  • Patent number: 7984635
    Abstract: The present invention relates, in general, to sheet material forming technology and the forming of structures there from. The invention relates to incremental forming of sheet material (1) with localised heating (5) and more particularly to a system and method for incrementally forming a sheet blank (1) that is at the same time heated by a dynamically moving heating source (5). This dynamic and localised heating locally changes the mechanical properties of the sheet material (1), thus facilitating the forming process.

  • Patent number: 7930771
    Abstract: A protective helmet is described comprising: an outer layer (1); an inner layer (5) for contact with a head of a wearer; and an intermediate layer (3, 4) comprising an anisotropic cellular material comprising cells having cell walls, the anisotropic cellular material having a relatively low resistance against deformation resulting from tangential forces on the helmet. The anisotropic material can be a foam or honeycomb material. The foam is preferably a closed cell foam. The helmet allows tangential impacts to the helmet which cause less rotational acceleration or deceleration of the head of the wearer compared to helmets using isotropic foams while still absorbing a significant amount of rotational energy.

  • Publication number: 20110086099
    Abstract: The invention describes a new class of crystalline silica material having two levels of porosity and structural order. At the first level, building units are nanoslabs of uniform size having zeolite framework. At the second structural level, nanoslabs are assembled, e.g. linked through their corners, edges or faces following patterns imposed by interaction with cationic surfactant or triblock copolymer molecules. After evacuation of these molecules, microporosity is obtained inside the nanoslabs, and a precise mesoporosity between the nanoslabs depending on the tiling pattern of the zeolite nanoslabs, as evidenced by X-ray diffraction. These materials are useful for the fixation of biologically active species, such as poorly soluble drugs.

  • Patent number: 7823499
    Abstract: Present invention involves a seal means suitable to replace the classic seals. For instance the seal means of present invention can be a liquid seal ring (7) to replace the classic rubber seal rings. Such is liquid O-ring can be adapted to resists the actuation pressure relying on surface tension forces. Such liquid O-rings can also be linked in series, hereby increasing the maximum seal pressure. In a preferred embodiment the seal means of present invention comprises two major components, a surface tension seal (7) and a pressure divider (4). The pressure divider will comprise a system that generates a pressure drop. Such pressure divider can be located before the surface tension seal and perform the first pressure drop. The combination of these two systems has the advantage that the surface tension seal is able to reduce the leakage to zero or essentially zero and that the pressure divider is able to perform a large pressure drop.

  • Patent number: 7754215
    Abstract: The present invention clearly demonstrates that vWF-collagen interaction, via the A3 domain of vWF, plays an important role in acute platelet-dependent arterial thrombus formation and that blocking the A3 domain in a vWF-collagen interaction can induce complete abolition of thrombus formation in the injured and stenosed baboon femoral arteries. Accordingly, an antibody or an antigen recognizing fragment thereof binding specifically to the A3 domain of vWF or an epitope thereof can be used for the prevention of acute arterial thrombotic syndromes or to manufacture medicines to for the prevention of acute arterial thrombotic syndromes.
