Title: Method of producing gas from fluid containing beds
Inventor: BELONENKO VLADIMIR NIKOLAEVICH
IPC: E21B28/00
Filed: 1993-12-27
Abstract: A method of producing gas from fluid containing beds having at least one gas trap, includes influencing the bed by means of elastic vibrations generated directly in the bed and/or in a medium contacting the bed, and removal of gas from the trap, a source oscillation frequency being varied during the influence from a minimum value to a maximum one and vice versa within the frequency range from 0.1 to 350 Hz, preferably from 1 to 30 Hz.    The frequency variation is effected in a monotonous way, including the influence in accordance with the harmonic law, and/or in a discrete  way. The  discrete  variation  of the frequency is accompanied by increasing the oscillation amplitude. Additionally, a pressure is reduced in the bed or a part thereof. The additional oscillation sources are used. Periodical oscillations are accompanied by influencing by means of pulses, batches of pulses and/or wave trains.    The bed fluid is pumped out, transported to the surface, the heat thereof is utilized, and the fluid is repumped to the bed at a simultaneous influence by means of elastic vibrations.    To transmit the oscillating influence to the bed, a wavequide, provided with a concentrator, is used.

Title: Process for recovering organic sulfur compounds from fuel oil and equipment therefor
Inventor: FUNAKOSHI IZUMI
IPC: C10G21/28
Filed: 1995-10-03
Abstract: The present invention provides a process and equipment for efficiently and economically recovering organic sulfur compounds in a fuel oil while maintaining the original chemical structures thereof.          The fuel oil is admixed with a solvent low in solubility therein of hydrocarbons and high in solubility therein of organic sulfur compounds to effect migration of the organic sulfur compounds in the fuel oil into the solvent by making much of the nucleophilic properties of a lone pair of electrons on a bivalent sulfur atom of a sulfur-containing functional group, followed by fuel oil-solvent separation by settling out or with a centrifugal force.  Alternatively, a solvent having a boiling point not exceeding the boiling point of the fuel oil is added to the fuel oil, and the solvent and the fuel oil are then agitated and mixed together at a temperature of at most the boiling point of the solvent to effect migration of the organic sulfur compounds in the fuel oil into the solvent while lowering the viscosity of the fuel oil, followed by cooling of the fuel oil and the solvent to a temperature not exceeding room temperature and subsequent fuel oil-solvent separation by settling out or with a centrifugal force.  Subsequently, the separated solvent is distilled to recover the organic sulfur compounds.

Patent CA-2172274-A1 (CA)
Inventor: KRALL JACK
IPC: B22F1/10
Filed: 1994-07-15
Abstract: A method for forming a sintered hard metal composite is provided in which unsintered nodules of a pre-blended hard metal powder of a first grade are uniformly dispersed into unsintered nodules of a pre-blended hard metal composite of a second grade. The pre-blended hard metal powders form a composite powder blend which is subsequently pressed and sintered to form the dispersion alloyed hard metal composite. A sufficient amount of pressing lubricant is provided to one of the pre-blended hard metal powders so that each of the hard metal powders shrinks at approximately the same rate relative to the application of pressure during the compacting process. The pressing lubricant is added to that hard metal powder which shrinks more during sintering. By providing uniform shrinkage of the constituent powder grades, migration of the binder from one constituent grade to the other constituent grade is minimized, thereby allowing the composite powder blend to achieve superior properties because each of the constituent grades maintains its own integrity. In addition, the uniform shrinkage of the constituent powders prevents irregular surface conditions of the "as sintered" surface.

Abstract: Disclosed is a method for making dry coffee aroma gas with improved aroma characteristics, A stream of moisture-containing coffee aroma gas is passed through and allowed to exit a desiccant bed of calcium sulfate granules, wherein said granules initially contain less than about 0.5 % adsorbed moisture by dry weight of said granules. The stream of moisture-containing coffee aroma gas is discontinued after the adsorbed moisture content of the calcium sulfate granules increases from less than about 0.5 % to at least about 4.3 % by dry weight of said granules, but before the moisture content of the stream of desiccant-treated coffee aroma gas exiting the desiccant bed exceeds about 1000 ppm. All of the desiccant-treated coffee aroma gas which exits the desiccant bed is collected and combined until the stream of moisture-containing coffee aroma gas is dicontinued. The desiccant-treated coffee aroma gas contains between about 10 and about 200 ppm of moisture and does not exhibit an unbalanced and excessively musty aroma. The dessicant-treated coffee aroma gas can be used to aromatize food substrates, e.g., instant coffee.

Abstract: A method and system for formatting numerical information. An object-based operating system provides various number formatting services. Some objects scan text and convert the text to numerical information, and convert non-text numerical information to text, and convert between different numerical formats and languages. The system provides a common ground from which application programs can speak a seemingly common numerical language without specifying the details of converting numerical information between systems of representation. The present system relieves application developers of the burden of handling details of numerical information, and provides ease of information transfer between monetary systems and cultures having differing languages. The system also provides for conversion between number formats to allow for easier processing and/or comprehension of the numerical information, and normalization and alignment of any textual representation of numeric information.

Abstract: Multiple hair removal system includes an adhesive layer (52), a structural layer (54) disposed adjacent the adhesive layer (52), and a conductive material (56). The conductive material (56) functions to provide power from a power source (70) to hairs to be treated that extend up through the adhesive layer (52) and contact the conductive material (56). A method of removing multiple hairs and inhibiting future hair growth includes the steps of applying a conductive solution to the hair, pressing on an adhesive layer (52), applying power for a period of time sufficient to destroy the matrix area of the hair, and allowing the treated hair to either be removed immediately or to stay in the skin for a period of time sufficient for the chemical reaction induced at the matrix area to continue long enough to destroy the matrix area and prevent re-growth of the hair.
