Abstract: A display tray with multiple side panels attached to one another to form tray sides. The display tray includes a tray surface having an area defined by the first, second, third, and fourth four side panels. Additionally, the display tray includes multiple corner columns, with a corner column located in each corner of the tray. Each corner column upwardly extends from the tray surface and is sturdy enough to support the stacking of another design tray on top.

Abstract: A knockdown configured for assembly into a display having first, second, third and fourth side panels and at least one shelf. The knockdown has a first flat wall including the first and third panels attached along a first fold line and lying in a first substantially same plane and a second flat wall including the second and fourth panels attached along a second fold line and in a second substantially same plane with first and second corners whereat the first and second walls are attached to one another. At least one shelf, having a front edge and a back edge, is integrally attached at the front edge thereof to the first side panel and extends in the first substantially same plane. A plunger panel between the first and the second side panels has a front surface thereof adhesively attached to the at least one shelf adjacent its back edge.

Abstract: A method and apparatus for making a reinforced product of bituminous material comprises drawing a reinforcing mat through a tank of molten bituminous material to impregnate the mat, pulling the impregnated mat through metering rolls to establish the final thickness of the reinforced product, and controlling the relative position of the mat within the reinforced product by controlling the angle of incidence of the impregnated mat with respect to the metering rolls.

Abstract: The chill rolls of the cooling section are hollow, open-ended rolls. Spray nozzles in each roll spray water on the instantaneously upper half of the interior periphery and a fan blows air through the roll to effect evaporative cooling. Three different arrangements of the spray nozzles are disclosed for always directing spray to only the upper half of each chill roll.

Abstract: Apparatus for depositing granules comprising feeders adapted to discharge responsive to a signal transmitter, the reception of the signal being interrupted by a moving tape, a plurality of such apparatus being employed to eliminate patterning on roofing shingles. A random signal generator may be used.

Abstract: A method and apparatus for applying granules to continuously moving strip asphaltic material comprises discharging granules onto tacky strip asphaltic material, continuously removing the non-adhered portion of the granules, sensing the amount of removed granules, and controlling the amount of granules discharged onto the asphaltic material in response to the sensed amount of removed granules.

Abstract: A method and apparatus for cooling a continuously moving strip of asphaltic material includes directing the asphaltic material into a plurality of loops, spraying an evaporative liquid onto the asphaltic material, evaporating the evaporative liquid by causing an array of air jets to impinge on the asphaltic material subtantially normally to the asphaltic material, sensing the surface moisture of the asphaltic material subsequent to one or more of the loops, and modifying the flow of evaporative liquid sprayed in one or more of the loops in response to the sensed surface moisture.
