20100089210 | APPARATUS AND METHOD FOR CONVERTING INSULATED PANELS - A method for producing a duct from a planar board having two opposed substantially parallel edges with metal foil facings on opposed major surfaces of the board is disclosed. The method comprises making planar cuts through one of the metal foil facings and at least most of the planar board there below to produce a blank with 3 parallel āV shaped grooves which are parallel to angled edges of the blank. A duct is formed by folding the blank so that the āVā shaped grooves form three of the edges of the duct, and the angled edges form the fourth of the edges. | 04-15-2010 |
20140261846 | Clad duct - A clad duct comprising an outer sheet of thermoplastic material and an inner duct of rigid foam is disclosed. The outer sheet of thermoplastic material is bonded to the inner duct. The outer sheet has a first edge and a second edge and a seal is provided to seal the first edge and the second edge. | 09-18-2014 |
20140271972 | HEAT BRAKE - A heat brake for heating and softening a thermoplastic sheet for bending is disclosed. The heat brake has a split work piece support table having two edges defining a slot between adjacent portions of the table. A first plenum is provided below the split work support table. During operation, the first plenum has a negative pressure. Air is drawn into the first plenum through the slot when a work piece does not span the slot. When a work piece spans the slot, the flow of air into the first plenum is reduced. The heat brake has a tube heater with an outlet nozzle positioned in the first plenum. A portion of the tube heater is positioned in a second plenum which is pressurized during heating. Air is moved from the second plenum through the heater tube and is directed against a work piece supported on the table. | 09-18-2014 |
20140290836 | METHOD FOR PRODUCING A CLAD DUCT - A method for producing clad duct from a laminate is disclosed. The laminate is a sheet of thermoplastic material bonded to an insulative foam board. V-shaped grooves are formed in the foam board, opposite the sheet. The sheet is heated in the vicinity of one of the grooves, until pliable. The sheet is then bent, where it has become pliable, to close the groove. The heated and bent sheet is then cooled until it is no longer pliable and retains its bent shape. The heating, bending, and cooling steps are repeated for the other grooves until edges of the laminate are brought together. The edges are then sealed. | 10-02-2014 |

20090092753 | METHOD OF ALUMINIZATION IN THE VAPOR PHASE ON HOLLOW METAL PARTS OF A TURBOMACHINE - A method of aluminization by deposit in the vapor phase for protection against oxidation at high temperature of a metal part of a turbomachine. The part includes a cavity with an opening that can be accessed from the outside. A halide is formed by reaction between a halogen and a metal donor containing aluminum, then the halide is transported by a carrier gas to come into contact with the metal part, the metal donor being placed at least partly in the cavity. The metal donor is in the form of a pellet obtained by hot sintering under pressure of a mixture of metal powder. | 04-09-2009 |
20090092826 | PROCESS FOR THE VAPOR PHASE ALUMINIZATION OF A TURBOMACHINE METAL PART AND DONOR LINER AND TURBOMACHINE VANE COMPRISING SUCH A LINER - An aluminization process by vapor phase deposition for high-temperature oxidation protection of a metal turbomachine part. The part including a cavity into which a metal component is introduced and assembled from an opening in the part. A halide is formed by reaction between a halogen and a metal donor containing aluminum, then the halide is transported by a carrier gas in order to come into contact with the metal part, wherein the metal component has first, before the implementation of the process, been surface-enriched with aluminum in order to serve as an aluminum donor. | 04-09-2009 |
20090123288 | METAL IMPELLER BLADE MANUFACTURED BY MOLDING AND METHOD OF MANUFACTURING THE IMPELLER BLADE - The present invention relates to an impeller blade for turbomachine formed by molding, comprising a blade, at one end of which is provided a heel formed of a single piece with the blade, to which it is joined at the level of a connection area, the heel comprising a platform on which is provided at least one sealing plate, a first bath being provided in the platform, characterized in that a second bath is provided in the first bath, at the level of the connection area between the blade and the heel. | 05-14-2009 |
20120224975 | PROCESS FOR THE VAPOR PHASE ALUMINIZATION OF A TURBOMACHINE METAL PART AND DONOR LINER AND TURBOMACHINE VANE COMPRISING SUCH A LINER - An aluminization process by vapor phase deposition for high-temperature oxidation protection of a metal turbomachine part. The part including a cavity into which a metal component is introduced and assembled from an opening in the part. A halide is formed by reaction between a halogen and a metal donor containing aluminum, then the halide is transported by a carrier gas in order to come into contact with the metal part, wherein the metal component has first, before the implementation of the process, been surface-enriched with aluminum in order to serve as an aluminum donor. | 09-06-2012 |
