A coating system and a method for its manufacture are provided. An electrically conductive base coat and a porous overcoat lying over the base coat are arranged on a ceramic substrate. At least one additional deposited layer is arranged on the base coat in such a way that the additional layer is formed in the pores of the porous overcoat adjacent to the base coat. The additional layer is deposited either by currentless or electrolytic deposition. For electrolytic deposition of the additional lay...

The invention relates to a substantially dry fine product comprising fructose, glucose, a sugar alcohol or mixture containing them, prepared by grinding the fructose, glucose, sugar alcohol or mixture containing them substantially autogenously in a counterjet mill and classifying the ground product to a mean particle size of 5-25 .mu.m. The invention also relates to a process for preparing such a fine product and to the use of the product to prepare chocolate or icing, a fondant, hard candy, che...

Mesoporous silica has a specific surface area of the mesopores of at least 500 m.sup.2 /g and a volume of the mesopores of at least 1.0 ml/g and is prepared by converting a silica precursor in a water-containing reaction medium, the reaction medium containing a polymer dispersion.

A process for the preparation of polymaleic acid by polymerizing maleic anhydride in an aromatic hydrocarbon at from 60.degree. to 200.degree. C., using from 1 to 20% by weight, based on maleic anhydride, of peroxyesters derived from saturated or ethylenically unsaturated carboxylic acids, as the polymerization initiators and hydrolyzing the polymer, the polymaleic acid thus obtained and the use of the polymaleic acid as an agent for reducing scale formation and hard water deposits in systems th...

A textile auxiliary for improving the fastness of materials dyed or printed with a dyestuff is a copolymer of a diallylammonium monomer, a vinyl amide monomer and a (meth)acrylic ester monomer.

7a-Nitromethyl-2,3,5,6,7,7a-hexahydro-1H-pyrrolizine of the formula ##STR1## and salts thereof, as well as processes for the preparation of the compound and 7a-aminomethyl-2,3,5,6,7,7a-hexahydro-1H-pyrrolizine and salts thereof.

A porous polymeric material has cell sizes within the range 100 to 0.5 .mu.m and total pore volume with respect to the overall volume of the material in the range 75 to 98% and includes cross-linked polycondensation polymeric material. The material can be made from a high internal phase emulsion in which the cross-linked polycondensation polymer is formed in the continuous phase. The materials are preferably open interconnected cellular structures. They can be made of a wide range of polycondens...

Electrically conductive polythiophene and its derivatives are prepared by polymerizing compounds of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen, R.sup.3, --OR.sup.3 or --SR.sup.3 ; and R.sup.3 is aryl of 6 to 12 carbons or aliphatic of 1 to 12 carbons; comprising reacting the compound of formula I in the presence of an initiator, the initiator comprising a 2-substituted thiophene nucleus which has a lower oxidation potential than the compound of formula I and whi...

A workbench with its devices, which includes a work table which is formed with a plurality of o-shaped or straight bars each equally spaced apart, and adjusting clamps, which can be installed in between any two of the bar materials on the work table. If the clamps are loosened a bit, the adjusting clamps will be permitted to move in position along the bars. The use of one piece or pieces of adjusting clamps will be permitted to clamp and treat workpieces of any shape and size, wherein two slowin...

An ultra-violet flashlight comprising a housing containing an ultra-violet light source, a power source, an on/off switch and a gravity switch, whereby the ultra-violet light source is activated by turning on the on/off switch and directing the flashlight in a downward position relative to the ultra-violet light source and a method for instantly sterilizing objects with which a person comes in contact comprising passing over said objects ultra-violet radiation from said flashlight.
