Abstract: PROCESS CONTROL METHOD            ABSTRACT OF THE DISCLOSURE The invention is centered on the discovery of a straight line relationship between sodium ion content and total dissolved solids in the liquor or washer filtrate from a sodium based alkaline pulp treatment stage. Sodium concentration can most conveniently be determined by the use of sodium ion selective electrodes. The relationship holds true in any stream within a given generalized system; e.g., a brownstock washer system or the washer following a caustic extraction stage in a bleach sequence. The dissolved solids information can be used as input for process control. As one example, the drop leg on the final stage of a brownstock washer system can be instrumented and used to control shower water. This enables the system to turn out a washed product in which the residual dissolved solids are held within close limits. An Important co-benefit lies in the uniform composition of the washer filtrate and the corresponding weak liquor stream to the recovery system evaporators. An Instrumented brownstock washer can also provide feed forward information and control to a bleach plant or brown paper sheeting operation.

Abstract: TEST POINT MOUNTED VOLTAGE MONITORING SYSTEM             Edmund O. Schweitzer, Jr.             Abstract of the Disclosure A voltage monitoring system for mounting on a test point in an AC power distribution system provides an output when the voltage level on a conductor is above a predetermined minimum level.  Within a sensing unit mounted on the test point a rectifier circuit develops from a capacitive coupling to the monitored conductor a voltage dependent on the voltage level of the conductor.  A potentiometer applies a portion of the voltage to the gate of a MOSFET transistor, which actuates a reed-contact relay to control external switching circuitry,  The potentiometer is user-adjustable from the front of the sensing unit to enable the minimum threshold level to be set.

Abstract: ABSTRACT      An optimizer-code generator for use in a data base system.  The optimizer-code generator employs a component called a scan analyzer for performing implementation-dependent analysis and providing implementation-dependent query code.  The optimizer-code generator receives a query in logical tree form.  It first-optimizes the logical tree.  In so doing, it provides infor-mation from the logical tree to the scan analyzer, which specifies what methods are available for accessing informa-tion required for the query and what each of the available methods costs.  The optimizer-code generator uses the cost information in its optimization of the logical tree and specifies the access methods to be used in the logical tree. The code generator then uses the logical tree to generate query code.  In so doing, it provides the specifications of the access methods to the scan analyzer, which returns query code for the access method.  The code generator then incor-porates the query code for the access method in the query code which it generates from the logical tree.

Abstract: ABSTRACT  (Fig 2) METHOD OF ANALYZING VIBRATIONS FROM   A DRILLING BIT IN A BOREHOLE      Information on tooth wear is obtained from the frequency distribution spectrum of a vibrational quantity influenced by the impact of cutter teeth onthe bottom of a bore.  In the illustrated example spectra are obtained from the product of torque and torsional acceleration and tooth wear is indicated by the shift upwardly in frequency of a pronounced peak occurring at T1 for a one eighth worn bit and at T5 for a five eighths worn bit.  Other quantities which may be used, singly or together to enhance spectral inforamtion, are weight on bit, vertical acceleration, transverse acceleration, standpipe pressure.  Abrupt changes in frequency distribution curves indicate abrupt occurrences such as broken teeth or stuck cones.  A stuck cone is also indicated by unidirectional peaks in a plot of torsional acceleration against time.
