A bottle mould rises and envelops the mass of molten glass.
It is by this time mere vegetable mould and undistinguishable pond shore, through which rushes and flags have pushed up.
Rubber mixed in the usual way with about WA of sulphur is now softened by heat, forced into the mould, and retained there by pressure during the operation of curing, which is usually effected in an iron box heated over a gas burner to 140° C.
A non-spherical form can only be produced by blowing the hollow bulb into a mould of the required shape.
Small, of Berwickshire, brought out a plough in which beam and handle were of wrought iron, the mould-board of cast iron.
The working parts of the plough are the coulter, the share, and the breast or mould-board.
I know that she has remarkable powers, and I believe that I shall be able to develop and mould them.
But it has a value of its own inasmuch as it illustrates the permanent tendencies which mould the history of the Jews.
In the latter part of his stay at Auxonne (June 1788 - September 1789) occurred the first events of the Revolution which was destined to mould anew his ideas and his career.
The soil is composed of red ferruginous kankar, with a stratum of clay in the more elevated parts, covered by a thin layer of vegetable mould, or by recent alluvial deposits.
The surface soil of Berar is to a great extent a rich black vegetable mould; and where this surface soil does not exist, there are muram and trap with a shallow upper crust of inferior light soil.
He did more than any one to mould the minds * of the rising generation, and he carried them with him even in his violent attacks on all opinions and all parties which appeared in any way to be injurious to the rising power of Germany.
The blower places the glass in the mould, closes the mould by pressing a lever with his foot, and either blows down the blowing iron or attaches it to a tube connected with a supply of compressed air.
When the air has forced the glass to take the form of the mould, the mould is opened and the blower gives the blowing iron with the bottle attached to it to the " wetter off."
A plunger is forced upwards into the glass in the neck-mould and forms the neck.
Compressed air admitted through the plunger forces the molten glass to take the form of the bottle mould and completes the bottle.
As soon as a blowing iron is in connexion with an air jet, the sections of the mould close upon the molten glass, and the compressed air forces the glass to take the form of the mould.
The mass of glass, yielding, to its own weight and the pressure of air or steam, sinks downwards and adapts itself to any mould or receptacle beneath it.
The mould is in two, pieces hinged together; it is heated and the inner surface is rubbed over with finely powdered plumbago.
The technical difference between pressed and moulded glass is that moulded glass-ware has taken its form from a mould under the pressure of a workman's breath, or of compressed air, whereas pressed glass-ware has taken its form from a mould under the pressure of a plunger.
Moulded glass receives the form of the mould on its interior as well as on its exterior surface.
For this reason every piece of pressed glass-ware, as soon as it is liberated from the mould, is exposed to a sharp heat in a small subsidiary furnace in order that the ruffled surface may be removed by melting.
Again, by raising the temperature, a metal in the solid state can be melted and liquefied, and poured into a mould to assume any form desired, which is retained when the metal cools and solidifies again; the gaseous state of a metal is revealed by the spectroscope.
As the molten metal is run in, the upward thrust on the outside mould, when the level has reached PP', is the weight of metal in the volume generated by the revolution of APQ; and this, by a theorem of Archimedes, has the same volume as the cone ORR', or rya, where y is the depth of metal, the horizontal sections being equal so long as y is less than the radius of the outside FIG.
The upward thrust is the same, however thin the metal may be in the interspace between the outer mould and the core inside; and this was formerly considered paradoxical.
Nowadays the mould-board is of steel with a chilled and polished surface to give greater wearing qualities and to reduce friction.
A frame is bolted to the beam and this carries the breast or mould-board to the fore-end of which the share is fitted.
During the greater part of the 19th century the ideal of ploughing was to preserve the furrow-slice unbroken, and this object was attained by the use of long mould-boards which turned the slices gently and gradually, laying them over against one another at an angle of 45°, thus providing drainage at the bottom of the furrow, and exposing the greatest possible surface to the influences of the weather.
Subsequently the digging plough came into vogue; the share being wider, a wider furrow is cut, while the slice is inverted by a short concave mould-board with a sharp turn which at the same time breaks up and pulverizes the soil after the fashion of a spade.
A third type is made on the "balance" principle, two plough beams with mould-boards being placed at right angles to one another, so that while the right-hand plough is at work the left-hand is elevated above the ground.
In the disk plough, which is built both as a riding and a walking plough, the essential feature is the substitution of a concavo convex disk, pivoted on the plough beam, for the mould-board and share of the ordinary plough.
In the United States and elsewhere engines drawing behind them a number of ploughs, arranged in echelon and taking perhaps The sub-soil plough has the beam and body but not the mould-board of an ordinary plough.
Stumps thirty or forty years old, at least, will still be sound at the core, though the sapwood has all become vegetable mould, as appears by the scales of the thick bark forming a ring level with the earth four or five inches distant from the heart.
The preference exhibited by yeast cells for sugar molecules is shared by mould fungi and soluble enzymes in their fermentative actions.
But the lessons thus learnt were sufficiently striking to mould his .whole character and policy.
Bound hand and foot he was thrown alive into a mould in which a block of concrete was about to be made.
Into the mould left by the saint's body liquid plaster of Paris was run, and a perfect model obtained, showing the features of the youth, the cords which bound him, and even the texture of his clothing.
High, with hills rising to 600 ft.; their sides are generally steep. The surface is covered with a rich mould unusual in coral islands, mixed towards the sea with sand, and having a substratum of red or blue clay.
Mould and bacterial growths, and causing the appearance, on the surface of their " mushroom garden," of numerous small white bodies formed by swollen ends of the fungus hyphae.
P. 99) "For sure our souls were near allied, and thine Cast in the same poetic mould with mine."
Next he sought to prepare the inactive form of the acid by artificial means; and after great and long-continued labour he succeeded, and was led to the commencement of his classical researches on fermentation, by the observation that when the inactive acid was placed in contact with a special form of mould (Penicillium glaucum) the right-handed acid alone was destroyed, the left-handed variety remained unchanged.
He was not cast in a heroic mould, and he had no desire to figure at the stake; like Cecil, and Elizabeth herself, he had a great respect for authority, and when his time came he could consistently impose authority on others.
In both there are species which form no nest or burrow, others which construct a simple silk-lined tunnel in the soil, and others which close the aperture of the burrow with a hinged door; while both share the habit of lining the burrow with silk to prevent the infall of loose sand or mould; and the species which make an open burrow close the aperture with a sheet of silk in the winter during hibernation and open it again in the spring.
In " Root rot," as the name implies, the roots are attacked, the fungus being a species of Ozonium, which envelops the roots in a white covering of mould or mycelium.
They may be divided into three classes: the pine lands, which often have a surface of dark vegetable mould, under which is a sandy loam resting on a substratum of clay, marl or limestone - areas of such soil are found throughout the state; the " hammocks," which have soil of similar ingredients and are interspersed with the pine lands - large areas of this soil occur in Levy, Alachua, Citrus, Hernando, Pasco, Gadsden, Leon, Madison, Jefferson and Jackson counties; and the alluvial swamp lands, chiefly in E.
The milk is then carefully dried by turning the mould round and round in the smoke produced by burning wood mixed with certain oily palm nuts; those of A ttalea excelsa are considered best, the smoke being confined within certain limits by the narrowness of the neck of the pot in which the nuts are heated.
The cakes when completed are, in order to remove them from the mould, slit open with a sharp knife, which is kept wet, and are hung up to dry.
Before it is put in, the article is roughly put together, and the expansion of the included air forces the rubber into contact with the internal surface of the mould, or a little carbonate of ammonia is enclosed.
A mass of glass in a viscous state can be rolled with an iron roller like dough; can be rendered hollow by the pressure of the human breath or by compressed air; can be forced by air pressure, or by a mechanically driven plunger, to take the shape and impression of a mould; and can be almost indefinitely extended as solid rod or as hollow tube.
When the glass is being blown in the mould the blowing iron is twisted round and round so that the finished bulb may not be marked by the joint of the mould.
Stem rot, due to a mould (Botrytis sp.), occurs in wet weather.
If zinc be cast into a mould at a red heat, the ingot produced is laminar and brittle; if cast at just the fusing-point, it is granular and sufficiently ductile to be rolled into sheet at the ordinary temperature.
It now remains my pleasant task to direct and mould the beautiful intelligence that is beginning to stir in the child-soul.
This thing, remaining essentially the same, receives in the same way other forms which constitute Plato and the other individuals of the species man; and, with the exception of those forms which mould that matter into the individual Socrates, there is nothing in Socrates that is not the same at the same time under the forms of Plato.
If the section of the finished tube is to be a triangle, with the enamel and bore at the base, the molten mass is pressed into a V-shaped mould before it is pulled out.
A sufficient weight of molten glass to form a bottle is gathered and placed in a funnel-shaped vessel which serves as a measure, and gives access to the mould which shapes the outside of the neck.
He therefore adapts himself to his circumstances, and, using the mould rather than the chisel, produces specimens which show tawdry handsomeness and are attractively cheap. It must be admitted, however, that even though foreign appreciative faculty were sufficiently educated, the Japanese artist in metals would still labor under the great difficulty of devising shapes to take the place of those which Europe and America have learned to consider classical.
I got out several cords of stumps in plowing, which supplied me with fuel for a long time, and left small circles of virgin mould, easily distinguishable through the summer by the greater luxuriance of the beans there.
Am I not partly leaves and vegetable mould myself?
Pythium, Peronospore, Completoria, Vol utelta, Botrytis, &c. That such overturgescence should lead to the bursting of fleshy fruits, such as gooseberries, tomatoes and grapes, is not surprising, nor can we wonder that fermentation and mould Fungi rapidly spread in such fruits; and the same is true for bulbs and herbaceous organs generally.
When you have kneaded it well, mould it, and bake it under a cover, that is, in a baking kettle.
When this is the case the gathering is carried to a block or half-open mould in which it is rolled and blown until it acquires, roughly, the shape of a hemisphere, the flat side being towards the pipe and the convexity away from it; the diameter of this hemisphere is so regulated as to be approximately that of the cylinder which is next to be formed of the viscous mass.
