Title: Lifetime pulsed neutron/chlorine combination logging tool
Inventor: PITTS ROBERT
IPC: E21B47/12
Filed: 2005-11-18
Abstract: Methods and apparatus for logging a wellbore and determining a presence or absence of a hydrocarbon bearing formation are disclosed. A sonde includes at least two gamma radiation detectors that are utilized for chlorine logging and lifetime logging in combination. Additionally, two detectors of the sonde are spaced axially from each other at different distances from the source to enable determination and compensation for various other parameters such as porosity and water flow velocity.  Appropriate gating of the detectors enables sensing total counts of radiation emitted from adjacent formations and sensing of specific energy ranges of radiation when the formation is bombarded with energy. Signals from the lifetime logging enable adjustment of the chlorine logging for a borehole effect and background radiation. The detectors can include a sheath of a high capture cross-section material that interacts with neutrons to produce gamma radiation to shield the detectors.

Filed: 2004-10-15
Abstract: It is possible to realize a high possibility of obtaining a natural translation as a target language translated from an original language and an appropriate translation of a phrase to be translated in an original sentence.  A translation database contains a plurality of natural sentences of the original language, each consisting of a plurality of words and correlated with a translated sentence of the target language. When a phrase to be translated is specified in the original sentence of the original language, a natural sentence containing the phrase to be translated is searched in the translation database (102). If no natural sentence coincide with the original sentence completely (No in 104), the matching degrees between the natural sentences extracted and the original sentences are calculated. The translation of the natural sentence having the maximum matching degree is displayed (108-112).  When there are a plurality of natural sentences having the maximum matching degree (Yes in 110), a word having a high correlation and existing in the same sentence as the phrase to be translated is judged and a translation of a natural sentence containing the word of high correlation is displayed (114-118). If there is no natural sentence having a word of a high correlation (No in 116), a word which can replace the word in attention in the original sentence is recognized (120-128) and a translation of the natural sentence in which the word in attention is replaced by the alternative word as compared to the original sentence is displayed.

Abstract: In a stroke-variable engine, the position of a center of gravity of a subsidiary connecting rod is determined so that a distance between the position of the center of gravity of the subsidiary connecting rod and an axis of a crankpin is smaller than a distance between a point of connection of a main connecting rod to the subsidiary connecting rod and the position of the center of gravity as well as a distance between a point of connection of a control rod to the subsidiary connecting rod and the position of the center of gravity. Thus, 0.5-order vibration generated in the subsidiary connecting rod is lowered, engine vibration is suppressed, and noise generated with the vibration is suppressed.

Abstract: Preventives for migraine which contain, as the active ingredient, a double antagonist to 5-HT2B and 5-HT7 receptors having selective binding affinities for the 5-HT2B and 5-HT7 receptors. These preventives for migraine show a favorable pharmacological effect compared with the case where an antagonist to 5-HT2B receptor showing a selective binding affinity for the 5-HT2B receptor and an antagonist to 5-HT2B receptor showing a selective binding affinity for the 5-HT7 receptor are each employed alone. Thus, they are useful as drugs showing an excellent effect of preventing migraine and lessened side effects occurring in the existing preventives for migraine.

Title: Method for bioleaching metal containing sulphidic materials
Inventor: SUNDKVIST JAN-ERIC
IPC: C22B3/18
Filed: 2006-09-11
Abstract: The invention relates to a method for a continuous bioleaching of a metal containing sulphidic materials. Such a material in the form of a pulp or slurry is fed to a main circuit, where a bioleaching is performed in one or more stages with a culture of microorganisms which is suitable as regards the ingoing materials. A  material having the ability to promote growth of microorganisms suitable for the bioleaching in the main circuit is fed to a side circuit for the generation of such microorganism. The content from the side circuit is fed to the main circuit in a predetermined flow so that an activity high enough is obtained in the culture in this circuit also at staying times shorter than the critical as should prevail without such an addition. The leaching in the main circuit is, thus, allowed to be controlled of the oxidation degree and temperature, so that a selective oxidation of different ingoing materials is allowed as well as the achievement of a predetermined oxidation ratio of the outgoing material from the main circuit.  A  separated leaching residue from this material is withdrawn having an oxidation ratio suitable for a following metal winning process.

Title: Method, apparatus, system and heat exchanger for increasing the temperature of a substance which is initially in an at least partly solidified state in a container
Inventor: HANSEN ANDERS KROMAND
IPC: F28D7/12
Filed: 2005-04-20
Abstract: One aspect of the present invention relates to a method for increasing the temperature of a substance which is initially in an at least partly solidified state in a container (34), where at least one heat exchanger is arranged in the container. One object is to obtain that the temperature of a substance may be changed relatively fast. This is obtained by having pumping means for displacing the substance, exchanging heat between a heat exchanger and the substance, displacing substance with the pumping means for increased heat exchange between the heat exchanger and the substance, as well as stirring the substance with the pumping means by displacing the substance inside the container. When the substance is displaced, then not only stagnant substance is in contact with the heat exchanger for heat exchange. The amount of substance in contact with the heat exchanger is thereby greatly increased, and the heat transfer is less dependent on thermal conductivity of the substance.
