A filter for separating contaminants from a gas stream, including (a) a housing having a housing body and a housing head, the housing head having an inlet for the gas stream to be purified, an outlet and a first sealing surface, and (b) a filter element accommodated in the housing, having an element head and an element body having a central element axis and an element interior. The element head has a second sealing surface which cooperates with the first sealing surface. A curved inlet manifold is formed between the inlet and the element interior. The inlet manifold is embodied partly in the housing head and partly in the element head such that the first and second sealing surfaces contact in a sealing plane at a 90° to 60° angle to the element axis. A radially arranged seal is provided on the sealing plane, forming one of the sealing surfaces.

A personal computer for a handicapped person includes an input panel that is subdivided into a group of fields, with one of the fields designated as a central field for the group. Each field is, in turn, subdivided into nine elements (spaces) comprised of a neutral central element surrounded by eight output elements. Each of those eight output elements has an output character representing a respective output signal. A mark (cursor) is moved across the panel by a control stick that is manipulated by a user. The cursor is always initially located at the center element of the central field. In order to move the cursor to a desired output element, the user: (a) identifies the field in which the desired output character is located, (b) moves the cursor in a first direction to the central element of that identified field, and (c) moves the cursor by one space directly to the desired output element in a second direction oriented either orthogonally or diagonally to the first direction.

The invention described is a system for seismic isolation or vibration of structures which is simple, relatively inexpensive and readily used for smaller structures. It involves use of bearings comprising a ball (10) and ball seats (12, 18) interposed between the structure and its foundation. Either the ball itself (24) or the seat surface (15) on which it rolls is compressible, the resistance to that compression providing a frictional braking force resisting rolling of the ball. This serves to dampen relative movement between the structure and its foundation. There are described several alternative constructions of the friction ball which is the preferred central element in the bearing device. There may be a plurality of balls (44, 47) in each combination of balls and seats.

Hairdressing tongs have a pair of arms extending from handles. Each arm has a heating pad affixed thereto. The handles have opposed openings. A central element is positioned between the handles and fitted within the openings such that the central element is slidable toward the handles. The central element has guide openings. Springs are positioned in the guide openings for biasing apart the handles. The springs enable hand pressure to move the handles and arms together from a completely open position to a completely closed position and, in absence of the hand pressure, to maintain the handles and arms in relatively parallel configuration, biased against stops of the central element.

A method of manufacturing a cellular reflectarray antenna arranged in an m by n matrix of radiating elements for communication with a satellite includes steps of determining a delay φm,n for each of said m by n matrix of elements of said cellular reflectarray antenna using sub-steps of: determining the longitude and latitude of operation, determining elevation and azimuth angles of the reflectarray with respect to the satellite and converting theta₀ (θ₀) and phi₀ (φ₀), determining Δβ_m,n, the pointing vector correction, for a given inter-element spacing and wavelength, determining Δφ_m,n, the spherical wave front correction factor, for a given radius from the central element and/or from measured data from the feed horn; and, determining a delay φm,n for each of said m by n matrix of elements as a function of Δβ_m,n and Δφ_m,n..

A metrology target mask for determining proper lithographic exposure dose and/or focus in a pattern formed in a layer on a semiconductor substrate by lithographic processing. The target mask comprises a mask substrate and a first, dose and focus sensitive mask portion on the mask substrate having a first array of elements comprising a plurality of spaced, substantially parallel elements having essentially the same length and width. Ends of the individual elements are aligned to form first and second opposing array edges, with the lengths of and spaces between the elements being sensitive to both dose and focus of an energy beam when lithographically printed in a layer on a semiconductor substrate. The target mask also includes a second, dose sensitive mask portion on the mask substrate having a second array of elements comprising a central element having a length and a width, and a plurality of spaced, substantially parallel outer elements having a length and a width. The width of the outer elements is less than the width of the central element, with edges of outer elements on each side of and farthest from the central element forming opposing array edges. The pitch of the outer elements is selected such that the outer elements are not resolvable after lithographic printing in a layer on a semiconductor substrate. The resulting printed second target portion width is sensitive to dose but not focus of the energy beam. Dose and/or focus of the energy beam during lithographic processing of the layer may be determined after projecting an energy beam through the mask and lithographically printing the mask portions in a layer on a semiconductor substrate and determining the widths of the first and second target portions in the layer by measuring distance between opposing array edges in each of the first and second portions.

A precursor yarn or thread is made by passing a central element, e.g., a filament, a tow, or a flat member, through a bath of a binder, such as a low-temperature hot-melt adhesive, and aqueous urethane, or an acrylic material, with which is mixed a quantity of hard-shelled microspheres which expand when heated to a higher temperature. This is then covered by a sheath, e.g, of PVC, polyurethane, polyester, acrylic resin, polycarbonate, polypropylene, or polyethylene in a second bath. When this product is heated to a transition temperature which is characteristic of the microspheres chosen, the microspheres expand, swelling the sheath. Such a precursor could be woven into a fabric and then heated, so that as the yarn expands the fabric mesh becomes tighter, reducing its porosity. This would be useful as a yarn in making papermaker's felts. Heat-expansible threads made similarly would be useful in manufacture of shoes, sails, tents, clothing and other items where porosity is undesirable; that is, the product could be sewn together using the thread of the invention and then heat-treated, causing the thread to expand, sealing the holes made in sewing. Such threads would also be useful for decorative purposes, e.g., as embroidery yarns, and likely for other purposes. The yarns of the invention can also be disposed in a desired position and infused with a hardening resin while heat is applied to cause the microspheres to expand, forming a lightweight and stiff composite structure.

A method of adaptive pixel correction of a multi-color matrix from a sensor includes collecting pixel values, generating plural vectors, normalizing values and determining an estimated value. The collecting pixel values collects values of a two-dimensional multi-pixel kernel around a particular pixel from the multi-color matrix. The generating plural vectors generates vectors from the kernel where each vector has the particular pixel as a central element. The normalizing values normalizes values for nearest neighbor elements to the central element for each vector. The determining an estimated value determines the value based on the normalized values.
