Patent CA-2201246-A1 (CA)
Title: Combined liquid transportation and storage system
Inventor: ROBINSON JOHN RODGER
IPC: B60P1/64
Filed: 1997-03-27
Abstract: A transportation system is particularly useful for liquid carrying tanks. Each tank is mounted on a carrier unit and plural carrier units are transported by a single trailer or other vehicle. The trailer has an adjustable height, while each of the tank carrier units has adjustable height legs on its opposite sides. The units are loaded by backing the trailer under the carrier unit with the carrier unit legs extended and the trailer lowered. The trailer is then raised to lift the carrier unit to a transport position and the legs are in turn lifted to the transport position. For unloading, the reverse procedure is adopted, with the carrier unit legs being lowered to the ground and then the trailer being lowered and the trailer being pulled out from under the carrier unit. The carrier units are arranged with an angled base so that when the carrier is pulled out, the carrier unit will tilt forwardly to provide maximum drainage of the tank.

Title: Improvement to a design for an externally drained wall joint
Inventor: TING RAYMOND M L
IPC: E06B7/14
Filed: 1996-02-06
Abstract: This invention relates to exterior building wall systems (10) utilizing multiple wall panels (11) forming horizontal and vertical wall joints (12, 13).

Patent CA-2216429-A1 (CA)
Inventor: KOTLAREK PETER A
IPC: F04C29/02
Filed: 1996-01-30
Abstract: The flow, use, interaction and separation of lubricant and gas flowing through the suction pressure portion of a low-side refrigeration scroll compressor is managed by the use of a drive motor mounting sleeve and a multi-ported frame.  The mounting sleeve and frame provide for the direction of oil to surfaces within the low side of the compressor shell which require lubrication as well as the conduct of suction gas to the scroll compression mechanism in a manner which cools the compressor drive motor yet which maintains the respective flows of oil and suction gas sufficiently separate to ensure that excessive amounts of oil are not conducted out of the compressor in the gas which is compressed thereby. Lubrication is enhanced by the use of a vent passage which opens into a relatively lower pressure region within the suction pressure portion of the compressor shell. The vent induces lift and assists in the delivery of oil, upward and through a gallery in the compressor's drive shaft, to the various surfaces in the upper portion of the compressor which require lubrication.

Title: Dispositif pour deglacer un conducteur sous tension
Inventor: ALLAIRE MARC-ANDRE
IPC: H02G7/16
Filed: 1997-10-24
Abstract: L'invention concerne un dispositif et une méthode pour déglacer un conducteur sous tension. On détecte d'abord la présence de glace dans l'environnement du conducteur à l'aide d'un détecteur et on envoie ensuite, par onde radio, un signal de déclenchement à une source d'impulsions électromagnétiques située à proximité du conducteur. La source produit alors des impulsions électromagnétiques qui circulent dans une ou des paires de fils conducteurs enroulés le long et autour du conducteur sous tension. La force de répulsion électromagnétique que subissent les fils conducteurs lorsqu'un courant circule dans ces derniers les fait bouger, ce qui casse et fait tomber la glace s'étant formée sur le conducteur sous tension.

Title: Method and system for correlating usage data in a distributed architecture
Inventor: LOEB SHOSHANA KORNACKI
IPC: G06Q30/04
Filed: 1996-06-26
Abstract: A method and system for providing a dynamic key in usage records for correlating the usage data records created in a distributed computer or telecommunications network. The dynamic key (22) is a composite structure which captures and reflects the control flow between the service components.  The method has been implemented in a software object that would be resident in each component of a distributed telecommunications system. Specifically, the keys created are dynamic keys comprised of at least two fields (23, 24). The first field (23) is a unique identifier that identifies the session. The second field (24) is a number that identifies the position within the sequence of invoked components that the present component was invoked. This dynamic key is forwarded to the next component (26) and is used as the unique identifier (30) and becomes the first field in the next component's key. These keys allow for correlating usage data records from disparate sources to accomplish such activities as billing and/or fraud detection.

Title: Water jet turn-up apparatus for use in a web winder
Inventor: CASPAR ROMAN C
IPC: B65H19/26
Filed: 1998-01-15
Abstract: A winder for continuously winding a web into roles on successive cores includes a water jet cutting device to effect turn-up of the web onto an empty core. The water jet cutting device has at least one nozzle positioned on the same side as the web as the empty core and upstream of the nip where the empty core meets the driving drum. The water jet nozzle directs a water jet toward the web as the web enters the nip to cut a leading tip which turns up onto the empty core. By directing the water jet against the web on the same side as the empty core the water backsplash at the nip wets the empty core causing the cut tip to turn up onto the empty core. The winder further includes at least one auxiliary nozzle located upstream of the nip on the same side of the web as the empty core for directing a low atomized adhesive fluid stream against the empty core thereby gluing a predetermined strip of the empty core that passes over the leading tip severed from the web causing the leading tip to adhere to the empty core and effect turn-up. Provision is made for the use of two water jet nozzles moving independently of each other to provide a cross cut across the web. When two water jet nozzles are used in this manner, the one auxiliary nozzle providing the low atomized fluid stream is positioned at the lateral center of the empty core to direct the glue onto a center portion of the empty core to assist in turn up.
