Abstract: An induction heating device having two superimposed conductors is provided, comprising a first conductor having a first electrically conducting pattern; a second conductor having a second electrically conducting pattern; wherein the first electrically conducting pattern and the second electrically conducting pattern are: i) connected to an alternating current in use; ii) superimposed thereby resulting in at least one section where the first electrically conducting pattern overlaps the second electrically conducting pattern; and iii) separated by at least a space arranged for accommodating material with an electrically conducting layer, wherein when the alternating current is supplied, the alternating current in the first electrically conducting pattern in a specific section has the same direction as the alternating current of the second electrically conducting pattern in said section.

Abstract: An arrangement is provided to prevent emissions of hydrogen peroxide from a packaging machine forming sealed packaging containers from a packaging material web. The packaging machine has a sterilization portion comprising an inlet chamber, a peroxide bath and an aseptic chamber. The aseptic chamber is held at an overpressure while the inlet chamber is held at an underpressure during normal operation of the packaging machine. The peroxide bath functions as a seal between the inlet chamber and the aseptic chamber. A safety chamber placed in front of the inlet chamber is held at an underpressure to avoid peroxide emissions to the environment. The packaging material web will pass the safety chamber before going into the inlet chamber.

Abstract: On extracting, reeling up, pulling in etc., of a heavy cable a main frame that can be set up or that may already be present on a vehicle may be used. The main frame comprises a base unit made up of a number of beams, and two bearing brackets projecting upwards from its long sides. A drum for the cable is supported free to rotate on the bearing brackets. The drum is provided with drive gear which comprises a motor unit and a transmission component. A pulling device is connected to a core of the cable and to a pull-free mechanism secured to the main frame. By means of the pull-free mechanism the cable can be given a small longitudinal displacement which enables the cable to be pulled free of its duct. After pulling free the pulling device is disconnected and the cable is pulled up towards and anchored on the drum, after which the motor unit is operated to turn the drum. The major part of the longitudinal displacement of the cable is then achieved by reeling the cable directly up on to the drum.
