Abstract

1433296 Fluid-pressure apparatus O & K ORENSTEIN & KOPPEL AG 15 March 1974 [17 March 1973] 11690/74 Heading F1P A device for producing a fluid-pressure wave when loaded comprises a tread-plate 5, Fig. 1, which, when loaded, flexes and compresses the unsupported upper portions of a tube 4 arranged in grooves in a base member 2. The tube 4 is laid in a sinuous path, Fig. 3. Fig. 4 shows an embodiment in which the tube is completely embedded, the layer of material 14 above the tube 13 being thinner than the rest, so that the upper part of the tube buckles inwards when loaded. The pressure wave may operate a switch.
