  • Patent number: 6050017
    Abstract: A flexible, self-supporting decoy for wild game which requires no wind to inflate and which maintains its shape even under heavy dew or rain showers. When used for birds, the decoy may comprise as few as three pieces, namely, a stake, a windsock-type body of flexible yet self-supporting material, and a fastener. The body may be rotatably supported about a stake by the simple expedient of an opening in the lower portion of the body large enough to pass over the stake and a second opening in the upper portion too small to pass over the stake but large enough to receive a fastener with a head or flange large enough to secure the body. Such decoys may be quickly collapsed for transporting or quickly unfurled for decoying, will move with wind, and are lightweight, durable and effective. Formed or molded heads may be added for additional realism.

  • Patent number: 6050019
    Abstract: This invention securely holds a fishing rod and reel in a variety of situations and automatically sets the fishing hook when a fish strikes the baited hook or lure. Adapters hold the vertical stand either on a pond bank, a boat or dock rail, or dock flooring. The vertical stand pivotally supports a rod and reel holder, which is configured to hold the fishing tackle securely and without damage. The fishing line is looped under the trigger lever, which is raised and rotated by the pull on the fishing line when a fish strikes the bait. The catch arm is released as the trigger lever is lifted. The rod and reel holder is spring loaded and pivots around the support point when the catch arm is released, thus snapping to a more upright position, which action sets the hook.

  • Patent number: 6050025
    Abstract: An insect killing system optimized for mosquitoes uses multiple thermal gradients to simulate the breathing and body heat from animals, including human beings and fowl, to attract insects for subsequent electrocution. The system comprises an elongated, generally parallelepiped housing supported upon a lower base. A heating tower shrouded by the housing supports a spaced apart, generally pyramidal roof. Several slits penetrate the base to permit air entry. An internal fan draws air into the base where the air mixes with scent and pheromones. Mixed air is blown into and through the heating tower. An internal baffle divides the tower interior into separate, spaced apart compartments. A lower compartment houses a heater, and an adjacent upper compartment vents warmed air to atmosphere, creating numerous separate streams of warmed air that, to an insect, emulate human breathing. The baffle restricts air flow to create a pressure differential while ensuring adequate residence time to sufficiently warm the air.
