Title: Use of the combing process for the identification of dna origins of replication
Inventor: BENSIMON AARON
IPC: C12Q1/6804
Filed: 2000-05-29
Granted: 2009-09-01
Abstract: Eukaryotic genomes are duplicated by the activation of multiple bidirectional origins of replication. The replication programs of these cells depend on the temporal and spatial organisation of replication origins throughout the genome. To investigate the replication program in a higher eukaryote, we employed a technique called molecular combing. This technique allows for a quantitative analysis of DNA replication on a genome wide basis. As a model system, Xenopus laevis sperm chromatin were differentially labelled at successive time points after the beginning of DNA synthesis.  Genomic DNA was then extracted and combed on a glass surface. Direct measurements made on the labelled DNA provided a comprehensive analysis of the spatial and temporal organisation of the X. leavis early embryo replication program and revealed that the number of replication origins activated per kilobase increases throughout the period of DNA synthesis.

Title: Digital quasi-rms detector
Inventor: ARMSTRONG STEPHEN WADE
IPC: G10L19/06
Filed: 2002-04-18
Granted: 2007-01-09
Abstract: A digital quasi-RMS detector is provided that approximates the time-varying RMS energy of a signal. The digital quasi-RMS detector rectifies the signal and compares the rectified signal with an estimated present energy value of the audio signal. If the difference between the rectified signal and the estimated present energy value is not greater than zero, then the digital quasi-RMS detector multiplies the rectified signal by a first time constant to generate a first filtered signal and sums the first filter signal with the estimated present energy value to determine the approximate RMS  energy. If the difference between the rectified signal and the estimated present energy is greater than zero, however, then the digital quasi-RMS detector multiplies the rectified signal by a second time constant to generate a second filtered signal and sums the second filtered signal with the estimated present energy value to determine the approximate RMS energy.

Title: Dispositif permettant d'ameliorer les reactions photocatalytiques et photolytiques
Inventor: SPEER SAMUEL E
IPC: B01J19/24
Filed: 2001-03-21
Granted: 2006-06-06
Abstract: L'invention concerne un dispositif permettant d'améliorer les réactions photolytiques et photocatalytiques, comprenant un matériau catalytique enrobé à substrat fixe perméable aux fluides, de préférence, composé soit de tungstène ou de titane pur soit d'alliages de ceux-ci; lequel matériau est oxydé ou anodisé de manière à former une couche d'oxyde de tungstène ou de dioxyde de titane, respectivement, ou un alliage métallique résistant à la corrosion pouvant être enrobé d'un photocatalyseur. Dans un mode de réalisation recommandé, le substrat peut consister en une composition céramique ou polymérique à base de verre présentant des micropores, des voies de passages ou des conduits recevant des agents oxydants, des agents réducteurs et/ou des agents à pH. Le catalyseur consiste en un semiconducteur, tel que TiO2, WO3, Fe2O3, ou en des matériaux à base de titanate adaptés à une utilisation dans le procédé susmentionné; le catalyseur peut être également métallisé. La structure et la configuration du substrat servent chacune à optimiser à la fois la surface de contact photocatalytique et la turbulence du fluide cible dans la zone d'illumination UV maximale de la chambre de réaction, ce qui permet d'améliorer la réactivité photocatalytique. Le substrat consiste généralement en une longueur de maille ou en un matériau de type toile, qui, dans le mode de réalisation recommandé, est plié ou "plissé" en forme d'accordéon. Plusieurs panneaux sont ainsi crées par pliage, chacun de ces panneaux s'adaptant à une ouverture centrale permettant la réception par glissement de la source lumineuse UV. Les bords de chaque ouverture peuvent être éventuellement modifiés à l'aide d'un revêtement spécial qui permet d'empêcher la détérioration de la surface extérieure prédisposée aux rayures de la source UV et de nettoyer la surface par contraction et extension manuelles du substrat en forme d'accordéon. Dans un mode de réalisation différent, un manchon de transmission peut être ménagé entre la surface de la source UV et le dispositif décrit dans cette invention. Le dispositif décrit dans cette invention peut être installé de manière amovible dans des chambres de réaction classiques et plus récentes disponibles dans le commerce sans modification de celles-ci ou sans utilisation de moyens de montage invasifs.

Patent CA-2465411-C (CA)
Inventor: STREATER JAMES R
IPC: E21B41/00
Filed: 2004-04-28
Granted: 2007-07-03
Abstract: An internal, positive engagement lock that locks a tool, such as a hydraulic drilling jar, in the fully open position when the tool is racked back and when tripping in and out of the hole close to the surface. The lock mechanism is spring biased into a locked position that provides a positive engagement between two axially translatable components, thus preventing any actuation of the tool. As the tool is run in the hole, increasing hydrostatic pressure within the tool will cause the locking mechanism to shift to a disengaged position and the tool will operate normally. The spring-biased locking mechanism will return to the locked position as hydrostatic pressure decreases as the tool is retrieved to the surface

Title: Flare stack combustion apparatus and method
Inventor: MASHHOUR MAZEN M
IPC: F23G7/06
Filed: 2002-04-18
Granted: 2008-09-23
Abstract: High-pressure air is discharged in the form of jets moving at a high velocity from nozzles (32) mounted on a ring manifold (30) that encircles the flare stack (10) at a predetermined distance below the flare tip (12), the upper portion of the flare stack being surrounded by an exterior shield (50) that is provided with internal guide vanes (36) at the top portion and perforated with air passages (52) at the bottom portion. The high-velocity air movement in the annular space creates a low pressure zone that in turn induces a larger volume of air from the atmosphere to enter the annular space between the shield and stack where it rises to the flame zone (58), thereby lifting the flame and enhancing turbulent air, fuel and waste gas mixing in the flame zone to minimize or eliminate smoke.

Abstract: A nozzle orifice of a nozzle 1 comprises a tapered segment 16 extending from an elliptical discharge orifice 15 and having a taper angle 0 of 30 to 800, and a large-diameter segment 18 continuing with the tapered segment, and scale on a steel plate is removed by discharging water from the nozzle at a distance between discharge orifice 15 and the steel plate of not more than 600 mm, a pressure of 5 to 30 MPa, and a discharge flow rate of 40 to 200 1/minute. The ratio of the inner diameter of large-diameter segment 18 relative to the minor diameter of the discharge orifice 15 is not less than 3 and less than 7. Also, the discharge flow from the nozzle spreads in a single direction (width direction) within a plane perpendicular to the central axis of the nozzle and the erosion thickness angle is 1.5 to 30 in the direction (thickness direction) perpendicular to the width direction. Such a descaling nozzle enables that scale is removed efficiently at low pressure and/or low flow rate while restraining the cooling of a steel plate.

Title: Provisioning of emergency services in a voice-over-packet environment
Inventor: CRAGO WILLIAM
IPC: H04M11/06
Filed: 2004-11-12
Granted: 2010-03-16
Abstract: The delivery of emergency services to users of a set of communication devices in a packet-switched network is enabled by a method that determines a routing key corresponding to a particular directory number that is associated with a particular communication device, and stores the directory number and the corresponding routing key in a database accessible to a packet switch. The steps of determining and storing are executed during a provisioning phase, in the absence of an emergency call placed by the communication device. The routing key is indicative of routing instructions to be followed by the packet switch upon receipt of a future emergency call placed by the communication device. When the call is received by the packet switch, it will consult the database to obtain the routing key associated with the directory number and send the call as well as the routing key over a path dedicated to emergency calls.
