Publication number: 20170321818Abstract: An HVAC device includes a housing and a conduit tube that defines a lumen into the housing. The conduit tube and/or housing are configured such that rotating the conduit tube relative to the housing changes the direction that an outlet of the conduit tube faces. This may promote easier installation and/or maintenance of the HVAC device in the field, especially in cramped and/or poorly illuminated areas.Type: ApplicationFiled: May 5, 2016Publication date: November 9, 2017Inventors: Tom Bakken, Matthew Decker, Nathan Carlson, Brad Terlson

Publication number: 20170321819Abstract: A product may include a canister and a diaphragm may separate a control chamber within the canister. A piston may be movable in the canister between a first position and a second position in response to a pressure change in the control chamber. The piston may have a body and a skirt may extend from the body. The skirt may taper inward relative to the body as the skirt extends away from the body.Type: ApplicationFiled: May 3, 2016Publication date: November 9, 2017Inventors: RYAN THOMAS HOWELL, Brian Edward Handlon

Publication number: 20170321822Abstract: System for guiding a plurality of adjacently arranged conduits (1), which system comprises a frame configuration (2) which is configured to guide the conduits and to form a connection with an attachment surface or attachment points, wherein the system further comprises locking elements (3), which extend transversely to the conduits, wherein the locking elements are able to provide a releasable connection with the frame configuration, and wherein the system further comprises spiral locking springs (4), which extend transversely to the conduits, wherein the spiral locking springs are configured to secure the arrangement of the adjacently arranged conduits, in cooperation with the locking elements. For example, the frame configuration is a ladder-shaped frame or comprises one or more frame sections (5, 5?). The locking elements may extend on the inner side or the outer side of the spiral lock ing springs.Type: ApplicationFiled: November 2, 2015Publication date: November 9, 2017Inventors: Lars Daniel Burggraaf, Wouter Nicolas Andries Burggraaf

Publication number: 20170321823Abstract: A pipe pulling device guides extruded plastic conduit tubing through a building structure. The device has a fastener body including a main shaft supporting a resilient expansion sleeve thereon that can be inserted into an open end of the tubing. A nut is threaded onto the main shaft for axially compressing the expansion sleeve between the nut and a fastener head at the inner end of the main shaft to radially expand the sleeve within the tubing and frictionally grip the fastener body relative to the tubing. The nut is tapered outwardly and supports an elongate, rigid tip body extending longitudinally outward from the tubing to guide insertion of the tubing through cavities in the building structure. Various accessories can be secured to the nut or the tip body to assist insertion of the pipe pulling device through different building structures.Type: ApplicationFiled: April 27, 2017Publication date: November 9, 2017Inventor: Patrick George Curran

Publication number: 20170321824Abstract: A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.Type: ApplicationFiled: July 27, 2017Publication date: November 9, 2017Inventors: Joe Ott, John J. Rup, JR., Shawn Stempinski, Stanley J. Funk, Dennis M. Moura, Lexia Kironn, Roger O. Coffey
