Patent EP-0495319-A2 (EP)
Inventor: CROSSLAND CLIFFORD STUART
IPC: C07B61/00
Filed: 1991-12-24
Abstract: Paraffin alkylation using solid, particulate catalyst is carried out by preparing an alkane-catalyst mixture in a wash zone, passing the alkane-catalyst mixture to a plug flow reactor where a minor amount of olefin is introduced to contact the alkane-catalyst mixture and react to form alkylate and the alkane-catalyst-alkylate mixture is passed through the reactor with a minimum of back mixing to restrict the reaction of alkylate with olefin, thus substantially preventing polymerization. The alkane-catalyst-alkylate mixture, substantially free of olefin is passed to a disengaging zone where the liquid is removed and the solid particulate catalyst is recovered and returned to the wash zone for recycle. The alkane is present in the reactor in sufficient molar excess to react substantially all of the olefin. Any unreacted isoalkane is recycled to the reactor with make-up isoalkane added to maintain the molar excess. The preferred catalyst is an acid washed silica treated with antimony pentafluoride and more preferably treated with alkane at low temperature, e.g. -30 to -160°C.

Abstract: A method of filling a honeycomb or similar multi-cell structure with a very uniform polyimide foam. A very uniform layer of finely divided polyimide foam precursor powder is formed on a mold-release coated surface within cells of a honeycomb structure on the surface. The uniform layer within the cells may be formed by forming a uniform precursor powder layer on the surface and pressing the honeycomb down through the layer. Or, precursor powder may be sifted uniformly into the cells of a honeycomb structure resting on the surface while moving the sifter across the honeycomb structure. A sheet having a mold-release surface is placed over the honeycomb. The assembly is then heated, such as in a heated platen press, to the foaming and condensation temperature of the precursor. Each cell is filled with a very uniform, controlled density, polyimide foam. The assembly may be further heated to the full cure temperature of the polyimide material.

Abstract: According to the invention, a chemically adsorbed film is formed on an apparel material which has a surface layer containing fluorocarbon groups and a stem which is chemically bonded by -Si- bonds to the material. A high performance apparel material thus can be provided which retains intrinsic properties of material such as ventilation and aesthetic appearance and is excellently durable and highly water- and oil-repelling and anti-contaminating or excellently durable and highly hydrophilic. The chemically adsorbed film has a very thin surface layer containing fluorocarbon groups, and is thus excellently water- and oil-repelling and anti-contaminating. In addition, since its stem is chemically bonded via -Si- bonds to the material, it does not separate and is excellently durable. Further, it is very thin and does not adversely effect intrinsic properties of material such as ventilation, color and aesthetic appearance.

Abstract: In systems for transmitting energy and information items with the aid of an alternating voltage, using inductive couplers, edge discontinuities in the transmitted alternating signal on the secondary side, which are due, for example, to the natural resonance of the secondary circuit, are prevented from leading to misinformation in the evaluating circuit. According to the invention, this is achieved by the balanced coupling-out of a transmitted signal at both connecting terminals (ALs and BLs) of a secondary inductance (Ls) of the inductive coupler and by further processing the signal, coupled out here, in a circuit arrangement (DV) with balance signal input and common mode suppression. <IMAGE>

Abstract: A method and apparatus for processing a document image, using a programmed general or special purpose computer, includes forming the image into image units, and at least one image unit classifier of at least one of the image units is determined, without decoding the content of the at least one of the image units. The classifier of the at least one of the image units is then compared with a classifier of another image unit. The classifier may be image unit length, width, location in the document, font, typeface, cross-section, the number of ascenders, the number of descenders, the average pixel density, the length of the top line contour, the length of the base contour, the location of image units with respect to neighboring image units, vertical position, horizontal inter-image unit spacing, and so forth. The classifier comparison can be a comparison with classifiers of image units of words in a reference table, or with classifiers of other image units in the document. Equivalent classes of image units can be generated, from which word frequency and significance can be determined. The image units can be determined by creating bounding boxes about identifiable segments or extractable units of the image, and can contain a word, a phrase, a letter, a number, a character, a glyph or the like.

Abstract: A process for producing an exhaust-gas-purifying catalyst includes the steps of immersing a porous support into a solution including a noble metal catalyst ingredient, thereby preparing a support with a noble metal catalyst ingredient loaded thereon, and thermally treating the noble-metal-catalyst-ingredient-loaded support at a temperature of 800 °C or more in non-oxidizing atmosphere. In the thermally-treating step, the noble metal catalyst ingredient is prevented from being oxidized to its oxide, and accordingly it is inhibited from migrating in vapor phase. Further, in the thermally-treating step, pores of the porous support are contracted so that they surround the noble metal catalyst ingredient closely therein. All in all, the noble metal catalyst ingredient is prevented from sintering. Thus, the resulting exhaust-gas-purifying catalyst is of superb heat-resistance, and it can be applied to elevated temperatures of 800 °C or more in fuel-lean atmosphere.

Abstract: A fixation control device is provided which controls the operation of a fixing unit (35) having a heat roller (37) and a press roller (38) between which a sheet (4A, 4B, 4C, 4D) is passed. When copies are successively made on a plurality of narrow-size sheets (4A, 4B, 4C, 4D), the temperature of the end portions of the press roller (38) rises and, therefore, the difference between the temperatures of the end portions and the central portion of the press roller (38) becomes greater. The greater temperature difference results in a diameter difference between the central portion and the end portions of the press roller (38) due to thermal expansion, thereby reducing sheet transportation ability of the heat roller (37) and press roller (38). However, the fixation control device of the present invention can compensate the reduction in the transportation ability by increasing the rotational speed of the heat roller (37) and press roller (38) when the temperature difference becomes greater.
