Probably you refer to disking, and for that an ordinary disk is used with the disks set pretty straight to reduce the side cutting, and this is done at different times of the year by different growers.
Plow them under early in the spring and close the covering and compact the green stuff by running a straight disk over the ground after plowing.
If, then, the bolt disk being at the back, there are three letter disks and the spindle is rotated to the left, the bolt disk will in the course of one revolution pick up letter disk No.
Each disk, including the bolt disk, is provided with a pin projecting from its surface in such a way that the pin of one disk comes into contact with that of the next disk and drives it round.
Seps, of the Mediterranean countries and south-western Asia, has a transparent disk on the lower eyelid which is movable; limbs very short or reduced to mere vestiges.

Again, take the case of a circulardisk rolling in steady motion on a horizontal plane.
The centre O of the disk is supposed to describe a horizontal circle of radius c with the constant angular velocity [.

In adult Holocephali and in Polyodon and Torpedo there is no exoskeleton, in young Holocephali, however, there are a few small dorsal ossifications.
In Megalobatrachus two or even three centralia sometimes occur.
Skeletal structures of epiblastic and hypoblastic origin occur in the Urochordata.
This, like the carpus, is much reduced and modified from the primitive condition.
The Theropoda vary greatly in size, one of the best known genera Compsognathus was about as large as a cat, another, Megalosaurus, perhaps as large as an elephant.
In larval Tunicata and in adults of the group Larvacea the tail is supported by a typical notochord, which is confined to the tail.
The premaxillae are united, and in front of them is a pointed beak-like bone which bites upon a toothless predentary ossification of the mandible.
The last-named writer divides the genus into three subgenera.
There are two principal types of Teleostean scales, the cycloid and ctenoid.
All these rods are united at intervals by transverse rods.
The anterior limbs are but little shorter than the posterior ones.
The suborder Orthopoda may be further subdivided into three sections:-- A.
We also find in the hen's egg, when we break the shell and take out the yelk, a round small white disk at its surface which corresponds to the tread.
At the beginning of germination the flat embryonic disk curves outwards, and separates on the inner side from the underlying large yelk-ball.
Germinal area or germinal disk of the rabbit, with sole-shaped embryonic shield, magnified about ten times.
B In the middle of the germinal disk we find the medullary groove (mr), and underneath it the chorda (ch).
The germinative area or gastric disk of the animal consists at first (like the germinal disk of birds and reptiles) merely of the two primary germinal layers, the ectoderm and entoderm.
Between the lens-shaped disk of the morula-cells and the underlying white yelk a small cavity is now formed by the accumulation of fluid, as in the fishes.
The germinal diskof the hen's ovum at the beginning of gastrulation; A before incubation, B in the first hour of incubation.
If we make a vertical section through this part, we see that a flat and broad cleft stretches under the germinal disk forwards from the primitive mouth; this is the primitive gut (Figure 1.
Longitudinal section of the germinal disk of a siskin (discogastrula).
I stood, in fact, just under the door; but I could see on the wall facing me, at the point where the stairs turned a bright disk of light suddenly appear, such as a lamp will throw.
He had become silent while the others talked, and he half reclined against a tree, looking at the sky that showed a dim and shadowy disk through the opening.
His gaze shifted from the red coals to the silver disk of the sky.
Henry lifted the other foot, caught his toe on the edge of the disk and stumbled headlong into the column of light.
From both floor disk and upper disk leaped strange cones of blue light, which met midway to form an hour-glass shape of brilliance.
The blue light, hissing, drove from diskto disk; the room thundered with the roar of the machine, before which stood Dr.
Above these, again, come the royal ovals, surmounted by the solar disk between two uræus serpents.
In the latter the disk which represents the sun is red, and stands boldly out from the green of the two wings.
The compartments of ceiling decorations have scarabs in their centres, and upon the mummy cases it is occasionally substituted for the uræus-crowned disk in the centre of a huge pair of extended wings.
One face of this disk was generously perforated, the other, solid, boasted a short blunt post round which several feet of extremely fine wire had been coiled.
The water intervening between the whitedisk and the observer did not present the brilliant and vivid green tint which characterized that which is seen in the shallow portions of the Lake, where the bottom is white.
It's the energy of the spinning disk that is changed into heat.
Now, if you spin a copper disk in a magnetic field, you get eddy currents.
Then, if you're obstinate about it, you get the equivalent of the copper disk melting.
Just as the red disk of the sun sunk down behind this stupendous scenery, a low, guttural sound was uttered by Potlatch Hero, an old Indian brave, and it passed along the line of the shadowy braves.

Round the upper part of the disk is a metal band, A, to which the circuit wire is attached, and the current thus passed on to the next lamps.
No nice and troublesome adjustment with reference to the length of the electric arc is requisite, and simple contact between the point of the rod and the surface of the disk is sufficient for the manifestation of the light.
