摘要： A sonicator apparatus having a signal generator for generating high frequency sound waves to a convertor which transforms electrical energy into mechanical energy in the form of oscillations to a horn having a probe immersed in a sample disposed in a sample holder includes a shielding arrangement having one end sealed against the convertor and another end sealed against the sample container and defining an aerosol containment chamber for preventing aerosols generated by oscillation of the probe in the sample from becoming airborne. The apparatus further includes a self centering device to insure proper disposition of the probe relative to the sample holder and use of a partial vacuum to provide a more efficient evacuation of aerosols from the chamber and simultaneously diminish noise levels. An enclosure provided with sound absorbing foam enhances the reduction of noise.

摘要： This invention relates to a continuous ultrasonic method for breaking the carbon-sulfur (C--S), sulfur-sulfur (S--S), and if desired, carbon-carbon (C--C) bonds in a vulcanized elastomer. It is well known that vulcanized elastomers having a three-dimensional chemical network, cannot flow under the effect of heat and/or pressure. This creates a huge problem in the recycling of used tires and other elastomeric products. Through the application of certain levels of ultrasonic amplitudes in the presence of pressure and optionally heat, the three-dimensional network of vulcanized elastomer can be broken down. As a most desirable consequence, ultrasonically treated cured rubber becomes soft, thereby enabling this material to be reprocessed and shaped in a manner similar to that employed with uncured elastomers.

摘要： The invention is a sampling device (4) and method used to remove bubble free samples from a bubble laden liquid. The device includes a power supply (10), a transducer (6) and a sampling probe (5). The power supply (10) converts normal line voltage to 20 kHz electrical energy. This high frequency electrical energy is converted to mechanical vibrations via the piezoelectric transducer (6). These mechanical vibrations propagate down the sampling probe (5) and emanate from the tip of the probe in the form of ultrasonic waves. The ultrasonic waves emanating from the probe tip serve to push away air bubbles from the vicinity of the tip. This allows the removal of a bubble free sample from the bubble laden liquid for further analysis.

摘要： In conventional spraying methods the problem in the preparation of small carrier particles aimed for the polymerization is that the drops constituting the prestages of the particles agglomerate or form otherwise in different sizes, whereby the size distribution of the carrier particles becomes too broad. This leads due to the so-called replica phenomenon to a polymer product having also a too broad particle size distribution. In the present invention the carrier is prepared by spraying a liquid containing a carrier through a nozzle into inert gas so that its first forms small droplets, which then solidify to small carrier particles. The desired narrow particle size distribution is provided by feeding a liquid containing a carrier through a nozzle, in which or in connection with which the liquid drops by means of the standing sonic waves in the ultrasonic range into small droplets of uniform size. The droplets of uniform size solidify then into small carrier particles of equally uniform size.

摘要： A method for separating particles from a flowing fluid suspension comprises the steps of providing an elongated chamber having closed first and second ends, flowing into the elongated chamber a fluid medium in which particles to be separated are suspended, and propagating an acoustic wave through the flowing fluid medium in the chamber. The acoustic wave is directed generally along the length of the chamber and is varied in frequency within a desired frequency range including a frequency resonant to the chamber to produce stationary coincidence excitations that separate particles from the fluid medium and urges the separated particles toward the second end of the chamber. The method also includes the steps of removing the fluid medium from the first end of the chamber and removing from the chamber the particles urged toward the second end of the chamber. The apparatus for separating particles from a flowing fluid comprises a tube having first and second open ends, a first outlet port adjacent the first end, a second outlet port adjacent the second end, and an inlet port intermediate the first and second end. Each end of the tube is closed by a spacer bonded to the tube end. A transducer is bonded to each spacer.

摘要： Methods and apparatus for controlling the movement of materials having different physical properties when one of the materials is a fluid. The invention does not rely on flocculation, sedimentation, centrifugation, the buoyancy of the materials, or any other gravity dependent characteristic, in order to achieve its desired results. The methods of the present invention provide that a first acoustic wave is propagated through a vessel containing the materials. A second acoustic wave, at a frequency different than the first acoustic wave, is also propagated through the vessel so that the two acoustic waves are superimposed upon each other. The superimposition of the two waves creates a beat frequency wave. The beat frequency wave comprises pressure gradients dividing regions of maximum and minimum pressure. The pressure gradients and the regions of maximum and minimum pressure move through space and time at a group velocity. The moving pressure gradients and regions of maximum and minimum pressure act upon the materials so as to move one of the materials towards a predetermined location in the vessel. The present invention provides that the materials may be controllably moved toward a location, aggregated at a particular location, or physically separated from each other.

摘要： A novel method for the production of bis(arene) technetium radiodiagnostic imaging agents is herein disclosed. The method consists of employing Fischer synthesis reactants in an ultrasonic bath. The products are virtually pure, thus lacking the severe degree of disproportionation which routinely occurs when partially alkylated bis(arene)technetium compounds are produced by thermally driven reactions.
