[Also in Division H4] An electric signal generator comprises, a conductor having a straight section and a coplanar section spaced from the straight section by distances representing a desired relationship between two parameters, an apparatus establishing a flux through the conductor and movable with respect to the conductor and a signal output means connected to the conductor. As shown, a narrow elongated line of magnetic flux is established, in a gap 11C between polepieces 11A, 11B of a magnetic core 11, by an alternating current flowing through windings 12, 13 which is supplied from a generator 14. Through the gap 11C passes a non-conductive plastic card 20 on which is disposed looped conductors disposed in patterns corresponding to desired relationships between parameters, such as temperature and time. Each loop comprises a straight base position 21A, 22A and a shaped portion 21, 22. The conductor is a small diameter enamelled copper wire, glued or taped to the card, or a printed circuit. The induced voltages in the looped conductors are fed by twisted pairs 23, 24 to AC/DC converters 25, 26 connected to programme utilization devices 27, 28. The generator 14 is controlled by a reference loop, having a pair of parallel edges 31, 31A, connected through a twisted pair to an AC/DC converter 33, the output of which is compared with a D.C. reference signal from a source 34 by a detector 16. The detector 16 controls an amplifier 17, in the supply from an oscillator 15 to the windings 12, 13, so as to maintain constant the induced voltage in the reference loop. The core 11 is traversed along the card 20 by a worm and nut arrangement 38, 41 driven by an electric motor 39. In an alternative arrangement the flat card is replaced by a right circular cylinder around the surface of which the core 11 is rotated. The core 11, is made from thin laminations mounted in an aluminium frame disposed within a copper container. |
