Abstract: A portable asphalt recycling device comprising: a base; a rotatable drum unit secured to the base; a hopper secured to the rotatable drum unit used to load and unload materials from within the drum unit; a burner secured to the rear of the drum unit to heat the materials; one or more corkscrew fins located within the drum unit, the fins being operable in the mixing and folding of the material and also being operable in pulling the material to the back of the drum unit for complete heating and mixing and pushing the material from the back of the drum unit to the front of the drum unit for unloading; wherein the material within the drum unit does not come into contact with a flame produced by the burner; and a thermostatic heating sensor device located within the drum unit used to measure the temperature of the material.

Abstract: A coping system for parapet is comprised of three separate components, a plurality of cleats, a plurality of chairs and a plurality of caps. The cleats are secured to the parapet at spaced intervals and each cleat supports a corresponding chair. Each cap extends between at least two cleats and chairs. Adjacent caps are spaced from each other forming a gap between the caps with the gap being located directly above the chair. The chair forms a gutter for routing water away from the top of the parapet. The chair biases the cap away from the parapet to maintain the engagement between the cap and the cleat. All three components are made entirely of metal providing a sealed joint between adjacent caps without the use of organic compounds.
