Abstract: A drilling assembly and a method for directional drilling using the drilling assembly. The drilling assembly comprises a drilling bit, a near bit stabilizer and an adjustable gauge stabilizer. The near bit stabilizer is located a first axial distance from a distal end of the drilling assembly and has a near bit stabilizer gauge which is greater than a nominal drilling assembly gauge. The adjustable gauge stabilizer is located a second axial distance from the distal end, which is greater than the first axial distance, and is adjustable between an extended and retracted gauge. The retracted gauge is less than the near bit stabilizer gauge. A bit drop angle is created between the drilling assembly and the drilling bit, while a stabilizer angle is created between the near bit stabilizer and the adjustable gauge stabilizer.  The combination of the bit drop angle and the stabilizer angle results in a net build angle of the drilling assembly, when the adjustable gauge stabilizer is adjusted to the retracted gauge, and a net drop angle when adjusted to the extended gauge.

Abstract: A system for sonically probing a seabed comprises at least one row (14, 100) of transducers (22, T1, T2, TZ) that each can produce a sonic beam, and a corresponding row of sonic detectors (24, D1, D2). Each transducer is independently energized to produce a narrow sonic beam (40), with resulting seabed or subsea echoes being detected to produce one pixel of a display (60, 80, 90, 150) formed by an X-Y array of pixels, before a next transducer is energized and its echoes are detected to produce another pixel of the display.    When the system detects a large change in echo amplitude at adjacent seabed locations, then scanning at those locations is accentuated by analysis and by additional sonification at different frequencies. The transducers are closely spaced, at a center-to-center distance (G) of typically about 3.5 cm, to provide good horizontal resolution. Each transducer is energized to produce a sonic pulse which, dependent on the application, has a carrier frequency (32) such as 2mHz, 1 mHz, 500kHz or 100kHz. This results in an optimized narrow sonic beam, with each pulse having a duration (A) on the order of 10 to 100 microseconds to produce a modulation frequency on the order of 200kHz to 5Khz, and with each pulse having a high maximum energy to create a wide frequency bandwidth in the seabed.

Title: Method and apparatus for applying laser induced incandescence for the determination of particulate measurements
Inventor: SNELLING DAVID R
IPC: G01N21/71
Filed: 1999-05-20
Granted: 2008-02-12
Abstract: The present invention relates to a method and apparatus for applying laser induced incandescence (LII) to determine a primary particle size of submicron sized particles. The present invention has found that in addition to volume fraction information, particle size can be determined using LII due to the fact that transient cooling is dependent on the diameter of the particle. The ratio of a prompt and a second time integrated measurement from the same laser pulse has been found to be a function of the particle size. A modeling process involves a solution of the differential equations describing the heat/energy transfer of the particle and surrounding gas, including parameters to describe vaporization, heat transfer to the medium, particle heating etc. The solution gives temperature and diameter values for the particles over time. These values are then converted to radiation values using Planck's equation. Thus the technique in accordance with the invention is able to provide a more accurate particle measurement than previous LII techniques, particularly where time averaging is not possible and size measurements must be obtained from a single laser pulse. Simultaneously a particle volume fraction can be obtained in accordance with the invention. Calibration is needed to obtain a quantified volume fraction measurement. In a further embodiment of the present invention, a technique for providing absolute intensity calibration is included in the method.

Granted: 2003-04-08
Abstract: An enhanced network monitor system (30) processes event messages and command response messages from automated banking machines such as ATM terminals (36). Both message types are assigned a single transaction code. The system includes an application program (34) in which the event messages and command response messages are processed in a host computer by parallel message processing regions (52, 54, 56). A modified VTAM communications protocol enables the application to control sequencing of messages generated by the ATM terminals. This enables both event messages and command response messages to be run in a response mode. The transaction processing limit for the parallel message processing regions may be set to a maximum value. The parallel message processing regions run the single transaction repeatedly without reloading which increases the rate at which messages are handled.
