  • Patent number: 8518259
    Abstract: An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.

  • Patent number: 8449767
    Abstract: An oil reservoir having an oil inlet fitting and at least one oil outlet fitting for connecting to a hydraulic system. The reservoir comprising a housing having a lower housing part and a reservoir cover which is connected to the lower housing part and includes an integrated oil filter. An oil filler neck, which can be closed by a cap, is configured on the housing cover. The reservoir housing is equipped with at least one guide element which is attached to at least one inside wall of the reservoir housing and forms a circular guidance track for the oil. This guidance track forces the oil flow in a circular manner, after entering the reservoir and passing through the oil filter but before exiting the oil reservoir, such that any air which may be present is separated from the oil and can exit the oil reservoir via an air outlet.

  • Publication number: 20130068702
    Abstract: A filter element is provided with a snorkel that facilitates bleeding of air along the outside periphery of a tubular filter media pack to a bleed chamber contained within the filter element. This may be employed in fuel filtration applications during installation and removal of filter elements whereby air can be temporarily trapped in a housing containing the filter element. The snorkel thus vents the air along the outside of the filter element and then into a bleed chamber where it can be communicated to a standpipe having an isolated bleed passage.

  • Publication number: 20130068679
    Abstract: A stormwater treatment unit comprising a containment vault having an inlet and an outlet separates debris from a flow of stormwater through the unit. The water flow is controlled by a wall which directs flow from the inlet to the outlet through a reservoir of fluid in the unit. Debris separation by density occurs whereby lighter elements such as oil float on top of the fluid and heavier elements such as sediment collect at the bottom of the unit or in collectors in the reservoir. A wire mesh, deflector, and/or ripple boards placed beneath the inlet further increase efficiency of the separation, and a vent pipe is placed above the outlet to release pressure built up in the outlet during operation. A stormwater treatment system and method of retrofitting an existing stormwater trunk line locates the stormwater treatment unit in an off-line position from an existing drainage trunk line.
