Patent CA-2098284-A1 (CA)
Inventor: HUTSON WILLIAM H
IPC: G01S15/66
Filed: 1991-12-13
Abstract: A multi-dimensional processing and display system is used with a sonar tracking system (30) to monitor ocean-going vessels (32).  The system arranges data in a three-dimensional matrix, which is then reformatted into a two-dimensional matrix.  The two-dimensional matrix is decomposed into singular vectors and singular values.  Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected singular values.  Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected singular values.  A history database is maintained by saving certain of the singular vectors, which is concatenated with the two-dimensional matrix.  An enhanced two-dimensional matrix is generated by multiplying the two-dimensional concatenated matrix by the modified singular values and the singular vectors.  After data enhancement, the two-dimensional enhanced matrix is reformatted back into a three-dimensional matrix.  All or portions of the enhanced three-dimensional matrix can then be displayed.

Title: Method and apparatus for recycling scrap mineral fibers
Inventor: RICHARDS RAY S
IPC: C03B5/00
Filed: 1992-03-03
Abstract: A method and apparatus for recycling scrap mineral fibers (42) having an organic binder coating in a highly stirred glass melter (16) wherein the organic binder coating is decomposed by applying heat. Carbon from the organic binder coating is oxidized on the surface of the glass melt (17). After oxidizing the carbon, the glass fibers are dispersed into the melt. Residual carbon may be oxidized after inclusion in the melt. Purified glass suitable for forming glass fibers is further processed by conventional glass fiber forming equipment. The method may also include the step of pre-processing the glass fiber scrap by shredding or pulverizing to facilitate feeding the glass fiber scrap to the highly stirred glass melt. The apparatus according to the present invention is preferably a stirred melter (16) having electrical joule effect heating. An impeller (22) in the glass melt stirs the melt at a high rate of speed to provide a draw down effect pulling fibers into melt.

Title: Leak Detector for Gas Air Bag Inflator
Inventor: STARKOVICH JOHN A
IPC: B60R21/26
Filed: 1994-10-25
Abstract: The present invention relates to a detector for detecting leaks of a gas.  The present invention is particularly applicable to a vehicle occupant restraint apparatus (10) which has a container (14) for an exothermically reactable gas mixture (18).  An exothermic reaction of the gas mixture (18) released from container (14) deploys an occupant restraint (12).  The detector has an electrically conductive sensor element (44).  The sensor element (44) is positioned within an envelope (40) surrounding a portion of container (14) so as to be exposed to the gas mixture (18) if leaked from container (14).  The sensor element (44) is part of an electric circuit (46).          The electrical resistance of the sensor element (44) varies when the sensor element is exposed to the leaked gas mixture.  The electric circuit (46) also has a power source (64) including a timing circuit (52) for providing an intermittent electric current through the sensor element (44).  The timing circuit (52) has an off-period of relatively long duration.  This allows the gas if leaked into the envelope (40) to accumulate in the area of the sensor element (44).
