20140103015 | INSTALLATION FOR FABRICATING A PART BY SELECTIVELY MELTING POWDER - An installation for fabricating a part by selectively melting powder, the installation including a mechanism producing a beam, for example a laser beam or an electron beam, and a mechanism moving a point of impact of the beam over a layer of powder. The installation further includes a collector element for collecting projections of molten powder produced during local melting of the powder by the beam, the collector element including an opening for passing the beam, and a mechanism configured to move the collector element jointly with the beam over the layer of powder. | 04-17-2014 |
20140217068 | METHOD FOR WELDING AND FOR HARD SURFACE DEPOSITION OF METAL PARTS MADE OF ALUMINIUM BY A MIG METHOD WITH PULSED CURRENT AND FILLER WIRE - A method for hard surface deposition on aluminium metal parts of a turbine engine using MIG welding equipment which includes a pulsed current generator and pulsed filler metal wire feed, wherein the deposition is achieved using a filler metal wire whose composition is of the same nature as the composition of the aluminium alloy of the part to undergo hard surface deposition, with the pulsed metal wire feed and speed of deposition on the metal part of the turbine engine being adapted to carry out deposition without hot fissuring. | 08-07-2014 |

20140158824 | RETRACTABLE EQUIPMENT SYSTEM INCLUDING A DEVICE OPTIMIZED FOR DRIVING PROTECTION FLAPS - A system for retractable equipment is proposed that has movable protection flaps and in which a flap drive device serves to drive the flaps in optimized movement, while providing mechanical coupling between the flaps and the retractable equipment in such a manner that a common motor member can be used for driving both the equipment and the flaps. The drive device includes a cam secured to a frame of the system and a cam follower mechanically coupled to the retractable equipment and to a flap drive member. The path followed by the retractable equipment can thus also be optimized. | 06-12-2014 |

20100096108 | Evaporator coil bypass device for HVAC System - A bypass device to seasonally bypass an evaporator coil in a building's HVAC system to improve efficiency and reduce dust accumulation. The bypass device comprises one or more bypass diverters around an evaporator coil in an HVAC system, wherein bypass doors may be manipulated so as to close the air path through the evaporator coil and force air to flow through bypass diverters instead. The bypass doors are adjustable using control arms and may be maintained in either a flow-through or bypass position, so as to permit the air flow to travel through the evaporator coil, or bypass the coil, as the operator chooses. The control arms may alternatively be manipulated by a motor and connected to the thermostat so as to automatically select the appropriate position depending on the settings of the thermostat. | 04-22-2010 |
