Abstract: The speedbrake of the present invention is comprised of a housing which can be stored in a faired surface of an aircraft which is not within the aerodynamic envelope of its wing. The housing is associated with a track system which permits it to be translated between a retracted position, where it is located inside of the faired surface, and an extended position, where it protrudes into the airstream to create drag when the aircraft is in flight. Pivotally mounted in the housing are plates which rotate up into the housing when the speedbrake is retracted and extend downwardly from the housing when the speedbrake is extended. The speedbrake is installed in pairs with one being located on each side of the aircraft. One of the speedbrakes is moved between its extended and retracted positions by a motor and the other speedbrake is connected to the motor-powered one by cables.

Abstract: A motor includes a pair of linear actuators having a rack connected to their actuation elements. The linear actuators are powered in a manner which causes them to oscillate. A pair of sector gears which mesh with the rack are rotatably mounted on individual shafts to rotate clockwise when the rack moves in one direction and counterclockwise when the rack moves in the opposite direction. One of the sector gears is coupled to its associated shaft through a counterclockwise one-way clutch and the other sector gear is coupled to its shaft through a clockwise one-way clutch. The shafts have intermeshing drive gears mounted on them and thereby rotate counter to one another. An output gear can be coupled to either drive gear through an idler gear which is engaged with the appropriate drive gear by a solenoid-operated carriage. When the rack is moving in a first direction one of the sector gears is coupled to its shaft through its one-way clutch to rotate the drive gears.

Abstract: A machine for making wood moldings includes an endless feed belt extending downstream from the upper face cutter head for holding short lengths of wood pieces securely between the working stretch of the feed belt and the underlying bed plate and delivering it through side and lower face cutter heads. An air plenum container overlies and bears against the working stretch of the feed belt to provide uniform feed pressure to the wood throughout the length of the working stretch and delivers air under pressure through a multiplicity of holes in the plenum container to the confronting side of the working stretch of the belt for minimizing friction between the belt and container. Short lengths of wood pieces are delivered in spaced-apart relationship to the upper face cutter head between an elongated side feed belt and an elongated air fence.
