Patent DE-3626483-A1 (DE)
Title: Chimney renewal insert
Inventor: RAMMO EDGAR DIPL ING
IPC: F28D21/00
Filed: 1986-08-05
Abstract: The chimney insert serves for renewing domestic and industrial chimneys with a flue gas capacity for boilers up to 1000 kW. It is produced in one piece in tubular special steel and is introduced into the chimney to be renewed by means of a building crane. Around the special steel tube is a water cooling jacket with dished ends and a helical water flow pipe is welded in from the bottom to the top inside the jacket. When the chimney renewal insert has been introduced, the water cooling jacket is connected by its first connection nozzle to the heating return line directly before the heating boiler in the partial flow. The water is fed upwards inside the jacket to just below the upper end and emerges in a jet-like manner, and subsequently flows down inside the jacket in order to be removed at the second connection. During this process, the heating water cools the flue gases down to the value of the heating return temperature and simultaneously absorbs this residual energy. Depending on the temperature level of the heating return line, even the utilisation of the latent heat in the flue gas region, e.g. at return temperatures below 45 DEG C is successful.

Title: A rapid test method for the nondestructive determination of the permeability of concrete surfaces
Inventor: SCHOENLIN KLAUS DIPL ING
IPC: G01N33/38
Filed: 1986-08-26
Abstract: The subsurface permeability of a concrete component is determined non destructively by means of a suction cap (1) which rests directly on the concrete surface and is connected to a vacuum pump (3) for evacuating the interior of the suction cap and to a manometer (5). The space enclosed by the suction cap (1) and the surface of the concrete (2) is evacuated. The time-dependent decrease in the vacuum or increase in the air pressure which sets in inside the suction cap after the termination of the evacuation process as a result of closing a flow stopcock (4) between the vacuum pump (3) and the suction cap (1) together with the manometer (5) is evaluated as a measure of the permeability to be determined which can be calibrated empirically. <IMAGE>

Title: Compact pneumatic-stowing station
Inventor: ADAM UDO
IPC: B65G23/44
Filed: 1986-11-22
Abstract: For the pneumatic stowing of faces in underground mining, a compact pneumatic-stowing station is provided which consists of the rubber belt serving as a conveyor unit as well as of the pneumatic-stowing machine, which in each case are in contact with one another but can be displaced independently of one another in the longitudinal direction of the face. In this arrangement, the rubber belt has a discharge head which has a longitudinally variable deflection-roller unit assigned to it and therefore acts in such a way as to be variable in length so that the distance between the pneumatic-stowing machine and the belt drive can be varied in accordance with the conditions. This ensures that the pneumatic-stowing machine travels along in accordance with the respective face advance or pneumatic-stowing advance so that an optimum distance is always guaranteed. The heavy belt drive need only be moved up at certain intervals, and it serves as an abutment for the displacement of the pneumatic-stowing machine. To this end, the pneumatic-stowing machine is equipped with pushing beams and feed cylinders which at the same time can also be used for recovering the belt drive if the pneumatic-stowing machine as such is effectively fixed. With a pneumatic-stowing station of this type, large quantities of pneumatic stowage can be introduced in relatively short time intervals so that the interruption in the winning operation can be kept short. In addition, due to the small distance between pneumatic-stowing machine and face, an advantageous ... Original abstract incomplete. <IMAGE>

Title: Device for preparing a combustible mixture
Inventor: SCHILLING SIEGFRIED W
IPC: F23D11/40
Filed: 1987-01-27
Abstract: The device serves to prepare a combustible mixture from liquid or gaseous fuels and air for burners or integral firing equipment of heat generators. A spacer taking the form of a corrugated ring (10) is located between a fire tube (9) and a guide tube (2). This device consists of a flame retention baffle (1) seated in a guide tube (2) and a fire tube (9), in which the guide tube (2) is positioned coaxially, and movable along the longitudinal axis. The inside diameter of the guide tube (2) in the region of the flame retention baffle (1) is at least 0.4 mm larger than the outside diameter of the flame retention baffle (1), with the annular gap (3) thus created having no interruptions on the circumference. The complete guide tube (1-8) is held in a coaxial position to the fire tube (9) by an elastic spacer (10). This mixing device is very suitable for automatic operation, since the forces needed to shift the flame retention baffle if the fire tube is deformed are small, and the drives necessary to displace the devices are small and cheap. <IMAGE>

Title: Safety roof hook
Inventor: SPRIESTERSBACH DIETER
IPC: E04D13/12
Filed: 1987-04-14
Abstract: Such safety roof hooks 1 are provided on rafters 2 on relatively steeply sloping roofs, on which there are fitted, when providing new roofings and doing repair work, lay-on ladders and roof seats for roof tilers and connecting means for safety equipment. In order that the differences, which often result, during roofing, in the positions of the low-lying water channels of the roofing tiles, from which the safety roof hooks 1 extend, relative to the rafters 2, can be compensated for in a simple manner without having to make any changes, the fastening part 3 is configured as a widened plate with a multiplicity of rows 4 of holes. Consequently, in the case of, for example, a rafter width dimension 5 of 60 mm and a spacing of the outer holes 11 according to dimension 6 of 75 mm, a lateral displacement of the safety roof hook 1 by dimension 7 of 85 mm is possible, with a minimum spacing dimension 8 of the nails 9 from the outer rafter edge 10 of 25 mm. <IMAGE>

Title: Process and apparatus for purifying exhaust air
Inventor: GOSELWITZ HELLMUTH
IPC: B01D47/06
Filed: 1987-05-08
Abstract: The invention relates to a chemisorption process and an apparatus for purifying exhaust air having in particular up to a medium loading of readily soluble pollutants, in which the exhaust air coming from a pipe is conducted through a housing arranged longitudinally upright or horizontally. In this case, the exhaust air is passed through a plurality of scrubbing liquid compartments which collect the scrubbing liquid and the exhaust air, after passing through a demister, is purified and fed into an outflow pipe. The apparatus for carrying out the process has a housing, in the interior of which are arranged nozzle bars, which eject scrubbing liquid co-currently with the exhaust air flowing through the housing. The housing is connected at one end to a pipe feeding exhaust air and at its other end to a pipe conducting away the exhaust air. Flow calming of the exhaust air in combination with influencing the flow velocity, and the variability of the arrangement enable exhaust air purification to be carried out more cost effectively with retention of the respective fan output available, utilising the most diverse space conditions.

Title: Multiple-casing steam turbine
Inventor: MEYLAN PIERRE
IPC: F01D25/26
Filed: 1987-12-17
Abstract: In this multiple-casing steam turbine, the axial thermal expansion, which takes place starting from the bearing housing (5) on the intermediate-pressure section (element) turbine (1), of the portion of the shaft line (assembly) (4) on the low-pressure side is compensated due to the fact that the low-pressure steam feedlines (leads) (15, 16), which are rigidly connected to the intermediate-pressure section turbine (1), are rigidly mounted on the inner housings (11, 12) of the two-casing low-pressure section turbines (2, 3). Because of the equality of temperature, the abovementioned portion of the shaft line (4) and the low-pressure steam feedlines (15, 16) expand to the same extent, with the result that the axial plays between the rims of the fixed (stationary) and moving (rotating, rotor) blades of the low-pressure section turbines (2, 3) are also essentially maintained. The otherwise customary connecting elements between the intermediate-pressure and the low-pressure section turbines are eliminated, in common with the sealing problems at the outer housings bound up therewith. <IMAGE>
