Two banks of a dozen electric lights as big as street arc lamps, and just as powerful, had been strung across the ceiling. These, by means of reflectors, were made to flood the far end of the room, "the stage," with a steady white light.
He advocated the use of automatic sprinklers in the case of fire, the establishment of parabolic reflectors for concentration of sound, and the further prosecution of experiments by Professor Bell in establishing communication between vessels some distance apart by means of interrupted electrical currents.
'About three years ago, in the course of a conversational discussion with Sir David Brewster upon the merits of some ingenious suggestions by the latter, in his article on Optics in the "Edinburgh Encyclopædia," p. 644, for improvements in Newtonian reflectors, Sir John Herschel adverted to the convenient simplicity of the old astronomical telescopes that were without tubes, and the object-glass of which, placed upon a high pole, threw the focal image to a distance of 150 and even 200 feet.
Modern astronomy may be said to have been thereby rendered possible. Refractors have always been found better suited than reflectors to the ordinary work of observatories. They are, so to speak, of a more robust, as well as of a more plastic nature. They suffer less from vicissitudes of temperature and climate.
An archway was the entrance to the establishment and many a bullet hole within its shadow testified to the dark deeds that had happened there. Now, as on every night, the place was ablaze with light. Big oil lamps by the score, backed by polished reflectors, illumined the interior.
We have seen already something of the vociferous thoroughness of the man, upon the cleaning of lamps and the polishing of reflectors. In building, in road-making, in the construction of bridges, in every detail and byway of his employments, he pursued the same ideal.
This mode of lighting and reflection may be adapted to a Brunton otoscope, utilized for examining other natural cavities, such as the nose, pharynx, etc. Elliptical reflectors do not appear to have been employed up to the present. By C. H. HUGHES, M.D.
"If the ship was hove to and these things just drifted in gradually " "Oh, I see. That wouldn't activate the reflectors. Then, if we keep moving ourselves " "That," said the Commissioner, "was what I had in mind." Trigger couldn't keep from staring at the subspace station. It was unbelievable.
Here I found various articles of use in a household, some of which were new to me. It is very likely that I could have found most of them in our own Boston Cornhill, but one often overlooks things at home which at once arrest his attention when he sees them in a strange place. I saw great numbers of illuminating contrivances, some of which pleased me by their arrangement of reflectors.
The reflectors are here also ranged upon a frame, with faces which are made to revolve with considerable rapidity; and the light thus emerging from a partial state of darkness exhibits a momentary flash, resembling a star of the first magnitude, and thereby produces a very striking effect.
