The fluidized bed reactor for biological treatment of effluent essentially comprises a container (1) over the base 2 of which elongated gassing units having gas exit apertures (5) are arranged parallel to one another, in such a way that in each case two neighboring circulating currents (8, 9) in mirror-image symmetry are produced in the reactor. In addition, the reactor (1) is supplied with a rete...

The illusion of distinct sound sources distributed throughout the three-dimensional space containing the listener is possible using only conventional stereo playback equipment by processing monaural sound signals prior to playback on two spaced-apart transducers. A plurality of such processed signals corresponding to different sound source positions may be mixed using conventional techniques witho...

Stable aqueous detergent gels wholly or predominantly in hexagonal liquid crystal form contain a principal non-ethoxylated non-soap anionic surfactant in which the head group is positioned terminally or next-to-terminally on a hydrocarbon chain, for example, a primary alkyl sulphate or an alpha-olefin sulphonate, together with either an auxiliary surfactant or a specified additive.

Installation comprising a reservoir crucible 11, 12 for molten cast-iron F with step-by-step extraction of a pipe T produced from the crucible comprising a cooled die. To obtain a cast-iron pipe of uniform thickness over its entire circular periphery, despite the absence of a core, the molten cast-iron F is set in slow rotation in the crucible by the tangential supply of molten cast-iron with a lo...

A method for displaying images in each of plural adjacent areas on a display screen (10) having a plurality of display rows uses stored boundary data to freely define a boundary between adjacent areas in row direction and to switch the image display upon crossing the boundary. In a system for implementing the method, the images to be displayed are stored in an image information storage (20), which...
