4:3 (1.33:1) (generally read as Four-Three, Four-by-Three, or Four-to-Three) for standard television for fullscreen aspect ratio 1.33:1 has been in use since the invention of moving picture cameras, and many computer monitors used to employ the same aspect ratio. 4:3 was the aspect ratio used for 35 mm films in the silent era.
From 1982 to 1986, the original bridge deck, in 747 sections, was replaced with lighter, stronger orthotropic steel deck panels over 401 nights without closing the roadway completely to traffic. [5] The project not only restored the bridge to prime condition but also reduced the deck weight by 12,300 tons (11,160 metric tons ).
This compares to the 0.866" by 0.732" (approx. 22 mm x 18.6 mm) frame of a modern anamorphic 35 mm negative, which provides a frame area of 0.64 sq. inch. On the print film, however, there was a smaller frame size of approximately 1.34" x 1.06" (34 mm x 27 mm) to allow space for the 6 magnetic soundtracks.
A general practice is to size the sleeve two NPS (pipe sizes) up from the diameter of the penetrant. For example, a 4" pipe, with 1" of thermal insulation makes a 6" penetrant (1" pipe covering on each side of the pipe), plus two pipe sizes = an 8" sleeve, creating a 1" annulus.
It is also used in computer monitors, where the term "21:9" can represent aspect ratios of 43:18 (2.3 8:1 or 21.5:9) and 12:5 (2.4:1 or 21.6:9) in addition to 64:27. The wider screen provides advantages in multitasking as well as a more immersive gaming experience, [ 3 ] [ 4 ] and even wider screens with aspect ratios such as 32:9 (allowing for ...
Heat-shrinkable sleeves are applied onto the cutback at the field weld or "field joint" during the construction of a pipeline. As described above, the heat-shrinkable sleeves have an adhesive that sticks the sleeve to the cutback and the factory applied mainline coating and also acts as a corrosion protective layer.
1 ⁄ 4-length sleeve or quarter-length sleeve: A sleeve that extends from the shoulder to midway down the biceps and triceps area. 3 ⁄ 4-length sleeve or three-quarter length sleeve: A sleeve that extends from the shoulder to a length midway between the elbow and the wrist.
