Abstract

687,373. Accelerometers. SOC. D'ELECTRICITE MORS. Aug. 16, 1950 [Aug. 24, 1949], No. 20320/50. Class 106 (iii). A shock indicating device comprises resilient means 3 gripping at least two bodies 1 of appreciable weight, the gripping means being so arranged that if the device is accelerated in any direction at a rate above a predetermined value, at least one of the bodies is released. The weights may be balls 1 gripped between pairs of resilient fingers 3. If necessary, the gripping effect of these fingers may be independently adjustable in any known manner. The shock indicating device may be housed behind a transparent closure in the wall of a package.
