"Actinic" Quotes from Famous Books
 ... out of the sky with a terrific velocity. Tracer bullets sprayed all around it. Some could be seen to ricochet off its sides. Flashings came from the alien craft. They were not explosions from guns. They were lurid, actinic, smokeless blasts of pure light. The Thing seemed to be made of polished metal. It dodged, trying to approach the transport. The fighters lunged to prevent it. The ghastly game of interception seemed to rush here and there ...

... own wife, a man may seem in the gall of bitterness and the bond of iniquity, when "larger, other eyes than ours" may be watching with delight the germ of righteousness swell within the inclosing husk of evil. Sooner might the man of science detect the first moment of actinic impact, and the simultaneously following change in the hitherto slumbering acorn, than the watcher of humanity make himself aware of the first movement of repentance. The influences now for some time operative upon her, were the more ...

... cover one inch in length. There is only a little over half an octave that the eye can appreciate as light, and then all is darkness; but we can still go on further by the help of Science: beyond the violet we have the actinic or chemical rays, which are used in photography, and which enable us to trace the frequencies for a further two octaves. Beyond this we cannot pierce with our present knowledge; but there may be, and probably are, ...

... most approved antiseptic manner; his gums were swabed with boracic acid, and he was fed from a sterilized bottle on Pasteurized milk, and tucked up in a crib with carbolized sheets, and placed close to the window where he could bask in actinic rays, and inhale ozone to his heart's content. Thus the passer-by could see at a glance that the good work had begun to ...

... with aniline brown, and, after drying, to wash it with turpentine oil which dissolves the lithographic ink without altering the aniline. The lines appear then white on a brown ground impervious to light (that is, non-actinic). The design is thus transformed into a negative, and can yield positive impressions with paper sensitized with silver salts, the ferriprussiate or the bichromate of potash. The lithographic ink should be very black ...
— Photographic Reproduction Processes • P.C. Duchochois
... "rice" paper also there manufactured. It is easily washed away unless bichromate of ammonium or potassium in minute quantities be added to it, and then if the paper on which it appears be exposed for a short time to the action of the actinic rays of sunlight, this gummy compound will be rendered insoluble and cannot be removed with any fluid, chemical or otherwise. It possesses also great advantages in drawing, since it acts as a paint, and will give any degree of blackness according ...

... spectrum, so in love: beyond and intermingled with the visible rays of passion are numerous actinic but invisible rays of affection, invisible to careless spectators, but known and felt by the recipients. These, too, must be introduced if the connubial domicile is to be warmed ...

... yellow rays. It emits virtually no red rays, and, therefore, red objects appear devoid of red. The human face appears ghastly under this light and it distorts colors in general. However, it possesses the advantages of high efficiency, of reasonably low brightness, of high actinic value, and of revealing detail clearly. Various attempts have been made to improve the color of the light by adding red rays. Reflectors of a fluorescent red dye have been used with some success, but such a method reduces the luminous efficiency of the lamp considerably. ...
— Artificial Light - Its Influence upon Civilization • M. Luckiesh
... the profits of the discovery. He would fain have photographed the interior of the cavern but was reluctantly forced to forgo the gratification of this desire, from inability to produce artificial light of the necessary actinic value. But, to compensate for this disappointment, he spent no less than three days in the cavern, making sketches ...
— In Search of El Dorado • Harry Collingwood
... marine-glue gives the bitumen greater pliancy, and prevents it from scaling off when rubbed, particularly when the plate is retouched with a dry point. These bitumen plates are so thoroughly opaque to the penetration of the actinic rays, that the printing-frame may be left for any time in full sunlight without any fear of fog being produced on the zinc plate from which the prints ...

... half turned. There was a soundless flash beside me, a tiny level beam leaped down the corridor—that horribly intense actinic white beam. It struck the guard, and his figure fell forward in the grille doorway. When we reached him, there was but a crumpled heap of black and white garments enveloping a bleached ...

... 1852 he began to carry out electrolytical decompositions by the aid of the battery. By means of a very ingenious arrangement he obtained magnesium for the first time in the metallic state, and studied its chemical and physical properties, among other things demonstrating the brilliance and high actinic qualities of the flame it gives when burnt in air. From 1855 to 1863 he published with Roscoe a series of investigations on photochemical measurements, which W. Ostwald has called the "classical example for all future researches in physical chemistry." Perhaps the ...

... these facts that the heat rays, the light rays, and the chemical rays were different in quality; and some of the late books treating upon this very subject represent a solar spectrum as being made up of a heat spectrum, a light spectrum, and an actinic or chemical spectrum, and the idea has often been made to do duty as an analogy in trinitarian theology; nevertheless it is utterly wrong and misleading. There is no such thing as an actinic spectrum; that is, there are no such rays ...

... reasonable, natural, and not harder to believe than that the disease germ, a creature of darkness, perishes when exposed to the light of the great sun—a new revelation of profane science which no one doubts. He reminds us that the actinic ray, shining upon lupus, cures it—a horrible disease which was incurable fifteen years ago, and had been incurable for ten million years before; that this wonder, unbelievable by the physicians at first, is believed by them ...
— Innocents abroad • Mark Twain
... interesting to note the large amount of blue and violet light in the acetylene flame, for these are the colours which are chiefly concerned in photography; and it is to their prominence that acetylene has been found to be so very actinic. It is also interesting to note that an addition of air to acetylene tends to make the light even more like that of the sun by reducing the proportion of red and blue rays to nearer the ...
