Title: Electronic postal meter system
IPC: G06F11/08
Filed: 1978-10-27
Abstract: An electronic postal meter system is separated into a meter unit and an input/output control unit. The two units are linked by a communications link which preferably uses light transmitting fibers to transmit data and instructions. The meter unit is used to process and store only that data which pertains to the critical accounting functions of the meter or to the control of the printer driven by the electronics control within the meter unit. Less critical functions, such as zip-to-zone conversions, are restricted to the less secure control unit. By restricting the meter unit to highly critical data and by enclosing only the meter unit in a secure housing, the overall security of the meter system is enhanced. Failure detect circuitry for a printer setting detector array and an event-indicating signal generator circuit are disclosed. The significant routines employed in the operation of the meter system are described.

Title: Measuring vehicle fuel quantities
IPC: G01F17/00
Filed: 1978-11-23
Abstract: The quantity of fuel in a vehicle tank 10 is computed in an evaluation circuit 40 from the signals from transducers 11, 12 proportional respectively to the quantity of fuel filled into the tank and the quantity of fuel drawn by the engine. The evaluation circuit comprises an up-down counter which counts "up" when the tank is filled, the direction of count depending upon whether the vehicle ignition is switched on or off. The quantity of fuel is displayed on a voltmeter 30 or alternatively on a digital display which forms part of an indicator 20. The up-down counter is reset by the tripping of one of two depth switches 17, 18. The signal proportional to fuel drawn from the tanks is also used to provide an indication of fuel consumption rate. The indication is in the form of illuminated elements 21 each being associated with a speed of a speedometer and each element 21 indicating the optimum fuel consumption rate at the associated speed. A further illuminated element 22 indicates an abnormal fuel consumption rate. <IMAGE>

Title: Improvements in or relating to binary adder circuits
IPC: G06F7/502
Filed: 1979-03-13
Abstract: A binary adder circuit which, in response to a mode selection signal, is forced to operate as if two of its inputs were equal, irrespective of the actual value of those inputs. In this condition, the circuit acts effectively as a connector, coupling its input C direct to the sum output and the OR of its inputs A, B to the carry output. The invention is useful in a circuit arrangement for performing adding and shifting operations in which with X = 1 and B = 0 for all stages, input A of stage i becomes input (i+1) and hence the sum output of the latter stage. <IMAGE>

Title: Piston and cylinder seal
IPC: F16J15/32
Filed: 1979-08-14
Abstract: A seal for use between the piston 6 and cylinder of a hydraulic brake master cylinder comprises: an inner annular portion 2 which is located in a groove 5 in the piston; a web portion 4 which extends radially outwardly and axially forwardly from the inner annular portion; and an outer annular portion 3 which extends radially outwardly and axially forwardly from the web portion.
