Title: Oxidation of peptides
Inventor: SABATIER JEAN-MARC
IPC: C07K1/113
Filed: 2004-05-28
Abstract: The folding/oxidation of a reduced peptide or partially reduced peptide to form a disulphide bridged peptide is effected by dissolving it in an oxidizing organic solvent, alone or in admixture with water, adding an aqueous alkaline buffer to the solution, and recovering the resultant disulphide bridged peptide. The preferred oxidizing organic solvent is dimethylsulphoxide, which is desirably used as a 10 to 50% aqueous solution. The addition of the aqueous alkaline buffer, which is preferably a 0.2 M Tris-HCI buffer, is preferably added during a period of from 5 to 90 minutes after dissolution of the reduced peptide in the oxidizing organic solvent. The method allows reduced peptides which are insoluble in alkaline conditions to be oxidized and allows reduced peptides which may form stable but inactive oxidized species if treated with dimethylsulphoxide alone to be fully oxidized.

Title: Flow meter having an optical encoder and an algorithm to selectively block signal transmission
Inventor: WINTER DAN
IPC: G01D5/28
Filed: 2004-06-10
Abstract: A water meter has a meter register having an encoder having electromagnetic wave emitters, e.g., infrared emitters to measure water flow and direction of water flow through the meter. The encoder has two of three spaced emitters directing infrared rays at predetermined time intervals toward a rotating detector wheel having a reflective surface portion and a non-reflective surface portion facing the emitters and an infrared sensor. The reflective surface portion of the detecting wheel reflects the infrared rays incident thereon toward the sensor. A microprocessor connected to the sensor acts on signals from the sensor to determine material flow. The meter register transmits the signal to a distant receiver. The microprocessor of a meter register has an algorithm to prevent the meter register from sending signals until after the meter register or a water meter having a meter register is installed and water moved through the meter.

Title: Arrangement for managing voice over ip (voip) telephone calls especially unsolicited or unwanted calls
Inventor: KEALY KEVIN BRIAN
IPC: H04M3/436
Filed: 2006-01-17
Abstract: Trust ratings are embedded in certificates of calling devices in a Voice over Internet Protocol (VoIP) communications system: A method of managing trust ratings involves automatically accumulating complaints concerning VoIP calls initiated from calling devices, and comparing respective quantities of accumulated complaints associated with each calling device. When a quantity of accumulated complaints associated with a given calling device exceeds a given threshold, a trust rating of the given calling device is reduced. In subsequent VoIP calls the given calling device attempts to place, the reduced trust rating is included in the call request so that the subsequent calls are subject to more austere call screening operations than calls having the unreduced trust rating. Call recipients thus affect the calling device's trust rating simply by entering complaints associated with received calls. The method effectively combats spam over Internet telephony (SPIT) through participation of called parties.

Title: System for drilling oil and gas wells using a concentric drill string to deliver a dual density mud
Inventor: DE BOER LUC
IPC: E21B7/128
Filed: 2004-10-29
Abstract: A system for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in offshore and land-based drilling applications is disclosed. The present invention combines a base fluid of lesser/greater density than the drilling fluid required at the drill bit to drill the well to produce a combination return mud in the riser. By combining the appropriate quantities of drilling mud with a light fluid, a riser mud density at or near the density of seawater may be achieved to facilitate transporting the return mud to the surface.  Alternatively, by injecting the appropriate quantities of heavy fluid into a light return mud, the column of return mud may be sufficiently weighted to protect the wellhead. At the surface, the combination return mud is passed through a treatment system to cleanse the mud of drill cuttings and to separate the drilling fluid from the base fluid. The present invention further includes a control unit for manipulating drilling fluid systems and displaying drilling and drilling fluid data.
