The Clarks constructed successively, the 18-inch lens for Chicago, the 26-inch for Washington, the 30-inch for Pulkowa, the 36-inch for Lick and the 40-inch for Yerkes. Each in turn was the largest yet made, and each time the Clarks were called upon to surpass the world's record, which they themselves had already established. Have we at length reached the limit in size?
They were to be capable of driving 18-inch square piles of 70 feet in length into the silt of the Hamoaze. This first order for my pile-driver was a source of great pleasure to me. I had long contemplated this application of the power of the steam hammer. The machine had long been in full action in my "mind's eye," and now I was to see it in actual reality.
White 4-1/2 by 3/4 inch square-shouldered flooring: 1/4 square = 25 sq. feet. = 75 feet run. 3 by 1-1/2 inch battens = 88 feet run. 4 by 1-1/2 inch battens = 26 feet run. 3 by 2 inch battens = 27 feet run. 5 by 1-1/2 inch battens = 8 feet run. 2 by 1-1/2 inch battens = 21 feet run. There will also be required: Twelve 6-inch bolts and nuts. Two pairs 18-inch cross-garnet hinges. Two door bolts.
The second type was more lethal if one could get near enough to the enemy; it used an 18-inch length of electrical conduit to the end of which was welded a discarded gear, any old gear would do as long as it was sharp, heavy and pointy; in fact we were now armed with maces reminiscent of the middle ages and chronologically more in keeping with our Victorian surroundings.
To lay out 324 pounds at once on globes alone, useful as I acknowledge those articles to be, seems exceedingly profuse, when we have only about 3,000 pounds a year for all purposes of English education. One 12-inch or 18-inch globe for each school is quite enough; and we ought not, I think, to order sixteen such globes when we are about to establish only seven schools.
The submarine ran along at a speed of ten knots at a depth of forty feet and in almost no time at all had covered the mile from the entrance to where the men-of-war lay. "Now's the time," said Commander Nicholson. Quickly the torpedoes, 18-inch superheaters, were placed in the tubes. It only remained to arise, sight the enemy and fire.
An inference so contradictory to received ideas obtained little credit, until Peters found, in 1851, that the apparent anomalies in the movements of Sirius could be completely explained by an orbital revolution in a period of fifty years. Bessel's prevision was destined to be still more triumphantly vindicated. On the 31st of January, 1862, while in the act of trying a new 18-inch refractor, Mr.
The 10-1/2-inch Armstrong gun sent a round 150-pound shot, with 50 pounds of powder, through a 5-1/2-inch solid plate and its 9-inch teak backing and 5/8-inch iron lining, at 200 yards, and one out of four shots with the same charge through the Warrior target, namely, a 4-1/2-inch solid plate, 18-inch backing, and 5/8-inch lining.
She also mounted on the after-deck two 18-inch torpedo tubes, firing Whiteheads of an effective range of eight hundred yards at a speed of thirty knots, and carrying a charge of one hundred and seventy-one pounds of gun-cotton enough to destroy a battleship, if it happened to hit the right spot.
At Moneymore, Northern Ireland, a "level-headed and God fearing" citizen and his wife captured an 18-inch saucer by putting a headlock on it. They started to the local police station, but put the saucer down to climb over a hedge, and it went whirling off to the hinterlands of space.
