Abstract: A global positioning planter system for planting of seeds by a seed planter. A population control controls the seed planter. A global positioning system computer with digitized maps connects to the population control. The population control connects to the seeder for planting of seeds such as corn or beans or to seed drills for controlling the seed drill, and plants the seeds according to the population control which receives and transmits data with the global positioning system computer.

Abstract: Astro capsule intended for use as a toy and raisable and rotatable on a four-bar linkage by hydraulic cylinders through hydraulic circuits. An electrical circuit provides for sequenced flashing flight lights, pulsating front gun lights, and for providing through a speaker a rocket sound and a phasor gun sound. The hydraulic circuits include a novel single spool for regulating flow through a valve between a combined motor pump tank to a cylinder at a fast speed up and slow speed down, and a hydraulically actuated system for rotating the capsule about its vertical axis. The vertical motion valve is mechanically linked to the joystick for ascending and descending motion and electrically controlled by the joystick for hydraulic actuation of the capsule about its vertical axis. The four-bar linkage includes a safety bar which overrides the joystick in the event that an individual or an object is positioned under the linkage in an elevated condition.

Abstract: Helicopter intended for use as a toy and raisable on a four-bar linkage by a hydraulic cylinder through a hydraulic circuit. An electrical circuit provides for alternately flashing flight lights, pulsating front gun lights, and for providing through a speaker a chopper sound and a phasor gun sound. The hydraulic circuit includes a novel single spool for regulating flow through a valve between a combined motor pump tank to a cylinder at a fast speed up and slow speed down. The valve is mechanically linked to the joy stick. The four-bar linkage includes a safety bar which overrides the joy stick in the event that an individual or an object is positioned under the linkage in an elevated condition. The hydraulic circuit is provided with a joy stick stop limit within the joy stick throttle structure, a valve control stop link, a safety bar limit, and the inherent four-bar linkage limit, all of these limits acting to keep oil in the cylinder and provide for safety of operation.
