  • Patent number: 6414753
    Abstract: A monochromator is provided which reduces the amount of stray light striking the detector of the monochromator. A light source is provided which directs light to a source mirror. The source mirror reflects light from the light source through a filter and an entrance slit, and to a first monochromator mirror. The first monochromator mirror collimates the light and reflects it to a diffractive surface. The diffractive surface separates the light into its individual wavelength components. The separated light is directed from the diffractive surface to a second monochromator mirror. The second monochromator mirror directs the light to an exit slit. The present invention reduces stray light to the diffractive surface by tilting the second monochromator mirror off axis at an angle to prevent the reflected light from striking the diffractive surface or directing light out of the plane of diffraction.

  • Patent number: 6396060
    Abstract: A system for sensitively discriminating against background radiation which tends to swamp and prevent detection of radiation from a source of interest such as IR (Infra-Red) light radiation as may be found on “low observable” aircraft collision avoidance lighting, utilizes the modulation of such radiation as a mechanism for tracking the radiation and discriminating against the background radiation, for example, from other light energy sources.

  • Patent number: 6347698
    Abstract: An extruded brush plate for a conveyor is provided with slots preformed in the brush plate for attachment of supports, vibrators and peripheral walls. The brush plates are then cut to the desired length, by making only a single cut across the width of the brush plates. T-slots for attaching the vibrators and the bolt slots for attaching the peripheral walls are provided along the entire length of the brush plate such that when the brush plate is cut to any length, the vibrators may be attached where desired. Also the bolt slots will be accessible from the end of the brush plate, so that the peripheral walls may be attached. The T-slots are designed to accept T-nuts. The vibrator is attached to an interface plate. The interface plate includes threaded holes to accept a bolt. The T-nut is threaded onto the bolt and the T-nut is slipped into the T-slot so that the vibrator is attached to the brush plate.

  • Patent number: 6342705
    Abstract: In a system for locating and measuring an index mark on an edge of a wafer, a wafer to be examined is positioned and centered on a chuck in a horizontal chuck position such that an index mark is oriented within first and second index mark orientation features disposed on the chuck. The chuck is translatable, tiltable between horizontal and vertical positions, and rotatable over an angle subtended by the index mark orientation features of the chuck. A laser beam from a laser beam optical profiler is focussed on the surface of the wafer at a distance proximate the wafer edge and proximate the first index mark orientation feature of the chuck. The chuck is rotated in a direction from the first to the second index mark orientation feature whereby a reflected portion of the laser beam generates data corresponding to the angular location of index mark edges. An index mark center location is computed.

  • Patent number: 6309285
    Abstract: A magnetic wiper for removing magnetorheological fluid from a carrier surface includes a horseshoe magnet having north and south polepieces elongated in a first direction orthogonal to a second direction of magnetic flux in the magnet. The polepieces are generally parallel at their free ends in the first direction and are preferably arcuate such that the inner polepiece forms a trough for receiving magnetorheological fluid removed from the carrier surface and conveying it to an exit tube. The free ends are shaped to conform closely to the shape of the carrier surface, forming a narrow gap therebetween containing a magnetic fringing field extending beyond the free ends.

  • Patent number: 6305535
    Abstract: An improved golf bag handle assembly is provided to mount dual shoulder straps to a golf bag. The golf bag has a handle which is located on the sidewall of the bag. The central portion of the dual shoulder strap assembly is designed to be mounted to a unique handle casing which is slidably disposed on the existing golf bag handle. The strap assembly includes a mounting web connected to the central mounting element. The handle casing includes a handle portion and an attachment member or ring integral with the handle portion. The mounting web links the central mounting element to the attachment ring. The handle casing includes an internal channel adapted to accept the handle of the golf bag. The handle casing position may be adjusted such that the weight distribution between the user's shoulders may be adjusted.

  • Patent number: 6251290
    Abstract: A method for treating hydrocarbonaceous deposits to recover a petroleum-like hydrocarbon portion and a cleaned particulate substrate portion. Hydrocarbonaceous ore containing bitumen and/or kerogen is crushed or otherwise comminuted to the particle size of sand or smaller. The comminuted ore is mixed with water to form a slurry, is heated to between 60° C. and 100° C., and is blended with an oxidant in aqueous solution, preferably hydrogen peroxide. Both free interstitial hydrocarbons and those hydrocarbons bound electrostatically to the surfaces of clay-like particles in the ore are released from the rock substrate in a putative electrophysical reaction in the presence of the oxidant. Some of the released bitumenous and kerogenic compounds are then controllably cleaved by the oxidant in a limited Fenton's reaction to yield organic compounds having lower average molecular weights which are suitable for refining as oil after separation from the process water phase and the residual rock substrate.

  • Patent number: 6243274
    Abstract: A plurality of shields is provided for shielding selected electronic components and electronic sub-assemblies mounted on a printed wiring board assembly from electromagnetic interference (EMI) and/or from radio frequency interference (RFI). The shields include open-ended electrically conductive casings having lower ends fixedly attached on the printed wiring board so as to surround selected components. A compliant electrically conductive member is positioned in common over upper ends of the casings. An electrically conductive housing disposed over the compliant member provides compression of the compliant member such that electrical contact is maintained between the housing on the upper ends of the casings. A grounded base plate is spaced from the wiring board assembly. The housing is removably attached to the base plate to provide the plurality of shields.

  • Patent number: 6235170
    Abstract: A hollow cathode magnetron for sputtering target material from the inner surface of a target onto an off-spaced substrate. The magnetron is in the shape of a truncated cone, also known as a conical frustum. The target cone is backed by a conical cathode maintained at a predetermined voltage for attracting gas ions into the inner surface of the target cone to sputter material therefrom. The inner surface of the cone is bounded at its inner and outer edges by magnetic pole pieces orthogonal to and extending inwardly and outwardly of the cone surface. The magnetic path is completed by a conical magnet surrounding the target and conical electrode and magnetically connected to the pole pieces to form a magnetic cage. Lines of magnetic flux extending above the target surface between the pole pieces are substantially parallel with the target surface, providing uniform erosion over the entire surface.

  • Patent number: 6224725
    Abstract: An improved unbalanced magnetron sputtering (UMS) apparatus in accordance with the invention having a conventional target and arrangement of magnets wherein a central portion of the target is backed by a first magnetic pole and the peripheral portion of the target is backed by a second magnetic pole, the poles carrying unequal numbers of lines of magnetic flux. One of the poles has a greater number of flux lines entering or leaving than does the other pole. The field lines extending from the higher flux pole which do not close in the lower flux pole extend into space in a range of directions and generally toward a substrate to be sputter coated. Adjacent the target and electrically isolated therefrom and overlying the higher flux pole is an independently-controllable auxiliary electrode, preferably a cathode, formed of a non-ferromagnetic material and having a surface facing in the same general direction as the sputterable surface of the target.
