The preparing step comprises preparing a multi-axis machine tool, a laser displacement meter, an auto scraping apparatus and a computer. The scanning step comprises scanning the work piece. The flatness-parameter inputting step comprises inputting a flatness-parameter. The surface-finishing step comprises calculating out the to-be-scraped ranges of the work piece and scraping the work piece. The related-parameter inputting step comprises inputting desired PPI and POP in the computer, calculating out the HOP, the DOS and the oil content to obtain the length, the width and the depth of a single scraping process. The auto-scraping step comprises scraping the work piece to meet the requirement. The analyzing step comprises detecting the 3D-appearance drawing of the work piece.

Abstract: A novel composition is provided that incorporates the residual solids from solvent deasphalting to make a high value asphalt product. A process for making the asphalt composition is also provided. A first portion of heavy oil or another feedstock can be deasphalted using propane deasphalting or another suitable deasphalting process. This generates a solvated fraction and an insoluble deasphalting residue. The deasphalting residue is then added to a second portion of heavy oil, such as a second portion of the same type of heavy oil that was used as feedstock in the solvent deasphalting. The mixture of deasphalting residue and heavy oil results in a novel dispersion that is suitable for use as an asphalt. Optionally, an additive such as an alkyl substituted aromatic sulfonic acid can be added to the composition to further improve the asphalt properties.

Abstract: A power line testing device has a signal generator that is adapted to be connected to one of a plurality of AC branch circuits, and generates an identification signal. This identification signal will be strongest in the branch circuit of origin. A receiver of the testing device senses the strength of the identification signal, compares that strength to a stored identification signal, and is therefore able to identify to which AC branch circuit the transmitter is connected.

Abstract: Disclosed is a method of manufacturing briquettes of reduced iron, wherein a residual oil on distillation containing petroleum asphalt or petroleum pitch is sprayed on the surfaces of rolls. The petroleum asphalt or petroleum pitch are thermally cracked into hydrocarbon gas and carbon by the heat (650.degree. to 750.degree. C.) of the reduced ion. This makes it possible to prevent briquettes from sticking on roll pockets, and hence to provide stable operation of the briquette manufacturing apparatus.
