  • Patent number: 6199266
    Abstract: A superconductor cable with high interstrand resistance is produced from superconductor wire strands which has been electroplated with nickel. The wire strands have filaments of a superconductor alloy in a normally conducting metal matrix and are electroplated before they are formed into an elongated bundle of generally circular cross section. This bundle is then deformed and compacted into a superconductor cable of generally polygonal cross section which is usually trapezoidal. The superconductor wire is preferably comprised of a multiplicity of filaments of niobium/titanium superconductor alloy disposed within a matrix of copper.

  • Patent number: 6178386
    Abstract: A partial discharge fault in a transformer tank is determined by sensing supersonic vibrations at a multiplicity of points about the tanks and establishing a threshold amplitude and a frequency range for pulse vibrations to be evaluated. The signals from the multiplicity of points are multiplexed, synchronized and localized and then processed in a series of steps. After the existence of triggering pulse vibrations exceeding an established threshold amplitude and within an established frequency and range is initially determined, a wavelet transform is conducted on the multiplexed signals two at a time with one signal being the signal from the first sensor found to provide a signal above the threshold amplitude. The wavelet transform provides both frequency and time domain.

  • Patent number: 6168006
    Abstract: A machine tool/parts sorter assembly includes a machine tool having a frame and a workstation at which multiple parts are cut from a workpiece as it is moved in a horizontal plane relative to the workstation. A sorter is coupled with the machine tool frame for separately guiding different parts to different discharge areas adjacent the machine tool. The sorter includes a guide member adjacent the workstation for receiving the parts from the workstation, a pair of spaced, downwardly inclined guide chutes for discharging parts to separate discharge areas, and an actuator for selectively moving the guide member to discharge parts thereon into the guide chutes.

  • Patent number: 6151849
    Abstract: A composite door with a lite utilizes panels with aligned cutouts and a foam retainer member which extends about the cutouts between the panels to effect a seal. The retainer has a mounting portion extending inwardly from the cutout periphery. The lite is disposed in the cutout and it is secured by an external frame which has portions overlying the outer surface of the panel and its marginal portion. A clamp secured to the foam retainer and external frame and clamps the lite to the external frame, and an internal frame has portions overlying the outer surface of the other panel and the marginal portion of the other surface of the lite and conceals the clamp and fastener.

  • Patent number: 6117506
    Abstract: A bottle for protecting its contents from degradation due to light has an integrally molded wall with three layers of the same synthetic resin. Each of the layers includes a colorant, the colorant of the intermediate layer providing a generally black opaque coloration and the colorant of the inner and outer layers providing a generally white opaque coloration to mask the black coloration of the intermediate layer.

  • Patent number: 6085873
    Abstract: A pneumatically operated elevator has a pair of elongated vertical tubular cylindrical shafts and horizontally extending cross-over shafts extending between the vertical shafts adjacent their upper and lower ends to provide a substantially closed system. A cab is disposed within one of the vertical shafts, and a fan in at least one of the cross-over shafts moves air between the ends of the shafts to produce a pressure differential above and below the cab to cause the cab to move upwardly and downwardly in the one shaft. At least one vent is provided to admit air into at least one of the shafts to compensate for leakage from the shafts.

  • Patent number: 6035539
    Abstract: A naturally illuminated three dot sighting system for firearms includes a rear sight having two dots formed by scintillating fibers encased in an optically clear polymer block, and a front sight having one dot formed by a scintillating fiber within an optically clear polymer post. The rear sight has a center channel with scintillating fibers disposed on each side thereof. In poor ambient light, the light incident on the optically clear blocks travels to the fibers which gather such light and scintillate to provide dots of light at their proximal ends which can be aligned.

  • Patent number: 6019243
    Abstract: A spill containment receptacle for use with a tank has a flexible receptacle member defining an enclosure. It has a bottom wall and a sidewall extending upwardly and inwardly from the periphery of the bottom wall to a height that is less than the width of the bottom wall. The upper end portion of the sidewall has a collar extending thereabout and defining on opening adjacent the upper end of the receptacle member which is of lesser area than the bottom wall. Straps are attached to the collar for securing the receptacle member to an associated tank. The opening of the receptacle member is positioned directly beneath a point of leakage from the tank, and the upper end of the sidewall is positioned adjacent the surface of the tank about the point of leakage.

  • Patent number: 6012653
    Abstract: A modular abrasive agent water jet cutting head (1) has a nozzle (4) issuing a high-speed water jet (16), a mixing chamber (10) through which the high speed water jet passes (16), an abrasive agent supply line (14), and a focussing nozzle (15) forming the outlet of the mixing chamber (10). A dosing unit (12) has an axial passage of the high-speed water jet (16). The passage (18) has one or more expansions or channels (11) extending radially and which are of reduced cross section at the passage. There are preferably in each case are formed as a slits, which are only slightly wider than the diameter of the thickest abrasive particle. The expansion or channel (11) is closely connected to the passage of the high-speed water jet (16) and introduces the abrasive agent into a chordal section of the water jet (16) which is oriented in the direction of the cutting action. From there the high-speed water jet (16) receives a track of abrasive agent on its surface.

  • Patent number: 6008465
    Abstract: A resistance measuring device is coupled with a controller for controlling the parameters of the cutting process. The device is connected between the laser cutting head of the machine of an electrically conducting part of the laser cutting head and workpiece, and the amount of the electrical resistance of the medium between the laser cutting head and the workpiece can be determined when cutting electrically conducting workpieces. In this method, the amount of the electrical resistance of the medium between the laser cutting head and the workpiece is determined, and the distance between the cutting head and workpiece is also determined. Depending on the detected values of the electrical resistance and distance, the parameters of the cutting process are controlled to obtain efficient cutting action.
