Patent CA-2072711-A1 (CA)
Title: Electronic welding current generator for impulse arc welding
Inventor: STRUMPF HANS G
IPC: H02M9/00
Filed: 1992-06-29
Abstract: ABSTRACT      The invention relates to an electronic welding current generator for impulse arc welding and to a method of controlling the arc length during impulse arc welding using such an apparatus.  The welding current generator has a power component that is controllable by electric lead parameters which are preselected by way of electronic circuits, whereby during pulsed operation (T) a higher generator pulse current (Ip) or a higher generator pulse voltage (Up) is produced during the pulse phases (tp) and a lower generator base current (IG) or generator base voltage (UG) is produced during the base phases (tG).  On the basis of the Up-IG modulation, the pulse voltage (Up) is controlled during the pulse phases (tp) and the base current IG is controlled during the base phases tG. During the base phases tG, the base voltage is measured at selected times and the measured value (E) is stored and updated after each pulse period (T).  The updated measured value (E) of the base voltage (UG) obtained, is directly proportional to the real, active length (LL) of the arc.  This updated measured value (E) is used for the overriding control of the welding process in that the measured value (E), which represents the length (LL) of the arc, is compared with a selectively adjustable nominal value (SWLL) for the length of the arc and is amplified by a series PI-controller with the goal of achieving the mentioned superior lead control.  The arc length is maintained at a desired length and the warming of the welding cables and the wear of the contact nozzle no longer affects the arc length.  The operating life of the contact nozzle is increased.

Filed: 1992-08-28
Abstract: A subscriber loop tester for testing local loops of telephone switching networks has a partitioned "U" interface and an internal bus architecture for converting various transceiver circuit output data formats to a common data format.  The "U" interface has a high impedance transformer meeting bandwidth and line matching requirements for different line codes and protocols for ISDN telecommunication systems. The transformer is selectively coupled to option cards each containing circuitry having AC and DC terminations matching specific line codes and protocols for ISDN telecommunications systems and other types of telecommunications systems. The option cards further contain programmable attenuators for producing a proper nominal signal level as a function of the specific line code and protocol and providing variable insertion loss.  A high speed bus is selectively coupled to the option cards for coupling the formatted transceiver circuit output data between the cards and a digital bus translator.  The digital bus translator selectively configures the high speed bus for the transceiver output data format of the selected option card and converts the formatted output data received on the high speed bus to a common data format.  Multiple source and destination audio paths in the subscriber loop tester are controlled by an audio switching matrix.
