Abstract: Isotropic magnetic alloy powder having an intrinsic magnetic induction of at least two third of its magnetic remanence and method for making same are provided. The powder is made from an alloy having a composition comprising, by weight percentage, approximately 15 to 35 percent of one or more rare earth metals, approximately 0.5 to 4.5 percent of boron, and approximately 0 to 20 percent of cobalt, balanced with iron. The alloy powder is made by a process wherein an amount of the alloy is melt and spun in an inert environment, preferably at a distance between an orifice and a wheel being less than one and one half inches, into ribbons, followed by crushing the ribbons into powder and annealing the powder.

Abstract: An interconnect system is provided. The interconnect system includes a silicon substrate and a first dielectric layer formed upon the silicon substrate. The interconnect system also includes a first level of at least two electrically conductive lines formed upon the first dielectric layer. The interconnect system further includes a region of low dielectric constant material formed between the at least two electrically conductive lines. The interconnect system also includes a first hard mask formed upon the polymer region.

Abstract: A shock tool includes a first tubular member, a second tubular member and a third tubular member. The first tubular member has an interior bore that extends between a first end and a second end. The second tubular member has an interior bore that extends between a first end and an attachment end. The second tubular member is rotatably supported by both radial and thrust bearings within the interior bore of the first tubular member with the attachment end protruding from the second end of the first tubular member. The third tubular member has an interior bore that extends between a connection end and a second end. The second end of the third tubular member being telescopically received within the interior bore at the first end of the second tubular member with the connection end protruding. The third tubular member is capable of limited reciprocal movement relative to the second tubular member. Shock absorbing medium is disposed between the third tubular member and the second tubular member.

Abstract: A shoe rack includes a stand supporting at least one shoe mount over a removable bin. Each shoe mount may be connected to the stand by a strut so that the sole of a shoe placed around a shoe mount is presented in a position convenient for removal of cleats. A shoe mount is shaped so as to prevent substantial rotation of the shoe in reaction to the turning of a cleat. Removed cleats and debris collected in the bin may be disposed by removal and emptying of the bin. Several shoe mounts may be used to accommodate shoes of different sizes.

Abstract: The present invention is directed toward a concrete masonry block used to construct masonry walls in a building. The concrete masonry block has an external plate or plates that are anchored through the concrete masonry block. The external plate or plates many cover a small or substantial portion of the external surfaces of the concrete masonry block. The casting machine that casts the concrete masonry block receives the external plate or plates and anchors into the mold prior to casting the concrete masonry block. During casting, concrete is formed around the anchors, but inside the external plates. Thereafter, walls are built using some of the cured concrete masonry blocks with external plates at preselected locations to anchor things to the wall by attaching to the plates. Such masonry blocks are particularly useful in constructing buildings that must be structurally strong, functional, and easy to maintain.

Abstract: Low density fibrous materials such as carbon fibers are readily added and dispersed into a liquid such as a fracturing fluid liquid by injecting the fibers into the liquid adjacent to the liquid-gas interface at the surface of the liquid. The fibrous materials are preferably compacted to a uniform bulk density in a container in which all the gas in the compacted fibers has been displaced by a liquid. A crimped cartridge having a piston to discharge the compacted fibrous material into the liquid is preferred.

Abstract: A biarch consists of two coplanar arches, curved in the same direction and radially spaced with cross ties having shear rigidity in planes perpendicular to the cross section areal center curve of the arch pair. End ties resist relative tangential arch displacements. Biarch framing members are strong, stiff, durable and economical structural members for framing aesthetically pleasing, clear span arched structures capable of withstanding hurricane winds and mountain snows. The most efficient materials for constructing biarch framing members are hardwoods, aluminum and steel. Biarch frames spanning up to fifty feet can be assembled or disassembled by one or two persons using common hand tools.

Abstract: The invention described herein is a method and apparatus for vein location. The apparatus includes a vein locating device composed an inflatable bladder attached between two covers and including a holding straps for attaching the device to a limb of a human patient. The method described herein sets for the steps of placing the apparatus on the limb of a human patient and inflating the device so as to constrict veins in a desired area so as to permit the location of a particular vein or veins.

Abstract: A method and apparatus for providing a dynamic fine track seeking operation that adaptively fine tunes the entrance criteria used to determine when the head is on track for the specific disc drive under actual operating conditions. The method and apparatus includes adaptively modifying entrance criteria individually for each head in a disc drive according to actual operating conditions with the use of stored entrance criteria for each head, an extra track proximity threshold and a successful entrance counter.

Abstract: A line feed ratchet arrangement is disclosed which allows selectability between two different line feeds such as the 5 1/3 lines per inch and six lines per inch and utilizes a drive pawl arrangement having two pawls driven identically. The drive ratchets are selectively engaged by coaxial shifting of a drive member in response to operator movement of a selector knob or similar control.

Abstract: A typewriter-printer includes a single element printing mechanism which is pivotable about the center line of the curved platen to an optimum print line viewing position. Printing can thus take place, for example, along a print line located below the center line of the curved platen or, in the alternative, above the platen center line in accordance with operator adjustment of the printing mechanism. The printing mechanism is mounted for printing motion and is further mounted for escapement motion with respect to the stationary platen.

Abstract: This invention relates to bridge sections and is particularly concerned w bridge sections of the type which incorporates tensioned cables to reinforce the structure of the bridge sections. The cables are tensioned to provide a bowstring truss section in the completed bridge.

Abstract: Disclosed is a device for facilitating the calibration and setting of the inclination angle of a luminaire by sighting from the rear of the luminaire to a set of points such as the opposite curb of a roadway. The device may be placed on or permanently secured to the luminaire and is settable according to a derived calibrated table, either empirically derived or calculated, based on such factors as pole height, distance of pole from highway, width of the roadway, and the like.

Abstract: An attack warning system for alerting ground troops or ships to the possiity of attack by enemy aircraft. The system establishes a detection shell at a range of 3 miles covering 360.degree. in azimuth and 60.degree. in elevation. The bearing measurement is obtained by a combination of antenna pattern shape and P-N Code modulation. A pair of oppositely facing receiving antennas and a pair of oppositely facing transmitting antennas located orthogonally with respect to the receiving antennas provide the 360.degree. coverage. The azimuth pattern of each antenna covers 180.degree.. The system provides target bearing information by applying different codes to each of the two opposed transmit antennas and multiply decoding the received signals.
