Dolezalek, The Theory of the Lead Accumulator (London, 1906); Sir D.
It is only necessary to add to these results the facts illustrated by the following diffusion curves, in order to get a complete clue to the behaviour of an accumulator in active work.
Fig 9 The lead accumulator is subject to three kinds of local action.
Such an apparatus enables us to see easily how the accumulator works.
The electricaccumulator or secondary battery, one of the most useful appliances, is the result of electrolysis reversed.
The era of the large electric accumulator of the kind foreshadowed by Prof.
It is, however, now the rule that all acids and all samples of water used for the purpose must be carefully tested before adoption, and this practice, in itself, has greatly prolonged the average life of the accumulator cell.
High ridges and eminences of all kinds will in the future be selected as the sites of wind-power and accumulator plants.
How is a hydraulic accumulator constructed, and why is it necessary?
This tuning-fork resembles a large trembler blade, such as is used in the high-tension accumulator and coil ignition system upon motor cars.
Of course, if a high capacity accumulator can be obtained, such as that of the latest Edison Nickel type, the light may be left burning continuously.
When a very great pressure is required a differentialaccumulator (fig.
The engines pump into the accumulator cylinder till the ram is at the top of its stroke, when by a catch arrangement acting on the engine throttle valve the engines are stopped.
Pipes lead from the accumulator to each of the machines requiring to be driven, and do not require to be of large size, as the pressure is so great.
If the accumulator ram descends, in consequence of water being taken to work machinery, the engines immediately recommence working.
An accumulator of this kind used with riveting machines has d1 = 5(1/2) in.
As, however, the pumping engine replaces water as soon as it is drawn off, the working capacity of the accumulator is very much greater than this.
The pumping engines which supply the energy that is stored in the accumulator should be a pair coupled at right angles, so as to start in any position.
In the use of accumulators on shipboard for working gun gear or steering gear, the accumulator ram is loaded by springs, or by steam pressure acting on a piston much larger than the ram.
Tweddell found that an accumulator charged at 1250 lb.
Therefore the energy wasted in propelling the accumulator along with a ear does not amount to more than 20 per cent.
Several electric launches are now being constructed in London, and one in New York by the Electrical Accumulator Company.
The loop of the rope is made long enough to permit the accumulator to stretch to double or treble its length, but it is arrested far within its breaking point.
On a bight of this rope, between the block and the bitt, the accumulator was lashed.
The accumulator is so arranged as to overflow when it comes to its maximum height.
The weight on the scale and that on the accumulator is made to correspond, so that wires of a certain number or size can be quickly tested in quantities under exactly the same conditions, with only the movement of the lever.
The accumulator or secondary battery, c, is especially designed to store the energy in a small space, and with light weight, and so as to command an amount of energy representing the power necessary for a speed of 25 miles an hour or more.
The fact that the Gibbs-Helmholtz equation is found to apply also indicates that the lead accumulator is approximately reversible in the thermodynamic sense of the term.
The effective electromotive force of the common lead accumulator (q.
After this, the instruction RTJ RES1 causes the address of the first parameter to be placed in the accumulator anytime it is performed.
This brings into theaccumulator a word of one of the following types: 1.
The two-cell accumulator carried in a motor car gives a voltage (otherwise called electro-motive force = E.
When the revolution of D brings the wipe and contact together, current flows from the accumulator through switch S to the wipe; through the contact-piece to C; from C to M P and the induction coil; and back to the accumulator.
If you attach a wire to one terminal of the accumulator and brush the loose end rapidly across the other terminal, you will notice that a bright spark passes between the wire and the terminal.
Pincaffs and Mr. Lachlan of the Faure Accumulator Company composed the party, and at 3:25 the train pulled out of the Victoria Station for Brighton.
With regard to expense, it is claimed for the accumulator and the incandescent lamps that the expenditure would be decidedly less than on oil, while, as to the comparative value of the two there is no room for difference of opinion.
By this means enough energy could be supplied to the incandescent lamps, but in any case the accumulator would be necessary to act as a reservoir when the train was not in motion.
The accumulator is arranged to control the throttle valve of the steam pumping engine so that when the plunger of the accumulator reaches a predetermined height the stream is cut off and the engine stops pumping.
One of the best forms of accumulator consists of a pile of perforated rubber disks, which receive the strain and become compressed in doing so.
In more recent ships a special derrick boom is rigged for this block, and a second accumulator is sometimes inserted between the topping lift by which this is raised and the end of the boom.
In the "Porcupine" and other early expeditions the accumulator was hung from the main yard arm, and the block through which the dredge rope ran suspended from it.
Mercury, its usefulness gone with the smashing of the accumulator trade, had been abandoned.
The perfectaccumulator had certainly been discovered.
We missed the atomic energy, but, sweet boy, what an accumulator we stubbed our toes on!
They are altogether too heavy, apart even from the accumulatoror source of electric energy, for the power derivable from them.
After five resounding back-fires the engine still failed to exhibit any signs of abiding vitality, although the accumulator had been reinforced by the magneto.
The engineer again hooks the accumulator rod to the engine throttle, and the whole is self-acting again until another weight is required.
The messy, troublesome accumulator will eventually give way to a neat little dynamo, which is driven by the engine and creates current for exploding the cylinder charges as the machine travels.
On land compressed-air installations include reservoirs of large size in which air can be stored till needed, and which take the place of the accumulator used with hydraulic power.
The load on the accumulator consists of a number of flat discs of metal, the first one about 14 inches thick and the others about 4 inches thick, the diameter being about 4 feet.
In lifting a ship, as she comes out of the water and gets heavier on the platform, additional discs are taken on by the accumulator ram as required.
In short, the accumulator is to hydraulic machinery what their bag is to bagpipes, or the air reservoir to an organ.
But with an accumulator there is always a supply of water under pressure at command, for as soon as the ram is nearly down, the engines are automatically started to pump it up again.
Edison is reported at work on an accumulator which will surpass all hitherto constructed, having a much longer life, and weighing very much less, power for power.
It is better than reflected light in operations on the nose and throat, and the portable accumulator and frontal photophore (Fig.
In all these methods the light is reflected, but the direct rays of the electric light can be used in a small lamp fixed on the forehead, and fed from an accumulator or direct from the street current through a suitable resistance.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "accumulator" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: battery; collector; connoisseur; farmer; magpie; miser
