Abstract: A combination flying toy/beverage can insulator comprising an insulating cylinder and weighted nose ring for fixing the center of gravity of the device at a point about 12% to 18% of the full length of the device distal from the leading edge of the device.

Abstract: A transportation system for moving passengers comprising a plurality of terminals interconnected by a track network, upon which are supported a plurality of independent and individual self-guided vehicles. Each terminal has a plurality of Automated Ticketing machines (ATMs) for automated bank account or credit line debiting and for producing passenger tickets with coded destination information. Each vehicle has a body for carrying up to two passengers, wheels for supporting and moving the vehicle, driving and braking means, a wireless data link, and a Vehicle Control and Data Processing Computer (VCDPC). Each VCDPC reads the coded destination information on a passengr's ticket, computes a travel route, controls the driving and braking means, and stores operating data. Each vehicle also has mounted thereto an Identification and scanning Device (ISD), carrying vehicle identity information and operating under the control of the VCDPC.

Abstract: A mechanical robot having hydraulically operated arms, mandible claws, neck, head and jaw, resembles a giant prehistoric reptile. It is driven from an on-board cockpit and is capable of picking up an automobile and crushing it, then biting into it with large teeth located within a powerful jaw. Various audible and visual effects are produced during operation thereby generating a frightful spectacle for exhibition, promotion and entertainment. The robot is capable of folding into a rigid structure and being attached to a trailer tractor for road hauling on its own wheels.

Abstract: A snap-on retention ring by which a hospital pharmacist can easily attach an additive cap over a sealed closure of a medical liquid container after the pharmacist has added supplemental medication to the container. The retention ring can be of a bright color as a reminder to a nurse that additive drugs have been applied to the container and special instructions should be read carefully.

Abstract: A combination motorcycle and hang-glider comprising a triangular wing formed by a flexible sheet material affixed to a trifurcated frame structure which is pivotally attached to a vehicle, such as a motorcycle suspended below the wing by a plurality of truss members, whereby the wing and the vehicles are adjustably connected to each other. The frame structure includes pivotal means and means for changing the angle of attack of the wing to provide aerodynamic lift for the motorcycle.

Abstract: An electrically powered scale model airplane is disclosed in which a rechargeable electric storage battery is positioned within the aircraft fuselage to balance the weight of a nose mounted direct drive motor. A switch for energizing the motor driving the propeller is arranged to be adjusted from an "off" position to an "on" position by remotely operated control cables acting through a bellcrank assembly used to change the orientation of the aircraft elevator during flight, thus allowing the aircraft to be operated by a single individual. The switch may be manually operated to an "off" position from the outside of the aircraft fuselage in preparation for recharging of the battery.
