Title: Ferric and acid complex
Inventor: FRIEDRICH KLAUS
IPC: C07F15/02
Filed: 2006-06-07
Abstract: A ferric and acid complex includes the reaction product of a chelant, iron oxide, a base, and a reaction promoter. The chelant has at least one carboxylic acid functionality. The reaction promoter has an Fe3+ ion. A  process for preparing the ferric and acid complex in a vessel includes charging solvent, the chelant, the base, the iron oxide, and the reaction promoter into the vessel. The solvent, chelant, base, iron oxide, and reaction promoter are heated to a temperature of at least 170 ~F for a period of at least about 3 hours to form the ferric and acid complex. Due to the use of the reaction promoter having the Fe3+ ion, the process for preparing the ferric and acid complex results in reduced degradation of the chelant during processing and, thus, a high quality ferric and acid complex.

Patent CA-2622106-A1 (CA)
Inventor: REDEMSKE JOHN A
IPC: B22D29/06
Filed: 2008-02-25
Abstract: A fugitive pattern, such as wax or other meltable pattern material, residing inside of a refractory mold, which can be unsupported or supported in a particulates bed, is removed by discharging steam or other condensable vapor that may include a surfactant inside the mold to contact and melt the pattern while an exterior of the mold is subjected to a non--condensing gas atmosphere such as air outside of the mold. Regardless of whether the condensable vapor includes surfactant or not, the mold can be tilted relative to gravity and rotated while it is tilted to improve the pattern removal. Condensable vapor is condensed inside the mold where the vapor has contacted the pattern while the exterior of the mold remains free of condenate. The condensed vapor and melted pattern material are drained out of the mold with the surfactant, if present, improving drainage.

Title: Protein-protein interaction detection system using fluorescent protein microdomains
Inventor: CABANTOUS STEPHANIE
IPC: C12Q1/02
Filed: 2005-12-03
Abstract: The invention provides a protein labeling and interaction detection system based on engineered fragments of fluorescent and chromophoric proteins that require fused interacting polypeptides to drive the association of the fragments, and further are soluble and stable, and do not change the solubility of polypeptides to which they are fused. In one embodiment, a test protein X is fused to a sixteen amino acid fragment of GFP (.beta.-strand 10, amino acids 198-214), engineered to not perturb fusion protein solubility. A  second test protein Y is fused to a sixteen amino acid fragment of GFP (.beta.-strand 11, amino acids 215-230), engineered to not perturb fusion protein solubility. When X and Y interact, they bring the GFP strands into proximity, and are detected by complementation with a third GFP fragment consisting of GPF amino acids 1-198 (strands 1-9). When GFP strands 10 and 11 are held together by interaction of protein X and Y, they spontaneous association with GFP strands 1-9, resulting in structural complementation, folding, and concomitant GFP fluorescence.
