  • Patent number: 11939425
    Abstract: The present invention relates to a polyester resin. The polyester resin is useful for bottles, sheets, multilayer sheets, stretched films and fiber applications due to excellent heat resistance and transparency, and in particular, the polyester resin has little deterioration of physical properties such as yellowing, etc., during processing. A process for making the polyester resin includes an esterification reaction between a dicarboxylic acid that includes terephthalic acid and a diol that includes isosorbide in the presence of a catalyst, followed by a polycondensation reaction on a product of the esterification reaction. In some embodiments, an initial mixing ratio of the dicarboxylic acid and the diol is between 1:1.02 and 1:1.04.

  • Patent number: 10690353
    Abstract: A ventilation system and a method for discharging hazardous air during cooking are disclosed. The ventilation system allows hazardous air generated by cooking to flow in a backward direction of a cooking device so as to quickly transfer the hazardous air to a hood, such that the hazardous air is prevented from being inhaled by a user. As a result, the hazardous air may be concentrated into a predetermined region without being dissipated, and then subsequently discharged outside. Information about a quality of air generated in a current state of a cooking space is transferred to a user so that the user may more actively use the ventilation system, thereby better protecting the user's health.
