  • Method and a device for forming a droplet or droplets onto a fibre
    Patent number: 11364664
    Abstract: A method for forming at least a first primary droplet onto a primary fiber includes arranging part of the primary fiber into a reserve of liquid or viscous polymer based material so the primary fiber extends through and on both sides of the reserve. The primary fiber and/or the reserve move relative to each other so a first part of the primary fiber moves out from the reserve with a first primary velocity, forming a first primary layer of the liquid or viscous polymer based material onto the first part of the primary fiber. The first primary layer of the liquid or viscous polymer based material is allowed to form a first primary droplet onto the primary fiber holding the primary fiber relative to the reserve or moving the primary fiber and/or the reserve relative to each other with a first secondary velocity less than the first primary velocity.

  • Process for hydrogenating unsaturated plant-based compounds and regeneration of a used catalyst
    Patent number: 6147235
    Abstract: The invention relates to a process for catalytic hydrogenation of non-hormonal unsaturated plant steroids and unsaturated plant-based fatty acids and triglycerides thereof using a metal catalyst bound to a polymer support containing grafted groups. The invention also relates to regeneration of a used catalyst.
