  • Lug nut covers
    Patent number: 5380070
    Abstract: A vehicle wheel lug nut cover comprises a dome shaped tube having an open end that is larger than the lug nut and a closed end with an internal jam nut that is threaded to the end of the lug bolt extending from the lug nut.

  • Dispensing cartridge filling system
    Patent number: 5341859
    Abstract: Apparatus for filling tubular dispensing cartridges with paste or viscous fluid comprises a mandrel adapted for a sliding fit within the cartridges, the mandrel having an axial fluid passage and a parallel air passage which extends from the mandrel top to an radial opening near the mandrel bottom surface. A pneumatic control system controls the amount of paste or fluid by sensing the flow of air through the air passage. If air passes through the passage, the fluid valve is closed; if air is blocked by a cartridge on the mandrel, the fluid valve is enabled and a manual control valve may be used.

  • Method for determining absolute reflectance of a material in the ultraviolet range
    Patent number: RE34783
    Abstract: A method for determining a value of absolute reflectance of a material at .[.a predetermined.]. .Iadd.any .Iaddend.wavelength, in the ultraviolet range from its measured reflectance which includes system losses contributed by optics, illumination sources, detectors, etc. The method involves the measurement of reflectance from a known material such as single crystal silicon whose absolute reflectance is well known, dividing the measured value by the absolute value to obtain a system efficiency coefficient at the known wavelength and then, without changing the illumination or optics, measuring the reflectance of the unknown material and applying this coefficient to this measured value to obtain its absolute value.
