  • Patent number: 9242208
    Abstract: A regenerating-type compressed air drier for regenerating compressed air by an electrical heating mechanism and a dehumidifying-and-regenerating unit are provided. The drier includes a dehumidifying-and-regenerating unit and an air distribution unit. Compressed high-humidity air and regenerating air are guided to the air distribution unit by a compressed high-humidity air piping and a regenerating air piping. The compressed high-humidity air and the regenerating air are guided to dehumidifying-and-regenerating components of the dehumidifying-and-regenerating unit by a shunt rotor of the air distribution unit to complete the dehumidification of the compressed air and the regeneration of the dehumidifying-and-regenerating components. The drier has a simple structure, and can reduce an undue loss of heat energy by an electrical heating mechanism to the regeneration of the dehumidifying-and-regenerating components.

  • Publication number: 20130058735
    Abstract: A concrete screw includes a rod body which has a top end forming a head for tightening operation and a bottom end forming an engaging section. A first thread is formed on the rod body and extends, at a helix angle between 16 and 23 degrees, from the head toward the engaging section. The first thread has a top-side flank that defines a first thread flank angle ranging from 90 to 120 degrees with respect to the rod body. The first thread has a pitch that ranges from 5 mm to 20 mm. Three cutting notches are formed in and distributed along the first thread and are close to the engaging section. The cutting notches have a depth substantially corresponding to a distance from an apex of the first thread to the rod body. The rod body may selectively form a second thread extending between the head and the engaging section.
