TELEPRINTER ALPHABET (contd) :
3. A list of the above thirty-two characters and their values (if
any) on the figure-shift, with its cross-and-dot representation
opposite each, viz.:
TEMP :
A message containing observations of pressure, humidity, and temperature
at successive levels in the upper atmosphere above a particular meteorological
station.
TEPHIGRAM :
A diagram showing the condition of the atmosphere at different levels
in terms of its temperature, t and entropy, phi (i.e. extent to which
the total energy of a system is randomly distributed in that system and
therefore unavailable in that system).
TEST-PLATE :
A Hollerith machine, incorporating a form of the Enigma machine, designed
to produce a complete record of the 17576 consecutive encipherments of a
single letter, of a series of letters (e.g. the word eins), or of the
whole alphabet, when the wheel-order, ringstellung, and stecker are known.
TETRA :
TETRAGRAM :
A set or group of four letters, figures, letters and figures, or other
symbols, esp. when forming a repeat or click.
THRIPPLE :
1. (especially in Met. ciphers) To substitute two three-figure groups
for a five-figure group such that the non-carrying sum of the third
figure of the first group and the first figure of the second group
is the middle figure of the original five-figure group, the other
four figures being unaltered. (This splitting of five-figure groups
is normally done before recipherment).
2. (of two three-figure groups arising from the above process) To be
reduced (to a five-figure group) by the non-carrying addition of the
third figure of the first group and the first figure of the second.
