20120111114 | Method and Apparatus for Determining an Operating Point of a Work Machine - Method and apparatus for determining an operating point of a work machine and/or asynchronous motor driving the same, the operating point being characterized by the power consumed by and/or output rate of the machine, in which one or more operating point-dependent measurement variables of the machine are detected by sensors, and the measured values are evaluated and/or stored during operation of the machine. The operating point is determined without using electric measurement variables of the motor by determining a frequency linearly proportional to the fundamental tone of the machine through signal analysis, especially frequency analysis of a measured mechanical variable selected from pressure, differential pressure, power, vibration, and solid-borne or air-borne sound. From this, the rotational speed of the driving machine is determined, and the operating point characterized by the power consumed by and/or output rate of the machine is determined utilizing the rotational speed/torque relationship of the motor. | 05-10-2012 |

The trigger bar moves in response to a pulling of a trigger. An actuator in said firearm is adapted to actively move said trigger bar between a first position and a second position. The trigger bar engages in the trigger induced movement with a hammer link for releasing a hammer and firing a cartridge bullet when the trigger bar is in the first position or first state. However, said trigger bar does not engage in the trigger induced movement with the hammer link, such that the cartridge bullet is not fired, when the trigger bar is in the second position or state. | 03-17-2011 |
20110107638 | Hand gun - The present invention relates to a hand gun having at least one exchangeable magazine for cartridges, able to be inserted from below into a grip piece of the weapon.
