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

A duct board system/method utilizing extruded edge interconnection strips (EIS) is disclosed. The EIS are formed to allow linkage of planar duct board sheets (DBS) in a variety of connection methodologies including right angle corner connections (RAC), planar sheet connections (PSC), planar interface connections (PIC), and surface interface connections (SIC), without the need for specialized DBS cutting tools or fabrication dies. The EIS may incorporate provisions for spaced and/or on-demand fastener connection of DBS to the EIS, provisions for ridged/lobed/edged linkage of the DBS to the EIS, as well as provisions for edge sealed linkage of the DBS to the EIS.

A unitary support assembly for connecting an air transport duct to a support includes a body portion, a duct connecting means integrally formed with the body portion for selectively securing the support assembly to the air transport duct, and a support connecting means integrally formed with the body portion opposite the duct connecting means for selectively securing the support assembly to the support.

A system and method of assembling flanged duct sections, using large sheet metal screws through opposing inserted corner plates. The large screws are threadedly inserted fully through the corner plates of a first duct section and hold perpendicular thereto for guiding alignment with the mating duct section. The screws hold the duct sections apart to allow aligning them without fluid sealant or tape gasket material on one of the duct sections contacting the other. The screws are then threadedly engaged with the corner plates of the mating duct section, bringing the duct sections together with a leak resistant seal therebetween. Optional hanger brackets can be placed between the corner plates before assembly, and additional screws used to deform the flanges and corner plates about the brackets to compress the sealant or gasket thereabout.

A coupling is disclosed providing fluidic continuity between first and second orifices of two portions of an air circuit which includes a flexible sleeve, a first frame connected in fluid-tight manner to a first end of the flexible sleeve and having a first opening, and a second frame, connected in fluid-tight manner to a second end of the flexible sleeve and having a second opening. The coupling is deformable so that the flexible sleeve may adapt to the variable spacing between two avionics racks and is able to compensate for a misalignment between the orifices of two portions of an air circuit.

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

A connector has five or six abutment surfaces for cable ducts. The cable ducts may have substantially square end faces or rectangular end faces half as large. The connector has a main body made of metal, which exhibits one or two square abutment surfaces or portions thereof, and which exhibits four smaller substantially rectangular abutment surfaces.

A connection system of piping for distribution systems of pressurized or depressurized fluids, the system including: a connection joint having an insertion portion insertable in the piping so as to seal it and a retention portion, projecting therefrom when the joint is inserted therein; a retainer suitable to longitudinally retain the connection joint to the piping, said retainer including: i) a retention element which engages the retention portion for constraining the joint longitudinally; and ii) clamping element adapted to exert a clamping force to lock the retention element to the piping.
