Water spots to wave motion

cleansing purposes; also any chemi­cal added to' water to accomplish this purpose.
Water spots. (Paint and Lacquer) Water spots are slight discolour­ations that appear in the film of lacquer enamels and of tentimes appear to go down very deep into the film. Usually caused by sealing in moisture.
Water table. (Arch.) A projecting, sloping member around a building to throw rain water away from the walt .
Watt. (Elec.) ~n electrical unit of power; equals volts multiplied by amperes. '
Watt hour. (Elec.) A unit of measure of electrical work, equal to one watt expended for one hour.
Wattless current. (Elec.) The com­ponent of an alternating current which does not combine with the voltage to produce power, the idle component as distinguished from the active component.
Wattmeter. (Elec.) An instrument for measuring electric power in watts; the unit of electrical energy, volt times amperes, combining therefore the functions of a voltmeter and an ammeter.
Watt second. (Elec.) A unit of meas­ure of electrical work equal to the rate of one watt expended for one second of time.
W..Uo; !H!r candle. (Elec.) Term used ::cm!11ercially to denote the con­sumption of a lamp in watts per mean horizontal candle power pro­duced. Wave. Mode of energy propagatio involving, at a given point, a suc­cession of ups and downs in sur­face level (water), pressure (sound) and intensity of field (radio);
Waveband. Band of frequencies of wavelengths for a particular pur­pose, usually 'radio, i.e., LW, MW, SW, VHF, etc.
Wave form of alternating current. (Elec.) The sine wave produced by an alternating current designating its values (instantaneous, effective, and maximum) and its polarities, for a given period of time. A sine wave showing all the characteris~ tics of that current.
Wave length. (Elec.) The length in meters of one complete sine wave of an alternating current. In radio, the distance in meters between the maximum points of two succes­sive magnetic waves sent out by a transmitter.
Wavelength, acoustic. Wavelength is the distance sound travels to complete one cycle. With an ap­proximate speed of sound at 344 metres per second, the wavelength of 30 Hz is about 11.4 meters; 1,000 Hz is about 0.3 metres, and 10.000 Hz is 3.4 cm.
Wave motion. Mode of energy propagation in which medium un­dergoes a sequence of pressures, tensions or movements correspond­

Wave trap to Wedgeing to frequency or waveform of passing "information".
Wave trap. (Radio) A combination of coil and condenser (tuner) that can be adjusted to filter out a signal at a certain frequency.
Waviness. (Plast.) Wave line uneven­ness or out-of-plane; may be on the surface.
Wax. (Chem.) An organic salt (ester) of a high monotomic alcohol and a high fatty acid; e.g., beeswax.
Wax engraving. (Print.) A process of
. making printing plates by engrav­ing on a wax-coated copper .plate, building up the' background, and making an electrotype from the plate.
Wax finish. (Woodwkg.) A very smooth finish secured by polishing a wood surface with wax prepared for the purpose.
Ways. (Shopwk.) Longitudinal guides, upon which the work or a table bearing the work may slide, as the ways of a lathe or planer.
Weak sand. (Fdry.) Sand that will not hold together due to the small per­centage of clay which gives it but little strength at the usual temper and hardness. Wear and tear. Depreciation in value . due to use.
Wear products. Debris from the tape surface or edges which acumulates on transport parts during tape use.
Weather. To season, dry, injure, or alter in any way the condition of wood, stone, or other material through exposure to the weather.
Weather-boards. (Arch.) Boards used as outside covering of buildings, nailed on so as to overlap and shed the rain.
Weathering. (Arch.) The slope given to offsets, buttresses, and the up­per surface of cornices and moldings, to throw off rain. (Wood) The wearing away of the surface of timbers caused by exposure to the elements.
Weather strip. (Arch.) A strip of metal, wood, or other material such as is used around doors and win­dows to prevent draughts.
Web. (Mech.) A thin plate connect­ing two parts of a casting, forging, etc. (Papermkg.) Paper in the proc­ess of being formed or having been on the paper machine.
Webbing. (Uphol.) Made from jute fiber in the standard width of 3, 3Y2, and 4 inches with 72 yards to the roll. Used mainly as a spring support on furniture frames.
Webbing stretcher. (Uphol.) A de­vice for stretching webbing across the ope~ings of furniture frames. It consists of furniture frames. It con­sists of a small, flat piece of wood, padded at one end, with several sharp steel points inserted in theother end to engage the web­bing.
Web-calendered. (Papermkg.) Paper calendered from a roll of paper as distinguished from paper which is calendered in the sheet.
Web of drill. (Meclz.) The thickness of a drili at the bottom of the flutes.
Wedge. (Mech.) A piece of wood, or metal, V shaped in longitudinal
