Patent DE-3401738-A1 (DE)
Title: Ventilation apparatus, preferably for a flat roof
Inventor: ESSMANN PETER
IPC: E04D13/14
Filed: 1984-01-19
Abstract: Ventilation apparatuses for buildings with flat roofs comprise a mounting ring, fastened on the roof, and a flap or dome light fastened to the upper edge of said roof. Due to the structure and design of a flat roof, renewal is often necessary after a few years. Renewal consists in that an additional roof skin and a further insulating layer are attached. As a result, the distance between the upper roof skin and the upper edge of the ventilation apparatus is reduced to a dimension which is no longer permissible. Incorporation of a new dome light with a corresponding overall height is not acceptable, however, for reasons of cost. In the case of the ventilation apparatus according to the invention, a build-up ring is provided between the mounting ring and the ventilation flap, which build-up ring is firmly connected to the mounting ring and on the upper edge of which the ventilation flap is articulated. Furthermore, to avoid joints which are not sealed, the renewal material is fixed in the upper region of the build-up ring. Said build-up ring, which is in the shape of a parallelogram when viewed in cross-section, can particularly preferably be further provided with an insulating core (Figure 1). <IMAGE>

Title: Device for burning weakly radioactively contaminated waste
Inventor: MUENTZEL WOLFGANG ING GRAD
IPC: G21F9/32
Filed: 1984-02-11
Abstract: The subject-matter of the application is a device for burning weakly radioactively contaminated waste from nuclear power stations. It is conventional to compress such waste by applying high-pressure presses to a small volume, or to separate the combustible material from the non-combustible waste and to reduce its volume by burning it. In order not to have to transport the waste for this purpose to large incinerators, for example abroad, the invention provides an incinerator which is designed for the waste volume of a single nuclear power station and is configured such that its exhaust air corresponds to the degree of purity of the exhaust air which is present in any case in the compartments of a nuclear power station, so that it can be introduced into these compartments. For this purpose, the device is provided with a combustion chamber (4), a cyclone (6), a cooler (9) and filters (10, 11') arranged in a closed container (18) which is provided with an exhaust air outlet (23) for the combustion gas. Moreover, the container (18) is provided with an inlet opening (1) for the waste and an outlet opening (24) for the ash, of which preferably the one is arranged in the roof and the other (24) in the floor of the container (18). <IMAGE>

Title: Process to achieve complete biological nitrification in drinking water
Inventor: BREITENBAUM RONALD
IPC: C02F3/34
Filed: 1984-03-02
Abstract: To achieve a complete conversion of ammonium ions in drinking water, in particular in the presence of elevated contents of heavy metals such as iron and manganese and the frequent backwash intervals resulting therefrom in an existing filter plant, which lead to a partial destruction of the microbiological layer on the filter layers, nutrient solutions based on phosphorus salt-containing compounds of monomeric structure are added to the untreated water before the filtration stage. As a result, the development of the biological lawn in the filter plant is decisively supported and its structure is strengthened so that, by this process, a complete biological nitrification and thus drinking water quality is achieved.

Title: Magnetoelastic dynamometer
Inventor: RATHGEBER HERMANN DIPL ING
IPC: A01B63/112
Filed: 1984-08-09
Abstract: A magnetoelastic dynamometer (10) is proposed which has in its interior, in a tubular bolt (11) made from ferromagnetic material a transformer transmitter (13) in the region of a shear zone (18). The transformer transmitter (13) has a cruciform magnet core (20) which bears with its four pole faces (21 to 24) against the wall of the bore (12) in a plane extending through the longitudinal axis (19) of the bolt bore (12) and has a central flux guidance part (25) which is common to the magnetic fluxes of the excitation coil (25) and the measuring coil (27) situated at right angles thereto. Changes in permeability occurring in the bolt (11) under load lead to a secondary flux which flows through the measuring coil (27) and extends transversely to the primary flux and whose induced voltage produces a signal proportional to the force (F) applied to the bolt (11). <IMAGE>
Patent DE-3433292-A1 (DE)
Title: Apparatus for the directed deflection or screening of so-called earth radiation - geopathogenic zones - and other sources of interference, such as television antennas and high-tension-line towers and of other radiators
IPC: A61N1/16
Filed: 1984-09-11
Abstract: Antennas - bar antennas, V-shaped multiple-bar antennas, spirals, in connection with tubular sleeves which serve as wave guides and are or may be equipped with a ground reflector to increase their effect, emit all around a deflecting radiation or an interference radiation in the upright position in conjunction with a directional reflector mounted at the top, charged by a geopathic wave field. This radiation is capable in its effective range of drifting or neutralising other interfering stimuli/radiation caused by further interference zones (water veins, etc.). In the case of interference radiation/deflection radiation directed downwards due to a corresponding reflector shape there is no rod deflection above the erection site. In the case of interference radiation/deflection radiation directed upwards due to a corresponding reflector shape there is no rod deflection below the erection site. The effective range is influenced by the size of the antenna, the charge thereof (interference zone crossing) and by the shape of the reflector screen.

Filed: 1985-01-14
Abstract: For the purpose of preventing or limiting the strong oscillations of the nozzle needle and the pronounced, undefined fluctuations of the flow of fuel through the nozzle opening which are associated with this, and to prevent the increased wear of the nozzle needle, the nozzle seat and the slide face in the nozzle body thereby occurring and in order to maintain a permanent, uniform spray pattern, in this injection nozzle grooves (6) are arranged in the surface of the truncated-cone-shaped pressure shoulder (1), lying symmetrically opposite at an empirically determined angle ( alpha ) or regularly distributed on the circumference, so that as the nozzle needle moves towards the seat a vertical force (Pv) delaying the downwards movement, a tangential force (Pt) causing the phased rotation of the needle, and a force (Pn) perpendicular to the groove come to operate in the heavily compressed fuel of the pressure chamber on the circumference of the pressure shoulder, as a result of which an increased friction loss and swirl loss is produced at the grooves (6) and at the pressure spindle as a function of the angle ( alpha ), the groove depth, their number and with the overcoming of the moment of inertia of the needle, resulting in a heavily direction-dependently damped oscillation with a simultaneous rotation of the nozzle needle.

Patent DE-3616376-A1 (DE)
Title: Internal combustion engine
Inventor: RUMMEL HARALD
IPC: F02B53/00
Filed: 1986-05-15
Abstract: The invention relates to an internal combustion engine functioning according to a new process. A circular disc, corrugated in the middle, performs a reversing 90-degree movement in a spherical cylinder. The spherical cylinder has a V-shaped notch at the top and bottom. The notches are bolted to cylinder heads. Two cylinders are produced, which are controlled from above and below, that is four combustion chambers. A continuous 720-degree rotational movement per working cycle is produced by means of a crankshaft drive. The rotational speed of the crankshaft drive is halved by means of a gear drive. The internal gear on the main shaft, which is moved by the crankshaft drive, now rotates 360 degrees per working cycle and serves as control shaft for valves and ignition system. The actuation of the valves is transmitted by pushrods. The engine ignition system receives its pulse from a sensor, which is located on the control shaft of the engine. For starting the engine, the crankshaft is made to rotate by a pre-engaged-drive starter motor.
