Abstract: A gauge assembly includes an indicator for providing an indication of an amount of fluid in a tank and a stop-fill assembly for stopping the flow of fluid flowing into the tank once the fluid reaches a particular level. The gauge assembly has a shaft that rotates as the fluid level changes in the tank. The indicator translates the rotational position of the shaft into a fluid level. The stop-fill assembly moves from an open position, where fluid can flow into the tank, to a closed position, where fluid is prohibited from flowing into the tank, depending on the rotational position of the shaft.

Abstract: A combination tank valve apparatus providing fluid flow control, overfill protection, and fluid level gauging for use on a storage tank for liquefied gas, the storage tank having an internally threaded outlet port. The apparatus includes a service valve having a body defining a tank connection, a valve seat, a valve outlet, and a pair of wrench flats. The apparatus also includes an overfill protection device mounted to the tank connection of the service valve and including a float, a shaft, a overfill valve, and a shaft magnet. The apparatus also includes a dial mounted on the body of the service valve and having a body, a dial magnet, and a pointer, the pointer being mounted on the dial magnet to rotate with the dial magnet and provide a visual indication of the liquid level within the tank.

Abstract: A system for determining a fluid level in a pressurizable container comprising is disclosed. The system includes a service valve having a set of wrench flats defining parallel flat surfaces, one of the wrench flats having a recess defined entirely within its flat surface, a stop-fill device interconnected with the service valve and operable to rotate a first magnet inside the service valve in proximity to the recess in proportion to the amount of fluid in the pressurizable container, and a dial assembly having a dial face and a pointer attached to a second magnet, the second magnet housed in a magnet protrusion on a side of the dial face opposite the pointer and operable to fit into the recess in the service valve such that the dial moves on the dial face proportionately to the degree of rotation of the first magnet inside the service valve.

Abstract: A pen-based portable computer, or pen-tablet computer, for use with a vehicular docking station that allows for the exchange or replacement of components thereof without the need for returning the computer to the manufacturer, is provided with exterior, removable grips that not only provide a gripping function, but also provide shock-absorption and protection exteriorly of the computer-housing. Each grip may be selectively removed from attachment to the computer-housing, in order to allow access to the interior of the housing for repair and maintenance. Four such removable grips are provided, where each grip is provided with an actuable lever for removably locking the grip to a portion of the computer housing, with each actuable lever being capable of movement away from such locking engagement in order to allow removal thereof from the housing.
