Title: Thermally stable polyetheramines
Inventor: SANFORD JOE F
IPC: B32B27/28
Filed: 1998-10-13
Abstract: A laminate structure comprises one or more layers of an organic polymer and one or more layers of a hydroxy-functionalized polyetheramine, wherein the hydroxy-functionalized polyetheramine layer is adhered directly to a contiguous organic polymer layer without an adhesive layer therebetween. The hydroxy-functionalized polyetheramine is prepared by reacting (1) a difunctional amine with (2) a diglycidyl ether or diepoxy-functionalized poly(alkylene oxide) under conditions sufficient to cause the amine moieties to react with the epoxy moieties to form a polymer backbone having amine linkages, ether linkages and pendant hydroxyl moieties and then treating the reaction product with a monofunctional nucleophile which is not a primary or secondary amine.
Patent CA-2304748-A1 (CA)
Inventor: HENRY ERIC FRANCIS
IPC: A47F7/00
Filed: 1998-09-21
Abstract: A flow regulator for controlling the flow of material from a container is disclosed, wherein the container includes a container outlet through which the material freely flows when the container outlet is not closed. The flow regulator includes a material passageway having an inlet. The inlet of the material passageway is moved relative to the container between a first position where the inlet of the material passageway is not aligned with the container outlet to prevent the free flow of material between the container and the material passageway and a second position where the inlet of the material passageway is aligned with the container outlet to permit the flow of material between the container and the material passageway. The regulator also includes a regulating flap, configured to substantially cover the container outlet, coupled between the container outlet and the inlet of the material passageway. The regulating flap is moved between a closed position where the flow of material from the container outlet is prevented when the container outlet and the inlet of the material passageway are out of alignment and an open position where the flow of material from the container outlet is permitted when the container outlet and the inlet of the material passageway are substantially aligned. In use, movement of the material passageway relative to the regulating flap controls actuation of the regulating flap between an open and a closed position.

Title: Delayed total release gastrointestinal drug delivery system
Inventor: LERNER E ITZHAK
IPC: A61K9/20
Filed: 1998-10-01
Abstract: A gastrointestinal delivery system is provided. The system comprises a drug in combination with a swellable core material, the core being surrounded by a water-insoluble or relatively water-insoluble coating material in which particulate water-insoluble material is embedded. When the delivery device enters the gastrointestinal tract, the particulate matter takes up liquid, thus forming channels interconnecting the drug-containing core with the outside of the delivery device. Through these channels liquid enters the core which then swells to the point at which the coating is broken. When the integrity of the coating is destroyed, the core then disintegrates immediately releasing all or most of the drug at a specific site. By controlling parameters in the device, such as the core material, carrier material in the coating, and particulate matter, the location of release of the drug can be carefully controlled. Thus, the invention is also directed to a method of using the device for the treatment of disease by the release of drugs in the gastrointestinal tract in a location- and time-dependent manner.

Patent CA-2318909-A1 (CA)
Title: Access to content addressable data over a network
Inventor: CARPENTIER PAUL R
IPC: G06F17/30
Filed: 1999-01-23
Abstract: Access to content addressable data on a network is facilitated using digital information storing devices or data repositories ("silos") (222) that monitor broadcast data requests over the network. A number of silos automatically monitor both data requests and data itself that are broadcast over a network.  The silos selectively store data. Each silo responds to data requests broadcast over the network with data the silo has previously intercepted. A  content addressable file scheme is used to enable the data repositories to reliably identify data being requested. When a data request is received, each silo evaluates whether it has all or a portion of the data being requested and responds to requests when it has the data. Requests for data are implemented by broadcasting a cryptographic hash data identifier of the data file needed.  The data identifier is used by a silo to determine which data to receive and store. A silo includes a network interface (302), a digital asset collector (304), an asset request list (308), asset storage (312), an asset identifier processor (310) and an asset supplier (306). The asset identifier processor computes a cryptographic hash asset identifier for a received asset and compares it to an asset identifier on its asset request list to verify it has the correct asset. A hash of a list of assets is also computed and broadcast over the network (100). When the hash of the list of assets is received by a silo, it places all the assets in its asset request list.
Patent CA-2327177-A1 (CA)
Title: Recipient address masking in computer communications
Inventor: TJONG ANTHONY L
IPC: H04N1/32
Filed: 2000-11-30
Abstract: A messaging system for masking addresses from sending processes. The messaging system maintains a message service profile and a service-address profile. The messaging system accesses recipient data. Sending processes are able to send messages to the messaging system in a form such that each message has an message type and list of recipients. The messaging system is able to determine which of a set of sending services is to be used to send the message, based on the message-service profile. The service-address profile stores information about where in the structure of recipient data the appropriate address for the selected service is located.  The addresses corresponding to the named recipients, for the services determined by the messaging system, can be retrieved by from recipient data. The message system can then provide the recipient address to the appropriate sending services to send the message.

Patent CA-2342524-A1 (CA)
Title: Tension overload indicator
Inventor: MARGETTS WAYNE
IPC: G01L5/04
Filed: 2001-04-03
Abstract: A tension overload indicator includes a housing having a cavity extending along a longitudinal axis between oppositely disposed co-axial first and second apertures for journalling therethrough of a portion of a flexible load-bearing member. The housing has a third aperture having a bore axis orthogonal to the longitudinal axis. A rigid elongate member is slidably journalled in the third aperture between a recessed position wherein a visual warning signal on a distal end of the elongate member is recessed within the; housing and a translated position wherein the warning signal is exposed from the housing. The elongate member extends into the cavity in the recessed position and is releasably locked in the recessed position by a shear member. The flexible load-bearing member is deflected out of co-axial alignment with the longitudinal axis by bending around the inner end of the elongate member. When a tension load in the flexible load-bearing member exceeds a safe load of the flexible load-bearing member corresponding to a shear strength of the elongate member, the flexible load-bearing member straightens in the cavity into alignment with the longitudinal axis so as to urge the elongate member into the translated position, thereby shearing the shear member.
