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 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.
