It was not until 1876, fifteen years after these principles had been enumerated, that Otto carried them into practical effect when he brought out a new type of engine, with compression before ignition, higher piston speed, more rapid expansion, and a general reduction of dimensions for a given power. Due to this achievement, the cycle above referred to has always been termed the "Otto" cycle.
Wall, 'is identically the same with the substances produced immediately above or below seams of coal, which have taken fire, and burnt for a length of time. There is lignite and other coaly matter enough in the rocks to have burnt like coal, if it had once been ignited; and the cause of ignition may be, as Mr. Wall suggests, the decomposition of pyrites, of which also there is enough around.
The walls and timbers of the houses at some distance from the conflagration were scorched and blistered with the heat, and completely prepared for ignition; overhead being a vast and momentarily increasing cloud of flame-coloured smoke, which spread all over the city, filling it as with a thick mist, while the glowing vault above looked, as Evelyn expresses it, "like the top of a burning oven."
Wrapping his blanket closely about him, he tried to dry the powder with the warmth of his naked flesh; but all his efforts were unavailing: the precious grains had totally lost the power of ignition. Reduced now to his prepared food, he determined to push on with all speed, and, before his supply should be exhausted, reach the settlements on the other side of the mountains.
The most important properties of these hydroxides, from a quantitative standpoint, other than those mentioned, are the following: All are precipitable by the hydroxides of sodium and potassium, but always inclose some of the precipitant, and should be reprecipitated with ammonium hydroxide before ignition to oxides.
Three of the American skippers had been quartered on the gunroom mess, and they were all at table. Snuff, snuff, smelled one, and another sniffled, "Gunpowder, I guess, and in a state of ignition." "Will you not send for the gunner, sir?" said the third. Splinter did not like it, I saw, and this quailed me. The captain's bell rang. "What smell of brimstone is that, steward?"
Ignition was by means of a high-tension magneto, and long induction pipes connected the-ends of the cylinders to the carburettor, the latter being placed underneath the engine. Lubrication was effected by spraying oil into the crank case by means of a pump, and a second pump circulated the cooling water.
Night after night, as Policeman Carew testified on the stand, he did not leave the shop till one and two in the morning. It was during this period that he perfected the improved ignition device for gas- engines, the royalties from which ultimately made him wealthy.
Some seeds will germinate when placed between pieces of ice and kept at a freezing temperature; and it is thought that, this method will afford an easy means of selecting varieties of seed which will bear a cold climate. The explosion in the coal mines at Jabin, Belgium, last February, was due to the ignition of fine coal powder suspended in the air.
And first, in the Laboratory, I connected a fuse-conductor with a huge tun of blasting-gelatine, and I set the fuse on the ground, timed for the midnight of the twelfth day thence; and after that I visited the Main Factory, the Carriage Department, the Ordnance Store Department, the Royal Artillery Barracks, and the Powder Magazines in the Marshes, traversing, as it seemed to me, miles of building; and in some I laid heaps of oil-saturated coal with an explosive in suitable spots on the ground-floor near wood-work, and in some an explosive alone: and all I timed for ignition at midnight of the twelfth day.
