Independent to Inductor

Independent jaw chuck to Indirect radiation

Independent jaw chuck. A jaw chuck whose jaws move independently of one another.
Independent wheel suspension. (Auto.) Front-wheel suspension by means of which the wheels react to road shocks or motion of travel independently of each other.
Indestructibility. (Phys.) The pro­perty due to which matter cannot be destroyed.
Index. (Print.) An alphabeticlly ar­ranged list of items or contents printed in a book for the purpose of quick reference. (Shopwk.) To space work off in equal divisions by means of an index head or similar device.
Index die. (Shopwk.) For certain classes of work, such as notching the edges of large disks or armature punchings, an index die is some­times used. It consists of a rotary index adapted to carry the work, step-by-step, past the punches which cut out one notch or a series of notches at each stroke of the press. Index head or dividing head. (Mach.) A mechanical device, usualIy attached to a machine, used for the purpose of spacing circular work into equal divisions.
Indexing. (Mach.) Dividing the circle into regular spaces, for purposes of mjlling, fluting, and gear cutting.
India ink. An opaque but free-flow­ ing ink used by draftsmen.
India mbber. The product made from the mikly juice of many tropical plants, which, after manufacturing processes, is widely used in the in­dustries.

Indicate. Point out; show; to point out very briefly.
Indicated horse-power. (Engin.) The horsepower as detennined from as indicator diagram.
Indicatting switch. (Elec.) A switch which shows whether current is on or off.
Indicator. (Engin.) An instrument used ot show the pressure and ac­tion of the steam in an engine cyl­inder.

Indicator card. (Engill.) Paper which is wound upon the drum or cylin­der of an indicator and upon which the diagram .of the indicator is traced.
Indicator diagram. (Engin.) A dia­gram of work traced by the pencil of the indicator upon an indicator card~
Indirect lighting. (Elec.) Lighting effect secured by throwing the light against the ceiling or some other surface from which it is diffused in the room.
Indirect radiation. (Phys.) Wann air heating system relying on a cen­tral h"eating plant to heat air to a desired temperature and then dis­tribute heated air to the space to be. wanned. by means of duct distri­bution system.

Indium to Inductor
Indium. (Metal.) A very rare metal. It is lustrous, white, soft, and ductile. Its cost makes its use prohibitive except for experimental purposes.
Individual drive. (Mach.) Refers to a direct motor drive for each unit as opposed to drive through counter­shaft from a line shaft.
Indraft. (Aero.) The flow of air into the blades from the front of the propeller.
induced angle of attack. (Aero.) The difference between the actual angle of attack and the angle of attack for infinite aspect ratio of an airfoil for the same lift coefficient.
Induced current. (Elec.) See Induc­tion.
Induced draft. (Engin.) An artificial draught produced by suction; as opposed to forced draught.
Induced drag. (Aero.) The part of the drag induced by the lift.
Induced magnetism. (Elec.) See In­duction.
Induced voltage. (Elec.) A voltage set up by a varying magnetic field linked with a wire, coil, or circuit.
Inductance. (Elec.) The ratio between the total induction through a circuit and the current producing it. The ability to oppose change in current flowing through a' circuit.
.
Induction. (Elec.) The production of magnetization or electrification in a body by the mere proximity of magnetized or electrified bodies, or of an electric current in a con­ductor by the variation of the mag­netic field in its vicinity.
Induction brazing. An electric braz­ing process wherein the heat is obtained from an induced current.
Induction coil. (Elec.) Essentially a transformer with open magnetic circuit, in which an alternating cur­rent of high voltage is induced in the secondary by means of a pul­sating direct current in the primary.
Induction compass. (Aero.) A com­pass, the indications of which de­
pend on the current generated in a coil revolving in the earth's mag­netic field.
Induction motor. (Elec.) An alter­nating-current motor which does not run exactly in step with the alternations. Currrents supplied are led through the stator coils only; the rotor is rotated by currents in­duced by the varying field set up by the stator coils.
Inductive reactance. (Elec.) The op­position to the flow of an electrical current in a circuit which consists of turns of wire. The opposition is greater if the turns are wound on an iron core. The measure of re­sistance to the flow of an a.c. current through a coil.
Inductivity. (Elec.) The capacity or power for induction.
Inductor. (Elec.) An electrical con­ ductor in which an induced e.m.f.
