Title: Electrical heating body, end connection therefor and a method for connecting a conductor, which is fed in from the exterior, inside the heating body
Inventor: DESLOGE GEORGE B
IPC: H05B3/04
Filed: 1981-04-29
Abstract: The invention creates an electrical heating body having a heating element, a jacket which surrounds it at a distance and has an end piece which projects beyond one end of the heating element, an inner contact pin which extends in the direction of the end piece of the jacket, and an insulating plug which is inserted into the end piece of the jacket. On the inside, the insulating plug has an opening for accommodating the end piece of the contact pin, and on its outside, it has an opening whose centre line is offset with respect to the centre line of the contact pin and part of whose circumference is bounded by a side surface of the contact pin and which has such cross-sectional dimensions that the inner connecting part of a conductor fed in from the outside can be inserted therein with a snug fit. The insulating plug and the part of the jacket surrounding it can be deformed permanently to a smaller cross-section by radial compression, so that the reduction in the cross-section of the opening in the insulating plug caused thereby makes it possible to produce an overlapping connection between the connecting part of the conductor and the inner contact pin, within the insulating plug. The invention furthermore creates a method for connecting a conductor, which is fed in from the outside, in an electrical heating body, an end connection which can be used for the method, and a device for manufacturing such an end connection.

Patent DE-3206684-A1 (DE)
Title: Identification method for converter actuators with a pulsating and non-pulsating current
Inventor: SCHROEDER DIERK PROF DR ING
IPC: H02M7/757
Filed: 1982-02-25
Abstract: In converter actuators having resistive-inductive loads (e.g. the armature circuit of a DC machine) operating modes occur with a pulsating and non-pulsating load current. During the transition from one operating mode to the other, the control characteristics change suddenly, especially the dynamic gain of the converter and load circuit. Among other things, a pulse-adaptive controller has to compensate for the lower gain in the case of a pulsating load current by an increased controller gain. However, if the non-pulsating operating mode is identified too late, the load current can overshoot despite optimised control parameters. The identification method proposed here uses the converter control voltage rather than the load current or mean low current value to identify the operating mode which the actuator is in from the next current-flow period. In a first embodiment, the load circuit and converter parameters and any existing back-e.m.f. are taken into account. Furthermore, a solution is specified which uses only one comparator and the linear combination of the control voltage and the smoothed converter output voltage.
