Abstract

1,111,134. Measuring strain electrically. ENDEVCO CORPORATION. April 30, 1965 [May 4, 1964], No. 54418/65. Divided out of 1,111,133. Heading G1N. The description is wholly included in the Specification of the parent Specification 1, 111, 133, but the claims are directed to the use of a semiconductor strain gauge to detect relative displacement of two rigid members interconnected by a hinge. In particular, the hinge may be a Cardan hinge; and a beam with a portion of locally reduced cross-section - e. g. with a transversely grooved central portion - can be regarded as two rigid members (the beam ends) joined by a Cardan hinge (the reduced cross-section central portion). Such an arrangement is exhibited in the accelerometer shown in Fig. 3, in which two strain gauges 8 are mounted on a beam 44 with the ends 12 of the gauges bonded to respective ends of the beam and with the central sensitive portion 10 of each gauge unbonded to the beam and spanning a transverse groove 48 between the beam ends.
