The Wheatstone slip was a paper tape that contained holes in a pattern to control the mark and space signals on the telegraph line. The paper tape was from 0.46 to 0.48 inches in width, (but the standard width is from 0.472 to 0.475 inches) and a standard thickness of 0.004 to 0.0045 inches. [3] Olive oil coating lubricated the punch process. [4]
Paragraph LXVII sets out the fine for wounds of various depths: one inch, one shilling; two inches, two shillings, etc. [m] An Anglo-Saxon unit of length was the barleycorn.

The Gerke code had only one length of dash and all inter-element spaces within a code point were equal. Gerke also created code points for the German umlaut letters, which do not exist in English. Many central ...
Baudot developed his first multiplexed telegraph in 1872 [3] [4] and patented it in 1874. [4] [5] In 1876, he changed from a six-bit code to a five-bit code, [4] as suggested by Carl Friedrich Gauss and Wilhelm Weber in 1834, [3] [6] with equal on and off intervals, which allowed for transmission of the Roman alphabet, and included punctuation and control signals.
DASH is capable of recording two channels of audio on a quarter-inch tape, and 24 or 48 tracks on 1 ⁄ 2-inch-wide (13 mm) tape [1] [2] [3] on open reels of up to 14 inches. The data is recorded on the tape linearly, [ 4 ] with a stationary recording head , [ 5 ] as opposed to the DAT format, where data is recorded helically with a rotating ...
