  • Patent number: 5842905
    Abstract: A simple, general purpose temporary dyeing process for coloring plastic or plastic fabric is disclosed. A colorless, but pH sensitive indicator solution is applied to a plastic material, such as the hair of a fashion doll, without changing the hair color. A developer solution of a specific pH range is subsequently applied to the doll hair, thereby causing the color of the hair to change. As the hair dries and the developer solution evaporates, the hair returns to its original color.

  • Patent number: 5736075
    Abstract: A method of molding, from porous material, a low-density product having an impermeable surface. A mold is provided, which has a cavity, the outline of which defines the outline of the product. The starting material is a flat sheet of plastic foam. The first step of the process, in some cases, is a pre-heating procedure, which softens the material. Then, from this sheet there is stamped a blank having substantially the outline of the desired product, which is then inserted into the mold cavity. The mold is then heated with the blank therein to form the blank permanently into the desired product, after which the mold is quenched in cold water with the product still inside. The product is subsequently removed from the mold and frozen. The result of this molding method is a low-density product having an impermeable surface integral with the foam interior which is suitable for receiving various types of brightly colored finished.

  • Patent number: 5527044
    Abstract: A toy simulates an arcade game. A box has a transparent side panel and contains game device that may be manipulated from a control panel at a front of a box. Here the game device is a toy boat or submarine that slides horizontally and deploys a claw to pick up objects on the bottom panel. The boat and claw have separate reversible motors which turn in one direction or the other depending upon the polarity of the applied voltage. To play the game, a user looks at the game pieces while he manipulates the controls at the front of the box in order to pick up an object and drop it through a chute.

  • Patent number: 5464213
    Abstract: A toy simulates an arcade game. A compartment at the top of a box has a transparent bottom and contains game pieces that may be manipulated from a control panel at a front of a box. A mirror in the box reflects the image of the game pieces as seen through the transparent bottom. To play the game, a user looks at the reflection image of the game pieces while he manipulates the controls at the front of the box. Here, the game is a pinball machine in which the transparent bottom has a plurality of upstanding pegs which divert balls into random paths. Any balls which are caught by a manipulation of the controls are diverted into one scoring path. Any balls which are not so caught fall into another scoring path. The invention provides for releasing a selected number of objects at one time to change the required skill level to play. Also, by changing the direction in which the transparent bottom slants, different games maybe provided.

  • Patent number: 5443261
    Abstract: A toy arcade game has a plurality of spaced parallel vertical tracks. A moving object (here a monkey) is mounted on each track to drop under gravity to the bottom of the track. An endless belt drives the object up the track. If a push button is pressed quickly enough, the object drops back to the bottom. It is not pushed quickly enough the object reaches the top of its climb. The object of the game is to push the buttons quickly enough to keep any of the objects from reaching to top of the track.

  • Patent number: 5390653
    Abstract: A two handed toss and catch toy has a pistol-like body with a drive spring biased trigger rod to store energy in a drive spring in response to a manual motion. The stored energy flings a ball upwardly when the trigger rod is released. An upwardly directed basket is provided for catching balls as they fall back to earth. A tunnel magazine extends from the basket to a position where the balls are struck by the trigger arm in order to recycle caught balls for the next flinging.

  • Patent number: 5381928
    Abstract: An action toy system including a capsule for containing water having an orifice and a plunger and a spring loaded mechanism for driving the water from the orifice. The action toy may be configured as a shotgun accepting a plurality of prefilled shell capsules into its breechblock for firing through its barrel. It may also be configured as a missile launcher in which the capsules are mounted to the front of the launcher and the water is ejected directly from the capsule against the target. In yet another embodiment, the invention is configured as a crossbow with the bow loading the spring-loaded mechanism and a water stream obtained on release of the bow. In a still further embodiment, the action toy is fitted with a double feature nozzle for either producing a stream of water or propelling an object.

  • Patent number: 5190298
    Abstract: Memory-oriented or pattern matching games use game pieces having indicia which become excited responsive to a brief exposure to strong light or another activating event for emitting colored light during a short period of time. The games use the excitable indicating medium to present certain information to the players for a short time period. Thereafter, the players are required to use their memory of the temporarily-presented information in order to accomplish some task. In some embodiments, the games present a random arrangement of color-coding which soon becomes invisible after the excitement subsides. Then, the players must use their memory of the game piece locations to select only those pieces which are assigned to them. In another embodiment of the invention, a maze is printed in excitable ink which is visible only during the short time period of excitement. The players must try to complete the maze before the pattern, or their memory of it, dissipates.

  • Patent number: 5028047
    Abstract: A game apparatus has a housing and a removable lid for covering the housing. A brief flash of high-intensity illumination is provided when the lid is removed. A number of playing pieces randomly positioned within the housing receive the illumination of the flash. The playing pieces briefly radiate color-coded visible light after receiving the flash, forming a random pattern of colored light. At least two players may view the game pieces to form impressions of the locations of the playing pieces while they are radiating the light. Each player must rely upon his memory as to where his color of playing pieces are located. The players use an implement to remove the game pieces in turn according to his memory of where colors assigned to him are located.

  • Patent number: 5006089
    Abstract: A stuffed animal has a closed fluid containing liner filled with a viscous silicon or silicon/water material. The weight of the silicon/water material gives the animal a life-like weight. The liner is covered by a fur-like plush. The viscous material may be a material used to make a prosthesis of a human organ. If desired a material such as a plastic simulation of a skeleton may be added to give a feel of bone. The "skeleton" may have a plastic memory for causing the animal to retract its leg, paw, or the like after it has been stretched. Small patches of hook and loop fasteners may be used to secure the animal in a desired posture.
