Abstract: A roof, wall or façade structure suitable for new flat or pitched roofs, or renovation or reconstruction thereof, to a kit of parts for constructing, reconstructing or renovating a roof, wall or façade structure and a method for constructing or reconstructing a roof, wall or façade structure.

Abstract: A locking device and a locking method are provided for a tool holder of a rotary drilling rig. The locking device includes a sleeve, a locking pin, a movement system, and a control system. The sleeve and the locking pin are configured such that the sleeve engages around the locking pin with a form fit, such that the locking pin can be rotated in the sleeve about the longitudinal axis of the locking pin. As a result, the locking pin can be displaced laterally parallel to the longitudinal axis. The movement system has at least one electric motor and at least one shaft, wherein the shaft effects relative rotation of the sleeve and the locking pin by the force of the electric motor.

Abstract: A method of coating a surface expected to come in contact with liquid metal particularly steel under utilization of combusting gases and producing a soot layer possibly under reducing conditions is improved by a post deposit treatment including a flame which may oxidize but does not reduce the soot layer for reducing the size of the particles to thereby compact, strengthen and increase adhesion of the layer.

Abstract: A flame cutting machine for subdividing a steel strand or the like is constructed to be movable on rails on both sides of a roller table supporting the strand with a measuring roller for determining the linear measurement of the strand; the measuring roller is tilted on a lever affixed to the machine carriage and is unilaterally open with its axis being in a vertical disposition.

Abstract: A flame cutting machine for subdividing continuously prepared poured casting strands or the like includes an essentially closed suction head in the cutting zone which is mounted movable together with the flame cutting machine for removal of smoke gases, slag and the like produced during the cutting process.

Abstract: A device for linearly measuring a hot work piece includes a measuring roller for contacting the underside of the work piece with the roller mounted on a shaft in a tilting arrangement. A water supply is provided on the shaft communicating with a channel which extends into the roller and with the roller being open on at least one side thereof.

Abstract: A device for positioning a cutting torch aggregate includes a movable sled for carrying the torch. The sled is connected by means of a spindle to an adjustable drive which is activated by its engagement with a nut which mounts the sled to the spindle. The nut activates a control for the drive.

Abstract: A cutting machine for separating workpieces includes a cutting unit which is mounted above a workpiece to traverse the width of the workpiece and cut therethrough. The mounting means includes rails disposed over and across the workpiece over which the cutting unit travels and a workpiece clamping mechanism for securing the cutting unit to a fixed position along the length of the workpiece. The clamping mechanism includes a pair of opposed levers for movement into and out of engaging contact with the workpiece. In accordance with the invention adjustable stop means are provided to limit the movement of the clamping levers away from the workpiece so as to minimize the movement later required for re-engagement with the workpiece.
