Patent CA-2365638-A1 (CA)
Title: Tracheal tubes
Inventor: NASH JOHN EDWARDS
IPC: A61M/
Filed: 2001-12-20
Abstract: Conventional tracheostomy tubes have a sealing cuff inflated by an inflation lumen extending along the tube. The tube may also have a suction lumen opening just above the cuff to enable collected secretions to be removed. In the present invention the tracheostomy tube is moulded and has channels extending along opposite sides for a suction tube and an inflation tube. The suction tube opens into a recess on the outside of the tracheostomy tube through a side opening oriented at right angles to the radius of the tracheostomy tube. The recess extends around about 90° of the tube towards its outer curve so that secretions collecting in this region can be removed.

Title: Inspection of matter
Inventor: JOHANSEN IB-RUNE
IPC: G01N21/25
Filed: 2000-03-20
Abstract: Apparatus for automatically inspecting a stream of matter comprises lamps (38) which emit a detection medium, such as IR or visible light, to be active at the matter, a rotary polygonal mirror (19) which receives from a multiplicity of detection zones Z at the matter detection medium which has been varied by variations in the matter, an optional detection device (22) which receives the varied medium by reflection from the mirror (19), to detect a plurality of wavelengths of the varied medium substantially simultaneously, and to generate detection data in respect of that plurality of wavelengths substantially simultaneously and in dependence upon the variations in the medium, and a microprocessor (26) which obtains the detection data from the device (22).  The beams B of the varied medium which are received at the device (22) and emanate from the zones Z travel along respective paths from the matter to the mirror (19) which paths converge continuously with respect to each other from the matter to the mirror (19).  Those paths may extend to the mirror (19) indirectly by way of at least one planar mirror (80), or directly to the mirror (19), in which latter case the axis of the mirror (19) would be substantially parallel to the direction D of advance of the matter.

Abstract: In the method of manufacturing a ferrule, electrocasting is carried out using at least one wire 9 such as of a metal or a plastic as a mother die, and then the wire 9 is removed from the resulting electrocast product, wherein the electrocasting treatment is carried out under rotation of the wire while it is maintained static in the longitudinal direction. According to this method, neither biased thickening nor bending occurs in the electrocast products, and they are almost free from decentering of holes. Intermediate rod products obtained after the electrocasting treatment have perfectly circular cross sections. In addition, variation in the diameter of the rod products can be reduced. Besides, agitation of the electrocasting solution can be facilitated by employing a method in which agitation is achieved by forced circulation of the liquid, and further deterioration of the electrocasting working environment can be prevented.

Abstract: An explosive charge such as a cast booster charge (10, 110, 210) includes an explosive charge (14, 114, 214) having a first explosive matrix material (114a, 214a) with discrete bodies (118, 218) of a second material embedded therein. In some embodiments, discrete bodies may comprise explosive material and the first explosive matrix material (114a, 214a) may be more sensitive to initiation than the explosive material of the discrete bodies (118, 218). In a separate aspect of the invention, the discrete bodies may have a minimum dimension of at least 1 millimeter or, optionally, 1.6 millimeter, regardless of the explosive properties of the material therein. In a particular embodiment, discrete bodies may be shaped as cylindrical pellets rounded at at least one end. The cast booster charge (10, 110, 210) may be produced by melting the first explosive, disposing discrete bodies therein and cooling the molten material to solid form.

Title: Treatment of oxidable gas generated from waste at a dumping area
Inventor: ETTALA MATTI
IPC: B01D53/85
Filed: 2000-09-01
Abstract: The invention relates to the method for treating oxidable gas generated from waste at a dumping area and to the structure of the dumping area constructed for the method. As the dumping area has been filled up, the organic waste layer (1) is cov-ered with a sealing layer (2) preventing the absorption of water and with an overly-ing layer, typically a drying layer (3) and a surface layer (4). In oxygen-free condi-tions in the waste layer (1), oxidable gas, mainly methane, is generated, which is, according to the invention, directed in a self-operated manner through the penetra-tion aperture (10) formed to the sealing layer and made to spread in the lateral direc-tion with the help of one or several flow controllers so that the gas ends in the sur-face layer (4), in which it becomes biologically oxidised because of the effect of microbes. The penetration aperture may be formed of the well (10) provided with the cover (11), and the gas flow controllers may be perforated pipes (12) extending radially from the side of the well. The oxidation of gas may be intensified by direct-ing air and/or moisture from the piping (15) to the surface layer (4).

Title: Improvements in community energy consumption management
Inventor: EDWIN RICHARD
IPC: H02J3/00
Filed: 2002-05-31
Abstract: A networked intelligent energy management system (NIEMS) provides the capability for a community NIEMS server to schedule jobs to be done in each household in a community, based on the availability, monetary cost and/or environmental cost of the energy required to complete a specific job, for example a washing cycle in a washing machine. NIEMS therefore smoothes the load placed on energy resources.      In particular the system reduces the peak load on the energy supply. The system allows a community to make the best use of energy resources. The energy requirements and usage of the community can be tailored to favour usage of preferred and/or available energy resources, for instance by favouring the use of renewable or green energy resources over the use of fossil fuels.

Title: Systems and methods for collecting, storing, and analyzing database statistics
Inventor: TUCKER BRENT DAVID
IPC: G06F17/30
Filed: 2000-11-09
Abstract: A system and method for collecting, storing, retrieving and analyzing database statistical information. A collection agent on a database server interrogates the database on a defined interval to determine the database state, and to derive statistics about database performance, structures, and usage. This statistical information is stored within a collection database as historical data. Periodically, the historical data is unloaded from the collection database, transferred via a Transfer Protocol to a data warehouse server, and loaded into said server. Summarization of the data, and Trends-based analysis, are performed against the data with results stored in the data warehouse as persistent storage. Periodically, an application server interrogates the data warehouse for the database being analyzed, and produces a series of reports which show database trends, reliability, and performance information in graphical, textual, and tabular formats.

Abstract: A system and method for defining rewriteable data storage media defined by ECMA Standard ECMA-272 2nd edition (1999) for 120 mm DVD rewriteable disk (D VD- RAM) as a write once data storage media and for storing data thereon. The apparatus consists of a data storage device for reading and writing data on the media, the media, a media type indicator in the media, two write protect  flags in the user data area of the media, and programming to examine the two  write protect flags prior to a write, erase, or format operation. If both flags match and the media type indicator is write once, the drive is prevent ed from writing to the user data area if both flags are in the data written state. If both flags do not match after two re-reads, an error message is generated. If both flags are in the data unwritten state, data is written to  the user data area and both flags are set to the data written state.
