The result is that no trace of " fiddling " exists, and the movable and fixed webs come sharply together in focus with the highest powers.
In the middle of this slide a stiffly fitting brass disk is inserted, to which a small turn-table motion may be communicated by an attached arm, acted on by two fine opposing screws accessible to the astronomer; and by their means the " fixed web " may be rendered strictly parallel with the movable one.
Next the star B is bisected by the fixed web and A by the movable one.
9) is only prevented by good fitting of the holes 1 3' y'; and, since the weight of the slide is on one side of the screw, misfit here will have the effect of changing the reading for coincidence of the movable with the fixed web in reverse positions of the micrometer.
These furrows have apparently been cut in situ with a very accurate engine; for not the slightest departure from parallelism can be detected in any of the movable webs relative to the fixed webs.
Extraordinary care has evidently been bestowed in adjusting the parallelism and distance of the planes and A, so that the movable wires shall almost, but not quite, touch the surface T.
The end-plane of this cylinder receives the pressure of the micrometer screw, so that by turning the small drum-head the coincidence-reading of the movable web with the fixed web can be changed, and thus any given angle can be measured with different FIG.
If the reading for coincidence of the movable with the fixed webs is known, we then obtain from the single reading of S the difference from coincidence of the divisions of the two scales.
The webs of each set of movable webs shall, inter se, be strictly parallel, and the two sets shall be strictly at right angles to each other.
The micrometer readings for coincidence of the movable webs with the webs of the fixed square shall be exactly 0 000R and io-000R.
His proposal to impose a tax of 1% on real property and of 2% on movable property was rejected by all the larger provinces.
This liability is overcome by making such movable parts as require to be magnetic of soft iron, and magnetizing them by the inducing action of a strong permanent magnet.
From the general confiscation were exempted the buildings actually used for public worship, as episcopal residences or seminaries, &c., or which had been appropriated to the use of schools, poorhouses, hospitals, &c.; as well as the buildings, appurtenances, and movable property of the abbeys of Monte Casino, Della Cava dci Tirreni, San Martino della Scala, Monneale, Certosa near Pavia, and other establishments of the same kind of importance as architectural or historical monuments.
The last I to 5 of these vertebrae have movable ribs which do not reach the sternum, and are called cervico-dorsals.
There is no other protection, but slight, imperfectly movable folds of skin arise from the outer rim.
Originally small and movable, it was afterwards made of large proportions and fixed in one place.
Judaean tradition dated the sanctity of Jerusalem from the installation of the ark, a sacred movable object which symbolized the presence of Yahweh.
Churches at Rome the paschal candlesticks were fixtures, but elsewhere they were usually movable, and were brought into the church and set up on the Thursday before Easter.
At one end of the band-wheel shaft is the bull-rope pulley, and upon the other end is a crank having six holes to receive a movable wrist-pin, the length of stroke of the walking-beam being thus adjusted.
- Shunted Movable Coil Ammeter, Isenthal & Co.
In this last case the shunt need not be contained in the instrument itself but may be at a considerable distance, wires being brought from the shunt which carries the main current to the movable coil ammeter itself, which performs the function simply of an indicator, 3.
If then the torsion head is provided with an index needle, and also if the movable coil is provided with an indicating point, it is possible to measure the torsional angle through which the head must be twisted to bring the movable coil back to its zero position.
Above and below these movable coils, which form as it were the two scalepans of a balance, are fixed other stationary coils, and the connexions of all these six coils (shown in fig.
This tendency is resisted by the weight of a mass of metal, which can be caused to slide along a tray attached to the movable coils.
4 Movable types are utilized in several other ways in the production of maps.
Thus prepared, the specimens are placed on shelves or movable trays, at intervals of about 6 in., in an air-tight cupboard, on the inner side of the door of which, as a special protection against insects, is suspended a muslin bag containing a piece of camphor.
Finally, the council pronounced in favour of the pope's renunciation of the right to the movable property of deceased prelates (spolium) as well as of the right of procurations.
There is ample equipment of fixed and movable staiths and cranes of various sizes up to 70 tons, the Lewis-Hunter patent cranes being largely used for shipping coal owing to their minimizing the breakage of coal and securing its even distribution.
On the other hand, it may well be doubted whether the pygidial or posterior carapace is primarily due to a fusion of the tergites of somites which were previously movable and well developed.
With this machine movable type shuttles can be used, and one can have several shuttles, each with a different set of characters--Greek, French, or mathematical, according to the kind of writing one wishes to do on the typewriter.
Stc, The sterno-coxal process or a, b, c, d, Movable processes on the jaw-like up-growth of the coxa.
Many of those that are movable have been transferred to Madrid, and many others have perished by fire or sack.
-> CH3C6H5CONHC6H51 N OH Syn-phenyltolylketoxime CH3 C6H4 C C6H5 CH3C6H4NH000,H5 HO N A nti-tolylphenylketoxime In the case of the aldoximes, that one which most readily loses the elements of water on dehydration is assumed to contain its hydroxyl radical adjacent to the movable hydrogen atom and is designated the syn-compound.
In it Maclaurin developed several theorems due to Newton, and introduced the method of generating conics which bears his name, and showed that many curves of the third and fourth degrees can be described by the intersection of two movable angles.
Such an instrument is called a shunted movable coil ammeter, and is represented by a type of instrument shown in fig.
In this magnetic field is pivoted a small circular or rectangular coil carried in jewelled bearings, the current being passed into and out of the movable coil by fine flexible conductors.
In the case of ammeters intended for very small currents, the whole current can be sent through the coil, but for larger currents it is necessary to provide in the instrument a shunt which carries the main current, the movable coil being connected to the ends of this shunt so that it takes a definite small fraction of the current passed through the instrument.
Direct reading equidivisional movable coil ammeters can be made in various portable forms, and are very much employed as laboratory instruments and also as ammeters for the measurement of large electric currents in electric generating stations.
F, Fixed coil; D, Movable coil; S, Spiral spring; T, Torsion head; MM, Mercury cups; I, Index needle.
The current can be passed into and out of the movable coil by permitting the ends of the coil to dip into two mercury cups.
If a current is passed through the fixed coil and movable coil in series with one another, the movable coil tends to displace itself so as to bring the axes of the coils, which are normally at right angles, more into the same direction.
