Polyurethane dispersions based on reaction products from (A) bismethylolated urethanes having at least 2 urethane groups and (B) polyhydroxyl compounds which contain groups which are capable of ion formation, these groups being present in neutralized form, and a process for the preparation thereof. The use of the dispersions for the surface-coating of metal, plastics, glass, leather and paper.

A grating bar for floor mats. The bar has two legs that form the walls of a U-shaped profiled strip. Cleaning elements are disposed between these walls, and the latter are provided with openings for holding elements. Provided on the outer surfaces of the walls, between the openings and the free ends of the legs, are projections that can be united to form an element that extends over the entire len...

Flat glass is disclosed, bearing a tin oxide coating layer which is at least 200 nm in thickness. In order to promote a uniform visual appearance across the coated area, the expected grain area of a representative sample of the tin oxide coating crystals measured in units of 10-4 mu m2 is numerically equal to a value of at least 0.4 times the layer thickness measured in nanometers.

Suitable as "ballast portion" for fusion proteins is a part of the amino-acid sequence of interleukin-2 (IL-2) which comprises considerably less than 100 amino acids. It is advantageous to start from a synthetic IL-2 gene which is divided by unique cleavage sites into six segments of which up to three can be linked in any desired sequence by the building block principle. Specific constructions all...

The present invention relates to a snow chain for vehicle wheels, whereby the snow chain comprises two chain members adapted to extend along the peripheral tread surface of the vehicle wheel when the snow chain is mounted on said wheel. The snow chain comprises tie bars connecting the chain members to each other and adapted to extend transversely to the tread surface when the snow chain is mounted...

In a nuclear reactor fuel assembly, a relatively flexible mounting member for mounting a large coolant conducting tube to the lower tie plate whereby excessive side forces on the fuel rod spacers are avoided in the event of lateral displacement of the fuel assembly such as during a seismic event.
