There were arms of the chase and of war; fishing appliances; electric lights; instruments of observation, compasses, and sextants for checking the course, thermometers for studying the temperature, different barometers, some for estimating the heights attained, others for indicating the variations of atmospheric pressure; a storm-glass for forecasting tempests; a small library; a portable printing press; a field-piece mounted on a pivot; breech loading and throwing a three-inch shell; a supply of powder, bullets, dynamite cartridges; a cooking-stove, warmed by currents from the accumulators; a stock of preserves, meats and vegetables sufficient to last for months.
During the day the work on the fore screw had been actively carried on, but it had had to be taken on board to adjust the twisted blades. Of the piles and accumulators and the machinery that drove the ship nothing was damaged. When night fell Robur and his men knocked off work. The fore propeller not been got into place, and to finish it would take another three hours.
"You couldn't squeeze another frank into our accumulators with a proof-bar, and since they're sending us all the power we want to draw, we won't need to touch our batteries or tap our own beam until we're almost to Jupiter. To cap the climax, what it takes to make big medicine on those spherical friends of ours, we've got.
Driven as they were by the millions upon millions of horsepower stored in the accumulators of the Sirius they formed a coruscating spherical shell of intolerable energy all around the enemy vessel, but even their prodigious force was held at bay by the powerful defensive screens of the smaller space-ship.
"I do not pretend to be anything more than an integral portion of an accepted and not altogether mushroom institution." "Quite so," said the Waters. "Then go round hard " "To what end?" asked the Wheel. "Till a big box of tanks in your house begins to fizz and fume gassing is the proper word." "It would be," said the Cat, sniffing. "That will show that your accumulators are full.
For the purpose of comparison, let us now employ the man who would otherwise clean and prepare the primary cells, at engine driving. We let him attend to a six horse power steam engine, boiler, and dynamo machine for charging 50 accumulators, each of a capacity of 370 ampere hours, or one horse power hour.
Dredging in 150 fathoms is very hard work, if it has to be carried on by manual labour; but by the use of the donkey-engine to supply power, and of the contrivances known as "accumulators," to diminish the risk of snapping the dredge rope by the rolling and pitching of the vessel, the dredge has been worked deeper and deeper, until at last, on the 22nd of July, 1869, H.M.S. Porcupine being in the Bay of Biscay, Captain Calver, her commander, performed the unprecedented feat of dredging in 2,435 fathoms, or 14,610 feet, a depth nearly equal to the height of Mont Blanc.
The carburets of hydrogen which separate in a liquid state through the effect of the compression of the gas are retained in a cylindrical receptacle, V, which is located between the pump and the accumulators, T.
"And then some. We've got just two methods of getting away from here one is to get in touch with Brandon, so that he'll come after us; the other is to recharge our accumulators and try to make it under our own power. Either course will need power and lots of it...." "I never thought of going back in the 'Hope. Suppose we could?"
In the third, near the screw, was the electric motor which transformed into movement the current of the accumulators. Under all this, beneath the floor, from end to end, were immense water ballasts, which were capable of being emptied or filled in a few seconds by electric machines, in order to carry the vessel up or down.
