  • Patent number: 6537588
    Abstract: The invention generally relates to the use of natural anti-secretory proteins (NASP) for the preparation of NASP-enriched functional food products or pharmaceutical products for the treatment and prophylaxis of disease-like conditions caused by extreme body fluid discharge. In particular, the invention relates to the use of NASP-enriched egg yolk as source of NASP.

  • Publication number: 20020099016
    Abstract: A new recombinant protein called Antisecretory Factor (rAF) and homologues and peptide fragments thereof are described. The protein and the homologues and fragments thereof are useful for normalising pathological fluid transport and/or inflammatory reactions in animals including humans. Antibodies against AF or homologues or fragments thereof are described. Nucleic acids coding for the protein or for homologues or fragments thereof are also described as well as vectors and hosts comprising the nucleic acids. The rAF and homologues and fragments thereof could be used for immunodetection, as feed additive for growing animals and as antidiarrheal and drugs against diseases involving edema, dehydration and/or inflammation.

  • Patent number: 6075294
    Abstract: In a locking system, used for instance on a vehicle, a switch or sensor initiates the interrogation of a data storage medium via a control unit to check for access authorization. If access authorization is given, the control unit releases the locks of the locking system automatically. To improve user convenience regarding the system release, at least one capacitance sensor in at least one door grip is provided. At least one first electrode of the sensor is situated in the inner shell of the door grip and a second electrode is placed in the door area opposite the grip. By applying antipole voltage to both electrodes, an electrical field is generated between the two electrodes. When a hand, which acts as a dielectric, approaches the grip, a change in the cumulative dielectric state between the two electrodes occurs. Such a change is recognized by the capacitance sensor and transformed into an electric pulse which initiates in the electrical control unit interrogation of the data storage medium.

  • Patent number: 5620436
    Abstract: A method and apparatus for providing more precise aiming by an eye tracking system, including a registration, or aiming, laser, that provides for precise location of where the next laser ablation shot will impinge upon the eye. The method and apparatus further includes an aiming assistance fixture that provides a fixed frame of reference for locating the origin of the eye.

  • Patent number: 5296243
    Abstract: The subject of the invention is a process to correct and optimise the feed-composition on basis of testing the levels of so called FIL-lectines in the blood. This correction is exerted by adding certain sugars and amino acids to the feed. Hereby the FIL-level may be adjusted in order to optimize the growth.

  • Patent number: 5201548
    Abstract: A method and apparatus of faithfully reproducing a multicolor image having three-dimensional texture utilizes a photomechanically reproduced copy of the image on a carrier substrate which is suitable for embossing and a matrix providing the three-dimensional textured characteristics of the image is used to electrolytically form a female embossing die corresponding to the shape of the matrix whereupon a complemental male embossing die is made by means of which the carrier may be squeezed between the male and female dies to produce a highly accurate copy exhibiting the coloration and fine detail of the image texture. Various end uses are contemplated.

  • Patent number: 5116562
    Abstract: A new process for producing a reproduction of a painting or the like wherein the reproduction has a relief surface which imitates the relief surface of the painting or the like. Heat and pressure are applied simultaneously to an assembly consisting of a mold of the painting, a colored sheet for coloring the reproduction and a substrate to retain the reproduction. Subsequent to this step, shock cooling is applied. The reproduction thus produced does not suffer from the rebound effect of the prior art and good color integrity is maintained.
