Abstract: A gauge is disclosed for measuring squareness of a skate blade that has a pair of parallel side walls and a pair of bottom blade edges. The gauge includes a squaring frame that has a vertical blade contact surface fixed to a gauge plate. The gauge plate has a horizontal top surface. The vertical blade contact surface is selectively fixed to one of the side walls of the blade with a magnet having at least two parallel faces. Such a magnet is fixable between the skate blade and the blade contact surface. The gauge further includes a blade angle indicator having a flat lower surface and a parallel flat upper surface. Preferably the squaring frame of the gauge further includes an oblong vertical pivot aperture therein and the blade angle indicator includes an aperture therein, such that the squaring frame and the blade angle indicator may be pivotally fixed to each other with a pivot means.
Abstract: An adjustable scrubbing implement for cleaning a surface is disclosed. A resilient base that comprises a center portion and a plurality of resilient fingers each is joined at a proximal end thereof to the center portion and extends radially away therefrom. The rigid cap comprises a side portion fixed at a top end thereof to an inside upper side of the cap, and terminates at a wider open lower end. The inside upper side includes a central aperture therethrough. The cap includes a handle receiving means pivotally fixed thereto for receiving a threaded end of an elongated handle. An adjustment means interposed between the cap and the resilient base moves the center portion of the base relative to the inside upper side of the cap. The downward angle of the fingers are defined by the relative distance between the center portion of the base and the inside upper side of the cap.
Abstract: A tire pressure control system for a tire mounted to a wheel of a vehicle is disclosed. The tire pressure control system comprises a servo system mounted to the wheel that includes a servo mechanically connected to a vent valve that is in fluid communication with a gas inside the tire. The vent valve is adapted for bleeding the gas out of the tire and into the ambient atmosphere. A pressure sensor is in fluid communication with the gas inside the tire, and a control circuit is electrically connected to the servo and the pressure sensor. The control circuit further includes a signal receiving means and a memory for storing a commanded pressure signal. The control circuit actuates the servo to open the vent valve when the pressure sensor indicates a tire pressure of greater than the commanded pressure. A master control unit is adapted to transfer the commanded pressure signal to the control circuit through a transmission means.
