Title: Biological dephosphatization and (de)nitrification.
Inventor: LORENZ GUENTER
IPC: C02F1/24
Filed: 1988-02-26
Abstract: Process for purifying sewage water in technical sewage water purification plants, to improve degradation and the biological removal of phosphate and of nitrogen, whilst at the same time optimizing the energy balance and the required volume of construction, by increasing the efficiency of the stages of treatment. Before passing through an inlet (27), the sewage water passes through at least one aerobic area and at least one nitrifying zone (2, 3, 4, 5). At least one pretreatment inlet area or balancing area (1) or an unused empty buffer zone is activated biologically. This occurs by means of the introduction of a biological treated mixture of sewage and sludge containing nitric bacteria and oxygen, preferably from the final sedimentation area (6) into the inlet area, this occuring at least before the preliminary sedimentation (9) or, should there be none, before the sludge activation (2, 3, 4, 5), after possible intercalation of phosphate redissolution sections (20) appropriate to the process.

Abstract: The idling rotational speed of an internal combustion engine is controlled proportionately to the value of a control valve command (Icmd) obtained on the basis of the sum of a feedback control term (Ifb) and an additional correction term conforming to the external load of said internal combustion engine, thereby obtaining said additional correction term as a function of a parameter depending upon the deviation of intake manifold pressures (Pba) between no-loaded and loaded conditions of said external load. A learnt value(Pbref) is calculated based on an intake manifold(33) pressure when said internal combustion engine is in idling condition, the control valve(30) is under feedback control, and said internal combustion engine is in a no-load state. When said internal combustion engine is in a loaded state, an existing manifold pressure is detected and the addition correction term(Iat) is calculated based on an difference between the learnt value and the detected manifold pressure.

Abstract: The folded box (1) has a bottom wall (2), which is connected at its edges to side wall portions (3 to 6) which can be swivelled up about joint or folding lines (11) and are connected on at least one side of the folded box (1) at their mutually facing edges (12) via joint or folding lines (13) by tabs (14) which are folded in the manner of a gusset in each case about a diagonal folding line (15), extending in the associated corner of the bottom wall. The box is to be designed in such a way that the connection of at least one side wall portion (3, 5) to the adjacent side wall portions (4, 6) is detachable without detaching a special connection means. This is achieved in that at least two slots (23) or pockets are arranged adjacently in or on two opposite side wall portions (3, 5), into which slots or pockets the free ends (24) of the folded tabs (14) can be inserted. <IMAGE>

Abstract: Plate-type radiators are provided with convectors (2) to optimise their specific heat output. The thermally advantageous fitting of the convector block, which is as a rule folded, to the front side, facing an observer, of a plate-type radiator necessitates an additional trim surface (30). The latter can only be fitted with difficulty from a production engineering point of view. The plate-type radiator according to the invention has, on the front side, a convector (2) to which the trim surface (30) is bonded. The bonding is advantageously carried out with an adhesive (9) having good thermal conductivity so that the trim surface also contributes to the heat output. In addition, it is particularly advantageous that further trim components can be fitted to the trim surface to conceal the top and side surfaces. As a result, a complete trimming of the plate-type radiator can be achieved in one operation. In addition, very compact plate-type radiators can be produced. <IMAGE>

Abstract: A mattress (10) having a core of pocketed springs is described, which consists of a multiplicity of springs arranged successively which are welded individually into pockets (16) and the pockets are connected to each other in the manner of a row via welded seams (18), a plurality of these rows (12a, 12b, 12c, 12d, 12e) being arranged adjacently to form the mattress and being connected to each other at contact points. The object is to carry out the manufacture of the mattress in a simple and inexpensive form, the intention being to avoid tearing of the pockets even under increased loading of the mattress. For this purpose, provision is made for the connection (22) at the contact points of the individual rows to consist of a loop component having a multiplicity of loops, in which, starting from the opposite row, a shaft component having a multiplicity of hooked heads arranged on shafts engages. In this manner, a permanent connection, which can withstand extreme loading, is provided in the region of the contact points of the individual rows in the manner of a press-on closure. <IMAGE>

Cette couche superficielle de protection est composée d'un matériau qui, dans les conditions de fonctionnement de la cellule: a) n'est pas sensiblement réduit par le produit métallique; b) ne réagit pas de manière sensible avec l'électrolyte contenu dans la cellule et ne forme par conséquent aucun matériau susceptible de réagir avec le produit métallique; et c) présente un potentiel électrochimique plus électronégatif que le potentiel électrochimique du composé que l'on soumet à l'électrolyse afin d'obtenir le produit métallique (46) dans la cellule. On peut former la couche superficielle de protection sur une couche métallique qui sert d'électrode et qui est composée d'un matériau dont l'oxyde satisfait lui aussi les critères de sélection de la couche de protection. Le matériau dont se compose la couche de protection peut également être appliqué sur la surface du revêtement de la cellule.

Abstract: Aromatic halide is converted to aromatic nitrile, e.g., p-chlorobenzotrifluoride is converted to 4-(trifluoromethyl)benzonitrile, utilizing Ni(Pφ₃)₃ as a catalyst where said catalyst is formed starting with NiCl₂ or NiCl₂·6H₂O where formation of said catalyst starting with NiCl₂ or NiCl₂·6H₂O and conversion of halide to nitrile are carried out in a single reactor vessel. The method comprises the steps of (a) forming catalyst by steps comprising (i) forming essentially dry Ni(Pφ₃)Cl₂  in situ  in said reactor vessel starting with NiCl₂ or NiCl₂·6H₂O, (ii) reacting said essentially dry Ni(Pφ₃)₂Cl₂ with Pφ₃ in the presence of a reducing metal in C₂-C₅ alcohol or aprotic polar reaction solvent in said reactor vessel to produce Ni(Pφ₃)₃ catalyst therein, and (b) adding said halide into said reactor vessel to form a complex in C₂-C₅ alcohol or aprotic polar reaction solvent from said halide and said catalyst and adding alkali metal cyanide to convert halogen to CN and thereby produce nitrile. When anhydrous NiCl₂ is a starting material, steps (a)(i) and (a)(ii) are preferably carried out as a single step where anhydrous NiCl₂ and at least three equivalents of Pφ₃ are added to C₂-C₅ alcohol or aprotic polar solvent followed by addition of reducing metal powder and reaction is carried out to convert NiCl₂ to Ni(Pφ₃)₃ with intermediate formation of Ni(Pφ₃)₂Cl₂. When NiCl₂·6H₂O is a starting material, essentially dry Ni(Pφ₃)₂Cl₂ is formed in   step (a)(i) by forming an admixture thereof with azeotrope-forming liquid (e.g., anhydrous C₂-C₅ alcohol or aprotic polar solvent or toluene) and heating to distill off water and forming essentially dry NiCl₂ which is converted to essentially dry Ni(Pφ₃)₂Cl₂ or the NiCl₂·6H₂O is reacted with Pφ₃ to form wet Ni(Pφ₃)₂Cl₂ which is dried by forming an azeotropic mixture and distilling to remove water or by heating or the NiCl₂·6H₂O is made essentially dry by heating with or without Pφ₃ present in the absence of reaction solvent to flash off water and form essentially dry NiCl₂ which is reacted with Pφ₃. The preferred C₂-C₅ alcohol is t-butanol which minimizes formation of hydrodehalogenation side-product in step (b) compared to other alcohols. The preferred aprotic polar solvent is acetonitrile.
