Abstract: A method and device for removing water from a paper or board web and for passing the web as a closed draw from a forming wire or transfer wire of the web former to the press section and through one or more dewatering press nips in the press section. The web that runs on the forming wire or transfer wire is made to adhere in a transfer and pre-press zone to an outside face of a transfer belt which is substantially non-water-receiving. After this pre-press zone, the web is separated substantially immediately from the wire and passed on support of the transfer belt onto the next press fabric in the press section and/or into the next press nip. In the pre-press zone or zones, a substantial amount of water is removed out of the web substantially in one direction only, and, at the same time, the web is made to adhere reliably to the outside face of the transfer belt.

IPC: C10G49/26

Granted: 1996-11-05
Abstract: The inventive procedure more accurately maintains an inventory of a catalyst in an ebullated bed of a reactor in an oil refinery, especially a  resid hydrotreating unit.  The ebullated catalyst bed has therein three phases (catalyst, oil, gas).  A first density measurement is made of the two-phase mixture in a freeboard zone i.e. of gas and oil in a catalyst free area above the ebullated catalyst.  A second density measurement is made in the catalyst bed where all three phases are present.  Density measurements are used, along with predetermined values for vapor, liquid, and soaked particle densities and corrections for gamma-ray absorption coefficients, in order to calculate the catalyst particle holdup in the vessel.  From this, the amount of catalyst actually in the reactor can be calculated.  Once this amount is known, fresh catalyst may be added to or spent catalyst may be removed from the reactor in order to maintain a fixed catalyst inventory within the catalyst bed.

Title: Method for monitoring fiber tension
Inventor: SMITH GREGORY E
IPC: C03B37/025
Filed: 1991-09-30
Granted: 2003-03-25
Abstract: A non-contact method for monitoring the tension in an optical waveguide fiber during drawing is provided. The motion of the fiber is sensed in a direction transverse to the direction in which the fiber is moving. The sensed motion is analyzed to determine a plurality of frequency components thereof, each frequency component having a magnitude, and one of the components constituting the maximum magnitude component. The frequency of the maximum magnitude component is doubled to obtain a doubled frequency. The presence of a frequency component near the doubled frequency is ascertained to verify that the maximum magnitude component is the principal harmonic frequency of motion of the fiber. The tension in the fiber is then determined Pram the verified principal harmonic frequency component.
