Abstract: A surge suppressing device includes a voltage-dependent resistor having an opening formed therethrough. A pair of preformed pads formed of an electrically conductive material is located adjacent a first and second side respectively of the voltage-dependent resistor proximate the opening. The electrically conductive material flows through the opening creating an electrical short between the first and second sides when the voltage-dependent resistor is heated in response to excessive leakage current flowing therethrough.

Abstract: A dispensing system for controlling and displaying information regarding self-service operation of each of a plurality of fuel dispensers in a gasoline station includes, in one embodiment, an operator console having a CRT display displaying the status of each of the dispensers as well as current and previous sales data and a data entry keyboard for entry of sales and other data together with switch means for arming dispensers for self-service operation and for actuating the system for displaying selective dispenser information. The CRT and data entry keyboard are coupled to a central control unit which includes a programmed memory central processing unit for handling data between the central control unit and each of a plurality of dispensers as well as dispenser communications interface circuits.
