  • Patent number: 7501608
    Abstract: The present invention provides a microwave oven and a method of operating a microwave oven, which minimises user involvement when heating a food item to a desired target temperature. According to the invention, the initial temperature of the food item is measured prior to the heating process, and the required heating time is determined automatically based on the initial temperature, the target temperature, and the amount of food as entered by the user. In order to heat a food item to a desired target temperature, the user only needs to position a container for temperature measurement and enter the amount of food. In particular, the present invention is preferably adapted for heating of baby food, such as baby milk contained in a baby bottle, and in such case the target temperature is preferably preset to about 37° C.

  • Patent number: 7495197
    Abstract: In a method for heat treating a fuel assembly channel made of zircaloy, the channel is continuously moved relative to a heat-treatment device and, longitudinal sections of it are heated to the beta phase range in an inductive heating zone. The longitudinal section of the channel heated in this manner is than cooled in a cooling zone to a temperature within an alpha phase range. The heat treatment is effected by at least two heating devices, which are spaced apart from one another, operate independently of each other, and each contain at least one induction coil and together form a heating zone. The channel section is first heated using a first heating device and then heat-treated using a second heating device which has less power and in that cooling is effected using a stream of inert gas applied to the outer surface of the channel.

  • Patent number: 7491916
    Abstract: A portable induction tool is provided for soldering or brazing sections of metal pipe together. A work coil head (with induction coil) is U-shaped, allowing placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made. In one form, the tool uses heat pipes to remove thermal energy from the head, and also a heat exchanger for higher-powered units. Power capacitors are generally included with the induction (work) coil to create a tank circuit of a resonant frequency. The induction coil uses Litz wire, copper tubing, or heat pipes with a conductive outer skin to carry the high-current being delivered to the induction coil. The induction coil has a general racetrack configuration, which is typically wound in a U-shape (or as a semicircle) as a single winding, with multiple turns.
