Mechanical Definitions |
Index Center : One of two machine-tool centers is used
for holding work and rotating it by a fixed amount. |
Index Counter : It is a counter which indicates revolutions
of the tape supply reel and makes it possible to index selections
within a reel of tape. |
Index Error : It is an error which occurs because of
misalignment of the vernier and the graduated circle of an instrument.
|
Indicator : An instrument is used to obtain a diagram
of the pressure-volume which changes in a running positive-displacement
engine, compressor or pump cylinder during the working cycle.
|
Indirect Cost : It is a cost which is not readily identifiable
with or chargeable to a specific product or service. |
Induction Burner : It is a fuel-air burner in which the
fuel is fed under pressure to entrain required air into the
combustion nozzle area. |
Induction Log : It is an electric log of the conductivity
of rock. The depth is obtained by lowering into an uncased borehole
a generating coil which induces eddy currents on the rocks and
these are detected by a receiver coil. |
Induction Pump : A type of pump which is operated by
electromagnetic induction. |
Inertia Governor : It is a speed-control device or tool
which utilizes suspended masses that respond to speed changes
by reason of their inertia. |
Inertia Starter : It is a device or tool which utilizes
inertial principles to start the rotator of an internal combustion
engine. |
Inert Primer : It is a type of cylinder that enshrouds
a detonator without interfering with the detonation of the explosive
charge. |
