Abstract: Binders for coating agents, which are polycondensation products from equimolar amounts of aromatic dicarboxylic acids and diols which contain from 5 to 50% molar of the total diol amount of a neopentylglycol ester of hydroxypivalic acid and which have a melting point range of from 60.degree. to 150.degree. and a K value of from 20 to 45. The products are particularly suitable for coating strip metal.

Abstract: Production of formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst and a tertiary or secondary amine. The formaldehyde which can be prepared by the invention is a disinfectant, tanning agent, reducing agent and valuable starting material for the production of synthetic resins, adhesives and plastics.

Abstract: A continuous process for the manufacture of cyclohexanol from cyclohexene in two stages involving the addition of sulfuric acid and hydration, the addition of sulfuric acid being carried out in the presence of iron(II) sulfate. In a special embodiment, the addition of sulfuric acid is carried out in the first stage at atmospheric pressure and at the boiling temperature of cyclohexene.

Abstract: The present invention relates to thermostable coating, impregnating and bonding agents. They are suspensions of finely divided water-insoluble or at most only slightly water-swellable thermostable organic binders or mixtures based on these binders in aqueous solutions of high molecular weight organic substances. They are used particularly for coating wire, for the production of thermostable coatings and for the production of laminates.

Abstract: Azo dyes containing sulfonic or carboxylic acid groups and having a substituted 2-hydroxypyridone-(6) as coupling component. The dyes are particularly valuable for dyeing natural or synthetic polyamides.

Abstract: Manufacture of low molecular weight block copolymers of vinyl or diene monomers and alkylene oxides. In a first stage, the vinyl or diene monomers are polymerized as chain stopper, and in a second stage, one or two blocks A are added thereto by the addition of further alkylene oxide. The resulting block copolymers may be used as prepolymers for the manufacture of polyurethanes, as dispersing agents for dyes, as antistatic agents, emulsifiers, surfactants or as paper and textile finishing agents.

Abstract: Method of producing .gamma.-butyrolactams by reacting .gamma.-butyrolactones with ammonia in the presence or absence of water at elevated temperatures and pressures. The reaction is carried out continuously at temperatures ranging from 180.degree. to 340.degree.C whilst maintaining pressures which are at least 10 percent higher than the pressure equal to the sum of the partial pressures of the reactants at the temperature used. .gamma.-Butyrolactams are valuable intermediates, for example in the manufacture of polymers, pharmaceuticals and solvents.

Abstract: Cardiac stimulants and vasopressor agents for peroral and parenteral administration containing 6-alkoxy-pyridazinium compounds as active ingredients.

Abstract: Water-soluble synthetic tanning agents composed of formaldehyde condensation products of non-sulfonated aromatic hydroxy compounds or the sulfomethylation products thereof with aromatic sulfonic acids or with the formaldehyde condensation products of said sulfonic acids.

Abstract: Method of controlling fungi with substituted benzoic acid derivatives, in particular substituted benzanilides.

Abstract: New and valuable dithiophosphoric esters which have a strong insecticidal and acaricidal action, and a process for controlling pests with these compounds.

Abstract: A process for the production of high molecular weight .alpha., .beta.-unsaturated aldehydes by alkylation of the .gamma.-carbon atom of a lower molecular weight .alpha., .beta.-unsaturated aldehyde with a substituted allyl alcohol which has a chain branching in the 3-position carbon atom or a phenyl radical in the 3-position or of a corresponding allyl alcohol carboxylic ester at elevated temperature in the liquid phase.The products are valuable intermediates for the production of natural substances and odorants.

Abstract: Production of formaldehyde by vaporization of a mixture of methanol and water in the presence of a mixture of alkanols and dialkylethers, and then by a catalytic, oxidizing dehydrogenation of methanol. The formaldehyde obtainable according to the process of the invention is useful as a disinfectant, a tanning material, a reducing agent or as a valuable initial material for the production of synthetic resins, adhesives and plastics.

Abstract: Herbicidal compositions embodying mixtures of S-halobenzyl-N,N-dialkylthiolcarbamates and 3-lower alkyl-2,1,3-benzothiadiazinone-(4)-2,2-dioxides and salts thereof in weight ratios of 1:5 to 5:1.

Abstract: New .alpha.-hydroxy-.beta.-aminocarboxylic acids which are agents for masking metal ions and auxiliaries for the paper and textile industries. Other outlets are in the textile industry in dyeing and bleaching, in metal refining, in the foodstuffs industry (bottle washing) and in the field of catalysts (fuel cells, accumulators).

Abstract: New and valuable N-substituted sulfonylglycolic acid anilides and a process for controlling the growth of unwanted plants with these compounds.

Abstract: New and valuable substituted succinic acid oximidophosphoric esters having a strong insecticidal action, pesticides containing these compounds as active ingredients, a process for controlling pests with these compounds, and a process for their production.

Abstract: Guide elements for magnetic tapes wound or to be wound in the form of packs on flangeless spools, the guide elements being movable in the plane of rotation of the packs. At least part of the guide elements is located between the pack and the outermost winding and thus constantly guides the tape as it is wound or unwound, resulting in optimal tape guidance and consequently in a stable and accurate winding on the spool.

Abstract: The invention relates to a magnetic tape cassette and a tape recorder for use with such a cassette. More specifically, the invention relates to the provision of movable means within the cassette, which means -- in a first position -- hold the magnetic tape taut and prevent movement of the reels in the cassette and -- in a second position -- release the magnetic tape and the reels, which may then be rotated by the tape recorder, the tape being guided only by means attached to the recorder. Magnetic head positioning means provided on the recorder are adapted to adjust the position of magnetic heads, which are rigidly mounted on a head plate which is movable relatively to the tape, to the desired position for recording and reproduction.
