Abstract: A universal hose adapter includes an upper member for permanent mounting on the piping housing of a blending type gasoline dispenser, and a plurality of lower members each mateable to the upper member, and each configured for permitting retrofitting of the dispenser to accept a particular hose configuration, in modifying the dispenser system. The upper member includes a vapor return outlet port for connection to the dispenser's vapor return line, if any; a vapor return outlet port; a plurality of gasoline input ports for connection to gasoline lines of the dispenser carrying different grades of gasoline, respectively; and a plurality of gasoline outlet ports associated with each gasoline inlet port, respectively.

Abstract: Linear sensing apparatus for a positive displacement meter includes relative to each piston of the meter, an elongated rectangular member rigidly attached at one end to the top face of its associated piston, and carrying at its other end a multiwindowed member that reciprocates back and forth with movement of the piston for alternately interrupting detectable energy flowing between energy transmitting and detecting devices, the detecting device converting the detected energy into alternating electrical signals analogous to the volume of fluid passed through the meter, whereafter the signals are processed via a microprocessor for obtaining the actual volume and/or price of the fluid passed through the meter over a given period of time.
