Longitudinal to Lowwing

Longitudinal dihedral angle to Loss factor

Longitudinal dihedral angle. (Aero.) The difference in angle of hoth wing and stabilizer settings. When the angk of the stabilizer setting, referred to the thrust line, is less than the angle of wing setting, this angle is positive.
Longitudinal st'ction. (Draw. alld Shopwk.) A section taken through a part in the direction of its length.
Longitudinal stability. (Aero.) Stabi­lity with reference to distrurhances in the plane of symme~ry, i.e.. as the pitching and variation of the longi­tudinal and normal velocities.
Long letter. (Prillt.) One that has both ascending and descending strokes, e.g.,j. .
Long screw. (Plumb.) A nipple 6 in. long with one thread much longer than the ordinary thread.
Long-shunt compound connection. (Elec.) A type of connection which occurs when the shunt-field wind­ing is connected across or in paral­lel with the combined armature and series field winding; contrasted with short-shunt connection, where the shunt field is connected directly across or in parallel with the arma­ture only.
Long-stroke. (Auto.) An engine in which the length of stroke consi­derably exceeds the diameter of the bore. Long ton. 2240 lb.
Loom. (Elec.) Flexible nonmetallic tubing used to protect electrical con­ductors.
Loop. (Aero.) A maneuver executed in such a manner that the airplane follows a closed curve approxi­mately in a vertical plane.
Loop or circuit vent. (Plumb.) A continuation of a horizontal soil or waste pipe beyond the connection at which liquid wastes from a fix­ture or fixtures enter the waste or soil pipe. The extension is usually vertical immediately beyond its connection to the soil or waste pipe. The bm:e of the vertical portion of the vent may be connected to the horizontal portion of the soil or waste stack between tixtures con­nected thereto.
Loop wiring. (Elec.) When electri­cal conductors are looped into and out of each outlet on the circuit.
Loose dowel. {Patmkg.} A dowel which is not fitted tightly to a part, but makes a sliding fit to permit its removal.
Loose fit. {thread, class I} (Mach.) Used when accuracy is not essen­tial.
Loose knot. (Wood) A knot which is notlirmly held in place by growth or position.
Loose pulley. (SllOpwk.) The idler or carrier pulley of a pair. on which the belt runs when the machine which the belt has to drive is not in use. When the machine has to be driven, the. belt is shifted from the loose to the fast pulley.
Loper. A swivel used in rope-mak­ing.
Loss. The opposite of gain in a cir­cuit; describing signal attenua­tion. Also see "insertion loss". Loss factor. (Elec. Plast.) The prod­Lost motion to Low-wing monoplane
Low brass. (Metal.) A.yellow brass alloy of 80 per cent copper and. 20 per cent zinc. It is ductile and easily drawn, and is used for formed and drawn parts.
Low carbon steels. (Metal.) Those containing less than 0.30 per cent carbon. Such steels can be casehardened but cannot be tem­pered. '
Low case. (Print.) A type case which contains only a small amount of type;
Lowenher"Z thread. (Mach.) A German thread with flats at top and root, similar in appearance to U.S.S. thread but having a different included angle.
Lower case. (Print.) Small letters not capitals.
Low finish. (Paper) A dull paper . finish such as eggshell or vellum.
Low gear. (Auto.) The arrangement of change gears which provides the slowest forward speed. (See first gear.)
Low in line. (Print.) Type lower than the adjacent type or material.
Low~pressure laminates. (Plast.) Es­sentially, laminations made at room temperature, with low pres­sure or with none.
Louver. (Arch. and Mech.)A window designed for ventillation having slats sloped to keep out the rain.A shrouded openings as on the side of an automobile hood,or on the doors of steel lockers.

Low tension. (Auto. Elec.) The primary circuit (6 volts).
Lowboy. (Furn.) An English dressing Low to paper. (Print.) Worn type, table or small table with several i.e.i lower than new type. drawers down the front. They are usually not more than 48 in. high
Low-wing monoplane. (Aero.) A . monoplane whose wing or wing uct of the power factor and the di­electric constant.
Lost motion. (Meeh.) The difference in the rate of motion of driving and driven parts, due to faulty fittings, slips. etc.
Loudnt,!SS. Subjective aural sensation related logarithmically to objective sound intensity. Generally, loudness levels are measured in phons, with zero at the hearing threshold, though a unit of actual loudness magnitude is the sone, one sone corresponding to a level of 40 phons.
Loudness control (Contour). A cir­cuit which counteracts the reduced sensitivity of the ear to very low and high notes at low volume levels.
Loud-speaker. Transducer system for cOllverting electrical energy into sound energy. Fed by a power am­plifier to reproduce music and. speech.
