  • SWTICHING PHASE OFFSET FOR CONTACTOR OPTIMIZATION
    Publication number: 20120299395
    Abstract: A system and methods providing for minimizing the arc energy delivered to the pads of a plurality of contactors using a single control coil based on monitoring the electrical sine waves of the three alternating current electrical poles and calculating the instant to energize or deenergize a single control coil. The remainder of the contactors will make or break based on an offset in time from the making or breaking of the control contactor.
    Type: Application

  • Laser machining apparatus and method for forming a surface on an unifinished product
    Publication number: 20110095005
    Abstract: The invention concerns a method and an apparatus for the laser machining of an unfinished object (27). The unfinished object (27) is to be formed into a cutting tool with a cutting edge (60) and a free surface (62). A laser is provided which generates laser beam impulses (24) which are directed by a redirecting arrangement (23) onto a surface (26) of the unfinished object (27). A laser beam impulse (24) reaches at an impact location the surface (26) of the unfinished object (27) under an inclination angle between the laser beam direction (R) of the laser beam impulse (24) and the surface (62) to be formed on the unfinished object (27). The redirecting arrangement (23) is controlled in such a way that the laser beam impulses (24) impact at adjacent impact locations on form and form a pulse zone (55).
