Abstract: A nozzle, for use with a power air blower or the like, to direct a high velocity sheet of air onto a surface, such as that of a motor vehicle's body, in order to displace water or other loose matter from the surface. The nozzle includes a longitudinal air outlet gap which produces a high velocity sheet of air to be directed by the operator onto a surface, in order to displace water or other loose matter therefrom.

Abstract: A benzylpiperidine compound of formula I ##STR1## in which R.sup.1 is H, Hal or nitro,R.sup.2 is a benzyl group, which is unsubstituted or substituted by Hal on the aromatic portion, in the 2-, 3- or 4-position of the piperidine ring, with the proviso that R.sup.2 is not in the 4-position if X is --CO--, Y and Z are --CH.sub.2 and R.sup.1 is H,R.sup.3 is H or A,X is --O--, --S--, --NH--, --CO-- or --SO.sub.2 --,Y is --CH.sub.2 --, --NH--, --O--, --S--, --NH-- or alternatively --CO-- if X is --CO-- and Z is --NH-- or --NA--,Z is --CH.sub.2 --, --C(A).sub.2-, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --CO--, --NH--, --NA--, --O--, --S-- or a bond,wherein X--Y or Y--Z is not --O--, --S--S--, --NH--O--, --O--NH--, --NH--NH--, --O--S-- or --S--O,A is alkyl having 1-6 C atoms,B is O or both H and OH, i.e.

Abstract: The invention relates to NAD(P)H-dependent nitrate reductase from yeasts, to a process for the preparation thereof and to the use thereof in a reagent for determining nitrate. The nitrate reductase is characterized by a molecular weight of about 350 000 D and can be obtained by yeast cells which have been cultivated in a completely synthetic nutrient medium with nitrate as the sole nitrogen source and which contain nitrate reductase being disrupted in phosphate buffer, the crude extract being chromatographed on an anion exchanger, the fractions containing nitrate reductase being mixed with protein, concentrated by ultrafiltration and dried by fluidized bed granulation. The reagent for determining nitrate contains, besides the nitrate reductase prepared in this way, also NAD(P)H and a color reagent for determining nitrite.

Abstract: A high pressure fluid valve including a valve body (16), a valving member (18), a first handle (20), a yoke (15), and a second handle (128). The yoke (15) is sized and shaped to fit over the valve body (16) and has a throughhole (116) sized, shaped, and positioned to be brought into register with an end of a passageway (26) in the valve body (16). The second handle (128) is manually manipulatable from the exterior of the valve body (16), is operably connected to the yoke (15) such that movement of the second handle (128) in one direction causes the throughhole (116) in the yoke (15) to be brought into register with the end of the passageway (26) in the valve body (16), and is sufficiently spaced from the first handle (20) to permit easy manual manipulation of both the first handle (20) and the second handle (128).

Abstract: The invention relates to a process for the preparation of N-protected dialkyl (2S,3S)-3-ethylaspartates or their salts from unpurified (2S,3S)-3-ethylaspartic acid obtainable by enzymatic amination of ethylfumaric acid.

Abstract: The invention relates to a novel process for the preparation of carebastine and similar materials from ebastine or terfenadine by oxidization using microorganisms. Carebastine and similar materials are used for the treatment of allergic disorders and as antihistamines.

Abstract: In a process for the reduction of ketones, the keto compounds are enantioselectively reduced to give secondary alcohols by means of microorganisms. Keto compounds of the formulaR.sup.3 NH--CHR.sup.1 --CO--CH.sub.2 --COOR.sup.2in which R.sup.1, R.sup.2 and R.sup.3 have the meanings defined herein are used as starting compounds.
