The bearings were FIG.

All three flags were of such a size as to be conveniently attached to and carried on a lance, and were emblazoned with the arms or some portion of the bearings of their owners.

Somewhat later the adoption of hereditary surnames and armorial bearings marked the existence of a large and noble class who either from the subdivision of fiefs or from the effects of the custom of primogeniture were very insufficiently provided for.

Here, as elsewhere in the old time, a nobleman and a gentleman meant the same thing, namely, a man who under certain conditions of descent was entitled to armorial bearings.

When it is desired to read a line in the reverse direction the telescope is lifted out of the cradle, turned end for end, and replaced in the Y bearings of the cradle again.

But in both works these utterances are qualified in such a manner as to enable us to perceive the real bearings of his doctrine, and to pronounce at once that it differs widely from that commonly ascribed to him.

It is also used for bearings in watches and electric meters.

It is utilized in the spindles of machinetools, in the balls and rollers for high-speed bearings, slides, pivots and such like.

The declination axis rests on bearings attached to opposite sides of the polar axis.

An oblong metallic box fitted with pivots, whose bearings are attached to the triangular beams, forms the tube for two parallel telescopes; these are separated throughout their length by a metallic diaphragm.

The wheel W is therefore mounted on a guided rod, which is forced upwards by suitable levers and weights, and this relief of pressure is precisely proportional to the pressure on the respective bearings.

The declination axis is here represented by what are practically the trunnions or pivots of the tube, resting in bearings which are supported by the arms of a very massive cast-iron fork bolted to the upper end of the polar axis.

This axis is a hollow forging of nickel steel, of which the accurately turned pivots rest on bearings attached to cast-iron uprights bolted upon a massive cast-iron base plate.

This float dips into a tank filled with mercury so that practically the entire instrument is floated by the mercury, leaving only sufficient pressure on the bearings to ensure that the pivots will remain in contact with them.

The sleeve carries a crosspiece on its upper extremity to which the bearings of the horizontal axis c are attached.

This is also the case as to geology, and the bearings of geological evidence on the probable nature and extent of the Antarctic continent, and the relations of that land mass to the other continents.

These Losses Were As Far As Possible Eliminated By Combining The Trials In Pairs, With Differ Ent Loads On The Brake, Assuming That The Heat Loss Would Be The Same In The Heavy And Light Trials, Provided That The External Temperature And The Gradient In The Shaft, As Estimated From The Temperature Of The Bearings, Were The Same.

The remaining equations serve to determine the reactions of the rotating body on its bearings.

If we reverse the signs, we get the centrifugal couple exerted by the solid on its bearings.

In mechanism it is usually the central line either of a rotating shaft or axle having journals, gudgeons, or pivots turning in fixed bearings, or of a fixed spindle or dead centre round which a rotating bush turns; but it may sometimes be entirely beyond the limits of the turning body.

The pair of shafts Ci, C2 terminate in a pair Ci of forks F,, F2 in bearings at the extremities of which turn the gudgeons at the ends of the 0o arms of a rectangular cross, F3 having its centre at 0.

This cross is the link; the connected points are the centres of the F bearings F1, F2.

If a force be applied to a turning piece in a line pot passing through its axis, the axis will press against its bearings with an equal and parallel force, and the equal and opposite reaction of the bearings will constitute, together with the first-mentioned force, a couple whose arm is the perpendicular distance from the axis to the line of action of the first force.

Balanced Lateral Pressure of Guides and Bearings.The most important part of the lateral pressure on a piece of mechanism is the reaction of its guides, if it is a sliding piece, or of the bearings of its axis, if it is a turning piece; and the balanced portion of this reaction is equal and opposite to the resultant of all the other forces applied to the piece, its own weight included.

For further information on this point and on Osborne Reynoldss theory of lubrication see BEARINGS and LUBRICATION.

The heat produced by friction, when moderate in amount, is useful in softening and liquefying thick unguents; but when excessive it is prejudicial, by decomposing the unguents, and sometimes even by softening the metal of the bearings, and raising their temperature so high as to set fire to neighboring combustible matters.

For modern methods of forced lubrication see BEARINGS.

Hence, unless there be some reason to the contrary, each piece of a machine should be balanced on its axis of rotation; otherwise the centrifugal force will cause strains, vibration and increased friction, and a tendency of the shafts to jump out of their bearings.

It is essential to the steady motion of every rapidly rotating piece in a machine that its axis of rotation should not merely traverse its centre of gravity, but should be a permanent axis; for otherwise the centrifugal couples will increass friction, produce oscillation of the shaft and tend to make it leave its bearings.

To take a simple case, suppose a shaft supported on two bearings to carry a disk of weight W at its centre, I and let the centre of gravity of the disk be at a distance e from the axis of rotation, this small distance being due to imperfections of material or faulty construction.

Births.-Apart from the information which the statistics of birth furnish as to the growth of population, they have, like those of marriage, and perhaps to even a greater extent, a special social interest from their bearings upon the moral conditions of the community to which they relate.

The Riddarhus (house of the nobility) was the meeting-place of the Council of the Nobles until 1866, and its hall is adorned with the armorial bearings of noble families.

By this time the colonists of British descent predominated in the eastern provinces - a circumstance which had important bearings on the future of the colony.

In many cases the colour-production is dependent on certain definite conditions - temperature, presence of oxygen, nature of the food-medium, &c. Ewart's important discovery that some of these lipochrome pigments occlude oxygen, while others do not, may have bearings on the facultative anaerobism of these organisms.

Thus the mitre over an English bishop's coat-of-arms is a survival which indicates him as the successor of bishops who actually wore mitres, while armorial bearings themselves, and the whole craft of heraldry, are survivals bearing record of a state of warfare and social order whence our present state was by vast modification evolved.

When constructed for purposes of extreme accuracy they will turn with the one-millionth part of the load weighed, though to ensure such a result the knife-edges and their bearings must be extremely hard (either hardened steel or agate) and worked up with great care.

To keep the beam truly in its place, which is very necessary, as all the bearings are flat,the re From Airy, " On Weighing Machines," Institution of Civil Engineers, 1892.

The upper end of this rod is formed into a loop, and this loop pulls upon a knife-edge which is fixed to a short lateral arm rigidly attached to a vertical disk, and this disk turns in bearings formed in the frame of the machine.

This disk rotates by rocking on a pair of knife-edges whose bearings are rigidly attached to the frame.

The trucks or other receptacles containing the coal, &c., are drawn upon the platform of the machine, and the pull of the load is transferred by a vertical rod at the left-hand end of the machine to the knife-edge on the short arm of the steelyard, whose fulcrum is carried on bearings in the frame.

This can be accomplished by attaching balance-weights to the pulley until it will remain stationary in all positions, when its shaft rests on two horizontal knife-edges in the same horizontal plane, or, preferably, the pulley and shaft may be supported on bearings resting on springs, and balanced by attached masses until there is no perceptible vibration of the springs at the highest speed of rotation.

Alloys prepared in this way, and known as phosphor bronze, may contain only about 1% of phosphorus in the ingot, reduced to a mere trace after casting, but their value is nevertheless enhanced for purposes in which a hard strong metal is required, as for pump plungers, valves, the bushes of bearings, &c. Bronze again is improved by the presence of manganese in small quantity, and various grades of manganese bronze, in some of which there is little or no tin but a considerable percentage of zinc, are extensively used in mechanical engineering.

Suppose B not to be fixed, but to be capable of moving against some third body C (which might, e.g., contain cylindrical bearings, if B were a drum with its shaft), itself fixed, - and further, suppose the frictional resistance between B and C to be the only resistance to B's motion.

His investigations must embrace not only the comparative morphology and anatomy of fossil plants, but also their distribution over the earth's surface at different periods - a part of the subject which, besides its direct biological interest, has obvious bearings on ancient climatology and geography.

Nevertheless the full bearings of the philosophic question were somewhat obscured by the comparatively limited fashion in which it was then regarded.

Can a new meaning to accounting be discovered; one that helps gives new bearings in an increasingly amoral world?

In an age enamored of machines, life becomes amoral, without moral bearings, devoid of moral categories.

Blind Cricket is played with a size three football containing ball bearings.
