Filed: 2001-04-30
Granted: 2003-02-04
Abstract: Systems and methods for determining characteristics of geologic formations between conductively lined wellbores. At least one transmitter is axially disposed at a selected depth in a first wellbore and is attached to an external surface of a conductive liner.  At least one receiver is axially disposed at a selected depth in a second wellbore and is attached to an external surface of a conductive liner. Both the transmitter and the receiver are attached to a surface control station. The transmitter generates a first magnetic field, and a formation magnetic field induced by the first magnetic field is detected by the receiver. The detected formation magnetic field is used to determine characteristics of the geologic formations.

Granted: 2009-08-18
Abstract: L'invention concerne un moteur à commutation électronique pour lequel une surveillance s'exerce aussi bien sur le courant d'entraînement (i2) que sur le courant de freinage (i2'). Lorsque le courant d'entraînement est trop élevé, un rapport durée de passage de courant pendant le cycle/durée de cycle est réduit, qui influe sur le courant passant dans le moteur. Lorsque le courant de freinage est trop élevé, ce rapport durée de passage de courant pendant le cycle/durée de cycle est augmenté. A cet effet, il est prévu un circuit analogique comportant deux éléments limiteurs de courant (131, 161), ainsi qu'un circuit dans lequel ces fonctions sont assumées par le logiciel d'un microcontrôleur, de qui permet d'éviter d'avoir à mesurer le courant. Une autre solution consiste à combiner ces deux mesures, une limitation du courant par matériel et une autre, par logiciel intervenant en interaction.

Patent CA-2395478-C (CA)
Inventor: SCHOFIELD KEITH
IPC: C23F11/00
Filed: 2001-02-01
Granted: 2008-11-18
Abstract: An additive to a flame reaction is provided which forms noncorrosive deposit s on cooler metal surfaces which are more stable than Na2SO4 or K2SO4. The additive preferentially combines with the sodium or potassium, and sulfates of these will not be formed. By adding tungsten to the flame, a complex sodium tungstate i s produced on the surface of the cooler metal object in a dense form and corrosion is inhibited. Deposition appears to closely refle ct the relative thermodynamic stabilities of these salts and follows the order Na2WO4 > Na2SO4 > NaCl > Na2CO3. The flame sulfur or chlorine do not remain on the surface in association with the alkali metal. Tungsten can be added in any form desired to the combustio n system. The flame processes all chemical tungsten precursors as equivalent sources of tungsten. Suitable salts that are readil y available are ammonium metatungstate, paratungstate, or tungstate, tungsten hexacarbonyl, tungsten oxides, tungstic acid or any orga no- tungsten compound. The level of tungsten preferably present at an atomic concentration is equal to 1.5 to 2 times that of the sodium in the specific flame environment and possibly a little higher for potassium. The nature of the fuel and possible alkali reduction schemes will control the quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustor. Ta and Nb also appear as possible substitutes for W in the invention.
