I lifted the heavy wood beam that crossed their door, securing it.
He turned the beam around the yard and then shut the door.
He stepped through the doorway and turned the beam of light on her.
The beam was swallowed by the catacombs, and it was still too dark around her to see how large the underground world was.
Suddenly the beam caught a figure crouched ahead.
The beam of light extinguished and she felt around with trembling hands until she located the flashlight.
Turning the light back on, she pointed the beam on the area where the scream seemed to originate.
What is required is some means for localizing and directing a beam of radiation.
His Histoire de Beam was published at Paris in 1640.
The rood was carried either on a transverse beam, the " rood beam," or by a gallery, the " rood loft."
I replaced the beam securing the door on my side and without a word, left the cellar.
As they neared the first turn, something glinted in the beam of Dean's flashlight.
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.
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.
Asses are reared in Beam, Corsica, Upper Poitou, the Limousin, Berry and other central regions.
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.
Hence, if a be the width of the diffracted beam, and do the angle through which the wave-front is turned, ado = dX, or dispersion = /a ..
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.
Conceive a beam of plane polarized light to move among a number of particles, all small compared with any of the wavelengths.
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.
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.
See also Olhagaray, Histoire de Foix, Beam et Navarre (1609); Pierre de Marca, Histoire de Beam (1640).
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.
Y Y' is a so.- iron yoke, which rocks upon knife-edges K and constitutes the beam of the balance.
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.
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.
The samson-post, which supports the walking beam, and the jack-posts, are dove-tailed and keyed into the sills.
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.
Moreover, from the 12th century Beam enjoyed a kind of representative government, with tours plenieres composed of deputies from the three estates.
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.
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.
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.
The temper-screw forms the connecting link between the walking-beam and cable, and it is ' let out ' gradually to regulate the play of the jars as fast as the drill penetrates.
Faget de Baure, Essais historiques sur le Beam (1818); Les Fors de Beam, by Mazure and Hatoulet (1839), completed by J.
The cardboard scale SS is placed above a wooden screen, having in it a narrow vertical slit which permits a beam of light from the lamp L to reach the mirror of the magnetometer M, whence it is reflected upon the scale.
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.
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.
Brissaud and P. Roge in Textes additionnels aux anciens Fors de Bearn (1905); Leon Cadier, Les Etats de Beam depuis leur origine jusqu'au commencement du XVI e siecle (1888).
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.
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.
The first would correspond to a general turning of the beam; and the second would imply imperfect focusing of the central parts.
"Cat" or "cat-head," in nautical usage, is the projecting beam on the bows of a ship used to clear the anchor from the sides of the vessel when weighed.
- Beam; Gascogne (Basse-Navarre, Soule, Labord).
Teeth of radula beam-like, and at most three marginal teeth on each side.
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 engine, which is provided with reversing gear, is of 12 or 15 horse-power and motion is communicated through a belt to the band-wheel, which operates the walking-beam by means of a crank.
Hence a wide beam demands treatment with further apparatus (usually a telescope) of high magnifying power.
The screen might be separate from the rood beam or rood loft.
If a solution of the pigment is placed in the path of a beam of light which is then allowed to fall on a prism, the resulting spectrum will be found to be modified.
If x and y be co-ordinates in the plane of the wave-surface, the axis of y being parallel to the lines of the grating, and the origin corresponding to the centre of the beam, we may take as an approximate equation to the wave-surface -- -} z =+Bxy 2, +ax 3 13x2 2pp p y+-yxy2-?-Sy3+..
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.
