Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.

Abstract: Aryl-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar in the formula represents a substituted or unsubstituted aryl or heterocyclic radical; R represents hydrogen or a C.sub.1 -C.sub.12 alkyl or cycloalkyl (saturated or unsaturated) or Ar as above; Im represents a 1-H-imidazol-1-yl group (unsubstituted or substituted); and Y represents a saturated or unsaturated C.sub.1 -C.sub.12 alkyl or a group --Z--Ar in which Ar has the above meaning and --Z-- is a saturated or unsaturated C.sub.1 -C.sub.12 alkylene wherein each of the alkyl and the alkylene may have a carbon chain once or twice interrupted by or, in the case of the alkylene, terminated on its Ar-end by oxy, thio, sulfinyl or sulfonyl bridges, always with the proviso that at least one of Ar and Y is a heterocyclic radical. These compounds are wide-spectrum fungicides and bactericides, and the preferred compounds among them are hydrophilic.

Abstract: Therapeutic xanthine oxidase inhibitor composition containing as an active ingredient 3-dimethylamino-7-methyl-1,2-(n-propylmalonyl)-1,2-dihydro-1,2,4-benzotria zine dihydrate of the formula ##STR1## Uratic diathesis in warm-blooded animals is therapeutically treated by administering the aforementioned xanthine oxidase inhibitor to such animals, e.g., human, either orally or by means of an injection, thereby inhibiting their xanthine oxidase activity.

Abstract: Aryl-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar in the formula represents a substituted or unsubstituted aryl or heterocyclic radical; R represents hydrogen or a C.sub.1 -C.sub.12 alkyl or cycloalkyl (saturated or unsaturated) or Ar as above; Im represents a 1-H-imidazol-1-yl group (unsubstituted or substituted); and Y represents a saturated or unsaturated, acyclic or cyclic C.sub.1 -C.sub.12 alkyl, or aryl or aralkyl, or an alkyl or alkylene residue directly bound to the ether oxygen and having a chain once or twice interrupted by --O--, --S--, --SO-- or --SO.sub.2 -- bridges. These compounds are effective wide spectrum fungicides and bactericides.

Abstract: .alpha.-Aryl-.beta.-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar represents a substituted or unsubstituted aryl group, R an alkyl, aryl or aralkyl group, X an oxygen atom, a sulfur atom, a sulfinyl or a sulfonyl group and R1 a lower alkyl group or a nitro group. These compounds are effective wide spectrum fungicides and bactericides. To prepare these vinyl ethers, a corresponding 1-arylacylimidazole is o-alkylated in presence of NaH with a corresponding .alpha.-halogen ether, .alpha.-halogen thioether, .alpha.-halogen sulfinyl compound or a corresponding .alpha.-halogen sulfonyl compound.

Abstract: Novel hydrazines are disclosed in which one of the nitrogen atoms forms a ring member of the five membered ring of a [4.3.0] heterobicyclic compound which may be substituted elsewhere in the ring system. Characteristic ring systems described include indole and benztriazole ring systems. The compounds possess anti-depressant properties as well as anti-microbial, in particular fungistatic and bacteriostatic, properties.

Abstract: This invention relates to novel thioethers as well as to the addition salts thereof with inorganic or organic acids. The novel compounds and their addition salts have valuable anti-mycotic and fungicidal properties. Further the invention relates to a process for preparing the novel compounds and their addition salts, and to anti-mycotic and fungicidal compositions containing the novel thioethers, or addition salts thereof, as the active constituent.

Abstract: Imidazolyl oxime ethers (I) are disclosed which contain an aromatic or heteroaromatic grouping linked to the carbon atom of the oxime ether, the oxime being etherified by a variety of groups; aliphatic, aromatic, heteroaromatic, cycloaliphatic and aliphatic substituted by aromatic, heteroaromatic or cycloaliphatic groups. The compounds are obtained from the corresponding ketones by reaction with O-substituted hydroxylamines or by reaction of metal oximates with halides of the required etherifying group. The said products (I) possess antimycotic and bactericidal activity.
