Title: Metallurgical reaction vessel, in particular a steelworks converter
Inventor: KOEPER WILHELM
IPC: C21C5/46
Filed: 1983-08-22
Abstract: Such metallurgical reaction vessels, in particular steelworks converters, are provided with an internally cooled outlet protection which is connected to a cooling channel system and built up on a front ring which is fixed to the vessel shell and extends perpendicularly to the central longitudinal axis of the vessel and to which exchangeable outlet rings in one or more parts are fixed. To avoid distortion stresses and to limit wear of the parts exposed to the exit gas heat or to the so-called slag bears, it is proposed that the outlet protection is divided into an uncooled, radially inner outlet ring (14) and a forcibly cooled, radially outer cooling ring (6). A convenient embodiment is designed in such a way that, in the radial region (5) of the front ring (4), an outer cooling ring (6) is provided which, relative to the central longitudinal axis (3) of the vessel, by means of axial outer spacers (7a and 7b) and together with the front ring (4), forms a front spacing chamber (8) in which cooling tubes (10) are arranged, and that an exchangeable inner outlet ring (14) in one or more parts is joined via additional axial, inner spacers (13) to the front ring (4). <IMAGE>

Title: Process for the continuous supply of solid reagents, especially lime granules into fluidised bed furnaces
Inventor: HARTMANN HEINZ LEOPOLD DIPL IN
IPC: F23C10/28
Filed: 1983-12-05
Abstract: The invention is intended to propose a process for the admixing of lime into coal to bind sulphur, the said process reacting very sensitively to fluctuations in the sulphur content of the coal and to any residual content of sulphur in the exhaust gas, and immediately compensating for these by compensating, counteracting control measures. This is achieved when the solid reagent, especially the lime granules, is mixed with the combustion air and transported by this, and this solid-air mixture is blown into the fluidised bed at a plurality of feed points serving to supply combustion air, an adjustable, constant and low blowing velocity (about 3-4 m/sec) being selected. The admixing of the solid reagent, especially the lime granules, to the combustion air takes place variably and is adjusted, with free selection, in closed control circuits, in dependence on the expected average sulphur content of the coal at any given time, and also in dependence on the quantities of coal supplied as recorded by the coal metering appliance at any given time and on the residual sulphur content recorded in the flue gas at any given time.

Title: Set of structural elements for scaffold bridges
Inventor: BRAEUTIGAM ERICH
IPC: E04G1/15
Filed: 1984-08-31
Abstract: Known working platforms, made up of individual structural assemblies, for scaffold bridges, may be altered in terms of length but not in terms of the overall height, with the result that in particular scaffold bridges with small and average spans require a high material outlay. 
<??>The set of structural elements according to the invention allows scaffold bridges of varying lengths and overall heights to be designed, this leading to a saving in materials and low weight. The set of structural elements comprises a main segment and two shorter side segments, which, according to the overall length of the scaffold bridge, can be trussed by pairs of standardised tension and compression bars. For this purpose, four pairs of connecting straps are arranged on the main segment in such a manner that the distance between the outer connecting straps corresponds to the length of a long tension bar and the distance between an outer connecting strap and the neighbouring inner connecting strap corresponds to the length of a compression bar. Guides for locking rods for fine adjustment and supporting of the working platform on scaffold towers or the like are arranged at both ends of the main segment and at in each case one end of the side segments. The working platform can be used expediently for repair and reconstruction work on buildings.

Patent DE-3517279-A1 (DE)
Title: Automatic downpipe flap
Inventor: WANDEL OTTMAR
IPC: E03B3/02
Filed: 1985-05-14
Abstract: Gutter downpipe having a downflow-water-controlled lateral outlet for rainwater. In order to be able to use rainwater which falls on roof surfaces, it is necessary to divert the water out of the roof gutter downpipe. However, the precipitation occurring rinses many harmful deposits off the roof, in particular after prolonged dry spells. If the water is contaminated by such deposits, it can be used only poorly. It is ensured by the invention that only clean rainwater is diverted. This is achieved by the flap (8), which is closed just a short time after it starts raining by the weight of a container (11), which is located inside the downpipe (2) and slowly fills with water when it starts raining. When the flap (8) is in the closed position, the water is diverted sideways. It can be used for irrigation and ground water enrichment. Also, when precipitation is heavy, it provides considerable relief for the water treatment systems. <IMAGE>
Patent DE-3523270-A1 (DE)
Title: System for transferring values of a two-dimensional vector to a data processing device
Inventor: SCHADE GUENTER DIPL ING
IPC: G06F3/038
Filed: 1985-06-28
Abstract: A device, e.g. a disk cam (SS) can be activated by an operator to transfer values of a two-dimensional vector to a data processing device, e.g. a display screen. The movement of the disk cam (SS) is sampled using at least two sensors (SOR) arranged perpendicularly with respect to each other. Each sensor emits a sensor signal (sor) depending on the excursion of the disk cam (SS) at the position of the sensor (SOR). An evaluation circuit (MC) forms an excursion vector (VA) from the sensor signals (sor). The evaluation circuit then generates a change vector from the excursion vector (VA), and the direction of the change vector corresponds to the direction of the excursion vector and the amount of the change vector is generated from the amount of the excursion vector using an optional reference specification, and indicates the amount of the value change per time unit. With this system, the disk cam can, for example, be operated so as to very quickly and yet accurately move a screen marker or the frame outlining a section of the screen to be magnified to the required point on the screen or to a given area of the overall picture. <IMAGE>
