    • Electrically controllable optical element made of an optically isotropic liquid, in particular lens, and method for the production thereof on the basis of liquid composites. The prior art has disclosed apparatuses with various configurations using the electro-optic Kerr effect, in particular for modulating light. For a broad industrial application, the very strong temperature dependence of the effect in conjunction with high operating voltages is disadvantageous. In order to configure or produce an electrically controllable optical element in such a way that, on the basis of the electro-optic Kerr effect, a low threshold and operating voltage, a minimized temperature dependence of the effect and a low response time are achieved, the Kerr liquid (K) according to the invention – proceeding from an electrically controllable optical element as per the preamble of patent claim 1 – comprises a mixture of rod-shaped molecules (5) and non-rod-shaped molecules (4) as active composites and the Kerr liquid (K) forms a thin film with an impressable, wide-mesh, anisotropic network (9) between structured and/or planar conductive layers (2) applied to a substrate (1) in a thin-film cell in such a way that, in accordance with the electro-optic Kerr effect, the state of the active composites (4, 5) of the Kerr liquid (K) is isotropic without an electric field in the working temperature region RT and a change in the voltage-induced phase deviation or refractive index deviation of the optical element is produced by an electrically continuous adjustment of the voltage U or by switching the voltage U on/off and the light passes through an electrode interstice perpendicular to the electrodes. The invention lies in the field of electrically controllable optical elements.

    • The invention relates to a continually functioning sedimentation filtration installation for cleaning polluted process liquid such as coolant, hydroforming water, drilling, rolling, grinding emulsions and emulsions involved in rotational operations, wash water or similar. The installation consists of a sedimentation container comprising numerous parallel plate-type filter lamellae, arranged at an incline at a distance from one another to form a filter body, an evacuation device for the settled sediment, a supply line that opens into the sedimentation container for delivering polluted process liquid and a clean tank that is connected to an overflow of the sedimentation container for holding the cleaned process liquid. The installation is characterised in that at least two pipe connections are provided on opposite sides of the container, said connections opening into the container next to or in front of the filter lamellae (3), in order to supply the process liquid to the sedimentation container (1), that a settling chamber (7), filled with liquid, is provided between the underside of the filter body (2) and the base of the sedimentation chamber (1), the height of said chamber measuring at least 1/5 of the height of the filter body (2) and that a flow guide plate, which forcibly guides the supplied process liquid into the settling chamber (7), is provided between the filter body and the pipe connections.

    • Bauteile bzw. Werkstücke aus geschweißten hochfesten Stählen (Zugfestig­keit größer als 500 N/mm²), die einer Schwingbeanspruchung unterliegen, haben den Nachteil, daß die Schwingfestigkeit im Bereich der Schweißnaht erheblich geringer ist als die Schwingfestigkeit des Grundwerkstoffs. Das gilt auch für solche hochfesten Stähle, bei denen die Schweißnaht­übergänge mittels der bekannten Wolfram-Inertgasmethode nachbehandelt worden sind. Gemäß der Erfindung kann die Nachbehandlung der Schweiß­nähte mittels örtlicher Energiezufuhr, vorzugsweise durch ein Inert­gas-Lichtbogenschweißen mittels Wolframelektrode, in der Weise erfolgen, daß das Werkstück mindestens auf die von der Stahlqualität abhängige Sättigungsvorwärmtemperatur vorgewärmt wird und dann die Schweißnahtzone mit einer bestimmten Streckenenergie (kJ/cm) nachbehandelt wird. Dabei wird erreicht, daß Schweißnaht und Grundwerkstoff eine übereinstimmende Dauerschwingfestigkeit erreichen. In Fig. 4 zeigt die von den Bezugs­zeichen 1 bis 7 umrandete Gesamt-Fläche die brauchbaren Bereiche der Stromstärke, der Streckenenergie und der Vorschubgeschwindigkeit der Elektrode.
      Für geschweißte Werkstücke bzw. Bauteile, die im Off-shore-Bereich ein­gesetzt werden und daher nicht an Luft, sondern auch im Meerwasser schwing­beansprucht sind, tritt zusätzlich die Gefahr der Spannungsrißkorrosion auf, die durch das Vorwärmen auf die Härtebegrenzungstemperatur ≦ Sätti­gungsvorwärmtemperatur vermieden werden kann.
