Abstract: A modular backlight display board employs an extrusion that receives multiple LED modules that may be assembled together with end connectors. By trimming the extrusion to different lengths and installing different numbers of LED modules within the extrusion, a wide variety of different widths of backlight can be readily created.

Abstract: A canopy assembly for sheltering a drive-up ordering station of a fast food restaurant can pivot out of the way when impacted by a vehicle and return automatically to a centered position. A centering feature mounted to a column supporting a roof structure engages a pivotal coupler to bias the roof to a center position. This feature includes a pivot post assembly extending across the cavity and through a pair of helical slots in the coupler. When a leading end of the roof assembly is struck by a vehicle, the coupler is rotated and the pivot post engages the slots so that the coupler translates upward. The coupler is biased by gravity to a centered position in which the top ends of the slots rest on the pivot post.

Abstract: A sign assembly can be formed by attaching several modules together. Each module includes a lamp assembly for back lighting the sign display, and has walls with a plurality of dovetail grooves in their exterior surfaces. Double dovetail unions engage the dovetail grooves in abutting walls of a pair of modules to fasten those modules together. Other dovetail unions fill in exposed grooves or fasten a frame around the perimeter of the sign assembly. Each module has a wiring assembly with connectors at each corner so that adjoining modules can be electrically interconnected. This enables electricity to be externally applied to only one module of the assembly with the other modules receiving electricity directly or indirectly from that one module.

Abstract: A jet engine for an aircraft has a thrust reverser including one or more doors which define at least a part of the throat of the engine's nozzle. The engine further includes a latch mechanism for retaining the doors in a stowed position. The doors may be deployed for reversal of engine thrust, but are also capable while stowed of being pivoted in a limited way to change the cross-section area of the throat of the nozzle.

Abstract: An improved S-duct for turbo-jet engined aircraft. The present invention allows a high volume of high energy air to traverse the S-duct at a high pressure recovery ratio.

Abstract: To eliminate the fish-mouth geometry at the downstream portion of a thrust reverser fitted jet engine which results from the formation of substantially arcuate notches when the thrust reverser doors are stowed, moveable flaps are positioned in close proximity to the doors such that when the doors are in their stowed position, the flaps would fill, at least partially, the arcuate notches to effect a substantially planar exit opening, thereby substantially eliminating the fish-mouth geometry. Moreover, the flaps can be used to effect a uniform thickness for the exit opening of the jet engine by each having a shape corresponding to that of the corresponding arcuate notch; and the principal outer surfaces and inner surfaces of the flaps provide continuity with the outer surfaces and the inner surfaces, respectively, of the doors, with the ends of the flaps have trailing edge which have thicknesses similar to those of the trailing edges of the doors.

Abstract: A daylight cassette adapter for a photographic processor which may be mounted directly on the processor. The cassette provides an enclosure into which photographic cassettes may be loaded whereby cassettes of various size may be developed in daylight by the processor. The adapter also includes a hinged lid, the sides of which form light seals with the walls of the adapter housing. The adapter is particularly useful with processors which are adapted to handle only a particular size or type of cassette and adapts the processor to use various sizes and types of cassettes.

Abstract: Modifications to a jet aircraft of the type having aft fuselage-mounted engine nacelles overlapping trailing edge portions of the aircraft's wings, wherein a channel area defined by the fuselage, wing, pylon and attached nacelle is shaped to prevent air flowing therethrough from forming a shock wave during flight operation in the transonic regime, resulting in significant drag reduction as compared to an unmodified jet aircraft of a similar type. Further modifications to the jet aircraft's wings provide additional lift while significantly reducing drag as compared to a similar, unmodified aircraft. The present invention is particularly adaptable for use with Gates Learjet type aircraft, especially Models 23, 24, 25 and other models having similar nacelle, pylon and inboard wing arrangements.
