Patent DE-3206617-A1 (DE)
Title: Device for recovering heat from the microbial decomposition of organic substances
Inventor: PROPFE HERBERT TH DR
IPC: C12M1/02
Filed: 1982-02-24
Abstract: A device for recovering heat produced during the microbial decomposition of organic substances in a fermentation reactor has a fermentation reactor. The fermentation reactor is a completely transportable container (1), which is cylindrical and rotatable. By this means, the transportable container can be rotated as a whole during operation and the energy outlay can be considerably reduced. Water-conducting, double-walled, cylindrical heat exchanges (7, 8) standing in direct contact with the material to be fermented can be arranged concentrically at certain distances within the container. This achieves an intimate contact of the fermenting material with the heat exchanger surface. <IMAGE>

Title: System for recovering heat from waste water and for reuse as toilet flushing water
Inventor: MESCHENMOSER ALFONS
IPC: F28D21/00
Filed: 1982-06-23
Abstract: This domestic system for recovering waste heat from waste water as auxiliary heating - and simultaneously recovering the waste water itself for use as toilet flushing water, has no connection to the water mains. The system works without pressure: it has overflow (23) and ventilation (28). The system is mostly used in the bath. The enclosed drawing shows that waste water, e.g. from the washing machine (16) or also bath water from the bath tub (20) or the shower tub (15), is mostly collected in the bath tub (20). From there, this waste water is conveyed upwards into the collection vessels (17) by inserting a funnel (12) with hose (11) into the waste water and employing the suction pump (10). The waste water is filtered in the tub, before being sucked up. After the water has been pumped up into the vessels (17), which are mostly produced from plastic, the latter release the waste heat to the room. The waste water passes as flushing water from the vessel to the toilet via a plastic line. This system without detours permits the household to make savings in costs for fresh water and waste water, and increases heat in the bath or nearby. <IMAGE>
Patent DE-3224028-A1 (DE)
Title: Fibre-like structure made of poultry feathers and process for this purpose
IPC: D01B9/00
Filed: 1982-06-28
Abstract: Fibre-like structure of natural origin for producing spun yarns and fibre webs being particularly lightweight and having excellent heat storage properties. To this end, the poultry feather, preferably chicken feather, parts are used, which, after removing the quill and other unsuitable feather parts, have a minimum length of 8 mm (for spun yarns) and 4 mm (for fibre webs) and an average diameter of less than 25/1000 mm and have a specific direction. In the fibre assembly, these fibrous structures become intermeshed and interlocked with the fibrous structures lying in the opposite direction. This increases their mutual adhesion and the friction resistance upon exposure to tensile and/or torsional stress. The process given for producing such fibrous structures preferably consists in separating of the feather parts which are unsuitable for textile purposes by a pulsating water jet which impinges from different directions, it being possible for this process to be combined with washing of the feather parts.

Title: Process for the purification of exhaust air containing biologically degradable impurities
Inventor: SCHIPPERT EGBERT DIPL CHEM DR
IPC: B01D53/84
Filed: 1982-07-22
Abstract: In a process for the purification of exhaust air containing biologically degradable, in particular poorly water-soluble impurities, the exhaust air is conducted through a scrubber, the impurities are absorbed by a scrubbing liquid containing activated sludge and are biologically degraded by the microorganisms of the activated sludge in an activated sludge tank. In order to increase the absorption efficiency and to obtain a buffer capacity to trap shock loads, the impurities are additionally absorbed by pulverised activated charcoals contained in the activated sludge scrubbing liquid and these absorbed impurities are degraded by the microorganisms of the activated sludge on the activated charcoal. <IMAGE>
Patent DE-3227726-A1 (DE)
Title: Process for the production of valve metal sintered bodies for electrolytic capacitors
Inventor: KASPER EBERHARD DIPL CHEM DR
IPC: H01G9/052
Filed: 1982-07-24
Abstract: The invention relates to the production of valve metal sintered bodies of high specific charge and reduced use of valve metal. The aim is to propose a process for the production of porous sintered bodies of high specific surface area and reduced weight of tantalum used, by using metal spheres plated with valve metal, avoiding the prior disadvantages. A metal powder melting below 800 DEG C, with a higher coefficient of cubical expansion than the valve metal, is plated with a valve metal layer at most 0.5  mu m thick, the plated powder is mechanically pre-shaped, and the metal core is completely or partially melted out under vacuum or inert gas at an elevated temperature, with the formation of hollow spheres of valve metal. The invention is used for low voltage electrolytic capacitors, and possibly also as a contact metal for chemical conversion processes.

Patent DE-3233016-A1 (DE)
Title: Substrate and use of the substrate as a nutrient medium for plants
Inventor: KRUPKA BERND ING GRAD
IPC: C05F11/04
Filed: 1982-09-06
Abstract: There is an increasing demand for making surfaces, for example roof surfaces, vegetation-sustaining so as to utilise the ecological advantages mentioned, thus creating a better environment. The known objects which sustain vegetation are to be considered disadvantageous and of limited applicability only because of their costs, the necessity of artificial irrigation and because of the substantial weight of the layers used. The invention provides a substrate (mixture) as a nutrient medium for plants, which allows roofs to sustain vegetation on a large scale in a self-sustaining manner, while keeping the layer thickness down. Besides lava, sand and ground expanded clays, the substrate contains, as further substances, calcarious gravel and non-frostproof basalt. The plants used are lime-loving plants, xerophytes, mesophytes, which, together with the substrate, form an inseparable biological unit.

Patent DE-3301553-A1 (DE)
Title: Roof gutter
Inventor: MENGE WILHELM
IPC: E04D13/076
Filed: 1983-01-19
Abstract: A covering for roof gutters is indicated which is self-cleaning as a result of the shaping of the sloping screen support which comprises angle plates arranged at a distance from one another. One leg of the angle plate is parallel to flow and the other leg is transverse to the flow direction of the mixture and is designed so as to be inwardly inclined over the horizontal. Alternatively, the teaching according to the invention can also be effected when tongue-like incisions are introduced in the sloping support, which incisions are designed so as to be inwardly inclined to a small extent over the horizontal. In this arrangement, the tips of the tongues are directed approximately counter to the flow direction of the mixture.

Title: Bucket wheel mounting with centrally flanged gearbox
Inventor: KERSTEN PETER DIPL ING
IPC: E02F3/24
Filed: 1983-03-07
Abstract: The invention relates to the mounting of bucket wheels on wheel booms, in particular on large open-cast mining machines. The aim is to reduce the overall width by saving mounting points in order to minimise the mass and the clearance angle on the gearbox side. It is therefore the object to arrange the mounting points of the bucket wheel shaft and of the gearbox in such a way that the wheel boom tip has a minimum width and the clearance angle on the gearbox side is at most equal to that of the wheel track width. The object is achieved by arranging on the gearbox side only one support bearing (3) in the gearbox and by a fixed arrangement of the gearbox housing (4) in the wheel boom tip (2) and by fixing the bucket wheel body (6) on the bucket wheel shaft (5) at two support points (7) or by mounting it via a support bearing (1) arranged in the bucket wheel body (6) on a bucket wheel axle (8) fixed on the belt side in the wheel boom tip (2). <IMAGE>
Patent DE-3308141-A1 (DE)
Title: Method for detecting icing on energy roofs and air-type heat exchangers of heat pumps
Inventor: LANG MARTIN
IPC: F24J2/40
Filed: 1983-03-08
Abstract: A method is proposed for detecting ice on energy roofs and in air-type heat exchangers of heat pumps, which uses the variation in the dielectric coefficient of a capacitor to detect the ice thickness building up. This capacitor is either connected in a very effective cold-conducting fashion to the air-type heat exchanger of a heat pump or to the energy roof, or is formed directly by the gills of the air-type heat exchanger. The varying dielectric coefficient varies the capacitance of the capacitor in the event of ice formation, and is detected using measurement technology with the aid of a frequency generator, rectifier and a switching stage.

Abstract: Torsional vibration damper (10) for motor-vehicle clutches, in which an outer twisting part (11) and an inner twisting part (12) can be twisted relative to one another on a common axis (13) of rotation. The inner twisting part (12) is assigned damper chambers (14), which are filled with a hydraulic damping fluid. The damper chambers (14) are divided by elastic rolling-contact elements (17) into two subchambers (38). The rolling-contact elements (17) roll on outer rolling curves (15) and inner rolling curves (16) and alter the volumes of the subchambers (38). The subchambers (38) are connected to one another via restricted communicating passages. The end regions (20, 21) of the inner rolling curve (16) and the end regions (18, 19) of the outer rolling curve (15) are provided with flexible stops (24 and 25 respectively) which, upon contact with the rolling-contact elements (17), have the effect of a progressive rise in the pushing or pulling torques up to the maximum pulling or pushing angles. By means of these measures, hard shocks on the following drive trains can be avoided. <IMAGE>
