A Hall plate of the type claimed in the parent Specification is used to detect movement of a track having areas whose magnetic properties alternate between two discrete types. As shown in Fig. 1 the track is circular, four or more such tracks 3, 4, 5, 6 being used to represent the rotation of the disc 1 in binary form. In one embodiment, Fig. 2, the successive areas are either magnetized in opposite directions, or magnetized and unmagnetized. The tracks 3 . . . 6 lie adjacent to Hall plates 13 ... 16 which thus produce corresponding outputs as the disc rotates. In modifications, Figs. 3, 4 (not shown), the tracks contain alternate magnetic and non-magnetic areas, the tracks completing a magnetic circuit containing the Hall plates, the flux for this circuit being provided either by a permanent or an electromagnet. Where the size of the track is small compared with the size of the Hall plate 15, Fig. 5, the latter may be provided with a polepiece 24 taped towards the track. In the case of there being a plurality of tracks and Hall plates, these are angularly staggered. In an alternative embodiment a flux path having two gaps is provided, one gap containing the Hall plate and the other the track. The relative displacement can instead be obtained by counting pulses derived from such an arrangement, the track consisting of a succession of equal areas whose magnetic properties alternate. The Hall plates may be provided with an A.C. input whereby there is obtained an A.C. output whose amplitude is varied in accordance with the magnetic properties of the track.

Class 65(1) In a door closer of the type having a spring chamber 2, a fluid-check chamber 3, and a radial actuating arm 34, wherein a spindle 9 connecting the arm to the fluid check extends axially through the spring chamber and cairries a rotatable sleeve 13 having two annular members 14, 15 rotat-. ably mounted thereon and anchored to opposite ends of the spring 31, the arm 34 has a hub 33 which is detaehably and non- rotatably secured to the end 10 of the spindle and has a recess 35 provided with a system of internal dog teeth 40 which mesh with the teeth of a wheel 38 detachably and non-rotatably mounted on the sleeve 13. The members 14, 15 each have two projecting stops one of which engages a corresponding stop on the sleeve and the other a stop formed on the casing of the spring chamber, the stops being so arranged that rotation of the arm 34 in either direction causes one of the members to remain fixed relative to the chamber while the other rotates with the sleeve in the spring- winding direction. The dogs project inwardly from the wall of the recess, and their thickness, and that of the wheel 38, is less than the depth of the non-circular hole 36 provided in the hub to engage the spindle, so that on loosening the securing nut 41 and raising the hub sufficiently to disengage the teeth, the arm and the spindle remain in engagement. The tension of the spring cam then be increased by rotating the arm 34, re-engaging the teeth, and returning the arm to its original position.
