The brain of the scientist is rather a sort of electrical accumulator, which feels and assimilates the vibrations and heart-beats of life, its splendor and its shame, and derives therefrom the conviction that it must of necessity provide for definite social wants.

He was truly the electric accumulator of his time, who gathered from its atmosphere the presage of the coming revolution, the stirring of the human conscience.

This accumulator is of the Plante type, and is modified so as to obtain a more rapid formation, a larger surface, and a symmetrical distance of the plates from each other.

The plates are made of four different sizes: No. 1, 19 of which serve for an accumulator of 1 square meter; No. 2, 21, 25, or 29 of which serve for accumulators of 2, 3, and 4 square meters; No. 3, which with 21, 25, or 29 plates composes accumulators of 5, 6, and 7 square meters; and No. 4, which with 21, 23, 25, 27 or 29 plates forms accumulators of 8, 9, 10, 11, and 12 square meters.

If it is wished to lift the accumulator from its chest for any verification, hooks passing between the plates seize hold of the rods, and thanks to the rigidity of the antimony lead, they effect the removal of the apparatus without bending the rods in the least.

The weight of the accumulator bears entirely upon the back of the combs, which are all placed back downward, and the number of which varies according to the size of the plates.

Small combs of wood clasp the plates at their extremities, and make the entire accumulator quite compact and manageable.

For a "No. 10" accumulator we have an active surface of 10 square meters, a charging current of 100 amperes, and on discharging a current of 200 amperes.

It will be seen that to increase the thickness of the sheet of lead merely augments the duration of the accumulator, without affecting its capacity or its manner of charging and discharging.

The next four pointsi.e., the rapidity of charge; the yield, much greater than that of any other system in proportion to its surface; its small weight in comparison with its yield; and its capacity, which for an equal weight is greater than that of any other accumulator.

In his experiments in September, 1885, Dr. D'Arsonval obtained with an accumulator of 2 square meters of surface: Useful capacity 40 ampere hours.

The total capacity of an accumulator having exactly 1¾ meters of surface has become 87 ampere hours, which if referred to an accumulator of 2 square meters of surface, would give the following results: Useful weight of lead per sq. meter 5½ kilos.

On September 8, 1885, Dr. D'Arsonval, professor at the College of France, wrote as follows: "The Montaud accumulator is of the Plante type, and is extremely well conceived from a mechanical point of view.

My opinion, therefore, is that the Montaud accumulator is very practical, that it is a great improvement on the Plante type, and that it can compete successfully with the other systems in use.

Let us take another example from the domain of electricity, in order to better show the utility of the apparatus; let us suppose that we have a curve representing the discharge of a pile or of an accumulator.

ARMSTRONG, WILLIAM GEORGE, LORD, born at Newcastle, produced the hydraulic accumulator and the hydraulic crane, established the Elswick engine works in the suburbs of his native city, devoted his attention to the improvement of heavy ordnance, invented the Armstrong gun, which he got the Government to adopt, knighted in 1858, and in 1887 raised to the peerage; b. 1810.

45 HYDRAULIC MANGLE] A heavy hydraulic mangle with its accumulator and made by Messrs. Urquhart, Lindsay & Co., Ltd., Dundee, is illustrated in Fig.

While the operation of mangling is proceeding, the rollers move first in one direction and then in the other direction, and this change of direction is accomplished automatically by mechanism situated between the accumulator and the helical-toothed gearing seen at the far end of the mangle.

The high structure on the left is the accumulator, the manipulation of this and the number of wide weights which are ingeniously brought into action to act on the plunger determine the pressure which is applied to the fabrics between the bowls or rollers.

INDEX ACCUMULATOR Assorting jute fibre.

This will be supplied by a single cylinder engine of 900 millimeters blast, and 786 millimeters steam piston, diameter 786 millimeters, stroke making fifty revolutions per minute, which is also to work a Root blower and the accumulator pumps.

The accumulator is intended to work at 300 lb. pressure.

The cost of the plant, including one of each of the following items, converter, converter truck, blowing engine, accumulator, ingot crane, centesimal weighing machine, and accumulator pump, is estimated at £2,050 to £2,100; and that of the steam boiler, £325.
