The present invention relates to a nozzle for an air trapping device configured to remove air from a fluid, the nozzle comprising a body having an input opening configured to receive the fluid and an output opening configured to distribute the fluid along an edge of the output opening, wherein the edge comprises a control element configured to reduce surface tension of the fluid. The present invention further relates to an air trapping device 200 configured to remove air from a fluid and comprising the nozzle.

A lubricating oil tank includes: a tank casing having an introduction part into which lubricating oil is introduced and a discharge part through which the lubricating oil is discharged; a plurality of receiving parts which are disposed between the introduction part and the discharge part in the tank casing and which is configured to receive the lubricating oil introduced from the introduction part: and a lubricating oil delivery part which is configured to deliver the lubricating oil from one of the plurality of receiving parts to another one of the plurality of receiving parts between the plurality of receiving parts.

In one embodiment, the disclosed apparatus is an in-situ, closed-loop bubble and foam detection and reduction system that includes a liquid-level sensor to determine a volume of a liquid in a fluid reservoir, a mass-detection device to determine a mass of the fluid reservoir and any liquid contained within the fluid reservoir, a processor electrically coupled to the liquid-level sensor and the mass-detection device to determine an actual volume of the liquid within the fluid reservoir, and a showerhead coupled to the processor and positioned above the fluid reservoir. The showerhead is activated by the processor when a volume of the liquid determined by the liquid-level sensor exceeds the actual volume of the liquid by a predetermined amount. Other apparatuses and methods are disclosed.

In some examples a printing system includes purging manifolds. The printing system includes a fluid ejection device to dispense a fluid and a first reservoir to house a fluid. The system further includes a purging manifold to fluidically couple to the fluid ejection device, and the purging manifold to fluidically couple to the first reservoir. The purging manifold includes a second reservoir. The purging manifold further includes a supply port; a fluid inlet port; and a purging outlet port. The purging outlet port is disposed above the supply port to convey fluid to the first reservoir. The printing system also includes a fluid interface connector to fluidically connect to the supply port and fluidically connect to the fluid ejection device.

A deaerator includes a vessel having a chamber defined by an outer wall; and a tray module detachably connected to the vessel, the tray module having a plurality of deaerator trays which are connected to one another in a spaced relationship to form a stack which is suspended within the chamber.

A stirrer is provided that can more efficiently achieve shearing applied, by an action of an intermittent jet flow, to a fluid to be processed. The stirrer concentrically includes a rotor including a blade, a partition wall, and a screen, wherein: the screen includes a plurality of slits in a circumferential direction thereof and screen members located between the adjacent slit; by rotating at least the rotor of the two components, the fluid to be processed is discharged from the inside to the outside of the screen as the intermittent jet flow through the slit of the screen; the screen has a cylindrical shape having a circular cross section; an opening of the slit provided on the inner wall surface of the screen is used as an inflow opening; openings of the plurality of slits provided on the outer wall surface of the screen are used as outflow openings; and the width of the outflow openings in the circumferential direction is set to be smaller than the width of the inflow opening in the circumferential direction.

Provided is an ultra-fine bubble-containing liquid manufacturing apparatus that can suppress viable cell contamination inside a UFB generating unit. To this end, it is provided with an ultra-fine bubble generating unit that generates an ultra-fine bubble by making film boiling by a heating unit in a liquid in which a gas is dissolved, and a radiating unit that is capable of irradiating a wetted portion of the ultra-fine bubble generating unit with ultraviolet rays.

This invention relates to a liquid degassing means, and method of operation. The means comprises a tank, the tank having one or more baffle(s) within the body of the tank, with at least one baffle defining a first and second region. The first region houses relatively turbulent conditions compared to the second region. There is a both a gas transfer gap and a liquid transfer gap, allowing the transmission of fluid from the first to second regions. An inlet introduced the mixture to be degassed to an antechamber, with the fluid travelling onwards to the first region, and then through the gas and liquid transfer gaps to the second region. A first outlet allows for the degassed liquid to leave the tank, and a second outlet allows for the purged gas mixture to also leave the tank. Sensors and complementary control units allow for better operation of the unit.

A trihalomethane (THM) and volatile organic compound (VOC) removal system includes: a storage vessel; a fluid inlet on the storage vessel where fluid enters said storage vessel; a fluid outlet on the storage vessel where fluid exits said storage vessel; and a fluid fitting on said storage vessel. Fluid leaves the storage vessel via an inlet conduit attached to the fluid fitting and flows through a pump and passes through a venturi aspirator, and returns to the storage vessel through an outlet conduit attached to the storage vessel.
