It is struck by a wooden beam swung on the outside, and only at the changes of the night-watches, when its deep tone may be heard in all parts of the city.
In the autumn of 1786 there was an encounter near the village of East Lee between about 250 adherents of Daniel Shays (many of them from Lee township) and a body of state troops under General John Paterson, wherein the Shays contingent paraded a bogus cannon (made of a yarn beam) with such effect that the state troops fled.
Deflections of the suspended needle are indicated by the movement of a narrow beam of light which the mirror reflects from a lamp and focusses upon a graduated cardboard scale placed at a distance of a few feet; the angular deflection of the beam of light is, of course, twice that of the needle.
If 1 2 and 1 1 be the thicknesses traversed by the extreme rays, and a denote the width of the emergent beam, the dispersion is given by 0 Sµ 0 2 - 11)/a, or, if t i be negligible, 0 = Sµt/a (6) The condition of resolution of a double line whose components subtend an angle 0 is that 0 must exceed X/a.
The play of the beam is limited by a stop S and a screw R, the latter being so adjusted that when the end Y of the beam is held down the two air-gaps are of equal width.
In either case (as also with a prism) the position of minimum deviation leaves the width of the beam unaltered, i.e.
I love to weigh, to settle, to gravitate toward that which most strongly and rightfully attracts me--not hang by the beam of the scale and try to weigh less--not suppose a case, but take the case that is; to travel the only path I can, and that on which no power can resist me.
We may now investigate the mathematical expression for the disturbance propagated in any direction from a small particle upon which a beam of light strikes.
12039 of 1896) brought forward the idea of focusing a beam of electric radiation for telegraphic purposes on a distant station by means of parabolic mirrors, and tried this method successfully on Salisbury Plain up to a distance of about a couple of miles.
The samson-post, which supports the walking beam, and the jack-posts, are dove-tailed and keyed into the sills.
Moreover, from the 12th century Beam enjoyed a kind of representative government, with tours plenieres composed of deputies from the three estates.
Although, when Beam was annexed to the domains of the crown, it was granted a conseil d'etat and a parlement, which sat at Pau, the province also retained its fors until the Revolution.

If the cardboard scale upon which the beam of light is reflected by the magnetometer mirror is a flat one, the deflections as indicated by the movement of the spot of light are related to the actual deflections of the needle in the ratio of tan 20 to 0.
The aperture of the unretarded beam may thus be taken to be limited by x = - h, x = o, y= - 1, y= +1; and that of the beam retarded by R to be given by x =o, x =h, y = - 1, y = +l.
The engine works a massive counter-balanced walking-beam from which is suspended in the shaft a long wooden (or steel) rod, made in sections and spliced together.
It is said that Eleazar, the priest who guarded the treasure, offered Crassus the golden beam as ransom for the whole, knowing, what no one else knew, that it was mainly composed of wood.
During the siege of La Rochelle he performed a mission which brought him in touch with Richelieu, who shortly afterwards nominated him intendant de justice in Beam (1631), and in 1639 summoned him to Paris with the title of counsellor of state.
Faget de Baure, Essais historiques sur le Beam (1818); Les Fors de Beam, by Mazure and Hatoulet (1839), completed by J.
Y Y' is a so.- iron yoke, which rocks upon knife-edges K and constitutes the beam of the balance.
Later investigations by Fraunhofer, Airy and others have greatly widened the field, and under the head of " diffraction " are now usually treated all the effects dependent upon the limitation of a beam of light, as well as those which arise from irregularities of any kind at surfaces through which it is transmitted, or at which it is reflected.
The screen might be separate from the rood beam or rood loft.
The great governments were: Alsace, Saintonge and Angoumois, Anjou, Artois, Aunis, Auvergne, Beam and Navarre, Berry, Bourbonnais, Bourgogne (Burgundy), Bretagne (Brittany),, Champagne, DauphinC, Flandre, Foix, Franche-Comt, Guienne and Gascogne (Gascony), Ile-de-France, Languedoc, Limousin, Lorraine, Lyonnais.
An ebonite beam B is rocked up and down rapidly by a train of mechanism, and moves the cranks FIG.
The first part will be, as before, zinc to the line; at the next half stroke of the beam M will not pass through, as there is no hole in the paper; but at the third half stroke it passes through and copper is put to the line.
This coloring matter, as shown by its absorption spectrum, picks out of the ordinary beam of light a large proportion of its red and blue rays, together with some of the green and yellow.
Leaves respond in another way to the same influence, placing themselves across the path of the beam of light.
The samson-post is placed flush with one side of the main sill, the band-wheel jack-post being flush with the other side, so that the walking-beam, which imparts motion to the string of tools, works parallel with the main sill.
The headache-post is a vertical wooden beam placed on the main sill directly below the walking-beam, to receive the weight of the latter in case of breakage of connexions.
If now the vertical movement of the walking-beam be 24 in., when 'it starts on the up-stroke the sinker-bar rises 4 in., and the cross-heads come together with a smart blow, then the auger-stem is picked up and lifted 20 in.
