Show The Wireless Light TT WILT WILl not I be IT many years ears scientists predict before belore we will go home p press ess a button and a crystal globe having ha no wires Inside or out will cast a n pleasant light in our homes This wireless light I Is now a fac fact and Is used In several robots that surprise us by their human like per per- The new wireless light books like a crystal sphere when not lighted It has no filament Inside It to burn up and break breal and has no metal Inside or out It contains gases rendered highly high high- ly Iy luminous by a high frequency electric elec elec- current In a near-by near coil coll of wire In homes of the future mechanical these coils colls could be placed In the walls and no lighting apparatus or wires only the crystal lighting globes s would be exposed One of ot these wireless lights a huge one operator operated by radio recently was mounted on a tower In Schenectady N. N Y and it threw of oft off sufficient light to read a n newspaper two miles away Those These wonder lights cost little and give off orr almost no heat The new nev ma magic lc lI lights are similar to the neon tubes used for the new type of outdoor advertising lights but cast casta a soft glow instead of the glaring red or blue bite of the neon o outdoor tubes The neon tubes need wires but the magic lI light ht has no wires and the crystal globes could he be carried from one place to another and set down where one wants It This Tills magic wireless light utilizes the principle pie of ot the ordinary electric where by pressing a button a current of electricity Is sent through a II coil con which repeatedly pulls a hammer hammer ham ham- mer that rings the bell r Scientists discovered that In the neighborhood of a rapidly changing magnetic field electrons In a gas- gas charged bulb started first one way and then another thus producing light The wireless light can be used only in pr proximity ty to changing magnetic coils colls For home lighting these coils colis would be placed In walls and they could be started agitating by pressing a button Just as the doorbell Is made to ring This principle of ot magnetic coils colls Is used to make a robot work In tho United States gov government assay office In New city That robot literally picks gold out of the air A con considerable quantity of gold formerly for for- merly was lost In the fumes that pass passed d off orr during the smelting process la is the assay office Now Kow these fumes are forced to rise between two metal plates These plates are charged with a high voltage electric current The gold particles In the fumes become electrified and settle on the near-by near electrodes Then they are shaken Into a collecting chamber below Hundreds of or o ounces or of gold goia worm worth many thousands of dollars have been recovered In this way by the robot Another magnetic robot now used by railroads detects broken rails and prevents accidents II The robot is housed on a small car resembling a handcar that Is towed slowly over the rails As It passes along the rails it sends an electric I current through the rails directly be- be I neaUl the c car r. r When a break In a rail Is encountered encountered the current Is is Interrupted and I the robot squirts a dab of paint on on- the spot where the bre break k Is Indi Indi- I This device detects flaws of or so so minute min min- minute ute a nature that they could not he human buman Countless Countless Countless' s seen b by t the eye railroad accidents have ave been av averted by the use of the robot The The magic light Is helping to perfect perfect per per- television that remarkable device device device de de- de- de vice that brings pictures of ot actual events along with sound over the radio Scientists have pro progressed so that six-foot six screens have far In this replaced the Inch fourteen-Inch screens ofa of a n short time ago and ond many more per perSons per persons can see the radio talkies sons IOns now and movies than formerly With ft a development of the new magic light that way two-way television It Is predicted will be speeded Demonstrations already al al showing both ready have been made conversation parties to o a telephone and It will n not t be he long say scientists are ore the you person before you o can see talking to over the telephone You also will be seen though Newspaper Union n. n 1931 Western |
