Title: A Method and Device for Achieving High Purity and Whiteness in Cellulosic Pulp

Abstract: 1,177,768. Separating wooden chips. R. ZEMANEK and M. CARSKY. 22 Dec., 1966 [24 Dec., 1965], No. 57399/66. Heading B2H. [Also in Division D2] In a process for the elimination of wooden impurities from cellulosic pulp, wooden chips after their delignification are passed in an aqueous suspension on a set of rotary bodies so as to separate according to their width chips of a required size from chips exceeding that size. After delignification e.g. by boiling with Ca bisulphite or Na bisulphite or sulphate, pulp from a pit or rinsing filter (not shown) is fed to a box 1 from which it overflows on to a first inclined set of rotary rolls 3 revolving in the same direction and at the same angular velocity with a constant gap 4 maintained between adjacent rolls. Relatively pure chips of a required size fall through the gaps 4 on to a stationary screen 6 of a thickening or dewatering device 5 where removal of water takes place by means of rails 7 which are mounted transversely between endless chains 8 and wipe against the upper and lower surfaces of the screen. The coarse impure chips and knots are delivered to a vortex defibrator 9 where, due to the turbulence created by a rotary conical screw 11, the relatively pure surface layer of the chips is peeled off from the dark impure inner layer. The mixture obtained overflows through a pipe 12 on to a second set of rotary rolls 13 having between them gaps 14 of smaller dimension than the gaps 4 of the first set. The relatively pure chips passing through the gaps 14 are passed with the first lot of pure chips into a dewatering apparatus and thence to a defibrator. The mixture of coarse impure chips and knots discharged from the set of rolls 13 may be fed by a screw conveyor to a knot mill. The rolls 3, 13 may have a crosssection in the shape of a circle, a spherical triangle, or a spherical pentagon.

Title: Maximum and minimum signal selectors
Inventor: GRAY FREDERICK MARTIN

Filed: 1968-12-06
Abstract: 1,241,454. Selecting the maximum or minimum signal. ENGLISH ELECTRIC CO. Ltd. 6 March, 1970 [6 Dec., 1968], No. 58083/68. Heading H3T. [Also in Division H2] The maximum or minimum amplitude signal of a number of input signals is selected by applying the signals to the input transistor of a respective transistor long-tail pair and applying negative feedback from the common output to the other side of the pairs. As shown the longtail pairs have respective input transistors TR1A-TR1C and a common transistor TR2, the output being fed back negatively via TR5 to the base of TR2. The one of transistors TR1 receiving the largest input signal robs the other TR1 transistors of their share of the constant emitter current provided by R3 and the feedback to TR2 maintains the current in TR2 almost equal to that in the conducting transistor TR1. If two or more signals are equal the current is shared by a corresponding number of the conducting transistors TR1 and the base emitter voltages are thus less than that of TR2 thereby introducing an error. This may be overcome by using independent long tail pairs (Figs. 2 and 3, not shown), Fig. 3, using transistors of the opposite conductivity type and thus selecting the minimum signal.
