Abstract: A zinc-bromine secondary battery having a recirculating electrolyte uses an array of cells (14,15,16) in series with a parallel fluid flow through the several cell spaces along the confronting electrodes. The intermediate electrodes (16) are bipolar with their cathode face (26C) having a coherent porous mass of binder-free charcoal particles of stable dimensions and configuration lightly pressed into electrical contact with it and with each other. Spacer means (26C) holds the particles off from contact with the confronting anode face. A single electrolyte flows through each cell with a flow path divided so that a high speed and throughput major portion bypasses the charcoal particles and a minor portion branches therethrough. The zinc-bromine molarity of the electrolyte is preferably 0.5-1.5 at full charge and 2 to 4 at deep discharge and preferably only about 1% by weight of the molecular bromine present is in circulation with the remainder trapped in the electrode assemblies at all times. The cell has a minimum long-term system degradation, has limited self-discharge and has low environmental hazards.

Abstract: A catalyst suitable for the catalysis of the oxidation of carbon monoxide is prepared by providing the substrate with tin (IV) oxide support material and with a catalytically active material.The tin (IV) oxide is provided by contacting the substrate with a dispersion of colloidal or non-colloidal particles in a liquid medium, said dispersion being convertible to tin (IV) oxide by drying and firing, followed by drying and firing. A catalyst can be so-produced having low flow resistance, high low temperature activity and relative insensitivity to deactivation by moisture. The dispersion may, for example, be a tin (IV) oxide aqua-sol made, for example, by peptising hydrated stannic oxide with a quarternary ammonium hydroxide.

Abstract: Un circuit discrimateur analogique à haute vitesse utilise un tube à rayons cathodiques (21) et comporte une pluralité d'éléments cibles (43, 45) disposés en cercle, et dont le faisceau à électrons balaie de façon répétée les éléments cibles disposés en cercle. L'amplitude du signal analogique destiné à être échantillonné est appliquée à une grille (41) du tube à rayons cathodiques afin de moduler l'intensité du faisceau d'électrons avant qu'il ne frappe les conducteurs. Les électrons qui frappent les élements cibles créent une tension détectable proportionnelle à l'amplitude de la tension analogique aux différents moments où le faisceau d'électrons frappe les différents éléments cibles. Cette sortie peut encore être codée numériquement par un ou plusieurs convertisseurs de signaux analogiques en signaux numériques.

Abstract: Une enceinte (110) définit un alésage central élargi (162) d'où fait saillie un raccord à conduits multiples (126). Un joint élastomère (128) relie de manière flexible l'extrémité interne du raccord à l'extrémité externe d'un siège coulissant respectif (116), l'extrémité interne du siège étant adaptée pour coulisser longitudinalement dans l'alésage central, de telle sorte que le joint élastomère soit soumis à une action de cisaillement lorsque le raccord est dévié de manière pivotante par rapport à l'enceinte. Un ou plusieurs disques de pistons (174, 176) s'étendent en travers de l'alésage central élargi de manière à définir une série de chambres individuelles de pression (182, 184, 186). Une pluralité de manchons cylindriques creux (188) s'étendent au travers des disques, l'intérieur de chaque manchon jouant le rôle d'un prolongement d'un conduit respectif au travers du connecteur. De préférence, pour des conduits "N", on aura N manchons et (N - 1) disques de pression définissant N chambres de pression, de manière à avoir pour chaque conduit une chambre de pression correspondante et une ouverture d'égalisation de pression individuelle (204) peut être aménagée entre l'intérieur de chaque chambre de pression et son manchon correspondant. Toute différence de pression entre deux chambres de pression aura tendance à forcer le disque de pression entre les deux chambres dans le sens de la pression différentielle, jusqu'à ce que le disque se trouve en contact avec l'extrémité éloignée de la chambre ayant la pression la plus basse. En conséquence, les forces de compression exercées sur les joints flexibles seront déterminées par la pression maximum présente. En outre, étant donné que les forces sont symétriques par rapport à l'axe longitudinal central du connecteur, le siège n'aura aucune tendance à se gripper lorsqu'il coulisse dans l'alésage central.

Abstract: A valve, especially a solenoid valve, with isolation of media and with a valve housing (1) in which there is arranged a valve chamber (2) which is connected to an inlet flow channel (3) and, via a valve seat (4), to an outlet flow channel (5). The operating element (7) is connected via a valve stem (11) to a valve plate (6). The section of the valve stem (11) projecting into the valve chamber (2) is surrounded by a hose piece (13a). The one end of the hose piece (13a) is connected fixedly and in a sealing manner to the valve stem (11), the other end being similarly connected to the valve housing (1). Between the hose piece (13a) and the valve stem (11) there is arranged a helical compression spring such that one end of the helical compression spring (14) is supported on the wall of the valve housing (1) and the other end is supported on the valve stem (11). Under the influence of the pressure of the medium, the hose piece (13a) is pressed in between the windings of the helical spring (14) and relieves the stress of the spring such that, in the event of an increased pressure of the medium the closing or opening pressure resulting from the medium pressure is at least partially compensated for by the relief of the stress on the helical compression spring. <IMAGE>

Abstract: A catheter placement device includes an adapter (26) with an elastomeric grommet (30) through which a pliable catheter (14) is fed into a blood vessel of a patient. The grommet (30) has a flange (66) engageable with the catheter (14) and effects a relatively low resistance to distal movement of the catheter (14) and a relatively high resistance to proximal movement of the catheter (14). A locking member (28) may be used with the adapter (26) to hold the catheter (14) against movement through the adapter (26). The adapter (26) and member (28) are relatively rotatable to squeeze the grommet (30) against the catheter (14). Retention members (60,62) may be used to prevent inadvertent separation of the adapter (26) and member (28) during relative rotation.
