Title: X-ray water fraction meter
Inventor: BECKER ARTHUR J
IPC: G01N23/12
Filed: 1997-10-10
Granted: 2008-07-29
Abstract: An x-ray generator provides a continuous bremsstrahlung photon spectrum for determining the water to liquid ratio in a mixture of oil/water/gas flowing through a pipe located a distance from the generator. A plurality of detectors measure photons passing along a beam path from the generator through the fluid. A detector is also provided to monitor the energy distribution of the generator. A time interval for measuring the output of each detector is established such that small changes in the gas to liquid ratio occur during this interval. An energy bin width is selected to provide a linear approximation of the water to liquid ratio. After binning the counts for each detector, a multi-phase flow characteristic such as the water to liquid fraction, liquid density, or liquid fraction along the beam path is determined.

Abstract: An aperture-coupled planar inverted-F antenna (PIFA) including a radiating patch formed on one side of a ground plane and separated therefrom by a first dielectric which may be air, foam or another suitable material. A shorting strip connects a side of the radiating patch to the ground plane at a point corresponding to a dominant mode null, such that the size of the radiating patch may be reduced by a factor of two. A microstrip feedline is arranged on an opposite side of the ground plane and separated therefrom by a second dielectric which may be part of a substrate formed of printed wiring board material. Signals are coupled between the microstrip feedline and the radiating patch via an aperture formed in the ground plane. The use of aperture coupling avoids the excessive cost associated with conventional TEM transmission line or coaxial feeds, while providing improved manufacturability and ease of integration relative to PIFAs with conventional feeds.  Moreover, the aperture coupling provides improved tuning flexibility. For example, a portion of the microstrip feedline may be used as a tuning stub to provide impedance matching on the feedline.

Abstract: Cette invention concerne de nouveaux phosphores d'oxydes à base d'oxydes de gallium dopés, de gallates et de germanates alcalino-terreux qui sont utilisés dans des matériaux d'affichage électroluminescents. Une vive électroluminescence rouge orangé a été obtenue pour la première fois dans des oxydes amorphes et cristallins Ga2O3:Eu.

Une vive émission électroluminescente (EL) a été obtenue à des longueurs d'onde couvrant le spectre visible de 400 à 700 nm, de même qu'une émission infrarouge supérieure à 700 nm avec des pics de spectre caractéristiques des transitions de terres rares. Les films de CaGa2O4 avec 1 mole % de Eu ont permis d'atteindre 22 fL (75 cd/m<2>) à 60 Hz, et possèdent une efficacité maximale de 0,2 lm/w pour les émissions dans le rouge. Une couche mince amorphe de Ca3Ga2O6 avec 2 moles % de Eu a permis d'atteindre 34 fL dans les EL rouges à 60 Hz après avoir été recuit à 600  DEG C. Le SrGa2O4 avec 1 mole % de Eu et 4 moles % de Tb a permis de produire du phosphore "blanc" ayant des émissions rouge, verte et bleue (13 fL à 60 Hz), tandis que le SrGa2O4 avec 8 moles % de Tb a permis de produire du phosphore bleu et vert de 30 fL à 60 Hz. Du Zn2Si0,5Ge0,5O4 contenant du Mn a été vaporisé à l'aide d'un magnétron HF sur des substrats diélectriques en céramique, puis recuit à 700  DEG C et pendant 1 heure dans de l'air ou de l'argon.

Abstract: Disclosed are compositions and a method for amplification of and multiplex detection of molecules of interest involving rolling circle replication. The method is useful for simultaneously detecting multip le specific nucleic acids in a sample with high specificity and sensitivity. The method also has an inherently low level of background signa l. A preferred form of the method consists of an association operation, an amplification operation, and a detection operation. The association operation involves association of one ore more specially designed probe molecules, either wholly or partly nucleic acid, to target molecules of interest. This operation associates the probe molecules to a target molecule present in a sample. The amplification operation is rolling circle replication of circular nucleic acid molecules, termed amplification target circles, that are either a part of, or hybridized to, t he probe molecules. A single round of amplification using rolling circle replication results in a large amplification of the amplification target circles. Following rolling circle replication, the amplified sequences are detected using combinatorial multicolor coding probes that allow separat e, simultaneous, and quantitative detection of multiple different amplified target circles representing multiple different target molecules. Since the amplified product is directly proportional to the amount of target sequence present in a sample, quantitative measurements reliably represent the amount of a target sequence in a sample. Major advantages of this method are that a large number of distinct target molecul es can be detected simultaneously, and that differences in the amounts of the various target molecules in a sample can be accurately quantified. It is also advantageous that the DNA replication step is isothermal, and that signals are strictly quantitative because the amplification reaction is linear and is catalyzed by a highly processive enzyme.

Abstract: An intelligent services network platform (ISN) of a telephone carrier network is equipped with a fax store and forward (FSFS, 10) capable of relaying fax transmission between a customer's fax machine (14) and an international destination. An autodialer (15) associated with the fax machine (14) automatically dials an 800 number designating the FSFS (10). It also automatically dials the preselected destination number and concurrently transmits an identification of the transmitting fax machine. An automatic call distributor (22) in the ISN (12) responds to the 800 number and transfers the fax transmission to an automated response unit (26) which validates the customer's call. Thereafter, the FSFS (10) is enabled to communicate directly with the sending fax machine to receive and store the transmitted fax. The FSFS (10) will subsequently relay the fax transmission, even if repeated attempts are necessary, to the international destination through a bridging switch (20) in the ISN (12) and an international gateway switch (18) connected to the network (16), external of the ISN (12). The FSFS (10) generates confirmations for the customer and billing data.

Abstract: Pellets incorporated with a carbonaceous material of the present invention contain a carbonaceous material and iron ore mainly composed of iron oxide. The maximum fluidity of the carbonaceous material in softening and melting, and the ratio of iron oxide particles of 10 µm or smaller in the iron ore are within the range above a line which connects in turn points A, H and C shown in Fig. 1, including the line. This permits the production of pellets incorporated with a carbonaceous material having excellent thermal conductivity and high strength. Reduction of the pellets incorporated with a carbonaceous material produces reduced iron having high strength after reduction and a low fines ratio with improved productivity.
