  • Patent number: 4876891
    Abstract: An aerosol spray dispenser of flowable pharmaceutical product is provided with a flotation stabilizing arrangement such that it will float in water in a stabilized erect position even when empty of product; a scale is associated with the dispenser so that the depth at which it floats can be read by comparing the position of the surface of the water in which it floats with graduations on the scale. The stabilizing action may be obtained by placing the dispenser in a floatable bottom-weighted vial, with the scale located in the exterior of the vial, and the combination of vial and dispenser then floated in water. In other embodiments the vial need not be used, in which case the dispenser itself may be bottom-weighted to assure its stabilized erect flotation and the scale placed on the exterior of the dispenser; or, a cap may be provided for the dispenser which is positioned on the dispenser while both are floated in the water, the cap being top-weighted so that the assembly floats stably upside-down.

  • Patent number: 4856909
    Abstract: Standardized tests of the dissolution rates of pharmacologic dosage units such as salicylic acid tablets, for example, are conducted by placing the dosage unit in a liquid-permeable cylindrical wire basket and rotating the basket in the solvent about two different axes, preferably one vertical axis and one horizontal axis. The apparatus comprises an outer vertical tube to which the basket is mounted off center from the vertical axis of the tube so that it orbits around the vertical axis when the vertical outer tube is rotated; the basket is mounted on a horizontal shaft which can rotate about its horizontal axis. An inner shaft extends vertically through the outer vertical shaft, and bevel gears are provided between the horizontal shaft and the inner vertical shaft so that relative rotation of the upper ends of the inner and outer vertical shafts with respect to each other about their axes causes the basket to rotate about the horizontal shaft axis.
