Publication number: 20120181220Abstract: Deasphalted residual oil (DAO) and the aromatics-rich extract that is derived from DAO have low polycyclic aromatics contents, relatively low aniline points, and high flash points. They form blending stocks that improve properties of mixed feedstocks to consistently produce environmentally qualified rubber processing oil (RPO) by extraction under low solvent-to-oil ratios and moderate extraction temperatures. Distilling a petroleum crude oil under atmospheric pressure generates a bottom residual oil which is then subject to vacuum distillation to yield a bottom residual oil. DAO is produced by removing the asphalt from the vacuum bottom residual oil through extraction with light paraffinic solvent. The extract of DAO is a co-product in the production of the bright stock of the lubricating oil through extraction. The feedstock is mixed with the extract from a petroleum fraction boiling in lube oil range.Type: ApplicationFiled: January 14, 2011Publication date: July 19, 2012Applicant: CPC Corporation TaiwanInventors: Chih-Cheng Chang, Jung-Huang Wu, Cheng-Tsung Hong, Jin-Shang Liou, Kuo-Min Wei, Hung-Chung Shen, Fu-Ming Lee

Patent number: 8045067Abstract: A method for searching a frequency band to locate a channel. The method includes the steps of setting an initial frequency and a first frequency step; determining a frequency point based on the initial frequency and the first frequency step; determining whether the frequency point satisfies a first condition, which is continuously detecting a horizontal signal a predetermined number of times. When the first condition is satisfied, the frequency point is recorded as an entrance point. A second frequency step based on the entrance point determines a second frequency point, wherein the second frequency step is less than the first frequency step. It is then determined if a channel exists at the second frequency point. The entrance point is recorded as the updated initial frequency for the next search. The described steps are repeated for the entire frequency band.Type: GrantFiled: November 5, 2007Date of Patent: October 25, 2011Assignee: AU Optronics Corp.Inventors: Chih-Cheng Chang, Ming-Che Tan
