Patent CA-2613993-A1 (CA)
Title: Distance-dependent spectra with uniform sampling spectrometry
Inventor: GURUPRASAD VENKATA
IPC: G01S11/02
Filed: 2006-02-14
Abstract: In a receiver of electromagnetic or other waves (210-230), scaling of received frequencies in proportion to the respective source distances, so as to reveal the source distances and permit isolation of signals from a particular source by simple spectral filtering. Phas differences between transmitted frequencies due to the common source path lead to chirp eigenfunctions registering in the receiver as scaled frequencies. The chirps are extracted by implementing exponentially varying path delays in autocorrelators and diffractive spectrometers say using a medium (300) with variable refractive index .eta.(t). Analogous exponentially varying phase shifts are applied to successive samples in the kernel of discrete Fourier transform implementations. Advantage lies in enabling distance-dependent frequency scaling in autocorrelation spectroscopy, as well as in conventional diffractive or refractive spectrometers or digital signal processing with uniform sampling.
Patent CA-2615431-A1 (CA)
Inventor: SCHNEIDER GLENN
IPC: E21B43/18
Filed: 2007-12-20
Abstract: A method and apparatus for increasing the production of a hydrocarbon well by removal of accumulated formation fluid from the bottom of the well.  The apparatus includes a body positionable down hole and a sealing assembly, with a converging-diverging nozzle installed axially within a through bore extending through the body at a position below the sealing assembly. A fluid lift passage extends from the accumulated formation fluid through the body and into the throat of the nozzle. The entrance into the throat of the nozzle includes inwardly tapered shoulder portion position below the opening of the fluid lift passage into the throat. The apparatus creates a low-pressure zone within and lifts the accumulated formation fluid into the throat where it is atomized by a high velocity flowing production gas. The atomized fluid is carried to the surface of the well by the production gas where it is then separated from the gas. The method includes the installation of an apparatus within the well.

The pinions are in each axial position in a positive fit with the drive organ. One of the two pinions, respectively, can be locked in a torque fixed manner with one of the two pinions having the same diameter.

Title: Spinner for manufacturing dual-component irregularly-shaped hollow insulation fiber
Inventor: BANASZKIEWICZ STAN
IPC: D01D5/253
Filed: 2008-06-25
Abstract: A novel spinner, for fiberizing hollow, irregularly-shaped insulating fibers is the subject matter of the present invention. The spinner is unique in a sense that its hole/slot pattern can be done by some standard drilling/milling techniques, which lower the cost of manufacturing. The invention uses two molten glasses (A and B) of different coefficients of thermal expansion, which are moved outwardly around the corresponding gas orifices by centrifugal force in a spinner pot. A stream of pressurized combustion gases is thrust through these central gas orifices to produce a hollow, non collapsible fiber of irregular shape. Molten glass A is introduced from the bottom of the spinner, and molten glass B is introduced above an uppermost flange and by means of centrifugal force, the two glasses A and B are forced upwardly and downwardly, respectively, into fiberizing centers. The improvement of the present invention is that by using both horizontal baffles and vertical compartments, a greater number of fiberizing orifices can be created on the spinner outside peripheral side wall.
