Abstract: A hydraulic pump or motor includes a mounting flange that is disposed at the first end of the housing. The mounting flange defines a pair of bolt receiving slots that are disposed along the X-axis on either side of the shaft. The pair of bolt receiving slots each define a radius center that are spaced away from each other a X dimension, and a pilot projection extends longitudinally away from the mounting flange, defining a pilot projection diameter. A ratio of the X dimension to the pilot projection diameter ranges from 1.1 to 1.5.

Abstract: An apparatus comprises a selected volume detector that detects a selected output volume; an analog output signal amplifier; a digital volume amplifier; a boost gain control element coupled to the selected volume detector; the analog output signal amplifier; and the digital volume amplifier; wherein the boost gain control element is configured to: keep a gain of a path of the digital volume amplifier and the analog output signal amplifier substantially constant, wherein the boost gain control element can adjust both: a) a gain of the digital volume control; and b) a gain of the analog output signal amplifier; to keep the gain of the path of the digital volume amplifier and the analog output signal substantially constant and equal to the selected output volume.

Abstract: The invention relates to the movement of a web through a printing machine.The web is caused to move forward during each cycle, alternately at the printing speed during printing and at a take-up speed which is at most equal to the printing speed, the excess length arising from the difference between the printing speed and the take-up speed, in the case where the latter is less than the printing speed, being re-absorbed by pulling the web backwards without stopping the web. A typical device comprises, downstream of the printing cylinder 2, a first endless rotary member 9 for conveying the web at the printing speed, and a second endless rotary member 12 for conveying the web at the take-up speed.Application to paper in the form of webs of widely varying substances and quality.
