Abstract: ABSTRACT OF THE DISCLOSURE         A torque measurement system for measuring shaft torque has two toothed wheels mounted in spaced apart relationship.          Each of the wheels has a plurality of axially extending spaced teeth along its periphery extending into spaces between the teeth of the other, forming an interlaced array of teeth having tooth spacing interstices therebetween.  A discontinuity is provided in the tooth pattern at at least one location around the periphery of the two wheels to serve as an index marker.   A single detector such as a variable relunctance sensor is mounted proximate the wheels to provide output signals repre-sentative of circumferential widths of tooth spacing inter-stices and also representative of the index marker.  The widths of the interstices change upon shaft torque deflection, and signals from the sensor are processed to produce a DC signal proportional to torque.  The two wheels can be offset in a no load condition so that adjacent tooth spacing interstices are approximately equal in a torque deflection range of interest.

Abstract: A B S T R A C T The present invention relates to a method for producing alkali-metal selenite and alkalimetal selenate from metallic selenium through selenious acid.  The selenium is dissolved in nitric acid to form selenous acid, which is reacted with an alkalimetal base, to form alkalimetal selenite.  The formed selenite is then spray dried.  Alternatively, the formed selenite is oxidized at elevated temperature in a basic environment at pH 10-12, with hydrogen peroxide as the oxidant, to form selenate, which is then spray dried. The invention also relates to products produced by the method.  The products are intended to be incorporated in animal-fodder or foodstuffs (selenite), or in fertilizers (selenate), to be thus administered to human beings and animals as trace substances.

Abstract: Abstract of the Disclosure A paper-sheet dividing apparatus has a blade wheel which has a plurality of curved slots.  Each curved slot is rotated to sequentially deliver a paper sheet to a conveyor belt.  The apparatus also has a dividing member rotated together with the blade wheel and timed such that a corresponding curved slot for receiving the last paper sheet among the first predetermined number of paper sheets to be divided is axially matched with one of the first blades which is positioned between the curved slot which receives the first paper sheet among the second predetermined number of paper sheets and the curved slot which receives the last paper sheet described above.  The dividing member is rotated through a predetermined angle and is separated from the blade wheel.  During this movement, the paper sheet removed from the blade wheel is temporarily supported on the dividing member.  Therefore, the paper sheets previously removed from the blade wheel and piled on the conveyor belt can be transferred without interrupting the operation of the blade wheel.  After transfer of the previously removed paper sheets, the paper sheets on the dividing member can be transferred to the conveyor belt.

Abstract: Abstract of the Disclosure There is provided a zymogen of plasminogen activator which is produced by culturing human kidney cells in a culturing medium and recovering from the culture fluid by affinity chromatography using a column of immobilized anti-zymogen antibody.  The zymogen is a polypeptide having a single chain with a molecular weight of about 50,000.  Although the zymogen itself little exhibits plasminogen activator activity, it mani-fests a significant plasminogen activator activity by catalytic amounts of plasmin.  The zymogen has a throm-bolytic ability as high as three times that of a human urinary urokinase, and the zymogen is usable for treating human thrombus.  The zymogen can be stabilized by the addition of albumin and thus its stable liophy-lized preparation can be prepared.

Abstract: SAWDUST PUMPING AND PROCESSING               ABSTRACT OF THE DISCLOSURE          A method and apparatus are provided for effecting treatment of sawdust to produce paper pulp in a simplified and efficient manner.  The sawdust is entrained with liquid so that it forms a slurry having a consistency of between about 10-25%, and preferably between about 15-22% solids.  The slurry consistency is maintained generally constant throughout the treatment process.  The slurry at that consistency is pumped by a fluidizing, high speed, degassing, centrifugal pump (22).  The pumping action alone provides for transport of the slurry to a digester vessel (26, 40, 46).  The digester vessel may be an upflow vessel (26, 46), a hydraulically filled downflow vessel (40), or a superatmospheric vapor phase downflow vessel (40). Kraft pulping may be practiced in the digester, or a sulfite process may be practiced in the digester (46) and the slurry then passed to a refiner (48) to produce a mechanical pulp.  Between the pump and the digester the slurry passes through a heating device (24, 30), which may comprise a fluidizing mixer (24) for directly introducing high pressure steam into the slurry, or a pressure diffuser (30) for effecting indirect heating of the slurry.
