Title: System and method for on-line cleaning of black oil heater tubes and delayed coker heater tubes
Inventor: GIBSON WILLIAM C
IPC: B08B9/032
Filed: 2007-06-20
Abstract: A system and method whereby on-line cleaning of black oil heater tubes and delayed coker heater tubes may be effectuated by injecting a high pressure water charge through the tubes during normal process operations so as to prevent tube fouling and heater downtime.  The high pressure water charge begins the on-line cleaning process once it enters the heater tube by undergoing intense boiling and evaporation. The cleaning occurs by two methods - a scrubbing action and a shocking action. The scrubbing action occurs because of the complete turbulence caused by the water charge's intense boiling within the heater tubes. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes.

Title: Method for leaching gold
Inventor: ABE YOSHIFUMI
IPC: C22B3/04
Filed: 2007-08-28
Abstract: In a method for leaching gold from copper sulfides, the sulfide ores are first subjected to leaching of copper, thereby producing a leaching residue having 7.9% or less of the copper content. This leaching residue is mixed with a leach liquor, which contains the chloride ion and ferric ion and has 1.9 or less of pH.   Gold and copper can be effectively leached from the copper sulfide ores.  Ordinarily used oxidizing reagents such as hydrogen peroxide or nitric acid are not used.  The gold, copper and iron can, therefore, be leached in a single process and by using an identical leaching liquor. The rate of gold leaching reaction can be enhanced by the co-presence of either copper or bromide ion or both together with the chloride and iron ion.

Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, the end ones of which expand at least radially when inflated. Connecting passages provide fluid communication between each pair of adjacent chambers. A fluid source is attached to one of the end chambers. The connecting passages are such that the fluid inflates the chambers in a sequence, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The same sequence occurs when the chambers deflate, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The fluid source can either be a fluid supply tube, extending to a supply outside the lumen, or it can be built-in and carried by the device. The device can crawl either along the lumen wall or on an inserted guide wire.

Title: Method, device and program product for estimating properties of a telecommunication tranmission line
Inventor: FERTNER ANTONI
IPC: H04B3/46
Filed: 2005-10-27
Abstract: Determining of transmission properties of a telecommunication transmission line wherein a complex input impedance of the line is first determined (204) from the relationship between a signal sent on the line (200) and a received resulting signal (201). For frequencies for which the absolute value of the propagation constant times line length is less than, the line input impedance can be expressed in terms of line constants (line capacitance, resistance, inductance and conductance) and frequency using a Taylor series expansion.  After truncation of higher order terms and insertion of measured values, the resulting system of equations can be solved and the line constants generated (206), provided that there are at least two frequencies. Furthermore, from the line capacitance and a standard value for line capacitance per km, a line length can be estimated (207).

Title: Splint abutment over osseointegrated implant and compensatory slanted coping
Inventor: CHAVES BRANCA FRAGA DE RESENDE
IPC: A61C8/00
Filed: 2006-11-03
Abstract: The present invention concerns a splint abutment for prosthesis rehabilitation made of various types of materials, attached to an osseointegrated implant.  This splint abutment for implant-supported prosthesis makes it possible to place two prosthetic crowns over a single implant, thus providing better biomechanics, marginal sealing, occlusal stability, aesthetics and oral hygiene maintenance of the dental prosthesis. The biomechanical possibilities of the invention offer greater occlusion stability, since the shape and contour of the splint abutment partially distribute and absorb the mastication forces in a more balanced way to the axial forces. The invention is also concerns the inclination slant, made of the same material of the non-restrictive abutment, to be fit between the implant and the splint abutment, that provides a slant, in order to adjust the position of the "abutment~  according to the correction needs of the rotational and multidirectional angulations of the implants. This invention provides superior resistance of the splint by means of the splint abutment, lasting aesthetics and a reduction in clinical time, assuring greater predictability of the results.

Abstract: L'invention décrit des systèmes et des méthodologies qui permettent de réduire plus facilement les interférences dans un environnement de communication sans fil. Les terminaux utilisent des informations relatives aux interférences fournies par des secteurs avoisinants pour régler la puissance de transmission et pour réduire les interférences. Des points d'accès peuvent fournir deux ensembles ou types d'informations relatives aux interférences. Le premier type d'informations peut être transmis sur une large zone de couverture, ce qui nécessite un surdébit important et limite la vitesse de transmission. Les points d'accès peuvent également fournir un deuxième ensemble ou type d'informations relatives aux interférences sur une zone de couverture plus petite, telle qu'une zone située à proximité de la périphérie du secteur supporté. Ce deuxième type d'informations relatives aux interférences peut être utilisé par des terminaux dont le point d'accès se situe à l'intérieur de l'ensemble actif. Le deuxième ensemble d'informations relatives aux interférences peut être transmis à une vitesse plus élevée que le premier ensemble, les contraintes de surdébit étant réduites. Les terminaux peuvent utiliser les deux ensembles d'informations relatives aux interférences pour régler la puissance de transmission.

Abstract: A multilayer tile for flooring and the like has a cementitious top surface, a lower density intermediate layer preferably incorporating expanded polymeric beads mixed with cement, and a lower layer reinforced by tension-bearing fibers embedded therein. The interface between the top and middle insulative layers may be upwardly domed to reduce the tendency for cracks to form in the bottom surface of the top layer. Channels formed along the edges of such tiles allow insertion of heat transfer tubing to provide a hydronic floor surface. A composite tile may have cementitious top and bottom surfaces with an intermediate lower density layer there between.   Such intermediate layer may be divided into two portions by a water impervious layer that serves as a binder and vapor barrier. Tile panels according to the invention are laid- out on a prepared surface on mortar pads positioned along edges and corners of the tiles, leaving a continuous under air space which may be ventilated to remove moisture, soil gases and radon gas.
