Abstract: L'invention concerne des inhibiteurs de naphténate à faible dosage, tels qu'un tensioactif ou un hydrotrope, introduits dans des fluides de production prévus pour entrer en contact avec des mélanges d'huile et d'eau, p. ex. dans une formation produisant des hydrocarbures, un équipement de production ou des systèmes de traitement. Des composés inhibiteurs, tels que des esters monophosphoriques et diphosphoriques, possèdent des propriétés tensioactives amenant ces inhibiteurs à s'associer au niveau d'interfaces huile-eau et inhibent des interactions entre des acides organiques dans l'huile et des cations ou complexes cationiques dans l'eau. Ces composés inhibent également l'agrégation de sels de carboxylates d'acides organiques qui se forment lorsque des conditions de pH et de pression se prêtent à l'ionisation des acides organiques. Des inhibiteurs préférés ne forment pas d'émulsions grâce à la formation de structures d'interfaces mixtes instables qui entraînent la coalescence de gouttelettes dispersées. Des dosages de composés inhibiteurs de naphténate inférieurs à 100 ppm peuvent inhiber efficacement des sels de naphténate ou d'autres sels d'acides organiques pouvant former des précipités ou des émulsions pendant la production ou le traitement du pétrole brut.

Inventor: FENNELL MARTIN
IPC: C01F7/147
Filed: 2005-06-17
Abstract: A Bayer liquor is produced by dissolving bauxite in hot caustic soda. The liquor is cooled so that it is supersaturated, and seed crystals of gibbsite are added to the liquor (16). At the same time at least part of the liquor is subjected to intense ultrasonic irradiation (34) such as to cause cavitation, preferably by passing liquor and seed crystals (28) through a recirculation duct (30). The ultrasound increases the proportion of fines by breaking up any crystal agglomerates and also by generating crystal nuclei, and also removes fouling from crystal surfaces. The precipitation process is consequently more effective. If ultrasound is applied when measurements indicate that there are insufficient fines in the liquor, this improves the consistency of the precipitation process.

Abstract: The extracellular domain of the human erythropoietin receptor (EPO binding protein, EBP) bas been expressed and overproduced in E. coli. Control of oxygen levels and pH during high density fermentation allows the production of only the protein variant with the native amino terminus. Methods disclosed permit the efficient recovery of purified EBP which quantitatively binds EPO. The active purified protein competes with membrane associated EPO receptor for binding [125]EPO  and neutralizes EPO dependent stimulation in a cell based proliferation assay. Further, the radioligand equilibrium binding constant for this interaction has been determined by immobilizing EBP on agarose gel via a free cysteine. The EBP of the present invention has many uses including the structural determination of the protein by NMR or crystallography, in drug design and discovery, and as a therapeutic. A  fusion protein of EBP and an immunoglobulin heavy chain was also produced. This protein, termed IBP-Ig, is a preformed dimerization template and is also useful in drug design and discovery methods.

Inventor: KING CAREY
IPC: G09G5/00
Filed: 2005-09-13
Abstract: The encoding and processing of data for many applications can be rendered more tractable when the encoding method can independently manipulate two or more parameters that result, by conjunction, in an accurately posted data value precisely where it is expected. From a data standpoint, this would entail dividing an n-width digital word into separate fractional words and processing the subsets consecutively and independently, where the distinction between these fractional words has an explicit bearing on the information being borne.  For example, an 8-bit word can be decomposed into two 4-bit words, half of which are processed while the transmission source is at full intensity, the other half being processed while the transmission source is at 1/16th intensity, thereby recovering the entire dynamic range of the original 8-bit word while reducing the bandwidth and cycle speed necessary for the transducer to be driven by the input signal.

Abstract: A stimulating needle and catheter system, including components, is provided such that the position of the stimulating needle or the stimulating catheter may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. Use of the needle and catheter system is eased by providing the system to the medical practitioner in a unitary structure. That is, the needle and catheter are connected by a catheter lock. The catheter lock is attached to the hub of the needle and can be actuated to either firmly grip the catheter or allow the catheter to move axially with respect to the lock and needle assembly. Thus, supplying the catheter to the practitioner already locked into the catheter lock allows the practitioner to insert the needle into the patient and, when ready, release the catheter for disposal through the needle into the patient. This and other disclosed features allow the medical practitioner to focus attention on the medical procedure.

Abstract: The invention provides a method and device for inducing a conditioned neural response in a subject. The method comprises detecting spike activity in a first neural site in the subject; and delivering a stimulus pulse to a second neural site in the subject. The stimulus pulse is delivered within the time window for synaptic strengthening following the detecting of a spike.  These two steps, detection and stimulation, are repeated continuously, typically for a day or two. The conditioned neural response is induced when a pattern of neural activity evoked by stimulation at the first neural site emulates a pattern of neural activity evoked by stimulation at the second neural site. The conditioned neural response persists for an extended period of time.
