Title: Process and arrangement for detoxifying fluorocarbon-containing exhaust gases
Inventor: TILLER HANS-JUERGEN DIPL PHYS
IPC: B01D53/70
Filed: 1984-08-31
Abstract: The process and arrangement for detoxifying fluorocarbon-containing exhaust gases, such as are produced in particular in plasma processes, has great importance in the avoidance of environmental pollution by exhaust gases which are enriched in pollutants. The object of the invention is the complete and effective elimination of such pollutants. This object is achieved by a process in which a reaction is brought about using SiO2 as a solid at atmospheric pressure and at a temperature of at least 500 DEG C. An increase in the temperature to 700 DEG C limits the reaction duration to about 2 minutes. To carry out the reaction, an apparatus can expediently be used which contains a flow tube having a surface made of a suitable oxide. The apparatus can contain a multiplicity of reactor tubes operating in parallel; means for vortexing the solid in the exhaust gas stream can also be provided. However, the reaction can also be carried out in a closed volume having corresponding feed and discharge lines. The solid reactor can be coupled to a hydrolysis device for destroying SiF4, HF and COF2.

Title: Device for the exposure and separation of photographic sheet material for the production of borderless copies
Inventor: THADDEY KURT
IPC: G03B27/58
Filed: 1984-09-29
Abstract: A focal plane shutter (32) exhibits two shutter blinds (35, 36) with associated blind rollers (33, 34), which can be driven by stepping motors (M3, M4). The transport and positioning of the sheet material (6) along the paths of movement of the shutter blinds (35, 36) are effected by a positioning roller (14) which can likewise be driven by a stepping motor (M2). The stepping motors (M2, M3, M4) are digitally controlled by pulses from positioning devices. Before the exposure of a sheet portion by a projected image (31), the sheet material (6) is positioned so that its leading transverse edge (6k) has, from the optical imaging axis (OA), a spacing which amounts to one half of the image format length. To make the exposure, the shutter blinds (35, 36) are moved in succession in the same sense, so that their closing edges (35k, 36k) release the sheet portion and then cover it over again. One (31uk) of the image edges of the exposed image (31) is formed by the transverse edge (6k) of the sheet material (6), and the opposite image edge (31ok) is masked by the shutter blind (35), which is situated on the other side of the optical imaging axis (OA). In the exposure position, the closing edge (35k) of this shutter blind (35) has, from the optical imaging axis (OA), a spacing amounting to one half of the image format length. By altering the programme of the positioning devices, the device can be adapted to differing image format lengths. <IMAGE>
Patent DE-3437237-A1 (DE)
Title: Tunnel furnace with two parallel ducts
Inventor: RIEDEL RUDOLF
IPC: F27B9/02
Filed: 1984-10-08
Abstract: The tunnel furnace serves for the heat treatment of for example clay or porcelain and is a so-called counter-running furnace, in which the product stacks are guided in opposite directions through the two ducts. The ducts are separated by a central wall provided with passage openings above and below the product stacks and are subdivided in each case into a heating zone, a firing zone and a cooling zone. Between the heating zone of one duct and the adjacent cooling zone of the other, cross-convection takes place, which makes the heat of the cooling zone useful in the heating zone of the other duct. This cross-convection is disrupted by a longitudinal convection, which flows between the firing zone and the outside atmosphere, in such a manner that the heat balance of the furnace, which in itself is very favourable, is worsened. The invention now provides, above and below the product stacks (P1, P2) in each duct (1, 2), vertical flow guide plates (12) which form in the direction of transport (T1, T2) of the products an angle ( beta ) of less than 90 DEG  with the central wall (3) and in each case end next to the passage openings (10) on the central wall. On each guide plate, part of the longitudinal convection is in this case deflected in the direction of the cross-convection so that the longitudinal convection is weakened from guide plate to guide plate and at the same time contributes to the propulsion of the cross-convection. Additionally or alternatively, each duct can also be assigned ventilation means which, in the region of the duct ends, ... Original abstract incomplete. <IMAGE>

Patent DE-3440076-A1 (DE)
Title: Process for preparing a milk of lime from slaked lime, water, waste water and/or sewage sludge, and apparatus for carrying out the process
Inventor: PANHOLZER WOLFGANG
IPC: C02F1/52
Filed: 1984-11-02
Abstract: The process is primarily intended for use in waste water engineering.   The known batchwise preparation has relatively large space requirements and an elevated energy consumption since it is necessary to continue to operate the mixer after removing the batches (idling).   The object is therefore to provide a process which uses appliances which can be of small dimensions and whose energy consumption is low.   The solution provides that the preset portion of slaked lime is continuously removed from the stock container 2 and is converted into a suspension by combination and mixing in a through-type mixer 9 with the proportion of water, which is also supplied continuously. The combination of the individual components in terms of proportions and the rate at which they are added can be set by control elements 11, 13 and 14. The finished product is removed by the metering pump 12 and is primarily used in disinfecting sewage sludge in order to precipitate solids and pollutants and to condition sewage sludge to be supplied to downstream dewatering appliances. <IMAGE>
