Face Represents: The display of a radar is either a circular cathode ray tube (CRT) from five to twenty inches in diameter, or a rectangular "raster-scanned" view using a CRT or an LCD. The center of the face represents represents the position of the radar-equipped vessel and the presentation is roughly like that of a navigational chart. The presentation can be in color, or in several intensities of green (CRT) or shades of gray (LCD).
A bright radial line on the face represents of the tube represents the radar beam; it rotates in synchronism with the antenna. Reflections show up as points or patches of light depending upon the size of the echo-producing object. The persistence of the screen is such that the points and patches of light do not completely fade out before the antenna has made another rotation and the lights are restored to brilliance. Thus the picture on the radarscope is repainted every few seconds.The most important qualities for hair are that it be healthy, shining, and in a flattering, easy-to-manage style. Many fashion magazines suggest hair styles according to the shape of the face represents in order to make the face represents resemble as closely as possible the perfect oval. The circularity of a round face represents may be minimized by a sleek, controlled style with side bangs. A square face represents needs a style that cuts across the square corners at the temples and is full around the jaw. The best style for a long face represents also rounds off the corners at the temples and is short. For a triangular face represents, a narrow chin should be filled out with chin-length hair, while a wide chin may be minimized with wide bangs. In finding the right hairstyle, however, a woman should also consider the proportions of her whole figure, the texture of her hair, her skill in handling it, and the character of her life.
After the fluid has raised and passed the gate, the pressure being removed from the face represents of the Sate it closes thereby checking or stopping _the uid from flowing in the reverse direction. Fig. 11 represents the foot valve, its use and operation being similar to the check valve. It is used, however, in a vertical pipe and at the end of the suction pipe of a pump. Air Valves are made for two common purposes, namely: To be placed on mains at high points where air accumulates and obstructs the flow of water and for use on pipe lines to permit air to enter when water is drawn off, and to allow air to escape when pipes are being refilled. The former, the lever-and-float air valves, are shown in Fig. 12. |
