  • Patent number: 4292755
    Abstract: This invention relates to an air-floating saucer toy, comprising a housing, of which the main dynamic elements including saucer, air pump, electric motor, speed-reducing device, pneumatic tube and batteries are carried. The saucer is driven to float along a circular slot in the housing by the pneumatic discharge from the air pump through an injection nozzle at the outer end of the pneumatic tube, which travels in a circular path below the slot, the saucer thereby moving along an orbit corresponding with the slot and in the same direction as the end of the tube.

  • Patent number: 4268978
    Abstract: The present invention relates to an automatic sound-emitted self-learning toy characterized by effectively emitting the sound "YES" while the selected answer card coincides with the question card on the base sheet, and "NO" while the two are not in accordance with each other. The answer card, question card and basic sheet are provided with a magnet, when the corresponding magnets are located so as to be attracted to each other, the tape recorder within the rear body connected to the mechanism under the basic sheet will selectively emit the sounds "YES" or "NO" so that children may learn calculation while playing the toy.
