Abstract: A system and a method for cleaning a printing cylinder or other printing equipment such as printing plates, ink pans or floors of printing units, the method comprising applying a detergent to the surface to be cleaned, after a period to allow action of the detergent, removing the detergent by rinsing, using a vapor and high velocity air stream, i.e. atomized water fog; or steam; or a combination of steam and air, which allows dislodging particles encrusted within cells of the surface of the piece of equipment to be cleaned.

Abstract: The disclosure herein describes a unit used in an apparatus for measuring the viscosity of a fluid contained in a recipient; the unit includes a vertically displaceable piston at the upper end of which is provided a lifting plate while the lower end is equipped with a spherical head displaceably received in a cup immerged in the fluid. As the piston is lifted, fluid is drawn into the cup. After being raised, the piston is allowed to fall under gravity and the fluid in the cup is expelled through a small clearance between the spherical head and the inner cylindrical wall of the cup. The time required for the piston plate to contact and actuate a switch is proportional to the viscosity of the fluid.
