A portable advertising platform system for store front, street side and indoor promotions. The platform can elevate signs and products above obstacles. Items are fastened at their tops only allowing them to freely swing; wind resistant. This rugged, lightweight platform is made from plastic or aluminum and consists of several joints interconnected by square shaped insert tubes; thumb screw fastening. Tubes can couple together to form longer members. Joints can rotate 90 degrees to create perpendicular branches. The platform consists of a lower cart with several vertical mounts, supporting an upper web with multiple tiers and overhanging arms. The platform can substantially stretch horizontally, vertically and in width providing numerous configurations. The 4 leg levelers telescope multiple feet both horizontally and vertically to level the cart on rough uneven terrain. Leg levelers also act as durable brakes; friction with ground. Detachable large 8 inch wheels swivel for easy maneuvering.

The present invention relates generally to illuminated display devices and methods of displaying indicia, advertisements, etc. on a changeable illuminated display. The display device comprises a frame structure, a plurality of openings formed in the frame structure, the plurality of openings comprising first and second open spaces disposed at top and bottom positions, respectively, of the frame structure, and the plurality of openings further comprising a third open space disposed between the first and second open spaces. The display device further comprises a compact image display device operable to display an image, the compact image display device held and positioned relative to the frame structure such that first, second, and third different portions of the image, when displayed by the compact image display device, are visible through the plurality of openings first, second, and third open spaces, respectively. Additionally, control circuitry is coupled to the compact image display device.

A roll display sign device for displaying an information sheet for a vehicle includes a housing, which defines an interior space. The housing is selectively engageable to a window of a vehicle so that the housing is removably engaged to the window. A slot is positioned in the housing. A panel, which is wound and which is positioned in the interior space, is reversibly extensible through the slot so that the panel is viewable through the window of the vehicle. The panel has indicia positioned thereon, can selectively engage indicia, or can selectively engage a sheet upon which indicia are positioned. The indicia are capable of being read by a person who is positioned proximate to the window.

The window-hanging vehicle-locating device is configured for use with a vehicle. The window-hanging vehicle-locating device is removably attached to a window of the vehicle. The window-hanging vehicle-locating device is an optical signaling device that is attached to the vehicle for the purpose of visually locating the position of the vehicle. The window-hanging vehicle-locating device is remotely controlled in a manner that allows for the identification of a specific vehicle within parking lot. The window-hanging vehicle-locating device comprises a clip, a telescopic pole, a flag, a lamp, a remote interface circuit, and a user control. The flag and the lamp attach to the telescopic pole. The telescopic pole and the remote interface circuit attach to the clip. The clip attaches the window-hanging vehicle-locating device to the superior edge of the window. The user control remotely controls the operation of the window-hanging vehicle-locating device.

A flexible decorative display device for attachment to a hitch receiver. The flexible display device is formed from a bendable sheet having a distal front surface, a proximal rear surface, an outer shaped outline, and interior shaped edges. The interior shaped edges form both a central opening to accommodate the trailer hitch receiver and a tongue. The tongue has tongue alignment cavity edges that define an interior tongue pin-receiving cavity. The tongue bends backwardly at a flexure line to fold back over the outside of the receiver tube, aligning the tongue pin-receiving cavity with the pin-receiving hole of the receiver.

A LED sign which can be programmed to display a desired message can be made utilizing a sign kit comprising (1) one or more faces, wherein each face is comprised of a plurality light emitting diodes; (2) a receiver having erasable, programmable read-only memory and a USB printer port plug; (3) a power supply; and (4) a USB flash drive which is adapted to connecting to the receiver through the USB printer port plug; wherein the USB flash drive is programmed to reset the erasable, programmable read-only memory of the receiver by erasing any preexisting data which may reside in the read-only memory of the receiver and to program the erasable, programmable read-only memory with auto executing script to set the desired message to be displayed. The LED sign can be mounted on a trailer for display as the sign is moving or for display in a stationary location.

An electronic apparatus includes a display module 3, a frame-like housing member 2, a temporary holding member 6, and a fixing member 4. The frame-like housing member 2 has side wall sections 2a-1 and 2a-2 opposing each other. The temporary holding member 6 is assembled to the frame-like housing member 2 by being engaged and aligned with the side wall section 2a-2 and by being engaged with and fixed to the side wall section 2a-1. The fixing member 4 is assembled to the frame-like housing member 2 by being engaged and aligned with the side wall section 2a-1 and by being engaged with and fixed to the side wall section 2a-2.

The invention relates to the production of (meth)acrylic acid, and to implementation of a step of condensing water contained in a recycled gas effluent and/or in the air feed in a (meth)acrylic acid production process, which further includes a process for purifying a reaction mixture comprising (meth)acrylic acid without using azeotropic solvent and based on the use of two distillation columns.

A license plate holder has a perimeter capable of holding a number plate. The perimeter has a upper rim, a right rim, a left rim and a lower rim forming an opening through which a license place may be visible. The license plate has both at least one camera lens and at least one proximity sensor attached to it.

A vehicle mounted sign assembly comprises a base member having a top surface, a bottom surface, a leading edge, a trailing edge and side surfaces between the leading edges and the trailing edge, with the side surfaces tapering rearwardly to the trailing edge. The assembly further comprises a mounting assembly configured to support the base member. The mounting assembly comprises a first and a second vertical bars extending through respective openings on the bottom surface of the base member, a first and a second horizontal bars mounted in parallel and positioned between the first and second vertical bars, and a first and a second suction cups attached to respective bottom end of the first and second vertical bars for attachment to the body or a window of a vehicle.
