Abstract: The invention relates to a device for determining the dew point temperature of a measurement gas, having a light guide, a condensation surface located on the light guide and whose reflectivity is dependent on the condensation of the measurement gas, a light source for emitting light through the light guide onto the condensation surface, a light sensor for determining the light intensity reflected back into the light guide by the condensation surface and means for adjusting the temperature of the condensation surface, which has a semihydrophobic construction.

Abstract: An apparatus relates to an approach warning system for detecting when a person approaches an object which has a metal outer structure at least in regions.

Abstract: The invention relates to a method for transferring a liquid having a gas inclusion at least at times and for determining the amount of liquid transferred, in which the liquid is conveyed through a line, a degree of filling measurement is carried out in the line, a flow measurement is carried out in the line and a calculation, in particular multiplication, is performed on the result of the degree of filling measurement and the result of the flow measurement, whereby a conveyed amount value is obtained. It is thereby provided that the conveyed amount value, which is obtained by performing a calculation on the result of the degree of filling measurement and the result of the flow measurement, is corrected with a value which takes into consideration a dissolution of the gas inclusion in the liquid, whereby a corrected conveyed amount value is obtained, and the corrected conveyed amount value is used as a measure for the liquid amount transferred.

Abstract: The invention relates to a method for determining an amount during the transfer of a liquid, wherein the liquid is introduced at a supply opening into a measurement line and is removed from the measurement line at an outlet opening, and an amount of liquid flowing through the measurement line is determined by means of a flow measuring unit assigned to the measurement line. According to the invention, liquid present in the measurement line is discontinuously fed to a degassing arrangement. The invention further relates to a device for determining an amount during the transfer of a liquid.

Abstract: A process and apparatus are disclosed for taking a representative milk sample during the delivery of a milk charge from one container to another. With respect to the errors encountered in operating peristaltic pumps with different speeds of revolution, the invention predetermines a corrected pumping characteristic as a function of an acceptance characteristic and correspondingly controls the taking of samples.

Abstract: The invention concerns a reading head with a tapered reading opening and/or a tapered reading stylus for reading bar-type, especially passive magnetic information on a data carrier. A high resolution in reading this information with a high output signal is obtained by tapering the reading opening in direction of the end face of the reading head. The reading head is located in a casing pot and has at least one field plate sensor, on which side remote from the face a permanent magnet is placed with a magnetic shunt to the casing pot.
