Abstract: 798,397. Position indicating means. BRITISH THOMSON-HOUSTON CO., Ltd. July 5, 1956 [July 5, 1955], No. 19422/55. Class 40 (1). A means for measuring the relative positions of two objects comprises a helical magnetic band 4 on a rotatable member 1 axially fixed in relation to one of the objects and co-operable with a magnetic bridge piece 5 movable with the other object in directions indicated by 3. At least one end of the bridge piece 6 is narrow compared with the width of 4. The helical band is energized by means of a D.C. or very low frequency excitation coil 7 or otherwise and a square wave is produced in the output coil 8 as the rotatable member revolves relatively quickly. The phase of the output (which may if desired be taken from the excitation coil 7) is indicative of the position of the bridge member. The bridge member should span an integral number of threads. Provisions are described for having two bridge members either separate or combined to form a single E-shaped piece as in Fig. 2. The width of the band 4 is preferably equal to the space between the bands, which should be filled with material of high reluctance. This material may be air. The band 4 may be a magnetic tape wound on a non-magnetic cylinder. Means are described for rotating the bridge member about 1 automatically as it moves along the length of 1 by means of a cam and in such a manner as to overcome systematic errors in the construction of the helix. The output signal may be used in a servo system to keep the relative positions of the objects constant. Specification 766,656 is referred to.
