  • Patent number: 7542311
    Abstract: A method for operating a converter circuit is specified with the converter circuit having a converter unit with a multiplicity of controllable power semiconductor switches and having an energy storage circuit formed by two series-connected capacitors, in which the controllable power semiconductor switches are controlled by means of a control signal formed from a hysteresis signal vector (x), and the hysteresis signal vector (x) is formed from a difference-phase connection current vector (?ifi,i) by means of a hysteresis regulator, and the difference-phase connection current vector (?ifi,i) is formed from the subtraction of a phase connection current vector (ifi,i) from a reference phase connection current vector (ifi,i,ref), with the reference phase connection current vector (ifi,i,ref) being formed from a difference power value (Pdiff), a difference wattless-component value (Qdiff) and a phase flux vector (?g,??).

  • Patent number: 6929440
    Abstract: The invention relates to a particularly effective method for loading and unloading loads in a rack storage facility with several rack bays and aisles which are located between the rack bays. According to the method, a load is transported to a front end of a rack bay and at the front end of the rack bay, is moved in a vertical direction to a target level. The load is then moved into the aisle in a horizontal direction, at the target level. The load is moved in the aisle to a target location at the corresponding target level and then finally out of the aisle and into the rack in a horizontal direction. The invention also relates to a storage loading system for carrying out the inventive method. According to this method, several guiding elements corresponding to the individual levels of the rack bays are provided in the aisles. Moveable transport devices for receiving loads are provided on the guiding elements.

  • Publication number: 20040220843
    Abstract: In an integrated method for sustained business improvement, an overall loop is repeatedly and continuously executed for the ultimate purpose of identifying processes within a business and comparing those processes to objective standards of excellence. By continuously and repeatedly executing the overall loop, it is assured that sustained business development will be achieved. The overall loop includes individual loops, which are respectively executed to generate a business map, a business roadmap, a business drive map, a process map, an object map, an organization map, a data map, an information map, a performance map and an excellence map.

  • Patent number: 6580621
    Abstract: The three-phase hybrid ac-voltage/ac-voltage direct converter includes two symmetrical interruptible electronics witches. Each switch includes only one power transistor and a one-phase diode bridge. As a result, only 12 power transistors are required to realize the overall system. During the changeover of a positive input terminal from one system phase to system, an output section is temporarily switched to a free-wheeling state.

  • Patent number: 4090857
    Abstract: A filter box for textile machines, especially spinning machines, comprising a filter subdividing a box into a raw air chamber and a clean air chamber, and a respective inlet opening and outlet opening communicating or connected with the raw air chamber. A ventilator is connected at its suction side with the clean air chamber. The filter possesses a cylindrical form and the inlet opening is formed by an inlet connection extending approximately tangentially with respect to the filter, in order to produce a spin flow in the raw air chamber.

  • Patent number: 4045194
    Abstract: An apparatus for cleaning air charged with contaminants, especially fibers and dust, comprising a pre-separator and a dust filter arranged after the pre-separator. At least one movable suction nozzle is effective at the surface of the dust filter. The pre-separator, constructed as a body of rotation, possesses an inlet portion structured for producing a spin flow and a jacket portion structured as a sieve surface which is surrounded by a rotatably mounted filter drum of the dust filter. A cylindrical filter body of the filter drum has operatively associated therewith at the inner surface thereof the movable suction nozzle, and drive means are operatively connected with the suction nozzle and filter drum.
