  • Retention of PBO in polymer matrices by phthalocyanines
    Patent number: 8936801
    Abstract: By incorporating PBO and phtalocyanine in a polymeric matrix, the surface concentration of the PBO after migration to the surface is reduced relatively to a matrix without phtalocyanine. This can be used to control the migration of PBO and retain PBO for a long-lasting effect.

  • Drinking straw with Hollow Fibre Liquid Filter
    Publication number: 20120298583
    Abstract: A liquid filtration method and device, for example a drinking straw with a mouthpiece, and a bundle of hollow fibres. The open ends of the fibres are embedded in a base and provided in a compartment between the base and a liquid outlet. Water or other liquid flows into the inner volume of the hollow fibres and from there through their filtering membrane walls and into the compartment before the liquid flows out through the liquid outlet, for example the mouthpiece.

  • Insecticidal barrier with a durable lower part
    Patent number: 8061377
    Abstract: An insecticidal barrier (1) having an upper net part (2) with a mesh size preventing insects, for example mosquitoes, to transverse the barrier, the upper net part (2) having a first content of insecticide. In addition, the insecticidal barrier (1) has a lower part (3) with an insecticidal fabric, tarpaulin, foil, woven or knitted fabrics or non-woven, or net with a net material having a higher tear strength than the net of the upper part (2) in order to make the lower part (3) of the net more durable.
