Abstract

857,464. Position-measuring devices. KOLLSMAN INSTRUMENT CORPORATION. April 4, 1957 [Nov. 7, 1956], No. 11013/57. Class 40 (1). [Also in Groups XXXV, XXXIX and XL (c)] The position of a body is expressed in terms of a frequency by varying the cross-sectional area of the magnetic core of a transductor, thereby altering the value of current in the control windings at which the core saturates; the current is switched between two control windings so that the frequency of switching depends on the saturation flux value. In Fig. 1, the transistors 26 and 28 form a multivibrator passing current alternately through the windings 14 and 16 to saturate the core 12 alternately in the two directions, 18 and 20 being the feed-back windings which switch the circuit from one state to the other. The circuit is normally self-starting but if necessary a priming pulse can be injected at 33. The output is taken from winding 22. The core 12 is in the form of a ribbon (Fig. 3) wound together with the windings over a high-permeability fixed core 34, which is energized by a D.C. winding 36 or (not shown) a permanent magnet. The body whose position is to be measured is attached to a rod 40 whose axial position determines the coupling between cores 12 and 34 via the movable core 35. By suitable shaping of the cores 34 and 35 (Figs. 6 and 7, not shown), any desired law can be produced between the linear movement of the rod 40 and the output frequency. The transistors can be replaced by valves.
