Abstract

1327443 Magneto-sensitive resistor switching circuits GEHAP GES FUR HANDEL UND PATENTVERWERTUNG mbH & CO KG 7 Aug 1970 [8 Oct 1969 21 Oct 1969 9 June 1970] 47629/70 Addition to 1267951 Heading H3T [Also in Division H1] A contactless relay comprises a magnetic field sensitive resistor located inside a coil carrying a control current, the resistor being connected across the input of a two stage common emitter amplifier. As shown in Fig. 10 the resistor 4 is located in the control coil 1 and connected to a transistor logic circuit. In Fig. 1 two magnetic field sensitive resistors 4, 5 separated by insulation 10 are located between ferromagnetic plates inside coil 1. A similar plate may replace layer 10 (Fig. 2, not shown). Further resistors may be arranged in a stack and/or side by side (Figs. 3-5, not shown). The resistors may be let into the ends of the plates (Figs. 6 and 7, not shown). In Fig. 11 (not shown) the resistor is arranged at an angle to the length of the coil.
