Abstract

1,171,261. Ultrasonic delay lines. MULLARD Ltd. 24 Oct., 1968 [16 Feb., 1968], No. 7759/68. Heading H3U. A solid body forming a multi path acoustic delay line is characterized by at least one internal reflecting surface for the acoustic wave formed by the wall of a slit extending inwards from an edge face of the body. In the embodiment of Fig. 2, there are two slits 2, 4 in the solid body 1, the input and output piezo-electric transducers being denoted by A and B, the wave path between the transducers being denoted by the broken lines. The number of reflecting legs between the two side walls of slit 2 or 4 is an odd number whereby the accuracy of angles 5 and 6 is not critical due to the cancelling-out effect. In other embodiments (Figs. 1, 3 and 5, not shown) there is a single reflecting slit. In another embodiment (Fig. 4, not shown) there are four slits and only one side wall of each slit serves as a reflecting surface.
