| 366127000 | By electrostrictive or magnetostrictive transducer | 6 |
| 20080247264 | Apparatus and Method For Moving a Liquid by Means of a Piezoelectric Transducer - An apparatus having a device for moving a liquid comprises a piezoacoustic resonator element ( | 10-09-2008 |
| 20080316854 | Microfluid mixer - A microfluid mixer is provided. The non-linear electrokineticsis is applied to the design of the microfluid mixer. The microfluid mixer comprises a first and a second microfluidic elements, a mixing reservoir, and a micro channel unit, wherein the micro channel unit has at least two control channels for respectively connecting the first and the second microfluidic elements and the mixing reservoir. When two microfluids are mixed in the mixing reservoir, the electro-osmosis fluid field of the microfluids in the control channel of the mixing reservoir is changed by applying AC signal, such that powerful chaotic mixing effect is therefore produced by the two microfluids in the mixing reservoir. | 12-25-2008 |
| 20090034360 | METHOD FOR MICROFLUIDIC MIXING AND MIXING DEVICE - A method of mixing ( | 02-05-2009 |
| 20090129197 | METHOD AND DEVICE FOR INDUCTION STIRRING OF MOLTEN METAL - The invention relates to a method and device for the induction stirring of liquid metal in the bath of a reverberatory furnace by the action of a traveling magnetic field whose frequency ranges from 50 to 60 Hz. The inventive method consists in producing a magnetic field action on a molten metal at a height of (0.1-0.5)H from the furnace bottom, wherein H is the bath depth, and, in a horizontal direction, along the plane of a chamber ( | 05-21-2009 |
| 20100238760 | CONSTANT LOAD SHEAR CELL FOR MAGNETORHEOLOGICAL FLUIDS - The invention relates to a constant load shear cell and a method for constant loading of a magnetorheological fluid in a constant load shear cell. The constant load shear cell comprises a rotatable shaft ( | 09-23-2010 |
| 20160136598 | ULTRASONIC SYSTEM FOR MIXING MULTIPHASE MEDIA AND LIQUIDS, AND ASSOCIATED METHOD - The invention describes an ultrasonic device primarily intended for sonication of liquid and multiphase-media (gas-liquid, solid-liquid) through flexural vibration of tuned blades. The ultrasonic system comprises a source of alternating electrical field, an electro-acoustic transducer connected to the source of alternating electrical field, a booster connected to the electro-acoustic transducer with a cross section distal to the electro-acoustic transducer smaller than a cross section proximal to the electro-acoustic transducer, and at least one tuned blade coupled to the booster, wherein the at least one blade couple flexural vibrations to the liquid or multiphasic media. The system allows the treatment of larger volumes of fluid media compared with conventional longitudinally resonant ultrasonic devices characterized by small radiating surfaces. The flexural motion of the tuned blades may be achieved through the use of an electro-acoustic transducer operated in a torsional mode of vibration, or via a sub-assembly excited in a torsional-longitudinal composite mode. | 05-19-2016 |
