Title: Hydrogen combustion robotic propulsion engine
Inventor: PALMA FLORENCIO NETO
IPC: F02K9/58
Filed: 2001-08-03
Abstract: Computer controlled hydrogen combustion robotic propulsion engine including a circular-elliptical thermally insulated high pressure and high temperature combustion chamber interfaced by a flange port having a concentric spark plug threaded port and a threaded steel tube coupling; The flange forms a watertight manifold port with inner face nozzle orifices drilled concentric to facilitate ignition and cooling of the spark plug. A common steel tube is coupled to the flange port and two check valves each leading to an electric servo-valve and pressurized water and hydrogen fuel supplies. A piston pressure regulated servo-check-valve at the opposite exhaust outlet port having a compression spring and a pressurized air supply to provide steam operating pressure and temperature control within the combustion chamber for Z axis propulsion control according to a pressure transducer. Two encoded electric servomotors interfaced to the exhaust propulsion steering nozzle X and Y-axis provide jet propulsion steering according to manual or automatic computer control. The water and hydrogen combustion engine has numerous potential applications including aircraft, propulsion to conventional power plants as an environment friendly replacement to conventional boilers for electric power generation.

Title: Culture medium to improve the purity of myoblast culture
Inventor: TREMBLAY JACQUES P
IPC: C12N5/077
Filed: 2001-08-02
Abstract: The present invention relates to an improved culture medium that allows the preferential growth of myoblasts over fibroblasts.  Specifically, a culture medium disclosed by Ham et al. was modified by substituting a part or the totality of L-valine with D-valine. This improved culture medium allows the selection of primary myoblasts from fibroblasts, since the fibroblasts cannot use D-valine while the myoblasts can.

Patent CA-2384810-A1 (CA)
Inventor: DOBIN MARK W
IPC: E21B49/00
Filed: 2000-09-20
Abstract: There is disclosed herein a systematic, computationally-efficient, two-stage method for determining well locations in a 3D reservoir model while satisfying various constraints including:  minimum interwell spacing, maximum well length, angular limits for deviated completions, and minimum distance from reservoir and fluid boundaries. In the first stage, the wells are placed assuming that the wells can only be vertical. In the second stage, these vertical wells are examined for optimized horizontal and deviated completions. This solution is expedient, yet systematic, and it provides a good first-pass set of well locations and configurations. The first stage solution formulates the well placement problem as a binary integer programming (BIP) problem which uses a "set-packing" approach that exploits the problem structure, strengthens the optimization formulation, and reduces the problem size. Commercial software packages are readily available for solving BIP  problems. The second stage sequentially considers the selected vertical completions to determine well trajectories that connect maximum reservoir pay values while honoring configuration constraints including: completion spacing constraints, angular deviation constraints, and maximum length constraints. The parameter to be optimized in both stages is a tortuosity-adjusted reservoir "quality".  The quality is preferably a static measure based on a proxy value such as porosity, net pay, permeability, permeability-thickness, or pore volume. These property volumes are generated by standard techniques of seismic data analysis and interpretation, geology and petrophysical interpretation and mapping, and well testing from existing wells. An algorithm is disclosed for calculating the tortuosity-adjusted quality values.

Inventor: PAXTON GREGORY MARK
IPC: B01D3/06
Filed: 2001-02-02
Abstract: A distillation system (10) is provided for recovering water from sea water and other polluted water source. The system (10) has a heat engine (12) embodying Carnot cycle and a Rankine cycle formed by heat exchangers (16 and 24), flash evaporator (26) and condenser (32). Burnt gases from the engine (12) such as a jet engine no longer fit for flying are directed into a duct (14) where the exchangers (16) and (24) are located. Sea water is pumped into the heat exchanger (24) for preheating by residue heat in the duct (14) and then into the exchanger (16) for further heating. A recirculating pump (20) raises water pressure in the exchanger (16) for increasing boiling point to about 165 ~C.  The heated water is fed into the evaporator (26) where it changes into vapour and the condensed into water by the condenser (32). The jet air stream is used to create Venturi effect for maintaining sub-atmospheric pressure in the evaporator (26). Any solid left in the evaporator (26) is removed by a transfer mechanism (50).
