Patent CA-2360511-A1 (CA)
Inventor: APPELLA ETTORE
IPC: C07K16/00
Filed: 2000-01-25
Abstract: The present invention provides methods for generating phosphorylation site- specific immunological reagents. More specifically, a phosphopeptide mimetic  is incorporated into a polypeptide in place of a phosphorylated amino acid. The polypeptide is used as antigen by standard methods to generate either monoclonal or polyclonal antibodies which cross-react with naturally phosphorylated polypeptide. The phosphopeptide mimetic preferably contains a  non-hydrolyzable linkage from the appropriate carbon atom of the amino acid to a phosphate group. A preferred linkage is a CF2 group. Such a linkage is use d to generate the phosphoserine mimetic F2Pab, which is incorporated into a polypeptide sequence derived from p53 to produce antibodies which recognize a specific phosphorylation state of p53. A CF2 group linkage is also used to produce antibodies to produce the phosphothreonine mimetic F2Pmb, and to produce the phosphotyrosine mimetic, F2Pmp.

Inventor: COLLOT ANDRE CLAUDE FELIX
IPC: B23K20/12
Filed: 2001-12-03
Abstract: A tool for holding a blade blank (1) comprises a frame (13) in which a control system using clamping jaws (18, 19) and lifters (30, 34, 35) grips the blade and holds it in position vertically on two supporting faces (22, 23), while the blade has been laid on three lateral faces (41, 42, 43).

Patent CA-2368974-A1 (CA)
Title: Large area low mass ir pixel having tailored cross section
Inventor: HIGASHI ROBERT E
IPC: H04N5/33
Filed: 2000-03-10
Abstract: The present invention provides a much more optimum design for an infrared pixel microstructure. The configuration of the microstructure itself is designed to optimum operational characteristics including faster speeds than previously available. These faster speeds are achieved by reducing the thermal mass of the pixel itself, thus directly affecting the pixels associated thermal time constant. Thermal mass is reduced by tailoring the cross section of the pixel structure such that protective layers are substantially reduced in areas where they are not necessary. This results in the desired reduction and overall pixel mass and consequently more optimum pixel performance.
