Patent CA-2279684-A1 (CA)
Title: Method and apparatus for telephone call fraud detection and prevention
Inventor: RYLEY GORDON
IPC: H04M1/67
Filed: 1999-08-05
Abstract: The present disclosure discloses a method and apparatus for detecting and preventing telephone call fraud. The call fraud detector apparatus is connected to the telephone line, and includes a telephone line interface with switch hook. A  parallel set detector indicates to the microcontroller that another device has gone off hook on the telephone line. The microcontroller causes the telephone line interface switch hook to also go off hook in parallel, thereby preventing pulse dialing by the other device. The device may also include a DTMF tone detector and generator to prevent DTMF  dialing on the telephone line. The call fraud detector can provide a visual, audible, and/or tactile indication when unauthorized use of the telephone line occurs, and can be enabled or disabled by an external device. The call fraud detector can log the time and date of each unauthorized call placed on a line, and can also notify the telephone service provider when an unauthorized call is attempted.

Title: Improvements relating to monitoring apparatus for electrical circuits
Inventor: EDWARDS BRYON IVAN
IPC: H02H1/06
Filed: 1999-10-15
Abstract: A trip circuit supervision circuit is disclosed for use in combination with a trip circuit comprising a circuit breaker trip coil connected in a supply line from a supply voltage and a trip relay contact connected in series with the circuit breaker trip coil. The supervision circuit is connected across the relay trip contact and includes a current sensing device.

Thus, changes in the current measured by the current sensing device enable the integrity of the supply voltage to be checked.
Patent CA-2286957-A1 (CA)
Title: Caged slip system and release methods
Inventor: DOANE JAMES C
IPC: E21B33/129
Filed: 1999-10-18
Abstract: An improved cage slip system is disclosed. The cage is constructed so that the cones which actuate the slips extend into the cage openings. The radial extension of the slips is limited so as to retain them if they are extended in an unsupported situation. The cones have a maximum outside dimension equal to the outside dimension of the cage so as to increase the rating of the slips by increasing the bearing area of the cones on the slips. The beneficial features of the cage design are retained while a greater degree of radial expansion of the slips is possible allowing minimization of tool inventory for situations where a lighter wall casing requires further slip extension. The release system allows the lower cones to be driven out from under the lower slips, thus facilitating release of the grip of the lower slips from the casing for extraction of the packer. The mechanical release is functional through the mandrel, whether tension or compression is placed on the mandrel.     Alternative designs are presented for the capture of the lower cone by the cage.

Title: Horizontal reel barge
Inventor: FIBICH MICHAEL JOSEPH
IPC: F16L1/19
Filed: 1999-10-26
Abstract: An apparatus for laying deep water sub sea pipelines either by means of reeled pipe or conventional pipelay ("stock on") is disclosed. The vessel is equipped with a dynamic positioning system that is integrated into the pipelay control system. Both methods of pipe lay utilize a rigid stinger capable of supporting the pipe from near 0 degrees through a departure angle of 90 degrees, simulating a J-lay orientation. The Reel System consists of a storage reel, reel drive system, straightener aligner system, two tensioner systems, three exit rollers, stinger and dynamic positioning system. The conventional pipelay system consists of the above without the storage reel and reel drive system. All pipelay equipment has the capability of leveling winding, thus maintaining a specific pipe profile while the pipe is either being spooled on the quay side or laid on the seabed. The storage reel is modular where it can be removed by either skidding or divided into piece lifts. The apparatus has the ability of interchanging operation modes from reeled pipelay to conventional pipelay without abandoning the pipeline.

Title: Transfer device for lumber packs and other loads
Inventor: RIOUX SYLVAIN
IPC: B65G1/04
Filed: 1999-10-22
Abstract: This transfer device is to be supported by the tines of a forklift and supports a load such as a lumber pack to be transferred to a rack cell which have an anchor bar at its opening. The device comprises an underframe having tine receivers, and a mainframe which is movable with respect to the underframe towards the cell opening and which has hooks to hook onto said anchor bar.      Said mainframe has rollers on which the load is supported. The system is motorized; first, the load remains centered with respect to the underframe when the mainframe is first shifted laterally of the forklift to hook onto the anchor upper bar of a selected rack cell because the frame rollers rotate in a direction opposite to the shifting direction; then the mainframe rollers rotate in the opposite direction to transfer the load into the rack cell.
Patent CA-2289939-A1 (CA)
Title: Detection of retroviral subtypes based upon envelope specific sequences
Inventor: STOYE JONATHAN PAUL
IPC: C07K16/10
Filed: 1998-05-18
Abstract: The present invention is based upon the finding that porcine endogenous retroviruses exist in two different subtypes, which we have termed PERV-A and PERV-B. The differences are reflected in sequence divergence in the envelope genes, and these differences may be used to provide nucleic acid and antibody probes which can distinguish between the two subtypes. This allows patterns of subtype transmission between cells, particularly porcine to human cells, to be monitored.

Title: Wall joint configuration
Inventor: SILL GERALD ALLEN
IPC: B62D33/04
Filed: 2000-09-18
Abstract: The wall joint of the present invention is configured to reduce or eliminate protrusions into the interior of the trailer or container, but does not require coining or stamping of the edges of consecutive sidewall panels. According to some embodiments of the present invention, the wall joint includes two consecutive sidewall panels, each bent to form a main plateau, a spliced plateau and a jogged portion serving as a transition therebetween, with the thickness of the sidewall panel most preferably remaining substantially constant throughout. When two consecutive sidewall panels are positioned next to each other, the spliced plateaus of the two consecutive sidewall panels abut each other and lie in a first plane, while the main plateaus of the two panels preferably lie in another parallel plane. Thus, a region recessed from the main plateaus and surrounding the seam between the two panels is created.

In the contour extraction method and apparatus, from picture image data of a picture image including an image of a body which makes an object of contour extraction, region belonging probabilities with which individual points of the picture image belong to regions are calculated not based on values themselves of the image data but based on attributes of the points of the picture image. Then, the regions to which the individual points of the picture image belong are delimited using the region belonging probabilities, and then a boundary between the regions is extracted as a contour.
Patent CA-2322374-A1 (CA)
Title: Measuring process for individual fibres of cables
Inventor: HERCHENRODER GEORG
IPC: G01M11/00
Filed: 1999-02-01
Abstract: The invention relates to a measuring process for measuring relevant parameters of individual fibres of single-mode and multimode fibres of glass- or plastic-fibre cables. According to said process, the measuring radiation is reflected at the end of the test fibre (3) to the fibre input by means of a mirror, particularly a Schmidt mirror (1), with very high reflectivity (> 99%) and the measurement is carried out at the site of incoupling by means of a combined transmitting and receiving device. This avoids the hitherto necessary spatial separation of the transmitting and receiving stations of the measuring system, particularly in the case of long cables. The Schmidt mirror (1) is connected to the test fibre (3) through the intermediary of a so-called fibre connector (2). The highly reflective mirror coating is applied to the end face of any connector, with the result that the Schmidt connector (4) provided with the mirror coating is connected to the test fibre (3) either directly or through the intermediary of a short glass-fibre cable piece terminated with a standard connector (5) and with the Schmidt mirror connector (4). The use of a thus terminated glass-fibre cable piece has the advantage that the Schmidt mirror connector (4) remains untouched and is protected.
