Abstract
867,858. Measuring electrically. AVERY Ltd., W. & T. Oct. 18, 1957, No. 32541/57. Class 40 (1). A pick-up device for use in a rotor balancing machine comprises a resilient member 1, Fig. 5, connected between the machine bed 9 and a rigid mass 7, one or more strips of piezo-electric material being fixed to the member 1. The piezo-electric strip 2, Fig. 1, is conductively coated on each face and is glued to a portion 1a of the member of reduced cross-section, the output from the strip being amplified by means not shown. Two strips may be fixed to each side of the portion la and so connected as to compensate bending moments. Fig. 3 shows the member 1 as a solid or hollow cylinder having a plurality of strips uniformly arranged on its outer periphery with the longest axes of the strips parallel to the axis of the member; alternatively, they are at right-angles to it.
