Abstract: The present device provides a safe, effective means of mobile ultraviolet (UV) disinfection. A control board within the main body of the device receives data from sensors that may variously measure orientation and speed of the main body as it moves along various surfaces for disinfection. In response to such data, the control board may brighten, dim, or completely shut off UV light-emitting diodes (UVLEs), both to prevent over- and under-exposure of the materials being disinfected, and to prevent a user from unsafely using the device.

Abstract: Apparata and methods are shown and described for converting closed-topped containers, e.g., common aluminum beverage cans and steel food cans, into open-topped containers having open top mouths surrounded by a smooth rounded lip. In a preferred version of the invention, a closed-topped container, e.g., an aluminum can, is inserted within a casing so that its top protrudes outwardly therefrom. A tubular ram having a cutter situated therein is inserted over the can top and rotated with respect to the can to sever the can top from the remainder of the can. The ram is then withdrawn and inverted to reveal an annular bending groove facing the cut upper can sidewall. The ram is then screwed onto the casing to bring the bending groove onto the cut upper can sidewall, thereby bending a rolled lip on the can sidewall. The closed-topped can is thus converted into a cup-like open-topped container.

Abstract: A tape winder including a supply spindle for supplying tape, a take-up spindle for taking up tape from the supply spindle, and opposing sidewalls with slots therein wherein the spindles are rotatably received. A drive mechanism located on the sidewalls engage the spindles when the spindles are fully inserted within the slots. The slots preferably include a narrow throat region near their openings so that the spindles may be snap-fit within the slots. The supply spindle is preferably driven with lesser torque than the take-up spindle so that the difference in relative torque between the spindles maintains tension in the tape and causes it to wind tightly.

Abstract: A fluid flow indicator is presented particularly for use within an existing gasoline pumping apparatus. The fluid flow indicator includes an outer cage member, a first hollow transparent cylindrical member contained within the outer cage member, and a second hollow transparent cylindrical member concentrically retained within the first hollow transparent cylindrical member. The fluid flow indicator may also include a filter member and fluid movement detection means contained within the second hollow transparent cylindrical member. The fluid flow indicator is especially designed to be retrofitted within any existing fluid flow line.
