Abstract: A method including providing a mold cavity to produce an outer contour of an acoustic resonator and providing a mold core to produce an inner contour of the resonator. The inner contour corresponds to a plenum, and a connecting channel in fluid communication with the plenum. An insert fitting adjacent to the mold core defines a length of the connecting channel during injection molding of the resonator.

Abstract: A retainer has a first ratcheting receiver that engages a strap in a one way ratcheting relationship that allows a free end of the strap to be passed through the first ratcheting receiver and a shank to be thereby pulled toward the first ratcheting receiver but not drawn away therefrom. The first ratcheting receiver backs an extension post protruding from the retainer such that the shank is sized to pass through an opening in a wall but is prevented from being withdrawn from the opening when the retainer is urged against the wall such that the extension post occupies at least a portion of the opening. A second ratcheting receiver is affixed to the retainer and receives the free end of the strap for securing a load to the retainer after the shank has been urged toward the first ratcheting receiver to secure the retainer to the wall.

Abstract: An attachment system has a strap with a shank and a free end interposed by a medial portion. A retainer has an extension post facing the shank and engaged with the strap in a one way ratcheting relationship such that retainer may be urged toward the shank but not drawn away therefrom. The shank is sized to pass through an opening in a wall but is prevented from being withdrawn from the opening when the retainer is urged against the wall such that the extension post occupies at least a portion of the opening.

Abstract: A fuel primer is disclosed. The primer includes a rigid valve body having first and second ends with first and second check valves therein. The pump also includes an elastic and substantially fuel impermeable bulb substantially encasing the rigid valve body and sealing to the valve body proximate the first and second check valves.
