Patent number: 6819008Abstract: A method for operating a switched reluctance electrical generator in a manner that is highly efficient involves initially performing a mapping technique to obtain data relating to all of the possible operating conditions of the generator system that generate the desired output power. This mapping technique can be performed empirically or by computer simulation. Then, the effective phase currents supplied to the windings on the stator are measured or calculated. Next, the optimum conduction angles can be selected as those turn-on angles and turn-off angles that occur using the smallest effective phase currents supplied to the windings on the stator. Lastly, the generator system is operated using the selected optimum turn-on and turn-off angles. If desired, a feedback loop can be provided for comparing the actual output power that is generated by the generator system with a desired reference output power level to insure that such actual output power is maintained at or near the desired output power.Type: GrantFiled: August 7, 2002Date of Patent: November 16, 2004Assignee: Dana CorporationInventors: Martin Kaplan, James M.

Patent number: 6719498Abstract: A slope stabilizer in which both a ground anchorage and a soil nail are located in a single borehole. The ground anchorage includes a plurality of ground anchorages, each including a tensile member bonded to the bore grout along substantially its whole length. The slope stabilizer has the advantage of allowing the ground to be pre-stressed using the ground anchorages. However, an active zone of the ground is also stabilized by the soil nail, which allows a lighter facing structure to be used than is normal with ground anchorages. Economy of operations is obtained, as a number of items are included in a single borehole.Type: GrantFiled: July 19, 2002Date of Patent: April 13, 2004Assignee: Keller LimitedInventor: Anthony Donald Barley
