Abstract: A method of recovering ink deposits which remain in the ink drum liner of a substantially empty container which comprises the steps of positioning the mouth end of the drum liner proximate to a roller nip region of wringer assembly structure, inserting the mouth end into the wringer assembly, rotating the wringer assembly so as to draw the liner therethrough while simultaneously urging the ink remaining in the liner towards the closed end as a bulge, pulling the liner through the wringer assembly, opening the closed end of the liner to release the bulge of remaining ink deposits from the closed end of the liner, releasing the accumulated ink deposits from the liner and removing the ink drum liner from said wringer assembly structure.

Abstract: Disclosed is an improved flat plate solar collector module for use in a solar energy utilization system. Each collector has a housing with an evacuated chamber defined therein. A transparent planar wall forms one side of the chamber and a radiant energy absorber with flow passages therein is supported within the chamber thermally insulated from the housing. Heat exchanger flow conduits extend from the absorber and through the housing without contacting the walls of the housing to allow circulation of heat exchange fluid through the absorber with minimal conduction heat losses.
