Temperature indicating utensil
Abstract
Abstract A UTENSIL, FOR EXAMPLE A FORK, FOR MEASURING AND INDICATING THE INTERNAL TEMPERATURE OF FOOD, COMPRISES A HANDLE WITH IMPALING MEANS, FOR EXAMPLE FORK TINES, EXTENDING THEREFROM TO BE INSERTED INT THE FOD FOR MANIPULATING IT. THE IMPALING MEANS TERMINATES IN A TUBULAR MEMBER HAVING A SHARP TIP TO FACILITATE PENETRATION OF THE FOOD. MOUNTED WITHIN THE TUBULAR MEANS AT THE TIP IS A TEMPERATURE SENSITIVE ELEMENT, E.G. A THERMISTOR, WHICH VARIES, E.G. BY VARYING ITS RESISTANCE, ACCORDING TO TEMPERATURE. AN ELECTRICAL ENERGY SOURCE, FOR EXAMPLE A BATERY, IS MOUNTED WITHIN THE HANDLE, AND A CURRENT METER IS MOUNTED ON THE HANDLE. A CIRCUIT INTERCONNECTS THE TEMPERATURE SENSOR, BATTERY, AND METER SO THAT CURRENT FLOW THROUGH THE METER VARIES WITH THE TEMPERATURE SENSOR AND THEREBY INDICATES THE TEMPERATURE AT THE TIP OF THE TUBULAR MEMBER.
