Systems and methods for the detection of substances (particularly particulate substances) within mail pieces, specifically letters and other 'flats' of mail. In particular, the systems and methods are for the detection of residues of Chemical or Biological Warfare Agents (CBWAs) which may be present within the mail pieces. The system is principally designed to be included as part of Dual Pass Rough Cull System (DPRCS) for the collection and detection of the residue when the contaminated mail piece first enters a mail facility and before it is intermingled with other mail pieces. The system also utilizes aerosol chambers using at least two arrays of pinch rollers to provide for decreased incremental changes on mail pieces and decrease the likelihood of mail piece damage.

Systems and methods for residue collection

A retainer arm assembly ( ) for use in a container unloading assembly ( ) for unloading containers (C) of various sizes. Pivot posts ( ) are attached to opposite sides ( ) of a fixture ( ) into which containers to be unloaded are set. The fixture is movable to invert the container and dump its contents. Retaining arms ( ) are mounted on each pivot post and moved by the pivot posts to a position above an open end of the container. The retaining arms now retain container in the fixture as the contents of the container are dumped. A mechanism ( ) is activated to rotate each post from a first position to a second position, after the container is placed in the fixture, for the retaining arms to be located above the container. Other of the retaining arms mounted on each pivot post may contact the container as the pivot posts are rotated.
