Publication number: 20240092438Abstract: A tunnel operation robot includes a robot body, a walking module, a fixed wing module and a plurality of rotatable wing modules. Both sides of the robot body are provided with cantilever parts, which are collinearly arranged. The walking module is arranged on the robot body. The fixed wing module includes a fixed fan, is fixedly arranged on the robot body, and is configured to provide a pressure for the walking module to be attached to and pressed against the tunnel wall surface. The plurality of rotatable wing modules are respectively arranged on the cantilever parts on both sides of the robot body, and include a rotatable rotating fan and a wind direction adjustment driver. Each rotating fan has a rotation axis parallel to the cantilever parts and an air outlet direction perpendicular to the cantilever parts, and the wind direction adjustment driver is connected to the rotating fan.Type: ApplicationFiled: September 18, 2023Publication date: March 21, 2024Applicants: China Railway Design Corporation (CRDC), TSDI(Tianjin)Testing Technology Co., LtdInventors: Hu CAO, Pan HUANG, Bo LI, Ji ZHANG, ChunShan REN, ShiQi LIU, Yin WANG, ZhiHua LI, MingFeng HE

Patent number: 7928268Abstract: The present invention relates to a process for producing a 2-fluoro-6-halophenol as an intermediate; a process for producing a 2-alkoxy-3-fluorophenol and further a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; a second process for producing a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; and a 2-alkoxy-3-fluorophenol. The 2-fluoro-6-halophenol can be obtained using a 2-fluorophenol as a starting material and through a sulfonation reaction, a halogenation reaction, and a deprotection reaction. The 2-fluoro-6-halophenol is alkyl-etherified, and subsequently the halogen atom is converted into a hydroxyl group to obtain the 2-alkoxy-3-fluorophenol, which is further alkyl-etherified to thereby obtain the 1,2-dialkoxy-3-fluorobenzene. Alternatively, a 1,2-dialkoxy-3-fluorobenzene is also obtained by converting the halogen atom of the 2-fluoro-6-halophenol into a hydroxyl group to thereby form 3-fluorocatechol and subsequently alkyl-etherifying two hydroxyl groups thereof.Type: GrantFiled: July 14, 2010Date of Patent: April 19, 2011Assignees: Asahi Glass Company, Limited, Charna Chemicals Ltd.Inventors: Mingjian Qiu, Wei Zhang, Zhaohui Chen, Chunshan Zhang, Yali Zhang

Patent number: 7185335Abstract: A plugable framework for use in the installation and uninstallation of a suite of applications. An application installer configured according to the plugable framework can include installation logic configured to copy application files to a target computing system. The installation logic also can configure the target for operation with the application. Installation diagnostic and cleanup logic can be coupled to the installation logic. The installation diagnostic logic can detect an installation failure, while the cleanup logic can remove the copied files and can reverse the configuration in response to the installation diagnostic logic detecting an installation failure. Uninstallation logic can be configured both to remove copied files from the target, and also to reverse the configuration of the target according to the terms of a specified uninstallation configuration file.Type: GrantFiled: September 19, 2002Date of Patent: February 27, 2007Assignee: International Business Machines CorporationInventors: John R.
