20150048146 | METHOD FOR PRODUCING WELDED TUBES FROM STEEL - In a method for producing welded pipes from steel, in which strips or metal sheets are formed into a pipe provided with a longitudinal or helical slot and the abutting edges of the slotted pipe are welded together, the process parameters for production of the pipes are specified on the basis of previously ascertained material properties and geometry of the strips or metal sheets. Before the forming process, the strip or metal sheet is subjected to an nondestructive, continuous or discontinuous test for inhomogeneities over the length and width, an integral characteristic value for the material property of the strip or metal sheet is formed from the measured values, a measure of the homogeneity of the material properties relating to the length and width of the strip or metal sheet is derived from the variance in the measured values for the various measurement points and, in the event of deviations in the measured values exceeding previously specified limit values, the process parameters are reset and/or the strip or metal sheet is subjected to a homogenisation process prior to the forming process. | 02-19-2015 |

20100220508 | Photovoltaic Inverter with Option for Switching Between a Power Supply System with a Fixed Frequency and a Load Variable Frequency - A photovoltaic inverter having an inverter bridge section, a first output, a second output, and a power switch. The inverter bridge section is operable for converting DC electrical energy into AC electrical energy. The inverter bridge section has an output for outputting the AC electrical energy. The power switch is connected to the output of the inverter bridge section, the first output, and the second output. The power switch is selectively switchable between a first state in which the output of the inverter bridge section is connected to the first output via the power switch and a second state in which the output of the inverter bridge section is connected to the second output via the power switch. | 09-02-2010 |

20080249532 | Securing device to secure fixation devices to bone portions - The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant, and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform, single movement as opposed to currently available products. The securing device has two handles pivotably connected, and a gripping means moveably associated with one handle. As the handles are activated, the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place. | 10-09-2008 |
