20090086569 | Amplitude change-over device for a body vibration machine - An amplitude change-over device for a body vibration machine includes two eccentric units respectively fixed on the opposite ends of a rotating shaft driven by a motor. Each eccentric unit contains an eccentric driving plate secured with the rotating shaft for rotating together and an eccentric driven plate movably fitted on the rotating shaft at one side of the driving plate. Either one of the driving plate or the driven plate has a surface bored with a slide groove with the rotating shaft acting as a pivot, and another one has a surface provided with a projecting stud inserted in the slide groove. The motor is a right-handed and left-handed one. When the motor is chosen to rotate clockwise or counterclockwise, the included angle of the driving plate and the driven plate is changeable and hence amplitude power is adjustable by using a single motor. | 04-02-2009 |

20140269151 | EMAT ENHANCED DISPERSION OF PARTICLES IN LIQUID - Particulate matter is dispersed in a fluid material. A sample including a first material in a fluid state and second material comprising particulate matter are placed into a chamber. The second material is spatially dispersed in the first material utilizing EMAT force. The dispersion process continues until spatial distribution of the second material enables the sample to meet a specified criterion. The chamber and/or the sample is electrically conductive.

The EMAT force is coupled to the sample without physical contact to the sample or to the chamber, by another physical object. Batch and continuous processing are utilized. The chamber may be folded within the bore of the magnet. Acoustic force frequency and/or temperature may be controlled. | 09-18-2014 |
