Title: A soft switched pwm ac to dc converter with gate array logic control
Inventor: CYR JEAN-MARC
IPC: H02M7/04
Filed: 1997-09-26
Granted: 2003-12-30
Abstract: A soft switched PWM AC to DC power converter for a DC power supply is disclosed.  The power supply includes a power factor corrector  (PFC)  converter with a power boost topology,  a DC/DC converter with a forward topology and a fly-back converter which serves as an auxiliary power supply for the controller components.   The three converters are synchronized by a gate array logic (GAL) IC to minimize EMI noise.  The GAL also conditions the PWM for the PFC and the DC/DC converter to provide very precise switching control.          Synchronizing and PWM timing signals are derived by the GAL using a high-speed clock signal that is input to the GAL as a data input.  The clock signal is repeatedly divided using synchronous division to yield a digital monostable timing signal  that  enables  very  precise  control  of  converter switches.

Title: Subassembly electrical isolation connector for drill rod
Inventor: CAMWELL PAUL L
IPC: E21B47/12
Filed: 1998-03-16
Granted: 2004-09-28
Abstract: A subassembly electrical isolation connector for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations electrically isolates the inner connection of the drill rods.  The connector comprises a housing, a mandrel, a connector for connecting the housing to a first tubular drill rod, a connector for connecting a mandrel to a second tubular drill rod and a device for interconnecting the housing and the mandrel in a manner to electrically isolate the housing from the mandrel with the housing overlapping at least a portion of the mandrel. The housing has an isolated end which is electrically isolated from the mandrel and the connector for connecting the mandrel to a second tubular drill rod. The mandrel has a conical tapered body portion which is located within the housing and the housing has a corresponding conical tapered inner surface. The conical taper for the housing and the mandrel converge inwardly away from the housing isolated end. Such arrangement provides enhanced strength to resist bending moments along the connector and resisting drilling forces. The tapered surfaces provide for a connector retrieval in the event of connector break-up due to excessive drilling forces. The subassembly is particularly useful in applications involving directional drilling in earth formations, particularly oil well drilling, the drilling of bore holes under river beds and other obstacles and earth formations, bore hole inspection systems, directional drilling in respect of geothermal wells, ventilation shaft drilling in mineral mining formation and the like.

Abstract: Detector nucleic acids are employed for detection of nucleic acid target sequences by fluorescence quenching mechanisms. The detector nucleic acid comprises at least two oligonucleotides and is partially single-stranded and partially double-stranded. One of the two dyes of a donor/acceptor dye pair is linked to the first oligonucleotide and the other is linked to a second oligonucleotide such that they are in close spatial proximity when the first and second oligonucleotides are base-paired and donor fluorescence is quenched. A single second oligonucleotide may be hybridized to the first oligonucleotide or multiple second oligonucleotides may be hybridized to the first oligonucleotide and to each other, forming a junction structure comprising multiple donor/acceptor dye pairs. The detector oligonucleotide retains its partially single-stranded and partially double-stranded conformation in the absence of target. In the presence of target, however, the second oligonucleotide(s) of the detector nucleic acid is/are completely or partially displaced from the first, increasing the distance between the donor and acceptor dyes and causing a change in fluorescence which may be detected as an indication of the presence of the target sequence.

Abstract: The total porosity is calculated by summing over the effective porosity and the CBW porosity. With the correction described in this patent, an overcall of the total porosity from some part of the clay bound water signal being counted twice is avoided. The effect will be more significant in shaley sand where CBW porosity is abundant. The correct T2 distribution is essential to BVI and SBVI estimation. The same data correction concept can be applied to make a meaningful comparison of logs or laboratory core NMR data that are obtained with different sampling periods TE.

Abstract: Programme utilisant un procédé électronique de balayage du document légal non classé aux fins de renvois. Les renvois sont dépouillés et mis aux normes. Un logiciel d'assortiment permet alors de comparer les renvois dépouillés et normalisés aux renvois de référence dans le fichier de commande des appariements. Pour chaque appariement effectif, chaque nouvelle classification avec laquelle le renvoi de référence a été associé est enregistrée en mémoire avec une marque numérique de classification initiale de zéro, et les résultats antérieurs de classification sont incrémentés dans ladite marque de classification. Des règles heuristiques simples basées sur les connaissances et l'expérience de légistes sont utilisées pour incrémenter les marques de classification basées sur les renvois de références appariées. Après que tous les renvois ont été comparés aux renvois de référence, toutes les marques de classification sont comparées à une valeur seuil. Si la marque de classification d'une classification particulière est plus grand ou égal à la valeur seuil, le système introduit dans le document légal au moyen d'un programme d'écriture une clé de classification et une clé hiérarchique de document se rapportant à la classification.
