Abstract

1,083,531. Electromechanical delay lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 14, 1966 [April 17, 1965], No. 16419/66. Heading H3U. A delay line comprises a prismatic body L of e.g. pressed glass having an input face 4 provided with a piezoelectric input transducer T 1 , an output face 5 of 90 degrees to the face 4 and provided with a piezoelectric output transducer T 2 , a reflecting face 3 at 45 degrees to the faces 4, 5, and parallel reflecting faces 1, 2 at 90 degrees to the face 3. The length of the faces 1, 2 is twice that of the face 3 so that each vibration transmitted by T 1 is reflected twice on each of the faces 1, 2 before arriving at T 2 . This double reflection cancels out any error which would otherwise be present due to a slight manufacturing misalignment of the faces 1, 2.
