They discovered that each metal when in an incandescentstate exhibited through the prism certain distinctive brilliant lines.
He pointed out that metals, when rendered incandescentunder the flame of the blow-pipe, exhibited various tints.
While the first incandescent electric lighting plant was being prepared in New York City, Edison himself worked part of the time in the trenches, to be sure that the work would be properly done.
When Edison began working to produce an incandescent electric light for illuminating residences and small rooms, most of the scientists of England said that such a light could not be produced.
The incandescent electric light, for lighting residences and small rooms, came a little later as the invention of Edison.
Perseverance won, and the incandescent electric light became a reality about 1880.
These incandescent blocks crossed and struck each other, scattering still smaller fragments, some of which struck the projectile.
Their projectile, saturated with luminous gleams in the double irradiation of sun and moon, must have appeared like an incandescent globe.
It was like a moon, but an incandescent moon whose brilliancy was all the more intolerable as it cut sharply on the frightful darkness of space.
Twelve hundred melting-troughs were simultaneously opened and twelve hundred fiery serpents crept toward the central well, unrolling their incandescent curves.
The sulphur is thrown in only to improve the taste by pleasing the eye with the pretty bluish flame, that gambols on the surface of the incandescent fluid.
Instantly a flood of incandescent oil, bitumen and sulphur poured down like a wide sheet of flame upon the front ranks of the besiegers.
Like Rector's, it was also ornamented with a blaze of incandescent lights, held in handsome chandeliers.
At Broadway and Thirty-ninth Street was blazing, in incandescent fire, Carrie's name.
It was a place rather dingily lighted, the darkest portions having incandescent lights, filled with machines and work benches.
Incandescent lights, the reflection of their glow in polished glasses, and the shine of gilt upon the walls, combined into one tone of light which it requires minutes of complacent observation to separate and take particular note of.
It was bright and commodious, with a beveled mirror set in the wall at one end and incandescent lights arranged in three places.
On the ceilings were colored traceries with more gilt, leading to a center where spread a cluster of lights-incandescent globes mingled with glittering prisms and stucco tendrils of gilt.
The incandescent light sent a raw glare into the farthest corners of the large room, and just then a tiny wreath of white steam issued from the spout of the kettle.
His hand shook perceptibly as he mopped his forehead after sitting down, and he moved his chair uneasily twice because the incandescent light irritated his eyes.
As then, the fire was laid in the grate, but the man in black who sat in the shabby arm-chair had not put a match to the shavings, and the bright copper kettle on the movable hob shone coldly in the raw glare from the incandescent gaslight.
But he loitered near the stage entrance, keeping in the shadow on the other side of the alley, out of the range of the light from the incandescentglobe over the door.
The incandescent lights of ceiling and proscenium flashed up, showering radiance upon the vast surface of summer costumes and gay faces in the auditorium.
It flashed like an enormous meteor, like an incandescent flame.
There was no more night, for carbon and incandescent lamps had stabbed the night so that any hovel was brighter than the average day.
Here he entered into a long description of the pillar of "bottles," by which he evidently meant the incandescent globes.
He was gazing upon the incandescent globe-studded column, as in a trance, and again one of the electricians turned on the current and the shaft changed to living fire.
Incandescent lamps have also been invented by Maxim, Crooks, Fox Lane, and others; but they only differ in details of manufacture from those of Swan and Edison.
The experiment has been tried of breaking a lighted incandescent lamp in a vessel containing gunpowder, with perfect safety.
Not only has Mr. Edison invented an incandescent lamp, but he has also identified his name with a very complete system for producing the light on a large scale to suit both domestic and commercial requirements.
For domestic lighting we therefore come to quite a new departure in electric lamps; instead of the arc we have the incandescent regulator.
Each tree makes a fountain of flame, after which, for a moment, every needle shines like incandescent silver, while exquisite light columns of ashen green smoke float above.
The electric-light filament in the incandescent lamp is a much poorer conductor than the copper wire that leads up to it.
If I should set an emery-wheel to revolving and hold a piece of steel against it the piece of steel would become heated and incandescent particles would fly off, making a brilliant display of fireworks.
This core corresponds, electrically speaking, to the filament in an ordinaryincandescent lamp, only it is fourteen feet long and twenty-one inches in diameter.
It is suited to power, but not to incandescent lighting purposes, being similar in operation to a floating battery.
This is a constant voltage system and is used principally for incandescent lighting and electric motor circuits.
They are used on practically all incandescent lamp and electric motor circuits, and on some arc lamp circuits.
The talking sign consists of any desired number of monograms or units, in each of which any letter or figure can be formed by lighting certain combinations of incandescent lamps.
The simplest method of charging is from an incandescent light circuit, using lamps connected in parallel to reduce the voltage to that of the battery, the current being adjusted by varying the number of lamps in circuit.
It consists of a collection of metal compartments each arranged to receive an incandescent lamp.
Incandescent lamps cannot be made to stand a pressure much over 220 volts, and therefore have to be operated on low voltage systems.
This may be conveniently done by inserting in one of the charging leads an incandescent lamp which will pass the required quantity of current.
Incandescent lamps should never be used for resistance devices.
A and B are shown supplying two independent incandescent lighting circuits, each circuit receiving 3 amperes of current at a pressure of 110 volts.
What kind of incandescentlamp receptacle or wall socket is best adapted to exposed wiring?
Mr. Bullsom stood under the incandescent light and read aloud "The shooting-party at Enton yesterday consisted of the Marquis of Arranmore, the Hon.
B] We may conceive, therefore, that great masses of subterranean lava may remain in a red-hot or incandescent state in the volcanic foci for immense periods, and the process of refrigeration may be extremely gradual.
Because animal life existed upon the earth only in the secondary period, when a sediment of soil had been deposited by the rivers, and taken the place of the incandescent rocks of the primitive period.
Shiela laughed as the Seminole loomed up in the incandescent haze of the camp fire, buried in plumage.
And when a collision did happen it would be on a grand scale, and the result would be not an imperfect sun without planets, but an incandescent nebula, out of which, by condensation, a complete solar system would be evolved.
A far more effective means of dispersing the fragments and shattering them to pieces would be the expansive force of the enormous amount of incandescent gas almost instantaneously generated by the heat of collision.
The reason which he assigns for the incandescent globe settling down at a radius forty times that of the earth’s orbit is as follows: “The radius of a steady globular gaseous nebula of any homogeneous gas is 40 per cent.
Were this not so, the entire contents of the globe would gush from the incandescent center and fly off into surrounding space.
Thus, whenever we find a vent or open orifice, as in the craters of active volcanoes, the incandescent lava boils up and frequently overflows the top of the highest peak of the Andes.
With the explosion the cooled and darkened crust of the lava is removed, and the light of the incandescent liquid beneath is reflected from the cloud of vapor which overhangs the cone.
The base of it is a peculiar clay, found in Ceylon, which combines the indestructibility of asbestos with the non-conducting property of platinum; and having found the incandescent medium, he has next adapted it to the Bunsen burner.
Whoever sees the Welsbach incandescent light in operation will readily admit that it is the "coming light.
He had no doubt that the minds already at work on the incandescent light would seek out means for improving the burner.
At night a large mercury-vapor lamp in the center of the room, supplemented by a number of well-placed incandescent electric lights, gives ample illumination.
An incandescent light placed above the head at the front illuminates the chamber very well, and as a matter of fact the food-aperture is so placed that one can lie on the cot and actually look outdoors through one of the laboratory windows.
From and after that date incandescent electric lighting became commercially possible, and was brought to public notice chiefly by an electrical exhibition held at the Crystal Palace, near London, in 1882.
In lighting a private house or building, the first thing to be done is to settle the total number of incandescent lamps and their size, whether 32 c.
Hence a considerable variation in the light given by the incandescent lamps is observed, since the candle-power of carbon glow lamps varies as the fifth or sixth power of the voltage of supply, i.
The so-called subdivision of electric light by incandescent lighting lamps then engaged attention.
Practically the first of these furnaces was that of Despretz, in which the mixture to be heated was placed in a carbon tube rendered incandescent by the passage of a current through its substance from end to end.
The cable and incandescent lamp sections show that when the British manufacturers are allowed opportunities they are not slow to take advantage of them.
It had by that time become clear that the most suitable material for an incandescent lamp was carbon contained in a good vacuum, and St G.
In fact the invention of the incandescent lamp was incomplete--Edison's British master-patent was only filed in Great Britain in November 1879.
When the incandescent lamp became a commercial article, ship-lighting sets and installations for theatres and mansions constituted the major portion of the electrical work.
A deafening thunder assaulted our ears when to our horror the earth on which had stood the now burning town of Ogallala, rose a gigantic incandescent ball and shot like a meteor into the heavens.
If the beam of light passing through the slit has radiated from an incandescent solid or liquid body, or from a gas under high pressure, the coloured band or spectrum is found to contain all the colours indicated on Plate XIII.
The source of the sun's radiation cannot be found in the mere cooling of an incandescent mass.
They are, in fact, thrown up from the chromosphere like gigantic jets of incandescent material.
We know, for instance, that the bright lines of sodium vapour may be made so intensely bright that the spectrum of an incandescent lime-cylinder placed behind the sodium vapour does not reverse these lines.
Still more violent are the convulsions when, from the surface of the chromosphere, as from a mighty furnace, vast incandescent masses of gas are projected upwards.
