Patent DE-3826827-A1 (DE)
Title: Device for positioning workpieces
Inventor: DEGNER HELMUT DIPL ING
IPC: B21D43/10
Filed: 1988-08-06
Abstract: Coordinate tables (1) are known where a lower carriage forming the supporting surface for a workpiece is mounted so as to be displaceable towards a machine tool, an upper carriage carrying clamping devices for the workpiece being displaceable relative to the lower carriage. For rapid and accurate positioning of large and, especially, heavy workpieces, powerful drives must be used to match the masses to be moved and the supporting structure is correspondingly complex and, in particular, massive in order to achieve low-vibration operation. To avoid these disadvantages, a supporting table (2) is arranged fixed in the frame of the apparatus according to the invention, whereas a guide system (4) comprising a lower carriage (13) and an upper carriage (23) is displaceable on a supporting frame (10) along the longitudinal edge (31) of the supporting table. The upper carriage (23) is displaceable relative to the lower carriage (13) perpendicularly to the longitudinal edge (31) and bears clamping tongs (6) for grasping the workpiece (3). Given the lower masses to be moved in the displacement of the workpiece (3) in comparison with conventional coordinate tables, a more rapid positioning movement is obtained for a given expenditure of energy for the displacement. <IMAGE>

Title: Process for biological waste water purification
Inventor: SCHOENBERGER RAINER
IPC: C02F3/12
Filed: 1988-09-30
Abstract: The invention relates to a process and an apparatus for biological waste water (effluent) purification, in addition to organic carbon compounds, nitrogen compounds also being removed from the waste water. For substantial elimination of the nitrogen compounds, it is proposed to feed the waste water initially to an anaerobic contact tank 2, downstream of which is connected a sedimentation tank 6 in which the anaerobic sludge is separated from the overflow. The overflow is introduced into a subsequent nitrification stage 8, while the anaerobic sludge is fed to a denitrification stage 10 connected downstream of the nitrification stage 8. An activation tank 13 can be connected downstream of the denitrification stage 10. By means of the invention, a separation into anaerobic sludge principally containing carbon compounds and overflow containing virtually the entire nitrogen loading is achieved so that conditions optimal for the removal of nitrogen can be established in the denitrification stage 8. <IMAGE>

Patent DE-3920647-A1 (DE)
Title: Fluorescing luminaire device
Inventor: WATANABE HIROSHI
IPC: G09G3/30
Filed: 1989-06-23
Abstract: A fluorescing luminaire device which is capable of driving a number of control electrodes by means of driver circuits which have a reduced number of pins or connections for output, leads to a considerable reduction in the production costs for the device. Several of the control electrodes are optionally driven in the group without a number of output connections of the driver circuits being required which corresponds to the number of control electrodes, which has the result that a number of control electrodes is driven by the driver circuits with a reduced number of output connections. A negative voltage is furthermore applied to those control electrodes whose optional drive is not desired, so that faulty displays can thus be avoided.

Title: Ring spinning frame - has revolving cutter blades at base of spindle which activate after doffing
Inventor: KAMP HEINZ
IPC: D01H9/16
Filed: 1989-08-02
Abstract: On a ring spinning frame, in the region of the base of the spindle, there is a fixed and a revolving blade, co-axial to the spindle, with at least one indentation per blade, to cut the yarn. Pref. on the ringspinning frame, the drafting zone (3) carries yarn (4) across a thread brake (10) and eyelet (5), which holds the yarn as doffing takes place. The doffer (11) also has a thread brake (11'), so that the yarn is brought across the spindle (8) into the traveller on the ring, on the ringrail (7) when at the commencement of traverse. The yarn (4) is held in the grip at the base of the spindle which permits a moving cutter blade (14) and running counter to the fixed cutter blade (13), to sever the yarn when the spindle commences to revolve. The dia. of the cutter blades is less than the ring dia. With other doffing methods, the cutters are surrounded by yarn guides, by which means the yarn is retained at the point of severance until the spindle revolves, commencing the spin, and releasing the yarn end from the full cop. ADVANTAGE - On removal of a full cop by the doffer, the yarn is automatically severed at the point of re-commencement of spin.
