摘要： An acoustic apparatus comprises an inner cabinet, a vibrator mounted thereon and an outer cabinet. The inner cabinet and the outer cabinet constitute an acoustic cabinet having a closed cavity. The outer cabinet covers the inner cabinet with a predetermined gap formed between the inner peripheral surface of the outer cabinet and the outer peripheral surface of the inner cabinet and has an opening causing the gap to communicate with the external region of the acoustic cabinet and to function as a resonance port. The resonance port and the closed cavity constitute a resonator. The vibrator is provided so as to face the closed cavity. The resonator radiates a resonant sound from the open end of the gap, i.e., the resonance port, upon being driven by the vibrator.

摘要： A side-scanning sonar towfish constructed from a solid polyvinyl chloride (PVC) rod is provided. The PVC rod is milled and slotted to provide recesses for electronics and transducers and slotted to provide attachment points for fins and tow rail. The entire fish is then filled and sealed with urethane thereby providing sealed solid unit. A special multi-layer acoustic matching system is bonded over the transducers to provide maximum coupling efficiency of the acoustic signal thereby allowing operation of the fish at reduced power requirements.

摘要： An ultrasound system, employable for medical imaging, includes an electronics module and a probe. The probe includes a body, a transducer, a driver, a window and coupling fluid. The electronics module includes a transmitter which generates transmission pulses which are converted by the transducer to ultrasound pulses and a receiver which analyzes electrical signals resulting from the conversion of ultrasonic reflections received by the transducer. The electronics module controls delays in the transmission and reception between individual elements of the annular phased array transducer to control focussing. The driver provides for mechanical steering of the transducer. The coupling fluid provides for ultrasonic coupling between the transducer and the window and the subject while permitting the steering movement of the transducer. The coupling fluid is a mixture of 1-Butanol in Glycerol. The attenuation of that mixture can be adjusted without impairing velocity matching by adding suitable amounts of 2-Hydroxyethyl ether.

摘要： A shock wave generator for use in an extracorporeal lithotripsy apparatus has a liquid-filled housing with an exit aperture for shock waves which are electromagnetically generated and conducted to a focusing element for focusing onto the calculi, and a plate-shaped element having a smaller cross-sectional area than the emitted shock wave is disposed in the path propagation of the shock wave. The plate-shaped element consists of a material having an acoustic impedance substantially corresponding to the acoustic impedance of the liquid in the housing, and having a propagation speed of sound therein which deviates from the propagation speed of sound in the liquid.

摘要： A couplant material for establishing a sonic path of good acoustical impedance between an ultrasonic transducer and a sonic medium. The material is capable of being easily shaped at room temperature and withstanding vibration and thermal cycling from room temperature to over 500.degree. F. while substantially maintaining its acoustical properties and providing a minimum of irritating fumes and outgasses. A preferred couplant material is a polytetrafluoroethylene grease or perfluoropolyalkylether grease, which have been used previously as lubricants.

摘要： Disclosed is an acoustic horn to aid in bulk powdered material handling particularly from trucks and railroad cars. Such acoustic horn is comprised of an external cone having a driver affix thereto. There is also an inverted internal cone contained within the external cone. There is a cylindrical throat communicating with the acoustic wave driver which extends into the internal cone, the combination of the throat extending into the internal cone contained within the external cone creates a folded horn arrangement wherein a horn of relative shortened length can achieve the desired low fundamental frequencies needed for bulk powdered material handling.Extending radially from the mouth of the external cone is a flange. Means are provided to detachably affix said flange from the flange on existing manways present on trucks and railroad cars.
