20110089498	INTEGRATION OF LOW AND HIGH VOLTAGE CMOS DEVICES - A method of fabricating a semiconductor device is provided that includes providing a semiconductor substrate having a first portion and a second portion, forming a first transistor in the first portion of the substrate, the first transistor being operable at a first voltage, and forming a second transistor in the second portion of the substrate, the second transistor being operable at a second voltage greater than the first voltage. The formation of the second transistor includes forming an extended feature of the second transistor with a photomask that is used to adjust a threshold voltage of the first transistor.	04-21-2011

20110094953	CHROMATOGRAPHY COLUMN - A chromatography column includes a tube, a fit assembly, a first end fitting and a second end fitting. An annular protrusion extends from an end face of the tube to a protrusion height and circumscribes a chamber in fluid communication with the axial bore. Both the chamber and the bore may be filled with a packing material. The fit assembly includes a deformable ring having a yield strength less than a yield strength of the annular protrusion. The ring contacts the annular protrusion such that the frit assembly provides a chamber boundary that retains the packing material. The first end fitting is securely fastened to the tube such that the ring is axially compressed and deformed around the annular protrusion, the chamber height is less than the protrusion height, and the packing material is compressed.	04-28-2011
