Abstract: A method and apparatus for providing the sequential delivery and timed release of measured amounts of additives to the water supply of livestock or plants is disclosed. The invention uses a direct injection method to meter and deliver fresh and accurate dosages of additives to a supply of water through the use of a timing mechanism operably attached to a flow control valve.

Abstract: A multistage transmission line interconnect device (50) for joining two microstrip circuits (82, 86). A center conductor pin (52) extends through a cylindrical dielectric (54) to form a coaxial midsection of the device. The ends of the pin extend from the dielectric to form a conductor for a straight open troughline at each end of the device. The ends of the pin are connected to the microstrip circuits by ribbon bonds (80, 84). Because the midsection of the device is coaxial, the microstrip circuits (82, 86) may be oriented at arbitrary angles with respect to one another.
