Patent RU-95107401-A (RU)
Inventor: VERTKIN M A
IPC: F01K21/04
Filed: 1995-05-06
Abstract: FIELD: heat-power engineering; steam-gas plants with disposal of gases of gas turbines into boiler for combined generation of thermal and electric power. SUBSTANCE: steam-gas plant has gas turbine 1, steam turbine 2 with high-pressure unit 3 and low-pressure unit 4, boiler 5 with furnace chamber 6 provided with burners 7, drum 8, blower 9, gas duct 10 connecting exhaust line of gas turbine 1 with furnace chamber 6 for shutting off its gas inlet by means of gastight damper 11. Boiler also contains units 12 and 13 connected in parallel with high-pressure unit 3 and low-pressure unit 4 by feed water line, common economizer 14 whose feed water inlet is hydraulically connected with feed water outlet of high-pressure unit 3 and unit 13, steam superheater 15 and evaporator which is partially made in the form of screens of furnace 6 and partially in the form of screens of boiler walls and other evaporating surfaces located in way of flow of flue gases after burners 7 of furnace 6. According to specific features of invention, boiler is provided with additional convective heat exchange surface located in way of flow of exhaust gases of gas turbine between burners 6 and exhaust line of gas turbine 1. Air inlet of gas duct 10 is in communication with blower 9 for shutting it off with other gastight damper. Air inlet is located in way of flow of exhaust gases of gas turbine before above-mentioned additional surface. Water inlet is located in exhaust gas line on side of burners 6 of furnace 7 and is hydraulically connected with circulating pump of drum 8; water (steam) outlet is located on side of gas and air inlets of gas line 10 and is hydraulically connected with drum 8 through adjusting valve and with water inlet of unit 13 through adjusting valve 22; water inlet of common economizer 14 is hydraulically connected with steam line of steam super-heater 15 through adjusting valve 23. EFFECT: enhanced reliability.

Inventor: AKSEL KENIG
IPC: B01D53/00
Filed: 1994-06-28
Abstract: FIELD: gas treating. SUBSTANCE: between melt charging location and exhaust air fitting in exhaust air hood, surface insertions 15 are placed directed labyrinthwise into the stream and serving as crystallization surfaces for vaporous part of product, which is further removed in solid state thereby preventing it from getting into exhaust air stream. Method is chiefly intended for use at installations for granulating chemical products, in particular, sulfur. EFFECT: improved environmental condition.
Patent RU-95110058-A (RU)
Inventor: MUKHAMMED MAMOUN
IPC: B22F1/00
Filed: 1995-06-08
Abstract: FIELD: powder metallurgy. SUBSTANCE: method includes preparation of powders containing WC and cobalt and/or nickel. Special powder and powder of basic salt of cobalt and/or nickel are mixed with water. Suspension is mixed to originate the reaction in temperature range from room temperature to solution boiling point. In this case, precipitate falls out which is filtered, dried and reduced to melt powder. EFFECT: higher efficiency.
Patent RU-95111589-A (RU)
Inventor: UMANETS V I
IPC: B22D11/00
Filed: 1995-07-05
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: metal is fed into casting mold, narrow walls are displaced, and ingot is maintained and guided under the mold by means of rolls and is also drawn from mold. With locally decreasing diameter of roll barrel by 0.005-0.1 its diameter, narrow walls are displaced (both simultaneously or one of the two) in the region of ingot angles to a summary value equal to 0.001-0.8 roll barrel length. EFFECT: increased firmness of rolls maintaining and guiding ingot.

Inventor: AL GIN V B
IPC: B60K17/06
Filed: 1996-02-01
Abstract: FIELD: transport engineering; transmissions of automobiles and medium and heavy trailer-trains. SUBSTANCE: multistage gearbox has housing, input shaft, first and second planetary trains internal central wheels of which are connected with brakes, external central wheels are in meshing with each other and with first countershaft coupled through clutch with input shaft. Carrier of first planetary train is connected with internal central wheel of second planetary train and with second countershaft coupled through clutch with input shaft. Gearbox has also mechanism connecting input shaft with internal central wheel of first planetary train. Gearbox has additional countershaft, brake, clutch and planetary train similar to first two trains. Additional brake is connected with internal central wheel of additional planetary train. Additional clutch couples external central wheel and carrier of additional planetary train, additional countershaft connects carrier of second planetary train and external central wheel of additional planetary train; carrier of additional planetary train is connected with output shaft. Ratio of number of teeth of central wheels of additional planetary train is selected to meet definite relationship. Planetary mechanism coupling input shaft with internal central wheel of first planetary train has one or two brakes. This mechanism can be made multiflow with fixed shafts, and it is provided with clutch. EFFECT: enlarged gear ratio range of gearbox, provision of small difference in gear ratios in operation. 6 cl, 3 dwg
