Patent EP-0028794-A1 (EP)
Inventor: GOEDECKE LUDGER DIPL-ING
IPC: G05B9/02
Filed: 1980-11-03
Abstract: A heating arrangement in a fixing station of a printing device has its operation monitored by an arrangement in which a measuring element is disposed in series with the heating element and a switch element. The measuring element is traversed by the heating current and emits a corresponding voltage which is supplied to an amplifier circuit which produces pulse-shaped clock signals as long as the heating current flows through the measuring element and the heating element. The clock signals are supplied to a reset input of a flip-flop whose dynamic input is connected to an oscillator operating at a frequency lower than that of the alternating current so that as long as clock pulses occur, the flip-flop is constantly reset. Therefore, the flip-flop can only be set over a longer interval when no heating current is flowing. If heating current flows although no heating current should flow, the same is identified by a counter whose counting input is connected to the amplifier circuit and whose reset input is connected to a heat sensor. Therefore, an undesired heating current through the heating element causes operation of the counter. A set flip-flop or a counting counter indicate malfunctions of the heating arrangement.

Abstract: The active parts of such units are normally prepared by drying and subsequent impregnation with an insulating fluid. According to the invention, the insulating parts built into this arrangement are now produced from two different insulating materials (A and B), one of these insulating materials (A) shrinking relatively strongly on drying and the other insulating material (B) swelling so much on impregnation with an insulating fluid that it more than compensates for the shrinkage of both insulating materials (A and B) on drying. Such arrangements can be used in a most advantageous manner, particularly in the construction of large transformers. <IMAGE>
