Abstract: An apparatus and method for the cordless remote control of a filling function of a mobile vehicle that includes a signal transmitter (12) and a liquid level sensor (14) that is mounted on a tank (18) of a mobile vehicle (16). The liquid level sensor (14) transmits a full signal to a remote signal receiver (22) by way of the signal transmitter (12). The full signal closes a control valve (26) interupting the flow of the fluid to the tank (18) by way of a conduit 28. An adjustable timer (44) provides a system safety back-up signal that closes the valve (26) if the full signal is not received within a preset time period. This apparatus and method can be operated in a semi-automatic mode or an automatic mode by the addition of an adjustable delay clock/timer (42). Audible and/or visual indicators are provided for monitoring the status of the filling operation.
Abstract: A partially cutaway circular cylindrical tool for changing the master pins in an Almont lock is presented. The tool is fixedly coupled at one end along its axis to a handle which may be a key handle. At the opposite end, the tool comprises a plug stop which prevents the tool from going too far into the Almont lock. The partially cutaway circular cylindrical surface defines a master pin slot, two wire slots, a wire slot ridge, a stationary pin slot, and a pin holding cam ridge, which includes a cam adjacent to the master pin slot all parallel to the axis. Perpendicular to the axis and disposed about halfway between the end of the plug stop inserted into the lock and the point of coupling between the handle and the balance of the tool is a perpendicular stationary pin slot which entends between the master pin slot and the stationary pin slot. In operation, the tool is inserted into the Almont lock and rotated so that the master pins, which are wafer tumblers, slide up the master pin slot.
