  • Patent number: 5425198
    Abstract: A device for automatically watering potted type plants has a shallow reservoir base/tray capable of holding water and also capable of supporting at least one previously potted plant and also capable of supporting an inverted container (such as a typical screw top jar turned upside down) for containing additional water (and/or other plant nutrients). A specially adapted support base is used to keep the bottom of the inverted container (where the opening is located) slightly above the bottom of the base/tray. The base/tray can have ribs or rails to keep the potted plant raised slightly above the lowest part of the tray (but lower than the opening in the inverted container). The water container has a detachable lid with a hole.

  • Patent number: 4195530
    Abstract: An ultrasonic flaw detector for detecting irregularities in an object, such as a pipe, having a segment of annular cross-section. The detector includes a transducer with an involute transmitting surface for sending ultrasonic signals into the object at equal non-radial angles of incidence. The detector further includes transmission apparatus for maintaining a constant physical relationship between the transducer and the pipe and interpretive apparatus for correlating reflections of ultrasonic signals within the object with irregularities.
