Non-printing characters or formatting marks are characters for content designing in word processors, which are not displayed at printing. It is also possible to customize their display on the monitor. The most common non-printable characters in word processors are pilcrow, space, non-breaking space, tab character etc. [1] [2]
A Boxpok is a steam locomotive wheel that gains its strength through being made of a number of box sections rather than having traditional solid spokes (the name is a variation on "box-spoke"). Being hollow, they allow better counterbalancing and stability than conventional drivers, which is important for fast locomotives.
The z/Architecture, which is the 64-bit member of that architecture family, continues to refer to 16-bit halfwords, 32-bit words, and 64-bit doublewords, and additionally features 128-bit quadwords. In general, new processors must use the same data word lengths and virtual address widths as an older processor to have binary compatibility with ...
The PDP-10 uses word addressing with 36-bit words and 18-bit addresses. Most Cray supercomputers from the 1980s and 1990s use word addressing with 64-bit words. The Cray-1 and Cray X-MP use 24-bit addresses, while most others use 32-bit addresses. The Cray X1 uses byte addressing with 64-bit addresses. It does not directly support memory ...
Boxpok wheels were proposed for the forthcoming Victorian Railways R class 4-6-4, which had a relatively heavy 19.5-long-ton (19.8 t) axle load, but it had been discovered that the use of a Boxpok wheel would make coupling rod pin removal difficult. The SCOA-P wheel was developed to allow the strength of the Boxpok design but also provide the ...
The Bulleid Firth Brown, or BFB, is sometimes, but inaccurately, referred to as a Boxpok in reference to the wheel used by a number of US railway companies. The BFB is visually similar to the Boxpok, but is of a different design; the Boxpok is composed of sections fixed together to make a hollow shape, while the BFB is cast in a single piece, like a spoked wheel, the shape giving the rigidity ...
The USRA Light Pacific was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I.
The type combined the basic design principles of the 4-6-2 type with an improved boiler and larger firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the 4-6-2, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was ...
