Title: Cooling system for dwelling house - circulates fluid through heat exchanger and through underground tank
Inventor: KUECKENS ALEXANDER
IPC: F24S90/00
Filed: 1980-06-06
Abstract: The house (1) cooling system uses a fluid to transfer heat from the house to a lower temperature underground region. The house is provided with a cold storage room (4) for food. This is fitted with a heat exchanger in the form of a pipe coil (5), connected to an underground tank (3) which contains a suitable liquid. This liquid is circulated through pipes (6-8) and extracts heat from the cold room and gives it up to the soil surrounding the tank. By fitting a heat pump (12) in the circuit the process can be reversed with the fluid receiving heat from the soil and then transferring this heat to a second fluid which is circulated through radiators inside the house.

Patent DE-3125661-A1 (DE)
Title: Method for operating an arc furnace
Inventor: MARKWORTH ERICH DR
IPC: H05B7/148
Filed: 1981-06-30
Abstract: The invention relates to a method for operating an arc furnace. In order to keep within acceptable limits the reactions on the power supply network of the load change which occurs during furnace operation, a changeover to lower or higher power is made in the event of the power consumption of the furnace being above or below the specified power consumption. The measurement of the actual values does not provide reliable values if a plurality of loads are supplied from one supply, since they influence one another. The invention overcomes this difficulty in that a model of the input supply impedance of the arc furnace has a model of the current of the arc furnace applied to it, and a voltage signal is produced which corresponds to the voltage drop. <IMAGE>

Patent DE-3131697-A1 (DE)
Title: Process for detoxifying wastes and/or pollutants
Inventor: VAHLBRAUK KARL HEINZ
IPC: C04B40/00
Filed: 1981-08-11
Abstract: In a process for detoxifying wastes and/or pollutants, in particular sewage sludge and industrial sludge, the wastes and/or pollutants are mixed with one or more hydraulically binding materials, in a fine-grain state, at a water content at least sufficient for the hydraulic binding. The mixture achieved as a result is homogenised by the input of kinetic energy effecting a constant particle acceleration of at least 1 g and subjected to colloid formation and gel formation. The input of kinetic energy achieves a permanent change of the geometrical position of the accelerated components. After this, the mixture obtained can be solidified by further hydration. During this process, hydraulic and biochemical reactions proceed, mutually supporting each other. The particles of the wastes and/or pollutants are completely encapsulated, sealed and firmly incorporated by the hydraulically binding materials and are therefore permanently and ecologically satisfactorily detoxified.

Patent DE-3141370-A1 (DE)
Title: Non-return valve
Inventor: BACHMANN LUDWIG
IPC: F16K47/00
Filed: 1981-10-17
Abstract: The invention relates to a non-return valve with a resiliently flexible seating surface, the spring characteristic running progressively. Depending on the type of design of the non-return valve, the seating surface is connected directly, or via a tubular projection indirectly, to a corrugated membrane ring. When the closing piece is resting on the seating surface and forces are acting thereon, the membrane is deformed and is supported against a stop ring as the compression forces increase. Said stop ring transmits the forces acting on it to the flange of the pipeline which is to be connected to the non-return valve. A correspondingly flexible retention of the closing piece ensures that the latter follows the position change of the seating surface.

Patent DE-3218088-A1 (DE)
Title: Bogey with two pairs of wheels for track-bound vehicles
Inventor: BERGANDER BERND
IPC: B61F5/38
Filed: 1982-05-13
Abstract: The new object consists in providing a bogey with two wheel pairs for track-bound vehicles with wheels which have a profiled tread which is adapted to wear, and to design it using simple technical means in such a way that the disadvantages occurring with wear-adapted wheel tyre profiles and the sensitivity of the dynamic behaviour with respect to fluctuations in the installation parameters of the rail are eliminated, so that the critical speed is increased in comparison with known bogeys and thus the vehicles can be used at a higher speed. In order to achieve this object, a bogey with two pairs of wheels is proposed, whose wheels have a wear-adapted profiled tread. The axles of the bogey are rigidly coupled to the bogey frame in the longitudinal and transverse direction and for each pair of wheels a switching device is provided which is controlled by a control device, which is dependent on the direction of rotation or the travel speed, in such a way that the wheels of the front pair of wheels are connected to one another in a torsionally rigid manner whilst at the same time the rigid connection of the wheels of the following pair of wheels is released.
Patent DE-3224278-A1 (DE)
Title: Multi-part mould for manufacturing objects from elastomeric materials
Inventor: GERLOFF KLAUS DIPL ING
IPC: B29D30/06
Filed: 1982-06-28
Abstract: As a result of their being statically overdetermined, multiply split vulcanising moulds such as, for example, tyre vulcanising moulds that are split radially and in the circumferential plane can only be obtained with an adequately tight sealing effect upon closing, in order to prevent troublesomerubber overflow on the mouldings, if a considerable effort is expended on fitting work. The invention achieves a valve-tight closing of all parts of the mould that fit together by utilising the plastic deformability of the mould material. The need for repeated fitting work is avoided by manufacturing the parting surfaces in question with an overdimension which is reduced to the intended specified size upon the first closing of the mould.
