Patent number: 7576296Abstract: An apparatus for thermal conversion of one or more reactants to desired end products includes an insulated reactor chamber having a high temperature heater such as a plasma torch at its inlet end and, optionally, a restrictive convergent-divergent nozzle at its outlet end. In a thermal conversion method, reactants are injected upstream from the reactor chamber and thoroughly mixed with the plasma stream before entering the reactor chamber. The reactor chamber has a reaction zone that is maintained at a substantially uniform temperature. The resulting heated gaseous stream is then rapidly cooled by passage through the nozzle, which “freezes” the desired end product(s) in the heated equilibrium reaction stage, or is discharged through an outlet pipe without the convergent-divergent nozzle. The desired end products are then separated from the gaseous stream.Type: GrantFiled: May 11, 2004Date of Patent: August 18, 2009Assignee: Battelle Energy Alliance, LLCInventors: James R.

Patent number: 7316680Abstract: An implantable osmotically driven delivery system having a dynamic, two-way valve and a self-adjusting, variable geometry fluid flow channel. As pressure within the agent delivery system increases, the fluid channel narrows, thereby restricting flow. At exceptionally high pressures, the valve can be designed to close altogether at the orifice or delivery end, or it can provide a minimal leak path so that a maximum fluid flow is never exceeded. At zero or very low pressures, the valve will close completely at the beneficial agent reservoir end, isolating the beneficial agent formulation from external fluid infiltration and thereby eliminating diffusion of external fluid into the beneficial agent formulation.Type: GrantFiled: September 27, 2005Date of Patent: January 8, 2008Assignee: Intarcia Therapeutics, Inc.Inventor: Scott Jay Gilbert
