Abstract: L'invention a pour objet un procédé d'obtention de catalyseurs électrochimiques du type constitué par un film mince d'un métal noble, d'argent, de nickel ou d'un de leurs alliages déposé sur un support de graphite pyrolitique.  Ce procédé est caractérisé en ce que l'on effectue électrolytiquement le dépôt de ce métal sur le support de graphite pyrolitique dans une cellule électrochimique, à partir d'une solution aqueuse contenant un sel complexe dudit métal.  Les catalyseurs électrochimiques obtenus, et en particulier le catalyseur constitué par un film d'argent déposé électrolytiquement sur du graphite pyrolitique, montrent une très forte activité électrocatalytique pour la réduction de l'oxygène en solution aqueuse.

Abstract: AUTOMATIC CAPACITOR WINDING MACHINE            Abstract of the Disclosure An automatic capacitor winding machine has a retract-able bifurcated arbor and vertically movable clamps to grasp the ends of the capacitor dielectric layers and carry those ends to a point below the retracted arbor.  The bifurcated arbor is registered in its retracted state with its slot parallel to the dielectric layers.  The arbor is then extended and grasps the dielectric layers between its tangs.  The pressure grasping the dielectric layers is partially removed to allow the arbor to rotate and pull the dielectric layers from between the clamps.          A stripper washer is provided to freely rotate on the arbor with limited movement parallel to the axis of the arbor and with a relatively small clearance between the washer's inside surface and the arbor's outside surface.  Photoelectric means are pro-vided to accurately detect the location of the first tab (ter-minal) to time the insertion of the other tabs.  A reciprocating blade severs the dielectric layers after the capacitor is wound.        Further, a roller wets the outer surface of the capacitor to prevent its unraveling.  As the arbor is retracted, the wound capacitor bears against the stripper washer and is stripped from the arbor.

Abstract: ABSTRACT OF THE DISCLOSURE    An adjustable drop nipple is disclosed for connecting a fire extinguishing sprinkler at the underside of a room ceiling with a nipple in water distirbuting piping above the room ceiling. The adjustable drop nipple has a sealing coupling engaging said nipple and an elongated sleeve on the exterior of said sealing coupling extends toward said distributing piping and partially overlies the nipple, a tube is telescopically positioned in the sealing coupling and nipple and extends outwardly of the end of said sealing coupling opposite said nipple, a tapered surface is formed in said sealing coupling and a rotatable lock nut on the sealing coupling through which said tube extends encloses a split ring movable toward and away from said tapered surface upon rotation of said rotatable lock nut, the split ring is arranged for wedging action between said tube and said tapered surface of said coupling.  A resilient seal in the sealing coupling engages the tube.  This invention distinguishes from other inventions by reason of the arrangement of the telescopic tube within the sealing coupling which prevents the tube moving upwardly into blocking position in the distributing piping, also the tapered surface on the sealing coupling is positioned to receive the split ring and thereby lock the respective parts mechanically separately from the sealing coupling.  The present invention may therefore be adjusted lengthwise while containing water without leakage or the heretofore necessity of drawing the distributing piping.

These lugs project from the edge of the cast product and lie in the casting plane, but they have a partial thickness as compared with the thickness of the product.          Continuous wide slabs of unrefined copper or other electro-lytically refinable metal having partial thickness lugs on both edges can be cut to form electrode plates for subsequent refining by suspending in an electrolytic bath.   These partial thickness lugs serve as supports and provide elec-trical connection from the side rails of the electrolytic cell.  Their partial thickness conserves metal and weight.          In the continuous casting method and apparatus the revolving edge dams include special dam blocks defining partial thick-ness mold pockets for casting the integral lugs.  Synchroni-zation of lug positions along opposite edges of the cast product is maintained by controllably changing the relative temperatures of the revolving edge dams with respect to each other, for example, by relatively increasing the cooling of one of the revolving edge dams when it tends to lag the other, thereby relatively decreasing its length and increas-ing its rate of revolving, or, for example, by relatively decreasing the cooling of one when it tends to lead the other, thereby relatively increasing its length and decreas-ing its rate of revolving.
