 ... the direction of the shock is indicated. But, in falling, it causes the lever, F, to tilt, and this brings about an electric contact between the screw, h, and the column, n, which sends a current into the electro, E, so that the armature of the latter is attracted. In its position of rest this armature holds a series of parts, S, A, L, which have the effect of stopping the pendulum of a clock placed upon the same apparatus. At the moment, then, that the armature is attracted ...

... the apparatus employed in this historic research. Note its extreme simplicity. In one of his first successful experiments he wraps a coil of insulated wire around the soft iron bar that forms the armature or keeper of a permanent magnet of the horse-shoe type, and connects the ends of this coil to a galvanometer. He discovers that whenever the armature is placed against the magnet poles, and is therefore being rendered magnetic by contact therewith, the deflection of the ...

... recommends for armature work a compound made by boiling pure linseed oil at about 200 degrees with 1/2 per cent. of borate of manganese, the boiling being continued for several hours, or until the oil begins to thicken. An advantage ...

... magnificent preparations that were made for the reception of so great an Emperor, Domenico fashioned a horse eight braccia high and in full relief, all of paste-board and hollow within. The weight of that horse was supported by an armature of iron, and upon it was the statue of the Emperor, armed in the ancient fashion, with a sword in his hand. And below it were three large figures—vanquished by him, as it were—which also supported part of the weight, the horse being in the ...

... have constituted a horny beak. Like most of the other Jurassic Pterosaurs, Rhamphorhynchus (fig. 179) does not seem to have been much bigger than a pigeon, in this respect falling far below the giant "Dragons" of the Cretaceous period. It differed from its relatives, not only in the armature of the mouth, but also in the fact that the tail was of considerable length. With regard to its habits and mode of life, Professor Phillips remarks that, "gifted with ample means of flight, able at least to perch on rocks and scuffle along the shore, perhaps competent to dive, though ...

... to the telephone, she removed the receiver from the hook and let it hang at the full length of the cord. In the dead silence the small voice of Central was clearly articulate: "What number? Hello, what number?"—followed by the grumbling of the armature as the operator tried fruitlessly to ring the disconnected bell. The girl smiled faintly, aware that there would now be no interruption ...

... form, it is plain that a spiral of sheet-metal wound round the barrel will offer the most convenient type of structure for stability and cheapness combined. At the end of this long barrel will be fixed the dynamo, the armature of which is virtually a part of the barrel itself, while the magnets are placed in convenient positions on the supporting uprights. From the generating dynamo the current is conveyed directly to the storage batteries, and these ...

... to feed sixty lamps of 16 candle power each, the current being 60 amperes at 50 volts. The armature is of the drum type. The peculiar feature of it is that grooves are planed in the laminated core from end to end, and in these grooves the conductors, which are of ribbon section, are laid. Slips of insulating material are laid between ...

... illuminate this trough, but not be seen by a person seated some distance in front of the window in the next room. A needle (D) was hung on a pivot behind the cardboard, so that its point could move along the bright trough in either direction; and on the needle was put the armature (A) of an electro-magnet which, when a current passed, would be drawn instantly to the magnet (E), and so stop the needle exactly at the point which it had then reached. A clock motor (Cm) was arranged in such a way as to carry the needle ...

... bear is a much more compact animal than either the black or polar species: his ears are larger, his arms stouter, and his aspect fiercer. His teeth are sharp and strong; but that which his enemies most dread is the armature of his paws. The paws themselves are so large, as frequently to leave in the mud a track of twelve inches in length, by eight in breadth; and from the extremities of these formidable fists protrude horn-like claws full six inches long! Of course, we are speaking ...
