Patent CA-2404754-A1 (CA)
Title: Vehicle engine control
Inventor: HENNINGS KENNY L
IPC: F02D41/08
Filed: 2002-09-24
Abstract: An engine control unit, and method of use, uses a power curve or algorithm to pro-actively adjust fuel flow rate to an engine, optionally in combination with a reactive power curve or algorithm, thereby to adjust engine power, in anticipation of changes in loads being imposed on the engine, as well as to respond to engine speed changes. The ECU has a power curve or algorithm stored in memory which responds to certain predetermined operating conditions other than sensed engine speed, by providing a sequence of pro-active change inputs, at predetermined rates of change, in rate of delivery of fuel to the engine combustion chambers, independent of engine speed change, thereby to produce pro-active incremental changes in power output of the engine. Such pro-active incremental power changes are effected in anticipation of changes in load demand on the engine, and correspond generally with expected incrementally progressive changes in load demand on the engine. In preferred embodiments, the power curve or algorithm includes a first upwardly sloping line representing small increment increases in engine power, a second step change increase in engine power, a third downwardly sloping line representing small incremental decreases in engine power, and a fourth relatively greater magnitude step change decrease in engine power. The pro-active change input signals can be combined with reactive change input signals to make respective combination change input signals which take into consideration a variety of operating parameters, including engine speed changes.

Patent CA-2406011-A1 (CA)
Inventor: DALLAS MURRAY L
IPC: E21B33/126
Filed: 2002-09-30
Abstract: A cup tool for use with a mandrel of a wellhead isolation tool has a substantially right-angled stepped shoulder over which an elastomeric sealing element is forced by elevated fluid pressures. A top end of the elastomeric sealing element is inhibited from extrusion past the stepped shoulder during the insertion of the mandrel, thereby reducing the risk of damaging the sealing element before the mandrel is fully inserted through the wellhead. Once the sealing element is exposed to elevated fluid pressures, the top end of the elastomeric sealing element is forced upwardly over the stepped shoulder, and extruded into an annulus between the mandrel and a well casing or production tubing to provide a high-pressure fluid seal.

Abstract: The flush mount breakaway post coupler is a coupler for connecting a post to a ground anchor. The coupler has an upper section and a lower section. The upper section has a socket for receiving a post, a shear section, and an anchor attachment portion for attachment to the lower section. The shear section is hollow and cylindrical and has a groove defined about its exterior so that the wall of the shear section is thin, fracture of the coupler occurring around the annular groove. The lower section is an expansion anchor having a threaded bore for receiving a bolt, the lower section being placed in a tubular ground anchor, or a hole defined in the ground. The socket has a bottom wall, and a cylindrical bore extends through the shear section to a predetermined base in the anchor attachment portion. A bolt hole extends from the base of the bore through the anchor attachment section. A bolt connects the upper and lower sections so that the coupler is wedged into the tubular ground anchor as the bolt is tightened. The coupler is installed with the shear section coplanar with ground level. When the coupler fractures, the socket breaks off, leaving no portion of the coupler above ground, and the remaining annular edge of the shear section and the top surface of the bolt head level with the surface of the ground.
