Abstract

1378121 Delay lines TESLA NARODNI PODNIK 22 Feb 1973 [16 March 1972] 8860/73 Heading H3U In an electroacoustic delay line comprising a glass, fused or crystalline quartz, ceramic, or crystalline KCl delay medium 1 supporting input and output transducers 2, 3, holes 4 are provided to attenuate the dispersed side lobes of the acoustic wave propagated between the transducers. The holes, which can be partly or fully filled with an epoxy resin-kaolin mixture have a depth of at least <SP>2</SP>/ 3 the medium thickness, and may be through holes. They are moulded, drilled, or ultrasonically formed, may be of square, parallelogram or trapezium cross-sectional shape, and may have bevelled edges. The medium has indentations 6, 7 and chamfers 5, and may be provided with attenuation linings (not shown). The delay line is used in colour TV equipment, decoders, or digital computers.
