The warmth from his body enveloped her mind in a thin casing of security.
The first act of the female after oviposition is to wrap her eggs in a casing of silk commonly called the cocoon.
Casing, having a collar to fit water-tight on the bevel shoulder, is inserted.
Four strings of iron casing are usually employed, having the following diameters: to in., 84 in., 64 in.
And 5 in., the lengths of tube forming the casing being screwed together.
The principle of this system consists essentially in the use of rotating hollow drilling rods or casing, to which is attached the drilling-bit and through which a continuous stream of water, under a pressure of 40 to loo lb.
The device employed for this purpose is known as the water-packer, and consists in its simplest form of an india-rubber ring, which is applied between the tubing and the well-casing, so that upon compression it makes a tight joint.
Casing descending freely, which obviously could not be accomplished with an ordinary bit introduced through the casing.
PYRAMIDION (diminutive of "pyramid"), an architectural term for the copper-gilt casing covering the apex of an obelisk, and generally extended to its upper termination of pyramidical form.
It is questionable whether it is not better, in cold soils and bleak situations, to abandon outdoor peach culture, and to cover the walls with a casing of glass, so that the trees may be under shelter during the uncongenial spring weather.
It is now ready either for incorporation with sulphur and other materials, or for agglomeration into solid masses by means of the masticating machine - an apparatus which consists of a strong cylindrical cast-iron casing, inside which there revolves a metal cylinder with a fluted or corrugated surface.
Some of the rubber having been placed in the annular space between the inner cylinder and the outer casing, the former is made to revolve; and the continued kneading action to which the rubber is subjected works it into a solid mass, something like a gigantic sausage.
The inner cylinder is generally placed somewhat excentrically in the outer casing, in order to render the kneading more perfect than would otherwise be the case.
The typical mine fan consists of a shaft upon which are mounted a number of vanes enclosed in a casing; the air entering a central side inlet is caught up by the revolving vanes and thrown out at the periphery by the centrifugal force thus generated.
" Openrunning " fans have no peripheral casing, and discharge freely throughout their entire circumference; in " closed " fans the revolving part is completely enveloped by a spiral casing opening at one point into a discharge chimney.
An outer cast-iron casing, which forms a steam jacket, and is fitted with a cylindrical curb or breast above the bottom.
The following is a brief description of the process and apparatus, as communicated by the courtesy of Messrs Henry Tate & Sons, Ltd.: Groups of cells or moulds are built within and against a cylindrical iron casing, by means of vertical plates inserted in grooves and set radially to the axis of the casing.
By means of a travelling crane the casing is placed within an iron drum, to which it is secured, and is then brought under an overhead vacuum pan, from which the cells are filled with massecuite.
After cooling, the casing is lifted out of the drum by a crane, assisted by compressed air, and is then conveyed by a travelling crane to a vertical centrifugal, inside of which it is made fast.
When this is done, the casing is hoisted out of the centrifugal and the vertical plates and the slabs of sugar are extracted.
Of these methods one of the chief is the plan of tubbing, or lining the excavation with an impermeable casing of wood or iron, generally the latter, built up in segments forming rings, which are piled upon each other throughout the whole depth of the water-bearing strata.
The lower quadrant of the casing is enlarged spirally, so as to leave a narrow rectangular opening at the bottom, through which the air is discharged into a chimney of gradually increasing section carried to a height of about 25 ft.
By the use of the spiral guide casing and the chimney the velocity of the effluent air is gradually FIG.
13, is an example of another class of centrifugal ventilator, in which a close casing is not used, the air exhausted being discharged from the circumference directly into the atmosphere.
This replaced the propeller of the ship whose engines were to be tested, and the outer casing was held from turning by a suitable arrangement of levers carried to weighing apparatus conveniently disposed on the wharf.
Sluices were arranged to slide be tween the wheel and casing, and by their means the range of action could be varied from 300 H.P. at 120 revs.
