TIME LAG—The delay in a servosystem between the application of the input signal and the actual
movement of the load [15].
TIMER—See SYNCHRONIZER [18].
TINNING—The process of applying a thin coat of solder to materials prior to their being soldered; for
example, application of a light coat of solder to the filaments of a conductor to hold the filaments in
place prior to soldering of the conductor [4].
TOLERANCE—(1) The maximum permissible error or variation from the standard in a measuring
instrument. (2) A maximum electrical or mechanical variation of specifications that can be tolerated
without impairing the operation of a device [1].
TONES—Musical sounds [10].
TONE-TERMINAL SET—Equipment that converts TTY dc pulses into audio tones for modulation of a
transmitter in audio-frequency-tone shift transmissions [17].
TOP-HAT—An antenna that is center-fed and capacitively loaded [17].
TORQUE—A measure of how much load a machine can turn. This measurement is expressed either in
ounce-inches for torque synchro systems or in pound-feet for heavy machinery [15].
TORQUE DIFFERENTIAL RECEIVER (TDR)—A type of differential synchro that takes two electrical
inputs, one to the rotor and one to the stator, and produces a mechanical output. The output is the
angular position of the rotor that represents the algebraic sum or difference of the two electrical inputs
[15].
TORQUE DIFFERENTIAL SYNCHRO SYSTEM—A synchro system containing either a TDX or a
TDR. This system is used in applications where it is necessary to compare two signals, add or subtract
the signals, and furnish an output proportional to the sum or difference between the two signals [15].
TORQUE DIFFERENTIAL TRANSMITTER (TDX)—This type of synchro is functionally the same as
the CDX, except that it is used in torque systems rather than control systems [15].
TORQUE GRADIENT—A term used in the rating of torque synchros. It is expressed in the number of
inch-ounces of torque required to pull a specific synchro 1 degree away from its normal position; for
example, 0.4 inch-ounce per degree [15].
TORQUE RECEIVER (TR)—A type of synchro that converts the electrical input supplied to its stator
back to a mechanical angular output through the movement of its rotor [15].
TORQUE SYNCHRO SYSTEM—A synchro system that uses torque synchros to move light loads such as
dials, pointers, and other similar devices [15].
TORQUE TRANSMITTER (TX)—This type of synchro is functionally the same as the CX, except that it
is used in torque synchro systems [15].
TORQUE VECTOR—In a gyro, a vector representing the rotary motion applied to change the direction of
the rotor axis. The torque vector represents the axis about which the applied force is felt [15].
