  • Patent number: 5984444
    Abstract: An electrostatic three-dimensional printer in which molten material drops such as plastic and wax are given an electrostatic charge, and accelerated through a guiding magnetic field. Just as an electron is accelerated and guided in a cathode ray tube. Any molten material may be used. Parts are created by the build up of multiple layers of these droplets. When parts have overhangs a second removable material is used. In the case of plastic a lower melting point wax could be used to support the overhanging plastic then later removed from the part by melting.

  • Patent number: 5203103
    Abstract: The invention relates a fishing lure that has a flexible body or a flexible joint or joints that are moved by the actuation of a Nitinol or shape metal alloy bending actuator means. This actuator can take the form of a Nitinol wire that is placed inside the lure in such a way that when the wire is heated by passing an electric current through it, it will move causing the lure to appear to be alive. In the form of a worm a rubber fishing lure would have a thin Nitinol wire with a second non contracting wire inside the body of the worm. When the Nitinol is heated by a pulse of electricity from the electric circuit the worm bends simulating a life like motion. Because of the electric circuit the frequency and amount of movement can be controlled as well as the life of the battery.

  • Patent number: 4931028
    Abstract: A toy blimp with at least one engine, and preferably two, mounted on a top side of an inflatable helium balloon blimp like member, and an infrared control circuit and power supply mounted on a bottom side. The balloon can be aluminum coated mylar, or preferably of a material which retains helium. A remote control transmitter with push buttons transmits infrared control signals to the control circuitry on the balloon for horizontal and vertical directional control. The blimp operates from the self-contained power supply and is controlled by the self-contained control system which receives control signals from the transmitter. The blimp is intended for free flight and as an amusement.

  • Patent number: 4658171
    Abstract: The present invention is directed to an engine and method for converting heat energy to electrical current. The engine includes a heat source with a heat exchanger. Dipole antennas receive heat energy and immediately convert it to electrical current which is then rectified before flowing to a load.
