|20120283495||METHOD AND A DEVICE FOR GENERATING A CARBURIZING GAS MIXTURE - A method to generate a ternary carburizing gas mixture, using a reaction of selective hydrogenation of acetylene in a stream of hydrocarbons to the form of ethylene, comprising the following steps: heating of the inside of the reactor with an inert gas to an operating temperature for a period of 20 minutes at a temperature of 300° K, passing a mixture of hydrogen and acetylene by the regiospecific catalyst, and moving out the reaction products on the outside after passing the mixture through the regiospecific catalyst, but generation is effected in a continuous mode in the operating temperature range of the regiospecific catalyst between 293° K and 398° K, preferably at a temperature of 350° K.||11-08-2012|
|20110243728||Blower designed for fitting particularly in a chamber furnace - The blower designed particularly for fitting in a chamber furnace has the hub of the rotor wheel in the shape of a solid of revolution with its slant height described by n degree polynomial and its Dp||10-06-2011|
|20100272422||RETORT FURNACE FOR HEAT AND/OR THERMOCHEMICAL TREATMENT - A retort furnace designed for heat and heat and chemical treatment in protective gas atmosphere, process gas atmosphere or in vacuum, equipped with a retort with a lid, made of steel or heat-resisting or creep-resisting alloys, separating the process atmosphere from the ambient atmosphere, with heating elements and thermal insulation outside the retort and with a cooling system. The radiation screens, in the form of at least two metal boards, are installed at supports located at the lid inside the retort; the heating elements are located behind the radiation screens, on the retort side and are separated with the metal screen. A few radiation sealing rings are placed in the extreme area of the brackets. The radiation screens and sealing rings, as well as the circumferential sealing rings permanently fixed in the casing of retort make up the system of reducing heat losses through radiation at the wall of the retort.||10-28-2010|
|20080277029||Method and measurement system for the control of an active charge surface in the low pressure carburizing process - A method and measurement system for the control of an active charge surface in a low pressure carburizing process can avoid formation of by-products and achieve regular carburized layers. This can be achieved through sampling of outlet gas at a specified time and comparison with experimentally set model characteristics.||11-13-2008|
