  • Fuel-consumption monitor for diesel engine
    Patent number: 4338816
    Abstract: A fuel-feed line extends from a diesel-fuel tank to a fuel pump for a diesel engine and the upstream side of this fuel pump is connected via a return line back to the tank.

  • Decorative tie bow
    Patent number: 4339059
    Abstract: A tie bow of ribbon for gift packages and a process of fabricating the bow are disclosed. The bow is formed from three separate ribbon pieces and includes a looped base portion and a superposed wing portion which are united by a central tying strip. As disclosed in the bow-making process, the loop and wing are easily formed by shaping and crimping strips of single-ply ribbon and impaling them on a pair of spaced needles. The tying strip is then looped over the impaled ribbon pieces and stapled to itself to hold the strip in place and finish the bow.
