Inventor: DAVIS JEFFREY P
IPC: H04M7/00
Filed: 1994-06-28
Abstract: A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site.  The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites.  The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data.  The connection between the local site and a second site is a voice only connection allowing the first remote site to talk to the second remote site without breaking the data communication connection between the first site and the local site. The second remote site amy be a public telephone network.  The communication between the first remote site and the second remote site through the local site may also be a data communication connection, or it may also be a voice over data communication connection.

Title: Improved microbial production of indigo
Inventor: LAUFF JOHN J
IPC: C12N15/55
Filed: 1996-11-19
Abstract: There is provided an improved process for the biosynthetic production of indigo, the improvement comprising removing unwanted by-products such as isatin or indirubin from the broth in which such indigo is produced. Isatin can be removed by enzymatic activity using an isatin-removing enzyme such as an isatin hydrolase, or by other techniques such as process parameters (elevated temperature, pH), or by contacting the broth containing the isatin with appropriate adsorption compounds/compositions such as carbon or appropriate resins. Since isatin is the precursor of indirubin, the indirubin levels are decreased as a result of isatin removal.

This   simulates   the illumination of the diode,  and generates on the common output (SC), instead of said measurement signal,  a signal representative  of  the  functioning  of  the  cell  thus addressed.
Patent CA-2242851-A1 (CA)
Inventor: CHAKRABARTTY AVI
IPC: G01N33/68
Filed: 1996-08-16
Abstract: The invention is a method for in vitro monitoring of peptide or protein fibril assembly. In order to provide sensitivity at nanomolar concentrations on the order of that observed in vivo, the method makes use of fluorescent energy transfer between closely juxtaposed donor and acceptor fluorophores. Accordingly, the invention requires attaching a donor fluorophore to a fibrillogenic peptide or protein, and attaching an acceptor fluorophore to a second fibrillogenic peptide or protein. The donor and acceptor fluorophores are located on the first and second peptides or proteins so that they are juxtaposed to permit energy transfer between them upon fibril formation. The fluorophore-containing peptides or proteins are mixed in solution at a normal physiological concentration, and fibril formation is monitored by observing the fluorescence energy transfer between the donor and acceptor fluorophores. Mixing is preferably done by providing equimolar amounts of peptides or proteins in a denaturant solution, and monitoring of fibril formation is initiated by diluting out the denaturant.
