  • Patent number: 9314874
    Abstract: A welding tool is configured with a housing enclosing a fiber laser system which is operative to produce a weld seam for connecting two workpieces. The fiber laser system includes a focusing optic configured to focus the output beam of the system so that it propagates through an elongated slit formed in the bottom of the housing. The fiber laser system is capable to move along a predetermined path extending parallel to the longitudinal direction of the slit and limited by the perimeter thereof. The output beam od generated only when the slit sots upon at least one of the workpieces.

  • Publication number: 20060213130
    Abstract: A system for integrating a garage into the main unit of a manufactured building includes a removable shipping wall defining an first interior space; the removable shipping wall further comprises a removable left extension wall; a removable right extension wall; a removable left garage door wall; and, a removable right garage door wall. The removable left extension wall, the removable right extension wall, the removable left garage door wall, and the removable right garage door wall define a second interior space when the left and right removable extension walls are connected at a substantially right angle to the main unit and the left and right garage door walls are connected at a substantially right angle to the left and right extension walls, respectively. Thus, the first and second interior spaces define a space for the integrated garage.

  • Publication number: 20060213144
    Abstract: A drawbar assembly for transporting a manufactured building comprises an A-frame. The A-frame further comprises two arm beams, each arm beam having first and second ends. The first ends of the arm beams are connected together to form the apex of the A-frame, and the second ends of the arm beams are disposed so that the two arm beams form an acute angle. There are at least first and second cross beams, the first cross beam being connected to the second ends of the arm beams; the second cross beam being connected across the arm beams between the apex of the A-frame and the first cross beam. There are two perimeter beams for supporting a structure; and, the two perimeter beams are removably connected to the cross beams of the A-frame.

  • Publication number: 20050252895
    Abstract: The invention relates to a sensor device for detecting radiation from the region of a zone of interaction (16) between a laser beam and a workpiece (17) for monitoring a laser machining operation and a workpiece, in particular a laser welding operation, and a device for monitoring the laser machining operation, in particular the laser welding operation, and a laser machining head having such a sensor device. The sensor device possesses a radiation-sensitive receiver arrangement and an imaging device which images a region to be observed in the region of a zone of interaction (16) onto the receiver arrangement. In order to achieve a compact and space-saving structure it is provided that the imaging device comprises a focusing mirror arranged in the working beam pathway of the laser beam which diverts radiation from the region to be observed out of the working beam pathway and focuses it onto the receiver arrangement.

  • Publication number: 20040026389
    Abstract: The invention concerns a method which can be carried out with a sensor device, for monitoring a laser machining operation to be performed on a work piece, in which for quality assurance with a local-resolution receiver assembly, a given field of observation is selected in the region of the interaction zone between laser beam and work piece, in which radiation coming from the selected field of observation is detected with a radiation-sensitive receiver which delivers an electrical signal corresponding to the detected radiation, in which the electrical signal is filtered in a signal processing circuit in order to detect rapid and/or short, fault-related changes in intensity of the detected radiation, and in which the filtered electrical signal for the detection of faults during the laser machining operation.
