    Abstract: Direct fluorination of uracil and its derivatives, in the presence of an aqueous solvent, by fluorine gas to produce 5-fluorouracil and 5-fluorouracil derivatives is disclosed. Novel compounds produced by the reaction, such as 5,5-difluoro-6-hydroxy-5,6-dihydrouracil are also disclosed. The derivatives of 5-fluorouracil are useful as germicidal agents while 5-fluorouracil itself is a known cancer chemotherapy agent.

  • Hand and sewing machine needle threader
    Patent number: 3968761
    Abstract: A sewing needle threader using the presser foot of a sewing machine as a housing is disclosed. A movable rod is slidably mounted in the housing and contains a tiny hook adapted for insertion through the eye of a needle on one end of the rod. A spring is coiled around the rod and confined between defining walls of a chamber of the housing into which the other end of the rod projects. The rod is adapted to attach to a pivotally mounted handle located outside of housing. The handle may be placed in a raised position when not in use and may be lowered into alignment with the rod for advancing the hook through the front of the housing into engagement with the eye of a needle. In another embodiment the housing is adapted for use in threading hand held needles.
