Title: Laser-based communications with a remote information source
Inventor: PEASE DAVID M
IPC: H04B10/118
Filed: 2004-11-19
Abstract: System and techniques for transmitting information from a remote information source use a reflector for reflecting a laser beam or other light source back to its originating location. A reflector coupled to an information source receives a laser beam from a laser source. A movement of at least one surface of the reflector is controlled to modulate the laser beam, and the modulated laser beam is reflected toward the laser source. The modulated laser beam can be received by a receiver at or near the laser source to detect and decode data embedded in the modulated laser beam.

Patent CA-2551617-A1 (CA)
Inventor: LEE HONG GUAN
IPC: B23K1/005
Filed: 2004-12-23
Abstract: In order to avoid excessive internal stress and micro structure problems inherent with previous fusion welding techniques utilised for component structure fabrication, the present method creates a relatively thin in situ brazing alloy layer upon first and second component edges which are brought together in order to create a component joint. This in situ brazing alloy layer (6, 23, 26) is created by deposition of brazing elements, such as copper or nickel, from an electrical discharge cutting process electrode depletion utilised in order to cut the component edges. A subsequent brazing technique then creates through interstitial migration between that brazing alloy layer and the underlying material substrate of the components a robust component joint. Furthermore, the in situ brazing alloy layer penetrates the respective component cut edge surface to only a limited depth such that the geometric effect is similarly limited, and the properties of the underlying component material structure are maintained.

Title: Interfacial stent and method of maintaining patency of surgical fenestrations
Inventor: SELDEN NATHAN R
IPC: A61F2/90
Filed: 2005-05-09
Abstract: A method according to one embodiment for maintaining patency of an opening inside the human body comprises introducing a radially self-expanding hollow stent into the opening through an endoscope that radially compresses the stent, wherein the stent has enlarged ends and a reduced intermediate portion.  The stent is introduced into the opening such that its intermediate portion extends through the opening and the enlarged ends are positioned outside of the opening. Once deployed, the stent expands such that the enlarged ends of the stent abut against opposing faces of the opening to resist dislodgement of the stent from the opening after expansion. The stent is preferably biodegradable, such that it is eliminated from the surgical site over a period of weeks to months, by which time the patency of the opening is more assured.  The method can be used in combination with, for example, an endoscopie surgical method such as endoscopie third ventriculostomy for treating hydrocephalus of a brain.

Inventor: FENCHL ANDREA
IPC: C09D7/45
Filed: 2005-06-30
Abstract: The invention relates to a mixture composition having dispersing properties, containing copolymers based on unsaturated mono or dicarboxylic acid derivatives and oxyalkylene ethers as component I and water-soluble copolymers and terpolymers containing sulfo groups having an average molecular weight of 50 000 - 20 000 000 g/mol as component II. By combining both components, which can be respectively characterized by four different structural units, it is possible to obtain mixture compositions which can, more particularly, be used as dispersing agents for organic and/or inorganic pigments and fillers, in addition to known applications in the field of structural chemistry. In the field of structural chemistry, the mixture compositions are suitable for use on account of the dispersing properties thereof, particularly in ceramic systems and in water-based painting and coating systems. Independently of the dispersing effect thereof, the described mixture compositions are also excellent solvents, wherein they can be used more particularly as casein substitutes, even in self-levelling gap-filling materials and trowelling compounds by virtue of the stabilizing effect thereof. The inventive mixture composition combines known positive properties of components I and II and can be used in new fields of application, even in the non-structural chemistry field.

Title: Removal of residual acetaldehyde from polyester polymer particles
Inventor: ARMENTROUT RODNEY SCOTT
IPC: C08G63/02
Filed: 2005-08-29
Abstract: In one embodiment, there is provided a process comprising introducing polyester polymer particles containing residual acetaldehyde into a vessel at a temperature within a range of 130 ~C to 195 ~C to form a bed of particles within the vessel, flowing a gas through at least a portion of the particle bed, and withdrawing finished particles from the vessel having a reduced amount of residual acetaldehyde. In this process, it is not necessary to introduce a hot flow of gas at high flow rates otherwise required to heat up cool particles to a temperature sufficient to strip acetaldehyde. Rather, this process provides a benefit in that, if desired, gas introduced into the vessel at low flow rates and low temperatures can nevertheless effectively strip acetaldehyde in a reasonable time because the hot particles quickly heat a the gas to the particle temperature.
