Abstract: A pelletizer for liquid polymers in which the severed pellets fall from cutter knives into an annulus on the surface of a body of cooling liquid. The annulus is defined by said surface and the confluence of a downwardly flowing ring of the cooling liquid and a downwardly and radially outwardly flowing cascade of the cooling liquid. The velocity and trajectory of the pellets are controlled by the projection of a spray of cooling liquid radially across the dies from which the pellets are severed. Band heaters in proximity to the dies maintain the polymer in a liquid state prior to extrusion.

Abstract: A machine for automatically producing a sandwich having a variety of fillers such as sliced meat, sliced cheese, shredded lettuce, and sliced pickles. A plurality of cannisters for storing the fillers are positioned above apertures formed in the base of the machine along a straight row. Dispensing means associated with each cannister permit selective removal of sandwich filler. A carriage having support means for carrying the sandwich facing, such as a submarine roll or Pullman bread, is mounted for reciprocation beneath the row(s) of apertures. As the carriage passes beneath selected apertures, sandwich filler is dispensed through the apertures onto the sandwich facing. Control means permit user selection of sandwich fillers and controls operation of the dispensing means and movement of the carriage beneath the apertures in accordance with user selection.
