20100290041 | Monolithic Optical Flow Cells and Method of Manufacture - An improved optical flow cell adapted for use in a flow cytometer for differentiating formed bodies (e.g., blood cells). Manufactured from a monolithic transparent material, the improved flow cell has an internal flow channel of polygonal transverse cross-section through which prepared samples can be metered and an external envelope suited to acquisition of optical parameters from formed bodies in such samples. Preferably, such flow cell is formed by a glass-drawing process in which a relatively large glass preform having a rectilinear internal channel of a desired polygonal cross-sectional shape is heated and drawn to achieve a desired cross-sectional area of reduced size. Also disclosed are preferred methods for differentiating formed bodies using the flow cell of the invention. | 11-18-2010 |

20090304905 | Coating for Sensing Thermal and Impact Damage - Coating compositions containing resins with dispersed nanoparticle precursors and methods for using said coatings as visual indicators of thermal and impact damage. The nanoparticle precursor/resin system reduces the nanoparticle precursor to its nanoparticle state when subjected to heat and/or physically impacted.

Microencapsulated leuco dyes are utilized to impart color when the coating is struck. The dye within the microcapsule is released as the microcapsule wall bursts or melts. Solubillizing agents can be utilized to improve the solubility of the nanoparticle precursor in the resin. | 12-10-2009 |
