Patent CA-2221920-C (CA)
Inventor: INOKUCHI KENJI
IPC: C10G1/08

Abstract: The invention relates to an iron sulfide characterized in that it comprises from 85 to 100 wt% FeS2, from 5 to 0 wt% Fe1-X S (X:0 to 0.2), from 5 to 0 wt% Fe3O4 and from 10 to 0 wt% FeSO4 as determined by X-ray diffractometry, and that the secondary particles thereof each made up of primary particles having a particle diameter of from 10 to 400 nm have a 5O% volume-cumulative particle diameter of from 20 to 300 .mu.. The invention also relates to a process for producing an iron sulfide characterized by comprising the steps of introducing (a) an iron sulfate comprising, as a main component, ferrous sulfate monohydrate having a d50 of from 20 to 300 .mu. and (b) not less than stoichiometric amount of at least one sulfur compound selected from elemental sulfur in a powder, melt or vapor state and hydrogen sulfide into the fluidized bed of a fluidized burning furnace and then fluidizing, burning, and reacting the ingredients at a temperature of from 350 to 630.degree.C, excluding 630.degree.C, a superficial velocity of 0.1 m/sec or higher, and a pressure of 1 atm or higher using air as a fluidizing gas for utilizing sulfur combustion to supply heat necessary for maintaining the reaction temperature. The iron disulfide yielded has a high purity and is in a granular form having excellent handleability. It can be reduced into submicron particles by a simple disaggregating operation. The fine particles, when used, e.g., as a -51- catalyst for coal liquefaction, exhibit high activity in hydrogenation reaction to enable high-yield oil production from coal. The acid gas generating in the production is recovered as sulfuric acid and elemental sulfur respectively through oxidation and reduction. The sulfuric acid can be used for producing iron sulfate together with scrap iron or the like. Thus, a non-polluting resource-saving production process is possible in which by-products are reused as starting materials. -52-

Title: Vanne hydraulique permettant le maintien de la regulation dans des conditions de perte de fluide
Inventor: WILKE RAUD A
IPC: F15B11/04

Granted: 2001-10-30
Abstract: Vanne hydraulique de régulation qui empêche le mouvement incontrôlé d'une charge en cas de perte de fluide, tel que l'éclatement d'un tuyau, et qui permet en outre à un opérateur de déplacer la charge d'une manière contrôlée en dépit de ladite perte de fluide. Ladite vanne de régulation est située entre un distributeur à tiroir principal classique et un actionneur hydraulique à piston/cylindre qui actionne la charge. Ladite vanne de régulation possède un tiroir qui coulisse dans un alésage en effectuant un mouvement de va-et-vient. Des rainures et des îlots sur le tiroir se combinent à des passages dans le corps de vanne de régulation pour fournir des voies de fluides alternatives entre une pompe et l'actionneur et entre l'actionneur et un réservoir. Du fluide peut s'écouler d'une chambre régulée de l'actionneur uniquement lorsque le tiroir est dans une position qui permet une voie de fluide. Un passage à l'intérieur du tiroir fournit une communication fluidique entre un flux de fluide d'entrée et une chambre à une extrémité du tiroir. Un second passage à l'intérieur du tiroir fournit une communication fluidique entre une chambre d'actionneur et une chambre à l'autre extrémité du tiroir. La position du tiroir est déterminée par l'équilibrage des pressions des chambres terminales opposées qui est sous le contrôle de l'opérateur.

Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by a chamber that communicates with the second orifice through a gap between the first and second orifices. A spout delivers casing glass from a second source through a tube to the chamber in such a way that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. Rate of glass flow through the second or casing glass source is measured and compared with one or more preset limits. Rate of casing glass flow from the second source to the chamber surrounding the orifices is adjusted when rate of flow through the second source departs from the preset limit. In this way, a desired ratio of casing glass to core glass, and consequently the desired thickness of the casing glass layer, is automatically maintained

Title: Tubular blanket and printing machine using tubular blanket
Inventor: HARADA TAKAO
IPC: B41N10/02
Filed: 1998-04-27
Granted: 2002-02-12
Abstract: The present invention relates to a tubular blanket which comprises a main blanket section having at least a portion coming into contact with a printing-made web and a remaining blanket section other than the main blanket section. The remaining blanket section has a thickness thinner than the thickness of the main blanket section. Thus, even if inks or paper particles are attached to a web absent area on a circumferential surface of the tubular blanket, it is possible to eliminate the influence from the attachment of inks or paper particles, and to make the web cut-off hard to occur, so that the interference with the use of the tubular blanket is preventable, thereby enhancing the economy and the working efficiency.

Abstract: A method for analyzing blood enables one to isolate, detect, enumerate and confirm under magnification the presence or absence of target cancer cells and/or hematologic progenitor cells which are known to circulate in blood. The analysis is performed in a sample of centrifuged anticoagulated whole blood. The analysis involves both morphometric and epitopic examination of the blood sample while the blood sample is disposed in a centrifuged blood sampling tube. The epitopic analysis of the presence or absence of cancer cells relies on the detection of epitopes which are known to present only on cancer cells; and the epitopic analysis of the presence or absence of hematologic progenitor cells relies on the detection of epitopes which are known to present only on hematologic progenitor cells. The targeted epitopes on the target cell types are epitopes which are also known to be absent on normal circulating blood cells; and the target cancer cell epitopes are epitopes which are known to be absent on target hematologic progenitor cells. Fluorophors with distinct emissions are coupled with antibodies which are directed against the targeted epitopes. The morphometric analysis is performed by staining the cells in the blood sample with an intracellular stain such as acridine orange which highlights the intracellular cell structure. Both the morphometric and epitopic analyses are preferably performed at or near the platelet layer of the expanded buffy coat in the centrifuged blood sample. The morphometric analysis and/or the epitopic analysis may be performed under magnification both visually and/or photometrically.

Abstract: A combined cycle power plant mixes steam heated to a high temperature by cooling a high temperature cooled part of a gas turbine. Other steam favorably guarantees the safety of the alternating current apparatus, so that it is operated stably over a long period of time. The combined cycle power plant has a mixing tube that mixes exit steam from a steam cooling system and a bypass steam. The exit steam from the steam cooling system that has been heated by cooling the high temperature cooled part of this gas turbine and the bypass steam that bypasses this high temperature cooled part in order to control flow volume and temperature of the steam introduced into the high temperature cooled part are introduced into the mixing tube and mixed. Thus a mixed superheated steam having uniform pressure and temperature is formed, with no deleterious effect on any downstream equipment.
