Patent CA-2808083-A1 (CA)
Inventor: ROUTH PARTHA S
IPC: G01V1/40
Filed: 2011-08-19
Abstract: Method for simultaneous full-wavefield inversion of gathers of source (or receiver) encoded geophysical data to determine a physical properties model for a subsurface region, especially suitable for surveys where fixed receiver geometry conditions were not satisfied in the data acquisition. First, a shallow time window of the data (202) where the fixed receiver condition is satisfied is inverted by simultaneous encoded (203) source inversion (205). Then, the deeper time window of the data (208) is inverted by sparse sequential source inversion (209), using the physical properties model from the shallow time window (206) as a starting model (207). Alternatively, the shallow time window model is used to simulate missing far offset data (211) producing a data set satisfying the stationary receiver assumption, after which this data set is source encoded (212) and inverted by simultaneous source inversion (214).

Inventor: GRAY PAUL EDWARD
IPC: C04B35/653
Filed: 2013-04-11
Abstract: A process for producing silicon-containing CMC articles. The process entails producing a matrix slurry composition that contains at least one resin binder and a SiC  powder. The SiC powder is a precursor for a SiC matrix of the CMC article and the resin binder is a precursor for a carbon char of the matrix. A fiber reinforcement material is impregnated with the slurry composition to yield a preform, which is then heated to form a porous preform that contains the SiC matrix and porosity and to convert the resin binder to the carbon char that is present within the porosity. Melt infiltration of the porosity is then performed with molten silicon or a molten silicon-containing alloy to react the carbon char and form silicon carbide that at least partially fills the porosity within the porous preform. The carbon char constitutes essentially all of the elemental carbon in the porous preform.

Title: Gas turbine engine and variable camber vane system
Inventor: RESS ROBERT A JR
IPC: F02C9/22
Filed: 2011-12-27
Abstract: A unique variable camber vane system for a gas turbine engine is provided. The variable camber vane system allows for increasing the efficiency of as gas turbine engine in a simple and reliable manner. In particular, the seal strip can be manufactured relatively easily, and additional means for fastening the seal strip to the airfoil portion are not required due to the interference fit. Furthermore, the seal can be firmly pressed with its rubbing surface onto the crown, to reduce the risk of leakage through the gap between the two airfoil portions. Accordingly, a leakage flow from the pressure side of the airfoil to the suction side of the airfoil is reduced or even prevented, so that the flow through the vane system can be controlled more accurately.

Filed: 2012-01-24
Abstract: Exemplary embodiments provide a needle shield remover (500) that reliably engages with a distal cap of an automatic injection device and with one or more needle shields coupled to a syringe of the device. When a user removes the distal cap, the needle shield remover reliably removes the needle shields (e.g., a soft needle shield and a rigid needle shield) from the syringe, thereby exposing the injection needle for performing an injection. In an exemplary assembly method, a needle shield remover is engaged to a needle shield coupled to a syringe, prior to insertion of the syringe and needle shield remover assembly into a housing of the device. This exemplary assembly method allows visual inspection, outside the housing of the device, to ensure that the needle shield remover is correctly and reliably engaged to the needle shield before the syringe and needle shield remover assembly is inserted into the housing.
