Patent CA-2159806-A1 (CA)
Inventor: FLOYD JOHN MILLICE
IPC: A62D101/22
Filed: 1994-04-05
Abstract: A process for treating carbon-containing material contaminated with toxic elements utilises smelting of the material in a top-submerged lancing reactor. The material has its carbon content present as elemental or free carbon. Smelting is conducted so as to form, or in the presence of, a fluid slag. In the course of smelting, free-oxygen-containing gas is injected into the slag by top-submerged injection, to combust the carbon content of the material. Volatilizable toxic elements are discharged in reactor off-gas, while noa-volatilizable elements are substantially fully incorporated into the slag.

Patent CA-2161987-A1 (CA)
Title: Optical fiber encapsulation techniques
Inventor: BURACK JOHN JOSEPH
IPC: G02B6/00
Filed: 1995-11-02
Abstract: A method for encapsulating optical fibers (26, FIG. 2) comprises the steps of bonding optical fiber to a first surface of a rigid flat member (17) and placing the flat member in a substantially air-tight chamber (10, FIG. 1). An encapsulating sheet(13) is located in the air-tight chamber, such that it faces the flat member. The air pressure on the flat member is then made to be significantly lower than the air pressure on the encapsulating sheet, thereby to cause the encapsulating sheet (13) to press against the flat member (17, FIG. 3). The encapsulating sheet is made of aflexible flame-resistant material that maintains its structural integrity and does not melt or ignite at temperatures of at least two hundred degrees Centigrade. For example, the encapsulating sheet may be of Kapton (a trademark), doped Mylar (a trademark) or aluminum foil. The encapsulating sheet (13) is bonded to the flat member by an adhesive (31, FIG. 2) so that, after the sheet has been pressed against the optical fibers (26), it thereafter permanently supports each optical fiber in its assigned position.

Title: A method for admission control and routing by allocating network resources in network nodes
Inventor: ELWALID ANWAR
IPC: H04L12/56
Filed: 1996-07-15
Abstract: A method regulates the admission control of, and requests for routing of, virtual circuits in a network by determining network resource requirements for the virtual circuits.  In particular, the network resource requirements are based on a set of parameters used to control the flow of information from a communications device onto the virtual cirucit.  The requirements for network resources typically include buffer space requirements in network nodes and bandwidth requirements in networklinks, and the parameter used to control the flow of information are those associated with an access regulator.  The network resource determination is made for the case where lossless performance in the network is required and in the case where statistical multiplexing with limited loss is allowed. Both constant bit rate and variable bit rate information is considered.
Patent CA-2181440-A1 (CA)
Title: Using lasers to fabricate coatings on substrates
Inventor: MISTRY PRAVIN
IPC: C30B25/10
Filed: 1995-01-17
Abstract: Laser energy is directed at a substrate to mobilize, vaporize and react a constituent (primary) element (e.g., carbon) contained within the substrate, so as to modify the composition (e.g., crystalline structure) of the constituent element, and to diffuse the modified constituent back into the substrate, as an adjunct to fabricating a coating (e.g., diamond or diamondlike carbon) on the surface of the substrate. This creates a conversion zone immediately beneath the substrate, which transitions metallurgically from the composition of the underlying substrate to a composition of the coating being fabricated on the surface of the substrate, which results in diffusion bonding of the coating to the substrate. Additional (secondary) similar (e.g., carbon) or dissimilar elements may be introduced in a reaction zone on and above the surface of the substrate to augment the fabrication of and to determine the composition of the coating. The laser energy is provided by a combination of an excimer laser, and Nd: YAG laser and a CO2 laser, the output beams of which are preferably directed through a nozzle delivering the secondary element to the reaction zone. The reaction zone is shielded by an inert (non-reactive) shielding gas (e.g., N2) delivered through the nozzle. A flat plasma is created by the lasers, constituent element and secondary element on the surface of the substrate and the flat plasma optionally extends around the edges of the substrate to fabricate a coating thereon. Pre-treatment and coating fabrication can be performed in conjunction with one another (insitu). Alternatively, a substrate can be pre-treated to characterize its surface for subsequent coating. In either case, certain advantageous metallurgical changes are induced in the substrate due to the pre-treatment. The processes (pre-treatment and coating fabrication) are suitably performed in ambient, without preheating the substrate and without a vacuum. Substrates of numerous geometries, sizes and shapes, such as flat cutting tool inserts as well as round cutting tools, are readily coated in this manner. The lasers are directed at any suitable angle (including coaxial) relative to the substrate and/or the plasma.
