Title: Method for determining formation porosity and gas saturation in a gas reservoir
Inventor: GUO PINGJUN
IPC: G01V5/12
Filed: 2005-05-26
Abstract: Measurements made with porosity and density logging tools in a gas reservoir may differ due to invasion effects. The effects are particularly large on measurement-while-drilling applications where invasion is minimal. Using a Monte-Carlo method, a relationship is established between true formation porosity and porosity estimates from density and porosity tools. This relationship is used on real data to get an improved estimate of formation porosity and of gas saturation.

Title: Surgical stapling instrument incorporating a multi-stroke firing mechanism with a flexible rack
Inventor: SHELTON FREDERICK E
IPC: A61B17/00
Filed: 2006-12-20
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A flexible rack transmits these firing strokes to a firing rod that reciprocates in an elongate shaft to actuate the end effector. The flexible rack advantageously stows into a pistol grip of the handle when retracted to minimize handle length.

Title: Pressure exchanger for transferring pressure energy from a high-pressure fluid stream to a low-pressure fluid stream
Inventor: HAUGE LEIF
IPC: B01D63/00
Filed: 2005-08-10
Abstract: A pressure exchanger for transferring pressure energy from a relatively high-pressure fluid stream to another relatively low-pressure fluid stream is provided. A ducted rotor is positioned on a central axle between two end covers inside a pressure vessel with a coaxial inlet and outlet pair that is in communication with a pair of low pressure ports having inclination forming an inlet tangential velocity vector in the direction of rotor rotation and an outlet tangential velocity vector in opposite direction imparting a rotational momentum on rotor. A pair of high-pressure ports is adapted for flow without inclination and imparts no momentum to rotor and flow can be varied without impacting the rotor's RPM. The end covers have a sloped surface following a flat sealing area that increases the clearance in the direction of rotation causing increased outflow during depressurization and lower duct pressure before duct is exposed to low pressure port and furthermore causing increased inflow during the pressurization phase before duct is exposed to the high pressure port, which will dissipate pressure energy as opposed to producing cavitation or pressure waves with result wear and noise.
