Abstract: An apparatus (10) for inclusion in a string having a drill bit located at one end is described. The apparatus (10) comprises a body (20) having a longitudinal axis which is substantially coaxial with the longitudinal axis of the string. A portion (30) of the body (20) has a cross section where the centre of mass of the body (20) on that cross section is offset from the longitudinal axis of the string. A method of reducing the variation of a drill bit from an intended path (1) in a borehole is also described, where the drill bit is coupled to one end of a string having a longitudinal axis. The method comprises the steps of including a body (20) in the string, where a portion of the body (20) has a cross section where the centre of mass of the body (20) on that cross section is offset from the longitudinal axis of the string. The string is inserted into a borehole, and at least the portion of the body (20) is rotated.

IPC: F23Q7/16
Filed: 1998-12-21
Abstract: In a tool for lighting hard to reach natural gas pilots (specifically: furnaces, hot water tanks and barbecues). The microelement is positioned at the top end of the hollow graphite rod, and protected by a safety cage.      The other end of the graphite rod is attached to a handle, which houses the battery pack, and is connected by two wires that extend up the inside of the hollow graphite rod and holds the microelement in place. It is operated manually by depressing a micro switch that is located on the top of the handle. When this switch is depressed it sends a charge to the microelement, producing heat sufficient to light Natural Gas or Liquid Petroleum Gas.      The tool is to be inserted with the microelement held horizontally and placed directly 1/2" above the gas pilot target. After turning the natural gas on to the pilot, the switch on the tool is to be depressed and held until the gas to be lit is ignited, or depressed and held at intervals of no longer than five seconds.

Title: Method for manufacturing a gobo and a gobo produced by the method
Inventor: TANNEMYR MICHAEL
IPC: F21V9/40
Filed: 1997-06-11
Abstract: The present invention relates to a multi-colour gobo for the projection of a multi-colour pattern, and to a method of manufacturing the gobo. On the basis of a multi-colour pattern that is colour-separated into single-colour components, the single-colour components are disposed in parallel planes in the gobo and at least two of these planes are mutually separated by means of a transparent substrate. The gobo may include a plurality of mutually superimposed disc-shaped and transparent substrates (1, 2, 3, 4) and each of the substrates may include a dichroic surface coating so as to form a colour filter. Combinations of the colour filters are able to reproduce the colours of the multi-colour pattern and respective colour-emitting surface coatings present a pattern that coincides with the pattern of corresponding colour components in the multi-colour pattern.

Title: Slagline sleeve for submerged entry nozzle and composition therefor
Inventor: HOOVER DONALD B
IPC: C04B35/66
Filed: 1997-07-08
Abstract: A nozzle or tube which is useful for pouring molten metal, especially aluminum killed molten steel. The nozzle is formed from a blend of doloma and graphite which is bonded together in a carbonized matrix.  Nozzles or tubes made in accordance with this invention have enhanced thermal shock resistance. Furthermore, the nozzles or tubes of this invention resist the formation of aluminum oxide therein when they are used for pouring molten aluminum killed steel. Consequently, these tubes or nozzles can be used in a continuous casting process for a long period of time without having to periodically stop the procedure and change the tubes as they become blocked with aluminum oxide. As a result of the thermal shock resistance, the usual preheating step prior to contacting the nozzle with the molten metal is greatly reduced.

Patent CA-2266831-A1 (CA)
Inventor: AI TOSHISHIGE
IPC: F01D11/02
Filed: 1999-03-24
Abstract: The invention relates to a structure of a seal ring separating surface for a gas turbine, which sets a shape of an end portion in the separation surface to a perpendicular cutting surface and reduces a leaking amount of a sealing air. A seal ring holding ring (1) within a stationary blade fixes brush seals (3, 4) to an upstream side by bolts (5, 6) respectively, so as to form a seal with respect to a rotor disc (69). Further, it fixes and supports a seal ring (2) to a downstream side by a bolt (7) so as to constitute a seal with respect to a seal portion (8) in a disc (69) side. The brush seals (3, 4) and the seal ring (2) are structured such as to have a circular ring shape and a separation construction, and each of the separation pieces has a gap, so that a sealing air leaks to a downward side from an upward side through the gap, however, since the separation piece end portion is formed in a perpendicular cutting surface and a shape of the gap is formed in a bypass passage, a resistance of an air flow passage is increased and a leaking air amount is reduced.

Patent CA-2269876-A1 (CA)
Inventor: HOSIE DAVID G
IPC: E21B21/08
Filed: 1999-04-26
Abstract: Apparatus and methods are disclosed for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure. To allow the drill string to be removed from the casing, the pressure produced by the formation can be bled off and the drill string removed for servicing. The drill string can then be reinserted, the pressure in the casing above the deployment applied to preferably equalize pressure above and below the valve and the drill string run into the hole for further drilling.

Patent CA-2274367-A1 (CA)
Inventor: KROM JAMES A
IPC: C08G81/02
Filed: 1999-06-10
Abstract: A reaction product is prepared by reacting a first polymer having pendant or terminal carboxyl or anhydride groups with a second polymer (e.g. elastomer) having an amine containing terminal group. The second polymer is anionically polymerized. The second polymer is functionalized by reacting the growing anionic chain end with an imine.      Then a protic terminating agent terminates the growing chain end. The first and second polymers are reacted by mixing (desirably above their softening temperatures) and forming a blend with improved physical properties over a blend of similar polymers lacking a reactive amine group.

Abstract: An indwelling urethral catheter sizing system comprises sets of substantially equal length indwelling urethral catheters (14) having various balloon spacings (a, b, c), from bladder balloons (2) to urethral anchoring cuff balloons (36). A method of implanting an indwelling urethral catheter from the sets involves first determining a patient's interballoon urethral segment length, from his bladder to his bulbous urethra immediately downstream of what remains of his prostate gland. A urethral sizing catheter having a balloon spacing corresponding to the interballoon urethral segment length is inserted in the patient to determine the clinical length of the patient's urethral tract from his bladder to his penile meatus. A male indwelling urethral catheter is then chosen from the sets having a balloon spacing corresponding to the patient's interballoon urethral segment length and the clinical length determined with the urethral sizing catheter. The urethral sizing catheter can be used for filling and voiding the bladder.
