  • Patent number: 5827797
    Abstract: A process for producing fibers of refractory material. In one embodiment, a dispersion of particles of refractory material is prepared first. The dispersion then is mixed with a carrier solution of a salt of cellulose xanthate to form a spin mix. Using general wet spinning techniques, a filament of regenerated cellulose is formed from the spin mix. The filament has the particles dispersed therein. At this point, the filament can be utilized as a mixture of cellulose and refractory material, or it can be heat treated. If heated, the filament is raised to sufficient temperatures and over sufficient durations to remove substantially all of the regenerated cellulose and to sinter the particles of refractory material to form a filament.

  • Patent number: 5815245
    Abstract: A small field scanning photolithography system uses opposing motion of a reticle and a blank to compensate for image reversal by a projection system such as a conventional Wynne-Dyson optical system which forms a reverted image on a blank. The reticle has a reverted pattern. During scanning, the reticle moves along a reverted axis in a direction opposite the direction in which the blank moves. The opposing motions can either expose a stripe on the blank or index the reticle and blank for exposure of a next stripe. In one embodiment of the invention, the reticle and blank are on independently movable precision air bearing stages. Typically, the blank and reticle move together perpendicular the reverted axis and in opposite direction along the reverted axis. The stages can move the reticle and blank different amounts to correct for shrinkage and temperature changes which cause the size of the reticle and blank to differ.

  • Patent number: 5804994
    Abstract: A comparator with hysteresis which has a bias current circuit, a differential input stage, and an output stage is disclosed. The differential input stage uses a parallel transistor and an enabling transistor connected in parallel to one of the differential pair transistors to create hysteresis. The parallel transistor and enabling transistor are used to generated an effective offset voltage which must be overcome for the comparator to switch states.

  • Patent number: 5792775
    Abstract: The present invention provides a family of tropane analogs. More particularly, the present invention provides a family of 4' and 4',4"-substituted-3.alpha.-(diphenylmethoxy)tropane analogs having the formula ##STR1## in which R is a functional group including, but not limited to, hydrogen, alkyl, alkoxy, arylalkyl, aryloxyalkyl, cinnamyl and acyl; and R.sup.1 and R.sup.2 are independently selected and are functional groups including, but not limited to, hydrogen, alkyl, alkoxy, hydroxy, halogen, cyano, amino and nitro. The benztropine analogs of the present invention have a high affinity for the dopamine transporter and inhibit dopamine uptake, but they do not exhibit a cocaine-like behavioral profile. Moreover, the present invention provides methods of using such benztropine analogs to treat cocaine abuse, to image dopamine transporter/cocaine binding sites, and to diagnose and/or monitor neurodegenerative disorders (e.g., Parkinson's disease).

  • Patent number: 5781346
    Abstract: Magnification correction for small field scanning of large blanks is provided by adding magnification adjusting elements (lenses) to a double pass Wynne-Dyson lens or other type of one-to-one projection lens. The magnification adjusting optical elements includes two pairs of low power lenses, one associated with each of the input and output prisms of a Wynne-Dyson lens. Movement of the magnification adjusting optics provides positive or negative magnification as needed to correct for any expansion or compaction of the blank relative to the reticle (mask) and hence maintain alignment. Further magnification correction is provided by a small velocity relative movement between the reticle and the blank by means of a secondary stage in the scan direction. This corrects for any alignment error in the scan direction and may be used independently of the optical correction technique with any type of projection lens.

  • Patent number: 5779276
    Abstract: Single or multi-piece, pipe joint seal elements have at least one slidable interface that contacts a sealing surface of an end ring attached to a cementitious pipe liner. The slidable interface allows for slippage between seal pieces and/or seal piece-end ring surfaces during pipe joint assembly and disassembly. The end rings help distribute and minimize rotational and other stresses exerted upon the liner end surfaces and seal pieces. Such end ring surfaces further provide a quality surface for the seal element to effect a seal. The slidable interface seal is especially useful for joining brittle-lined pipe sections handling harsh fluids such as geothermal brine, etc.

  • Patent number: 5756090
    Abstract: Methods and compositions are disclosed for producing air-activated, i.e., oxygen (O.sub.2) activated, disinfectant-sterilent solutions. Solutions containing a haloperoxidase (i.e., a halide:hydrogen peroxide (H.sub.2 O.sub.2) oxidoreductase, such as myeloperoxidase, eosinophil peroxidase or lactoperoxidase) plus a halide or combination of halides (i.e., chloride, bromide and/or iodide), an oxidase (i.e., a substrate: O.sub.2 oxidoreductase) capable of generating H.sub.2 O.sub.2, and a substrate specific for that oxidase, are separately prepared under aerobic conditions, but all of the component solutions are made anaerobic prior to final combination and mixing. The anaerobic formulations are dispensed into containers capable of maintaining the anaerobic condition (e.g., pressurized canisters). Dispensing the solution at the time of use exposes the formulation to air (i.e., O.sub.2) which activates its disinfectant-sterilent properties. O.sub.2 is the rate limiting component for oxidase generation of H.sub.

  • Patent number: 5757474
    Abstract: A method and apparatus for measuring characteristics of a piece of material, typically semiconductor materials including photovoltaic devices. The characteristics may include dislocation defect density, grain boundaries, reflectance, external LBIC, internal LBIC, and minority carrier diffusion length. The apparatus includes a light source, an integrating sphere, and a detector communicating with a computer. The measurement or calculation of the characteristics is calibrated to provide accurate, absolute values. The calibration is performed by substituting a standard sample for the piece of material, the sample having a known quantity of one or more of the relevant characteristics. The quantity measured by the system of the relevant characteristic is compared to the known quantity and a calibration constant is created thereby.

  • Patent number: 5757469
    Abstract: A small field scanning photolithography system has a double pass Wynne-Dyson optical system which provides an erect, non-reverted, unmagnified image. An optical path through the system passes from an object, reflects off an input reflector, passes through a first quadrant of a lens, reflects off a concave mirror, passes through a second quadrant of the lens into folding optics where an intermediate image forms, passes from the folding optics through a third quadrant of the lens, reflects off the concave mirror a second time, passes through a fourth quadrant of the lens, and finally reflects off an output reflector to a plane where a final image forms. Typically, the input and output reflectors and the folding optics are prisms. A field stop may be provided in the folding optics where the intermediate image forms. Magnification adjusting optics can be added to the input and output prisms or to the folding optics.

  • Patent number: 5750400
    Abstract: This invention is directed to three coding sequences of the BRCA1 gene. The three coding sequences, BRCA1.sup.(omi1), BRCA1.sup.(omi2) and BRCA1.sup.(omi3) as well as their frequencies of occurrence are provided together with the protein sequences they code for. Another aspect of this invention is a method of determining the consensus sequence for any gene. Another aspect of the invention is a method of identifying an individual having an increased genetic susceptibility to breast or ovarian cancer because they have inherited a causative mutation in their BRCA1 gene. This invention is also related to a method of performing gene therapy with any of the isolated BRCA1 coding sequences.
