Abstract

946,708. Electromechanical delay lines. A. C. COSSOR Ltd. June 28, 1962 [June 28, 1961], No. 23437/61. Heading H3U. A variable ultrasonic delay line of the type using multiple reflection within a faceted body of e.g. quartz, comprises also a second body which is slidable upon a facet of the first body and provides a variable portion of the wave path. As shown, the first body 10 has the general shape of a truncated wedge of small angle, the angle being such that a wave from input transducer 18 travels from the L.H. to the R.H. end of the wedge and then vice versa as it suffers multiple reflection between major facets 11, 12. From the L.H. end it is reflected by facet 15 towards the opposite end facet 13 upon which the second body 21 is slidable. The wave enters the second body and is reflected by facet 23 towards the L.H. end of the first body where it is received by transducer 24. The path length within body 21 depends upon its position; two different paths D, E for two alternative positions of the body 21 are indicated. The two bodies are pressed close to each other with a thin layer of a viscous medium between. The medium preferably has inverse-thixotropic properties. Poly-isobutylene may be used.
