Patent DE-3528867-A1 (DE)
Inventor: STENZEL OTTO DR
IPC: H05B7/152
Filed: 1985-08-12
Abstract: A compensation device for the influence of the weight of a power feed line on a weight measurement device determining the weight of an electrode and/or the melting rate in an electro-slag remelting process, in a vacuum arc furnace or the like. When an x-y device is adjusted, a weight jump occurs due to the forces of the power cable or the forces of the bellows, which has a disturbing effect on the rate definition. This weight jump can be prevented by means of mechanical devices, or can be made so small that it no longer constitutes a disturbance. However, the expenditure for this is disproportionately high. The invention is more cost efficient, since hardware or software means suffice. The weight function G=f(t) is extrapolated and compared with the actually measured weight G'=f(t). The magnitude of the difference between the two is stored and later added as a correction value.

Abstract: A possibility is provided of already collecting the waste usually occurring in private households and commercial operations at the site of occurrence in such a way that the individual proportion of waste can be emptied into each vehicle as previously and, additionally, the standing surface required for the waste container does not have to be enlarged. This possibility of collecting waste is provided by a waste container (10) with a lid (14), whose interior can be divided into at least two chambers (20, 22) which can be separated from one another and are arranged one above the other. The upper chamber (20) can be closed by the lid (14) of this container (10). The lower chamber (22) can be closed by a flap (24) which, in its position closing the lower chamber (22), forms the base for the chamber (20) located above it and can be fixed in this position. Furthermore, the flap (24) has a cutout in which the lower end of a filling tube (40) ends. The other end of this filling tube (40) ends in the region of the lid (14). <IMAGE>

Title: Device for securing an air pump
Inventor: HESSLING JOSEF
IPC: F04B39/00
Filed: 1986-04-07
Abstract: Devices for securing air pumps against theft often require changes to be made to the bicycle frame or are awkward to handle and are too expensive. Using the invention, the air pump is secured against theft without making changes to the bicycle or vehicle. For this purpose, in its handle the air pump has a cross hole above the attachment point for receiving a locking element or else a cable lock, as well as a longitudinal groove and axial centre hole for locking to the receiving pin. A lower centring point at the base of the pump additionally prevents the pump from being unlatched at the lower attachment point and from swinging away to the side.

Title: Combined lime-carbon dioxide-equilibrium-stabiliser (CLCES)
Inventor: BROZIO GERARD
IPC: C02F1/48
Filed: 1986-05-30
Abstract: The stabiliser comprises a water filter and a homogeneous magnetic field insert and is designed to give a combined apparatus. Once inserted into the water circulation, the CLCES prevents the sedimentation of lime and, moreover, slowly but continuously breaks down existing lime deposits since it stabilises the lime-carbon dioxide equilibrium (DIN 4046) by strong and highly concentrated homogeneous alternating magnetic fields. In general it can be stated that the apparatus can be used anywhere where lime sedimentation problems exist.

Patent DE-3730789-A1 (DE)
Title: Nuclear power station with a high-temperature reactor
Inventor: SCHOENING JOSEF DIPL ING DR
IPC: G21C9/02
Filed: 1987-09-14
Abstract: The invention concerns a nuclear power station with a gas-cooled high-temperature reactor that is located eccentrically within a cylindrical reactor pressure vessel, and whose core is formed by spherical fuel elements. The high-temperature reactor is characterised by a special geometry; for example, it is rectangular or elliptical in cross-section, so that it is possible to perform all shut-down procedures with only the help of absorber rods that can be moved in the side graphite reflector, even at higher outputs. This enables a flow upwards through the heaped core, so that no additional thermal stresses on core internals occur during residual-heat removal by natural convection. The heat utilisation system, consisting of e.g. steam generators, is located in a second area within the reactor containment structure, lying next to the first area containing the nuclear reactor; the relative position of the two components is fixed so that a relatively small diameter of the reactor pressure vessel results. The primary coolant flows downwards through the heat utilisation system, and the secondary coolant upwards.
