Inventor: BRAUN ALBERT
IPC: C21C7/064
Filed: 1980-12-15
Abstract: The present invention relates to a process for the manufacture of desulfurizing agents containing 1-6% by weight of chemically bonded water, based on calcium oxide-containing calcium carbide, for crude iron and steel melts. To this end, a molten mixture of calcium carbide and calcium oxide with a CaO content of 20 to 80% by weight is produced, which is allowed to solidify into a block. Next, the block which still has an average temperature of more than 400 DEG C., is rough-crushed to particles with a size of less than 150 mm and calcium oxide is added to the comminuted mixture, which still has a temperature of at least 400 DEG  C., in accordance with the CaO content desired in the end product. The mixture is finally ground in the presence of air or nitrogen with a moisture content of from 5 to 20 g/m3 (at 1.013 bar and 273.15 K) at temperatures below 100 DEG  C. to particles with a size of less than 10 mm.

Abstract: A liquid-liquid solvent extraction system comprises a mixing stage which includes a mixing device (10) for creating a dispersion of the two liquid phases followed by a residence chamber (14) designed to enhance contacting and mass transfer between the solute and solvent phases. The separating stage includes a drop size conditioning device (15) which establishes a drop size in the discontinuous liquid phase of the dispersion which can be easily separated from the continuous liquid phase in the succeeding settling device (16). The conditioning device (15) also acts to reduce entrainment of the solvent phase in the solute phase during separation of the phases. The settling device (16) may contain a series of baffles to reduce the time required for phase separation and to reduce entrainment of the solvent phase in the solute phase. 
     The system is used to extract metal ions such as uranium, copper, cobalt, nickel, and vanadium from aqueous process streams containing dilute concentrations of such ions. Hydrocarbon solvents which are partially or totally immiscible in water are used to extract the metal ions and may contain additives such as complexforming agents to aid in the mass transfer of metal ions to the solvent phase. After contacting and separation of the phases, the metal ions are recovered from the hydrocarbon solvent.

Abstract: This machine, which is intended for sharpening milling cutters or any other cutting tool, is composed of a fixed console (10) in the form of a plate, of two crossed carriages (7-8) and of a height- adjustable vertical column (4) carrying a grinding-wheel-holding spindle. In order to reduce the physical fatigue of the operator which results from having to lean forwards towards the working zone in order to reduce the distance between his eye and the working zone, and in order to enable him to work equally well standing up or sitting down and under good conditions, whether he be right-handed or left-handed, handicapped or non-handicapped, the bearing (9) for the articulation of the transverse carriage (7) is arranged in front of and overhanging the frame (2), whilst, on the one hand, the control table (20) is articulated at the free end of a lever (19) which is itself articulated beneath the plate and, on the other hand, the upper plane (22) of the longitudinal carriage (8) is situated at a distance from the ground which lies between 1 and 1.2 metres so that the working zone has a height which means that the operator does not have to lean forwards in order to adjust or check the sharpening operation. <IMAGE>

Abstract: Procede et appareil de controle automatique a haute vitesse d'informations enregistrees sur une bande magnetique video (30) pour determiner si l'enregistrement original a ete altere par effacement ou si un surenregistrement a ete ajoute a une partie non enregistree de la bande. Pour faciliter le controle, un signal basse frequence est ajoute sur la piste audio de la bande (30) au moment ou l'enregistrement original est effectue. Le controle consiste a detecter la piste de commande video de la bande (30) et la piste audio contenant le signal basse frequence ajoutee tout en rembobinant la bande a haute vitesse, Pendant le rembobinage, un detecteur (32) positionne sur la face arriere ou sans revetement oxyde de la bande (30) recoit des signaux provenant a la fois de la piste de commande video et de la piste audio. Les signaux detectes sont traites par un circuit de detection d'erreurs (22) ou ils sont analyses pour determiner la vitesse de la bande, l'amplitude d'impulsion de la piste de commande, l'amplitude des signaux audio, la configuration des impulsions de la piste de commande, et la configuration des signaux audio basse frequence. Une bande (30) sans defaut est indiquee par l'absence ou la presence simultanee du signal ajoute basse frequence de la piste audio et du signal de la piste de commande video. Lorsque seul l'un des deux signaux apparait, cela indique un defaut dans la bande (30) et sa position est stockee par un ordinateur (24) A la fin du controle, l'ordinateur (24) donne sur une sortie d'ordinateur (26) le nombre, le ou les types (s) et position (s) du ou des defaut (s).
