Abstract: Measured values are converted into electrical impulses for gauge devices and the like in a mechanism including a plurality of photocells arranged on a generally circular arc with a rotatable disc having angularly spaced radially extending slots arranged for movement relative to the photocells to energize and deenergize them in accordance with the angular spacing of the slots in the disc. Electrical circuitry operates to emit electrical impulses responsive to the energization and deenergization of the photocells and the photocells are mounted to enable their positioning relative to the rotational axis of the disc to be adjusted, thereby to enable adjustability relative to the emitting of the electrical pulses.

Abstract: An electromechanically driven digital indicating device comprising an arrangement of seven flaps electromagnetically movable to one of two defined positions. The flaps are disposed in a housing at one plane thereof so as to form an "8"-shaped figure. The device includes a deep drawn parallelopiped housing having a front window opening in the form of a parallelogram and having a plate with an elevated, freely accessible "8"-shaped contour constructed integrally with the housing. The plate is supported only at connecting rods at the rear of the housing in internal sides walls of the housing. On the reverse side of the bar-shaped contour, there are provided grooves into which bearing bolts of the flap elements are pivotally inserted.

Abstract: The fuel dispensing arrangement includes a fuel dispensing nozzle, a fuel pump for pumping fuel to the fuel dispensing nozzle, an electric pump motor operative when energized by pump motor current for driving the fuel pump, a price calculator and indicator arrangement for calculating and indicating the price of the fuel pumped through the nozzle, a resetting arrangement which can be driven to effect resetting of the price calculator and indicator arrangement, and an electric control motor operative for driving the resetting arrangement. A source of electrical energy is connected to the pump motor by way of a pump motor current path for the flow of pump motor current. The operation of the control motor is controlled in dependence upon the flow of pump motor current.
