Patent CA-2162515-A1 (CA)
Inventor: COHEN LEONARD GEORGE
IPC: G02B6/24
Filed: 1995-11-09
Abstract: The present invention includes a system for tracing jumpers used in an exchange to cross-connect optical fibers or wires served by the exchange. The system includes an exchange housing receptacles with optically-encoded data associated with eachreceptacle or a group of receptacles. The optically-encoded data for a receptacle(s) uniquely identifies the physical location of the receptacle from any other receptacle in the exchange. Also, this optically-encoded data can include the type of jumper and/or length of the jumper to be used with the receptacle, the correct routing of the jumper through the exchange, the traffic to be carried on the jumper and/or the identity of the physical location of the receptacle to be connected to the other end of the jumper. Likewise, the jumpers each have optically-encoded data formed thereon that uniquely identifies the jumper or jumper end and distinguishes the jumper from any other jumper used in the exchange. The optically-encoded data associated with the jumper can include the type of jumper, the length of the jumper, the proper routing of the jumper through the exchange and/or the traffic to be carried on the jumper. If no jumper is to be connected to a particular receptacle, a cover with optically-encoded data can be attached to a receptacle to indicate that no jumper is connected to the receptacle. The system of this invention also includes a hand-held optical scanner that can be used by an operator to scan the optically-encoded data associated with a receptacle(s) and the optically-encoded data of a jumper(s) connected to the receptacle(s), and transmits the optically-encoded data signals to a computer of the system of this invention. The computer can generate a display of the physical location of a receptacle(s) in association with the identity of the jumper(s) and connected thereto, so that an operator can diagnose misconnections of the jumpers between receptacles in the exchange. Further, the computer can store verification data that can be compared with optically-encoded data signals from scanning with the optical scanner, to determine whether the proper jumper has been connected to a receptacle, whether the jumper is of appropriate type or length for the cross-connection and whether the jumper or receptacle is associated with traffic that is of interest to the operator, for example.

Title: Differential multi-cell intrusion locating cable
Inventor: HARMAN R KEITH
IPC: G08B13/24
Filed: 1994-12-07
Abstract: A transducer cable (5) includes outer conductor (1) inner conductor (2). dielectric (6) therebetween, and a longitudinal passage (4) with sense wire (3) loosely disposed therein extending through said dielectric. Intruder-caused vibration (7) of the cable results in relative movement of the sense wire and outer conductor. causing corresponding sense wire impedance change. A carrier signal (8) transmitted down the inner conductor electromagnetically couples energy to the sense wire. Said impedance change causes reflection of some of the coupled energy, the reflection is sensed by a receiver circuit that in turn produces an indication of intrusion.  The receiver circuit includes a system that digitizes the received signals at successive times that correspond to successive sections of the cable, and produces targe response values for sections of the cable undergoing impedance changes.  Target responses in several adjoining sections are interpolated precisely locate the intruder-caused vibration.

Title: Method of detecting changes in the rate of discharge of fluid from a wellbore
Inventor: BEAUDIN LAURENT
IPC: E21B47/00
Filed: 1996-07-16
Abstract: A method for detecting changes in the rate of discharge of fluid from a well bore. Firstly, providing a flow nipple having a first end, a second end, and a flow line connection extending substantially radially from the flow nipple intermediate the first end and the second end. Secondly, providing a drilling fluid treatment tank. Thirdly, providing a flow line having a first end and a second end. The first end is connected to the flow line connection of the flow nipple and the second end to the drilling fluid treatment tank. This creates a flow path for drilling fluids from the flow nipple along the flow line to the drilling fluid treatment tank. Fourthly, providing an elongate antechamber adjoining one of the flow nipple, the flow line or the drilling fluid treatment tank. The elongate antechamber has a first end and a second end. The first end is positioned in fluid communication with the flow path. The second end extends above the flow path, such that the second end of the elongate antechamber is free of drilling fluid unless a sudden increase in flow rate results in an influx of drilling fluid into the elongate antechamber. Fifthly, positioning a fluid sensing probe in the elongate antechamber. The fluid sensing probe is spaced from and extends toward the first end of the elongate antechamber, such that the fluid sensing probe provides a reading of the level of drilling fluid in the elongate antechamber.

Abstract: The invention proposes a conveyor belt for use in a conveyor installation with atrough zone, where the conveyor belt is supported with rollers (15, 16, 17) or the like on both sides curved towards the top. Both conveyor belt ends (1, 2) are joined together with a hinge joint (4. 5, 6), which is exclusively located in the not curved section of the trough zone of the conveyor belt. The hinge joint containscoupling eyes (20) which are fastened to the conveyor belt and at least one coupling rod (11) in the linkage axle(18), which passes through the intermeshingcoupling eyes.   Such a conveyor belt excels because of the minor wear in the curve area of the conveyor belt during passage through the trough zone. Moreover, it is simply constructed and can be manufactured in an uncomplicated way.
