Abstract:

A disperser of a powdery cloud which may be used to defeat infra-red sens used by enemy forces and an arrangement which will effectively and efficiently produce a cloud of powder for military applications. The disperser is provided with a barrel containing powder to which a cover is secured. The cover has an axial opening provided with an upper and lower cylindrical pipe section communicating therewith. A hollow elbow-like pysi is also secured to a second opening in the cover. Air is forced into the upper cylindrical pipe and travels down through the lower cylindrical pysi into the powder. This forced air carries the powder up to the elbow-like pipe and out into the atmosphere as a powdery cloud. Control of the dispersion process is by means of two slide-valves provided on the upper cylinder pysi.

Jacob Sofinowski - Baldwin MD

Assignee:

AAI Corporation - Cockeysville MD

International Classification:

F41C 2502

US Classification:

42 50

Abstract:

A cartridge magazine having a slidably removable bottom cover which slides on a pair of flange slide rails on the bottom end of the hollow main cartridge-holding body of the magazine, to enable assembly and removal of the cover. Cam stops and end stops are formed on elastically flexible opposite side walls of the body, and are engagable in releasable locking relation by inturned lock lips which ride in sliding relation on the flange slide rails. The lock lip means are movable over the cam lock stops by depression of the flexible outer walls during assembly and removal of the cover, being cam depressed during assembly and being positively manually depressed for disassembly removal. A cartridge feed spring acts in conjunction with the curvature of the main body and a key tab on the bottom cover to exert a small removal-acting lateral force on the cover.
