    摘要: An ink tank and ink tank support structure which contains structural elements which are designed to permit proper installation of the ink tank in the ink tank support structure while minimizing the chances of improper installation of the ink tank in the ink tank structure. A primary ink tank seal is provided in the ink tank, and a relatively low compressive force seal is provided between the ink tank support structure and the ink tank to reduce leakage of fluid from the tank and limit evaporation of fluid from the tank despite repeated insertions and removals of the ink tank from the ink tank support structure. A variable capacity ink tank and an ink tank with staggered height walls are disclosed, as well as a code reader for determining characteristics of ink tanks.

    摘要: A calibration method and apparatus for economical and rapid calibration of a scientific instrument utilizing a monochromator to generate monochromatic light utilizing controllable means for determining the angular position of a light dispersing element in the monochromator and a filter having a narrow absorption band(s) to determine a relationship between the wavelength of the monochromatic light generated by the monochromator and an angular position of the dispersing element so that the dispersing element can be rotated to an exact position for the monochromator to generate a selected wavelength of monochromatic light.

    摘要: A biological indicator is made of a vial which contains a "spore dot", a nutrient solution in a frangible ampoule, and means for positioning the spore dot and for breaking the ampoule to release the nutrient solution when the cap of the vial is fully pressed on. The nutrient solution typically contains a pH indicator to determine whether all active spores on the strip were killed by a sterilization process which takes place prior to breaking the ampoule.

    摘要: A steel plug is inserted into a modern shotgun to convert it into a muzzleloading firearm. The plug is made for use as a breech plug in a single barrel shotgun without modifications to gun. The plug enables the shotgun to be used as a muzzle-loader with black powder and allows conversion of the gun back to its original condition by simply removing the breech plug.
