Abstract: An amphibious airplane having an engine assembly mounted at a top center location in the fuselage, and a tail assembly having a horizontal fin in an elevated position so as to be in the propeller air stream. A lift augmenting aerodynamic surface is positioned at the top middle portion of the aircraft fuselage, with the propeller being at the concavely curved rear end of the lift augmenting surface. A pair of platforms are positioned on opposite sides of the fuselage at lower locations adjacent to a passenger section of the aircraft. These platforms are aerodynamically aligned and also have strakes extending forwardly therefrom along opposite sides of the fuselage. In cruise mode, the increased velocity imparted to the propeller air stream acts on the horizontal fin to exert a downward force, with the various forces of the airplane balancing each other.

Abstract: A retaining wall system and method for stabilizing earthen walls comprises box members assembled together to form a reinforcing wall assembly and anchor mesh connected to the box members and buried within the earthen wall. The box members define an interior cavity and a rear wall that engages the face of the earthen wall. Waste material such as used tires or waste dirt may be placed within the interior chambers of the box members. The anchor mesh is attached to the rear wall to inhibit lateral movement of the reinforcing wall assembly. The box members are connected to the anchor mesh by locking pins that extend through loop portions of the anchor mesh and engage a front face of the wall panels. Anchor bars are connected to the loop portions of the anchor mesh. These anchor bars engage a back face of the box members to control and limit the movement of the box members relative to the anchor mesh as earth is back-filled against the box members.

Abstract: An scraper system for removing acoustic texture materials comprising an integral debris collection assembly. The system comprises a scraper assembly comprising a scraper blade maintained at an angle with respect to a handle portion. A band is provided that defines at least a portion of a rectangular perimeter that, in use, is arranged below the scraper blade. A bag is attached to the band so that acoustic texture material removed by the scraper blade falls into the bag. The band is made of resilient material and is attached to the scraper assembly in a manner that allows the band to deflect when it contacts a wall surface adjacent to the ceiling surface. This allows the scraper blade to reach allow the way to wall surface. But the band returns to its original position with the perimeter defined thereby under the blade when the blade is not scraping near the wall surface.

Abstract: An adjustable mobile base that accommodates machines of different effective footprints and allows them to be selectively moved from place-to-place or fixed at a given location. The mobile base assembly comprises a frame assembly comprised of corner members and side members. The side members are telescopically received within the corner members such that a width dimension and depth dimension of the base assembly can be changed to accommodate machines having different effective footprints. A lock system may be provided which employs one or more lock assemblies. Each lock assembly comprises a lock member that is slidably received within a lock housing and a drive member which is threadably received within the lock housing. Rotating the drive member in one direction elevates one or more wheels of the base assembly and thus frictionally engages the floor surface and prevents movement of the machine on the base assembly.

Abstract: Pulse propagation analysis to ascertain whether and anomaly such as surface corrosion exists on a section of conductive member such as pipe. Anomalies such as surface corrosion result in localized velocity changes of pulses propagating along a conductive member. These localized velocity changes exhibit themselves in changes in waveform, rise and fall time, amplitude, and time delay of a pulse with respect to a fixed time reference. To allow such anomalies to be located, two pulses are generated such that they intersect at intersecting locations along the conductive member. The resulting modified pulses are analyzed for perturbations indicative of localized velocity changes.
