  • Patent number: 5937866
    Abstract: A hair dye applicator has a container having a variety of interchangeable components through which hair dye is discharged onto the hair. A first interchangeable component has a roller ball and is ideal for use when distribution of hair dye along a part at the root of the hair is desired. A second interchangeable component has a plurality of flexible brushes, and is ideal for distribution of hair dye throughout the hair and along the hair shafts. A third interchangeable component has a plurality of rigid combs, and is ideal for overall distribution of hair dye in coarse or thick hair. Both second and third interchangeable components contain a moveable disc which allows a user to control the rate of discharge of hair dye from the hair dye applicator. The hair dye applicator of the present invention has a lid that may be utilized to prevent spillage and to slow oxidation of unused hair dye which may be needed throughout the hair coloring process.

    Abstract: An apparatus and method to enable investigators of medical and insurance fraud to quickly and reliably determine whether a plurality of signatures affixed to a series of documents were made with the same pen and/or at the same time. According to a first embodiment, a series of indentations are formed around the periphery of the rim at the forward end of a conventional ballpoint pen. The indentations produce radially inward extending projections which are aligned with the rolling ball of the pen to induce scratches or micro-striations in the ink lines applied to the paper from the ball. By analyzing the scratch patterns of different signatures applied by the same maker to different documents, an indication can be provided whether the signatures were all made with the same pen.

    Abstract: The present invention relates to improved product dispensers for various spreadable products, including fluids, suspensions, lotions, creams, emulsions, and gels. In a preferred embodiment of the present invention, the dispenser is in the form of an improved roll-on type applicator with an enlarged application/distribution surface in the form of a dome with an aperture for exposing a portion of the rotating element. As product is expressed from the gap between the element and dome, it follows the surface of the element into contact with the desired surface and is thereby applied to this surface. Excess product not applied to the desired surface by the element either follows the element surface through the gap between the element and the dome back into the container or is sheared from the element surface by the edge of the aperture in the dome.

  • Patent number: 5308179
    Abstract: A writing instrument shaped to resemble a flower on a stem with leaves comprised of a hollow tubing housing, a top portion of hollow tubing, an adapter for detachably connecting the top portion to the housing, and a stylus. One portion of the housing is curvilinear, having a plurality of loops shaped to resemble leaves. The top portion is shaped to resemble a flower or bud. The adapter allows the top portion to be detachably connected to either end of the housing. The overall effect is to suggest a flower or bud on a stem with leaves. A second embodiment of the writing instrument uses a base formed of hollow tubing bent into shapes to complement the flower and stem suggested by the housing and top portion. A third embodiment includes a plurality of top portions which are interchangeable and can be detachably connected to the housing using the same adapter.
