Abstract: Un poêle à bois ou autre combustible. Ce dernier comprend un caisson constitué de parois verticales et horizontales, ainsi qu'une chambre de combustion de dimensions inférieures au caisson et disposée dans ce dernier, laquelle est destinée à recevoir un produit combustible notamment du bois, pour engendrer des gaz de combustion. La chambre de combustion est constituée de parois verticales et horizontales inférieure et supérieure. On retrouve un groupe d'espacements verticaux, dont un espacement frontal, un espacement arrière et un espacement latéral, prévus entre au moins trois des parois verticales de la chambre de combustion et des parois verticales correspondantes du caisson. Le poêle comprend au moins deux boîtes de chauffage disposées dans la chambre de combustion, mais scellées par rapport à cette dernière. Les boîtes de chauffage sont espacées l'une au-dessus de l'autre, décalées l'une par rapport à l'autre et s'ouvrent sur les espacements frontal et arrière. Elles sont susceptibles d'être chauffées par la circulation entre elles des gaz de combustion. De l'air frais circule dans les boîtes de chauffage, pour être réchauffé par les gaz de combustion et envoyé ensuite dans la paroi latérale. Le poêle comprend une sortie d'air chaud pratiquée dans la paroi latérale et permettant à l'air chaud de réchauffer l'air ambiant ainsi qu'une sortie d'échappement des gaz de combustion. Ce dispositif permet d'avoir un poêle avec un meilleur rendement que ceux connus à date.

Abstract: ABSTRACT A pattern recognizing system has an input pattern parser for parsing an input pattern to output a candidate graph in which segmenting points in the input pattern are used as nodes.  Categories corresponding to segments defined by the segmenting points are used as respective branches between the segmenting points.  Costs are assigned to the branches.  A candidate graph memory stores data for the candidate graph.  A minimum cost calculator calcul-ates, for all the nodes of the candidate graph, the minimums of the costs of all paths from the nodes to terminal nodes to assign the minimums, as the minimum costs c(n) to the terminal, to the nodes.  A midway path memory stores data of the midway paths from the start node to arbitrary midway nodes.  An estimation calculator calculates an estimation factor f(p,h) for an arbitrary midway path based on the costs assigned to the branches of the paths and the minimum costs assigned to the end node of said midway path.  A best path selector selects the best midway path at an arbitrary instant during recogni-tion from all the midway paths, that are stored in the midway path memory, in accordance with the estimation factor evaluated by the estimation calcula-tor.  A validity judging circuit parses the midway path selected to judge whether or not a category starting corresponding to the midway path forms at least a part of a valid one as a recognition result and to output the midway path or the category string as the recognition result when the category string is valid and when the midway path reached the terminal end of the candidate graph.

Abstract: SYSTEM FOR SIMULTANEOUS GAMMA-GAMMA FORMATION DENSITY LOGGING WHILE DRILLING     ABSTRACT OF THE DISCLOSURE   A system for logging subterranean formations for the determination of formation density by using gamma radiation.  Gamma ray source and detection means are disposed within a housing adapted for positioning within a borehole for the emission and detection of gamma rays propagating through earth formations and borehole drilling fluid.  The gamma ray detection means comprises first and second gamma radiation sensors geometrically disposed within the housing the same longitudinal distance from the gamma ray source and diametrically opposed in a common plane.  A formation matrix density output signal is produced in proportion to the output signal from each of the gamma ray sensors and in conjunction with certain constants established by the geometrical configuration of the sensors relative to the gamma ray source and the bore-hole diameter.  Formation density is determined without regard to the radial position of the logging probe within the borehole in a measuring while drilling mode.
