Abstract: The surface character of flexible materials is examined by means of interference fields which are formed by reflection of light beams from a reflecting reference surface and from the adjoining surface to be examined, and subsequent super-position of the partial beams thereby formed. The interference field which corresponds to the surface profile standing out from the reference surface is utilized to determine the length and height of the surface profile, with the aid of the interference band spacings and the wavelength of the incident light.

Abstract: In order to determine the homogeneity of a magnetic dispersion, part of the dispersion is conducted through a measuring cell prior to its application to a base, the size, number and type of those regions of the magnetic dispersion which interfere with the homogeneity being determined with the aid of magnetic measurements. The measuring cell contains a magnetic head, a magnetic dispersion is made to flow in a stream of constant cross section past the air gap of the magnetic head, and a magnetic field at least partially penetrating the magnetic dispersion is produced. From the characteristics of the amplified output voltage of the magnetic head the various parameters of the inhomogeneities in the magnetic dispersion can then be ascertained.

Abstract: A laminated magnetogram carrier, consisting of a substrate with >=2 magnetic layers contg. an acicular magnetic material in an organic binder system, has a toper layer contg. a magnetic pigment with a high static signal-to-noise voltage ratio (S/N) pref. over 61.0 dB whilst the S/N is lower pref. below 61.0 dB for the pigment in the lower layer the coercivity of the materials differing by a max. of +10%. Flexible magnetogram carriers satisfying high requirements w.r.t. static noise are obtd. without the exclusive use of pigments with the required S/N value.
