  • Publication number: 20220288727
    Abstract: A method for transporting workpiece parts out of a cutting area of a laser cutting machine includes: moving a first holding device for holding workpiece parts along a first guide in a transporting direction transverse to a direction of movement of a laser cutting head, and moving a second holding device along a second guide in the transporting direction transverse to the direction of movement of the laser cutting head. First workpiece parts, which are cut within the cutting area from a first half of a workpiece, are transported from the cutting area into the storage area by the first holding device. Second workpiece parts, which are cut within the cutting area from a second half of the workpiece, are transported from the cutting area into storage area by the second holding device. The transportation of the first and second workpiece parts takes place in alternation.

  • Patent number: 11441518
    Abstract: A carburetor has a carburetor body wherein an intake channel is formed. A throttle flap is pivotably mounted by a throttle shaft in the carburetor body for controlling the free flow cross-section of the intake channel. The intake channel has a first longitudinal center axis in the region of the throttle shaft. The throttle flap has first and second end positions, wherein the throttle flap opens a larger flow cross-section of the intake channel in the second end position than in the first end position. A partition wall section, on which the throttle flap lies in the second end position, is arranged upstream of the throttle shaft. A choke flap is upstream of the partition wall section and is pivotable between first and second end positions. In their second end positions, the throttle flap and the choke flap overlap in the direction of the first longitudinal center axis.

  • Patent number: 9065345
    Abstract: A transformerless inverter that serves to feed electricity from a DC current source into an AC power grid, has an inverter bridge and a DC/DC converter connected upstream of the inverter bridge. The DC/DC converter converts an input DC voltage that is present between two input lines of the inverter into a DC link voltage present between two input lines of the inverter bridge. The inverter bridge converts the DC link voltage present at the input lines thereof into an output AC voltage. The DC/DC converter includes at least one resonant circuit that has a resonance inductance and a resonance capacitance and is connected on its input side via at least two clocked switches to one of the two input lines of the inverter or an intermediate potential line carrying a potential in between. The input lines of the inverter and the input lines of the inverter bridge are galvanically isolated from one another by a capacitive method.

  • Patent number: RE44901
    Abstract: A method of converting a direct voltage generated by a decentralized power supply system into three-phase alternating voltage by means of a plurality of single-phase inverters (WR1-WR3), said alternating voltage being provided for supplying an electric mains, is intended to avoid inadmissible load unbalances using single-phase inverters. This is achieved in that, upon failure of one inverter (WR1-WR3), an asymmetrical power supply distribution is reduced by limiting the output of the other inverters. The method makes it possible to simplify three-phase voltage monitoring.
