Title: Water-soluble self-acid-blending polyaniline, its blends and process for making
Inventor: CHEN SHOU-AN
IPC: C08G61/12
Filed: 1996-11-19
Granted: 1999-11-21
Abstract: A process for directly preparing water solution of ortho-sulfonyl-substituted polyaniline (blended) and its blends which includes: dissolving ortho-sulfonyl-substituted polyaniline in NaOH, purifying it by dialysis through a semi-transparent membrane, then converting the salinized (deblended) ortho-sulfonyl-substituted polyaniline water solution into acidic (self-acid-blending) ortho-sulfonyl-substituted polyaniline using H+ ion exchange resin. The resulting water solution is highly stable that doesn't precipitate in a period of two years, and can be directly cast into film or coated on substrate after condensation. Its conductivity can reach 10<SP>-2</SP> to 10<SP>-3</SP> S/cm. By further blending this self-acid-blending ortho-sulfonyl-substituted polyaniline solution with water-soluble polymer or polymer emulsion, blends having enhanced mechanical property and substrate adhesion can be obtained.

Title: Heavy metal separator
Inventor: WATTS DAVID L
IPC: B03B7/00
Filed: 1986-12-11
Granted: 1990-11-06
Abstract: Abstract A heavy metal separator for removing heavy metal particles and flakes from ore. It has a feed hopper which feeds a slurry of ore over an inclined screen in a separation chamber. The smaller particles pass through the screen into a second section of the separation chamber. The larger particles wave downwardly off the lower end of the screen into a first section of the separation chamber.  A stream of water is directed by baffles upward through the second section counter current to the flow of materials. The water washes the less dense waste material out of the second section into the first section. The fine heavy metal particles and flakes, being more dense, settle downwardly to a collection point at the bottom of the second section. The larger concentrates and fine waste material move downwardly through the first section to an outlet, where they pass into a second separation chamber. An upwardly moving stream of water in the second separation chamber washes all waste material out of the separator while allowing the more dense coarse heavy metal particles and flakes to move downwardly through the water into a collection point at the bottom of the second separation chamber.

Abstract: CONSERVATION OPENER Abstract of the Disclosure A single disk opener blade is supported for rotation about a horizontal axis offset approximately seven degrees from the transverse direction.  A seed tube extends closely adjacent the disk blade forwardly of the rotational axis generally in the shadow of the leading edge of the blade.  The tube is angled around the disk blade hub to provide a narrow profile and to reduce the vertical velocity of the material deposited in the furrow.  A furrow-firming and blade-scraping extension is connected to the lower end of the tube and extends rearwardly to a location behind the axis.  The side of the firming extension is located transversely beyond the shadow of the disk blade to help form one side of the seed trench and to permit the seed to settle in the trench.  Depth control structure includes a wheel support arm fixed to one end of the disk blade spindle and a quadrant fixed to the opposite end of the spindle for selectively adjusting the arm.  A depth control wheel is mounted on the arm about an axis offset from the axis of the disk blade for rotation against the leading side of the blade to clean the blade, hold down trash and dirt, and provide positive depth control.

Title: Steam generator
Inventor: MOELLENHOFF HORST
IPC: F22B31/00
Filed: 1987-12-22
Granted: 1993-03-23
Abstract: ABSTRACT A steam generator using a fluidized bed furnace and comprising a gas-tight combustion chamber, with a fluidized bed in its lower region and defining a space above the fluidized bed containing a plurality of heated surfaces.  A plurality of primary separators communicate with the space within the combustion chamber for removing solids from flue gases exiting the combustion chamber.  A solids return system communicates with the separators for returning solids to the fluidized bed and a pressurized containment vessel is provided for the combustion chamber, primary separators and solids return system.  Thus, in the steam generator of this invention, all the systems required for its operation can be accomodated within a common pressure vessel.  The steam generator is so constructed that it supplies the steam needed to drive a conventional steam turbine.  By using pressure within the combustion chamber the performance of the steam generator is considerably enhanced.  The temperature of the flue gases is so reduced that the gases can be utilized at the existing pressure in a gas turbine to drive the air compressor.  When this is done, there is no need for hot-gas filters and systems to remove the waste heat.  For this reason, the steam generator can be used both for new plants and to replace an existing boiler in the water-circulating stage of an existing steam-powered generating plant.

Abstract: Abstract of the Disclosure The brine tube of an ice thermal storage tank has a surface enhancement which provides nucleation sites for ice formation, and reduces the need to super chill the water.  The tubing enhancement comprises a multiplicity of solid mineral particles distributed evenly over its surface.  The particles have jagged, multi-faceted surfaces which adsorb air.  When the brine in the tube cools the water to the freezing point, the adsorbed air coalesces into air bubbles that serve as nucleation sites.
