Patent CA-2231355-A1 (CA)
Inventor: DAOUST BERNARD
IPC: A63C17/14
Filed: 1996-09-06
Abstract: L'invention concerne un système de freinage utilisable pour des patins à roulettes. Le système de frein est monté à l'arrière du patin et il est actionné par le mouvement de la jambe. Contrairement aux modèles classiques, dans lesquels l'actionneur du frein est connecté mécaniquement à la pièce couvrant la cheville du patin, l'invention est conçue pour que l'actionneur soit fixé à la garniture intérieure du patin. Cet agencement permet une transmission plus directe des efforts de freinage, ce qui permet de mieux moduler le freinage. En outre, une meilleure sensation est fournie en retour à l'utilisateur, lui permettant de mieux percevoir l'intensité du freinage appliqué. L'invention concerne également une pièce améliorée couvrant la cheville pour un patin à roulettes et une garniture intérieure améliorée pour celui-ci.

Patent CA-2235196-A1 (CA)
Inventor: COMO CASEY EDWIN
IPC: E21B7/30
Filed: 1998-04-20
Abstract: A method for taking soil samples from horizontal boreholes. A first step involves making a substantially horizontal borehole from an entry pit to an exit pit. A second step involves towing a soil sampling apparatus through the borehole. It is preferred that the apparatus be pulled by the drill string as the drill string is withdrawn from the borehole. By using a soil sampling apparatus that is capable of taking multiple soil samples, all necessary soil sampling along the horizontal borehole may be completed in a single pass.
Patent CA-2236304-A1 (CA)
Title: Sealing arrangement
Inventor: ERSTAD JOSTEIN
IPC: F16L39/04
Filed: 1996-10-31
Abstract: A dynamic sealing arrangement for connectors carrying high pressure fluids such as are used in the oil and gas industry for transferring production fluids from drilling installations to transport vessels. The sealing arrangement comprises a primary and a second U-shaped hydraulically operated sealing ring with open sides facing away from the junction of the connectors in the direction of the fluid leakage path. Barrier fluid under a pressure higher than that of the production fluid is supplied to the chamber between the sealing rings and independently to the open side of the secondary seal. The primary seal thus experiences a pressure differential and is activated. The secondary seal experiences a pressure differential and is activated only if the primary seal fails. Thus the secondary seal does not wear under normal usage of the connectors and is brought into operation automatically, efficiently and without delay when the primary seal is damaged. Repair of the primary seal can then be accomplished at the next routine service avoiding the need to shut down the production line immediately as was the case with known sealing arrangements. Substantial cost savings are achieved.

Patent CA-2240739-A1 (CA)
Inventor: KEATING MARK T
IPC: C12Q1/02
Filed: 1996-12-20
Abstract: One aspect of the invention relates to the identification of the molecular basis of long QT syndrome. More specifically, the invention has identified that minK coassembles with KVQLT1 to form a cardiac potassium channel. Thus, it has been discovered that mutated minK causes long QT syndrome. The analysis of this gene will provide an early diagnosis of subjects with long QT  syndrome. The diagnostic methods comprise analyzing the nucleic acid sequence of the minK gene of an individual to be tested and comparing them with the nucleic acid sequence of the native, non-variant gene. Alternatively, the amino acid sequence of minK may be analyzed for mutations which cause long QT  syndrome. Presymptomatic diagnosis of long QT syndrome will enable practitioners to treat this disorder using existing medical therapy. A second aspect of the invention relates to assays for drugs which interact with the cardiac potassium channel to identify new drugs which are useful for treating or preventing long QT.
Patent CA-2241706-A1 (CA)
Title: Synchronizing a data acquisition device with a host
Inventor: ADDISS ROBERT
IPC: A61B5/0408
Filed: 1998-06-26
Abstract: Apparatus for synchronizing a reference clock signal received from a host system with an A/D converter clock signal generated in a data acquisition pod. The pod includes a decoder responsive to communication received from the host for extracting a host reference signal, and a clock signal source for developing an A/D reference clock signal having a frequency that is different from the frequency of the host reference signal. The pod also includes an A/D converter and a pulse modifying digital phase-locked loop (PLL). The PLL is responsive to the A/D reference clock signal and the host reference signal for developing an A/D clock signal for the A/D converter in which one of its clock periods is periodically modified, thereby locking the rate at which the A/D converter develops samples to the rate at which the host system requests samples. In a preferred embodiment the pod also includes a signal detector for detecting a specified alignment in time of the readiness of the A/D converter to provide a given sample with a host system request for that given sample, and upon such detection, selectively providing an enable signal to the PLL, thereby enabling operation of the PLL and synchronizing the host and pod clock rates, as well as locking in a given alignment the providing to the host of the samples developed by the A/D converter with the host system requests for those samples.
Patent CA-2242283-A1 (CA)
Inventor: WYCECH JOSEPH S
IPC: F16S3/02
Filed: 1998-07-02
Abstract: A method for reinforcing a selected portion of a structural part utilizes a flexible tube having a unexpanded, preferably thermally expandable resin sheath. The sheath may be limited to a selected region along the length of the flexible tube. The flexible tube is inserted through a curved passage and conforms to the geometry of the part to be reinforced. After the portion of the tube having the sheath reaches the desired location, the tube is secured in place. Upon heating, the resin expands to several times its original volume and fills the structural cavity only at that region.

Title: Synchronization in tdma systems in a non-real-time fashion
Inventor: UPADRASTA PRASAD V
IPC: H04J3/06
Filed: 1997-07-10
Abstract: A method and apparatus for synchronization between a base station sub-system (250) and a mobile station (200). The mobile station (200) listens for a message frame number which is generated by the base station sub-system (250). The mobile station (200) includes a mobile frame number counter (280) which tracks the progression of frame numbers. When first powered-up, the mobile frame number counter (280) may not be synchronized with the base station subsystem (250). The frame numbers of the base station sub-system (250) and the mobile frame number counter (280) values are continuously incremented to track the progression of frame numbers in real-time. To effect synchronization, a received and decoded frame number is loaded into the counter (280). Then, a time-lag is calculated which represents the delay inherent in receiving and decoding, within the mobile station and its components, frame numbers from the base station sub-system (250). The time lag is then added to the mobile frame number counter (280) of the mobile station so that the mobile frame number counter is synchronized with the base station sub-system (250).
