Title: Method and apparatus for sealing and transferring force in a wellbore
Inventor: VAN BUSKIRK RICHARD GLENN
IPC: E21B33/13
Filed: 1996-05-16
Abstract: A wellbore (1) is at least partially obstructed with a partition or obstruction member (5). A fluid slurry of an aggregate mixture of particulate matter is pumped into the wellbore adjacent the partition or obstruction member. The aggregate mixture of particulate material contains at least one component of particulate material, and each of the at least one particulate material components has an average discrete particle dimension different from that of the other particulate material components. Fluid pressure then is applied to the aggregate material and fluid is drained from the aggregate material through a fluid drainage passage in the partition or obstruction member. The fluid pressure and drainage of fluid from the aggregate mixture combined to compact the aggregate mixture into a substantially solid, load-bearing, force-transferring, substantially fluid-impermeable plug member (11), which seals a first wellbore region from fluid flow communication with a second wellbore region. The plug member is easily removed from the wellbore by directing a high-pressure fluid stream toward the plug member, thereby dissolving or disintegrating the particulate material of the plug member into a fluid slurry, which may be circulated out of or suctioned from the wellbore.

Title: Learning autopilot
Inventor: STROHACKER FRED M
IPC: G05D1/10
Filed: 1995-10-30
Abstract: A learning autopilot for a vehicle provides the capability to command complex maneuvers or maneuver the vehicle when control by its ground station is not possible. A memory is used during a piloted rehearsal mission and position and time information for the aircraft is stored in the memory. This memory is incorporated into the vehicle control system, and during automatic operation of the aircraft, the recorded position and relative time information is retrieved and compared against position and relative time information occurring during automatic flight. The difference between the recorded information and the actual flight information is used to generate error signals which are converted to command signals for the vehicle. Maneuvers which were initiated and completed by the pilot during the rehearsal mission are then repeated during the automatic flight from the flight information stored in the memory.

Patent CA-2231222-A1 (CA)
Title: Multi-photon laser microscopy
Inventor: WEBB WATT W
IPC: G01N33/483
Filed: 1996-09-18
Abstract: A laser scanning micrsocope (10) produces molecular excitation in a target material (14) by simultaneous absorption of three or more photons to thereby provide intrinsic three-dimensional resolution.  Fluorophores having single photon absorption in the short (ultraviolet or visible) wavelength range are excited by a beam (16) of strongly focused subpicosecond pulses of laser light of relatively long (red or infrared) wavelength range. The fluorophores absorb at about one third, one fourth or even smaller fraction of the laser wavelength to produce fluoroscent images of living cells and other microscopic objects. The fluoroscent emission from the fluorophores increases cubicly, quarticly or even higher power law with the excitation intensity so that by focusing the laser light, fluorescence as well as photobleaching are confined to the vicinity of the focal plane. This feature provides depth of field resolution comparable to that produced by confocal laser scanning microscopes, and in addition reduces photobleaching and phototoxicity.
