Patent CA-2519808-A1 (CA)
Title: Correction of troposphere induced errors in global positioning systems
Inventor: POWE MATTHEW DUNCAN
IPC: G01S5/00
Filed: 2004-04-19
Abstract: A method of obtaining data for use by a receiver of a satellite positioning system or a GNSS comprises deriving the data remotely from the receiver by a server (200), using meteorological information and a regional or global three dimensional map of grid points from which it computes tropospherical delays by ray tracing through the refractivity field derived from atmospheric measurements of pressure, temperature and water data content, such measurements being available from meteorological bodies. When used to enhance position determined by a user receiver that includes a non-meteorological, climate based model (130) giving zenith delays and means (130') to map them to particular inclinations, the server also includes a copy of such non-meteorological model (230) and provides its ray traced delay values as zenith delays. The sets of zenith delay values for corresponding grid points are compared in the server (260) and modifications developed (preferably in fractional form) by which the non-meteorological delay values require correcting to be accurate. The correction sets are reduced by image compression techniques (270) and transmitted via the satellites (1101 etc) of the GNSS at low data rate to the user receiver, which receiver simply applies the corrections to the Zenith delays derived by its own model. If a user position is known, the server may derive accurate tropospheric delay values directly for the receiver position directly for transmission.

Patent CA-2560499-A1 (CA)
Title: Enhanced reverse buckling rupture disc
Inventor: MOZLEY ROBERT M
IPC: F16K17/16
Filed: 1999-03-15
Abstract: An improved reverse rupture disc for use as a safety pressure relief device is provided. The disc is defined by an annular flat flange region, a concave-convex disc dome region and a transition region that joins the disc-shaped flat flange region to the concave-convex disc dome region. One or more deformations may be formed at or near the apex of the disc dome region for weakening the disc to the point that incidental damage to the disc will not weaken the disc any further, thereby ensuring that the disc will reverse at a certain pressure, and no lower. The disc may also formed with one or more irregular transition regions at the base of the disc and a partial circular groove in the transition region. The irregular transition region of the disc cooperates with a shear enhancing means such as a protrusion or notch formed in a support ring or disc holder disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region. A back pressure support means extends over the transition region and potentially over the dome region to prevent vacuum and forward to reverse cyclical pressures in the convex direction from damaging or destroying the disc. An ungrooved region of the transition region acts as a hinge holding the ruptured disc dome to the flat flange region after the disc has ruptured. The ruptured disc dome hangs over an arcuate projection formed in the support ring or disc holder, which helps to prevent the disc from fragmenting.
