  • Patent number: 10023821
    Abstract: The present invention relates to an apparatus comprising a reactor body to which gas and water are supplied to create a gas hydrate; an upper cover which is engaged to an upper portion of the reactor body, a scraper mounted rotationally within the reactor body, and a motor for providing a driving force to the scraper. It is possible to remove gas hydrate particles attached to at least one of an inner surface of the reactor body and an inner surface of the upper cover, by a rotary driving of the scraper. According to the invention, it is possible to prevent a material hindering a heat transfer by attaching on a wall surface of the reactor, through a process of scraping out gas hydrate particles, when the scraper which is rotationally driven about a center axis of the reactor is close to the inner surface of the reactor.

  • Patent number: 9838988
    Abstract: The present invention relates to fine-tuning a time delay of a relay device that distributes and relays a signal from a femto base station to several antennas by using an unshielded twisted pair cable (UTP). That is, by measuring a UTP time delay between a signal distribution device, which is a component of a UTP femto distribution and relay device, and a plurality of remote signal transmission and reception devices, respectively, a cable time delay between devices is corrected so that the plurality of remote signal transmission and reception devices may relay femtocell signals at the same time.
