Abstract: An attendant-controlled terminal, operating under the control of a conventional microprocessor, monitors and controls remote fuel pumping units, combines fuel sale information with information concerning additional sales keyboarded by the attendant, accepts customer account information recorded on a credit card, verifies that the identified account is in good standing, and prints a credit card receipt for signature by the customer, the receipt being printed in an optically-readable format compatible with conventional automated invoice processing equipment.

Abstract: A flow responsive counting apparatus comprising in combination a) conduit means having an inlet and an outlet; b) means mechanically responsive to fluid flow for measuring volumetric flow of water; c) means mechanically responsive to fluid flow for totalling "on-off" water flow cycles; said conduit means interconnecting in series the means for measuring volume flow and means for totalling on-off water flow cycles. The apparatus interconnected in an appropriate water line in an automatic car wash can provide a tamper-resistant means for counting the number of vehicles washed in the automatic car wash.

Abstract: A method of reformulating a gasoline is provided to form a reformulated gasoline having as compared to the gasoline a reduction, upon burning and exhausting from a vehicle, of both hydrocarbon mass and reactivity of vehicle exhaust emissions and simultaneously a reduction of vehicle exhaust emissions of toxics, carbon monoxide and nitrogen oxides, wherein said gasoline comprises a concentration of aromatic compounds, olefinic compounds, and sulfur or sulfur-containing compounds and may be characterized by a 90 percent distillation temperature, said method comprising (a) reducing said concentration of aromatic compounds; (b) reducing said concentration of olefinic compounds; (c) reducing said concentration of sulfur or sulfur-containing compounds; (d) reducing said 90 percent distillation temperature; and (e) adding an oxygenate. A reformulated gasoline formulated by use of such method is also provided.
