Apparatus for processing materials by ultrasonic waves oscillation
Use of the odd harmonics of a piezoelectric radiator in an ultrasonic interferometer for liquids Ilgunes, V., Paulauskas, K., Tamashauskas,A. Soviet Physics-Acoustics, Vol 16, No 1 (JulySeptember 19’70) pp 122-123 Contactless vlbrometer for measurement of the displacement amplitudes in ultrasonic vibratory systems Kitaigorodskii, Yu. I., Stamov-Vitkovskii, A. V. Soviet Physics-Acoustics, Vol 16, No 1 (JulySeptember 1970) pp 126-128 Ultrasonic semiconductor transducers with an exponential conductivity-thickness distribution Nevskii, Yu. E. Soviet Physics-Acoustics, Vol 16, No 1 (JulySeptember 1970) pp 135-136 Electroacoustical transducer Massa, F. (Massa Division, Dynamics Corp of America) US Patent 3,510,698 (1970) An ultrasonic transducer comprises a massive cylinder and a piezoelectric disk which is attached with one flat side to the metal cylinder. The other side Contains a central electrode and an annular electrode which are excited by two conductors. The disk deforms responsive to such excitation. Apparatus for processing materials by ultrasonic waves oscillation Takashi Hatukano US Patent 3,487,582 (1970) An ultrasonically oscillating rotary drilling tool for drilling or polishing gems and including a grinding wheel positioned so that the tool can be sharpened by moving the drill for contact with the grinding wheel. Cleaning method and apparatus Veith, R. D. (Soniflow Equipment Co) US Patent 3,499,792 (1970) Apparatus for cleaning the surface of an article comprises a length of tubing having orifices spaced along its length and means for forcing liquid under pressure into the tubing to produce jets of liquid emanating from the orifices. Ultrasonic energy is introduced into the liquid in the tubing so that a wave of ultrasound is transmitted through the liquid and produces cavitation in the jet streams emanating from the orifices. Method and apparatus for the production of sonic or ultrasonic waves on a surface Hellmut Schneider US Patent 3,503,804 (1970) This patent refers to an ultrasonic cleaning device wherein a laser beam is transmitted to a surface to be cleaned, concurrently with a liquid jet providing ultrasonic vibrations. Ultrasonic bonding method Coucoulas, A. (Western Electric US Patent 3,507,033 (1970)

During ultrasonic welding of copper or aluminium leads to substrates, heating current is supplied to the jolnt via two wire conductors and the lead wire to be welded to the substrate. The temperature is increased above the re-crystallisation point.
Method and apparatus for detecting leaks Palmer, M. N. (Gulf Research and Development Co) US Patent 3,500,676 (1970) The instrument detects leaks in the sonic and ultrasonic range, and is used primarily with pressurised fluid systems. A tuneable amplifier is used so that steady leakage sounds can be distinguished from other extraneous noises, and a frequency divider converts ultrasonic vibrations to the audible range. Ultrasonic testing apparatus Hetherington, M. J. (Stewarts and Lloyds Ltd) US Patent 3,501,947 (1970) A pulse-echo transducer for testing a tubular object is adapted for coupling to the test object by jets of water, and rotates by being attached to the body relative to the inner sleeve. A water bearing permits the tubular body to rotate. Pipeline leak detector Bustin, W. M. (Esso Research US Patent 3,508,433 (1970)

Ultrasonic net weight load indicator for vehicles Greenstein, E. (Earl C. Nolan) US Patent 3,508,623 (1970) Ultrasonic thickness measuring apparatus Moore, C. C. (American Machine & Foundry Co) US Patent 3,509,752 (1970) Underwater transducer Bozich, D. J. (Wyle Laboratories) US Patent 3,500,304 (1970) A cylindrical transducer made up of sixty I-beams whose outer flanges notch to provide interlock between adjacent I-beams. A surrounding rubber boot makes the assembly watertight. Lead zirconate ceramic blocks are bonded to the webs of the Ibeams. The transducer has a frequency range of 1OOHzto 1OkHz. Method and apparatus for treatment of organic structures with ultrasonic energy Balamuth, L. (Ultrasonic Systems Inc) US Patent 3,499,437 (1970) Plane ultrasonic transducer diffraction fields in highly anisotropic crystals Kharusi, M. S., Farnell, G. W. Journal of Acoustical Society of America, Vol 48, No 3, Part 2 (September 1970) pp 665-670 Resonance curves of gas bubbles ln liquids Lauterborn, W.
