The surface of vessels may be spangled with gold or platinum by rolling the hot glass on metallic leaf, or iridescent, by the deposition of metallic tin, or by the corrosion caused by the chemical action of acid fumes.

In most modern works the greater part of these operations, as well as the actual rolling of the glass, is carried out by mechanical means, steam power and subsequently electrical power having been successfully applied to this purpose; the handling of the great weights of glass required for the largest sheets of plate-glass which are produced at the present time would, indeed, be impossible without the aid of machinery.

Since the surfaces produced by rolling have subsequently to be ground and polished, it is essential that the glass should leave the rolling-table with as smooth a surface as possible, so that great care is required in this part of the process.

The more elaborate patterns found on what is known as " figure rolled plate " are produced in a somewhat different manner; the glass used for this purpose is considerably whiter in colour and much softer than ordinary rolled plate, and instead of being rolled out on a table it is produced by rolling between two moving rollers from which the sheet issues.

The outer ends of the shore cantilevers are loaded to balance half the weight of the central girder, the rolling load, and 200 tons in addition.

This is due to the half weight of centre girder, the weight of the cantilever itself, the rolling load on half the bridge, and the wind pressure.

Rolling load taken at I.

The methods of erection may be classed as - (I) erection on staging or falsework; (2) floating to the site and raising; (3) rolling out from one abutment; (4) building out member by member, the completed part forming the stage from which additions are handled.

In such rolling operations the girder is subjected to straining actions different from those which it is intended to resist, and parts intended for tension may be in compression; hence it may need to be stiffened by timber during rolling.

But very great accuracy in drawing this curve is unnecessary, because the rolling stock of railways varies so much that the precise magnitude and distribution of the loads which will pass over a bridge cannot be known.

All that can be done is to assume a set of loads likely to produce somewhat severer straining than any probable actual rolling loads.

Reinach (Revue archeologique, 1904) finds the origin of the story in a picture, in which Sisyphus was represented rolling a huge stone up Acrocorinthus, symbolical of the labour and skill involved in the building of the Sisypheum.

When a distinction was made between the souls in the under world, Sisyphus was supposed to be rolling up the stone perpetually as a punishment for some offence committed on earth; and various reasons were invented to account for it.

The labour of rolling the metal by hand was done away with about 1760, by the firm of Tudor, Leader & Sherburn, who first employed horse-power, and for more than half a century the trade both in Sheffield and Birmingham continued to flourish.

When quite pure it is somewhat harder than tin, and its hardness is considerably increased by rolling.

The rapid advance in mechanical engineering in the latter part of this second period stimulated the iron industry greatly, giving it in 1728 Payn and Hanbury's rolling mill for rolling sheet iron, in 1760 John Smeaton's cylindrical cast-iron bellows in place of the wooden and leather ones previously used, in 1783 Cort's grooved rolls for rolling bars and rods of iron, and in 1838 James Nasmyth's steam hammer.

Hence steel which has been heated very highly, whether for welding, or for greatly softening it so that it can be rolled to the desired shape with but little expenditure of power, ought later to be refined, either by reheating it from below Are to slightly above Ac 3 or by rolling it after it has cooled to a relatively low temperature, i.e.

The shaping processes include the mechanical ones, such as rolling, forging and wire-drawing, and the remelting ones such as the crucible process of melting wrought iron or steel in crucibles and casting it in ingots for the manufacture of the best kinds of tool steel.

Of this power about half would be used at the blastfurnaces themselves, leaving 750,000 horsepower available for driving the machinery of the rolling mills, &c. This use of the gas engine is likely to have far - reaching results.

In order to utilize this power, the converting mill, in which the pig iron is converted into steel, and the rolling mills must adjoin t h e blast - furnace.

But, roll and re-roll as often as we like, much cinder remains imbedded in the iron, in the form of threads and rods drawn out in the direction of rolling, and of course weakening the metal in the transverse direction.

To bring them to a temperature suitable for rolling, these ingots must be set in heating or soaking furnaces (§ 125), and this should be done as soon as possible after they are cast, both to lessen the loss of their initial heat, and to make way for the next succeeding lot of ingots, a matter of great importance, because the charges of steel follow each other at such very brief intervals.

Yet the use of an open-hearth furnace of very great capacity, say of 200 tons per charge, has the disadvantage that such very large lots of steel, delivered at relatively long intervals, are less readily managed in the subsequent operations of soaking and rolling down to the final shape, than smaller lots delivered at shorter intervals.

But deepseated blowholes like those at B are relatively harmless in lowcarbon easily welding steel, because the subsequent operation of forging or rolling usually obliterates them by welding their sides firmly together.

The second is by casting it into a large rough block called an " ingot," and rolling or hammering this out into the desired shape.

Though the former certainly seems the simpler way, yet its technical difficulties are so great that it is in fact much the more expensive, and therefore it is in general used only in making objects of a shape hard to give by forging or rolling.

Heating Furnaces are used in iron manufacture chiefly for bringing masses of steel or wrought iron to a temperature proper for rolling or forging.

In order to economize power in these operations, the metal should in general be as soft and hence as hot as is consistent with its reachingalow temperature before the rolling or forging is finished, because, as explained in § 32, undisturbed cooling from a high temperature injures the metal.

Bringing such an ingot, then, to the rolling temperature is not really an operation of heating, because its average temperature is already above the rolling temperature, but one of equalizing the temperature, by allowing the internal excess of heat to " soak " through the mass.

To heat these on the intermittent plan for further rolling, i.e.

As the foremost end of the billet emerges from the furnace it enters the first of a series of roll-trains, and passes immediately thence to others, so that before half of the billet has emerged from the furnace its front end has already been reduced by rolling to its final shape, that of merchant-bars, which are relatively thin, round or square rods, in lengths of 300 ft.

The rolling mill in its simplest form is a pair of cylindrical rollers,.

The skin of the object, D, which is undergoing rolling, technically called " the piece," is drawn forward powerfully by the friction of the revolving.

For much the same reason rolling proceeds much faster than drawing, and on both these accounts it is incomparably the cheaper of the two.

Thus it comes about that rolling is so very much cheaper than either forging or drawing that these latter processes are used only when rolling is impracticable.

Great armour plates can indeed be made by rolling, because in making such flat plates the ingot is simply rolled back and forth between a pair of plain cylindrical rolls, like BB of fig.

Finally the quantity of armour plate needed is so enormous that it justifies the expense of installing a great rolling mill.

Pieces of very small cross section, like wire, are more conveniently made by drawing through a die than by rolling, essentially because a single draft reduces the cross section of a wire much more than a single pass between rolls can.

Pieces which vary materially in cross section from point to point in their length cannot well be made by rolling, because the cross section of the piece as it emerges from the rolls is necessarily that of the aperture between the rolls from which it is emerging, and this aperture is naturally of constant size because the rolls are cylindrical.

The fact that rolling is so much cheaper than forging has led engineers to design their pieces so that they can be made by rolling, i.e.

There are, in the town or its neighbourhood, great engineering, gun-making, and rolling and polishing works and breweries.

They are then spread out thinly on trays or racks made of bamboo, canvas or wire netting, under cover, for some 18 or 30 hours (according to the temporary weather conditions) to wither, after which they are in a soft, flaccid condition ready for rolling.

The object of rolling is to crush the leaves and to break their cells so as to liberate the juices.

Covering the higher parts of the south-western Palaeozoic area in most places are rolling hills of boulder clay or stony moraines; while the lower levels are plains gently sloping toward the nearest of the Great Lakes and sheeted with silt deposited in more ancient lakes when the St Lawrence outlet was blocked with ice at the end of the glacial period.

At the south-eastern end St Mary's river carries its waters to Lake Huron, with a fall of 602 to 581 ft., most of which takes place at Sault Sainte Marie, where the largest locks in the world permit vessels of 10,000 tons to pass from one lake to the other, and where water-power has been greatly developed for use in the rolling mills and wood pulp industry.

The flex nitive animal gods are not to be confused with the animal not ns ascribed to many cosmic deities; thus when the sun-god Osii was pictured as a scarabaeus, or dung-beetle, rolling its ball Isis lung behind it, this was certainly mere poetical imagery.

As a manufacturing centre Allegheny was outranked in 1905 by only two cities in the state - Philadelphia and Pittsburg; among the more important of its large variety of manufactures are the products of slaughtering and meat-packing establishments, iron and steel rolling mills, the products of foundries and machineshops, pickles, preserves and sauces, the products of railwayconstruction and repair shops, locomotives, structural iron and plumbers' supplies.

In the Theorie nouvelle de la rotation des corps (1834) he treats the motion of a 'rigid body geometrically, and shows that the most general motion of such a body can be represented at any instant by a rotation about an axis combined with a translation parallel to this axis, and that any motion of a body of which one point is fixed may be produced by the rolling of a cone fixed in the body on a cone fixed in space.

In 1901 the number of persons engaged in working of the raw material was 23,263, of whom 8258 were employed in steel smelting and founding, 7781 at blast furnaces in the manufacture of pig-iron, and 7224 at puddling furnaces and rolling mills.

Many of the patent bronzes are by slight variations in the proportions of the constituents made suitable for casting, for forging, and for rolling into sheets.

But in all the great modern manufacturing processes it is true that metals and alloys, though of the same name, have a different composition according as they are intended for casting on the one hand, or for forging, rolling and drawing on the other.

Steel intended for castings has slightly more carbon and other elements than the cast-steel ingot intended for rolling into plates.

On the west, in the dry region, this is occupied partly by the alluvial deposits of the Indus and its tributaries and the saline swamps of Cutch, partly by the rolling sands and rocky surface of the desert of Jaisalmer and Bikaner, and the more fertile tracts to the eastward watered by the Luni.

The new city (ciudad nueva and ciudad novisima) extends eastward over a beautiful tract of rolling country and is extending northward around the eastern shore of the bay.

The Caraballos Occidentales range is very complex; the central ridge is in some parts a rolling plateau, but it rises in Mt Data to 7364 ft., and numerous lofty spurs project from it.

El Reno lies on the rolling prairie lands, about 1360 ft.

In places the sands are fringed by long lines of Casuarina trees; in others, and more especially in the neighbourhood of some of the river mouths, there are deep banks of black mud covered with mangroves; in others the coast presents to the sea bold headlands, cliffs, mostly of a reddish hue, sparsely clad with greenery, or rolling hills covered by a growth of rank grass.

The industries which it has been the principal aim to foster and further develop are shipbuilding (naval and marine), steel foundries and rolling mills, sugar refineries, flour and oil mills, and distilleries.

The town is flourishing and rapidly increasing, and possesses very extensive wire factories (in connexion with which there are puddling and rolling works), machine works, and manufactories of gloves, baskets, leather, starch, chemicals, varnish, oil and beer.

The sloping surface is gently rolling, and has resulted from the uplift and dissection of a nearly level plain of erosion developed on folded, crystalline rocks.

A portion of this province in which weak rocks predominate gives an unusually broad valley region, known as the Valley of Virginia, drained by the Shenandoah river, and the headwaters of the James, Roanoke, New, and Holston rivers, which dissect the broad valley floor into gently rolling low hills.

This axis traces out a certain cone in the body, and a certain cone in space, and the continuous motion in question may be represented as consisting in a rolling of the former cone on the latter.

For the virtual work of two equal anc opposite forces will cancel in any displacement which is commor to the two surfaces; whilst, if one surface be fixed, the displace ment of that point of the rolling surface which was in contact with the other is of the second order.

The formula (13) may be easily verified in the case of the compound pendulum, or of the solid rolling down an incline.

Take, for example, the case of a sphere rolling on a plane; and let the axes Ox, Oy be drawn through the centre parallel to the plane, so that the equation of the latter is 1=cf.

Thus the centre of a sphere rolling under gravity on a plane of inclination a describes a parabola with an acceleration g sin a/(I+C/Ma)

Take next the case of a sphere rolling on a fixed spherical surface.

Let a be the radius of the rolling sphere, c that of the spherical surface which is the locus of its centre, and let x, y, I be the co-ordinates of this centre relative to axes through 0, the centre of the fixed sphere.

When the gravity of the rolling sphere is to be taken into account the preceding method is not in general convenient, unless the whole motion of G is small.

The slightest frictional forcessuch as the resistance of the aireven if they act in lines through the centre of the rolling sphere, and so do not directly affect its angular momentum, will cause the centre gradually to descend in an ever-widening spiral path.

Again, take the case of a circular disk rolling in steady motion on a horizontal plane.

By reasoning similar to that of 30, it appears that OT is the instantaneous axis of rotation 01 the rolling cone.

Now, as the line of contact OT is for the instant at rest on the rolling cone as well as on the fixed cone, the linear velocity of the point E fixed to the plane AOB relatively to the rolling cone is the same with its velocity relatively to the fixed cone.

The path of a point P in or attached to the rolling cone is a spherical epitrochoid traced on the surface of a sphere of the radius OP. From P draw PQ perpendicular to the instantaneous axis.

In the case of two shifting pieces this would involve equal and parallel velocities for all the points of each piece, so that there could be no rolling, and, in fact, the two pieces would move like one; hence, in the case of roIling contact, either one or both of the pieces must rotate.

That the angular velocities of a pair of turning pieces in rolling contact must be inversely as the perpendicular distances of any pair of points of contact from the respective axes.

That the linear velocity of a shifting piece in rolling contact with a turning piece is equal to the product of the angular velocity of the turning piece by the perpendicular distance from its axis to a pair of points of contact.

That for a pair of turning pieces with parallel axes, and for a turning piece and a shifting piece, the line of contact is straight, and parallel to the axes or axis; and hence that the rolling surfaces are either plane or cylindrical (the term cylindrical including all surfaces generated by the motion of a straight line parallel tO itself).

Turning pieces in rolling contact are called smooth or toothless wheels.

Shifting pieces in rolling contact with turning pieces may be called snfooth or toothless rae/es.

In a pair of pieces in rolling contact every straight line traversing the line of contact is a line of connection.

When the point of contact of two wheels lies between theim centres, they are said to be in outside gearing; when beyond theii centres, ip inside gearing, because the rolling surface of the larger wheel must in this case be turned inward or towards its centre.

If the velocity ratio is to be variable, as in s Williss Class B, the figures of the wheels are a pair of rolling curves, subject to the condition that the distance between their poles (which are the centres of rotation) shall be constant.

For full details as to rolling curves, see Williss work, already mentioned, and Clerk Maxwells paper on Rolling Curves, Trans.

To work with a wheel of any other figure, its section must be a rolling curve, subject to the condition that the perpendicular distance from the pole or centre of the wheel to a straight line parallel to the direction of the motion of the rack shall be constant.

The pitch-surfaces of a pair of toothed wheels are the ideal smooth surfaces which would have the same comparative motion by rolling contact that the actual wheels have by the sliding contact of their teeth.

The angular velocity ratio due to the sliding contact of the teeth will be the same with that due to the rolling contact of the pitch-circles, if the line of connection of the teeth cuts the Ca line of centres at the pitchpoint.

If the same rolling curve R, with the same tracing-point T, be rolled on the outside of any other pitch-circle, it will have the fare of a tooth suitable to work with the flank AT.

In like manner, if either the same or any other rolling curve be rolled the opposite way, on the outside of the pitch-circle BB, so that the tracing point T shall start from A, it will trace the face AT of a tooth suitable to work with a flank traced by rolling the same curve R with the same tracing-point T inside any other pitch-circle.

The figure of the path of con tact is that traced on a fixed plane by the tracing-point, when the rolling curve is rotated in such a manner as always to touch a fixed straight line EIE (or EIE, as the case may be) at a fixed point I (or I).

If the same rolling curve and tracing-point be used to trace both the faces and the flanks of the teeth of a number of wheels of different sizes but of the same pitch, all those wheels will work correctly together, and will form a set.

The teeth of a rack, of the same, set, are traced by rolling the rolling curve on both sides of a straight line.

The teeth of wheels of any figure, as well as of circular wheels, may be traced by rolling curves on their pitch-surfaces; and all teeth of the same pitch, traced by the same rolling curve with the same tracing-point, will work together correctly if their pitchsurfaces are in rolling contact.

Epicycloidal Teeth.The most convenient rolling curve is the circle.

Trundles and Pin-Wheels.If a wheel or trundle have cylindrical pins or staves for teeth, the faces of the teeth of a wheel suitable for driving it are described by first tracing external epicycloids, by rolling the pitch-circle of the pin-wheel or trundle on the pitch-circle of the driving-wheel, with the centre of a stave for a tracing-point, and then drawing curves parallel to, and within the epicycloids, at a distance from them equal to the radius of a stave.

The operations of describing the exact figures of the teeth of bevelwheels, whether by involutes or by rolling curves, are in every respect analogous to those for describing the figures of the teeth of spur-wheels, except that in the case of bevel-wheels all those operations are to be performed on the surface of a sphere described about the apex instead of on a plane, substituting poles for centres, and o B2

The first is by the method of instantaneous centres, already exemplified in 63, and rolling centroids, developed by Reuleaux in connection with his method of analysis.

Method 1.By reference to 30 it will be seen that the motion of a cylinder rolling on a fixed cylinder is one of rotation about an instantaneous axis T, and that the velocity both as regards direction and magnitude is the same as if the rolling piece B were for the instant turning about a fixed axis coincident with the instantaneous axis.

If B atops rolling, then the two cylinders continue to move as though they were parts of a rigid body.

These rolling cylinders are sometimes called axodes, and a section of an axode in a plane parallel to the plane of motion is called a centrode.

There is no restriction on the shape of these rolling axodes; they may have any shape consistent with i,olling (that is, no slipping is permitted), and the relative velocity of a point P is still found by considering it with regard to the instantaneous centre.

Reuleaux has shown that the relative motion of any pair of nonadjacent links of a kinematic chain is determined by the rolling together of two ideal cylindrical surfaces (cylindrical being used here in the general sense), each of which may be assumed to be formed by the extension of the material of the link to which it corresponds.

Rolling Resistance.By the rolling of two surfaces over each other without sliding a resistance is caused which is called sometimes rolling friction, but more correctly rolling resistance.

Its moment is found by multiplying the normal pressure between the rolling surfaces by an arm, whose length depends on the nature of the rolling surfaces, and the work lost in a unit of time in overcoming it is the product of its moment by the angular velocity of the rolling surfaces relatively to each other.

Among its industrial establishments are rolling mills, tube and pipe works, furnaces, steel mills, a brass foundry, and manufactories of electrical railway supplies, boxes, asbestos coverings, enamel work and ice.

Since at any instant the rolling curve is rotating about the point of contact with the axis, the line drawn from this point of contact to the tracing point must be normal to the direction of motion of the tracing point.

Also, since the axis is a tangent to the rolling curve, the ordinate PR is the perpendicular from the tracing point P on the tangent.

Hence the relation between the radius vector and the perpendicular on the tangent of the rolling curve must be identical with the relation between the normal PN and the ordinate PR of the traced curve.

In the annexed figure, there are shown various examples of the curves named above, when the radii of the rolling and fixed circles are in the ratio of I to 3.

It may be shown that if the distance of the carried point from the centre of the rolling circle be mb, the equation to the epitrochoid is x = (a+b) cos 0 - mb cos (a+b/b)0, y = (a +b) sin 9 - mb sin (a +b/b)0.

Leonhard Euler (Acta Petrop. 1784) showed that the same hypocycloid can be generated by circles having radii of; (a+b) rolling on a circle of radius a; and also that the hypocycloid formed when the radius of the rolling circle is greater than that of the fixed circle is the same as the epicycloid formed by the rolling of a circle whose radius is the difference of the original radii.

If the radius of the rolling circle be one-half of the fixed circle, the hypocycloid becomes a diameter of this circle; this may be confirmed from the equation to the hypocycloid.

The north and north-west portions of the lower peninsula - including the counties of Roscommon and Missaukee, parts of Wexford and Ogemaw, and those to the north and northwest of these - are occupied by a rolling plateau which attains an elevation at its highest point, north of its centre, of upwards of 1100 ft.

If the lead is therefore rightly proportioned to the standard of alloy, the resulting button will consist of only gold and silver, and these are separated by the operation of parting, which consists in boiling the alloy (after rolling it to a thin plate) in strong nitric acid, which dissolves the silver and leaves the gold as a coherent sponge.

In dry-country grasses the blades are often folded on the midrib, or rolled up. The rolling is effected by bands of large wedge-shaped cells - motor-cells - between the nerves, the loss of turgescence by which, as the air dries, causes the blade to curl towards the face on which they occur.

The rolling up acts as a protection from too great loss of water, the exposed surface being specially protected to this end by a strong cuticle, the majority or all of the stomata occurring on the protected surface.

Rhyn glanced from the rolling teal waves to his mate.  Her words about Gabe were troubling, and he couldn't determine if she was purposely vague or really didn't know.  Her pretty face was puzzled, and he frowned.  She was beyond tired.  Whatever was happening to her in the underworld, it wasn't good.  Anger filled him.  As much as he wanted to stay in the dream world in case it really was the last time he saw her, he couldn't help her while stuck in the dream.

He appeared as if he'd been rolling in blood; he was soaked through with it, his eyes glowing with the wildness of bloodlust.
