    Abstract: Provided is a thawing device for improving the thawing rate by agitation of the contents in a bag. The thawing device includes a first heater and a second heater to heat a bag containing a frozen matter, and a supporting unit to support the bag. The first heater is supported at guide grooves to move back and forth, and descends by approaching the bag, and a component force in the travelling direction of the self weight acts as a biasing force. The second heater is supported via a supporting shaft, and a pressing force acts on the upper and the lower side of the bag alternately. Excessive pressing force acting on the bag is alleviated and a damage of the bag can be reduced when the second heater presses the bag even in a frozen state.

  • Patent number: 4673798
    Abstract: A dual temperature curling iron has a plastic handle and a metal barrel connected thereto. An electric heater positioned within the metal barrel and is arranged to rapidly heat the barrel and is selectively controlled by either a low temperature thermostat or a high temperature thermostat located within the barrel to provide heat to the metal barrel. A hair clamp is pivotally mounted on the metal barrel, and when opened, causes a switch to generate an in-use signal which is fed to a safety timing circuit. The timing circuit is reset each time it receives the in-use signal. In the event that no further in-use signals are received, the timing circuit, after a preselected interval, provides a signal to a silicon controlled rectifier which is connected to the electric heater causing the silicon controlled rectifier to interrupt electric power to the electric heater. The curling iron is provided with a visual signal for indicating that has reached the selected temperature and is ready for use.
