20120087726 | Electric Screed Heat Control System and Method of Heating Screed Plates - In electrically heated screed assemblies, elements that are prone to failure are the temperature sensors. Typically, each screed plate has a single temperature sensor. When one temperature sensor fails, the controller will look for a working temperature sensor amongst the other screed plates and if more than one temperature sensor is working, the controller will choose the most relevant temperature sensor and use the data from the working temperature sensor to operate the resistive heating elements on the screed plate with the non-functional temperature sensor. If the temperature sensor on an outer screed plate fails, the controller will look to the other outer screed plate temperature sensor for data for purposes of operating the resistive heating elements on the outer screed plate with a broken temperature sensor. Similarly, if the temperature sensor on an inner or central screed plate fails, the controller will look to a neighboring screed plate with a working temperature sensor for data for purposes of operating the inner or center screed plate with the broken temperature sensor. The controller will generate signals for the operator to replace the failed temperature sensor. | 04-12-2012 |

20120301222 | PATCHING MATERIAL USING POWDER COATING PAINT AND METHOD OF USING - A product and method for repairing holes and cracks in roads, parking lots, sidewalks and other similar surfaces using a mixture of powder coating (i.e. dry paint) and a filler. The first step is to obtain the powder coating material. Any suitable powder coating material may be used, however, it is preferable to use the excess or waste powder coating material obtained from a powder coating operation. The next step is to mix the powder coating material with a filler, such as sand, pea gravel, or another suitable material. After the components are mixed together, it is applied to a surface needing repair such as a pothole in a road or a crack in a sidewalk. The mixture is cured by heating the mixture to the point where the powder coating melts and binds the powder coating with the filler and the surface needing repair. It may be cured before or after it is applied to the surface needing repair. After the mixture cures, the result is a high quality patched surface. | 11-29-2012 |
