... is worked by clockwork inclosed between two disks, and would rotate continuously were it not for the catch, G, working in and out of the cogs. Through this catch, G, the wheel is dependent on the movement of electro-magnet. This cogged wheel is a double one, consisting of two wheels coupled together, exactly similar one with the other, and so fixed that the cogs ...

... early form, the magneto-generator consisted of the arrangement shown in Fig. 17, wherein a permanent magnet can rotate on an axis before an electromagnet having soft iron cores and a winding. Reversals of magnetism produce current in alternately reversing half-cycles, one complete rotation of the magnet producing one such ...

... that motives exist adequate to decide the will; even though it may not always be conscious of them. Science has proved that forces, sensible and occult, physical and metaphysical, simple and complex, surround, traverse, vibrate, rotate, repel, attract, without stop; that man's senses are conscious of few, and only in a partial degree; but that, from the beginning of organic existence, his consciousness has been induced, expanded, trained in the lines of his sensitiveness; and that the rise of his faculties from a lower ...

In another group, represented by Opuntia (fig. 1), the flowers are rotate, that is to say, the long tube is replaced by a very short one. At the base of the tube, in both groups, the ovary becomes developed into a fleshy (often edible) fruit, that produced by the Opuntia being known as the prickly ...

... four raised spaces in the bore of the rifle between the grooves. These lands grip the bullet as it passes through the bore and rotate it to the right about the longer axis. This rotation serves to prevent tumbling and keeps the bullet accurately on its course. This spinning of the bullet also causes it to drift slightly to the right as it passes through the air. The same effect is produced ...

... at a predetermined rate of speed. We can project them, divide them up in a few or an infinite number of pieces, accordingly as we break them or grind them to powder; we can twist bodies or make them rotate, modify, compress, expand, or extend them. The whole science, sir, rests upon ...

... projectile. The powder gas pressure expanded the rim of the gas check into the rifling grooves and prevented the escape of gas; it also firmly fixed the gas check to the projectile, thus causing it to rotate. A more regular and efficient action of the powder gas was thus ensured, with a corresponding greater range and an improvement in accuracy. With the earlier Armstrong (R.B.L.) guns the projectiles were coated with lead (the late Lord Armstrong's system), the lead being forced through ...

... less than three hundred thousand years ago. First of all our planet hung in the form of vapour, and drifted with millions of other similar clouds through space; then the vapour became liquid; then the globular form was assumed, and the flying ball began to rotate round the great attracting body. We cannot tell how living forms first came on earth; for they could not arise by spontaneous generation, in spite of all that Dr. Bastian may say. Of the coming of life we can say nothing—rather an odd admission, ...

Then both the shafts at the points of the arms of the V will rotate equally. [Footnote: See diagram of mechanical Telautograph, and of bow drill. In the latter, in ordinary use, the stick and string; rotate the spool. Rotating the spool will, in turn, move the stick and string, and this is its action in the pen-arms of the Telautograph.] The number of impulses ...

If I cut out a rectangular piece of paper from this sheet and mount it on a pivot or shaft at A B, I can rotate it through 180 degrees, just like a child's teeter-totter, so that X will be where Y originally was. That is in two dimensions. Now, simply add one dimension all the way round and you will have ...

... greatest freedom, and, moreover, the wrist may be turned and the hand laid on its back, its palm, its edge, or at almost any conceivable angle. This is a very convenient contrivance for man, but it would be a great misfortune for our avian friends if their wings would rotate so readily; for in that case they would not have sufficient rigidity to answer the purposes of flight, but would be twisted into every position by the assaults of the air currents. Besides, even in ordinary flight it would require a ...

... Joseph's dream, our relatives revolve and upon which they help to shed an added lustre. Our Ptolemaic theory of society is necessitated by our tenacity to the personal standpoint. This fixed idea of ours causes all else seemingly to rotate about it. Such an egoistic conception is quite foreign to our longitudinal antipodes. However much appearances may agree, the fundamental principles upon which family consideration is based are widely different in the two hemispheres. For the ...

These facts, he said, indicate indisputably a common origin for all the members of the solar system. He expressed the belief that the materials now composing the solar system were ...

... sternomastoid muscle bulged at the angle of the jaw, and was flaccid, and his "Adam's apple" was on a level with the chin. Sensation in the upper extremities was partially restored, and, although numb, he now had power of movement in the arms and hands, but could not rotate his neck. A diagnosis of cervical dislocation was made, and violent extension, with oscillation forward and backward, was practiced, and the abnormal appearance subsided at once. No crepitus was noticed.

If we are challenged as to why we believe that it will continue to rise as heretofore, we may appeal to the laws of motion: the earth, we shall say, is a freely rotating body, and such bodies do not cease to rotate unless something interferes from outside, and there is nothing outside to interfere with the earth between now and to-morrow. Of course it might be doubted whether we are quite certain that there is nothing outside to interfere, but this is not the interesting doubt. The interesting ...

In using the circle-pencil and circle-pen it will be found more convenient to rotate it in the direction of the arrow in Figure 34.

Commander Cameron, the African explorer, mentioned that arrow-heads of the same shape as many exhibited by Mr. Knowles were in use in various African tribes. One shape was formed so as to cause the arrow to rotate, and was principally used for shooting game at long distances. The shape of the arrows varied according to the taste of the makers; in one district there were ...

Ptolemy did not know this, and consequently he came to the conclusion that the earth did not rotate, and that, therefore, notwithstanding the tremendous improbability of so mighty an object as the celestial sphere spinning round once in every twenty-four hours, there was no course open except to believe that this ...

... elastic and the padding deep and soft. Being swiveled at top and bottom, they could swing around so that deceleration as well as acceleration was relieved. For this reason the controls had been altered so that the flexible support in which Hart was suspended could rotate about their pedestal, thus allowing for their operation by the pilot either when accelerating or decelerating. How he could control the muscles of his arms and hands under the extreme conditions is still a mystery to me, however, and George agrees with me in ...

These whorls are discs of wood, stone, clay, or metal which keep the spindle steady and promote its rotation. The process in effect is precisely ...

The motion of its shell had alone been stopped; the internal part was still rotating and this compelled the shell to follow it. Owing to this cause, when we handle the two eggs, the one feels "quick" and the other ...

They seem to think that the land contains an inexhaustible supply of plant food. Another cause is the failure of the farmer to rotate his crop. There are farms being cultivated in the South today where the same piece of land has been planted in cotton every year for forty or fifty years. Forty years ago, this same land would yield from one bale to one and a half per acre. And ...
