Abstract: Benzene phosphonic dihalide is produced by oxygenation of phenyl phosphonous dihalide according to the following reaction:
     wherein X is Cl or Br. 
     The reaction is conducted at a temperature from about 0°C to about 200°C. Charcoal is added to the reaction mixture when impure phenyl phosphonous dihalide is used as a starting material. The product has high purity and is stable at high temperatures. It can be used as an intermediate to prepare flame retardants, insecticides, pesticides and plasticisers.

Abstract: Die Erfindung bezieht sich auf ein Verfahren zur Messung des Pegelstandes von flüssigem Metall in einerKokille, insbesondere in einer Stranggiesskokille. 
     Es ist bekannt, dass durch Aenderungen der einen Leiter durchsetzenden magnetischen Felder im Leiter Ströme induziert werden, und dass aus den Sekundärfeldern dieser Ströme auf die Anwesenheit des Leiters geschlossen werden kann. Doch versagen solche Messmethoden beim Stranggiessen von Stahl, da die gut leitende Kupferkokille die Felder so stark abschirmt, dass die Empfindlichkeit der Messeinrichtung nicht befriedigen kann. 
     Erfindungsgemäss wird nun der Einfluss der Kokille (K) ausgeschaltet, indem zwei Sekundärspulen (S1 und S2) verwendet werden, die koaxial und symmetrisch zur felderzeugenden Primärspule (P1) liegen und elektrisch gegeneinander geschaltet sind, so dass nur die Asymmetrie in der Anordnung des flüssigen Leiters zu den Spulen eine induzierte Spannung hervorruft. 
     Befindet sich kein Metall in der Kokille (K), so ist die Gesamtsekundärspannung gleich Null. SteigtderBadspiegel (B), so werden bevorzugt in der unteren Spule Spannungen induziert, so dass die resultierende Spannung ansteigt. Bei maximaler Asymmetrie, also wenn sich der Badspiegel (B) zwischen den Sekundärspulen (S1 und S2) befindet, wird auch ein Maximum der Gesamtsekundärspannung erzielt. Steigt der Badspiegel weiter an, so verschwinden Asymmetrie und Gesamtsekundärspannung wieder.

Abstract: In a process for digesting sludge from a biological waste water treatment plant, optimisation of the metabolic activities of the microorganisms involved in the reaction is achieved when some of the sludge is taken out of the reaction system (42, 43) by branching (21), partially dewatered with the aid of an artificial gravity field (22) and returned to the reaction system (23). The dewatering is preferably effected immediately before the mixing with fresh sludge and at accelerations between 450 and 650 g and also in the course of residence times of below 60 sec. <IMAGE>

Abstract: Un circuit de vieillissement accelere d'une memoire a circuit integre recoit un signal a deux etapes a une borne de vieillissement accelere (168). Un signal d'horloge de regeneration est fourni a une borne de regeneration (170) qui commande un compteur de regeneration (192). Une sequence d'adresses est produite par le compteur de regeneration (192) et envoyee au decodeur de rangees (194) et au decodeur de colonnes (196). Lorsque la commande envoyee a la borne (168) se trouve dans un premier etat, les amplificateurs de detection (132) a l'interieur d'un reseau de memoire (107) sont invalides de maniere telle que les circuits d'elevation (148) elevent les lignes de chiffres (116, 118) a un niveau eleve de tension. Le niveau eleve de tension est transfere dans des condensateurs de stockage de la cellule de memoire (120, 122). Lorsque la commande se trouve soit dans le premier soit dans le deuxieme etat, le signal de regeneration force un generateur de chaine d'horloge de rangee (176) a produire des signaux d'horloge de rangee et un generateur de chaine d'horloge de colonne (178) a produire des signaux d'horloge de colonne. Les adresses produites par le compteur de regeneration avec les signaux produits par les generateurs d'horloge de rangee et de colonne produisent le vieillissement des cellules de memoire (120), de l'amplificateur de detection (132) et des circuits associes a l'interieur du reseau de memoire (107). Le reseau de memoire (107) peut etre teste avec des signaux recus uniquement par l'intermediaire de quatre bornes afin de rendre possible le test simultane d'une pluralite de circuits integres sur une bande ne possedant pas de croisement de lignes conductrices.
