Abstract: ABSTRACT OF THE DISCLOSURE      An improved process is provided for increasing the solids content of black liquor at its recovery in a sulphate pulping process.  According to such process, the liquor is first heated at a pressure which is so high that no boiling occurs at the heating temperature.  The liquor is then led to a tank where its pressure is released to a value below the saturation pressure of steam at the relative temperature of the liquor, such that water is evaporated, and the solids content of the black liquor is increased to 65% by weight.  The liquor thus concentrated can be led to the liquor combustion in the recovery process.

Title: Inert atmosphere control for induction heated pressure welding system
Inventor: BROLIN CHARLES A
IPC: B23K13/06
Filed: 1987-06-18
Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus is disclosed for purging air from multiple surfaces of members to be welded together. The apparatus includes a hood with the inert gas entering the hood at about 150 cubic feet per minute at between 2-5 pounds per square inch gauge when handling approximately 2 1/2 inch diameter tubes.  The gas is first evenly spread in the hood to fill the entire cross sectional area thereof and is then moved through a straightening section to provide laminar flow of the gas across the multiple surfaces.  An induction coil is moved between hood closure means into the hood to heat the weldable surfaces to a bonding temperature and after the coils have been removed from the hood, the members are urged together to upset the heated surfaces to weld the two members together.

Title: Corrosion resistant nickel alloyed ductile cast iron and method of making it
Inventor: KENT RANDY K
IPC: C22C37/04
Filed: 1987-06-30
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE           For better corrosion resistance, ductile cast iron is alloyed with nickel up through percentages of nickel that maintains the primary ferritic phase.  Through this range of nickel additions, commencing at approximately 0.2 percent, and ending at approximately 2.0 percent by weight, better corrosion resistance is obtained, while the ductility is maintained and the strength increases.  This ductile cast iron alloy is applicable for use in any industry searching for improved corrosion resistance in ductile cast iron, which is obtainable at a lower cost.  The ductile cast iron is especially applicable for use in the waterworks industry for underground applications.  The remaining composition of this ductile cast iron alloy is the composition of common ductile cast iron, including approximately by weight:  2.5-4.0% carbon, 1.7-4.0% silicon, up to 1.0% manganese, .01-.10% magnesium, up to 0.5% copper, up to 0.1% phosphorus, up to 0.7% chromium, up to .01% sulphur, up to 1.0% molybdenum, trace amounts of rare earths and other elements, with the remainder being iron and maintaining a primary ferritic phase and primary graphite structure of spheres, thus producing this low cost corrosion resistant ductile cast iron.

Title: Moisture-removal apparatus
Inventor: HATA YASUHISA
IPC: F04B39/16
Filed: 1987-11-10
Granted: 1992-05-05
Abstract: (Case No. 8446) ABSTRACT OF THE DISCLOSURE  This invention provides a pneumatic system moisture-removal apparatus wherein an end surface of an absorbent body is formed as a conical shape.  The apparatus includes an end plate approximately perpendicular to the axial direction of the absorbent body fixed on the top portion of the end surface of the cone.  A narrow space is located between the end plate and the conical-shaped end surface which serves as a passageway for compressed air.          Compressed air is supplied to the apparatus from an outside circumference of the absorbent body to the center in a radial direction.  The moisture-removal apparatus includes a honeycomb-type cylindrical absorent body having a plurality of apertures.  Compressed air is communicated into one end surface of the absorbent body in an axial direction.          Moisture is extracted as the air passes through the apertures and is discharged from the opposite end surface of the absorbent body.
