Title: Pipeline, in particular for effluent
Inventor: BRAEUTIGAM JUERGEN DIPL ING
IPC: F16L9/18
Filed: 1983-11-23
Abstract: Blockages of effluent and sewer pipelines due to deposits of settling solids due to greatly varying throughputs, can be counteracted according to known proposals by fitting in the interior of the pipe a flexible diaphragm which is constantly loaded on its upper side by a water cushion. The diaphragm, resting directly on the surface of the effluent, is deflected relatively far upwards and downwards with the changing level of the said diaphragm, and this together with the considerable length of pipelines fitted out in this way makes high demands on the permanent, sealing fastening of the diaphragm edges on the inside wall of the pipe. According to the invention, the side edges of the diaphragm are formed in the region in which they are fixed either by an inflatable hollow space running through in the manner of a tube, or according to a variant, by a subsequently produced thickened portion. The novel diaphragm design ensures the desired pressure-tight fixing even over a lengthy period of time, and it also permits trouble-free production as well as features which make it easier to wind up, pack and transport the diaphragms, which are comparable in their dimensions to, for instance, conveyor belts.

Title: Regulating device for the hydraulic power-lifting system for a semi-mounted plough
Inventor: RESCHKE JUERGEN DIPL ING
IPC: A01B3/46
Filed: 1984-04-26
Abstract: In tractors with a semi-mounted plough which is operated by a control of traction resistance, the wheels tend to dig in and the work quality is uneven. It is proposed to connect to the lifting line between the regulating directional valve and power-lifting cylinder of a conventional power-lifting system a bypass line, into which is inserted a flow-regulating valve which discharges from the lifting line a constant leakage flow which is independent of the pressure in the lifting line. This generates a continuous lowering of the power-lifting system and therefore a more rapid and more uniform response of the regulating directional valve.

Title: Process and apparatus for purifying exhaust air laden with pollutants
Inventor: MEUSER WOLFGANG
IPC: B01D53/34
Filed: 1984-09-14
Abstract: A process is to be created for purifying exhaust air laden with pollutants, in particular industrial exhaust air, which operates with low energy consumption and without the use of hazardous chemical substances within a large temperature range, without a previous cooling of the exhaust air or the hot exhaust gases being necessary. For this purpose, the invention provides that activated charcoal of a high degree of purity is pulverised, is mixed with water to form an activated charcoal-water suspension and is atomised within the flowing exhaust air. An adsorption of the pollutants, in particular odour substances, takes place in this case to the water mist droplets in which the pulverised activated charcoal is situated and to which pollutant portions are adsorbed. By suitable catalysts, the activated charcoal-water suspension can easily be regenerated again, so that a continuous process is possible without waste water problems.

Abstract: Summarising, the invention provides a process for producing comminutable coal, with reduction in the metal content represented in the coal by Si, Al, Ca, Na, K and Mg, the following being provided: contacting of a coal/water mixture in a weight ratio of approximately 4:1 to 1:6 in the presence of CO2 at pressures of approximately 100-1400 psi and at a minimum temperature of approximately 15 DEG C for a period of one or more hours to produce a treated coal/water mixture. In the process, the treated coal/water mixture has Ca and Mg values which are reduced by up to 78% as compared with the starting mixture, and the advantageous CO2 concentration is in the range of approximately 3-30 g/l. Below 5 g/l of CO2, only small effects are observed, and above 30 g/l no special advantages are obtained. The coal/water ratios in the range from 1:2 to 2:1 are particularly advantageous, and such ratios are compatible with applications of coal/water suspensions.

Title: Method for the physical and/or chemical influencing and/or treatment of stacked or piled material by means of flowing media
IPC: C21D1/767
Filed: 1984-11-12
Abstract: A method is described for the physical and/or chemical influencing and/or treatment of stacked or piled material by means of flowing media, such as liquids, air, gas or gas mixtures in a treatment chamber, in which the flowing medium is circulated in two treatment flows, which are directed towards one another and meet one another, in such a manner that the region in which the media meet one another moves to and fro in the transverse direction of the chamber. This known method is to be applied to processes in which the treatment or influencing takes place with heating and cooling of the material with a holding time of any length between heating and cooling or holding periods of any length between heating and cooling, it being possible to control rates and duration of the heating and holding periods as required and as accurately as possible without great heat losses having to be accepted. This is achieved by heat being supplied or extracted in a controlled manner outside the treatment chamber with circulated treatment flows.
