  • Patent number: 7201880
    Abstract: The invention relates to a sample dispenser, for the application of liquid samples on to a sample absorbing area, with a sample dispenser body (1) having at its end a sample pick-up surface (5) bounded by a continuous edge (6), wherein the sample pick-up surface (5) is provided with a recess (7) such that, when the sample pick-up surface (5) is dipped into a sample reservoir, a droplet of liquid sample of predetermined size adheres to the sample pick-up surface (5) and by placing of the sample pick-up surface (5) on the sample absorbing area is completely dispensed, and wherein the recess (7) is in the form of a flat recess (7), that is to say, it has a depth which is less than its width. The sample dispenser according to the invention is of very simple design. In using it, the desired sample amount to be transferred is determined by the flat recess of the sample pick-up surface and can be reproduced very precisely.

  • Patent number: 6383271
    Abstract: An anti-corrosive coating composition suitable for providing corrosion protection for a sheet metal substrate includes from 20 to 97 wt. % of a filler dispersed in a polymeric base or matrix material. The filler includes at least one filler material having a hollow cellular structure, of which the hollow cells are loaded with organic and/or inorganic inhibitors and/or antioxidants. The hollow cellular structure material may be diatomaceous earth, zeolite, or carbon. The inhibitors and/or antioxidants may be selected from carbonic acids, amines, ketones, aldehydes, heterocyclic compounds, phosphates, benzoates, silicates, vanadates, tungstates, zirconates, borates, molybdates, benzaldehyde, vitamin C, vitamin E, or the like. A long term durable corrosion protection is achieved because the inhibitors and/or antioxidants are released from the hollow cells of the filler material in a dosed time-release manner over the operating lifetime of the anti-corrosive coating.

  • Patent number: 6368718
    Abstract: An anti-corrosive coating for structural steel components contains 3 to 80 wt. % of a binder including polymeric material, and 20 to 97 wt. % of a filler including semiconductive elements or compounds. A process for welding a steel component coated with such an anti-corrosive coating involves temporarily energizing the semiconductive material of the coating into its conductive state and then carrying out the welding process, e.g. electric spot welding, while the semiconductive material is in the conductive state. Thereby, the coating does not hamper the electric welding operation. The step of energizing the semiconductive material is achieved by temporarily applying an external energy such as localized heating or incident light radiation having a photon energy corresponding to an energy band gap of the semiconductive material.
