A hybrid Contact tray for a mass transfer column is provided. The tray has a deck for passage of liquid along a liquid flow path thereon. The deck also has a plurality of orifices for passage of ascending vapor through the tray deck. The contact tray includes a cross-current vapor-liquid mixing section having a first portion of the plurality of orifices and a co-current vapor-liquid mixing section having at least one co-current mixing device associated with a second portion of the plurality of orifices. The co-current mixing device includes a conduit having: a vapor inlet in fluid communication with one or more of the second portion of orifices; a froth inlet in fluid communication with the liquid flow path; a fluid outlet; and a packing material within a co-current flow path of vapor and liquid within the conduit disposed after the vapor and froth inlets and before the fluid outlet.

A swirler includes a swirler body and a plurality of axial swirl vanes extending radially outward from the swirler body. At least one of the swirler body or vanes includes a spring channel defined therethrough. A fuel injector for a gas turbine engine can include an inner air swirler and/or outer air swirler as described above.

A carbonation machine includes a carbonation head to sealingly couple to a bottle filled with liquid to be carbonated; a piping to introduce and compress carbon dioxide into a space within the bottle above a top surface of the liquid to a predetermined pressure level when the bottle is coupled to the carbonation head; a stirrer to stir the liquid to enhance absorption of carbon dioxide in the liquid when the bottle is coupled to the carbonation head; and a manually operated valve mechanism configured to be moved to any position between a closed position to an open position for user-controlled release of pressure within the space.

An aerator accessory has a handle having a main body and a plurality of connecting joints surrounding the main body, a top end and a bottom of each connecting joint respectively connected to a socket with different diameters. Each socket has an opening end and an inner sidewall, and one opening end of at least one of the sockets has a first fastening portion with a plurality of engaging teeth disposed evenly around the opening end. One inner sidewall of at least one of the sockets has a second fastening portion with two opposite parallel tangent planes. One inner sidewall of at least another socket has a third fastening portion comprising at least two fastening grooves on the inner sidewall.

A container system includes a collapsible bag having an interior surface at least partially bounding a chamber, the chamber being adapted to hold a fluid. A sparger is disposed within the chamber of the bag, the sparger bounding a compartment and having an inside edge that encircles an opening passing through the sparger. At least a portion of the sparger is gas permeable. A tubular member is coupled to the sparger and is in communication with the compartment. A shaft passes into the chamber of the bag and through the opening of the sparger. A mixing element is secured to the shaft and is disposed within the chamber of the bag.

A gas/fluid mass exchange apparatus is disclosed. The apparatus comprises a gas permeable membrane which is arranged to separate a first region for receiving a gas flow, from a second region for receiving a fluid flow. The apparatus further comprises support means which is arranged to maintain the shape and orientation of the membrane.

A container system includes a bag comprised of one or more sheets of flexible polymeric material, the bag having an interior surface at least partially bounding a chamber, the chamber being adapted to hold a fluid. A flexible sparging sheet is secured to the interior surface of the bag so that a compartment is formed between the interior surface of the bag and the sparging sheet, at least a portion of the sparging sheet allowing gas to pass therethrough. A tubular port or tube is secured to the bag so that a passage bounded by the tubular port or tube communicates with the compartment. A mixing element is disposed within the chamber of the bag, the mixing element being spaced apart from the flexible sparging sheet.

The apparatus further a support element which is arranged to maintain the shape and orientation of the membrane.

A regulating slide valve apparatus having a housing which forms a duct through which a gaseous or liquid medium can flow having an inlet longitudinal portion, an outlet longitudinal portion, and an adjustable regulating element for varying the flow cross section of the duct and adjusting the throughflow rate. A seat ring element is provided in the duct, the regulating element has a first longitudinal portion which has a circular cross section with diameters that vary in the longitudinal direction, and the regulating element is adjustable in the longitudinal direction of the duct along an adjustment travel. In a closure position the regulating element lies against the seat ring element and closes the duct and, in an open position, forms an annular gap through which flow can pass, with the seat ring element. The varying diameters along the first longitudinal portion of the regulating element are configured such that the change in the cross-sectional area through which flow can pass, of the annular gap with the adjustment of the regulating element in the longitudinal direction, is such that the volume flow through the annular gap varies approximately linearly with the adjustment of the regulating element along the adjustment travel.
