7. A digital camera device which includes an integrated circuit as claimed in claim 1.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A machine for welding rails of a track, the rails extending in a longitudinal direction and resting on ties, the machine comprising:
a machine frame having on-track undercarriages for mobility on the track;
a rail pulling device for gripping rail ends to be welded to one another, said rail pulling device being fastened for vertical adjustment to said machine frame;
clamping members mounted to said rail pulling device and pivotally about mutually parallel pivot axes, said clamping members forming two pairs of clamping members, spaced from one another in the longitudinal direction, and having clamping jaws for gripping the rail;
hydraulic drives connecting said two pairs of clamping members to one another;
two rail clamps for gripping and lifting the rail ends from the ties, and an adjustment drive for vertically adjusting each of said rail clamps independently of said rail pulling device; and
a welding unit for welding the rails.
2. The machine according to claim 1, wherein said rail pulling device includes two transverse beams, and wherein each of said rail clamps is fastened to a respective one of said transverse beams and is adjustable by way of said adjustment drive relative to said transverse beam in a direction extending perpendicularly to a pulling device plane formed by a position of said clamping members.
3. The machine according to claim 2, wherein each one of said rail clamps is disposed symmetrically with respect to a plane of symmetry extending perpendicularly to the pulling device plane and centrally between said pivot axes of each pair of clamping members.
4. The machine according to claim 2, wherein an upper end position of said rail clamps is delimited by the pulling device plane.
5. A method of welding rails of a track, the rails having rail ends resting on ties, the method which comprises:
a) gripping the rail ends to be welded to one another by way of rail clamps, lifting the rail ends to distance the rail ends from the ties, and delivering the rail ends to clamping members of a rail pulling device;
b) firmly clamping the rail ends with the clamping members when the rail ends come to lie between the clamping members, and opening the rail clamps; and
c) pulling the rail ends towards one another and welding the rails.
