    Abstract: A structured packing formed of a plurality of corrugated, rectangular sheets and a method relating to the use thereof. End regions of the corrugations are provided with straight, parallel corrugations extending inwardly from opposed edges of the sheets and a right angles thereto to reduce pressure drop at the interfaces between packing layers and thereby increase hydraulic capacity. Contact is promoted between descending liquid and ascending vapor phases within a main region of the corrugations that have straight, parallel sections of the corrugations oriented at an acute angle to the opposed edges. Transition regions having arcuate sections of the corrugations connect corrugations within the main and end regions to reduce internal pressure drop within the structured packing and thereby further reduce pressure drop at the interfaces and further increase the hydraulic capacity.

    Abstract: In the method of making a thin-film magnetic head in accordance with the present invention, an alignment mark is electrically connected to a multilayer film which will later become a TMR film. Therefore, when the alignment mark is irradiated with a position correcting electron beam in order to correct a drawing position in the subsequent step of electron beam lithography, electric charges of the electron beam flow into the multilayer film without staying in the alignment mark. As a consequence, the position correcting electron beam does not lose its straightforwardness, whereby the drawing position in electron beam lithography can be corrected accurately.

  • Patent number: 5747140
    Abstract: A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body.

    Abstract: The structure and process for making a metallic panel structure from a plurality of core panels each comprised of a pair of sheets of superplastic material welded together along a plurality of weld lines. The core panels are joined together, with the weld lines of one core panel positioned normal to the weld lines of the adjacent core panel. The resulting assembly is placed in a die. The die is heated to superplastic forming temperature, and gas pressure is applied to the spaces between the sheets of the respective core panels, causing superplastic forming and expansion of the sheets of each core panel to form a series of bulges between weld lines of one core panel, and a series of similar bulges between weld lines of the adjacent core panel, the bulges expanding inwardly toward each other. The two series of bulges are orthogonally disposed, the bulges from the two core panels contacting and forming around each other.

  • Patent number: 5162143
    Abstract: A uniformly flexible core, and method for manufacturing the same, for use between the face plates of a sandwich structure. The core is made of a plurality of thin corrugated strips, the corrugations being defined by a plurality of peaks and valleys connected to one another by a plurality of diagonal risers. The corrugated strips are orthogonally criss-crossed to form the core. The core is particualrly suitable for use with high accuracy spherically curved sandwich structures because undesirable stresses in the curved face plates are minimized due to the uniform flexibility characteristics of the core in both the X and Y directions. The core is self-venting because of the open geometry of the corrugations. The core can be made from any suitable composite, metal, or polymer. Thermal expansion problems in sandwich structures may be minimized by making the core from the same composite materials that are selected in the manufacture of the curved face plates because of their low coefficients of thermal expansion.

  • Patent number: 5128195
    Abstract: A woven core structure (2) includes a first and second face sheets (4, 6) with inner surfaces (16, 18) facing one another. First and second sets of corrugated ribbons (8, 10) are positioned between the face sheets. The ribbons have nodes (12, 14) which are secured to the inner surfaces of the face sheets. The first set of ribbons extend transversely to, and preferably perpendicular to the second set of ribbons. The first and second sets of ribbons are woven such that the nodes of the first set of ribbons are spaced apart from and generally opposite the nodes of the second set of ribbons. This arrangement permits an increase in the node contact area (26) between the nodes and the face sheets to enhance the bond strength between the ribbons and the face sheets and to increase the skin deformation strength of the structure. The angle between the ribbons and the face sheets can be adjusted to optimize shear strength versus tension/compression strength.

  • Patent number: 5051294
    Abstract: A substrate for a catalytic converter is formed of steel sheets embossed with corrugations in a chevron pattern such that the metal buckles at vertices of adjoining corrugations to form projections extending out of the plane of the sheet. The sheets are stacked with the projections registered to form weld points and capacitive discharge welding secures the sheets together. The substrate is formed in two halves which are clamped together and then secured by end rings.

    Abstract: A heat transfer element for cross flow heat exchanger consists of ceramic corrugated and planar plates. A plurality of the heat transfer elements are stacked up in such a manner that the direction of corrugation in adjacent elements intersects at right angles to form a heat transfer block for cross flow heat exchanger. Concave portions of corrugation, which confront soot-blowing flow for removing soot deposited onto the heat transfer surfaces of heat transfer block, are filled with ceramic solids. Also concave portions of corrugation corresponding to the corners, which abut the packings attached when the heat transfer block is installed on a casing, are filled with ceramic solids.

    Abstract: A gas/liquid contact apparatus which includes a plurality of packing sheets arranged in parallel, vertical, upright, face to face relationship. The packing sheets have a series of inclined corrugations formed therein. Each of the corrugations are formed so as to define an alternating series of longitudinally extending oppositely inclined surfaces which intersect and pass through a center plane of the packing sheet so as to define hills and valleys. The inclined surfaces have an amplitude relative to the center plane of the packing sheet which is opposite that of the adjacent inclined surfaces of an adjacent corrugation. The packing sheets are arranged adjacent each other such that the corrugations of adjacent packing sheets are oppositely oriented. The adjacent packing sheets are secured together where the hills of one of the packing sheets contacts the valleys of an immediately adjacent packing sheet.
