Title: Turning process for machining pockets in bearing cage and similar parts - involves feeding rotating workpiece towards tool tip rotating in circular path to scoop out pockets in successive revolutions of workpiece
Inventor: BOHNACKER MOHAMED DIPL ING
IPC: B23Q27/00
Filed: 1992-04-11
Abstract: The ring (10) to be machined rotates on a spindle and slide which can be fed towards the cutting tool (14).

Title: Use of liq scrubber for concentrating pollutants in an air stream - eg for subsequent combustion, includes liq scrubbing desorbing pollutant in sec higher temp step to sec lower flow rate air stream.
Inventor: KIRCHNER-REINHARDT ROBERT DR I
IPC: F23G7/06
Filed: 1992-10-09
Abstract: Process for concentrating-up toxic gas and vapours in an air stream, novel in that in a first step the pollutant is removed from the air stream by scrubbing with a suitable liquid (washing medium), and in a second, higher temp step is transferred (desorbed) to a secondary, lower flowrate, air stream to produce a higher concn. The pollutants in an airflow of 10,000 m3/h (1) were concentrated by transfer to a secondary airflow (4) of 400-800 m3/h. The pollutant in stream (1) was a mixture of xylene isomers at a level of 0.5gm/Nm3, its concentration in secondary air stream (4) was 5-10 gm/Nm3 ie a concentration factor of 10x-20x. The concentrated air stream (4) could then be fed to a thermal decomposition unit. USE/ADVANTAGE - Concentration of pollutants from very dilute air streams to facilitate subsequent treatment/disposal. Avoids problem of desorbing high boiling point substances with hot air, at limited upper temperatures, form solid adsorbents such as activated carbon, and also the problems caused by irreversible clogging of such adsorbents by entrained solids (eg paints, varnish etc).

Title: Processing waste water with salt content and volatile matter - has a second electrodialysis stage for further concn. and diluate feedback
IPC: B01D61/44
Filed: 1993-05-25
Abstract: To process waste water with a salt content, and also volatile components, it is passed through a series of modules each with at least one diluate chamber with a membrane separation from a concentrate chamber as an electro-dialysis stage, in part flows against each other through the module. The concentrate is passed to a further similar electro-dialysis stage for further concentration, and the dilute from this stage is returned to the flow of fluid to be dialysed at the preceding stage. Also claimed is an assembly with a second electro-dialysis unit (1b) after the first (1a) where both their entry chambers (4b, 5b) are connected to the preceding stage (1a). The diluate outflow chamber (5b) is connected to the preceding stage (1a). Pref. the salt concentrations are established in the fluid to be dialysed and the diluate from the further stage. If the diluate has a higher salt concn. it is passed to the diluate chamber of the preceding stage, and if it has a lower salt content, it travels to the concentrate chamber of the preceding stage. The concentration from the second stage is passed to an evaporator with a cndensation stage, and condensation is returned to the preceding electro-dialysis stage. According to the salt content of the fluid to be dialysed and the diluate of the second stage, the condensation is fed under vol. control at least to the entry chamber of the successive diluate chambers. The presence of volatile matter is measured in the condensation and, from a given level, it is fed at least partially to the entry chambers of the successive diluate chambers. USE/ADVANTAGE - The system processes waste water with a content of salt and volatile matter, with reduced energy consumption through the stability of the modules.

Title: Motor vehicle window pane antenna
Inventor: FUCHS ANDREAS
IPC: H01Q1/12
Filed: 1993-07-12
Abstract: It is known for the heating conductor structure in the rear window panes of motor vehicles to be used as a passive component of active broadcast radio receiving antennas. It is also known in the case of such an arrangement for the signal to noise ratio to be improved and the gain to be increased by arranging one or, for example, two secondary conductor tracks in or on the window pane, which conductor tracks run orthogonally with respect to the existing conductor tracks which run virtually horizontally. According to the invention, the secondary conductor tracks (7) are routed as far as the lower edge (9) of the bodywork opening and are connected in RF terms there to one or two further conductor sections (8, 10) which is or are arranged symmetrically with respect to the centre of the window pane and at a distance of 5 to 10 mm from the metallic bodywork edge (9), as well as parallel to said bodywork edge. The total length (A) of the conductor track arrangement (7) is approximately 400 mm for VHF reception. By changing primarily the length and separation dimensions of the conductor track arrangement (7), it is possible to balance the output impedance of the antenna structure in the window pane, with a tolerance of at most 10%, to the input impedance of the antenna amplifier and decisively to reduce the previously problematic losses resulting from incorrect matching. At the same time, a single amplifier circuit, some of which can be prefabricated, can be used from now on for any desired vehicles and for any desired rear window panes, using the antenna structure described initially. <IMAGE>
