Apparatus for inspecting containers for foreign matter so as to insure the same being free of such matter that could affect the contents when the containers are filled, such apparatus incorporating an inspection system in which a prism is able to rotate non-collimated light without introducing distortion since it does not depend on plane wave fronts and is thus able to greatly expand the field of view, thereby providing more dependable detection of foreign matter at the center and in the peripheral areas of container bottoms and lower side walls.

Container inspection apparatus

A container crown ring chip detector applying opto-electronic means for detecting the presence of chips in the container crown ring finish consisting of support means straddling the path of travel of the container crown ring, photo elements in opposing alignment and surrounding a substantial portion of the crown ring inspection station, electronic control means driving photo emitters which emit inspection rays detected by cooperating photo transistor receivers, and sequential driver circuits and synchronous detector circuits.

A carburetor is disclosed which includes a supplementary fuel/air supply circuit for bypassing a throttle valve to provide a fixed fuel/air idle mixture. The supplementary fuel/air supply circuit includes separate fuel and air passageways which join at a mixing intersection. The mixing intersection communicates with a main bore of the carburetor at a point below a throttle valve thereof. The supplementary fuel/air supply circuit also includes a piston valve, which is responsive to manifold vacuum, to control flow of air through the air passageway so that the air passageway is open during periods of high manifold vacuum but closed during periods of low manifold vacuum. An idle-mixture adjusting screw is provided for adjusting air flow through the air passageway; a piston-stop adjusting screw is provided for tuning the position of the piston valve at its 'closed' position; and, in one embodiment, a special plug is provided for holding the piston valve in a piston chamber.
