Patent number: 5050822Abstract: An arrangement for suppressing aerodynamic noise generated by cavity effect interaction between a wing flap shroud and one or more partially deployed trailing edge flaps. Noise suppression vanes are so positioned with respect to the shroud lower trailing edge and the leading edge of the wing flaps at partial deployment that eddies and vortices resulting from airflow separation at the shroud lower surface are diverted sufficiently by the noise suppression vanes to avoid significant noise inducing impingement of the separated flow on the flap leading edge.Type: GrantFiled: December 21, 1989Date of Patent: September 24, 1991Assignee: British Aerospace Public Limited CompanyInventors: Ian R.

Patent number: 5024401Abstract: An apparatus for controlling quad-line stunt kites of a type having a pair of handles with lines connected to each end of each handle. This is essentially all the control that is used during the normal kite flying procedure, but when it is desired to bring the kite line in or to let the line out, pick-up and/or pay-out structures are used in conjunction with the control handles. Specifically this pick-up and pay-out structure includes a first rod which extends through a pair of openings in the top of each of the control handles respectively and has a crank portion on one end thereof. A second rod extends through a pair of aligned openings in the lower portion of each of the control handles respectively. An axle, which is adapted to be rotated about an axis, is attached to one end of the first and the second rod and a tubular member is adapted to slide over the axle so that a person can grasp the tubular member in one hand and the crank in the other hand to rotate both rods and both handles about the axis.Type: GrantFiled: June 8, 1990Date of Patent: June 18, 1991Inventor: Hiroshi Nakashima

Patent number: 5011339Abstract: The invention relates to a process for dispensing indentical pieces having a symmetry of revolution about an axis, such as rivets; this process comprises arranging the pieces one after another in a tube (2) which has a hollow center (2a) adapted to assure the guiding thereof, admitting a compressed fluid into the tube behind the last piece (1D), and distributing said fluid along the length of the tube toward the hollow center (2a) thereof, to the interior of one or several longitudinal passageways (2b), such that the fluid pressure is exerted along the hollow cetner in the spaces (E) separating the pieces, up to the first piece (1P) on which the pressure acts for assuring its transfer. The process of the invention permits dispensing a very great number of pieces without risk of jamming in the tube and with a precise guiding permitting maintaining the alignment of the axes of the pieces.Type: GrantFiled: December 7, 1989Date of Patent: April 30, 1991Assignee: Ste.

Patent number: 5000400Abstract: The disclosed invention provides a main landing gear (12, 14, 16, 18) for a high speed (supersonic) aircraft (10) which may be wing-stowed and -mounted in a relatively thin wing (22, 24). The main landing gear (12, 14, 16, 18) is characterized by an inboard gear (12, 14) including a post (58) having a transverse trunnion (52) at a first end (56 or 54) operably mounted on the wing (22, 24). The trunnion (52) is journalled for rotation about an axis for movement of the post (58) between operative and stowed positions. This axis is substantially transverse to the body of the aircraft for forward rotation of the inboard gear (12, 14). A wheel assembly (78, 80) is operably attached at a second end of the post (58). The wheel assembly (78, 80) has a plane of rotation which when stowed in the wing (22, 24) is substantially vertical. In combination with the inboard gear (12, 14) is an outboard gear (16, 18) which includes a post (90) having a skewed trunnion (92) at a first end operably mounted on the wing (22, 24).Type: GrantFiled: December 15, 1989Date of Patent: March 19, 1991Assignee: The Boeing CompanyInventor: V.

Patent number: 4991798Abstract: In order to fill the cryogenic engines of a launcher with propellents up to the time of launcher lift-off, an apparatus is proposed which has a tube section (20) connecting pipes on the ground and on board the launcher (12). A weakened zone (22) of said tube section is automatically broken during lift-off by a mechanism (24,38) applying a tensile stress to the section. This mechanism comprises several assemblies of links (26,28) bearing on the tube section on either side of the weakened zone and a bearing surface (38a,38b) formed in a sleeve (38) fixed with respect to the ground and with which is in contact a protuberance (26a) formed on one of the links of each assembly (26,28).Type: GrantFiled: November 13, 1989Date of Patent: February 12, 1991Assignee: Aerospatiale Societe Nationale IndustrielleInventor: Jacques Landat

Patent number: 4975000Abstract: An end tube assembly for the outlet gate of a railroad hopper car includes an end tube and an end tube cap for closing the end tube. The cap is pivotally connected to the end tube and there is a diametrically opposed latch between the cap and end tube. The cap has a guide which extends toward and over the end tube and there is a ramp on the end tube in alignment with the guide to coaxially direct the guide and cap on the end tube during closure. There is a lock on the end tube adjacent the ramp to prevent relative circumferential movement between the cap and end tube. The end tube mounts a gasket which faces the end tube cap. The cap has a rim extending outwardly therefrom for contact with the gasket. The extension of the rim gradually varies from at least one area of greatest extent to at least one area of lesser extent to compensate for distortion of the cap when it is latched onto the end tube.Type: GrantFiled: November 22, 1989Date of Patent: December 4, 1990Assignee: Gen-Tech, Inc.Inventors: William E.
