Abstract: An air duct assembly attachable to a receiving port includes an air duct with an inner surface and an exterior surface connected to one another at a coupling fixture. A seal is connected and bonded to the coupling fixture. The seal extends axially from the coupling fixture and has a tip with an inner diameter smaller than the coupling fixture's inner diameter. A shell is connected to the coupling fixture and the seal. The shell extends axially from the seal and is connectable to the receiving port.

Abstract: A clean air duct and retaining clip assembly for installation on a receiving port includes a tubular body, and a cuff, which extends from the tubular body, that includes a collar, a retention groove adjacent the collar, and a sealing section adjacent the retention groove. A retaining clip is received around the cuff and has at least one inwardly extending cuff strut received therein to hold the cuff on the receiving port and isolate the sealing section, which is also received on the receiving port, from forces applied to the tubular body. The retaining clip includes an arcuate clip body with an external surface opposite an internal surface connected by opposed edges. At least one pair of struts extends inwardly from the internal surface, where one of the struts is proximal one of the edges and the other is proximal the opposite edge.

Abstract: In one embodiment, this disclosure describes a method for removing flashing from an article. The method includes the steps of configuring a deflashing apparatus in a loading condition; loading the article into a nesting portion of a first nesting plate of the deflashing apparatus; engaging an actuating mechanism to actuate a drive assembly of the deflashing apparatus; continuing to engage the actuating mechanism to facilitate movement of a press plate of the deflashing apparatus toward the first nesting plate; releasing the actuating mechanism to retract the press plate, and returning the press plate to the loading condition. During this method, the press plate compresses against the first nesting plate such that flashing of the article is separated from the article. The deflashing apparatus can include interchangeable nesting plate to fit various articles.

Abstract: A method for manufacturing an air duct includes providing a tubular body having at least one open end which is inserted into an internal cuff mold to form an internal cuff that is secured to and axially extends from the tubular body. The tubular body and the internal cuff are removed from the internal cuff mold and then inserted into an external cuff mold to form an external cuff that is secured to and radially extends from at least the internal cuff. The tubular body with the internal cuff and the external cuff is then removed from the external cuff mold.

Abstract: An air duct system for transferring air or the like from one component to another includes a tubular body with an exterior surface, an interior surface, and an end which connects the exterior surface to the interior surface. The end has a diameter no larger than the exterior surface. The internal cuff connects to the exterior surface and extends axially from the end of the tubular body. The external cuff connects to the internal cuff and the exterior surface, and extends axially and radially from the internal cuff and the exterior surface. The external cuff is made from a material relatively harder than a material used for the internal cuff.

Abstract: A clean air duct and retaining clip assembly for installation on a receiving port includes an assembly with a tubular body and a cuff extending from the tubular body. The cuff has a cuff groove, at least the cuff receivable on a receiving port, and a retaining clip only partially received in the cuff groove so as to secure the cuff and the tubular body to the receiving port. A clean air duct assembled to a receiving port is also disclosed. And a related method of assembling a clean air duct to a receiving port with a retaining clip is disclosed.

Abstract: A ported tubular air duct and a method for manufacturing a side-ported tubular air duct. The air duct has a side port located substantially ninety degrees (90.degree.) to the part line of a mold in which the air duct is manufactured. The mold has two portions which are separated when the mold is opened to permit the positioning a preheated polypropylene tubular port insert member into an opening in one of the mold portions. A parison of rubber modified polypropylene is injected into the mold between the portions at approximately 410.degree. F., and the mold is closed to seal the ends of the parison. The interior of the parison is pressurized to a level in the range of approximately 90 to 100 psi to force the parison outward against the inner sides of the mold cavity and against one end of the port member. At this juncture, the parison has a thickness in the range of 0.060 to 0.090 inches.

Abstract: A clean air duct (300) comprises a pair of tubular bodies (302, 310), each tubular body having a pair of opposed ends (304, 306, 312, 314), one of the opposed ends of one tubular body having an annular ring (346) which terminates at an inwardly extending lip (340), the other tubular body having an outwardly extending rib (322) at one end; and a cuff (320) connecting the outwardly extending rib and the inwardly extending lip. Another clean air duct (400) comprises a first blow molded tubular body (406) having a first open end (408) and an annular ring (450) which terminates at an inwardly extending lip (444), and a second blow molded tubular body (402) which has an open end (404). A cuff (412) connects the blow molded tubular bodies to one another wherein the lip (444) exerts a compressive sealing force around the second tubular body (402). Both tubular bodies (402, 406) extend from the cuff (412) in the same direction.
