 Appl.No PCT/FR1998/000310 Applicant HISPANO-SUIZA AEROSTRUCTURES Inventor BAUDU, Pierre, André, Marcel
The invention concerns a bypass turbojet thrust reverse system comprising pivoting doors (7a, 7b) integrated in direct jet in the outer wall of the fan air duct (15) and constituting flux deviating obstacles providing thrust reversal. At least two actuators (23) controlling the door (7a, 7b) movements are associated with a synchronising device (19) consisting of an electric motor (20) and its electronic power system (21) and a bezel box (22) connected by a transmission linkage (26) to each actuator (23) respectively. Thus the security of operation is ensured in the event that the door is not locked.

Said door (20) pivots about a shaft (21) located downstream therefrom, the upstream edge projects into the duct and the door (20) remains within the space occupied by the pod. The door (20) comprises an internal nozzle space (37) between a first upstream opening (36), an inner panel (27), an outer panel (29) and a second opening (32) provided on the downstream side between a downstream edge and said outer panel (29). In the thrust reversal position, at least part of the deflected flow passes through said internal space (37) of the scoop-like door (20), whereas in the direct thrust position, the second opening (32) is covered by a covering member (33) integral with the fixed structure, and the forces exerted by the flow on the inner panel (27) maintain the door (20) in the closed position.

A bypass jet engine thrust reverser comprising pivoting doors (7) integrated into the outer pod wall in the direct thrust position and pivoted out by a hydraulic cylinder (8) to form deflecting buckets for thrust reversal. An internal upstream panel (20) lines the inner surface of each door (7), and the door (7) and the upstream panel (20) are pivotable about separate respective pivots (27, 28). The door (7) and the upstream panel (20) are joined together via a so-called three-point linkage (30) hinged to a first point (31) on a support (32) secured to the upstream panel (20), to a second point (33) on the door (7), and to a third point (34) at the end of the rod of the control cylinder (8), whereby no opening torque is transmitted to the door (7) in the direct thrust position by the pressure forces exerted on the upstream panel (20).

An improved process for stripping gold cyanide from activated carbon is disclosed. The process involves contact of gold-laden activated carbon with a strong base at ambient temperatures followed by elution with an aqueous solution containing an organic solvent, preferably aqueous acetonitrile or methanol. Gold cyanide is separated from the aqueous/organic solution by ion-exchange technology, preferably using a weak base ion-exchange resin, followed by elution with a strong base.

A bypass jet engine thrust reverser comprising pivoting doors (7) integrated into the outer pod wall in the direct thrust position and forming deflecting buckets for thrust reversal. An internal upstream panel (20) lines the inner surface of each door (7) and is hinged to the same pivot (27) as the door (7). The linkage between the door (7) and the upstream panel (20) consists of an epicyclic gear train assembly comprising a planet gear (31) secured to the door (7), an outer sprocket wheel (34) secured to the upstream panel (20), and at least one freely rotatable planet pinion (33) secured to the fixed structure of the reverser. When a control means switches to the thrust reversal position, the door (7) and the upstream panel (20) pivotally rotate in opposite directions.
