  • Patent number: 5735526
    Abstract: A method for the evaluation of the pattern of shot resulting from a single shotgun round for purposes of optimizing the selection of ammunition type and prediction of shot pattern, and a target for its implementation. The shooter fires a single round at the target. Then a rotating overlay allows the pattern of shot to be evaluated with respect to a center aim point and an overlay axis and kill zone. The overlay is rotated through a series of clockwise, then counterclockwise increments. At each increment, the target is scored with respect to the overlay. The number of shot striking the kill zone for each position of the overlay axis is computed and by observation the shooter can determine the optimal ammunition for use with the weapon and for a given type of game.

  • Patent number: 4677788
    Abstract: A support for tomato plants and the like to reinforce them while growing. It is preferably of plastic material having a bottle shape with an elongated neck. Such neck is progressively increased in diameter from the top to the base portion. At the points of increasing diameter, there is a shoulder serving as a stop for a slip-fitted neck portion. On the shoulder, is supported a wheel-like ring onto which the plants may be tied. Several such rings of increasing diameter of sleeve are provided. The neck instead may be progressively tapered downwardly and outwardly with the wheel-like rings held in place by the taper. Holes are provided at a distance above the bottom of the base portion to provide a reservoir of water for stabilizing the tube in the soil.
