Title: Interconnection between main and auxiliary supply on board ship - assists with correct monitoring of installation resistance under all auxiliary circuit operating conditions
Inventor: GRIGOREV EDUARD NIKOLAEVIC
IPC: G01R27/18
Filed: 1980-01-23
Abstract: The application is to a shipboard auxiliary system (2) which is connected to the primary system (1) by a static converter (10). For example a d.c. auxiliary system is fed by a controlled rectifier from a 3-phase primary supply. A connection is taken from one phase (4) of the primary through a resistor (17) to one pole of the secondary system (8). The value of resistance used is lower than the lowest permissable insulation resistance (12-16) between the supply networks and the ship's hull. When the converter is operating with large delay angle, or when at very low current the output can become discontinuous. The auxiliary circuit is then disconnected from the primary as at certain regular intervals all the converter valves are blocking. The proposed ohmic interconnection ensures that the two systems are always joined galvanically thus enabling earth fault monitoring unit to operate correctly.

Title: Electronic integrator operating without interface - has adjustable integration circuit generating integration and sign pulse
Inventor: WOEHRL ALFONS
IPC: G01R17/04
Filed: 1980-06-12
Abstract: This electronic integrator circuit operates directly in conjunction with a microprocessor without requiring an interface circuit. This is accomplished by integrating the time-variable analogue data during regular time intervals up to a threshold above which an integration pulse and simultaneously a sign pulse, corresp. to the positive or negative sign of the integration level, is generated and the integrator is reset. The resettable integrator (3,4,5) is coupled to a differential amplifier (6) and pulse shaping circuit (8) which determine the integration threshold and generate the integration pulse (Ji). This controls the reset switch (5) of the integrator. Another differential amplifier (9) and pulse shaping circuit (10) generate the sign pulse. Both pulses are synchronised by passing through a NOR-gate (11).
