Large tanks of boiler-plate are used to receive the oil as it comes through the pipe-lines.
This is easily done in liming or measuring tanks of known capacity, into which the juice is run from the mill.
In many gardens open-air tanks have been fitted up with hot-water pipes running through them to keep the water sufficiently warm in severe weather.
In districts where the water is of a " hard nature," that is, contains bicarbonate of lime in solution, the interior of the boiler cylinders, tanks and pipes of a hot water system will become incrusted with a deposit of lime which is gradually precipitated as the water is heated to boiling point.
With " very hard " water this deposit may require removal every three months; in London it is usual to clean out the boiler every six months and the cylinders and tanks at longer intervals.

Should these tests prove satisfactory the core is served with jute yarn, coiled in water-tight tanks, and surrounded with salt water.
As the cable is sheathed it is stored in large water-tight tanks and kept at a nearly uniform temperature by means of water.
When the cable is to be laid it is transferred to a cable ship, provided with water-tight tanks similar to those used in the factory.
The cable is carefully coiled into the tanks in horizontal flakes, each of which is begun at the outside of the tank and coiled towards the centre.
Since then it has been discovered in other botanic gardens in various parts of Europe, its two most recent appearances being at Lyons (1901) and Munich (1905), occurring always in tanks in which the Victoria regia is cultivated, a fact which indicates that tropical South America is its original habitat.
In the same tanks a small hydroid, very similar to Microhydra, has been found, which bears medusa-buds and is probably the stock from which the medusa is budded.
The filtering works include 6 lime saturators, 2 mixing or softening tanks, 6 settling basins, 10 mechanical filters and 2 clear-water reservoirs.
The water cranes or towers which are placed at intervals along the railway to supply the engines with water require similar care in regard to the quality of the water laid on to them, as also to the water troughs, or track tanks as they are called in America, by which engines are able to pick up water without stopping.
These at first consisted of an ordinary truck on which were placed two wooden tub-like tanks, each holding about 2000 gallons; they were replaced in 1871 by the modern type of tank-car, constructed with a horizontal cylindrical tank of boiler plate.
Tanks of various types are employed in storing the oil, those at the wells being circular and usually made of wood, with a content of 250 barrels and upwards.
South of Biarritz on a ridge behind two lakes (or tanks) through Arcangues towards the Nive.
The liquid is now run into neutralizing tanks containing sodium carbonate, and, after settling, the supernatant liquid, termed "light liquor," is run through bag filters and then on to bone-char filters, which have been previously used for the "heavy liquor."
The plan usually adopted is to collect the latex in rectangular tanks or casks.
Large objects are suspended in the tanks by hooks or wires, care being taken to shift their position and so avoid wire-marks.

Water may be raised from mines by buckets, tanks or pumps.
Tanks operated by the main hoisting engines, and of capacities up to 50o gallons or more, are applicable under several conditions: (1) When the shaft is deep, the quantity of water insufficient to keep a pump in regular operation, and the hoisting engine not constantly employed in raising mineral, the tank is worked at intervals, being attached temporarily to the hoisting rope in place of the cage.
(2) For raising large volumes of water from deep shafts pairs of tanks are operated in balance in special shaft compartments by their own hoisting engine.
As the water level falls the tanks readily follow it while at work, whereas pumps must be lowered to new positions to keep within suction distance.
Self-acting tanks are occasionally built underneath the platforms of hoisting cages.
Tanks and pots are both used for melting the glass.
The boiling juice is run down into subsiding tanks, where it cools, and at the same time the albumen, which has been suddenly coagulated by momentary exposure to high temperature, falls to the bottom of the tank, carrying with it the vegetable and other matters which were in suspension in the juice.
The clear juice when it arrives at the top of the separator flows slowly over the level edges of, a cross canal and passes in a continuous stream to the service tanks of the evaporators or vacuum pan.
In some factories they are collected in suitable tanks, and steam is blown into them, which further coagulates the albuminous par Scums. tides.
After the juice has been defecated or purified by any of the means above mentioned it is sent to the evaporating apparatus, hereinafter described, where it is concentrated to 26° or 28° Beaume, and is then conducted in a continuous stream either into the service tanks of the vacuum pan, if dark sugars are required, or, if a better colour is wanted, into clarifiers.
The latter are circular or rectangular vessels, holding from 500 to 1500 gallons each, according to the capacity of the factory, and fitted with steam coils at the bottom and skimming troughs at the top. In them the syrup is quickly brought up to the boil and skimmed for about five minutes, when it is run off to the service tanks of the vacuum pans.
Apart from increased yield in sugar of good quality, we may sum up the advantages procurable from the use of Hatton defecators as follows: cold liming; heating gently to the temperature required to coagulate the albumen and not beyond it, whereby disturbance would ensue; the continuous separation of the scums; the gradual drying of the scums so as to make them ready for the fields, without carrying away juice or requiring treatment in filter presses; and the continuous supply of hot defecated juice to the evaporators, without the use of subsiding tanks or eliminators; and, finally, the saving in expenditure on plant, such as filter presses, &c., and wages.
They consist of tanks or cisterns fitted with " heads " from which a number of bags of specially woven cloth are suspended in a suitable manner, and into which the melted sugar or liquor to be filtered flows from the melting pans.
In a refinery in Nova Scotia a system has been introduced by which a travelling crane above the bag filters lifts up any head bodily with all its bags attached, and runs it to the mud and washing tanks at the end of the battery, while another similar crane drops another head, fitted with fresh bags, into the place of the one just removed.
The filtered liquors, being collected in the various service tanks according to their qualities, are drawn up into the vacuum pans and boiled to crystals.

The precipitation is carried out in tanks or vats made with"wooden sides and a cement bottom.
The supernatant liquid is led into settling tanks, where a further amount of "gold is deposited, r and is then filtered through sawdust or sand, the sawdust being afterwards burnt and the gold separated from the ashes and the sand treated in the chloridizing vat.
The liquors are run off from the vats to the electrolysing baths or precipitating tanks, and the leached ores are removed by means of doors in the sides of the vats into wagons.
Some 45 tanks were available, and owing to the absence of some of the corps artillery only 600 guns covered the advance.
Five hundred gun's and 45 tanks were detailed off to assist.

This was enhanced by the fact that only in certain sectors where the canal passed under the Bellicourt tunnel was it possible to employ tanks, of which some 130 were allotted to the left of the IX.
Some of the tanks are of great capacity; the Barwa Sagar, for instance, is 22 m.
It is then removed to lead-lined tanks and again washed with water and dried; the product obtained contains about 95% of anthraquinone.

The most famous is the Brazen Palace erected by King Datagamana about 164 B.C. The pokunas are bathing-tanks or tanks for the supply of drinking-water, which are scattered everywhere through the jungle.
It flourishes best in small tanks and ponds, in which the water is constantly changing and does not freeze; in such localities, and with a full supply of food, which consists of weeds, crumbs of bread, bran, worms, small crustaceans and insects, it attains to a length of from 6 to 12 in., breeding readily, sometimes at different times of the same year.
Nineveh was badly supplied with water for drinking; the inhabitants had to " turn their eyes to heaven for the rain," but Sennacherib conducted water by eighteen canals from the hills into the Husur and distributed its waters round the moats and into store tanks, or ponds, within the city.
Cylinders, tanks and independent boilers should be encased in a non-conducting material such as silicate cotton, thick felt or asbestos composition.
The tanks are nearly cylindrical in form and have a truncated cone fixed in the centre, as shown at C, fig.
Thus the dimensions of the largest glass tanks greatly exceed those of the largest steel furnaces; glass furnaces containing up to 250 tons of molten sible to work glass-tanks continuously for many months together; on the other hand, glass is not readily freed from foreign bodies that may become admixed with it, so that the absence of detachable particles is much more essential in glass than in steel melting.
