Patent CA-2449791-A1 (CA)
Title: Storage system
Inventor: ELDON JAMES B III
IPC: F16B12/26
Filed: 2003-01-09
Abstract: A storage system including a novel shelf and bracket item holder is provided where the item holder is supported upon a planar panel. The shelf has two end edges and two shelf-brackets which include a substantially circumferential flange, a receptacle portion for receiving one of the end edges of the shelf, and an upper panel catch and a lower panel catch projecting outwardly from a same side of the circumferential flange in aligned spaced relation to one another. A cantilevered lock -release latch is positioned adjacent to the lower panel-catch so as to project from an end of the circumferential flange toward the lower panel-catch. When each of the upper and lower panel-catches are inserted through and occupy a corresponding one of the perforations in the panel such that each of the lock-release tabs of the lock-release latches engages the outer surface of the perforated panel thereby deflecting the lock-release latches away from the perforated panel, the shelf and brackets are moved relative to the perforated panel. This movement causes the lock-tabs to engage the rear surface of the perforated panel and the lock-release tabs of the lock-release latches to slide along the front surface and slip into the respective perforations occupied by the lower panel catches. This, in turn, allows the lock-release latches to spring-back and the lock-release tabs to enter the perforations occupied by their respective lower panel catches so as to secure the bracket in locked engagement with the perforated panel.
Patent CA-2455778-A1 (CA)
Inventor: RANSING RAJESH S
IPC: G16Z99/00
Filed: 2002-08-15
Abstract: Apparatus and method for determining a likely cause or the likelihood of the occurence of a cause of one or more effects, in which training data relating to previously identified relationships between one or more causes and one or more effects is used to learn the cause and effect relationship. A number of primary and secondary reference points are chosen in the input space created by belief values representing the strength of effect. A Lagrange Interpolation polynomial (or other function representing the cause and effect relationship) and a weight value is associated with each of the said reference point. Weight values associated with primary reference points are considered as independent variables (primary weight values) and other weight values, which are associated with secondary reference points (secondary weight values), depend (preferably, but not necessarily, linearly) on one or more primary weight values. Belief value in the occurence of likely causes of one or more given effects can be determined using this method or apparatus.

Title: Sealing method and device for a gas turbine shaft
Inventor: ELEFTHERIOU ANDREAS
IPC: F16J15/447
Filed: 2002-09-04
Abstract: A method and apparatus for sealing a radial gap (27) between coaxial inner and outer rotating shafts (26, 28) of a gas turbine engine includes using a radial seal (64) as a main seal to seal the gap (27) for a normal engine operation condition, and using an axial seal (70) as a back-up seal for a double seal of the gap. The radial seal (64) provides a seal which meets relatively restrictive leakage requirements for the normal engine operation condition and the axial seal (70) provides a back-up seal which meets less restrictive leakage requirements but is much more tolerant of radial displacement and vibration between the coaxial inner and outer rotating shafts. An engine operable condition is ensured under abnormal conditions, such as bird strikes, in which the coaxial relationship between the inner and outer rotating shafts (26, 28) are affected by unbalancing forces caused by the bird strike, thereby causing a failure of the radial seal.

Abstract: Thin flexible piezoelectric transducers are bonded to or imbedded into oilfield tubular members or structural members. The transducers may be used to telemeter data as acoustic waves through the members. By proper spacing of transducers and phasing of driving signals, the transmitted signals can be directionally enhanced or encoded to improve transmission efficiency. The transducers may be used for health monitoring of the tubular or structural members to detect cracks, delaminations, or other defects. The flexible transducers are very thin so that overall dimensions of tubular or structural members are essentially unchanged by incorporation of the transducers.

Abstract: The invention relates to a method for the ground-based monitoring of EWF-type anomalies in a positioning satellite signal. The inventive method is particularly suitable for use in making GPS and SBAS satellite positioning signals reliable. Said method consists in performing an instantaneous statistical analysis (for approximately 1mn) of the correlation peak of the satellite signal receiver and comparing same to a long-term statistical analysis (several hours) by choosing 5 points which are characteristic of the peak (prompt, .plusmn. 0.044 et .plusmn. 0.088). If the result of the comparison is greater than a determined threshold, the corresponding signals are rejected.
