing a determination of whether the difference is within a predetermined allowable range of differences, and responsive to a result of the determination, controlling a component of the mixing system.

A process and device to create access to low gravity solids (LGS) of about 2 to 20 microns for removal from a fluid material/LGS emulsion having the steps of: flowing the emulsion into high pressure tubing; separating the emulsion into at least two high pressure streams; forcing the emulsion through high pressure nozzles at a terminus of each of the at least two high pressure tubing streams at a speed in the range of about 10 ft/sec to 200 ft/sec or at a force in a range of about 10 to 100 PSI; and colliding the streams of emulsion exiting the high pressure nozzle within a pressure drop chamber, wherein the pressure drop is in a range of about 5% to 50% of the back pressure of the nozzles; wherein a cavitation effect is realized from a collision force of the high pressure streams within the pressure drop chamber.

A gas mixing system for semiconductor fabrication includes a mixing block. The mixing block defines a gas mixing chamber, a first gas channel fluidly coupled to the gas mixing chamber at a first exit location, and a second gas channel fluidly coupled to the gas mixing chamber at a second exit location, wherein the first exit location is diametrically opposite the second exit location relative to the gas mixing chamber and the second gas channel has a bend of 90 degrees or less between an entrance of the second gas channel and the second exit location.

The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.
