Abstract: An extraction method and a countercurrent liquid-liquid extraction column extracts a hydrogen peroxide containing oxidized working solution of an anthraquinone process. The extraction column includes a plurality of sieve trays, wherein at least one of said sieve trays is a valve sieve tray including a downcomer and at least one floating valve that includes a liftable opening member covering a valve hole in the valve sieve tray and can be lifted by the light phase below the sieve tray. A more stable operation of sieve tray extraction columns is possible by using a floating valve so that the flow rate of the oxidized working solution of an AO process and the daily production of hydrogen peroxide can be increased.

Abstract: The present invention relates to a method for producing a polyelectrolyte complex (PEC) membrane having a predetermined porosity via salt dilution induced phase separation, in which a liquid polymer solution (P) containing polyanions (A) and polycations (C) dissolved in an aqueous medium at an overcritical salt concentration is exposed to an aqueous medium.

Abstract: The invention relates to a lighting device which is operable in two modes. In a first operating mode the flux of a lighting effect having a specified chromaticity is rendered based on the maximum (luminous) flux at which the chromaticity can be rendered by the lighting device. This can cause the maximum (luminous) flux across a range of colors that the lighting device can render to vary greatly. For example, a white color may be rendered at a far greater intensity than a primary color. In a second operating mode the specified chromaticity is rendered based on a predetermined maximum (luminous) flux for that specified chromaticity, or a color range that it is comprised in, or a predetermined maximum (luminous) flux for one or more color channels that are used in combination to render the light effect. This reduces the differences in maximum (luminous) flux of lighting effects rendered across the range of colors that are rendered by the lighting device.

Abstract: In a wireless mesh network, a battery operated node can select a parent node via which messages are routed to further nodes. The parent node can initially be selected based on signal strength. The node receives acknowledgements for messages sent, if they arrive. The node calculates a reliability indicator of the parent node based on the number of messages for which an acknowledgement has been received. If the reliability indicator exceeds a predetermined threshold the node selects a new parent node, based on second selection criteria. For example, the node with the next greatest signal strength.

Abstract: A lighting system controller, a lighting system control method and software program product are provided for controlling a lighting device based on a trigger signal, such as a presence detection signal from a presence sensor. Instead of switching the lighting device to a fixed light setting at all times when the trigger signal is received, the initial light output of the lighting device is determined. The lighting device is then controlled according to a fixed light setting (e.g. white light at full brightness) if the determined initial light output is within a predetermined range, and else it is controlled according to a function relative to the determined initial light output. For example, if the lighting device is participating in a romantic scene emitting predominantly red light the lighting device may switch to reddish white light instead of the full white light and/or the brightness level of the light is lowered compared to the fixed light setting.
