    摘要: A method and a device for determining the flow rate of magnetic or ferromagnetic particles in a suspension that flows through control chambers are provided. The magnetic flux F1 is measured as a function of time t using a measuring coil that surrounds a first control chamber, the magnetic flux representing a measurement, at a particular time, of the quantity of magnetic particles contained in the suspension. In a second control chamber, at a predetermined distance d from the first control chamber, the magnetic flux F2 is measured as a function of time t using a second measuring coil that surrounds the second control chamber and the measurements F1 (t) and F2 (t) are compared to produce a temporal distance Δt which is used together with the predetermined distance d to calculate the flow rate. The method and device can be used, for example, in an ore mining installation.

    摘要: The present invention relates to a strip for preparing security elements for electronic protection of goods including a carrier strip with adhesive labels detachably stuck on, or of interconnected tags to be fixed to goods which are to be labeled or protected. Only a certain number of labels or tags have electromagnetically active or activatable security elements. The strip demonstrates a substantially equal level of detection in different surveillance systems. To this end, the security elements consist of at least two types of security elements which are detectable in different surveillance systems.

    摘要: An arrangement for modifying the local intensity of x-ray radiation includes an x-ray filter with a plurality of absorption chambers, which may be filled by a ferrofluid. The absorption chambers are stacked in the x-ray beam direction. The x-ray filter includes a plurality of storage containers in which the ferrofluid may be stored. Each of the absorption chambers is connected to a respective one of the storage containers. The absorption of the x-ray radiation is achieved as a result of individual absorption chambers being filled with the ferrofluid. By filling a different number of absorption chambers, the local intensity of the x-ray radiation may be modified easily, precisely and quickly.

    摘要: The present invention is directed to a method of manufacturing security elements for electronic article surveillance, the security elements being made of at least two layers, and to a security element manufactured according to the method The method comprises the steps of applying a first layer of a cellulose material in a still moist state to a second layer of a cellulose material, with soft magnetic elements which emit a characteristic signal in the interrogating field of an article surveillance system being added to one of the two layers; and subsequently die stamping or cutting out the desired shape of the security elements from the two layers in the dry state. The method provides a low cost manufacturing means for reliably operating security elements.

    摘要: A system for the supply of forge-proof information about an article. The system has a first element characterized by an information content (I1) and a second element characterized by an information content (I2). Both elements are connected to the article. The two elements are linked to a logic connective where the information contents (I1) and (I2) are compared. One of the information contents relates to a statement as to whether the article is disposable or returnable.
