20110290918 | PROCESS FOR EFFICIENT MILLING OF PARTICLES TO A PREDETERMINED PARTICLE SIZE AND/OR PARTICLE SIZE DISTRIBUTION - The present invention is a process for efficiently milling particles to a predetermined particle size and/or particle size distribution. The process includes feeding a fluid dispersion containing particles to be milled into a chamber. The process also includes contacting a fiber milling assembly in said chamber with said particles. Further, the process includes milling said particles for less than or equal to 40 minutes. | 12-01-2011 |
20110290922 | FIBER BASED MILLING DEVICE AND METHOD - The present invention describes a fiber based milling device for milling particles. The fiber based milling device includes a milling chamber with an inlet and an outlet, and also at least one fiber assembly. The fiber assembly contacts a particle to be milled in the milling chamber. Also disclosed is a method for milling particles by contacting the particles to be milled with a fiber assembly. | 12-01-2011 |

Cincinnati OH US - The present invention provides a reversible piezochromic system that changes appearance upon application of a mechanical force. The reversible piezochromic system includes a cavity defined by a first substrate and a second substrate. The cavity includes at least a first fluid. The first fluid spreads when a mechanical force is applied to the system. The relaxation time of the first fluid depends upon the internal forces of the system. These internal forces at least include the surface energy differences between the substrates and the fluid or fluids, and the rheological properties of the fluid or fluids. | 01-17-2013 |
