Abstract: Device for the inductive flow-heating of an electrically conductive pumpable medium, whereby there are provided in the device pipeline windings, through which the medium flows, on a magnetic yoke in which with the aid of an inductive alternating current energy transfer in accordance with the transformer principle electric voltages are induced. At least two such pipeline windings are connected with each other via supply distributor and mixer pieces in such a way that a short-circuit current flows in a closed path of the medium in the pipeline windings, fed by the induced voltages, which heats the medium. A further development provides that there are provided heating elements connected with the pipeline windings and adapted in dimensions to these windings, in which heating elements a rapid local heating can be obtained through current density concentration.

Abstract: Apparatus for making and manipulating sheet-like paper, plastic or metallic blanks in a packing machine has a pivotable conveyor with a gripper which pulls the leader of a running web across the path of successive mandrels or cigarette packs on an indexible turret whereby the gripper overcomes the resistance of a mechanical or pneumatic clamping device which holds the leader of the running web in a position in which the leader can be engaged by the gripper when the conveyor completes a return stroke. The running web is severed by a pair of knives which are installed between the clamping device and the gripper and are caused to cut the web when the gripper reaches an end position in which a sufficient length of the running web is moved across the path of an oncoming mandrel or cigarette pack.
