    Abstract: A shaped metal container such as a can is uniformly electrocoated in an inverted position by the insertion of an electrically conducting nozzle therein through which coating material may flow into the interior of the container while an electrical potential is maintained between the container and the nozzle. The nozzle is shaped to direct flow of the material into the corners of the container as the nozzle is inserted and to maintain a transient bath type mode after the nozzle is inserted into the container. Coating material is delivered at a flow rate which permits the can to remain full in an inverted position. When the nozzle is removed the container empties without further mechanical operations.

    Abstract translation: 诸如罐的成形金属容器通过在其中插入导电喷嘴而在倒置的位置被均匀地电涂覆，通过该导电喷嘴，涂层材料可以流过容器的内部，同时在容器和喷嘴之间保持电位。 喷嘴被成形为当喷嘴插入时将材料的流动引向容器的角部，并且在喷嘴插入容器中之后保持瞬时浴型模式。 涂层材料以允许罐保持在倒置位置的流量被输送。 当喷嘴被移除时，容器没有进一步的机械操作而排空。

    Abstract: A collapsible alignment and back-up tool adapted to be inserted in abutting ends of pipes or tubular members to be joined together, as by welding and the like, for maintaining such abutting ends in proper alignment and providing a continuous back-up during the joining operation includes an assemblage that is collapsible when subjected to the influence of a magnetic field. Due to its magnetic structural characteristics, the tool may be caused to move longitudinally within a tubular member or it may be restrained at any location along the length of the tubular member. A pair of end plugs are slidably mounted on a shaft. The ends of a plurality of interengaging arcuate segments are supported on shoulders carried by each of the end plugs to form, in expanded condition, a substantially cylindrical surface that collapses when the end plugs are moved outwardly apart along the shaft. The end plugs are formed of a magnetic material and all other elements are formed of relatively nonmagnetic material. When subjected to the influence of a magnetic field, the end plugs are caused to move apart to collapse the tool and/or to move the tool longitudinally within a pipe or tubular member.

    Abstract: A fusion system is provided whereby material in comminuted form or the like may be automatically fused under conditions which provide a homogeneously fused sample which then may be analyzed by analytical techniques to determine content of the material. The apparatus for carrying out the fusion provides control of the initial heating time, fusion time, and cooling time, as well as controlling the mixing or blending of the sample material during the fusion to ensure the homogenuity of the mixture.
