Abstract
1,017,362. Thickness and moisture gauges. E.K. COLE Ltd. July 6,1964 [July 11, 1963], No. 27476/63. Heading G1A. A gauge for measuring such characteristics, of a web or strip of material, as thickness or moisture content, is arranged to traverse the material and has means synchronized with the traverse mechanism to vary the value of an impedance in the circuit of the gauge automatically in accordance with a predetermined programme to correct or reduce, in the output of the gauge, the effect of any mechanical imperfections in the traverse mechanism. In a thickness gauge using a radiation system, the source and detector may be mounted on the opposite sides of the material or, in the backscatter type of arrangement, on the same side as a single unit. In the arrangement of Fig. 2 the detector 1, an ionization chamber, and the source 15, move on respective rails or rods 11, 12, driven by chains 16, 17 mechanically coupled to the appropriate housings 13, 14. The chains are driven by a motor 28 which also provides the drive for the compensation unit 38, through a gear wheel 37 on shaft 36. The shaft 36 drives, through gear wheels 41-44, (Fig. 3 not shown) a disc 39 carrying a number of screws 40, so that the angular position of the disc 39 bears a constant relationship to the position of the gauge on the traverse mechanism. The screws 40 are adjusted to correspond with errors in measurements obtained at corresponding positions of the gauge along the traverse mechanism. As the disc revolves, the screws abut against a cam 48 mounted on an arm 46 which is caused to be raised or lowered, its free end being coupled through gears 50, 51 to a variable resistor 52, which forms part of the detector circuit, the value of the resistor being varied so that a true measurement is obtain in the meter (Fig. 1, not shown). The invention also has application in moisture gauges, where the plates of a capacitor are mounted either side of the material.
