Patent CA-2143596-A1 (CA)
Title: Apparatus and method for drilling boreholes
Inventor: DHINDSA JASBIR S
IPC: E21B19/08
Filed: 1995-02-28
Abstract: The present invention provides a drilling system for drilling a borehole. The system contains a drill stem having a drill bit at its one end for drilling the borehole. A draw works containing a drum having a line spooled thereon and coupled to the drill stem controls the upward and down ward motions of the drill stem. A draw works motor is coupled to the draw works for rotating the drum in both the clockwise and counter clock wise directions. A rotary motor is coupled to the drill stem for providing rotational speed to the drill stem. A control circuit controls the operation of the draw works and the rotary motor. The control circuit receives information from various sensors which includes information about the rate of penetration, weight on bit, hook load, and rotational speed of the drill bit. During operation, the control circuit controls the rotation of the draw works to control the upward and downward motions of the drill stem. In one mode the control circuit maintains a. desired rate of penetration and if the weight on bit exceeds an upper limit, it reduces the rate of penetration by reducing the unwinding speed of the drum. In another mode of operation, the control circuit causes the drilling to start at an initial rate of penetration and then starts to vary the rate of penetration according to programmed instructions to optimize the drilling efficiency. In another mode of operation the control circuit causes the drilling to start at initial rotary speed and the weight on bit values and then varies the weight on bit and/or the rotary speed to obtain the combination of these parameters that yields the most efficient drilling of the borehole. If a mud motor is used to drill a borehole, the control circuit may be programmed to control drilling as a function of the differential pressure across the mud motor.

Title: Extended range tdma system
Inventor: UTTING ROSS GRAHAM
IPC: H04B7/26
Filed: 1995-06-07
Abstract: A TDMA radio communication system such as GSM has a limited time period (td) over which the transmission from a mobile station (MS1 .. MS5) can be advanced to allow for the transit time of the signal between the mobile and the base station (BS), and this limits the maximum range of the system to RI. By co-locating a first transceiver (TX1/RX1) operating on a first frequency band(FI) and a second transceiver (TX2/RX2) operating on a second frequency band (FO), and delaying the reception time slots of RX2 by td, the first transceiver can be used for communication up to RI, and the second transceiver can be used for communication for mobiles between RI and RO. Idle mobiles are instructed to camp on FO and RX1 is switched during access request periods to look for access requests on FO.

Patent CA-2171060-A1 (CA)
Inventor: YAMAZAKI KOICHI
IPC: G11B20/10
Filed: 1996-03-05
Abstract: Each information recording track has pre-formatted fore and rear header  sections containing  address  information identifying the track, which permit each of the recording tracks to be accessed from either of the header sections.          A predetermined synchronization signal is pre-formatted in a storing area for each frame having a predetermined data size, so that information can be non-rewritably recorded onto the storing area for a predetermined frame by referring to the  pre-formatted  synchronization  signal.    With  this arrangement, data can be recorded onto a selected information recording track in either of the directions of relative reciprocating  movement  of  the  recording  medium  to  a recording/reproducing head, and thus the recording speed can be increased.   The  arrangement  also allows data to be recorded even when one of the header sections has become unreadable due to some defect of the recording medium, and prevents occurrence of jitters in reproduced signals by allowing data to be recorded accurately at predetermined locations for each of the frames.
