Inventor: HAAG WERNER OTTO
IPC: C07C2/66
Filed: 1980-11-10
Abstract: A process for the co-production of 2-alkanones having at least five carbon atoms and phenol or a substituted phenol. In the first step, benzene or a substituted benzene is alkylated with an alkyl moiety of at least five carbon atoms to selectively produce the 2-arylalkane isomer. Subsequent oxidation to the hydroperoxide followed by its acid cleavage yields the desired products. The alkylation step is carried out in the presence of a selective crystalline zeolite having pore openings with a major dimension of six to seven Angstroms.

Abstract: To control the pressure difference in a hydraulic motor, it is known to use a single servo-valve with which both the pressure in the feed line to the hydraulic motor and the pressure in the return line are controlled. This has the disadvantage that the clamping pressure in the hydraulic motor (27) is high. To reduce the clamping pressure, there are according to the invention two control valves (28, 29) with which the pressures in the feeder and return line can be controlled independently of one another. <IMAGE>

Abstract: The method is for preparation of a mixture of stereoisomers of a-cyano-3-phenoxybenzyl-2-(4-chlorophenyl)isovalerate or the derivative having 4-fluoro on the phenoxy nucleus. The compounds each have an asymmetric carbon atom in the alcohol and acid moieties. 
     The starting material is a mixture of one of these esters which contains 35 to 65% of an enantiomer pair of isomers of respectively S-configuration and R-configuration on both moieties, the balance being a mixture of the other (S-R and R-S) pair. This material is dissolved in a solvent, such as an alkanol or an aliphatic or alicyclic hydrocarbon; usually seed crystals comprising the desired isomer pair (S-R and R-S) are added and crystallization thereof takes place of this pair. The crystals are removed, e.g. by filtration; residual liquid contains the desired S-S and R-R enantiomer pair which can be recovered by evaporation in vacuo. 
     The product has high insecticidal and/or acaricidal efficacy.

Abstract: A process wherein a colour print, in particular a silk screen print, is applied to a cold base glass, preferably a cylindrical glass parison, and, after reheating to from 500 to 580 DEG C, is covered by a second glass layer as a glass shell, the decorated hollowware subsequently being blown, optionally in a further mould. A variant of the process comprises producing discontinous chain-like air bubbles in the intermediate layer by removing only some of a gas-forming component in the silk screen print before the overcoating. Furthermore, one of the two glass layers may be a coloured glass. A number of attractive glass decorations can thus be achieved.

Abstract: A capacity control device (10) for a variable displacement compressor (1) in a refrigerating or air conditioning system is disclosed. The capacity control device (10) controls the operation of a variable displacement device (9) in the compressor (1) to change the capacity of the compressor (1) from a large to small volume and vice versa. This capacity control device (10) is responsive to the required refrigerating capacity of the compressor (1) operating at small volume. The required small volume rotation frequency is compared to the actual rotation frequency to determine whether the compressor (1) should operate at large or small volume. If the required small volume rotation frequency is smaller than the actual rotation frequency, the capacity control device (10) actuates the variable displacement device (9) to enable the compressor (1) to operate at small volume. If the required small volume rotation frequency is larger than the actual rotation frequency, the compressor (1) is operated at large volume or capacity.

Abstract: The invention relates to aluminium-chloride compositions for water-purifying, sludge-dewatering and plant-dewatering purposes, comprising a clear, stable aqueous solution of aluminium chloride containing polynuclear complexes of the kind Alm(OH)n(3m-n)+ where m and n are positive integers. The composition is characterized in that it contains ions of alkali metal and/or alkaline earth metal in an amount which stoichiometrically substantially corresponds to the OH-content of the solution, and in that the total aluminium content is between about 0.3 and about 2 mole per liter. At least 40% of the total aluminium content of the solution may be present in the form of said polynuclear complexes. The invention also relates to a method for producing the composition, in which method a carbonate or hydrocarbonate, alkali metal or alkaline earth metal and an aluminium chloride are brought into aqueous solution. The amount of aluminium chloride is selected so as to obtain in the solution a total aluminium content of between about 0.3 and about 2 mole per liter, and the amount of carbonate or hydrocarbonate is selected so that, in relation to the amount of aluminium chloride, a given highest ratio is obtained between the number of moles of OH and the total number of moles of aluminium in the resultant solution at the desired given aluminium content of the solution.

Abstract: Dans une machine dynamoélectrique possédant un champ rotatif et un noyau de stator stationnaire (11), des conducteurs électriques (19) sont contenus dans des fentes radiales s'étendant axialement (15) qui font partie de la construction du noyau du stator. Les conducteurs électriques pour les barres de stator sont soumis à des forces électromagnétiques et à des effets de fluctuation thermique qui, à la longue, provoquent le déserrage des barres de stator dans leurs fentes. Ce problème est résolu par un système amélioré de calage qui applique une force aussi bien immédiate que résiduelle sur les barres de stator (19a et 19b) et qui maintient les barres en place même après que certains tassements ont eu lieu. Le système amélioré de calage comprend une pluralité de cales de pression espacées axialement (27), chaque paire de cales de pression étant maintenue en place au moyen d'une cale de bordage (31) et d'une cale à queue d'arronde (37).
