Abstract: FIELD: logging. SUBSTANCE: prior to deflecting properly positioned stops 28 and 36 by full-length logs, the stops are initially held in the preset positions only under the gravity forces and are used as freely movable nonload-bearing indicating flags of the stops. As soon as the stops begin to deflect piston, cavities are separated from return line. The moving full-length logs are subjected to progressively increasing counteracting force developed by stops 28 and 36, which at this stage serve as partially load-bearing stops. Simultaneously with beginning of deflection of the stops multi-gear drive is shifted in intermediate reverse gear, thereby intensifying retardation process. Under the effect of the multi-gear feed drive the logs return backwards for a short time, the stops become pressed against the forward faces of the full-length logs and follow their movement. The command is then given to the multi-gear drive for moving the logs at a low speed forward and for operation of the stops as load-bearing ones. Measurement with stops is performed for logs with close tolerances. After engagement of the full-length logs with freely standing stops 28 and 36 serving as signalling flags, for the remaining logs the measurement commences in response to commands of pickups 40 and 50 of the distance covered by timber materials as a function of time. This measurement may also be performed by means of pickup and pulses counter in response to commands of which the lengths of the logs are measured with the stops disengaged. EFFECT: extended operating capabilities. 17 cl, 15 dwg

For better accuracy, use is made of push-pull mode of measurement of phase shifts brought in by communication line and by delay element connected in series with the latter that provides for elimination of methodical error due to delay of fixed low-frequency signal when it is transmitted over communication line towards central station. EFFECT: high accuracy of phasing-out while using single communication line. 2 cl, 5 dwg

Granted: 1994-06-30
Abstract: FIELD: automatic control systems. SUBSTANCE: output signal of controlled object is measured, and control action is may be periodically changed discretely according to results of measurement. The first and the second constant test actions are applied to object under control, and after alternate output of the object is carried out to corresponding steady modes, values of output signal are indicated. Then the average value is determined from these values, and the first test action is applied at preset moment of time. After that output signal is inspected and moment, when signal becomes equal to predetermined average value, is registered. As a period of change in control action the value is chosen, being equal or larger than difference between fixed and preset moments of time. When object is subjected to the second steady mode, monotonicity of change in output signal is controlled. If it is disturbed, the process may be repeated by taking the second test action as the first new one. EFFECT: improved quality of control. 2 cl, 2 dwg

Granted: 1997-09-10
Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop (38-40) in a continuous digester (19). Optimum results are obtained when kraft white liquor is also added to a recirculation loop (28-30) at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material. About 5-20% of the total white liquor necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation. The temperature in the wash zone is maintained at about 140-175 DEG C. <IMAGE>
