  • Publication number: 20030121349
    Abstract: The present invention discloses a forward force producing system for wheels that generates a forward force using the downward force created by the weight of the load. The force from the weight of the vehicle and the vehicle load is transferred through the forward force producing system and creates a permanent forward force. The forward force provides an impetus to the forward motion of the wheel that serves, not only to counter act the effect of surface friction between the wheel and the surface, but also to propel the vehicle forward.

  • Patent number: 5369907
    Abstract: A rodent trap operates by electrocuting the animal as it moves to steal the bait from a space above a depressible platform. The platform includes a downwardly swingable plate that is covered by a woven fabric panel. Edge areas of the fabric panel hang downwardly into a water bath located below the platform; water is drawn upwardly by wick action so that the platform fabric surface is wet. As the animal moves along the platform its feet and body become wet due to contact with the wet platform surface. The weight of the animal depresses the platform, which activates a hidden switch, thereby completing an electric circuit which electrocutes the animal while it is on the platform. The wetting of the platform surface facilitates the electrocution process.

  • Patent number: 5241779
    Abstract: An apparatus for collecting and killing insects which includes a heat source for attracting the insects to a housing, electric conductor means, for connection to a power source, to stun or kill the insects, means for collecting the insects after they are stunned or killed, and means for vacuuming the insects into a collection vessel so that they can be transported away from the apparatus and disposed. The collection vessel may be filled with oil to assure suffocation of the insects. The subject invention also can be employed in combination with conventional appliances having a heat producing element so that insect infestations attracted to the appliance can be easily disposed of by employment of the subject invention.
