Clerk Maxwell supposed two compartments, A and B, to be filled with gas at the same temperature, and to be separated by an ideal, infinitely thin partition containing a number of exceedingly small trap-doors, each of which could be opened or closed without any expenditure of energy.
In the United Kingdom, as in Europe generally, the vehicles used on passenger trains include firstclass carriages, second-class carriages, third-class carriages, composite carriages containing compartments for two or more classes of passengers, dining or restaurant carriages, sleeping carriages, mail carriages or travelling post offices, luggage brake vans, horse-boxes and carriage-trucks.
High; they weighed 3 or 4 tons, and were divided into three compartments holding six persons each, or eighteen in all.
Three years later that railway did away with second-class compartments and improved the third class to their level.
In the most approved type at the present time a passage runs along one side of the car, and off it open a number of transverse compartments or berths resembling ships' cabins, mostly for one person only, and each having a lavatory of its own with cold, and sometimes hot, water laid on.
To some extent cars divided into separate compartments are also in use in that country.
On the continent of Europe the typical sleeping car has transverse compartments with two berths, one placed above the other.
Long, and contained four compartments for first-class passengers or five for second or third class, carrying in the latter case fifty persons.
Long, holding seventy persons in seven compartments and weighing nearly 18 tons, and sixwheeled bogie composite carriages, 54 ft.
Long and weighing 23 tons, which included 3 first-class and .4 third-class compartments, with a cupboard for luggage, and held 58 passengers.
The next advance, introduced on the Great Western railway in 1892, was the adoption of corridor carriages having a passage along one side, off which the compartments open, and connected to each other by vestibules, so that it is possible to pass from one end of the train to the other.
For instance, fourwheeled bogie third-class corridor carriages employed on the Midland railway at the beginning of the 10th century weighed nearly 25 tons, and had bodies measuring 50 ft.; yet they held only 36 passengers, because not only had the number of compartments been reduced to six, as compared with seven in the somewhat shorter carriage of 1885, by the introduction of a lavatory at each end, but each compartment held only 6 persons, instead of 10, owing to the narrowing of its width by the corridor.
The buildings may be divided into five groups: (I) a large cistern in five compartments, each measuring 39 by 17 ft.; (2) habitations both for the owners and for slaves, and store-rooms; (3) baths; (4) habitations for slaves; (5) belvedere.
There remains one other important group, the so-called " kidney " cottons in which there are only long hairs, and the seed easily comes away clean as with " Sea Island," but, instead of each seed being separate, the whole group in each of the three compartments of the capsule is firmly united together in a more or less kidney-shaped mass.
It consists of five rectangular compartments, three on one side of the corridor FIG.
Two of the five compartments are supposed to have been assigned to male, and two to female worshippers, the fifth, at the extremity of the whole, being reserved for the altar and its ministers.
The walls of the compartments are occupied by arched sepulchral recesses, above and below which are tiers of ordinary graves or loculi.
These seven hells are subdivided into innumerable compartments corresponding to every species of sin, where the demons torture the poor deluded human beings who have suffered themselves to be led astray whilst on earth.
The size, shape and design of the cars depend on the size of the mine passage and of the hoisting compartments of the shafts; on whether the cars are to be trammed by hand or hauled in trains; whether they are loaded by shovel or by gravity from a chute; and whether they are to be hoisted to the surface or used only for underground transport.
At a few mines special man-cages are operated in separate compartments by their own engines for handling part of the men, and for tools, supplies, &c. For inclined shafts, where the mineral is hoisted in skips, the operation of raising and lowering men may not be so simple.
(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.
Two compartments of a shaft may be utilized for this purpose, but greater safety is ensured by two separate openings, as required by law in most mining countries.
13,336 of 1894) a rapidly rotating cathode is used in a chloride solution, a porous partition separating the tank into anode and cathode compartments, and the chlorine generated by electrolysis at the anode being recovered.
The Palazzo della Ragione, with its great hall on the upper floor, is reputed to have the largest roof unsupported by columns in Europe; the hall is nearly rectangular, its length 2672 ft., its breadth 89 ft., and its height 78 ft.; the walls are covered with symbolical paintings in fresco; the building stands upon arches, and the upper storey is surrounded by an open loggia, not unlike that which surrounds the basilica of Vicenza; the Palazzo was begun in 1172 and finished in 1219; in 1306 Fra Giovanni, an Augustinian friar, covered the whole with one roof; originally there were three roofs, spanning the three chambers into which the hall was at first divided; the internal partition walls remained till the fire of 1420, when the Venetian architects who undertook the restoration removed them, throwing all three compartments into one and forming the present great hall.
Two of the five compartments into which it is divided by walls of deeply striated volcanic ash are constantly emitting steam, while a new vent displaying great activity has been opened at the base of the cone on the south side.
In 1665, physicist Robert Hooke pointed a microscope at a piece of cork and noticed many small compartments he called "cells."
