Abstract: ABSTRACT OF THE DISCLOSURE                  Acid and alkaline filtrates are separated from the bleach plant of a bleached pulp mill for use in washing unbleached pulp free from entrained pulping liquor.  Acid effluent is neutralized with sodium hydroxide solution prior to use in the washing as the last washing step while alkaline filtrate is used in the remainder of the washing.  Part of both the acid and alkaline filtrates are not used in the washing to allow bleed of calcium value and caustic extraction stage solids which otherwise would build up on the washed pulp mat passing to the bleach plant.

Abstract: ABSTRACT OF THE DISCLOSURE               A rotary cutter type key cutting machine for duplicating keys in which the V-shaped notches that define the bitting are obliquely oriented both left and right.  Identical vises mounted on a hinged carrier which swings about an axis parallel to that of the rotary cutter, grip the pattern key and the key blank and present the same respectively to a position-identifying stylus and the rotary cutter.  The vises are rotatable in unison about their connections with the carrier, permitting them to be so oriented that as the carrier is swung towards the axis of the cutter, the bitted and about-to-be-bitted edges of the pattern key and the key blank are either parallel to the cutter axis or inclined with respect thereto in one direction or the other depending upon the direction the vises have been rotated.  The stylus is yieldingly projected to a position at which its key-engaging tip is spaced a distance from the cutter axis greater than the radius of the cutter, so that a selected V bit in the pattern key can be engaged with the stylus and rotary adjustment of the vises as needed to have the selected V bit fit the stylus can be effected before the key blank contacts the cutter.

Abstract: A METHOD AND APPARATUS FOR MONITORING THE AXIAL POWER DISTRIBUTION WITHIN THE CORE OF A NUCLEAR REACTOR, EXTERIOR OF THE REACTOR            ABSTRACT OF THE DISCLOSURE         A method and apparatus for establishing the axial flux distribution of a reactor core from monitored responses obtained exterior of the reactor.  The monitored responses are obtained from at least three axially spaced flux res-ponsive detectors that are positioned within proximity of the periphery of the reactor core.  The detectors provide corresponding electrical outputs representative of the flux monitored.  The axial height of the core is figuratively divided at a plurality of space coordinates sufficient to provide reconstruction in point representation of the rela-tive flux shape along the core axis.  The relative value of flux at each of the spaced coordinates is then established from a sum of the electrical outputs of the detectors, respectively, algebraically modified by a corresponding preestablished constant.

Abstract: CONTROL POINT CIRCUIT              ABSTRACT OF THE DISCLOSURE           The disclosure relates to a control point circuit for use in a telephone exchange for energizing and de-energizing a control element such as a control relay in response to set and reset input pulses.  The control point circuit comprises a transformer having a centertapped primary forming set, reset, and common inputs for receiving the set and reset input pulses and a secondary coupled to a constant control voltage.  The control point circuit also includes a comparator having a first input coupled to the transformer secondary, an output coupled to the control relay to be energized and de-energized and a second input coupled to the comparator output for receiving first and second reference voltages which are related in magnitude to the constant control voltage to maintain the comparator in the set state or reset state indefinitely until a reset or set input pulse is received.  A received input pulse causes an induced voltage within the transformer secondary which augments the control voltage to change the relation in magnitude between the reference voltages and the control voltage to cause the comparator to change states in response to the received set and reset input pulses.  When the com-parator is in the set state, the control relay is energized and when the comparator is in the reset state, the control relay is de-energized.
