Abstract: A breech release for a shotgun includes a push button, a return spring, a spring retainer, a threaded steel rod, and a release slide. the return spring is located between the push button and spring retainer. when the breech release engages with a breech, the breech release bisects an outer breech which hinged an inner breech, holding the breech closed in its default position. When the button is depressed, the button moves the slide out of the inner breech, allowing the breech to open.

Abstract: An optical interconnect assembly includes an optical coupling component having a body formed of a polymer material. The body has a reflecting surface defining a first focal point and a second focal point, a first focal surface generally aligned with the first focal point, and a second focal surface generally aligned with the second focal point. The first focal surface and the second focal surface are spaced apart and at an angle to each other, and an optical path extends through the body from the first focal point to the reflecting surface and to the second focal point. An optical source from which a light signal is transmitted is positioned adjacent the first focal surface and an optical target at which the light signal is received is positioned adjacent the second focal surface.

Abstract: An improved molding apparatus and method includes an adjustable mold component and a fixed mold component for molding precision articles; a bias force mechanism for applying a bias force to the adjustable mold component; and an adjustable mold component fine position adjustment mechanism operable exteriorly of the mold for applying a position adjustment force to the adjustable mold component to overcome the bias force and thereby adjust position of the adjustable mold component relative to a fixed mold component to reduce positional offset in a range of ±ten microns, or less, in at least one adjustment dimension. In one aspect, a plurality of bias force mechanisms and adjustment mechanisms provide positional adjustment in a plurality of adjustment dimensions. In another aspect, a feedback control loop responsive to optically sensed positional error automatically reduces positional offset.
