  • Publication number: 20190117353
    Abstract: A dental floss produced with dips, rises and knobs used for dental hygiene. The dental floss may be made of two polymers (synthetic compounds), either Nylon or Teflon. The dental floss is designed for removing debris and plaque from between the teeth and between the teeth and gums. (I would not what to be restricted from using other materials should they be developed in the future. (Flosses have been made up silks, etc. in the past).

  • Publication number: 20140377470
    Abstract: An apparatus and method provide an adjustable, aimed, lighting system that may be selectively secured to and removed from the ferrule of a paintbrush for illuminating the edge of the bristles during a cutting-in process. The light may be moved as appropriate, and may be aimed to ride with the brush, thus illuminating directly at the edge where paint is being deposited. Thus, precise deposition of paint may be done in spite of the shadows cast by the body of the painter and the bulk of the brush during much of such cutting-in procedures.

  • Patent number: 4756374
    Abstract: A device (10) for providing an indication of loads exerted on a vehicle frame (12) comprises a sensing unit (22) mounted to and between the frame (12) and the vehicle axle (14) and for detecting vertical displacement of the frame (12) relative to the axle (14) when loads are exerted on the frame (12). The sensing unit (22) comprises an arm (126) pivotally mounted to the frame (12), through a pair of telescoping tubes (32, 44), and an adjustment rod (124) movably mounted to and between the arm (126) and the axle (14). When a load is exerted on the frame (12), the same depresses relative to the axle (14) and the arm (124) rotates. Rotational movement of the arm (124) is measured by a clinometer (128) mounted thereto and which converts the angular measurement into a coherent digital or analogue readout displayed by a receiving unit (26).
