Fence to Ferro-silicon

face.
Fence. (Wood wk.)An adjustable metal bar or strip mounted on the table of a circular saw to act as a guide and to insure a parallel cut.
Fender. (Furn.) A metal guard, often quite decorative, placed before the open fire to protect the floor. (Mech.) Guard, usually over wheels to pre­vent the throwing of water or dirt, as the fenders of an automobile. (Print.) Pieces of cardboard glued to the tympan to prevent a sheet from slipping over the guides.
Fenestral. (Arch.) In early times a frame on which oil paper or thin cloth was fastened to keep out wind and rain, before or when windows were not glazed.
Fenestration. (Arch.) The design or arrangement of the window of a building.
Feretory. (Arch.) A shrine, either port­able or fixed, in which the relics of saints are kept.
Fermentation. (Chern.) A chemical decomposition of an organic com­pound induced by living organisms or by chemical agents.
Feffite. A group of iron compounds which have weak but permanent magnetism or which are ferri­magnetic in nature used as cores in high frequency electronic circuits b~cause they are immune to eddy current losses.
Ferrite core antenna. An antenna, used chiefly for AM reception, con­sisting of wire windings around a core of ferrite. Adv'antages are: compact size, good sensitivity and high directionality.

Ferrite head. Small ring of ferrite material slipped over signal-carry­ing wire to raise inductance at that point. Acts barrier to unwanted RF. Also; material used in construc­tion of some tape record/replay heads.
Ferrochromium. (Metal.) A chro­mium-iron alloy used in the manu­facture of chromium-alloy steels. With a carbon content of 5 per cent it is used in making tool, cutlery, and automobile steels. With a low­carbon content it is used in making stainless steels.
Ferroelectric. Pertaining to a sub­stance that possesses magnetisation in the absence of an external mag­netic field.
Ferromagnetic. Pertainign to a sub­stance, as iron, that can possess magnetisation in the absence of an external magnetic field.
Ferromanganese. (Metal.) An alloy of 20 to 80 per cent of manganese and 5 to 7 per cent of carbon in powder form is added to the mol­ten metal in the ladle. Acts as a deoxidizing agent and counteracts the influence of an excess of sul­phur. Used especially when the mix contains a large proportion of steel scrap.
Ferro-nickel. (Metal.) A nickel-steel alloy used for rheostats and coils.
Ferro-phosphorous. (Metal.) An iron of high phosphorous content used in making steel for tin plate.
Ferro-silicon. (Metal.) A hard steel containing 97.6 per cent iron, per cent silicon, and 0.4 per cent carbon.

Ferro typing to Fielded
Ferro-typing. (Photog.) Giving the face of the print a high gloss by pressing it while wet on a surface of high luster, such as that of glass, chromium plate, or japanned sheet iron.
Ferrous. (Chern.) Pertaining to iron compounds in which the metal is blivalent, or to iron with that va­lence.
Ferrule. (Mech.) Ring of metal en­closin~ and confining the wood around the tang of an edged tool to
prevent splitting. (Plwnb.) A metal­lic sleeve, calked or otherwise joined to an opening in a pipe. into which a plug is screwed which can be re­moved for the purpose of cleaning or examining the interior of the pipe.
Fertilizer. (Chern.) A combination of chemicals usually in powdered form used for improving the quality of the soil..
Festoon. (Arch. and Furn.) An orna­ment of carved work, representing a garland or wreath of flowers or leaves. or both.
Fettle. (Cerarn.) To remove lines left on cast or pressed ware by the joints of a mold.
F-head engine. (Auto.) A combina­tion of the L-head and I-head types. Intake valves are over-head and the exhaust valves are in the cylinder block. This style engine is not much used.
Fiber. A thread; any tough, thread­like substance capable of being spun and woven.
Fiber-glass. (Plast.) See GLASS CLOTH. Fiberlic. (Bldg.) A trade name for a particular type of building board.

Fibrous. As applied tothe structure of metals; the opposite of granular.
Fiddle-back. (Fum.) Name given to a chair in which the back panel is somewhat similar to a fiddle in shape.
Field. (Elec.) The space occupied by electric or magnetic lines of force. (Tel.) One set of scanning lines making up a part of the final pic­ture. In present standards, pictures are transmitted in two fields of al­ternating lines which are interlaced to form a 625-line picture at the rat~of 25 complete pictures or frames per second.
Field book. (Elec.) A blank book used by engineers and others for making notes "on the job."
Field coil. (Elec.) The coil or wind­ing around the field magnets or pole pieces of a motor or genera­tor.
Field core. (Elec.) The iron projec­tion usually salient. upon which is wound the field windig of a genertor ro motor.
Field density. (Elec.) The density of the magnetic field or the magnetic flux, measured in the number of lines of force per unit area, is de­pendent upon the strength of the field elements, the number of turns of wire, and the size and characteristics of the pole piece.
Field distortion. (Elec.) The distor­tion of the normal field existing between the north and sauth poles of a generator due to the counter­electromotive force generated in the armature windings;
Fielded. Applied to a panel which
