Abstract:
An ultrasonic mixing system having a treatment chamber in which at least two separate phases can be mixed to prepare an emulsion is disclosed. The treatment chamber has an elongate housing through which the phases flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the phases within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other.
Abstract:
A method of preparing metal-modified silica particles is disclosed. Specifically, a treatment chamber is provided in which a first and a second formulation are ultrasonically mixed to prepare metal-modified silica particles. The treatment chamber has an elongate housing through which the first and second formulations flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulations within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the formulations being mixed in the chamber.

Abstract:
The present invention provides a device able to induce a pressure and flow rate oscillation in a liquid stream that flows inside a pipe. The said stream is fed through an inlet (2) into a chamber (1) comprising one or more sound emitting devices (4) with a frequency and amplitude set by one or more electrodynamical sound sources (6), imposing an oscillation of one or more diaphragms (5) in order to produce a pulsed flow at one or more chamber outlets (3), allowing the incorporation of measuring instruments (7) to monitor the vibration characteristics of the outlet (3). The pulsed stream can be used as feeding stream in micro reactors, precipitators, static mixers, cutting jets, erosion and polishing jets, combustion or explosion chambers, and units for emulsification.

Abstract:
The present invention relates to an ultrasound liquid atomization and/or separation system comprising an ultrasound atomizer and a liquid storage area in communication with said ultrasound atomizer. The system may further comprise an injector containing an injector body housing the ultrasound atomizer and a channel or plurality of channels running through said injector body and delivering liquids to said ultrasound atomizer. The ultrasound atomizer comprises an ultrasound transducer, an ultrasound tip at the distal end of said transducer, a liquid delivery collar, a liquid delivery orifice or plurality liquid delivery orifices, and a radiation surface at the distal end of said tip. The liquid delivery collar may further comprise a central orifice into which said ultrasound tip may be inserted. Ejecting and atomizing liquid in a pressure independent manner, the liquid atomization and/or separation system of the present invention enables the production and release of a consistent spray of liquid into an environment despite changes in pressure within the environment. Mixing liquids during injection and atomization, the system of the present invention also enables the production of hybrid liquid sprays. Atomizing liquids enables the separation of liquids from gasses, liquids, solids, or any combination thereof suspended and/or dissolved within said liquid.

Solid formulations for use in water conditioning of circulating reservoirs, processes of preparing same and methods for water conditioning utilizing same are disclosed. The solid formulations combine a sanitizer with a bath salt and/or an odoriferous substance.
Abstract:
A device and method for sono-chemical processing of at least one liquid, the device including: (a) a reaction volume, at least partly defined by a substantially cylindrical wall, for containing the liquid; (b) a first magnetostrictor for producing a first series of ultrasonic waves having a first frequency; the wall and the first magnetostrictor designed such that with the liquid disposed within the reaction volume, the first series of ultrasonic waves radiates radially inward into the volume, thereby producing a volume of concentrated cavitation along a longitudinal axis of the reaction volume; (c) a second magnetostrictor for producing a second series of ultrasonic waves having a second frequency, the second frequency exceeding the first frequency, and (d) a wave guide, associated with the second magnetostrictor, disposed adjacent to a surface of the reaction volume, for directing the second series of ultrasonic waves into the reaction volume.
Abstract:
Es werden Verfahren und Vorrichtungen zur Herstellung von hochfeinen Partikeln beschrieben, die anschließend in einem weiteren Prozessschritt mit schützenden Polymeren überzogen werden. Dabei werden die Partikel mittels eines Verfahrens hergestellt, bei dem ein Flüssigkeitsstrom aus einer partikelfreien, den Wirkstoff gelöst enthaltende Flüssigkeit 1, mit einem zweiten Flüssigkeitsstrom aus einer Flüssigkeit 2 in einer hochenergetischen Zone oder frühestens 2 Sekunden vor Erreichen der hochenergetischen Zone zusammengeführt wird, wobei die beiden Flüssigkeiten miteinander mischbar sind und der in der Flüssigkeit 1 gelöste Wirkstoff nicht oder geringer in der Flüssigkeit 2 löslich ist und in der oder innerhalb von maximal 2 Sekunden vor Erreichen der hochenergetischen Zone beim Vermischen der beiden Flüssigkeiten als Partikel ausfällt. Die so hergestellten Partikel werden in eine wässrige äußere Phase, die die Beschichtungs- bzw. Überzugsmaterialien in gelöster Form enthält, eingebracht, und anschließend einem Trocknungsschritt unterzogen, wodurch diese Materialien als geschlossene Beschichtung auf den Partikeln ausfallen. Die so umhüllten Partikel sind vor schädigenden Einflüssen geschützt und weisen im Gegensatz zu nicht umhüllten Partikeln eine modifizierte Freisetzungskinetik auf .
Abstract:
A treatment system including a vibratory mixer is disclosed. The vibratory mixer comprises a vibrating element to facilitate the dissolution of a treating agent that facilitates separation of solids from liquids in water and wastewater streams. Vibratory mixing energy that effects mixing is generated by utilizing magnetostrictive or piezoelectric materials.
