Abstract: A dual gas-bearing system includes a vacuum-preloaded gas bearing, a substrate, and a gas-bearing backer. The vacuum-preloaded gas bearing is mounted to a machine base in a fixed location. The substrate has a first surface facing the output face of the vacuum-preloaded gas bearing and an opposing second surface facing the output face of the gas-bearing backer. The gas-bearing is freely moveable in a direction normal to the output face of the vacuum-preloaded gas bearing. A gas flow through the output face of the vacuum-preloaded gas bearing imparts a first net force onto the first surface of the substrate, and a gas flow through the gas-bearing backer imparts a second net force onto the second surface of the substrate, wherein the second net force and the gap between the output face of the gas-bearing backer are independent of the position and thickness of the substrate.

The measuring head comprises means for generating negative pressure in the air space below the reference part, and the reference part comprises holes formed through it, in such a way that the negative pressure generated in the air space affects through the reference part the space between the reference surface and the moving web in such a way that the web is supported against the reference surface substantially over the whole area of the measuring area.

Abstract: A deflection compensated roll has a stationary support structure and a shell rotatably arranged around it by means of slide bearings. The shell is additionally supported on the support structure with hydraulic loading devices by which the axial profile of the shell can be controlled. In the procedure, at least the pressure acting in the main bearing elements of the slide bearings effective in oppsite directions in the nip plane is measured by conducting pressure data from a pressure space between a control valve associated with the main bearing elements and each main bearing element by means of measurement ducts outside the roll where the pressure data is passed to a pressure sensor.

Abstract: An ALC circuit is turned on (S1), a nozzle is shifted to a sampling position (S2), and after the ALC circuit has been turned off (S3), the nozzle is allowed to start discharging air from its tip (S4). While the nozzle is being lowered, the inner pressure of the nozzle is monitored (S5, S6), and upon detection of an increase in the pressure, the discharging process of air and the nozzle lowering process are stopped (S7), while the monitoring of the magnitude of the pressure is continued (S8). When the magnitude of the pressure is being maintained within a permissible range of the change for a predetermined time, it is judged that the tip of the nozzle has come into contact with the true liquid level, and after a suction operation of a sample (S9), the nozzle is raised (S10).

Abstract: A measuring probe in a paper measuring apparatus is kept at a distance from the surface of the paper by feeding medium between the paper and a surface of the measuring probe through a feed hole in the surface of the measuring probe. The pressure of the supplied medium, the dimensions of the feed hole and measuring probe, and the distance of the probe surface from the paper are arranged such that after the medium is discharged from the feed hole, the rate of the flowing medium increases so as to produce an underpressure, which generates a force tending to move the paper and the measuring probe toward each other. The discharge of the medium from the feed hole produces an opposite force urging the paper and probe away from each other, and the measuring probe and paper settle in a state of equilibrium determined by the two forces.
