Abstract: The storage and/or transport box 1, preferably made of plastic, is provided with a flat bottom 2, two side walls 3a and 3b and a front wall 4 and a rear wall 5. On the inside, the side walls 3a and 3b have retaining devices 6 for inserting partitions 8 which are essentially parallel to the front wall 4 and rear wall 5, and on which support or abutment surfaces are constructed which are effective in each case both parallel and transverse to the plane of the partitions. The retaining devices 6 consist of channel-shaped guide profiles 6 which extend in the vertical direction of the side walls 3a and 3b, are profiled so as to project outwards from the main plane of the side walls 3a and 3b, and whose maximum guide profile height ends at a distance above the bottom 2. <IMAGE>

Abstract: A sea water distillation device comprises a spiral coil sealed on both faces and composed of radially repetitive layers. Each layer consists of two microporous membranes (12) arranged on both faces of a hot concentrate spacer grid (11). Condensation films (13) arranged on the sides of the membranes (12) remote from the hot concentrate spacer grid (11) are connected to a coolant fluid spacer grid (14), and each condensation film (13) is connected to another condensation film (13). A further microporous membrane (12) is arranged on either side. The cold concentrate (K) is introduced from the exterior into the interior between the condensation films (13) which are maintained at a distance apart by the coolant fluid spacer grid (14). It then flows into a heating device and returns to the exterior in countercurrent between the adjacent hot concentrate spacer grids (11). The distillate (D) is evacuated radially. The spacer grids (11, 14) consist of crossed tubes (15, 16) arranged at an angle to the direction of flow (R).

Abstract: A magnetic resonance imaging method for high quality short echo time imaging is suggested using FID-acquired-echoes. Gradient recalled echoes are excited in two short echo time acquisition sequences having opposite reading gradients. Half-echoes for corresponding phase encoding steps are concatenated to reconstructed echoes. An image is reconstructed from the reconstructed echoes using a Fourier transform reconstruction method. With the method artefact free high quality images with echo times below 4 msec can be obtained, even under unfavorable conditions, such as fast blood flow.

Abstract: An additive process allowing discretionary interconnection of only the acceptable devices on a semiconductor wafer includes screen printing a polyimide layer over the wafer to form vias (52) over all of the device contact pads (50) on the wafer while coating the remainder of the wafer. The devices are then individually tested through the vias and, when a device (48) is determined to be unacceptable according to predetermined specifications, the vias above that device are blocked, e.g. by filling with polyimide. A layer of metal (60,62) is next deposited over the entire wafer and makes electrical contact with only the acceptable devices since the unacceptable devices have been blocked off. The metal layer is thereafter patterned to leave an interconnection pattern wherein only the acceptable devices on the wafer are electrically connected.

Abstract: In the treatment of solid residues containing heavy metals from combustion plants, the heavy-metal compounds dissolved after washing-out and subsequently precipitated are separated from the solvent, usually water or slightly acid aqueous solutions by cross-current diaphragm filtration. The sludge obtained during filtration and comprising precipitated insoluble heavy-metal compounds is dewatered together with the remaining solid residues and made suitable for dumping, e.g. by using binders. The cross-current diaphragm filter improves the washing of heavy metals out of the washing or waste water, and the method and the associated plant are simplified by the joint processing of the sludges containing solids.

Abstract: In the transmission of digital signals, the use of pulse stuffing methods is often required, for example to provide synchronisation. When the original signal is recovered, the timing of this signal is affected by waiting time jitter. A method and an arrangement to reduce waiting time jitter are described. A measurement of the mean filling state of the elastic memory (ES, ES') is determined in the synchroniser (Sy) and in the desynchroniser (Desy). This measurement is transmitted from the synchroniser (Sy) to the desynchroniser (Desy). In the latter, the measurements are compared in the comparator (V) and with the value obtained a PLL is controlled which recovers the original timing (tD).   <IMAGE>
