A method and an apparatus for restoration of industrial furnace refractory masonry with a ceramic facing, includes burning of fuel components of ceramic facing mixture in an oxygen stream to form a torch, melting refractory powders of the mixture by this torch with simultaneous fusing surface layer of masonry area to be restored and facing its damaged places by the melt of refractory powders, the ceramic facing mixture being exposed to a weak pulse magnetic field. A method of preparation of a ceramic facing mixture including exposing the mixture to a weak pulsed magnetic field. The technical result is increasing the efficiency of the method of ceramic facing, by lowering the mixture's viscosity and by increasing its fluidity.

The pseudopolymorph of desloratadine formed with carbon dioxide of the formula (I) has valuable anti-allergic effect and can be used as pharmaceutical active ingredient. The present invention also relates to the preparation of desloratadine of high purity. The present invention also relates to the use of the pseudopolymorph of desloratadine of the formula (I) for the preparation of salts of desloratadine of the formula (VI) (wherein X stands for an anion and n is 1 or 2).

The invention relates to the pneumatic circuit of a device for ceramic surfacing a damaged refractory masonry (lining) of furnaces without cooling said furnaces. A chamber pump (1) is connected by means of a switch (20) to a compressed air source and uniformly and controllably supplies a powdery castable refractory mixture contained therein to a refractory tuyere (2) input in order to mix said mixture with oxygen at a specified ration and to supply it to a local repairable area. Said invention makes it possible to ensure the reliable and stable long-term operation of the device under conditions of repetitive on/off switchings of the compressed air supply for transporting the powdery castable refractory mixture. For this purpose, the switch (20) is associated with a pressure relieve filter (18) from the chamber pump cavity and is embodied in the form of a four-port on/off pneumatic distribution valve. The selected number of inputs and outputs of the pneumatic distribution valve automatically ensures a pressure pre-relief from the chamber pump into atmosphere during the switchings, thereby preventing the clogging of the holes by the refractory mixture transported from the chamber pump (1) through an aerator (5) and an aerating air pressure stabiliser (6).

The efficiency of an exothermic autoclave leach process is increased by increasing the retention time of the solids fraction in the feed slurry over that of the liquid fraction. This is achieved by flashing the contents of the first oxidative autoclave compartment to a flash vessel, with the underflow therefrom passing to a thickener and the underflow from the thickener being fed to the autoclave feed tank or any tank upstream of the feed tank. Exothermic heat generated in the first compartment of the autoclave is abstracted in the flashing process. Additionally portions of the overflow from the thickener are returned to the feed tank and fed to the autoclave discharge tank.

The invention relates to tablets and film-coated tablets containing as active ingredient citalopram hydrobromide having a median particle size of less than 40 µm in admixture with microcrystalline cellulose having a median particle size in the range of 90-250 µm and other excipients conventionally applied for the preparation of tablets. The invention also provides a process for the preparation thereof.

The invention solves the issue of the way of sending wishes, greetings and invitations. Wishes, greetings or invitations are sent by means of a properly shaped packet and with a sound and picture bearers attached to it on which there are recorded properly selected situations, texts, songs, melodies, sounds of nature and other sounds characteristic of the type of the mail and corresponding with the kind of wishes, the place from which wishes were sent and the form and aim of invitations. The packet for the realization of the way of sending wishes, greetings and invitations according to the invention consists of an envelope or a card (1) with a drawing or a photograph placed on the front surface (33) of it and with a sound and picture bearer or sound bearer (4) placed between the front layer (3) and back layer (2) of it and with recorded situations, texts, songs, melodies, sounds of nature and other sounds corresponding with a photograph or a drawing placed in the front of the packet.

The invention can be used for fuel assembles in nuclear engineering, in particular for the structure of a rigid framework. The inventive fuel assembly consists of head and rear parts which are connected to each other by guiding channels arranged in cells of spacer grids. Said guiding channels are rigidly connected at least to end spacer grids. The height (h) of the spacer grids and the wall thickness (δ) of the cells thereof are selected in such a way that the quantitative characteristics thereof correspond to a calculatedly-and-experimentally determined condition. Said invention makes it possible to improve assembling rigidity at transversal and longitudinal bending, to increase an angular rigidity of the «a guiding channel-a cell of spacer grid» pairs, to reduce the fuel assembly bending in its own plane between the spacer grids and the free bending of the fuel assembly in non-homogenous neutron and temperature fields by the decreased tendency of a E635 alloy to radiation growth.

The invention is directed to a process for the preparation of [4(S,R)-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalene-1-ylidene]-methyl-amine of the Formula (I) by reacting 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)naphthalene-l-one of the Formula (II) with monomethyl amine which comprises carrying out the reaction in the presence of thionyl chloride in an ether-type solvent. The [4(S,R)-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalene-1-ylidene]-methyl-amine of the Formula I is a valuable pharmaceutical intermediate.

The present invention relates to a new method of preparation of the polymorph form 1 of methyl (S)-(+)-(2-chlorophenyl)-2-(6,7-dihydro-4H-thieno[3,2-c]pyridine-5-yl-acetate hydrogensulfate of the formula (I).

The present invention relates to a new method of preparation of the polymorph form 1 of methyl (S)-(+)-(2-chlorophenyl)-2-(6,7-dihydro-4H-thieno[3,2-c]pyridine-5-yl-acetate hydrogensulfate of the formula (I).
