Abstract: Described is a device that is useful for allowing an engraver, or the like, to have their workpiece rotated without the need to lift their tools from the work piece, and to eliminate hesitation or stopping in the course of engraving circles, spirals, curves, or convoluted shapes. The device is a workstation, such as used by engravers, welders and the like, that comprises a workbench upon which a turntable is mounted. The preferable turntable is mounted to the top of a rotatable post, which projects through the workbench by means of an extension piece. The post is in turn attached to the underside of the workbench and also to the floor (or base plate or other suitably rigid structure such as the workbench or stand) using flanged bearings. Attached to a portion of the post near the floor is a foot operated plate. The operated plate is located in a position such that it is conveniently accessible by a foot of the engraver.

Abstract: A system for cloning input/output (I/O) devices connected to a network hosting an industrial control system includes a first network coupled to a second network. A first plurality of I/O devices are connected to the first network. A second plurality of I/O devices are connected to the second network. A master computer is coupled to one of the first and second networks and includes control software with an object oriented model for defining attributes and operations of the I/O devices on the first network to allow cloning of the I/O devices onto the second network. The object oriented model includes a hierarchical class structure with inheritance. The hierarchical class structure includes a device class and a plurality of device types. The object oriented model includes at least one class level hierarchically below the device class. Devices instantiated at a class level inherit the attributes or operations of the class level.
