Multi-conduit connector apparatuses for use in negative pressure wound therapy (NPWT) apparatuses to wound dressing, and methods for installing multi-conduit connector apparatuses in NPWT apparatuses.

The present patent application relates to a dispense interface comprising a channel profile with at least two inlet channels and at least one outlet channel, wherein each of the at least two inlet channels is configured for fluid communication with a respective reservoir of at least two reservoirs, at least one top layer and one bottom layer, an intermediate layer structure arranged between the at least one top layer and one bottom layer, wherein intermediate layer structure is tightly laminated with the top layer and the bottom layer and wherein the intermediate layer structure comprises at least one intermediate layer comprising at least one recess for forming at least one part of the channel profile.

Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet and provide a combined flow of pressurized gas and urea to an outlet, flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position, the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.

Apparatus and methods for supplying a gas to a processing chamber are described. The apparatus comprises an inlet line, an outlet line and a fill line in fluid communication an ampoule. The apparatus described, and methods of use, allow a precursor ampoule to be refilled during processing without removing or replacing the ampoule and interrupting the process.

A water delivery system is disclosed. The water delivery system may have an electronic user interface. The electronic user interface may be a portable device. The electronic user interface may include inputs to select water temperature, water flow rates, water flow patterns, and/or task based presets. A mixing valve for use with either manual faucets or electronic faucets is disclosed.

A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.

A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

A water delivery system is disclosed. The water delivery system may have an electronic user interface. The electronic user interface may be a portable device. The electronic user interface may include inputs to select water temperature, water flow rates, water flow patterns, and/or task based presets. A mixing valve for use with either manual faucets or electronic faucets is disclosed.

Methods and apparatuses for additively manufactured tubular passages, additively manufactured manifolds, and additively manufactured heaters are provided.

A method for operating a fluid additive control system to inject a fluid additive into a fluid dispensation system is provided. The method includes receiving a first control signal indicating that a fluid dispensation device within the fluid dispensation system is active, and determining a fluid additive quantity based upon the identity of the fluid dispensation device. The method also includes activating a fluid additive injection system, where the fluid additive dispensation system injects the fluid additive into the fluid dispensation system in response to the activation. The method further includes receiving a second control signal from the fluid additive injection system when the fluid additive quantity for the zone has been injected into the fluid dispensation system, and deactivating the fluid additive dispensation system in response to the second control signal.
