Abstract: Disclosed is a layer for use in a domestic appliance, based on a sol-gel precursor. This layer can be obtained by screen-printing and comprises an organosilane compound. The layer is obtained from a concentrated pre-polymerized sol-gel precursor. The layer can be used as an insulating layer or as a conductive layer in a heating element. Furthermore, the layer can be used for decorative purposes.

Abstract: The invention relates to a process for preparing arylsulphonyl isocyanates of the general formula (I) ##STR1## and addition derivatives thereof--where in the formula the meaning of the substituents are as follows:Ar represents optionally substituted aryl, naphthyl- or thienyl group, andHX is a chemical bond or XZR.sub.1 stands for a group where Z is oxygen or sulphur,R.sub.1 is saturated or unsaturated alkyl, benzyl, cyclohexyl or substituted phenyl group orX is an NR.sub.2 R.sub.3 groupwherein R.sub.2 R.sub.3 is hydrogen, alkyl, unsubstituted alkyl, aryl, substituted aryl, aroyl or acyl group, and the essence of the process is that an N-halogen sulphonamidate is carbonylated in the presence of a carbonylating catalyst, in the presence or absence of alcohol, (thio) alcohol or amine reactants and the carbonylated compound obtained is reacted subsequently with the reactants.

Abstract: The invention relates to a process for preparing sulphonyl-ureas of the general formula (I) ##STR1## wherein Ar.sub.1 represents a phenyl, naphthyl or thienyl group, the derivatives thereof substituted by C.sub.1-4 alkyl, C.sub.1-4 haloalkyl, (halo)alkoxycarbonyl, (halo)alkyloxy, nitro, cyano groups as well as by halogen atoms,Ar.sub.2 represents a phenyl, pyridyl, pirimidinyl or triazinyl group and the derivatives thereof substituted by C.sub.1-4 (halo)alkyl, C.sub.1-4 (halo)alkyloxy, amino, O-acyl, O-arylsulphonyl, O-(substituted carbamoyl) groups as well as by halogen atoms.

Abstract: The invention relates to a new polyacrylamide adhesive suitable for the fixing of fine-particle sorbent layers based on organic and/or inorganic compounds, used in overpressured one- and multilayer chromatographic procedures.The said adhesive is prepared by polymerizing the aqueous solutions of acrylamide and N,N'-methylene-bis-acrylamide in the presence of a catalyst pair at from 21.degree. to 30.degree. C., pulpifying the precipitate thus obtained and repeating the precipitation and the pulpification more times.

Abstract: Apparatus for the prediction of performance parameters of a proposed machine, in particular, an agricultural machine, includes a keyboard for entry of data in accordance with a set of input parameters useful in the calculation of performance parameters, a display for displaying performance parameters, a memory for storage of data inputted by the keyboard, and a data processor interconnecting the memory and the numerical board for performing mathematical calculations to output values of the performance parameters in response to the inputting of data at the keyboard. Included within the data processor is an analyzer for selecting input parameters specific to a mathematical correlation, a microprocessor for calculating values of intermediary parameters from the inputted data based on patterns of such data, and a synthesizer employing values of selected input parameters and the intermediary parameters to provide mathematical correlation for attaining values of the performance parameters.

Abstract: The invention relates to a process for preparing alumina being suitable for layer chromatography.The alumina suitable for layer chromatography is prepared in accordance with the invention in such a manner that an aluminium trinydroxyde containing 34 to 37% by weight of bayerite, 3 to 5% by weight of pseudoboehmite and 60 to 62% by weight of amorphous aluminium trihydroxide is heated at 300.degree. C. to 400.degree. C. for 2 to 4 hours.The activated alumina thus produced is snow-white, has a large specific surface and its average grain size is within the range between 8 and 20 .mu.m.The product complies with the requirements of layer chromatographical technique.
