  • Method for determining absolute reflectance of a material in the ultraviolet range
    Patent number: 5045704
    Abstract: A method for determining a value of absolute reflectance of a material at a predetermined 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.

  • Lottery selecting dice
    Patent number: 4989874
    Abstract: A set of lottery game dice to aid in selecting six numbers between "one" and "forty-nine" to "fifty-three" are regular decahedron shaped. The total of the numbers displayed on the six dice are obtained by using some dice having eight surfaces displaying numbers and some displaying nine numbers. The dice are formed by providing one or two of the ten surfaces with an extending convex numbered surface to prevent the die from settling on that surface, thus eliminating one or two available surfaces for display.

  • Ventricular venting loop
    Patent number: 4985014
    Abstract: A catheter and fluid pumping apparatus and the method for bypassing portions of the heart to temporarily reduce the work load on the heart muscle. A double tube catheter is introduced into the femoral vein or artery and is advanced into the ventricle where blood is drawn and mechanically pumped back into the heart at a position downstream, such as the aorta or the pulmonary artery. The desired cardiac circulation can be maintained while relieving the load on the heart muscle to enable it to rebuild its strength.

  • Vehicle wheel cover
    Patent number: 4961611
    Abstract: Ornamental auto wheels mounted with conventional lug bolts or nuts and designed to be used without wheel covers are provided with ornamental wheel covers that cover only the lugs and hub area to discourage theft of the wheels. The end of a threaded shaft is attached to the center of an elongated bar which may pass through the hub hole at an angle and which is axially locked in the hub hole and against the rear surface of the wheel by a front plate screwed onto the shaft. The wheel cover to be mounted has a flanged tubular shaped nut retaining cup which has a central hole that will pass only the smaller diameter of two diameters of a locking nut which is threaded onto the shaft to secure the wheel cover to the wheel. The larger outer end of the nut closely fits within the larger diameter of the retaining cup, the outwardly extending flange of which prevents its passage through the wheel cover.
