Patent CA-2340044-A1 (CA)
Inventor: SCRIVEN ROGER L
IPC: C03C17/00
Filed: 1999-08-11
Abstract: A copper containing component and a manganese containing component are applied onto the surface of a substrate to form a coating having a selected ratio of copper to manganese to form a desired color. Further, color shifting of a multi-component coating upon subsequent heat treatment is minimized or prevented by determining the most mobile species in the coating and then placing a concentration gradient layer of an oxide of that mobile species between the substrate and the coating. Upon subsequent heat treatment, the mobile species in the gradient layer diffuses into the substrate more readily than the mobile species in the coating. Still further, color shifting due to heating, e.g. tempering operations, is minimized by adding calcium to an FeOx system to prevent darkening of the film after heating. An apparatus for forming a graduated coating on a substrate includes o coating station positioned along a conveyor. The coating station includes a first coating dispenser pivotally mounted on a first support and at least one exhaust hood.  The first coating dispenser is positioned such that an axis through the delivery end of the first coating dispenser subtends the substrate at a predetermined angle.

Patent CA-2346514-A1 (CA)
Inventor: NORVELL THEODORE S
IPC: G06F17/50
Filed: 2001-05-04
Abstract: Two new ways are presented to implement ordinary programs with logic gates with a new method of timing within circuits, and a new method of circuit verification.  Application-specific circuit design can be done by using a standard programming language to describe the function that a circuit is intended to perform, rather than by describing a circuit that is intended to perform that function. The circuits are produced automatically;  they behave according to the programs, and have the same structure as the programs. In both methods, for timing local delays are used. A formal semantics is given for both programs and circuits in order to prove the correctness of the associated circuits.

Title: System and method for transporting multiple protocol formats in a lightwave communication network
Inventor: LAWRENCE VICTOR B
IPC: H04L12/56
Filed: 2001-06-19
Abstract: A system and method are described for transporting a heterogeneous mix of traffic having one or more protocol formats and supplied by one or more users or sub-networks in a communication network. Heterogeneous traffic is packaged into digital containers that are routed and processed in network nodes interconnecting the users or sub-networks. A digital container includes a frame structure comprising a header section and a payload section, wherein the header section includes information for routing the digital container and for identifying the type of payload being carried. The payload section is capable of carrying one or more different types of traffic formatted according to one or more protocols, e.g., IP, ATM, etc. As such, traffic supplied by one user node may comprise ATM cells, another may comprise IP packets, and so on. Traffic from each of the user nodes is combined in digital containers at a network node for transport over a core transport network via other network nodes. Because processing and routing of digital containers occurs at the network node level, a digital container is therefore assembled or otherwise formed so that the payload contents only include traffic for user nodes serviced by the same network node. Processing of the individual payload remains a user or sub-network responsibility while the less processor-intensive routing and processing of digital containers occurs at the network node level.
