Patent EP-0404982-A1 (EP)
Inventor: MELLEM JOACHIM
IPC: D04H1/736
Filed: 1989-06-29
Abstract: In the continuous production of non-woven mineral wool, fibre/gas/air mixtures (3, 4) generated by a plurality of unravelling units (14 to 17) are directed, to form a wool lap (25), onto collecting conveyor units (19, 21) having curved suction surfaces (c, d) which are under suction pressure. The arrangement is such that each fibre/gas/air mixture formed by the individual unravelling units (14 to 17) is assigned an imaginary suction surface increasing in size in the conveying direction, specifically d c. It is thereby possible, in a space-saving design, with a constant suction pressure to produce on each collecting conveyor unit mineral-wool laps of rock wool with bulk densities even below 25 kg/m<3> of good product quality. Furthermore, multi-layered felt webs can be formed by connecting a plurality of units in series or by an oscillating deposition of an individual lap. <IMAGE>

Abstract: In an installation for burning hazardous waste, a combustion chamber (20) into which some of the hazardous waste, in particular in gaseous and liquid form, is injected by a burner (23) and in which it is burnt is inserted downstream of a rotary tubular furnace (1). The rotary tube (11) of the rotary tubular furnace (1) opens into the combustion chamber (20), which is constructed as a stationary tube, in the lower conically converging region (21). The flue gases produced in the rotary tubular furnace (1) flow upwards together with the flue gases produced in the combustion chamber (20). At the same time, secondary air is also fed in, as a result of which an extraordinarily good burn-up rate is achieved right up to the end of the combustion chamber. Since a part of the hazardous waste is burnt in the combustion chamber, the dimensions of the rotary tubular furnace (1) can be reduced.

Title: Ventillamelle
Inventor: HEGER WERNER
IPC: F04B39/10
Filed: 1989-12-12
Abstract: Eine bekannte Ventillamelle die entlang der Oberfläche eines Gehäuseteils bewegbar und an wenigstens einem Ende durch einen in einem Schlitz des Gehäuseteils geführten Mitnehmer angetrieben ist, bedarf zur Abdichtung des Gehäuseteils eines Flachschiebers. Dieser bringt als eigenes Bauteil einen erheblichen Aufwand mit sich. Zur Verringerung des Aufwands schlägt die Erfindung vor, die Ventillamelle (6) so auszubilden (Fortsätze 9, 14), daß sie den Schlitz (12) in jeder Bewegungsphase überdeckt. Die Erfindung eignet sich besonders zum Einsatz in dem Ansaugventilsystem eines Verdichters.

Abstract: Dehydrogenation of C₃-C₅ paraffins is integrated with conversion of the resulting olefins to ether to improve efficiency for ether production by directly charging all but the lightest components of the dehydrogenation zone effluent to the etherification zone. A particularly preferred arrangement of this invention uses an etherification zone for direct production of MTBE from the dehydrogenation zone effluent and two fractionation columns to yield an overhead stream of light ends (C₁ to C₃) and of oxygenates, a stream of recycle isoparaffins, recycle methanol, and a product stream of MTBE. The arrangement also simplifies the removal of undesired oxygen-containing compounds such as H₂O and DME from the recycle paraffin stream to the dehydrogenation step by allowing the use of only a depropanizer to remove both oxygenates and light ends without the additional cost of a separate oxygenate recovery unit.

Inventor: CROTTI PIER LUIGI
IPC: H01L21/3205
Filed: 1989-11-13
Abstract: Step coverage in contacts may be improved by forming a tapered hole through a dielectric layer by:
     a) plasma (RIE) etching through a "contact" mask the dielectric for a depth shorter than the thickness of the layer leaving a residual thickness of dielectric on the bottom of the etch;   b) removing the residual masking material;   c) conformally depositing a TEOS layer;   d) etching the conformally deposited TEOS layer without a mask in (RIE) plasma until exposing the underlying silicon or polysilicon with which the contact must be established.   
     The anisotropic etching of the TEOS layer, conformally deposited on the partially pre-etched dielectric layer, determines a "self-aligned" exposition of the underlying silicon or polysilicon and leaves a tapered TEOS residue on the vertical pre-etched hole's walls, thus providing a desired tapering of the contact hole. Photolithographic definition is no longer a critical factor. (Figures 1-4).

Abstract: On a mis au point une pièce d'outillage composite présentant une excellente stabilité dimensionnelle, pouvant être préparée à faible coût, et employant un système de résine époxyde à un constituant comportant un catalyseur lequel est le produit de réaction d'un dicyanate aromatique et d'un imidazole. On incorpore des matières de renforcement dans la matrice, puis on durcit le préimprégné ainsi obtenu à basse température en descendant jusqu'à la température ambiante, jusqu'à obtention de l'état final. Ensuite, si l'on cherche à obtenir des performances à température élevée, on peut post-durcir le produit à des températures élevées, sans qu'un gabarit à haute température ne soit nécessaire.

On accélère et intensifie ainsi l'échange de gaz dans les pores et dans les cavités internes des objets à désinfecter. On peut utiliser pour générer les rayonnements UV et l'ozone une unité mobile qui comprend deux montants (64) entre lesquels s'étendent plusieurs tubes de rayonnements UV (62), un agencement catalyseur tubulaire (60, 74, 76) et des barres de protection (66, 84).
