Patent DE-4028397-C1 (DE)
IPC: C02F11/12
Filed: 1990-09-07
Granted: 1992-02-27
Abstract: The problem in the use of sewage sludge for landfilling is to achieve sufficient solidity of the sewage sludge after incorporation. It is known for this purpose to add binders to the dewatered sewage sludge. However, this leads to an unwanted increase in volume. It is furthermore known to mix dewatered and dry sewage sludge, and to structure and subsequently to compost the mixture. However, this leads to great technical elaboration of the plant. The invention is intended to make possible treatment of the sewage sludge for landfilling with little technical elaboration of the plant. At the same time the volume is intended to be low and the solidity after incorporation sufficiently high. Sewage sludge which can be used for landfilling is produced by mixing dried and dewatered sewage sludge, the mixture being produced from a coarse fraction of sewage sludge dried with granulation and from dewatered sewage sludge with a DM content of 65 to 88%.

Title: Paper machine
Inventor: WANKE WILHELM
IPC: D21F1/00
Filed: 1994-09-22
Granted: 1997-02-27
Abstract: A double wire on a paper machine is constructed as a gap-former. The suspension is sprayed into the gap between two wires or similar water extn. material. There is at least one cross-rail beneath the bottom wire for water extn.. The profile of the cross-rail begins with a convex shape and having two radii in the direction of the run of paper. The second radius is larger than the first. Pref. the two wires have water extn. from the suspension and a paper formation in direction with thickness which is compressed in the gap. At the beginning of the area of the cross-rail which has a smaller radius, the water is extracted below, in front of it, without forming ridges, or a wave which shows as a fault in the paper. The second area has a radius which is larger. There is water extn. above the top wire, which provides adequate fluid to enable the bottom wire to glide over the cross-rail. The system may be formed into a series of water extn. points on the machine. It is necessary for the return rollers for the wires to be set to give the required angle in approaching the gap former.

Abstract: Изобретение относится к поршневым двигателям внутреннего сгорания. Целью изобретения является снижение удельного расхода топлива и повышение мощности. Способ повышения топливно-мощностной эффективности двигателя внутреннего сгорания заключается в том, что цикл сгорания топлива смещается по углу поворота кривошипа, при этом объем камеры сгорания до завершения горения топлива остается постоянным за счет остановки поршня на этот период в верхней мертвой точке без остановки вращения кривошипа. Эта десинхронизация их взаимодействия происходит в течение поворота кривошипа на угол 30 - 40° от верхней мертвой точки. Достигшее максимума давления газов при этом сочетается с наибольшим значением тангенциальной составляющей усилия, действующего от шатуна на кривошип. Двигатель внутреннего сгорания, реализующий способ, содержит шатун, состоящий из двух частей, соединенных телескопической вставкой с пружинами, удержавающими части шатуна в сжатом состоянии. На верхней части шатуна по бокам симметрично установлены на осях ролики. В плоскости их расположения на щеках кривошипа установлены кулачки, входящие в контакт с роликами при положении поршня в верхней мертвой точке до момента завершения рабочего такта. 2 с. и 1 з.п. ф-лы, 4 ил.

Temperature of dust-gas mixture in pulverized-coal duct 4 is measured by transducer 7 and its signal arrives at algebraic unit. Temperature in pulverized-coal duct will be maintained equal to average value for all pulverized-coal ducts. If temperature in pulverized-coal duct proves to be lower than the average temperature for all pulverized-coal ducts, regulator 8 will send signal for closing valve 6 to reduce transportation ail supply. Should temperature in pulverized-coal duct be above the average, regulator 8 increases air amount with the help of valve 6. EFFECT: higher efficiency. 1 dwg

Granted: 1994-08-15
Abstract: FIELD: powder metallurgy. SUBSTANCE: article has its cavity filled with powder before being placed at a spaced relation to the heat source and rotated on being simultaneously heated to the sintering temperature. The sintering of the article is accompanied by its transfer relative to the heat source. As the article is heated to the sintering point the heat source to article clearance is kept constant with the article additionally receding from the heat source along its radius to the following rule (experimental or estimated): l = U(T) = f(T). U(T) = shifting of the article surface points caused by thermal expansion vs. heating time with the relationship being defined by experimental or calculational means with allowance made for the temperature gradient along the depth of the article. T = outer surface temperature defined by experimental or calculational means with regard to nonlinearity of the assigned heat conductivity. The temperature is peculiar to the time at which the sintering point is achieved on the contact interposed between the inner surface of the article and the coating applied. At a period when the article is kept at the sintering temperature effected is additional radial relative drifting the article and the heat source apart which action at any time is determined by the time dependence of power with the latter being in its turn determined by the size of the clearance between the article and the heat source. EFFECT: lower energy consumption, higher quality of coating. 1 tbl, 6 dwg
