Patent CA-2270503-A1 (CA)
Inventor: ZEMLAK JIM
IPC: E21B43/26
Filed: 1999-04-29
Abstract: A method of completing and producing hydrocarbons in a well is disclosed.  Ports in the tubing string are blocked so as to prevent fluid communication between the casing string and the tubing string. A fluid column is then created in the tubing string's lower end and a sufficient volume of gas such as nitrogen is added to the fluid column so as to achieve a downhole pressure which exceeds the fracture gradient of the formation. The casing is perforated at the formation so as to fracture the formation. Pressure below the packer is maintained through the use of valve means such as a flapper valve. Sufficient volumes of gas are removed from the well such that the well is in an underbalanced state. The ports in the tubing string are opened so as to release the pressure below the packer and allow it to surge into the tubing string, thus permitting a mixture of hydrocarbons and gas to surge up the tubing string and to the surface.

Title: A method for treating tension-type headache
Inventor: OLESEN JES
IPC: A61K38/08
Filed: 1997-11-04
Abstract: Tension-type headache is treated by interacting with neuronal transmission in relation to pain in connection with headache in a way which prevents or decreases sensitization of second order nociceptive neurons. In particular, treatment is performed by administration of an effective amount of a substance which prevents or decreases central sensitization. Important examples of such substances are substances which interact with glutamate neurotransmission, such as glutamate receptor antagonists, such as NMDA receptor antagonists, such as MK-801 or Amitriptylline or Imipramine or Desipramine or Mirtazaprine or Venlafaxine. Other examples are substances which interact with nitric oxide, such as nitric oxide synthase (NOS) inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA. According to a broader aspect of the invention tension-type headache is treated by administration of substances which are effective in preventing or decreasing pain in connection with tension-type headache, such as the substances mentioned above. An additional aspect of the invention relates to treatment of tension-type headache by administration of substances which substantially inhibit the activity of nitric oxide synthase (NOS), such as NOS inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA.

IPC: F15B7/04
Filed: 1999-10-01
Abstract: An oil circuit of a jack for rising an object to a preset position rapidly, wherein the oil inlet circuit of a hydraulic loop system is improved. An oil channel is installed between the inner oil chamber of the piston rod and the sequential valve. A check valve is installed between the oil channel and the sequential valve. An oil channel is installed between the sequential valve and the check valve for being connected to the inner oil chamber of the piston rod. By changing the positions of the check valve and the oil channel. When in the working conditions of dump load or light load, the sequential valve is closed, thus, the hydraulic oil may enter into the inner oil chamber of the piston rod from the pumping oil chamber through the check valve so that the piston rod will rise rapidly to a still condition. In the still condition, since the check valve closes the oil channel, the sequential valve will open automatically so that the inner oil chamber of the piston rod is communicated to the inner oil reservoir. Thus the inner and outer oil pressures of the oil guiding tube in the piston rod are equal. Thus, no strong still load hydraulic pressure exists in the oil guiding tube within the inner oil chamber of the piston rod. BY this changing, the still load hydraulic pressure of the inner oil reservoir and the inner oil chamber of the piston rod can be adjusted equilibrium by the sequential valve.      Therefore, the problem of breakage of the oil guiding tube of the piston rod and the high cost due to confinement in material are solved.      Moreover, the sequential valve can be located outsides so that the sequential valve is adjustable at outside to a preset actuating pressure.

Title: A technique for detecting leaky points within a network protocol domain
Inventor: NG BILLY C
IPC: H04L29/06
Filed: 2000-02-09
Abstract: A mechanism for allowing a prober to detect and identify leaky points within a network protocol domain utilizes a Probe Boundary Leak (PBL) protocol to propagate a probe message throughout the network protocol domain. Each PBL router that receives the probe message checks for leaky points in the network protocol domain. Any PBL router that detects a leaky point in the network protocol domain sends a negative response message to the prober including a network address for each leaky point detected by the PBL router. A PBL  border router within the network protocol domain being probed sends a positive response message to the prober including a network address for each exit interface supported by the PBL  border router. The prober thereby receives a list of "leaky" network interfaces and a list of "non-leaky" exit interfaces for the network protocol domain.
