IPC: C10B27/00
Filed: 1984-11-17
Abstract: PURPOSE:To facilitate fractional recovery of tar by recovering tar of a high quinoline insolubles content in the initial period of carbonization after coal feeding and in the terminal period of carbonization before completion of carbonization, and recovering tar of a low quinoline insolubles content in the intermediate period of carbonization. CONSTITUTION:Coal is fed to a coke oven. Tar of a high quinoline insolubles level is recovered in the initial period of carbonization after coal feeding and in the terminal period of carbonization before completion of carbonization when the tar generated from the coke oven is of a high quinoline insolubles level. Tar of a low quinoline insolubles level is recovered in the intermediate period of carbonization when the tar generated from the coke oven is of a low quinoline insolubles level.

IPC: B23K26/08
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To perform simply, quickly and accurately the positioning of an object to be machined in a marking device. SOLUTION: A controller, entering a 'marking area projection' mode, first identifies a selected start-up number, and then retrieves plotting data of the marking area corresponding to this start-up number. Next, with an He-Ne laser actuated, a visible (red) guide beam is turned on. Then, a control signal corresponding to the retrieved plotting data and conditions data is transmitted to a scanning head, with the beam spot of the guide beam scanned once on the surface of an object to be machined, and with the marking area plotted that is related to the pattern of this start-up number. This scanning operation is continuously repeated until a prescribed command is inputted.  Thus, the plotting of the marking area is repeated continuously at high speed; also, with a human visual after-image effect added, a standing projection image of the marking area is formed on the surface of the object to be machined.
