Abstract: An assembly and method for determining the level of sound absorbing solids in a fluid-filled vessel. A number of sound receivers are mounted at spaced vertical positions to the exterior of the vessel along a generally vertical line, and a sound generator is mounted atop the vessel approximately 180.degree. around the circumference of the vessel from the receivers. The sound waves are intermittently or cyclically generated by the sound generator, they are received by the receivers, and evaluated. For those receivers mounted below the level of the solids, the energy received will be low, while for those mounted above the solids level in the fluid phase of the vessel, the energy received will be high. For cellulosic chips, the receivers are tuned to respond primarily to sound at a frequency of about 3200 Hz. Alternatively, a number of sound generators are mounted at spaced vertical positions along the vessel, and a single receiver is mounted in operative association with the vessel fluid phase, the generators being selectively actuated for given time periods, and the receiver output being displayed relative to each generator actuation.

Abstract: A high pressure transfer device for feeding wood chips to a digster in the production of paper pulp has enhanced efficiency. A pocketed rotor is mounted for rotation in a housing having first through fourth ports, with a screen at the third port for screening wood chips out of liquid passing through that third port. This screen is blanked at the leading edge in the direction of rotation so that as a pocket rotates into operative association with the first and third ports, the pocket inlet has an arcuate extent of about two inches which is exposed to the first port --large enough to allow chips to start flowing freely into the pocket--before the outlet of that pocket is exposed to a suction source in communication with the screen. A pump supplies high pressure liquid to the second port, but the second and fourth ports are constructed so that a pocket inlet--as the rotor rotates into operative association with the second and fourth ports--is not operatively exposed to the high pressure liquid from the pump until that pocket outlet is already in communiction with the fourth port over an arcuate extent of about two to three inches, allowing chips in the pocket to escape rather than be compressed by the high pressure flow.

Abstract: Immediate and accurate control of a pulp refiner is provided so as to control the degree of refining in the production of mechanical pulp, such as RMP, TMP, and CTMP. The mechanical pulp discharged from a refiner is fluidized by a fluidizing centrifugal pump, the fluidizing action instantaneously removing the pulp latent properties. A sample of the latency-removed pulp is then subjected to a pulp freeness measurement, and that freeness measurement is supplied to a computer. The computer utilizes the freeness measurement, as well as other measurements such as pulp consistency and flow rate measurements, and dilution flow measurements, and in response to the inputs control refiner parameters to ensure that the freeness of the mechanical pulp being produced is within the desired range. The refiner parameters controlled can be the hydraulic plate loading (refining pressure), and/or the tonnage of fiber supplied to the refiner.

Abstract: An apparatus and method for the digestion of cellulosic fiber material providing pulp of very uniform quality. Cellulosic fiber material entrained in treatment liquid is fed into a top portion of a first vertical treatment vessel, impregnation of the fiber material with treatment liquid taking place in the first vessel. A first flow path of fiber material entrained in and impregnated with treatment liquid is established from the bottom of the first vessel to a top portion of a separate second vertical treatment vessel, liquid substantially filling the second vessel. Liquid is withdrawn from the top portion of the second vessel (without screening) and a second flow path is established of the liquid withdrawn from the second vessel back toward the bottom portion of the first vessel, heating of the liquid during transport in the second flow path taking place. A portion of the heated liquid flowing in the second flow path is fed into the first flow path, while the remainder of the heated liquid is fed to a bottom portion of the first vessel, the bottom portion of the first vessel serving as the heating chamber. Washing as well as digesting may taken place in the second vessel, the uniform quality digested fiber material is withdrawn from the bottom of the second vessel.
