Title: Tool for desoldering multi-legged electronic components
Inventor: MAJEWSKI PETER
IPC: H05K13/04
Filed: 1984-12-07
Abstract: According to the methods which have been known by me until now for detaching multi-legged electronic components from printed-circuit boards, this process is very expensive, to some extent position- dependent or can also be technically implemented only with difficulty. Using the tool which I have invented, which simultaneously heats the IC and pulls it off the printed-circuit board, this problem is not only solved in a technically correct manner, independently of position and cost-effectively, but the IC has double protection against overheating during desoldering.   1) Since the process lasts only a few seconds and the solder in this case does not even need to be made fluid. 2) Since the heat flow in the direction of the IC is dissipated via an additional heat sink. s

Title: Process and apparatus for carrying out the process of separating out NOx downstream of already-installed flue gas scrubbers for separating out SO2 or flue gases which only have NOx pollution
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-03-05
Abstract: It has already been proposed to use single- and/or multiple-stage scrubbers in order to separate out SO2 and NOx from flue gases. The second stage after the SO2 scrubbing is provided for separating out NOx. In order not to carry out a particular stage in the form of a scrubber downstream of an already-installed SO2 scrubbing, but to use already-installed so-called clean gas channelling as scrubbers, according to the invention it is proposed that the so-called dirty and/or clean gas channels are used as scrubbing tubes, into which mist eliminators (4) are inserted, and the water conducted away from the mist eliminators is fed to a filter plant, separated from solids here, fed to an electrolysis (5) and from this, having an appropriately provided redox potential, is fed to a regeneration vessel (7). In the regeneration vessel (7) an appropriate residence time is provided which is predetermined in relation to the necessary degree of scrubbing out, where the redox potential is to be seen as negative relative to calomel with 3 molar KCl solution and according to the invention is not negatively influenced by the oxygen portion of the flue gas in the reduction phase. The scrubbing section is sprayed with the appropriate scrubbing liquid from the redox vessel (7) via a pump (8) via scrubbing water nozzles (3) (Figure). <IMAGE>

Filed: 1985-05-04
Abstract: A hand-held machine tool (1) with an electric motor drive is proposed, which has a power connection (10/11) for additional apparatuses (3) which can be electrically operated. When mains power is used, the mains voltage which is fed in is passed via an electrical component (13) to the additional apparatus connection (10) and in the process is reduced to a safe, low protective voltage of less than 42 V. In this way, use of the hand-held machine tool (1) with additional apparatuses (3) is simplified. The additional apparatuses (3) can be of less costly design and nevertheless satisfy all the safety regulations. <IMAGE>

Patent DE-3538231-A1 (DE)
Title: Process for reprocessing waste solutions
Inventor: HOFMANN GUENTER
IPC: B01D53/68
Filed: 1985-10-24
Abstract: The invention relates to a process for reprocessing waste solutions from processes in which substances are treated with the solutions, in particular flue gases are purified, and in which the waste solutions, in addition to dissolved alkali metal chlorides and sulphates and alkaline earth metal chlorides and sulphates and typical impurities, contain an organic acid in the form of a salt, in particular calcium formate, by single- or multiple-stage evaporation in vacuo with crystallization of the alkali metal chlorides and sulphates and alkaline earth metal chlorides and sulphates and subsequently separating off the crystallized solid via a separation stage. In order to eliminate the disadvantages occurring in the processes known hitherto and simultaneously reduce the costs for the consumption of chemicals (organic acid or salts thereof) and to produce a calcium chloride product as pure as possible, it is proposed that a portion of the mother liquor from the crystallization stage is returned to the treatment stage of the process, in particular into the scrubber circulation of a flue gas purification plant, or into process stages which serve the treatment stage. <IMAGE>

Title: Extending table with a rotatable extension leaf
Inventor: HECKMANN PETER
IPC: A47B1/02
Filed: 1986-02-08
Abstract: An extending table consists of two table leaves lying on a frame and an extension leaf arranged in a rotated manner underneath. The table leaves can be jointly moved apart in the horizontal direction by an operator by means of a coupling device, by displacing one of the two table leaves. The coupling device serves as a rotary drive for the extension leaf. The extension leaf and part of the coupling device are held on the frame so as to be pivotable about a vertical pin which is also vertically displaceable. Through the coupling device, the extension leaf is rotated from a rest position through approximately 90 DEG  into a raisable position and raised to the level of the table leaves. The rotary movement of the extension leaf is substantially brought about by a U-shaped driver which takes hold of a driving pin fastened to the extension leaf. As a result of the position of the extension leaf rotated through approximately 90 DEG in its rest position underneath the table leaves, it is possible to conceal the entire mechanism arranged under the table leaves, as well as the extension leaf, without covering strips at the outer edge of the table leaves. By the additional use of the coupling device as a rotary drive for the extension leaf, the mechanism of the extending table is considerably simplified.
