Patent CA-2290019-A1 (CA)
Inventor: BRETT TOM D
IPC: C09J7/22
Filed: 1999-11-18
Abstract: Applied to a substrate such as paper banknotes is a thread which includes a PET carrier layer with release layers on both surfaces of the carrier layer, and a metallic layer outward of one release layer. An adhesive layer lies outward of the metallic layer. When a substrate is brought into contact with the adhesive layer, the result is to bond the metallic layer to the substrate. Following this, the PET  carrier layer is peeled away, leaving the metallic layer bonded to the substrate. An apparatus for accomplishing these steps includes means for bringing the substrate into contact with the adhesive layer, and means for peeling the PET carrier layer away so that it separates from the metallic layer at the adjacent release layer.
Patent CA-2292272-A1 (CA)
Inventor: SONCODI ADRIAN
IPC: H04L47/80
Filed: 1999-12-14
Abstract: A directory-based network comprises user-callable network elements, at least one directory server, and at least one call/process server. The call/process server comprises several decoupled engines including a policy engine which upon system initialization or upon request retrieves a plurality of policy scripts from a directory server and constructs from them an adaptive context-sensitive policy tree.  Upon user call to a network element requesting a service, an agent of the call/process server, which agent is located in the network element, forwards an admission request to the call/process server which executes policy tree in the context of the request and of the current state of the network as reflected in the directory server and in said several decoupled engines of the call/process server. An admission reply is returned to the network element, the contents of which are retained in service-specific control block in the network element and used to control the execution of the request.  Policy scripts can easily be entered, deleted, or modified and a new policy tree built immediately.

Title: Means for and methods of "in-progress" fraud, billing and maintenance in a ss#7 network of high speed data links
Inventor: KARRAS ERNEST
IPC: H04L12/24
Filed: 2000-01-31
Abstract: The invention relates to equipment for call-completion analysis on high speed data links in an SS#7 network. A pyramidal structure service observing system processes data packets from all high speed SS#7 data links communicates directly with other service observing systems in order to create real-time call detail records and statistical reports. The first system which receives an initial address message signal has jurisdiction over a call. If a second service observing system receives data on the same call, that data is forwarded to the first service observing system in real-time so that interim call detail records may be generated while calls are still in- progress. While any suitable and available path may be used to forward the data, a wide area network or a local area network provides the preferred path.

Patent CA-2302714-A1 (CA)
Title: Backflow valve
Inventor: COSCARELLA GABE
IPC: F16K1/22
Filed: 2000-03-24
Abstract: A backflow valve has a closure gate that is pivotally mounted for movement between an open position in which the closure gate is positioned on a plane substantially parallel to a longitudinal axis of a flow passage and a closed position in which the closure gate is positioned transverse to the longitudinal axis. The closure gate has a midsection positioned pivot axis and is unbalanced with greater weight being toward the first end. A rotational stop limits pivotal movement when the closure gate is in the open position. A float is secured to the first end of the closure gate. The greater weight at the first end biases the closure gate by force of gravity against the rotational stop and into the open position. The float causes the closure gate to pivotally move to the closed position in response to liquid rising in the flow passage.

IPC: F41J9/14
Filed: 1998-09-14
Abstract: A simulator for simulating the view of a scene from a predetermined observer station. An image is projected onto an array of back projection screens which are viewed through a concave mirror positioned such that light reflected by the mirror to a predetermined viewing station is collimated. An opaque object is positioned on or immediately in front of the mirror so as to cover a portion of the mirror. This enables portions of a mirror with poor optical qualities, such as occurs adjacent abutting edges of separate sections of the mirror, to be obscured from view so that they do not adversely affect the perceived quality of the viewed image.

Title: Method and apparatus for performing transactions in a stateless web environment which supports a declarative paradigm
Inventor: JACOBS LAWRENCE
IPC: G06F15/00
Filed: 1998-10-27
Abstract: A method and system for processing multiple-request transactions in a stateless environment is provided. A cartridge execution engine (228) intercepts browser messages directed to a cartridge. The cartridge execution engine (228) determines whether the browser messages are associated with transactions. If it is determined that browses messages are associated with transactions, then the cartridge execution engine (228) sends transaction control messages to a transaction manager (606). In addition, the cartridge execution engine (228) sends operation messages to the cartridge. The cartridge then performs the operations specified in the operation messages. In response to the transaction control messages from the cartridge execution engine (228), the transaction manager (506) causes the multiple-request transactions to be either committed or rolled back as an atomic unit of work.

IPC: H04M1/78
Filed: 2000-08-08
Abstract: The present invention provides a filtering ar-rangement for attaching POTS filters to in-building multi-pair telephone cable to form separate POTS and DSL communications channels. In one embodiment, the incoming subscriber loop is disconnected at the NID from the primary pair of the in-building telephone cable and reconnected to an unterminated second pair.      Inside the home or office, preferably inside a tele-phone wall jack junction box, a POTS filter is in-stalled that bridges the second pair to the primary pair. The second pair carries the unfiltered DSL and POTS communications channels. To this pair are con-nected devices that communicate over the DSL channel.      The primary pair now carries the POTS channel only, the DSL channel having been filtered out by the POTS fil-ter.
