Abstract: L'acide sulphurique rejeté lors de la fabrication de dioxyde de ttitane est concentré par évaporation jusqu'à une concentration comprise entre 65 et 70 %. Par un processus de maturation durant plusieurs jours, les métaux dissous dans l'acide se précipitent en règle générale en quantité suffisante, à l'exception du chrome et du vanadium. Afin d'en extraire également le chrome en quantité suffisante et en un temps suffisamment court, on ajoute à l'acide sulphurique concentré par évaporation une quantité d'aluminium d'un ordre de grandeur autour de 0,3 % en poids, ledit aluminium ayant une surface active et étant obtenu par enlèvement de copeaux, par fragmentation ou par pulvérisation juste avant d'être ajouté à l'acide sulphurique. Grâce au potentiel redox fortement négatif de cet aluminium actif, on obtient évidemment un chrome d'ordre inférieur dont les sels sont moins solubles que ceux du chrome d'ordre supérieur, ou chrome métallique, et qui se précipite plus facilement.

Abstract: A power converter embodying the principles of the invention, and having a positive and negative output utilizes a single magnetic amplifier controller to control two saturable inductor cores utilized to regulate the positive and negative outputs by modulating the positive and negative pulse output of the power converter transformer. The magnetic amplifier controller monitors and sums the two voltage outputs and derives an offset from average representative output signal. This offset from average representative output signal is compared with a reference signal to derive an error signal. A current responsive to the error signal is generated and utilized to periodically reset the two saturable inductor cores and regulate the positive and negative output voltages.

Abstract: The invention relates to a method and an apparatus for cultivating animal cells. Cultures of animal cells stable for a long time are accomplished by calculating the ratio (L/G) of the amount of lactic acid formed by the cultivation of the animal cells to the amount of glucose consumed thereby, within a predetermined time period de­termining the growth conditions of the animal cells there­from and thus controlling the cultivation conditions. When the ratio L/G, which is preferably from greater than 0 to 0.6, is outside the desired range, the dissolved oxygen concentration and/or the glucose concentration in the culture medium may be controlled by increasing the dis­solved oxygen concentration in the culture medium and/or decreasing the glucose concentration therein.

Abstract: A pressure-indicating device (14) for medical equipment, such as, for example, a vacuum suction flask (10), has a measuring tube (22) filled with a liquid (30, 32) as well as a closed end and an open end connected to the interior of the vacuum suction flask (10). A predetermined quantity of a gas (34) is present between the closed end of the measuring tube (22) and the liquid (30, 32). This pressure-indicating device is distinguished by the fact that a restriction point (28) is present in the area of the tubular passage of this measuring tube in such a way that the liquid (30, 32) can be displaced only very slowly inside the measuring tube when the pressure inside the vacuum suction flask is changing. A method of producing the measuring tube is described. <IMAGE>

Adjusting arms (10) articulated to the collecting casing (1) and associated with a screw (11) offer the possibility of varying the working angle of the machine positively or negatively. Shock mountings (9) associated with the receiver basket (3) provide the homogeneity of the unit.

Abstract: In order to improve the shifting characteristics of an electrohydraulically controlled, automatically shifting transmission particularly during cornering and braking, the driving speed (v), the lateral acceleration (aq), and the time variation of the throttle valve position are sensed in addition to the throttle valve position (alpha) and the engine rotational speed (nmot). From the time variation of the throttle valve position, a signal can be derived for the prevention of an upshifting operation since a motor vehicle driver's foot moves away faster from the accelerator pedal when approaching a bend in the road than would be the case for the normal deceleration of the motor vehicle.

Abstract: In an electrical control device, two printed-circuit boards which are located parallel, one on top of the other, are used in the casing, which printed-circuit boards are connected to one another at points and, on their board edge, support coupling parts which come to rest in a front wall of the casing after assembly. In order to develop a compact control device which can be assembled quickly and dismantled again, it is proposed that both boards be fitted with dedicated coupling parts, as a result of which two independent assemblies are produced. The one assembly also comprises a front wall, which is constructed integrally with the coupling parts, of the subsequent casing and a window-like opening provided therein adjacent to the coupling parts. The two assemblies are joined together via a reducing movement to form a structural unit, where the coupling parts of the one assembly close the opening in the front wall of the other assembly. The resulting separating joint between these mutually abutting coupling parts has connected in front of it a collar with a ring seal. In addition, the printed-circuit boards have contact pins and contact holders between them, which engage with one another during the reducing movement. <IMAGE>
