Patent EP-0569830-A1 (EP)
Inventor: OESTERGAARD HANS
IPC: G01N1/20
Filed: 1993-05-05
Abstract: A system for sampling milk produces an identical sample size when a valve (4) is used, which comprises a piston (22) provided with an annular groove (23), which during the reciprocating of the piston alternately is brought in connection with a drain pipe (5,19) and a discharge opening (26) in the valve (4). 
     During the entire sampling a bottle is secured, which at the insertion into the valve (4) is sealed with a membrane. This sealing may be broken at the first stroke of the piston (22) when the outermost end (24) of the piston penetrates into the neck of the bottle. After the final stroke a ball (28) may be positioned opposite the piston and be pressed into the neck of the bottle, which consequently is deformed. When the bottle is removed from the valve (4) a subsequent inadmissible manipulation with the sample cannot occur. 
     The sample is determined by the capacity contained in the annular groove (23), and the number of reciprocals of the piston (22). These are distributed evenly over the entire draining of milk from a farm tank, which content is coded in a control unit.

Abstract: A method for producing lower alkali glass wherein fluxing activity provided by alkali oxides is replaced by fluxing activity provided by water in the glassmaking process. Water is effectively and efficiently provided to the glass by the establishment of a high water vapor concentration in the glassmelting zone atmosphere which is produced by a defined heat-generating oxygen-based combustion reducing nitrogen and boosting the water vapor concentration, and maintained in the glass by passing molten glass through successive refining and forehearth zones having atmospheres with high water vapor concentrations.

The silver halide crystals to be used in the said material show a fog level, a toe contrast and an overall contrast that is, like the image quality, substantially uneffected by the processing conditions. The coating amount of silver halide crystals in the emulsion layer can be reduced to such an amount that an archivability of from 10 to 20 years can be assured in normal storage conditions. The X-ray material is suitable for rapid processing, without loss in sensitivity, within processing cycles of 45 or 38 seconds, wherein hardener-free processing solutions can be used.

Abstract: Waste sulphuric acid is dried in a drier 10 and the resulting dried acid is decomposed in a reactor 12 by contact with a volume of liquid sulphur through which oxygen is passed. The decomposition products of the sulphuric acid initially comprise water vapour and sulphur trioxide. The sulphur trioxide is reduced to sulphur dioxide by sulphur vapour. The resulting mixture comprising sulphur, sulphur dioxide and water vapour has sulphur condensed therefrom. The sulphur dioxide content of the gas mixture is reacted with hydrogen sulphide in a Claus plant 14 to form a sulphur product. Alternatively the mixture containing sulphur vapour can be reacted with a hydrocarbon such as methane to form hydrogen sulphide and carbon disulphide which in turn are reacted with the sulphur dioxide to form the sulphur product.

Läßt die Reaktion auf eine Verstimmung der Vorderradbremsen oder auf einen Defekt schließen, wird die Begrenzung des Druckanstiegs in den Radbremsen der Hinterräder (HR, HL), die eine Auswirkung der Regelung der Bremskraftverteilung ist, aufgehoben. Die Hinterräder leisten folglich in dieser Situation einen erhöhten Beitrag zur Abbremsung.
