Title: Method for the reconfiguration of a meshed network
Inventor: MILLET GUY
IPC: H04L12/437
Filed: 1994-03-18
Abstract: ABSTRACT OF THE DISCLOSURE      The  method  relates  to  the  reconfiguration  of meshed networks  for  telecommunications  systems  with time-division multiplexing,  i.e. to a modification of the routing of the signals so that they can be sent with  the  utmost  efficiency  despite  breaks  in  the network. In a network comprising nodes distributed in a loop and, possibly, lateral nodes, when breaks cause the loop to be split into sections, the method consists in using standby lines, if any, to connect the lines to one another and to select these standby lines to join the nodes  into  one  network reconfigured  by  a path without redundancies, i.e. by a path in which the lines are  crossed once  and  only once  in  each direction. Application to networks for telecommunications systems with time-division multiplexing.

IPC: E21B47/04
Filed: 1994-08-03
Abstract: A depth measuring system for a slickline utilized in a well bore operation where the slickline is in a non-slip relationship  with  the  circumference  of  a  calibrated measuring wheel and the revolutions of the wheel  are utilized to provide a first length measurement.   A load cell is provided to measure tension in the slickline so that length elongation of the slickline due to tension can be determined.  A temperature differential determination is made so that corrections in length can be made for the temperature effects.  The temperature differential can be temperature  effects  on  the  measuring  wheel  and/or temperature effects of the slickline in the well bore. The measuring wheel determination of length is algebraically summed with the tension elongation and changes due to temperature to provide a more accurate indication of the depth measurement in the well bore.

IPC: B23B31/22
Filed: 1994-11-01
Abstract: ABSTRACT     A keyless drill chuck apparatus includes a tubular body having a longitudinal bore that can include first and second bore sections.          The first bore section is of a smaller diameter and is closer to the proximal end portion of the drill, that end portion is connected to a tool driver, motor or the like. The second bore section is larger diameter portion that is opened ended. A pair of bearing supports are positioned at the two bore sections. Each of the bearing holders carriers a plurality of conically-shaped bearing members. During use, a drill bit can be placed in either of the bore sections and into engagement with one of the selected sets of bearing. During use, different diameter drill bits can thus be placed as desired in the smaller or larger bore sections and into engagement with the first or second set of bearing. Scalloped portions of the tool body adjacent each of the bores are provided in a corresponding number to the number of bearings. Each of the bearings registers in one of the scalloped portions. During use, rotational energy is transmitted between the tool body and the drill bit-via the conical bearing. Each bearing bites into a scalloped portion and into the drill bit. Because the scalloped portion provides a dished surface, the bite is greater as the drill attempts to rotate relative to the tool body.

Patent CA-2149196-A1 (CA)
Inventor: MCELHINNEY GRAHAM
IPC: G01V3/08
Filed: 1995-05-11
Abstract: A method for locating underground cylindrically symmetrical magnetic sources, particularly boreholes, from magnetic field measurements. The method is based on the shape of magnetic field produced by magnetic materials with cylindrical axes. As the field caused by the magnetic source always points away from or towards its cylindrical axis, lines extended from magnetic field vectors caused by the magnetic source will always pass through the axis. Numerical techniques are used to find the common line to all the extended magnetic field vectors and thus calculate the axis of the magnetic source.
