Abstract: An automatic synchronizer 20 includes a throttle rod 62 which provides a direct link between the slave motor throttle lever 44 and the slave motor 36. A microprocessor system 30 provides a signal to a bi-directional synchronization motor 58 dependent on the difference in speed between a master reference motor 34 and the slave motor 36. Depending on this signal, the synchronization motor 58 positions the throttle rod 62 in order to directly effect the speed of the slave motor 36 and to reposition the slave motor throttle lever 44 to a position appropriate to the speed of the slave motor 36. Once synchronization has occurred, an electrically operated clutch 60 is deactivated such that a normal force will move the slave throttle lever 44.

Abstract: A material working tool 10 includes a device for working material 18 and a base 12 for supporting the device 18 for working the material. The base 12 includes a rigid member 26 and a cavity 54 defined in the rigid member 26 which is connected to a source of vacuum. A seal 66 is provided about the bottom surface 56 of the rigid member 26. The seal 66 is compressed as a vacuum is created in the cavity 54 so that the rigid member 26 comes into contact with the surface of the working material allowing for the accurate positioning of the material working tool 10 relative to the material to be worked.
