    Abstract: An improvement in electronic dimensional sensors using feelers, comprises means for automatically adding to or subtracting from the micro-indicator display of the sensor a pre-set feeler displacement value corresponding to a chosen measuring force, thus avoiding the need to take unavoidable feeler displacements into account when calculating the measured dimension. To be able to measure in both directions with the sensor there is further provided with a device for detecting the sign of the measurement in order to decide in which terms the value measured has to be modified before being displayed.

    Abstract: 933,013. Electric selective signalling systems. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Feb. 24, 1960 [March 6, 1959], No. 6449/60. Class 40 (1). In a device for converting a physical displacement into corresponding electric signals the tracks of a coded scale are scanned transversely and a pulse is produced each time a " mark " is passed. As described, resiliently mounted photo-electric cells are oscillated across the tracks of a coded scale. The coded scale, Fig. 8, comprises three concentric groups 6, 7, 8, each of nine tracks. The first group of tracks 6 (the hundreds) are marked, as shown, so that each of the ten segments into which the disc is divided contain a different number of marks and thus radial scanning of this group of tracks will produce a group of pulses corresponding in number to the particular sector scanned. The second 7 and third 8 groups of tracks are similarly marked to give units and tens respectively. Each group of tracks is scanned by a single photo-electric cell 20, Fig. 2, the three cells being mounted side-by-side on a resiliently mounted member 18. This member 18 is caused to oscillate by a coil 21 carrying 50 c/s. mains current and a permanent magnet 22, and is so constrained by stops that each cell only scans its associated group of tracks. Two methods of preventing ambiguity errors are described. In the first the scale is resiliently coupled to the shaft and is caused to progress step-by-step by teeth on its rim which cooperate magnetically with a fixed toothed permanent magnet and in the second an additional track on the scale is used to control the position of a scanning slot.
