Title: Method for removing chrome and/or nickel from liquid slags
Inventor: EDLINGER ALFRED
IPC: C21B3/06
Filed: 2001-01-18
Abstract: The invention relates to a method for removing chrome and/or nickel from liquid slags, or slag mixtures, whereby the liquid slag is charged onto a metal bath, in particular an Fe-bath, and reduced, by contacting with carbon, or a carbon support. The introduction of carbon into the metal bath is carried out in order to reduce the Cr and Ni oxide content of the slag, to a value between 0.8 wt. % and 0.2 wt. %.On reaching the predetermined Cr oxide content of the slag, reducing agents with greater reducing potential, for example, Al, Ca, Si, Fe-Si or Ca-Si are added to reduce the Cr and Ni oxide content to below 0.15 wt. %, preferably below 0.08 wt. %.

Title: Uv-assisted grafting of pes and psf membranes
Inventor: BELFORT GEORGES
IPC: C08F291/06
Filed: 2001-10-04
Abstract: An ultrafiltration membrane is modified to exhibit low protein fouling and yet maintains a greater fraction of the original membrane permeability and retention properties after modification. This is achieved by grafting monomer onto the surface of a highly photoactive membrane such as polyethersulfone, via the process of dipping the polymeric membrane into a solution containing one or more monomers and a chain transfer agent, removing the membrane from the solution, securing the membrane inside of a quartz vessel contained within another vessel of liquid filter, and irradiating the membrane with a UV light at a wavelength between the range of 280nm and 300 nm. High density grafting and shorter grafted monomer chain length result in low protein fouling and retention of permeability.

Title: Double and triple readout assay systems
Inventor: KIM TAE KOOK
IPC: C12Q1/6897
Filed: 2001-10-25
Abstract: The present invention provides assays for identifying compounds that affect the transcriptional activity of a protein of interest or affect the stability of the protein of interest. The triple readout assay system which can be used to identify compounds that affect the transcriptional activity of a protein of interest uses three cell lines to control for non-specific effects such as sequences flanking the inserted gene and cytotoxicity. The double readout assay system assesses protein stability and uses a fusion protein of a reporter and the protein of interest. These assay systems may be particularly useful in identifying compounds that affect transcription factors and tumor suppressors. In a particular embodiment, the tumor suppressor p53 is the target protein being studied.
