Abstract: A method and apparatus for controlling the heating of adsorbent materials in a vessel including the utilization of electrodes in direct contact with the adsorbent material to induce a current in the material. The electrical contacts are spaced apart and receive a potential for inducing the electrical current; one of the electrodes is a different size to thereby induce a radial component in the electrical current to thus modify the current density flowing through the adsorbent material as the current traverses the distance between the electrodes. The resulting modified current density causes the temperature gradient across the transverse section of the vessel to decrease, thus rendering the temperature more uniform across the vessel.

Abstract: A press felt for use in a papermaking machine. The press felt includes a base fabric having a batt of fibers secured to at least an upper surface of the base fabric, and preferably to both sides of the base fabric. The base fabric has a plurality of noncircular synthetic monofilament warp or machine direction ends and a plurality of shute or machine direction ends interwoven therewith according to a predetermined weave pattern.

Abstract: A press felt for use in a papermaking machine. The press felt includes a base fabric produced of polybutylene terephthalate having a batt of chlorine resistant fibers secured to at least an upper surface of the base fabric, and preferably to both sides of the base fabric. The base fabric preferably has a plurality of noncircular monofilament warp or machine direction ends and a plurality of round monofilament shute or machine direction ends interwoven therewith according to a predetermined weave pattern.
