Abstract: Heat alert safety device for warning individuals that a surface is hot wherein a fiber optic cable runs from an electric light source to a heat warning symbol. The cable has a plurality of fibers connected at a first end thereof to the light source and transmits light from the light source beginning from the first end to the second end of the cable and shines light out of the second end of the cable to a predetermined symbol adjacent the second end of the cable. The symbol is readily visible when illuminated to an observer who can also readily see the surface and the symbol communicates that the surface of the stove, in particular, the heating element, is dangerously hot. A controller controls the light source Whenever a specified surface temperature is reached, the symbol is lit and remains lit as long as said specified surface temperature is maintained.

Abstract: A hot-button type heat alert safety device attachable to a surface, such as metal or glass, for warning individuals that the surface is hot, comprising a thermochromic composition, a button-shaped container for housing the composition, having a convex face, the convex face overlying said composition and the container being transparent in at least a portion of the container overlying the thermochromic composition. The thermochromic composition is designed to undergo and maintain a readily perceptible color change whenever the temperature of the hot surface exceeds a predetermined temperature and reveal a heat warning symbol underneath the thermochromic composition which communicates that the surface is dangerously hot, the heat warning symbol being substantially visible through the convex face of the container.

Abstract: Heat warning device for warning that a surface is hot. Fiber optic cable having a plurality of fibers surrounded by a protective sheathing runs from an electric light source controlled by a controller. The plurality of fibers at first end of the cable adjacent the light source transmit light to illuminate a predetermined warning symbol adjacent the side of the cable, on the protective sheathing of the cable as a cut-out, at a long spaced interval from the second end of the cable or anywhere else. The illuminated heat warning symbol is visible to an observer who sees that the surface is dangerously hot. Whenever a specified surface temperature is reached, the symbol is lit and remains lit. Alternatively, the cable transmits to a receiving medium spaced from a second end of the cable an image of the symbol positioned between the light source and the first end of the cable.

Abstract: A disposable grill cover for indoor counter top grills having two cooking plates such as the George Foreman® grills contains a first and second sheet or sheet portion of aluminum foil of a fixed shape designed to mate with the two contoured cooking surfaces of the grills. The sheets are positioned over the cooking surfaces of the grill using tabs on each side of the sheets extending the same layer of aluminum. The contoured surface including ribs/grooves and bumps of the two sheets correspond exactly to the contoured surface including ribs, bumps and a rim on the two cooking surfaces of the grill to minimize heat loss. Cleaning the grill from fat, grease and odor from food residue is avoided before each use.
