    摘要: A cathode ray display tube has a mild steel envelope part (10) with a tubular copper pump stem (20) sealingly attached thereto by friction welding. A method of attaching the pump stem involves forming the pump stem initially with a closed end, rotating the pump stem relative to and against the mild steel envelope part and applying pressure to cause friction welding of the pump stem, and thereafter extending the pump stem's bore through its closed end by drilling. A hole may simultaneously be drilled through the envelope part. The friction weld provides reliable vacuum-tightness and strength, and the attachment of the pump stem in this manner can be accomplished using automation quickly and inexpensively.

    摘要: An installation for determining the spatial coordinates of a point (P) on a piece (7) in particular for controlling a plant such as a welding plant for car bodies of motor vehicles. The installation is characterized in that it comprises a head (11) movable in a plane (X-Y) and produces a signal as a function of the distance of the point (P) in relation to the plane (X-Y), a rotor (13) on the head (11), this rotor comprising means for projecting a rotating laser beam (21.sub.4), at least three fixed targets (Q, R, S) arranged in the plane (X-Y) and the coordinates of which in this plane are known, these targets being capable of producing a signal as a function of the position (X.sub.P -Y.sub.P) of the head (11) and hence of the point to be measured (P) in the plane (X-Y). The invention is applicable to an installation for determining the spatial coordinates of a point.

    摘要: An energy-beam welding machine has a vacuum chamber consisting of upper and lower parts. For receiving workpieces of various heights, the lower part of the chamber can be lowered to a position below a conveying plane in which the workpieces can be advanced and a lifting column which carries a workpiece-receiving device at its upper end is movable in the vertical direction relative to the lower part of the chamber. The extent of the relative movement can be varied by a displaceable stop between the lifting column and the lower part of the chamber so that, even when the vertical dimensions of the workpieces differ, the position of the welded seams is always in the same plane, and the lower faces of the workpieces can also always be introduced laterally into the lower part of the chamber from the conveying plane.

    摘要: A machine tool (10) for removing metal from a workpiece (20) including a laser (14) for surface heat treating of the workpiece (20). Tools which engage the workpiece (20) for metal removal are supported by a tool turret (26) which is movable along two axes with respect to the workpiece (20) to bring tools into position for metal removal. The laser beam output is connected by beam directing assembly (48), including a telescoping tube arrangement, to a focusing head (60) which can focus the laser beam. The focusing head (60) can be engaged and positioned by the tool turret (26). Tool turret (26) is positioned to maintain the laser beam slightly defocused on the workpiece. A coating spray nozzle (62) is positioned with the laser head (60) and is used for coating the workpiece (20) before laser heat treating. A locking mechanism is provided for locking the head (60) to the beam directing assembly (48). When not being used for heat treating the beam directing assembly, (48) along with the locked focusing head (60) is retracted to a home position. When in the home position a protective cover (90) is positioned over the beam directing assembly. The laser beam is delivered thru telescoping protective tubes by reflective mirrors, which allows the focusing head (60) and directed laser beam to follow motion of the tool turret (26). Flexible connections are provided for connecting the necessary air, water, and coating to the various beam delivery and coating members.

    摘要: Method and apparatus for drilling holes with a laser comprising a support member carrying an insulating sheet which supports a metal plate in which holes are to be drilled by a laser. The insulating sheet serves to blow molten metal out of the holes as they are formed and prevents metal from depositing on the plate around the holes.

    摘要: A laser apparatus for use in laser cutting of a plurality of sheets of smoke-sensitive, heat-sensitive material in aligned stacked relation, the apparatus including a base member assembly for producing a magnetic field and for supporting the stack with a template formed of a generally rigid, magnetic material, the pull of the magnetic field on the template urging adjacent sheets into intimate surface contact to substantially eliminate voids therebetween during the cutting process. The template is preferably plated or coated with a reflective substance such as chromium, and the magnetic field may be created by an array of permanent magnets on a magnetic sheet.
