摘要： A method of planning tasks to be performed in a machine derives a precedence graph by linking subsidiary tasks to a sequence of key tasks to create a scheduling problem that can be solved by an automated scheduler. In the event of a trigger, such as an order for new work or a machine exception, work can be retimed, rescheduled or replanned.
摘要翻译：计划在机器中执行的任务的方法通过将辅助任务链接到一系列关键任务来产生优先图，以创建可由自动调度器解决的调度问题。如果触发事件，例如新工作或机器异常的订单，可以重新计划，重新安排或重新启动工作。

摘要： Scheduling of tasks in a lithographic apparatus, track unit or lithocell is performed by maintaining a register of the state of the machine and a database of tasks performable by the machine, generating possible sequences of tasks based on pre- and post-conditions on the system state (rather than a precedence relation) and selecting a sequence from the generated sequences that meets a given beginning state of the machine and a desired end state. Embodiments of the invention also allow for automated recovery from exceptions.

摘要： A method of and apparatus for treating molten metal to achieve effective removal of such unwanted inclusions as gases, alkali metals, entrained solids, and the like. The method comprises introducing molten metal into a trough, such as the trough provided between a melting furnace and a casting machine, providing at least one mechanically movable gas injector submerged within the metal in the trough and injecting a gas into the metal in a part of the trough forming a treatment zone through the injector(s) to form gas bubbles in the metal while moving the injector(s) mechanically to minimize bubble size and maximize distribution of the gas within the metal. The injectors are preferably rotated and comprise a rotor body having a cylindrical side surface and a bottom surface, at least three openings in the side surface spaced symmetrically around the rotor body, at least one opening in the bottom surface, and at least one internal passageway for gas delivery and an internal structure for interconnecting the openings in the side surface, the openings in the bottom surface and the internal passageway. The internal structure is adapted to cause gas bubbles emanating from the internal passageway to break up into finer bubbles and to cause a metal/gas mixture to issue from the openings in the side surface in a generally horizontal and radial manner.

摘要： A method of and apparatus for treating molten metal to achieve effective removal of such unwanted inclusions as gases, alkali metals, entrained solids, and the like. The method comprises continuously introducing molten metal into a container forming a trough or trough section, such as the trough provided between a melting furnace and a casting machine, providing at least one mechanically movable gas dispenser submerged within the metal in the container and introducing a gas into the metal adjacent to the gas disperser in a part of the trough forming a treatment zone such that the gas is broken into smaller bubbles by the gas dispenser and dispersed through the treatment zone. The trough or trough section is such that it exhibits a static to dynamic metal holdup of less than 50%.
