Title: Apparatus and method for separating components in well fluids
Inventor: HOMAN EDWIN DARYL
IPC: B01D21/00
Filed: 1996-08-28
Granted: 1999-12-07
Abstract: A system for separation of fluids and drill cuttings received from a borehole during an under-balanced drilling procedure.  The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zone, and to provide effective separation and to reduce the detrimental effect due to the presence of the drill cuttings in the returned drill fluids.  In the present invention there is utilized a first stage, high pressure vessel in which a major portion of the gases ad drill cuttings are separated, and a second stage, horizontal low pressure vessel, preferably of greater volume than the high pressure vessel, in which further separating is achieved, including the separate removal of the drilling liquid to be returned to the drill tube.  Because in under-balance drilling, the most serious variation in the pressure of the returning fluid is due to rapid increases in the proportion of gases in the drill fluid, the system of the present invention includes features allowing the control of the operating pressure in the high pressure vessel by way of the flow control of the gases exiting the high pressure vessel while the remaining separating procedure continues to provide effective results.

Granted: 2009-12-15
Abstract: A speech encoding method and apparatus in which an input speech signal is divided in terms of blocks or frames as encoding units and encoded in terms of the encoding units, in which explosive and fricative consonants can be impeccably reproduced, while there is no risk of foreign sound being generated at a transient portion between voiced (V) and unvoiced (UV) portions, so that the speech with high clarity devoid of "stuffed" feeling may be produced. The encoding apparatus includes a first encoding unit 110 for finding residuals of linear predictive coding (LPC) of an input speech signal for performing harmonic coding and a second encoding unit 120 encoding the input speech signal by waveform coding. The first encoding unit 110 and the second encoding unit 120 are used for encoding a voiced (V) portion and an unvoiced (UV) portion of the input signal, respectively. The constitution of a code excited linear prediction (CELP) encoding employing vector quantization by a closed loop search of an optimum vector using an analysis-by-synthesis method is used for the second encoding unit 120.

Granted: 2006-10-17
Abstract: A cutting member for a medical material removal instrument comprises a cutting head having an axis and an elongate drive rod eccentrically attached at a distal end to the cutting head at a location spaced from the axis. The drive rod extends substantially parallel to the axis. The cutting member is used with an introducer sheath or catheter which has a distal end portion inserted into a patient. The cutting head is provided with a cut-out on the proximal side in part for enabling a drawing of material in a proximal direction internally from a patient into a distal end of the sheath upon a partial ejection of the cutting head from the distal end of the sheath during a material removal operation. The material drawn into the sheath is severed in a scissors-type action of the cutting head against the distal end of the sheath upon a drawing of the cutting head via the drive rod into the distal end of the sheath. The cutting head has a maximal transverse cross-section conforming in a close fit to an inner surface of the sheath and is tapered from the maximal transverse cross-section in a proximal direction to facilitate a smooth and unobstructed drawing of the cutting head into the distal end of the sheath and also without damaging the sheath. The cutting head has an at least approximately semicylindrical outer surface located between the maximal transverse cross-section and a most proximal end of the cutting head. The semicylindrical outer surface serves to ensure a locating of the drive rod eccentrically relative to the sheath upon the drawing of the cutting head into the distal end of the sheath. Irrigation is optionally provided to aid in clot removal.

Abstract: L'invention concerne un nouveau procédé et un nouvel appareil de détection non invasive d'un état physiologique ou pathologique. Ce procédé permet d'obtenir une indication sur un état tel que l'ischémie myocardiaque ou les apnées du sommeil par la détection de la réponse du tonus artériel périphérique à cet état. Un champ de pression statique est appliqué autour de la partie distale d'un doigt du sujet, ce champ étant suffisant pour (a) prévenir sensiblement l'accumulation veineuse, (b) le reflux veineux incontrôlé (c) réduire partiellement la tension des parois des artères, mais sans obstruer les artères, pour chaque extrémité distale. Des variations du tonus artériel périphérique et des variations de volume correspondantes de la partie distale du doigt sont détectées afin de permettre le contrôle ou la détection d'un état physiologique ou pathologique. L'appareil comprend une sonde, se présentant sous la forme d'un tube s'adaptant sur le doigt du patient, qui est conçue pour appliquer une pression suivant les contraintes (a)-(c) précitées, un manchon compressif contigu s'étendant dans la limite de ce champ de pression. Cette sonde comprend ou est associée à un capteur/transducteur de signaux destiné à surveiller les variations du tonus artériel. Ce procédé et ce dispositif sont notamment appropriés pour détecter l'ischémie myocardiaque et les apnées du sommeil, et surveiller les phases du sommeil, et pour mesurer en continu la pression sanguine. L'invention concerne également un nouveau procédé d'étalonnage des caractéristiques de conformité des réseaux vasculaires mesurés dans lesquels est modulée la pression intravasculaire, ce qui est utile pour effectuer les mesures de pression sanguine.
