Abstract: A separator device to separate a mixture of immiscible liquids of different densities wherein one of said liquids is in a discontinuous phase. The separator device includes a container having an inlet for the mixture of immiscible liquids and an outlet for removing one of the liquids after separation. A drain is provided to remove the discontinuous phase liquid after separation. Randomly arranged, loosely packed, coalescing medium within the container encourages coalescence and agglomeration of the discontinuous phase liquid.

Abstract: A dampener roller cartridge for mounting on a cylindrical support comprising a core tube having a central bore to receive the cylindrical support, the core tube being characterized by having an annular wall thickness of at least one-third the radius of the tube, and a coherent network structure providing a density of less than 0.5, the plastic substance and the network structure providing the tube with sufficient resilience to be resiliently deformed by a radially applied force by a mating roller and to recover its original shape after the cessation of the radially applied force, and further providing the core tube with sufficient rigidity to permit tight slidable mounting of the core tube on the cylindrical support, and a moisture-absorbent, outer sleeve secured about the circumference of the core tube.
