An exhaust flap for use in the exhaust section of an aircraft gas turbine engine is built with increased service life and ease of replacement. The exhaust flap includes convergent nozzle flaps, divergent nozzle flaps, convergent seal flaps and divergent seal flaps. The exhaust flap comprises a frame assembly with means for mounting in the engine and effecting its movement. The frame assembly is particularly characterized in having an open frame with at least one rail having a receiving channel. ...

Improved flaps for tires have a reinforcement in the region of the increased thickness of material around the valve hole and the reinforcement comprises a rigid tubular insert within the valve hole and a layer of reinforced elastomer which forms a covering of the radially inner surface of the flap all around the insert.

A flap and linkage system for a STOL (short takeoff and landing) aircraft having swept tapered wings. The flap linkage fairings are streamlined and the flaps move basically aft in the airstream direction and rotate in a hinge system which is approximately parallel to the rear wing spar. The length of movement of the flap is proportional to the length of the wing chord at the point of measurement, approximating a conic motion of the flap support points. Hydraulic actuation of the flap linkage als...

A double four-bar linkage for flap actuation on a STOL (Short Take Off and Landing) aircraft with interconnecting linkage to proportionally deflect the spoiler as the flaps are extended.

A mud flap device which is particularly adapted for use with truck trailers, the device consisting of a longitudinally reinforced guard member which includes securing means across the top edge thereof and, further, which is formed with a forwardly protruding portion for alignment generally with a vehicle tire such that the protruding portion of the guard member will maintain the lower portion of the guard member displaced by a predetermined amount from the tire.

Mud flap devices which are particularly adapted for use with truck trailers that are adjusted in what is known as the west coast setting of the rear or tandem wheels, that case where the wheels are set to the extreme rear of the trailer, such mud flap devices being characterized by a forward protruding transverse configuration which in the mounted position will be disposed adjacent the rear edge of the trailer wheel and which will suspend a lower flap portion downward at a position several inche...

A shaped sanitary napkin. The sanitary napkin of this invention has an absorbent means, such as an absorbent core, and two flaps extending outwardly from the absorbent means. Each flap is associated with the absorbent means along a nonlinear line of juncture and each has two axes of flexibility. In use, the absorbent means is secured in the crotch of a panty and the flaps are secured about the elastic edges of the panty so that, when the panty is worn, the absorbent means is held adjacent the bo...

A disposable absorbent article for personal wear has an inner layer, an outer layer and an absorbent body disposed therebetween. Containment flaps are secured to the inner layer of the article, with each flap having a first layer extending outward from the inner layer of the article to a distal end of the flap. A generally liquid permeable second layer of the flap extends in opposed relation with a medial surface of the flap first layer of the flap and is free from fixed engagement therewith alo...

An apparatus is provided to reinforce an airbag while it is deploying through an airbag cover. An undeployed airbag is wrapped in a cover deployment flap that may be a thin piece of material. The cover deployment flap is located between the airbag and the airbag cover. As the airbag deploys, the cover deployment flap remains between the airbag and the airbag cover until the airbag cover is sufficiently open. The cover deployment flap may have multiple folded configurations to wrap the undeployed...
