Granted: 1988-05-24
Abstract: "THE REMOVAL OF SULFUR COMPOUNDS FROM GASES"                 Abstract of the Disclosure For the removal of sulfur compounds, especially H2S, from gases that contain hydrocarbons, and/or CO2, the gases are scrubbed with a physical solvent, which is regenerated and reused.  To obtain sulfur free of hydro-carbons, as well as a practically sulfur-free LPG frac-tion and optionally a C5+ fraction, an oxidizing agent is added to the solvent for reacting the sulfur com-pounds to elemental sulfur, and the sulfur is separated. The concomitantly absorbed hydrocarbons and/or CO2 can then be desorbed from the separated solvent by physical regeneration and can be recovered.

Abstract: ABSTRACT OF THE DISCLOSURE A flexible sheet structure is described which comprises a base sheet having a microwave coupling layer, e.g. electrodeposited aluminum as an island covering a selected area of the sheet.  The uncoated portions will not be heated and will not be damaged by microwave energy.  The selectively located microwave coupling covered area transfers absorbed heat to a product by thermal conduction.  In one form of the invention a flexible fibrous backing sheet such as paper is bonded to the base sheet to provide dimensions stability and prevent warping, shriveling, melting of other damage during microwave heating.

Abstract: FLOTATION APPARATUS FOR CONCENTRATION OF     MINERALS FROM HIGH WATER CONTENT AQUEOUS SLURRIES                   ABSTRACT OF THE DISCLOSURE         The invention relates to the concentration and beneficiation of particulate matter by froth flotation and in particular to improvements in hydraulic-pneumatic flotation apparatus which contribute to the efficiency of operation.  Such apparatus employs a constriction plate which separates vertically arranged flotation and hy-draulic compartments.  A discharge duct may be used to extend through the hydraulic compartment and to open through the constriction plate centrally thereof.  Ori-fices in both the constriction plate are in communication with the hydraulic compartment to provide a uniform dis-persion of air bubbles in the flotation compartment.          Aerated water distribution manifolds within the hydraulic compartment and within the lower portion of the flotation compartment are provided to enter the aerated water into the flotation compartment substantially uniformly throughout a horizontal cross-section thereof.  In order to minimize the energy consumption of the apparatus and to provide for the introduction of aerated water at a re-duced flow rate  amenable to the separation of aqueous pulps having a low concentration of solid matter by volume  such as sulfides  a stream of pressurized air is passed through an eductor wherein a mixture of water and if desired  an appropriate surfactant is aspirated into the stream of flowing pressurized air.  The flowing stream of pressurized air and the aspirated water and surfactant are then passed through a venturi region  pro-ducing a highly aerated  low water volume stream of aerated water for delivery to the hydraulic compartment.

Granted: 1988-11-22
Abstract: ABSTRACT     The wind energy conversion system includes a wind machine having a propeller connected to a generator of electric power, the propeller rotating the generator in response to force of an incident wind.  The generator converts the power of the wind to electric power for use by an electric load.  Circuitry for varying the duty factor of the generator output power is connected between the generator and the load to thereby alter a loading of the generator and the propeller by the electric load.  Wind speed is sensed electro-optically to provide data of wind speed upwind of the propeller, to thereby permit tip speed ratio circuitry to operate the power control circuitry and thereby optimize the tip speed ratio by varying the loading of the propeller.  Accordingly the efficiency of the wind energy conversion system is maximized.

Abstract: A FAULT TOLERANT DUAL PORT SERIAL LINK CONTROLLER            ABSTRACT OF THE INVENTION A multiple port serial link controller printed wiring card is shown.  This printed wiring card provides at least two independent ports. These ports may be of different types such as RS-232 interface, RS-449 interface or other serial protocols such as HDLC, SDLC or BISYNC.  These printed wiring cards may be combined in a duplex fashion to form two duplex (highly reliable) port transmission circuits.  The duplex configuration requires a minimum amount of backplane wiring.  This backplane wiring is permanent and requires no manual intervention for switching between transmission and mode types.  Switching between transmission mode type and reconfiguring for the occurrence of faults may be accomplished by an automatic processor manipulation of a number of control points.

Abstract: Nitrilotriacetonitrile (NTN) is prepared by (a) reacting NH3, HCHO and HCN under strong acid conditions and (b) reacting resultant methylene-bis-iminodiacetonitrile (BIS) with HCN in liquid phase. BIS may be isolated but this not necessary. Advantages are: excellent yields of pure product, ease of operation and safety in handling large amounts of HCN, since only small amount is present at any one time, possibility of using small, continuous reaction zone and recycling, since there are no by-products. Nitrilotriacetic acid, a valuable complexing and chelating agent, is obtained by hydrolysing NTN.
