A reflector of polished metal, especially one used in reflecting telescopes.
A condenser or reflector of light in optical apparatus; also, an illuminant.
That which hastens; especially, a stand or reflector used for confining the heat of the fire to meat while roasting before it.
Jumping up on a table, he fixed it to the top of the reflector over the gas-jet.
In the middle of the ceiling was a single gas-burner with a big reflector over it.
Stephen's mind halted by instinct, checked by the strange tone and the imagery and by the priest's face which seemed like an unlit lamp or a reflector hung in a false focus.
A lamp with a reflector hung on the japanned wall of the fireplace and by its light his aunt was reading the evening paper that lay on her knees.
Maston and Belfast announced that the projectile had just been seen in the gigantic reflector of Long's Peak, and also that it was held by lunar attraction, and was playing the part of under satellite to the lunar world.
According to the calculations of the Observatory of Cambridge, the tube of the new reflector would require to be 280 feet in length, and the object-glass sixteen feet in diameter.
The projectile had been detected, thanks to the gigantic reflector of Long's Peak!
In less than a year after the commencement of the works, towards the close of September, the giganticreflector rose into the air to a height of 280 feet.
A type of parabolic reflector now in use is shown in fig.
The following table gives the intensity of beam obtained by means of a type of reflector in general use: 21-in.
In this case the positive carbon is the lower one, and the lamp is carried in an inverted metallic reflector shield, so that the light is chiefly thrown up on the ceiling, whence it is diffused all round.
If it is not possible to obtain a northern light, which is best, a reflector of white paper or card may be used which must be sufficiently large and placed at an angle of about forty-five degrees to the transparency.
This instrument consisted of a reflector on the "Front-view" construction, with a speculum 4 feet in diameter and of 40 feet focal length.
Illustration: A reflector camp oven] The standard camp oven that has been used by generations of pioneers and campers is the Dutch oven.
A very convenient folding reflectoroven can be bought in aluminum for three or four dollars.
The reflector oven is the best for most cases if you can carry it conveniently.
Pour in a greased pan and bake in the reflector oven until when you test it by sticking a wooden splinter into it, the splinter will come out clean without any dough adhering to it.
Both the top and bottom of the reflector oven are on a slope and midway between is a steel baking pan held in place by grooves.
This reflector could be faced in any desired direction, and only a receiver located in that direction would respond to the message.
The reflector system being impracticable for long-distance work, Mr. Marconi experimented with tuning.
The wind sometimes blows a gale in Southern California, and I asked the manager what provision had been made for keeping this hugereflector from blowing away.
This done, the reflector follows the sun closely all day.
This reflector contains a prism which reflects the image of the object in view down through a system of lenses in the tube to another prism here at the bottom, where the observer sees it through an eyepiece and telescope lenses.
By turning this little crank,” the lieutenant continued, “I can revolve the reflector at the top of the tube.
Heavy weather had settled upon us and had blinded the little winking reflector on Monte Cristo Hill.
To aid the effect, a reflectorwas employed, and when the rays were directed to the clouds, they had the appearance of a huge comet, the reflector being the nucleus.
Accordingly, a number of scientific friends in that part of the world raised a monument with a suitable inscription, on the spot which had been occupied by the great twenty-foot reflectorat Feldhausen.
Another small reflector was inserted in the great tube sideways, so as to direct the gaze of the observer down upon the great reflector.
The little reflectorwhich he constructed, represented in the adjoining figure, is still preserved as one of the treasures of the Royal Society.
Footnote: The reflector was fractured by the explosion, but it did good service afterwards.
A beam of light was suffered to fall upon this reflector, and as the reflector followed the motion of the cube the images cast from its sides followed each other in succession, each describing a circle about thirty feet in diameter.
At the moment of totality the dark glass was to be removed, and a silver reflector pushed in, so as to get the maximum of light from the corona and prominences The time of totality was distributed as follows: 1.
Footnote: For charges of this weight the reflector is of moderate size, and may be employed without fear of fracture.
At the same time there is little doubt that the construction of a reflector of moderate size is easier than that of a corresponding refractor.
The essential part of the reflector is a slightly concave mirror of any metal which will bear a high polish.
Place this reflector in the prolongation of the optical axis, set the candle so that the light from the reflector shall be shown through the glass, and look through the opening.
Images of the reflector itself will then be seen in the object-glass, and if the adjustment is perfect, the reflectorcan be moved so that they will all come into coincidence together.
This is effected by having a reflector in the central part of the instrument, which throws the rays of light at right angles through the axis.
A more artistic instrument than a simple candle is a small concave reflector pierced through its centre, such as is used by physicians in examining the throat.
The tin reflector throws the heat of the fire back upon the meat; and, therefore, assists the process of roasting and helps to keep the kitchen cool.
If the tin reflector were painted, it would be utterly spoiled, because it would then absorb heat, and not reflect it at all.
Because glass is a good reflector of light; and the rays of the sun (striking against the window glass) are reflected, or thrown back.
We made several attempts to get the picture on page 260 but without success, until with a hand-mirror as a reflector we threw the rays of the sun on the bird.
Hastily he slipped from under his blankets and lighted the tin reflector lamp.
When Connie opened his eyes, daylight had vanished and Black Jack sat near the stove reading a paper-backed novel by the light of a tin reflector lamp.
Mrs. Draper has decided to send to Cambridge a 28 inch reflector and its mountings, and a 15 inch mirror, which is one of the most perfect reflectors constructed by Dr.
The 28 inch reflector will be used for the study of the spectra of the faint stars, and also for the fainter portions near the ends of the spectra of the brighter stars.
The property of the reflector needs no discussion other than to call attention to its enormous development.
Two of the most important parts of the organ have to do with the physical manipulation of light--the reflectorand the lens, respectively.
This spot is constant in position with reference to the sun in whatever position the fish be turned and is lost if the lens be dissected away and only the reflector left.
Where an intense light on a small area directly below the lamp is desired, a focusing reflector is used.
Where the area to be lighted by one lamp is smaller, the intensive reflector is used.
This reflector is applicable to general residence lighting, also uniform lighting of large areas where low ceilings or widely spaced outlets demand a wide distribution of light.
