  • Electroacoustic delay lines
    Patent number: 4525692
    Abstract: An ultrasonic delay line fabricated from a solid transmission medium is configured to provide (2n+3) reflections of the desired signal at five reflective facets of an irregular polygon. The reflective pattern tends to allow maximum surface area available for the deposition of absorbent material so as to thereby and otherwise minimize spurious transmissions. In an alternative embodiment, a bifurcated delay line includes two branches physically coupled at one end and electrically coupled through a pair of transducers so that approximately half the height and width of transmission medium is required in order to effectuate a predetermined time delay.

  • Bifurcated electroacoustic delay lines
    Patent number: 4499439
    Abstract: A bifurcated electroacoustic delay line exhibits at least a pair of substantially identical branches, each assuming a generally pentagonal profile. Each branch is configured to provide (2n+3) reflections of a desired wave at five reflective facets. The reflective pattern so defined tends to maximize the surface area available for the deposition of absorbent material so as to thereby and otherwise minimize spurious transmissions.The branches are physically joined along at least one side and include transducers for the conversion of electrical energy to acoustical energy. An inductance connected between two such transducers couples energy from one branch to the other.

  • Bifurcated electro-acoustic delay lines having transducers bonded at an area of bifurcation
    Patent number: 4488127
    Abstract: A bifurcated electroacoustic delay line exhibits at least a pair of substantially identical branches, each assuming a generally pentagonal profile. Each branch is configured to provide (2n+3) reflections of a desired wave at five reflective facets. The reflective pattern so defined tends to maximize the surface area available for the deposition of absorbent material so as to thereby and otherwise minimize spurious transmissions.The branches are physically joined along one side so as to define an area of bifurcation. A plurality of piezoelectric transducers are bonded at the area of bifurcation in a pairwise laterally adjacent manner. An inductance couples electrical energy from the output transducer of the first branch to the input transducer of the second branch.
