  • Patent number: 5710195
    Abstract: This invention applies to methods for creating opaque indicia on substrate surfaces and to non-pigmented, moisture-free, jet ink compositions containing only solvents and solvent soluble resins and dyes that exhibit the acceptable characteristics of opacity, contrast, adhesion and machine compatibility. The compositions are on weight percentage basis as stated below. The compositions contain a combination of film forming resins of varying molecular weights of a dry resin solids percentage between 8 and 15%. The resins are chosen from the following: nitrates of cellulose; acrylics; alkyds; vinyl acetate-vinyl chloride copolymers; and styrene acrylic. The quantities of resin are chosen according to the desired viscosity, adhesion strength of film on the subject substrate and the degree of shearing of the drying resin mixture. An optimum balance of adhesion and opacity is stoichiometrically obtained.

  • Patent number: 5616083
    Abstract: An apparatus for generating a deep U-shaped vortex, with the vortex being of sufficient height to include a relatively large air well in its center. The apparatus may be used as an amusement park ride, wherein it comprises an observation platform, a large vessel partially filled with liquid, and an impeller to rotate the liquid within the vessel and thereby create a vortex of liquid within the vessel. When the vortex is created, an air well develops in the center of the vessel, with the air well being of sufficient size to allow the entry of the observation platform therein, with the observation platform being surrounded below and at its sides by the rotating liquid, but without coming into contact with the rotating liquid.
