  • Patent number: 6185932
    Abstract: Disclosed is a quick-heating catalytic converter which allows the reduction of the unwanted emissions or pollutants created by the operation of an internal combustion engine. It comprises a catalytic converter system and an electronic heating catalytic system. In the catalytic converter system, the exhaust created by the operation of an internal combustion engine is oxidized or reduced to harmless emissions in the presence of a catalyst. The electronic heating catalytic converter system is located at a front position of the catalytic converter system and preheats the exhaust, comprising a power inverter circuit for inverting a direct current into an alternating current, a temperature-controlling circuit for controlling the temperature of the catalytic converter system, and a quick microwave heating circuit for quickly increasing the temperature of the catalytic converter within a few seconds to such an extent that the catalyst can readily function to purify the exhaust.

  • Patent number: 4582213
    Abstract: The present invention comprises a sanitary beverage container having an enclosed straw which is automatically straightened and repositioned above the container when it is opened by pulling back the opening tab thereof. The straw is so positioned that the lips and the mouth do not contact the top or walls of the container while drinking the contents from the container, thereby avoiding contamination and bacteria frequently associated with the top and sides of the container.
