Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus and method for digestion of cellulose material in a continuous digestion process that do not require screens in the digesting zone.  Cellulose chips and digesting liquid at relatively low temperature are introduced into a relatively long and thin cylindrical impregnation vessel, having a first diameter.  The chips from the impregnation vessel pass into a digestion vessel, having a second diameter substantially greater than the first diameter, the outlet for the impregnation zone into the digestion vessel being disposed well into the digestion vessel and below an outlet(s) disposed in the top of the digestion vessel, and form a chips column in the digestion vessel.  Digesting liquid at a relatively high temperature is introduced into contact with the chips at a point a significant distance below the impregnation vessel outlet, and the quantity of digesting liquid being introduced and the first and second diameters are so arranged that the velocity of liquid flowing to the digestion vessel top outlet is substantially less than the velocity of liquid that would entrain significant numbers of particles therein, whereby a clarifying section is provided between the chips column and digestion vessel outlet so that the need for screens at the outlet is eliminated.  A pair of vertically arranged screens which are alternately connected to a suction source may be provided in the clarifying section between the top of the chips column and the outlet to remove any particles that might be entrained in the liquid therein from the liquid.

Abstract: SPECIFICATION RICHARD R. MAKI          SPIRAL CLASSIFIER HAVING PRIMARY AND SECONDARY COARSE SOLIDS FRACTION DISCHARGE                        ABSTRACT OF THE DISCLOSURE          The dryness of the coarse solids fraction discharged from a spiral classifier is improved by the provision of a secondary coarse particles discharge in the side wall of the classifier tank upstream of the primary coarse particles discharge. Part of the coarse fraction is removed from the process stream through the secondary discharge thereby relieving the load on the raking mechanism and facilitating the liberation of entrained free moisture from the coarse material remaining in the classifier tank.

Abstract: Abstract of the disclosure:           Novel, valuable 1:2-cobalt-complex dyestuffs of the monoazo compound of formula (1)     (1) had been found, in which R1 is halogen, nitro, lower alkyl, a sulfonamide radical or a carbonamide radical, and R2 and R3 are alternatively a nitro and sulfo group.  These novel dye-stuffs are well suitable for the dyeing of natural and syn-thetic polyamide fibers, especially in admixture with hydro-phobic fibers, and also especially advantageously with other 1:2-chromium or 1:2-cobalt-complex dyestuffs containing one or two sulfonic acid groups per dyestuff molecule, yielding even, strong dyeings of high fastnesses to wet processing and to use as well as to light. - The novel cobalt complex dyestuffs can be prepared by cobalting the above monoazo compound (1) by means of a cobalt yielding agent.

Abstract: ZERO LAP VALVE                    Abstract of the Disclosure Zero lap valve includes two cylindrical valve member portions, each having passageways intersecting a bond surface thereof, and two valve body portions, each having a cylindrical cavity with radial ports intersecting the cavity and a bond surface thereof.          The bond surfaces of the valve member portions are bonded together to form a valve member having passageways in one portion bounded by the bond surface of the other portion with the passageways in the two portions interconnected.  The valve member is positioned in a valve body formed by bonding the bond surfaces of the valve body portions such that common ports in both portions have adja-cent ports to either side in different portions.  The valve member is axially slidable perpendicular to the bond surfaces such that the bond surfaces of the ports act as metering edges in coopera-tion with the bond surfaces of the passageways as the passageways interconnect one or the other of the adjacent ports to the common ports.  When and only when the bond surfaces of the valve member member are coplanar with the bond surfaces of the valve body, the valve member passageways will be blocked from the adjacent ports with zero lap.

Abstract: Abstract of the Disclosure Apparatus for aeration of water for reduction of the biological oxygen demand, which comprises a cylindrical vessel with vertical axis of selected cross-sectional area and height. A horizontal dividing wall is positioned near the bottom of the vessel.  Water enters into the space below the dividing wall and passes upwardly through a plurality of narrow slots spaced equally from each other.  An air manifold is provided including a plurality of small diameter pipes, or arms, each of which is positioned over one of the slots in she dividing wall.  A plurality of small diameter orifices are drilled on she underside of the arms, divided substantially equally on each side of the center line, so that as the water rises it is immediately contacted by she air bubbles, which issue through these orifices.  The air bubbles and liquid would rise in a column above the arms.  Near the top of the chamber is a horizontal baffle plate, which has an annular space between its outer circumference and the inner wall of the tank.  The air and water flow through the annular space, and radially inwardly, where the air dis-engages from the liquid, and flows upwardly through an axial pipe, while the liquid flows downwardly through an axial pipe.

Abstract: LINED PRESSURE VESSELS                   ABSTRACT OF THE DISCLOSURE           A method of making hollow, fiber-reinforced resin articles having a resin-rich interior coating is disclosed.  The interior coating provides a chemically resistant surface and inhibits wicking of fluids through the sidewall of the tank.  The coating is formed by positioning a hollow lay-up of loosely felted reinforcing fibers against the inner surface of a rigid mold having a cylindrical wall portion and domed end portions.          A polyester fiber surfacing fabric is placed against the inner surface of the lay-up.  The surfacing fabric and lay-up are com-pressed against the mold wall by a pressurized, inflatable core to hold the fabric and lay-up in place.  A metered amount of a thermosetting resin is injected into the mold, and the pressure of the inflatable core is increased to compress the lay-up, to evenly distribute the resin throughout the lay-up, and to form a resin-rich coating with said surfacing fabric.

Abstract: Abstract of the Disclosure Exhaust gases from diesel and some other engines vary in tem-perature from about 100°C to about 800°C.  Exhaust is passed along with ammonia to a first reactor wherein the ammonia reduces nitric oxide at temperatures down to about 260°C. At these temperatures the effluent from the reactor is passed to the exhaust.  When the first reactor effluent is at a temperature below about 260°C, it is passed through a second reactor after intermediate cooling, wherein it contacts an ammonium halide on activated charcoal catalyst at a temperature of 100°C to 170°C, which catalyst catalizes the low tem-perature reduction of nitric oxide with ammonia.
