  • Patent number: 5587099
    Abstract: A safety container for a baking utensil provided with a thermal heating element having ferrites dispersed therein, which utensil when placed in a microwave oven and is exposed to microwave energy, converts this energy into thermal energy for cooking the food therein. The safety container in which the utensil is housed includes a removable cover and a temperature-responsive latching mechanism which releases the cover to permit withdrawal of the utensil from the container only when the utensil has cooled to a temperature level at which it is safe to handle.

  • Patent number: 5396051
    Abstract: A mold assembly for use by children to produce in a microwave oven plastic play pieces. The assembly includes a mold, non-reactive to microwave energy and is provided with shaped cavities for receiving a flowable, plastic molding composition non-reactive to microwave energy and having a predetermined curing temperature. Underlying the cavities is a thermal heating element formed by microwave energy-absorbing ferrite particles dispersed in an inert matrix. The particles have a Curie point higher than the curing temperature of the molding composition so that the heating element heats the composition in the mold cavities to effect curing and hardening thereof, thereby forming the play pieces. The mold assembly is enclosed within a safety container non-reactive to microwave energy.

  • Patent number: 5244153
    Abstract: Present invention is a water gun nozzle assembly for attachment to the barrel of a water gun having an egress path for shooting water through a nozzle. The nozzle assembly includes a nozzle head with an orifice for connection to an egress path of a toy water gun, a support for the nozzle head, a housing, and a handle. The housing is attachable to the barrel of a water gun with the support and nozzle head located within the housing and rotatably mounted therein, so as to sweep left to right and vice versa, with the support extending to the outside of the housing. The end of the support which extends outside of the housing is directly or indirectly connected to the handle. When the handle is indirectly connected it may be located elsewhere on the barrel or otherwise on the gun and rotatably connected indirectly to the support by a belt, gear, chain or other rotatable drive mechanism.
