20090132210 | METHODS, DEVICES AND PROGRAMS FOR TRANSMITTING ROOF AND BUILDING STRUCTURE OF A 3D REPRESENTATION OF A BUILDING ROOF BASED ON SAID STRUCTURE - A technique is provided for transmitting a roof structure for constructing a three-dimensional representation of a building, via a communication network. The technique is based on the transmission of an ordered list of at least two roof models, each including at least: one type of roof; one maximum height parameter of the roof. During construction of the three-dimensional representation of a building, the maximum height parameter of a roof of the list determines a base of the roof in accordance with the list, so that the roof structure corresponds to the ordered superimposition of the roods of the list. | 05-21-2009 |

20080270529 | Method for the Transmission of Content Visualization Data Between a Server and at Least One Client Terminal, Corresponding Terminal and Computer Program - A method and apparatus are provided for transmitting content display data between a server and at least one client terminal, whereby said data are arranged into nodes of a hierarchical tree including at least one parent node and at least one son node, a displayable element being associated with each node. One such method includes the following steps in which: the server transmits a simplified representation of the tree to the client, said representation including, for at least some of the nodes, only information for locating the displayable element in the content to be displayed; the client terminal selects at least one node of interest from the simplified representation as a function of a criterion relating to the distance from the client to the displayable element that is associated with the node of interest in the content to be displayed; and geographical data are transmitted in order to enable said displayable element to be reconstructed for the selected nodes(s) of interest. | 10-30-2008 |

20090202358 | BLADE WITH A COOLING GROOVE FOR A BLADED WHEEL OF A TURBOMACHINE - A blade for a turbomachine bladed wheel, the blade including an airfoil and a platform with at least one air injection passage, the platform including a groove running along the pressure side of the airfoil at least in the vicinity of a downstream portion thereof, and formed between the pressure side and a ridge formed on the platform surface at a short distance from said downstream portion of the pressure side, at least one air injection passage being arranged in the groove. Because of the presence of the groove, the air stream injected via the air injection passage(s) is kept close to the pressure side and thus provides effective cooling of the downstream portion thereof. | 08-13-2009 |
20110194944 | TURBINE BLADE EQUIPPED WITH MEANS OF ADJUSTING ITS COOLING FLUID FLOW RATE - A turbine blade cooled by an automatically variable internal flow of cooling fluid. The blade includes orifices situated under the blade root via which the cooling fluid penetrates, and an adjustment plate including holes situated in register with the orifices, the adjustment plate having a coefficient of expansion that is different from the coefficient of expansion of the blade root. | 08-11-2011 |
20130051980 | HIGH-PRESSURE TURBINE NOZZLE FOR A TURBOJET - A high temperature turbine nozzle with automatic regulation of flow of cooling air passing therethrough. Each of vanes includes a first sleeve drilled with holes and a second sleeve that is engaged in the first sleeve, drilled with corresponding holes, and made of a material possessing a coefficient of expansion different from that of the first sleeve. | 02-28-2013 |
20140105750 | Turbine engine blade - A turbine engine blade having a plurality of blade sections stacked along a radial axis between a root and a tip. Each section extends along a longitudinal axis between a leading edge and a trailing edge, and along a tangential axis between a pressure-side face and a suction-side face. Each section presents a camber line, a deviation defined for each section as the difference between an angle between the tangent to the camber line at the leading edge and the longitudinal axis, and an angle between the tangent to the camber line at the trailing edge and the longitudinal axis. The minimum deviation is at the root of the blade, and the maximum deviation is present at sections situated in the range 0.3 H to 0.8 H, where H is the height of the blade measured from its root to its tip. | 04-17-2014 |
