Patent CA-2152448-A1 (CA)
Title: Method and assembly for coating a moving web
Inventor: KOSKINEN JUKKA
IPC: B05D3/00
Filed: 1995-06-22
Abstract: In air-knife coating the coating mix is applied by means of a suitable application method onto the web (1) to be coated and the coating mix is doctored to desired coating thickness by blowing a sharp air jet (7) discharged from the air knife (6) so as to impinge on the web (1).  Air-knife doctoring occurs most successfully along the upper boundary of the filter-cake layer which forms in the coating after applica-tion.  According to the invention, this phenomenon is utilized for coat weight control by adjusting the distance between the point of application and the point of doctoring.

Title: High performance path allocation system and method for a fiber optic switch for a fiber optic network
Inventor: GRANT ROBERT
IPC: H04B10/291
Filed: 1995-07-31
Abstract: A fiber optic switch (30)  interconnects fiber optic channels  (32)  so  that  a  fiber  optic  network  can  be implemented.   Channel modules  (34) provide ports  (p1-pi) (33) for connection of the fiber optic channels (32). Each channel  module  (34)  has  a  receive  memory  (84)  for temporarily storing incoming data frames from the fiber optic channels (32) associated therewith.  A switch module (36) having a data distribution network (42) interconnects each of  the channel modules  (34)  and permits ultimate connection of  a  source channel  (32)  to a  destination channel  (32).    A path  allocation  system  (50),  which controls the switch module (36), allocates the data paths between the channels (32).  The path allocation system (30) has a scheduler (104) which maintains a destination queue (Qp1-Qpi) for each of the channels (32), a sentry (104) which determines when a new data frame  (11)  is ready to be routed,  and an arbitrator  (123)  which arbitrates port availability and which grants transfer requests proposed by the scheduler (104).

Title: Service Creation Apparatus for a Communications Network
Inventor: WATERS DONALD GEORGE PAUL
IPC: G06F13/00
Filed: 1995-04-21
Abstract: A service creation system for a communications network of the intelligent network type has 3 different levels at which service creation activities can be carried out, these being SCE1, SCE2 and SCE3. The use of separate levels allows access to the service creation system to be kept functionally separate for users having different interests in the network. Hence, features which have to be installed at the network element level for a selected service to be available can be created in SCE1. Marketable service features, which give a view of features in that they encapsulate call handling logic thereof together with support and management descriptions of the feature, can be created in SCE2. Service packages, which permit collection of marketable service features to meet requirements of a service together with service-specific support and management information, can be created in either of SCE2 or SCE3. Profiles, which list the features relevant to a service for a user and provide data slots for the data necessary to each feature, can be provisioned and modified in SCE3.

Patent CA-2206840-A1 (CA)
Title: Mesh interconnected array in a fault-tolerant computer system
Inventor: YOST WILLIAM M
IPC: G06F11/00
Filed: 1997-06-03
Abstract: This invention relates to fault-tolerant computer systems. Bus interface units (BIUs) perform fault detection, identification, and reconfiguration for all information transfers between redundant central processing units (CPUs) and memory or input/output (I/O) in a mesh interconnected array of a computer system. Errors are detected by self-checking within the BIUs, signal parity checks by the BIUs, cross channel comparisons, and mesh transaction assessments. If self implicating errors are detected, the corresponding BIU is shut down, BIU configuration vectors are asserted onto the mesh and a consensus configuration vector is generated. If synchronization or memory bus errors are detected, corresponding error messages are asserted on the mesh and a reconfiguration algorithm is performed in order to generate a consensus configuration vector. Fault identification and mesh reconfiguration for the mesh is performed such that no faulty unit remains active in decision making after reconfiguration, and the number of good units isolated during reconfiguration is minimized.
