Abstract: An inker for a printing press in which an excess of ink is applied to the surface (45) of a resilient roller and the ink is metered by a metering member (10') to form a film of controlled thickness on the resilient roller surface. The metering member is a long strip including a polished metering surface and a polished support surface (26) which intersect to form a polished metering edge (25), the polished support surface (26) intersecting with a polished trailing surface (28a) to form a polished trailing edge (28b). The metering edge (25) and trailing edge (28b) are closely spaced such that the entire support surface is indented into the resilient roller surface for metering a film (130) of ink and for assuring that the ink will separate cleanly from the metering member at the trailing edge (28b).

Abstract: An apparatus and method to saturate a fibrous web. The apparatus comprises a sealed chamber divided to form a low pressure preparation zone and a high pressure treatment zone. Air is evacuated from the open area between the fibers in the web in the vacuum zone and liquid in the treatment zone is forced into the evacuated open area between the fibers in the web. A pair of nip rollers are submerged in liquid in the treatment zone for squeezing residual air and liquid from the open area between the fibers in the web to cause liquid to be drawn into the open area between the fibers in the web upon exiting the nip between the rollers.

Abstract: Aircraft attitude along the pitch axis is controlled by inputting a velocity command to a pitch control subsystem that includes a velocity side channel and a gain side channel of a pitch servo amplifier. An output from each channel of the pitch servo amplifier is applied to a pitch servo motor for positioning a primary control surface. The velocity of the pitch servo motor is detected by a velocity detector that generates a velocity feedback signal and control signals for each channel of the pitch servo amplifier. Also responsive to the velocity signal of the detector is a pre-flight test circuit for pre-flight checkout of the pitch control subsystem. In each line from the output of the channels of the pitch servo amplifier is a current detector that is part of a pitch trim control subsystem that responds to the current through the pitch servo motor to generate a trim velocity command signal. This velocity command signal is input to a velocity side channel and a gain side channel of a trim servo amplifier.

Abstract: A method and apparatus for continuously using ink and dampening fluid in a printing system includes removing ink and dampening fluid from a form roller after the form roller engages the printing plate. Mixing of the removed ink and dampening fluid to form a substantially homogeneous printing liquid is accomplished by circulating the removed ink and dampening fluid to a reservoir where it is mixed with ink in the reservoir by an auxillary blender. The homogeneous mixture is further circulated to the center of a metering nip between two rollers and flows longitudinally of the rollers at a rate to prevent separation of the dampening fluid from the ink. Unused printing ink and dampening fluid is returned to the reservoir with the ink and dampening fluid removed from the form roller.
