Abstract: SEPARATION OF DENSE IMPURITIES FROM A FLUID     ABSTRACT OF THE DISCLOSURE An apparatus and method for removing dense impurities, such as sand, from a fluid, such as liquids use in the production of cellulosic pulp.  A verti-cally upstanding tank substantially circular in cross-section is provided includ-ing a top wall, bottom wall, and side wall.  The fluid with dense impurities is introduced into the tank with a whirling motion.  Vertical stagnation of the dense impurities against the side wall interior (which can result in damage to the tank wall) without dampening the whirling motion imparted to the fluid is pre-vented by mounting a perforated funnel in the tank at the area of the tank where the vertical stagnation is likely to occur.

Abstract: D 23,092 SWITCHED CAPACITOR BILINEAR RESISTORS by Man Shek Lee ABSTRACT OF THE DISCLOSURE     A two terminal circuit comprising a capacitive element (with a negative capacitance of of value -C/2) connected between the terminals, and an integrated capacitor (with a positive capacitance C) having one and other sides thereof alternately or periodically connected to associated sides of the element and to ground for simulating a floating bilinear resistor having a resistance R = T/C across the terminals which satifies the bilinear transformation      .  This circuit is insensitive to both top and bottom plate parasitic capacitance effects associated with the capacitance when one terminal is connected to a voltage source and the other to a virtual ground point on the input to an operational amplifier.          In alternate embodiments, the circuit simulates a grounded bilinear resistor when only one of the terminals is connected to ground, and when one terminal and one side of the capacitor are grounded.  In many application the negative capacitive element may be absorbed by a positive capacitor of larger capacitance that is connected in parallel with it in a switched capacitor circuit.

Abstract: ABSTRACT         The present invention relates to a lubricant for use in the drawing and ironing of black plate steel during the manufacture of enclosed containers such as cans.  In particular, the lubricant is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body.  The lubricant comprises an aqueous solution of an active component, such as a major portion of molybdenum disulfide, together with minor amounts of waxes and other materials.         In performing the method of the present invention, a lubricant system is employed.  The lubricant system comprises a dual lubricant coating.  The first, or outside, coating is applied to that portion of the black plate steel which ulti-mately becomes the outside surface of the can body.  The outside coating is applied, such as by spraying or gravure or offset printing, at a rate of about 25 to about 200 milligrams per square foot of steel surface.  This coating is dried, as through the use of a heat source, such as infrared heat or hot air.  A second, or inside, coating is applied to that portion of the black plate steel which ultimately becomes the inside surface of the can body.  The inside coating may also be applied to the surface of the black plate steel in a manner similar to that used for the application of the outside coating.  After the can body is produced, the outside and inside lubricants must be totally removed.  Such removal may be achieved by washing the can bodies in an alkaline solution (pH about 7.5 to 11.5) having a temperature of about 140° to about 160° F.
