Abstract: The present invention relates to a method for treating a surface in order to improve the removability of microorganisms from the surface, comprising the steps: —applying a treatment solution onto the surface, wherein the treatment solution comprises an aqueous solution of a collagen hydrolysate; and—allowing the surface to dry. The present invention further relates to the use of collagen hydrolysate for treating a surface in order to improve the removability of microorganisms from the surface.

Abstract: A receiving container for a detector which operates in an ultrahigh vacuum or in a protective gas atmosphere that consists of high-purity gas. The receiving container has a receiving portion which forms at least a portion of the receiving space for the detector, and a cover for hermetically sealing the receiving space. A first sealing surface is arranged at the receiving portion and a second sealing surface matching the first sealing surface is arranged at the cover. Between the sealing surfaces a gasket is arranged. A securing device presses the cover against the receiving portion to provide a defined contact pressure of the gasket.

Abstract: A diazo pigment dye having the formula ##STR1## in which R.sub.1 represents a hydrogen, chlorine or bromine atom or a nitro group, andR.sub.2 and R.sub.3 a hydrogen or chlorine atom or a methyl or methoxy group.A new coupling component for preparing the pigment is also disclosed. The dye possesses good tinctorial and advantageous environmental properties. Methods for preparing the dye are disclosed.

Abstract: Mixed pigments containing an organic pigment component and an inorganic pigment component imparting improved gloss and other desirable properties to organic coatings containing the same in relatively large amounts are prepared by synthesizing the organic component in the presence of the inorganic component in a liquid medium inert to the inorganic component, such as nickel titanium yellow or chromium titanium yellow.
