Abstract: An apparatus and a method allows a determination of the degree of hardness of semisolid materials with a higher accuracy and a simultaneously lower sensitivity with respect to electronic and mechanical disruptions. An adjusted force value (FBer) is determined prior or during a downward movement of a force/path sensor (20) and the force difference (?F32??F51) is determined between the adjusted force value (FBer) and respective measured force value (?F32??F51) and a zero time (t41) is determined, wherein the position (21, s41) of the measuring body (5, 8) at the zero time (t41) is used as the exact starting position (21, s41) of the surface of the material to be measured (22).

Abstract: A device and a method for an accelerated oxidation test of fuels or petroleum products, as well as a computer program for controlling such a device, and a corresponding computer readable storage medium, which are applicable, in particular, for the simulation of the aging of fuels or petroleum products. A device for an accelerated oxidation test of fuels or petroleum products is proposed, whereby the device comprises of a pressure vessel (1) to hold specimen (2) of fuels or petroleum products, and the pressure vessel (1) contains at least one device to change the temperature. A corresponding method provides that a specimen (2) of fuel or petroleum product is placed in a pressure vessel (1), the specimen is brought to a predefined temperature above 100° C. by at least one device to change the temperature, which is placed in the pressure vessel (1) and/or in the specimen (2), and the absolute pressure value is monitored so as to determine the oxidation.

Abstract: The present invention relates to a method and an apparatus for determining the degree of hardness of semisolid materials, in particular the present invention relates to a penetrometer for the measurement of the degree of hardness of road surfaces such as asphalt or for the measurement of the degree of hardness of lubricants. It is an object of the present invention to provide an apparatus and a method that allow a determination of the degree of hardness of semisolid materials with a higher accuracy and a simultaneously lower sensitivity with respect to electronic and mechanical disruptions in comparison to the prior art.

Abstract: The invention describes a method and a device for determining the filling level and can be applied, in particular, for the ascertainment of the simmering process of mineral oil products.

Abstract: The invention describes a method and a device for determining a filling level and can be applied to the ascertainment of the simmering process of mineral oil products. The method is characterized that by means of at least two stationary sensors, a first filling level and at least a second filling level are defined and the number of drops required for reaching the first and second filling levels is recorded. By way of a further sensor the number of drops dropped in during the simmering process is counted and, by way of calculation, the partial volume at a specified location and the filling level are determined.
