  • Publication number: 20050273385
    Abstract: An electronic advertising contract grants fuel credits in exchange for placement of advertising on private and/or commercial vehicles. The contract is implemented using a vehicle equipped with an advertisement detection mechanism. The advertisement detection mechanism detects at least one of presence of an advertisement positioned for vehicle display and absence of an advertisement positioned for vehicle display. A processing mechanism, coupled to the advertisement detection mechanism, a clocking mechanism, and memory, generates an electronic advertisement display log in memory setting forth at least one of a time interval for which a display of the advertisement is detected, a time interval for which a display of the advertisement is not detected, a mileage interval for which a display of the advertisement is detected, and a mileage interval for which a display of the advertisement is not detected. The electronic advertisement display log is updated periodically or at predetermined intervals.

  • Patent number: 4812321
    Abstract: Disclosed is a pneumatically powered automatic apparatus and method for subdividing one or more loaves of dough supported in a partitioned single use, nonmetallic tray at a processing station intermediate the opposite ends of a conveyor. A tray of dough is introduced into the apparatus as a tray of subdivided dough exits onto the conveyor. The dough subdivider functions to draw the skin of the roll of dough from the upper and lower sides thereof permanently into closely spaced relation between adjacent subdivisions of dough thereby leaving the subdivisions connected solely by a web which is readily frangible when the dough is baked. The dough subdivider operates dry and free of lubricant. Trays of dough exiting from the apparatus are maintained frozen and wrapped until ready for the oven at either a local or a distant comsumption site.
