  • Patent number: 11955882
    Abstract: An active discharge circuit for electric vehicle inverter, the active discharge circuit intended to be connected in parallel with a DC link capacitor connected between positive and negative lines of a DC power link, wherein the circuit comprises a dissipative current source, a switch connected in series with the current source between the DC lines, and a controller connected to the switch and arranged to apply an activation signal in dependence of a control signal, the activation signal placing the switch in a conducting state, wherein the current source is configured to draw a discharge current and dissipate any energy stored in the DC link capacitor when the switch is in the conducting state. As long as the switch is closed by the activation signal, the current source will draw a constant current and dissipate power, and the voltage across the DC link capacitor will decrease linearly.

  • Patent number: 7384674
    Abstract: A packaging laminate for a retortable packaging container, the packaging laminate (30) including a paper or paperboard layer (31), outer, liquid-tight coatings (32; 33) and an aluminium foil (34) serving as gas barrier between the paper or paperboard layer (31) and one of the two outer liquid-tight coatings (32). In order to compensate for or counteract possible loss of gas tightness because of crack formations or similar untightness in the tensile-sensitive aluminium foil (34), the packaging laminate (30) includes at least one additional layer (35) serving as gas barrier between the paper or paperboard layer (31) and the aluminium foil (34).

  • Patent number: 7195803
    Abstract: The disclosure relates to a packaging laminate for a retortable packaging container comprising a core layer (11), outer, liquid-tight coatings (12 and 13) and a gas barrier (14) disposed between the one coating (12) and the core layer (11). Between the gas barrier (14) and the core layer (11), there is a layer (16) of a lamination or sealing agent of such a nature that the lamination or sealing agent has a melting point which is higher than the maximum temperature to which the retortable packaging container is to be subjected during a normal heat treatment in a retort. The lamination or sealing agent in the layer (16) may, for example, be a polypropylene with a melting point of above 130° C.

  • Patent number: 6468382
    Abstract: Packing material with good gas barrier properties comprising a first and a second layer of a fibrous material or, e.g. paper or cardboard, and a layer of a water based polymer, e.g. polyvinyl alcohol, placed between and in direct contact with the layers of fibrous material and functioning both as a gas barrier and as a binding agent in the packaging material. The packaging material is produced through bringing together and binding together with each other a first and a second strip or sheet of a fibrous material by means of a layer of a water based polymer, e.g polyvinyl alcohol, applied between and in direct contact with the strips or sheets. The surplus water in the thus applied polymer layer is absorbed by the fibrous material in one and/or the other strip or sheet to form the intermediate layer functioning as gas barrier and binding agent.
