  • Publication number: 20250121144
    Abstract: A vortex tube assembly and a breathing device include a main tube and a hot end plug. Gas inlet slots are annularly defined on a side surface of the main tube, so that compressed gas entering the main tube forms a vortex airflow. A first end of the main tube is a cold gas outlet connected to a turbine fan to dissipate heat. A second end of the main tube is a hot gas outlet. The hot end plug is mounted on the hot gas outlet of the main tube. A middle portion of the hot end plug blocks the vortex airflow close to an axis of the main tube, and hot gas outlet annular holes are defined around the middle portion of the hot end plug, so that the vortex airflow close to a tube wall of the main tube flows out from the hot gas outlet.

  • Publication number: 20180081192
    Abstract: The present invention creates a new way of arranging harsh marks on a reticle that is to have the 2/10th and the 4/10th hash mark placed either above or below the horizontal base sighting line (See FIG. 2. Line 26) or on the left or right side of the vertical sighting base line (See FIG. 2. Line 27) at any unit of measurement of a segment and have the 6/10th and the 8/10th hash mark placed at the opposite side of the horizontal base sighting line (See FIG. 2. Line 26) and the vertical sighting lines (See FIG. 2. Line 27) compared with the 2/10th and the 4/10th marks. This new way of placing hash marks at every 2/10th of the unit of measurement allows a user to quickly identify and discern which numerical value a hash mark represents on the horizontal base sighting line and vertical sighting line without physically counting the numerical value of a hash mark in a linear way.
