  • Watermelon seed remover
    Patent number: 5313707
    Abstract: A suitably dimensioned, hollow, crescent-shaped die with an upstanding handle provides a culinary tool for conveniently and quickly removing all the seeds from a watermelon. Upright side walls on the perimeter of the die engage each of the seed-bearing, crescent-shaped-in-section columns and extract the column as the die is withdrawn at the conclusion of the cutting portion of the cycle. By arranging a portion of the die and side walls in an overlapping relation, the areal extent of the die can be expanded, after withdrawal, to allow the attendant seed-bearing column to drop from the die by gravity. If desired, the overlapping portion can be augmented by slots and a pair of retainer pins to restrict the extent of change of the die area to a predetermined range; and inward shark tooth projections on the side walls can be used to enhance the ability of the side walls to lift the column during die withdrawal.

  • Golf training device
    Patent number: 5230512
    Abstract: In order to help a golfer to develop "muscle memory" for consistently executing an ideal swing, there is provided a grid plate on which is defined a ball contact zone. Enabling the golfer to see the head of the club as it is swung through the contact zone is a battery-powered L.E.D. mounted on a Velcro-fitted wrap-around jacket. By installing the jacket on the club head and illuminating the L.E.D., instantaneous visual feedback is provided so that aberrations from the ideal path defined by the ball contact zone are detected, interpreted and can immediately be corrected in subsequent swings. Both the jacket and the grid plate possess special features helping to protect against the harmful results of forceful, inadvertent impact between the clubhead and the grid plate.
