Title: Method for obtaining nmr bound fluid volume using partial polarization
Inventor: KLEINBERG ROBERT L
IPC: G01V3/32
Filed: 1999-05-20
Granted: 2002-02-05
Abstract: The present invention provides methods for determining the bound fluid volume (BFV) of a formation utilizing nuclear magnetic resonance (NMR) techniques in which less than full polarization occurs and in which less than a complete NMR distribution is acquired. The effect of the polarizing static magnetic field is shortened in time by applying a shortened wait time between NMR measurements so that only the bound fluid of the formation is polarized. The shortened wait time is effectuated by early application of the oscillating magnetic field to the formation which, in conjunction with a limited number of refocusing pulses, induces signals in the formation that are measured by the NMR tool. The peak amplitude of these signals corresponds to the BFV. By only polarizing the bound fluid of the formation and only requiring a limited number of refocusing pulses, the NMR methods of the present invention are capable of providing BFV at high logging speeds such as those in excess of 1,800 feet per hour without a substantial degradation of vertical response.      The present invention provides information so that a partial polarization calculation curve in T, lies almost equally between an empirical tapered cutoff curve and a theoretical tapered cutoff curve. Moreover, because no T, information must be acquired, the method is especially suited for logging-while-drilling operations, where the drill string moves uncontrollably during the NMR measurement.

Title: Ultrasonic examination of coated parts
Inventor: WHITE DENNIS A
IPC: G01N29/06
Filed: 1999-06-02
Granted: 2003-08-05
Abstract: When an ultrasonic transducer for detecting discontinuities and/or delaminations in a thin layer of coated material applied to a metal plate or the outside wall or surface of a cast iron dryer cylinder is directed at the coated surface to be inspected at a particular angle, about 10 percent of the single will appear as Harris waves which propagate into the coated test plate at 90 degrees to the surface. This signal which propagates vertically is polarized, with the result that the signal has a greatly improved signal-to-noise ratio. For incident medium of Lucite and employing shear wave refracting in the medium of Lucite, the specific angle is approximately 66 degrees from the vertical for best signal-to-noise ratio. Shear or longitudinal waves can be employed to affect the detection of subsurface defects with the particular angle changing depending on the relation of the velocity of the sound waves in the refracting medium to the velocity of sound waves in the incident medium.

Abstract: When planting plants and similar objects a forest vehicle (1) is used which is provided with automatic planting assemblies (13) mounted at hydraulically controlled arms (11). The vehicle (1) moves slowly forwards and the absolute geographic position thereof is determined by means of satellite signals received on the antenna (15). At the frontmost portion of the vehicle (1) on a movable arm (3) scanning means such as a georadar screen (5) is provided, which transmits radar waves having a suitable wavelength and scans the ground area in front of the vehicle (1). The georadar determines the depth of soil and obstacles to planting such as stones and stumps. From the determinations of the georadar also suitable planting places are determined and the positions thereof are stored. The planting arms (11) and their assemblies (13) are then controlled, so that during the continuous movement of the vehicle forwards the planting assemblies stand still at the determined planting places and there perform planting. Owing to the determination of the soil conditions planting can be made with a high yield and due to the automated procedure using a minimum of man power.

Abstract: An index associated with a database is dynamically processed in an information retrieval system to create a set of questions for use when processing a data inquiry from a user. The index, a structured guide used when searching the database, has different information domains. After one of these domains is selected, a particular order of the index categories within the selected domain is determined, typically by referring to the order lookup table within the index. A script corresponds to the selected domain. Within the script, there are questions corresponding to each index category within the selected domain.  These questions are dynamically used to prompt the user. Only the questions corresponding to active index categories are arranged into the set of questions having a question set order corresponding to the particular order of the index categories. In an iterative process, the first question is identified and used to prompt the user to select a term from a scaled down vocabulary of terms (i.e., only those terms associated with the first question and corresponding first index category). Upon selecting the term, a search of the database is performed by the search engine module based upon the selected term. If there is too much information returned from the search, the next question is identified and the iterative process is repeated.

Title: High performance fan tail heat exchanger
Inventor: TAVASSOLI BAHMAN
IPC: F28F3/04
Filed: 1999-10-27
Granted: 2007-06-05
Abstract: A novel plate fin heat exchanger adapted for high and low velocity fluid flows for dissipating heat from a heat generating component. The heat exchanger comprises an array of fins being affixed to and in thermal communication with a thermally conductive base, wherein the fins are arranged in a fan tail configuration for minimizing flow bypass, and further providing reduced thermal resistance for fluid passing through the fin field. The fins are affixed to and in thermal communication with the base at an acute angle, such that the effective width of the array of fins exceeds the width of the base. The enlarged effective width of the fin array in comparison to conventional heat exchanger provides an increased volume for fluid flow, thereby allowing a greater volume of fluid to enter the fin field and a greater surface area of plate fins for cooling the fluid passing through the heat exchanger. In addition, the heat exchanger comprises a fin density of at least ten fins per inch or greater of base length thereby providing a narrow channel heat exchanger with a fan tail. The aspect ratio of the individual channels between the fins, as compared to parallel fins affixed perpendicular to the base through an extrusion method, generates a reduced pressure drop across the heat exchanger. Accordingly, the heat exchanger of the present invention expands the envelope of cooling performance provided by fluid flow over an array of thermally conductive plates.

Title: Hierarchical schedules for different atm traffic
Inventor: OZVEREN CUNEYT M
IPC: H04L12/56
Filed: 1998-11-17
Granted: 2004-03-30
Abstract: An ATM scheduler in accord with the invention supports multiple transmission traffic types (e.g. CBR, VBR and ABR) for each of a plurality of virtual path connections (VPCs) on an ATM link. The scheduler maintains one or more scheduling tables defining the hierarchy of traffic types and the scheduling for each type of traffic within each virtual path. In each cell transmit time, one VPC is identified as assigned to the opportunity to transmit in the respective cell transmit time. Each virtual path connection supports at least one type of high priority traffic, such as constant bit rate (CBR) traffic, over a plurality of virtual circuit connections. The scheduler determines if there is a high priority service virtual circuit connection (VCC), from among those associated with the identified VPC, and that has been assigned the current cell time slot. If the scheduling device identifies such a VCC, then the scheduler provides the transmit opportunity for that VCC. For example, if the VCC has CBR service, a cell for that VCC is transmitted over the link in the respective cell transmit time. If the VCC has variable bit rate service, a cell is transmitted if there is in fact a cell ready to send over that VCC. Also, during processing for each cell transmit time, the ATM  scheduler accesses a link list. The link list identifies at least one available bit rate (ABR) service type VCC. The link list identified is one associated with the indexed virtual path connection. The ATM scheduler preferably transfers the accessed link list to an ABR work list associated with the indexed VPC. During each respective cell transmit time, if the processing relating to the high priority service(s) did not result in cell transmission in the time slot, the scheduler examines the ABR  work list to identify an ABR service type VCC for which there is a cell that is ready to transmit, and the cell for that circuit is transmitted over the link in the respective cell transmit time.

Abstract: Compositions and methods for introducing a DNA of interest into a genomic target site are provided. In particular, the methods and compositions involve the use of a combination of target sites for two site specific recombinases and expression of a chimeric recobminase with dual target site specificity. Thus, the compositions comprise novel site-specific recombinases with specificities to multiple target sites, and nucleotide sequences and expression cassettes encoding these recombinases or target sites. The methods involve transforming a eukaryotic cell having target sites for the novel recombinase with a DNA of interest that is flanked by corresponding target sites. Expression of the recombinase results in integration of the DNA of interest into the genome of the cell. The compositions and methods of the invention have use in the construction of stably transformed eukaryotic cells, and in particular, plant cells. The methods result in the efficient targeted genomic intergration of DNA by site-specific recombination.
