Abstract: A thrust reverser includes a pair of doors covering corresponding portals in an exhaust duct between an inlet and outlet nozzle at opposite ends thereof. The duct also includes a pair of side beams having actuators mounted thereon, and operatively joined to the doors for selective rotation thereof about corresponding pivots. Blister fairings are disposed inside the duct and sealingly join the doors to the beams around respective ones of the pivots.

Abstract: A dome shaped structure, and the method of constructing it, are described using curved gore-shaped construction panels which have grooves in their side edges. Rectangular tubular joining members are placed in the grooves, secured therein, and serve to join adjacent panels together. This provides a level surface where the panels are joined so that such adjacent edges of joined panels are even making the interior surface suitable for use as a projection surface.

Abstract: An improved rim for use on a heavy, off-road vehicle formed of a tubular rim base member having a circumferential groove in the outer cylindrical surface adjacent one end thereof, the groove being of semi-circular cross-sectional configuration, a first bead flange secured at one end of the rim base member, a second bead flange slidably mounted on the other end of the rim base providing a contour substantially the same as the inner contour of the first bead flange, the second bead flange having a circumferential recess in the inside surface at the outer end thereof, and a split circular cross-sectioned locking ring removably received within the base member circumferential groove so that when the second bead flange is slidably positioned on the rim base, the locking ring can be placed in the groove and when the second flange slides outwardly the recess therein retains the locking ring within the groove and the locking ring serves to retain the second bead flange on the rim.

Abstract: This invention relates to a wheel supported heavy load carrying vehicle which comprises a frame upon which a load may be supported. The frame includes a structural cross-member. Unlike the prior art, the spherical bearing is made an integral part of the cross-member. An axle box assembly is used to support the wheels which support the bulk of the load. The box assembly has a nose cone which has a concave bearing which mates with the spherical bearing on the structural cross-member.
