Title: Traceable well cement compositions and methods
Inventor: BUCHANAN RONNIE J
IPC: E21B47/10
Filed: 1996-12-13
Abstract: The present invention provides improved traceable well cement compositions and methods.  The compositions are basically comprised of hydraulic  cement,  sufficient water to  form a pumpable slurry and a normally non-radioactive tracer compound which becomes radioactive and emits detectible rays over a relatively short time period when exposed to neutrons.   The methods of the invention relate to cementing a zone in a well and subsequently detecting the subterranean location of the cement composition therein.  A traceable well cement composition of the invention is formed and introduced into a subterranean zone to be cemented.  Neutrons are then emitted from a source in the well so that the tracer compound emits detectible rays, the rays are detected and the location of the cement composition in the well is determined.

Title: Access valve devices their use in separation apparatus, and corresponding methods
Inventor: HOFMANN MARTIN JOHN
IPC: G01N30/20
Filed: 1995-10-03
Abstract: An access valve suitable for controlling fluid flow into and out of a chromatography column has a central axially movable probe with a head (71) acting as a spool valve in a barrel (6). Axial movement of the probe adjusts the valve between a fully open condition, in which both a first conduit (73) extending through the probe and a second conduit (51) defined around the probe are open to the column interior, a partly open condition in which a second sealing land (76) on the probe closes the second conduit (51), and a fully closed position in which both conduits are closed. The three positions are useful for packing and unpacking chromatography media into and from the column. In the closed condition of the valve, the first and second conduits (73, 51) communicate with one another so that the valve interior can be cleaned while the column is operating.

Title: Jet engine fan noise reduction system utilizing electro-pneumatic transducers
Inventor: OLSEN RONALD F
IPC: G10K11/178
Filed: 1995-10-12
Abstract: A jet engine fan noise reduction system.     The noise reduction system includes active noise control to suppress fan (15) tone noise of an airplane flyover noise signature. The active noise control includes microphones (1, 11) with acoustic transducers upstream and downstream of the engine fan (15) and fan exit guide vane (16) stage to sense control system errors. Control signals are derived from the fan angular speed or blade passing frequency and the error signal sensed by the acoustic transducers. The control output signals actuate (modulate) air control valves (45) on each side of the fan stage to direct conditioned (pressure and temperature regulated) high pressure primary air flow, thereby producing acoustic cancelling of fan tone noise.
