An adjunct part can be secured to a host part, where the host part defines a recess configured to allow a threaded fastener to secure the host part to a further part. The adjunct part has a resilient boss projecting therefrom and adapted to enter the recess, the boss having an axially extending opening to receive a threaded tightening member. The boss and the threaded tightening member have configurations which allow the tightening member, as it advances into the boss along the opening, to resiliently urge portions of the boss radially outward into binding contact with the interior of the recess, thereby fastening the adjunct part to the host part.

A unitary gasket component is designed to provide a complex acoustic path for bringing sound to a microphone. The path includes a pre-plenum and apertures to allow external sound into the pre-plenum. The path further includes an acoustic filter communicating with the pre-plenum and defining relatively small openings for sound to exit the pre-plenum. A voice tube extends from the acoustic filter to a microphone plenum, the latter being in direct communication with the microphone.

Complex acoustic path and gasket for use with microphones

A flat, substantially transparent lens lying in a flat plane retains a designation card within a recess in a surface. The lens is made of flexible sheet plastic with means at either end for securing the lens in the recess. At one end, a tab is integral with the lens and has an attachment end which joins the lens. The tab extends away from the plane of the lens to a geniculation spaced from the lens plane. At the geniculation, the tab reverses direction and extends toward the lens plane to return generally to that plane, where it terminates in a finger grip.
