Abstract: A method for determining the rheological properties of a sample substance by the use of a rheometer, in which at least one element having magnetoelastic characteristics is received in said sample substance. The element is set into mechanical oscillation by the influence of a magnetic field and its oscillation characteristics are determined by the effect exerted by the oscillation of the element on an outer magnetic field which, in turn, provides information regarding the rheological properties of the sample substance. The device comprises a receptacle for the sample substance and the element. An exciting coil array is provided for exciting the element, thus causing it to oscillate mechanically; and a sensing coil array is provided to register the effect of the element on an existing magnetic field image during oscillation of the element. A calculation unit is operatively engaged with the sensing coil array for determining the oscillation characteristics of the element and therefrom deriving the rheological properties of the sample substance.

Abstract: The invention relates to a method and a device for remote sensing of objects, said method including the steps of marking said objects with at least one label (10) comprising at least one electrical resonant circuit (14) having an induction means (11) and a capacitor means (12), exciting said resonant circuit (14) to resonance at a resonant frequency, and detecting said resonant frequency of said resonant circuit (14) by the electromagnetic energy transmitted from said resonant circuit (14). An element (13) of a magnetic material having a varying permeability is coupled inductively to said induction element (11). The resonant frequency of said resonant circuit (14) is affected by the permeability of said element (13) of magnetic material, and said element (13) of magnetic material is exposed to an external and spatially heterogenous magnetic bias field through which the permeability of said element (13) of magnetic material is controlled. The invention relates also to methods for coding labels and for noise suppression of signals received from said labels.

Abstract: A printer, which is especially adapted for printing a bar code on label paper has a housing having a front panel with some operation buttons and a winding drawer having a protruding label table. The printer prints a bar code and alphanumeric numerals on a label which is fed to the label table for then being applied to goods. The printer also can be connected to an external computer or the like for obtaining the information to be printed on the label. The printer also has an internal processor and a memory for maintaining certain necessary information. The winding drawer has a winding roller and a deflection roller on a pivotable operation lever. The deflection roller deflects ground paper of the label paper over a dispenser edge in a first position of the operation lever, so that a label formerly on the ground paper is delivered straight ahead while the ground paper is deflected downwards to the winding roller operation. The lever and deflection roller also may be pivoted forwards to a second position, whereupon the ground paper including the labels can be delivered straight forwards as a long strip of labels maintained on the ground paper. By pulling out the winding drawer to an extended position and pivoting the operation lever and deflection roller to the second position, the labels on the ground paper also may be wound on the winding roller for later use. The printer also has one or several printing heads which are pivotable about 90.degree. for cleaning printing points thereof. The printing heads are easily exchangeable by loosening only two screws.
