Patent CA-2141316-A1 (CA)
Inventor: URBANSKI STEVEN A
IPC: G10L21/0232
Filed: 1994-04-23
Abstract: An improved method and an apparatus for reducing an undesirable characteristic of a spectral estimate of a noise signal (203) between occurrences of voice signals (202) in an input signal (117). A spectrum of the input signal (117) is estimated to produce a spectral estimate (119) of the input signal (117) including the undesirable characteristic of the noise signal (203). The spectrum of the input signal (117) is smoothed over a first bandwidth (f3-f4) during the occurrences of the voice signals (203) and over a second bandwidth (f2-f5), substantially greater than the first bandwidth (f3-f4), between the occurrences of the voice signals (203). Alternatively, the spectral estimate (119) of the input signal (117) is filtered between the occurrences of the voice signals (203). Alternatively, the significance of magnitude and/or phase components of poles (301-305), representing the spectral estimate (119) of the input signal (117), between the occurrences of the voice signals (203) is reduced to produce a modified spectral estimate (120) of the input signal (117) between the occurrences of the voice signals (203).

Title: Liner cementing system and method
Inventor: GAMBERTOGLIO LOUIS M
IPC: E21B33/14
Filed: 1995-05-12
Abstract: A liner cementing system and method provide for a landing collar 10 with a bypass passageway 45. Circulation port 62 in collar 10 permits initial circulation through the liner 17 until a pump down plug P1 is pumped therein to seal off circulation therethrough. An increase in pressure in the liner bore 51 acts on a piston 50 until shear ring 48 is sheared at a selected pressure. Cement 90 may then flow through the bypass passageway 45 into a cement shoe 104 and into an annulus 74 to cement the liner 17 in place. Pump down plug P2 seals off the bypass passageway 45 to stop flow into the annulus 74. The closing of circulation port 62, the opening of bypass port 53, and the closing of bypass port 53 produce pressure signals at the surface which may be used to analyze cement job success.

Abstract: A fuel cell which is operated at a temperature which is not greater than substantially 250°C, has an electrolyte which can be a solid polymer electrolyte, a liquid phosphoric acid electrolyte, or a liquid alkaline electrolyte, and a cathode and an anode each comprising a platinum catalyst.  Hydrogen fuel gas is supplied to the anode and a gaseous oxidant, for example oxygen is supplied to the cathode.  The cathode and anode are both connected to first and second circuits in parallel.  The first circuit includes a load to be powered by the fuel cell and a first switch.  The second circuit includes a battery and a second switch.  The switches are operated by a control.  When the first switch is closed the cell powers the load and second switch is open.  When the first switch is open the second switch is closed so the battery applies a reverse D.C. potential to the anode and cathode.  The first switch is closed and the second switch is open for a time period T1 which is substantially at least ten times greater than time period T2 for which first switch is open and the second switch is closed.  The time period T2 does not exceed substantially 0.25 seconds.  The switches can be relays or solid state electronic switch arrangements.
