Granted: 2009-11-03
Abstract: Un épurateur des gaz d'échappement comprend une série de passages à contre-courant emboîtés, y compris un plénum chaud ayant une coupe en étoile. Les gaz d'échappement provenant du plénum chaud passent par un bain liquide et s'écoulent dans une direction opposée à travers un réseau incliné d'ailettes de mélangeage espacées, plates et chevauchantes, ce qui produit une turbulence dans les gaz d'échappement et permet la formation des microbulles finement dispersées, qui améliorent la dilution des polluants gazeux dans le liquide d'épuration. Des ailettes antibuée séparent les liquides entraînés des gaz d'échappement. Le plénum chaud réchauffe les gaz d'échappement et les porte à un niveau insaturé. L'épurateur est hautement efficace pour réduire les matières particulaires, épurer les gaz d'échappement du dioxyde de soufre et du dioxyde d'azote, et réduire leur signature thermique ainsi que leur manifestation visuelle.

Title: High frequency network multiplexed communications over various lines using multiple modulated carrier frequencies
Inventor: ABRAHAM CHARLES
IPC: H04B3/54
Filed: 2003-01-31
Granted: 2011-04-05
Abstract: An apparatus is provided for high frequency multiplexed electrical line communication for cable TV, telephone, internet, security and other control applications over the mid and low voltage power lines and directly through the transformers. The apparatus includes a transmitter, a receiver, a modem (14), a multiplexer and multiple couplers (28) at each of two or more locations along an electrical line (18). The couplers have capacitive circuits serially connected with an air-core or dielectric-core transformer (22). The capacitive circuits resonate with the transformer (22) at a preselected frequency. The coupler (28) eliminates noise and is matched to the characteristic impedance of the line at the preselected frequency, which linearizes communication on the line and allows high speed data and voice communication over long distances. Multiple modulators and demodulators are used to produce multiple modulated carrier frequencies.

Abstract: According to an embodiment of the invention, a repaired component is disclosed. The repaired component comprises an engine run component having a base metal substrate, a portion of the base metal substrate between about 1-3 mils in thickness and an overlying bond coat having been removed to create a remaining base metal substrate of reduced thickness. The repaired component further comprises a lower growth environmental bond coating comprising an alloy having an aluminum content of about 10-60 atomic percent applied to the remaining base metal substrate so that upon subsequent repair of the component, less than about 1-3 mils in thickness of the remaining base metal substrate is removed because of less environmental coating growth into the substrate than the prior bond coat. Advantageously, the repaired component has extended component life and increased repairability.

Abstract: Terrain anticollision equipment generally uses a display device presenting a two-dimensional synthetic map of the terrain flown over by the aircraft wherein the relief is shown in superimposed layers (S1, S2, S3 ) to which are assigned false colours representing the degree of the risk of collisions. The attribution of the false colours and/or the positions of the layers are referenced relative to a display reference altitude (RefAlt) related to the aircraft instantaneous altitude (a/c alt(t)) or to an altitude forecast in the short term for the aircraft (forecast a/c alt(t)), each of the referencing elements having its own advantages depending on the current situation for the aircraft. The invention provides for varying, through soft transitions, without visible surges on the screen, the reference altitude display based on the aircraft situation deduced from the flight parameters to obtain, at all times for the crew, the most meaningful and the most useful possible map taking into account the instantaneous situation relative to the collision risks.
