Title: A subscriber connection circuit for an exchange of a telecommunications system
Inventor: LECHNER R
IPC: H04M19/00
Filed: 1980-03-21
Abstract: A subscriber line access circuit for use in a telecommunications system is disclosed. The subscriber line access circuit has a power supply bridge in the form of a first resistor inserted in the b-wire (ground potential side) of a subscriber line, a second resistor inserted in the a-wire (supply potential side) of the subscriber line, and a capacitor which bridges the two wires at the terminals of the two resistors on the sides thereof opposite to the respective potential sources. This supply bridge is coupled on the capacitor side with a two-to-four wire hybrid transformer for the two-wire/four-wire transition to the system, and includes an evaluating circuit which delivers an indicating signal when the subscriber actuates a ground key. A cutoff circuit is arranged in the power supply bridge in series with the first or the second resistor, or both, between such resistor and the winding of the hybrid transformer to which it, the resistor, as well as the evaluating circuit are connected. This cutoff circuit comprises a cutoff switch which is opened, with a delay, upon ground key actuation and closed when the ground key actuation is terminated.

Title: Detecting tampering of kilowatt-hour meters
IPC: G01R21/00
Filed: 1979-01-11
Granted: 1982-11-10
Abstract: To detect tampering of a kilowatt-hour meter by the connection of a bypass link across the live connection through the meter, a voltage transformer within the meter unit is coupled to this live connecton so that a small volage is induced in the live connection in opposition to the supply voltage. The induced voltage produces a circulating current in the loop formed by the live connection and the bypass link and the transformer coupling is such that, with a bypass link of negligible resistance, the total current in the live connection is in opposite phase to the applied voltage. By means of a current transformer, a logic unit and a microprocessor, the phase of the current in the live connection within the meter is determined and is indicated by a latched flag indicator and/or transmitted to a distant data processor by a data link. Using a second current transformer in the return supply lead, the supply and return currents in the leads within the meter unit can be compared in the logic unit and processor to determine if the live connection is broken within the bypassed length. By means of contacts on the housing, indication is given if the housing of the unit has been opened.

Title: Fuel injection pump for internal combustion engines
Inventor: HOEFER GERALD
IPC: F02B3/06

Granted: 1991-06-05
Abstract: A fuel injection pump of the distributor pump type having a pump piston driven for simultaneous reciprocation and rotation, the supply quantity of which that is effective for injection is controlled by the opening of a relief conduit of the pump work chamber in that with the aid of a mechanical regulator an annular slide is moved into variable stroke positions on the pump piston. Additionally, for an electronic regulation of the total injection quantity, a pre-stroke (hv) is provided, which is determined by a first valve and which, under the control of a second, electrically controlled valve connected to the output side of the first valve, is added to the basic supply stroke in a variably effective manner in terms of injection. Thus the fuel injection quantity can be regulated within the context of the fuel injection quantity difference resulting from the pre-stroke.
