US Classification:

705 16

Abstract:

A system for controlling outdoor price signs for fuel products includes a control center. The control center determines a price for a fuel product for a number of fuel stores. The control center receives a variety of data that may have an impact on fuel prices, including competitive data from a neighborhood store. The control center has a number pricing formulas and applies a selected formula to set a fuel price at one of the fuel stores. The price is sent to a store controller. The store controller passes the fuel price information to a point of sale device that updates a pump price and an outdoor controllable sign. The sign includes feedback that it not only received the correct price but that it correctly displays the price and the price is legible.

International Classification:

G09F 1118

US Classification:

40471

Abstract:

A scroll apparatus formed as a box-like framework with a front view area which houses a pair of rollers upon which a message web is wound in a scroll manner such that an exposed portion of the web extends between the rollers along the view area. A drive strap has each of its opposite ends fixed to a respective roller with its respective end portions each wrapped about itself in a circumferential direction opposite the direction that the message web is wound about the associated roller. The drive strap and web thus form a loop drive assembly for the rollers. Tensioning structure is provided for the drive assembly to keep the web taut and to remove slack due to variations in winding diameters. A color panel is positioned adjacent the message web on a side thereof opposite the view area, and the apparatus is internally lit so that the message web is illuminated by light passing through the color panel. Several apparatus, in modular form, may be used to construct a larger display sign.
