Abstract: A biological waste water treatment is carried out in a single tank (A). The conditions in the tank are controlled to provide a biological reaction zone (S) containing waste water and biodegrading organisms and an overlying clarification zone (C) from which an effluent of treated waste water flows (46). The recycle stream is continuously withdrawn from the biological reaction zone, supplemented with influent waste water (43), passed through an oxygen-dissolving device (R), and the supplemented stream returned to the reaction zone (S). The oxygen is monitored and supplied (49, 51, 53, 55) to satisfy the demands of the organisms and, at the same time, to keep the oxygen in solution. According to the invention, the supplemented recycle stream is continuously injected along the bottom of the biological reaction zone (25) in a horizontal shallow inflow having a width substantially greater than its depth and a flow considerably greater than that of the influent. And, the recycle stream is withdrawn from near the bottom of the reaction zone (30, 31), at a vicinity remote from the inflow, in an outflow having a substantially greater width than its depth. In this way there is created between the inflow (25) and the outflow (30, 31) a horizontally relatively fast flowing undercurrent having an extensive uninterrupted interface with an overlying relatively quiescent body of mixed liquor flowing upwardly relatively slowly.

Abstract: Information is transmitted on one of the phase conductors of an a.c. line in a form of a series of short-duration pulselike amplitude reductions in the voltage during one and the same half cycle, whereat the pulses form a binary code word representing the information. These reductions are generated by means of a current transformator (14) in series in the phase-conductor (4). The secondary winding is short circuited by a transistor (15) controlled by a control unit (6) to be opened for a short duration for each desired pulse. When the transistor (15) is opened, a voltage regulator (17) connected across the secondary winding restricts the change in magnetic flux in the transformator core to a maximum value dependent upon the lenght of the impulse series. The current is held over a given miniumum value during a transmission by a current regulator (27) and by connecting a load (28) to the phase conductor (4).

Un tel dispositif est notamment necessaire quand, pendant la marche du vehicule, les lampes ou les glaces sont subitement salies ou que le lave-glace n'a plus d'eau. Les recipients connus de ce genre presentent l'inconvenient que l'ustensile est forme specialement et qu'il est place directement dans l'eau de reserve, laquelle est alors rapidement salie. Avec le recipient selon l'invention, de tels inconvenients et d'autres encore sont evites. Pour cela, il presente une deuxieme chambre (3), etanche aux liquides, formant reservoir d'eau et communiquant par une ouverture (1c), apte a etre obturee, avec la chambre de conservation (4a) de l'ustensible de lavage (5). Alors que, dans les dispositifs connus, l'eau en reserve est constamment en contact direct avec l'ustensile de lavage, dans le present recipient, ce contact est obtenu manuellement et de facon indirecte. Cela a en particulier pour avantage que l'eau en reserve reste propre.

Abstract: Procede et appareil de commande d'un moteur a induction a courant alternatif, ayant au moins deux phases. Le moteur est commande par deux signaux d'entree (S1, S2), qui sont connectes a un separateur (1), dont les signaux de sortie sont utilises pour engendrer des signaux d'alimentation separes aux phases du moteur. Lorsque ceci est effectue, un premier et un second signal (B1, B2), representant le champ magnetique dans le moteur, est envoye en retour sur le separateur (1) en vue de la modification des signaux d'alimentation (S1, S2). Une unite de mesure et de calcul (12) engendre les signaux representant le champ magnetique dans le moteur par reconstitution a partir des signaux de mesure et possede deux canaux de signaux pour la generation des signaux de champ magnetique au-dessus et au-dessous d'une frequence predeterminee (w), respectivement. Dans un premier canal un signal (E9) qui represente la tension d'aimantation est integre et envoye par l'intermediaire d'un filtre passe haut (24), l'integrateur et le filtre passe haut etant combines en un seul bloc, alors que dans l'autre canal un signal (I'o) qui represente le courant du stator est envoye par l'intermediaire d'un filtre passe bas (26). Les signaux provenant du filtre passe haut (24) et du filtre passe bas (26) sont connectes a un additionneur (25) et de la a une unite d'echelle (27), dont le signal de sortie est utilise en combinaison avec les signaux provenant des autres phases du moteur comme l'un desdits signaux representant le champ magnetique dans le moteur, apres transformation de coordonnees. Le signal (E') qui represente la tension d'aimantation est obtenu soit a partir d'un enroulement de mesure (20) dans le stator du moteur ou par mesure du courant du stator (Io) et de la tension d'alimentation (Vo) et par calcul selon la formule E = Vo-RsxIo, dans laquelle la constante Rs represente la resistance de l'enroulement du stator.

Abstract: For an internal combustion engine, an exhaust valve casing (11) is provided of the kind which provides a valve seat (12) and exhaust passage (11a), and supports at (14, 15) the exhaust valve (13), and a valve guide (17) therefor, separately from the cylinder head (16). The positive cooling around the peripheral wall (11f) around the exhaust passage as normally practiced in known constructions of exhaust valve casing is abolished. Thus, cooling chambers (11c, 12b) are provided only at two locations, that is, within a peripheral wall around the valve guide, and within a peripheral wall around the valve seat. 
     Such an arrangement ensures that thermal losses from the exhaust gases passing through the exhaust passage are kept to a minimum, thereby ensuring that more energy is available for use by a supercharger, exhaust gas economiser, or the like.

Abstract: In the method of pneumatic compacting of molding sand in molds with a molding cavity closed and delimited by the model, the cavity is first filled with sand and set under pressure at a pressure gradient comprised between 100 and 1000 bar/s. The absolute pressure before and after exposure to the pressure is comprised between 0.8 and 8 bars, so that exposure to pressure is effected within milliseconds. It is thereby possible to obtain a high and uniform mold hardness with minimum construction means and with a reduced energy and air supply. Alternatively, the sand introduced in the molding cavity may be exposed to a vacuum comprised between 0.4 and 0.2 bar, and then the free surface of the sand may be subjected to a compressed air jet up to 15 bars. The jet has a supersonic speed. A device for implementing this method comprises a molding cavity (1), a jet opening (7) and a closure (11) for that opening.
