Abstract: The present invention presents a method that effectively provides the near real-time advantage of annular pressure while drilling (APWD) measurements taken during pipe connections that require the mud circulation pumps to be turned off (a "pumps-off" condition). APWD data, such as pressure measurements, are obtained from instruments and related electronics within the bottom-hole assembly (BHA). APWD data can be measured, stored and even processed in the BHA during a pumps-off condition for subsequent processing or communication of a reduced amount of data to the driller at the surface.

Title: Process and apparatus for the manufacture of composite fibrous strand comprising glass fibers
Inventor: MANN HANS GEORG
IPC: D02G3/04
Filed: 2000-04-06
Abstract: A process and apparatus are provided for the manufacture of a composite fibrous strand comprising glass fibers. Glass fibers and an additive fibrous material (e.g., thermoplastic polymeric fibers) are each introduced separately into a substantially rotationally symmetric zone that is closed circumferentially except for a longitudinal introduction locale. The glass fibers and the fibers of the additive fibrous material are subjected to a vortex to form a homogeneous composite fibrous strand.

Title: Atm time stamped queuing
Inventor: PETERSEN LARS-GORAN
IPC: H04L12/56
Filed: 1998-12-08
Abstract: A queuing system (230) stores a package (246) derived from an ATM cell, the package including an internal interface header (IIH) and either an ATM cell payload or an AAL2 packet. The queuing system comprises a queue (312, 320) for storing the package, as well as a processor which executes plural functions. A time stamping function applies a time stamp upon storage of the package in the queue. The time stamping function can apply the time stamp to a package as replacement of the internal interface header. A time stamp checking function uses the time stamp to make a determination whether the tenure of the package in the queue is longer than permissible. The time stamp checking function can make the tenure determination in conjuction with a potential readout of the package from the queue. Alternatively, time stamp checking function can make the tenure determination when invoked by a queue monitoring function which monitors a fill level of the queue (e.g., when a queue fill level exceeds a threshold). A discard function is provided for discarding the package if the tenure of the package in the queue is longer than permissible.
