Title: Thermal anti-icing system
Inventor: GREGORY KARL
IPC: B64D15/04
Filed: 2008-03-05
Abstract: An air intake duct of an aircraft engine or other component is provided with a thermal anti-icing system. The front of the air intake duct comprises a toroidal outer skin (16) which forms, with a toroidal, internal bulkhead (18), a toroidal plenum (8) about the centre line (26). The bulkhead has an inner edge nearest the centre line. Within the plenum there is a toroidal inner skin (9) defining with the outer skin a substantially continuous toroidal channel (19). Hot air is supplied via an inlet (7) to the plenum (8). The air flows into an inlet (14) at an end of channel (19) and out of an outlet (11) through the bulkhead (18). This provide more heat to the leading edge of the duct, and to the surface of the duct facing the centre line, than to other parts of the duct to prevent build up of ice which may enter, and damage, the engine. This reduces the mass flow of hot air needed for de-icing.

Abstract: Contemplated plant configurations and methods employ a vaporized and supercritical LNG stream at an intermediate temperature that is expanded, wherein refrigeration content of the expanded LNG is used to chill one or more recompressor feed streams and to condense a demethanizer reflux. One portion of the so warmed and expanded LNG is condensed and fed to the demethanizer as reflux, while the other portion is expanded and fed to the demethanizer as feed stream. Most preferably, the demethanizer overhead is combined with a portion of the vaporized and supercritical LNG stream to form a pipeline product.

Abstract: A downhole rotary diverter assembly includes multiple passages for selectively aligning with multiple boreholes. The diverter assembly can be selectively actuated to direct a tool or tubing through-passage toward a desired borehole. The primary tool through-passage of the diverter assembly can be alternately and continually aligned and re-aligned with a desired borehole out of multiple boreholes, while the diverter assembly remains in the well.  After a single trip into the well, and placement of the diverter assembly in a well junction, the diverter assembly can be actuated to rotate flow passages into alignment with multiple boreholes. An actuation tool may be lowered into the diverter assembly and manipulated to activate a mandrel. The mandrel is guided by an indexing mechanism to rotatably cycle through discrete and predetermined alignment positions that correspond generally with the stop positions of a guide pin in a guide slot of the indexing mechanism.
