Title: Process and plant for treating gases and vapours
Inventor: RENNEBERG JOHANN DIPL ING
IPC: B01D53/62
Filed: 1983-11-29
Abstract: A process for treating gases and vapours and a plant therefor are to enable treatment of combustion gases from waste oil incineration and heavy oil combustion with the lowest possible production of waste water. For this purpose it is proposed that the flow medium in the form of combustion gas coming from a waste oil incineration or heavy oil combustion or the like is directed through a flow path having changing cross-section and is therein deflected in a meandering fashion, the flow medium passing through spray mist composed of scrubbing water kept in the pH range of about 6 to 7 and the reactant Ca(OH)2 is used. In this case, the flow medium is to be cooled prior to the absorption process by evaporation and heat exchange to at most 150 DEG C. In this plant a multiplicity of absorption chambers are provided next to each other in a housing. Furthermore, upstream of the first absorption chamber is connected an evaporator through which the flow medium passes and, preferably, a hydrogenation device which is a hydrogenation coil, the solids intake of which is assigned to the outlet end of the evaporator and the solids outlet of which is adjacent to the inlet for the flow medium. <IMAGE>
Patent DE-3343442-A1 (DE)
Title: Multi-purpose stage with lowerable front part
IPC: E21D9/12
Filed: 1983-12-01
Abstract: Provided for roadway driving and roadway maintenance is a multi-purpose stage which, apart from the working platform arranged as usual so as to be liftable and lowerable, also has a sectional platform, liftable and lowerable separately from the working platform, in the front area. This sectional platform is lifted and lowered separately from the working platform via a parallelogram-link-like mechanism so that there is a safe place to stand for the operating crew even if the working platform has to be arranged relatively close below the roof on account of the loading vehicles working and moving to and fro underneath. It is thereby possible to use multi-stage platforms of this type even in roadways with a small cross-section. <IMAGE>

Title: Split fuel element for a nuclear reactor, in particular a boiling water reactor
Inventor: LOVINCIC MIROSLAV DIPL ING
IPC: G21C3/328
Filed: 1984-01-12
Abstract: Fuel elements (1), in particular for boiling water reactors, have gaps (8), which extend at right angles to the rim of the cross-section and are as wide as the fuel element, in order to influence the moderator ratio. In the invention, the gaps (8) reach over the upper part of the fuel element (1), while the lower space adjoining in the longitudinal direction contains fuel rods (12) which are correspondingly shorter than the fuel rods (13) situated between the gaps. As a result, a higher fuel element power is achieved in the upper part, and thus the axial power distribution is also flattened. <IMAGE>

Patent DE-3405074-A1 (DE)
Title: Float valve
Inventor: ALTMANN KONRAD DIPL PHYS DR
IPC: F16K31/08
Filed: 1984-02-13
Abstract: The invention relates to a float valve for a cistern, which valve is additionally controlled by a magnetic coupling in such a way that the valve remains fully opened during the entire filling process and rapidly closes when the cistern is full, if the lifting force of the float is sufficient to disconnect the magnetic coupling. In order to avoid a recoil, it is proposed to configure the float such that fluidic damping occurs. This can be achieved, inter alia, by a cavity in the float, by means of which the effective inert mass of said float increases. Furthermore, a magnetic damping process is proposed.

Patent DE-3442574-A1 (DE)
Title: Single-track motor vehicle
Inventor: OHL HERBERT DIPL ING
IPC: B62D61/02
Filed: 1984-11-22
Abstract: The subject of the invention is a single-track motor vehicle with electromechanically closed-loop controlled and mechanically open-loop controlled equilibrium sensitivity. A novel arrangement of a single-track motor vehicle, with a cabin which has four to five places, for substantially improving the power-to-weight ratio and the aerodynamics with a view to increasing travel comfort to an optimum degree by virtue of driving free of centrifugal forces and by a vertical, convenient way of getting-in and getting-out and by considerably reducing the technical and economic expenditure for operating and producing the motor vehicle and by eliminating and reducing components, their requirement for energy, weight and space is shown, the equilibrium position being detected by means of sensors and being ensured via a central processor via mechanical control elements in order to laterally displace at least one of the wheels of the vehicle. The lateral offset of the wheels of the vehicle ensures automatic, continuous compensation of equilibrium for all travelling states and load states free from the sensomotive co-operation of the driver of the vehicle who merely carries out monitoring of the direction of travel and of the speed.

Patent DE-3447328-A1 (DE)
Title: Method for preventing the load transformation in useful-power generators of all types
Inventor: STEIN MICHAEL CARL-HERMANN
IPC: G05F1/67
Filed: 1984-12-24
Abstract: It is known that useful-power generators of all types change their characteristic when loaded. This change in characteristic has the disadvantage that the advantages of the unloaded system state, the so-called no-load state, are lost. It is thus known that, for example, one motor can drive a series of n generators under no-load conditions. It follows from this known empirical fact that it would be ideal if these no-load characteristics could also be maintained under loaded system states and thus be utilised for generating useful power. The invention achieves this object by the fact that it avoids load transformation and is characterised in the main feature by the fact that its method prescribes that the value of the total external impedance Ra ges. is ideally equal to 2 Ri, as a result of which the no-load characteristic of the useful-power generator is retained and thus also the primary energy potential can be correspondingly utilised with improved overall efficiency.

Patent DE-3527919-A1 (DE)
Title: Process and device for producing a composite panel
Inventor: WESSEL KARL-HEINZ DIPL ING
IPC: B29C53/04
Filed: 1985-08-03
Abstract: First a composite panel having a continuous cover panel full-area glued onto the top side, the rounded edge and the underside of the core panel is produced. To this end, starting from the rounded edge, the cover panel is glued first of all onto the rounded edge and then onto the top side on the one hand and onto the underside on the other hand of the core panel. For this purpose, the core panel is preferably in an essentially vertical position with an upwardly directed rounded edge. It is of particular advantage if the cover panel is then glued onto the rounded edge of the core panel with the aid of a flat pressure surface which is rolled on the edge, specifically without movement relative to the cover panel in a tangential direction. This pressure surface must then execute a tumbling movement which is superimposed from an involute and a counter-involute and this leads to the result that neither sliding friction nor rolling friction occurs. The flat pressure surface has the further advantage that it forms a large heat transmission surface as regards the cover panel and thus permits ready heating-up of the cover panel in the region to be bent over by contact heat alone. Metal pressure distribution plates on the edge-forming plungers finally ensure a uniform pressure distribution over the entire surface of the top side and the bottom side of the core panel.

Title: Process and plant for preparing sizing
Inventor: BASIN LEONID ABILJAROVIC
IPC: C08B30/12
Filed: 1985-08-28
Abstract: The process for preparing sizing in the plant comprises carrying out the suspension of starch products in the water in a vessel (1, 2) at a temperature beneath the temperature of the initiation of gelatinization of starch products. The suspended starch products are then fed to a cooker (16). Magnetostrictive converters (17) are mounted on the opposite walls of the cooker (16) for conversion of electrical energy into ultrasonic energy, which cleave the starch products by ultrasonic action with a cavitation developing in the total volume of the suspension to be treated, until the temperature of the gel forming has exceeded the temperature of initiation of gelatinization of the starch products by 12 to 15 DEG C. The invention can be used for preparing the sizing which is applied to the warp threads for improving their physical/mechanical properties prior to weaving. <IMAGE>
