  • Patent number: 4194962
    Abstract: A system for sputter coating architectural glass is disclosed which includes an evacuable enclosure, a conveyor for moving glass to be coated along parallel paths, an elongated sputtering cathode supported between the paths, and structure by which ionizable gas is introduced into the enclosure. The cathode creates a continuous band of plasma extending about it through a region defining laterally spaced first and second sections extending generally parallel to glass on respective sides of the cathode and return sections joining the ends of the laterally spaced sections. The cathode includes sputtering material target face portions extending adjacent and parallel to the plasma sections and a magnetic field directing system for constraining the plasma flow in the sections to extend substantially uniformly over the target face portions.

  • Patent number: 4078839
    Abstract: A lifting and carrying device for flower pots is formed by a generally vertical main support post or bar with a pot supporting member at its lower end and a pair of gripping jaws actuated by a lifting and carrying handle pivotally secured to the upper end of the post. The jaw mechanism is formed by a fixed jaw on the post for engaging the upper rim of the pot on the outside surface and an inner jaw swingably mounted on the post and actuated by a linkage mechanism connected to the handle for engaging the upper rim of the pot on the inside surface. As the handle is lifted, the jaws grip the upper rim of the pot and the pot is lifted for carrying.
