Abstract: A Portable Scoreboard that is capable of displaying critical information about the game in real time, either through manual input or through a Wi-Fi connected device. In the preferred embodiment, the Portable Scoreboard is made of light weight, pliable, and waterproof material. In one or more embodiments, the Portable Scoreboard comprises multiple lights to ensure its visibility and may further comprise a solar charging grid for lengthy outdoor events and continuous battery charging. In other embodiments, the Portable Scoreboard may be plugged in to an electrical source for recharging and/or power.

Abstract: The present invention relates to a vacuum pump comprising a turbo molecular pumping mechanism wherein an operative characteristic of the turbomolecular pumping mechanism is dependent on the orientation of the vacuum pump and the pump comprises an orientation sensor for sensing the orientation.

Abstract: In one embodiment, the musical box includes a box-like support structure and a music device disposed in the interior of the structure. A plurality of flexible continuous webs are sized to wrap around the outside of the structure. Each web has, along its outside surface, indicia representative of a particular mathematical data table, such as a multiplication table. One column of the table indicates the mathematical resultant of the remaining laterally displayed data. The resultant is disposed proximate a side of the support structure. A controllably movable strip or continuous web has a window and the window is sized to reveal one mathematical resultant. This continuous windowed web is driven by a gear and knob actuator.

Abstract: Modular circulating and dead end color changers are made from synthetic materials inert to chlorinated hydrocarbon solvents. Universal supply and return manifolds have relatively smooth and uninterrupted walls defined, in part, by inlet and return valve surfaces, for easy solvent flow cleaning. Circulating high pressure color changes have improved actuators and circulating means including bypass lines for continuously recirculating both selected and non-selected paints. Valve sealing is enhanced by improved valves and pressure drop across each module is minimized by modular construction regardless of the number of modules used.

Abstract: The invention relates to a projectile target game of the dart type which has individual player score keeping apparatus that includes a pair of nonrotatable shafts around which are loosely carried continuous belts which have an opaque background through which transparent numbers have been formed. Each digit of a number has a width substantially greater than the digits height. The continuous belt passes between a light source and a unidirectional magnifying lens which magnifies only the height dimension of the number's digits. The continuous belt is provided with score advance openings that are exposed via a slot in the face of the game that supports the target. The score advance openings are adjacent the transparent numbers such that a score may be made to appear in the magnifying lens. The target of the dart game is a dart board which has a unique bullseye target deflection detection mechanism.

Abstract: The drawings illustrate an odometer for vehicle use, including an idler wheel mounted adjacent the highest-order number wheel, and an endless strip of flexible material mounted around these wheels having a length equal to an integral multiple of the circumference of the highest-order number wheel. An array of indicia is formed on the strip for each rotation of the highest-order number wheel, and distinctly marked to portray, for example, that a second revolution of the highest-order number wheel is in progress.
