Abstract

770,550. Testing laminates. ROE & CO., Ltd., A. V. Aug. 5, 1955 [Aug. 23, 1954], No. 24438/54. Class 140. Lack of adhesion of the skin of a honeycomb sandwich panel p is detected by causing it to produce an upward movement of a pressurebiased rod f when the skin is lifted by a vacuum formed in a space i bounded by the skin p, the lower surface of a casing b in which the rod is slidably mounted, and a pliable skirt a attached to the casing. The space i is evacuated momentarily through a pipe h. Movements of a strain gauge transducer loop k attached to the rod are used to cause meters or indicators such as coloured lamps to give a reading or signal.
