A sharp action began, but Mercy hearing the drums and fifes of the French infantry in the Glotter Tal broke it off and continued his retreat in good order.
Moreover, just as Pierre was speaking a sharp rattle of drums was suddenly heard from both sides.
Of these there are two main systems: (1) a continuous cable is carried over two main drums at each end of the line, and the motion is derived either (a) from the weight of the descending load or (b) from a motor acting on one of the main drums; (2) each end of the cable is attached to wagons, one set of which accordingly ascends as the other descends.
The weight required to cause the downward motion is obtained either by means of the material which has to be transported to the bottom of the hill or by water ballast, while to aid and regulate the motion generally steam or electric motors are arranged to act on the main drums, round which the cable is passed with a sufficient number of turns to prevent slipping.
The drums were beating, the fifes were playing.
In a type built with vertical sections each division is complete in itself, and is not directly connected with the next section, but communicates with flow and return drums. A defective section may thus be left in position and stopped off by means of plugs from the drums until it is convenient to fit a new one in its place.
Accounts differ as to his conduct at the execution, some stating that he ordered a roll of drums to drown the king's voice.
The family tradition, however, is that he silenced the drums to enable Louis to speak to the people, and that General J.
Berruyer, who was in sole command, ordered the drums to beat and thus drowned the last words of the king's speech.
All of them lie in a state of ruin, and, from the disposition of the drums of the columns, it is impossible to suppose that their fall was due to any other cause than an earthquake.
In one courtyard of this temple are deposited the celebrated ten stone drums which bear poetical inscriptions commemorative of the hunting expeditions of King Suan (827-781 B.C.), in whose reign they are believed, though erroneously, to have been cut; and in another stands a series of stone tablets on which are inscribed the names of all those who have obtained the highest literary degree of Tsin-shi for the last five centuries.
In 1875, at Taunton, special prizes were awarded for onehorse and two-horse mowing-machines, hay-making machines, horse-rakes (self-acting and not self-acting), guards to the drums of threshing-machines, and combined guards and feeders to the drums of threshing-machines.
Drums beat the charge, Murat led the way through the corridors of the palace to the Orangerie, and levelled bayonets ended the existence of the Council.
The peristyle, if we compare the measurements of the stylobate with those of the drums built into the wall of the Acropolis, may be concluded to have consisted of six Doric columns at the ends and twelve at the sides.
Hence processes have been patented in which the objects to be plated are suspended in revolving drums between the anodes, the rotation of the drum causing the constant renewal of surfaces and affording a burnishing action at the same time.
In the tail-rope system of haulage, best adapted for single track roads, there are two ropes - a main and a " tail " rope - winding on a pair of drums operated by an engine.
- Plan of direct-acting hoisting engines, compound Corliss engines and conical drums. Wellman-Seaver-Morgan Co., Cleveland, Ohio, makers.
The engine is direct-acting, the drums making one revolution for each double stroke.
In geared hoists the drums. are on a separate shaft, driven from the crank-shaft by tooth or friction gearing, and make one revolution for, say, 4 or 5 double strokes.
Drums are either cylindrical or conical.
If, for a twocompartment shaft, a pair of drums (or a single wide drum) be keyed to the engine shaft, with the ropes wound in opposite directions, the hoisting is " in balance," that is, the cages and cars counterbalance each other, so that the engine has to raise only the useful load of mineral, plus the rope.
Independent drums, on the contrary, are loose upon their shaft, and are thrown on or off by tooth or friction clutches.
The maximum load on the engine is thus greater and more power is required than for fixed drums. Steam consumption is economized, whenever possible, by throwing in the clutches of both drums and hoisting in balance.
Fixed drums are best for mines in which the hoisting is done chiefly from one level; independent drums when there are a number of different levels.
Sometimes, especially at early dawn, there is a musical noise in the desert, like the sound of distant drums, which is caused by the eddying of grains of sand in the heated atmosphere, on the crests of the medanos.
With drums beating and colours flying, every unit within call went forward for the final effort.
On the tail rope plan the engine has two drums worked by spur gearing, which can be connected with, or cast loose from, the driving shaft at pleasure.
The same thing can be effected in a more perfect manner by the use of spiral or scroll drums, in which the rope is made to coil in a spiral groove upon the surface of the drum, which is formed by the frusta of two obtuse cones placed with their smaller diameters outwards.
The great size and weight of such drums are also disadvantages, as giving rather unmanageable dimensions in a very deep pit.
In breaking up and sending out the carbide for commercial work, packed in air-tight drums, the crust is removed by a sand blast.
For instance, in practical working it has been found that a furnace return of oï¿½ 504 lb per kilowatt hour is brought down to 0.406 lb per kilowatt hour when the material has been broken up, sorted and packed in air-tight drums. In the tapping process a fixed crucible is used, lined with carbon, the electrode is nearly as big as the crucible and a much higher current density is used.
He discovered and sent to England parts of several sculptured drums (columnae caelatae) of the latest temple, and archaic sculptures from the drums and parapet of the earlier building.
Fragments of reliefsculptures belonging to the parapet and columns, and of fluted drums and capitals, cornices and other architectural members have been recovered, showing that the workmanship and Ionic style were of the highest excellence, and that the building presented a variety of ornament, rare among Hellenic temples.
Judged by the diameter of the drums, the columns of the Croesus temple were not two-thirds of the height of those of the Hellenistic temple.
This is performed by carrying them over a series of smaller cylinders or drums by means of tapes.
In the older type of machine it 'is next led up to the right- ' hand one of the two reversing drums, which are placed above the large printing cylinders, and over which it passes with the printed side downwards.
The inking arrangements are placed at the two extreme ends of these four drums or cylinders, thus being near the type surfaces in each case.
Cords require either cylindrical drums with ledges or grooved pulleys.
Chains require pulleys or drums, grooved, notched and toothed, so as to fit the links of the chain.
Wrapping connectors for communicating reciprocating motion have usually their ends made fast to the pulleys or drums which they connect, and which in this case may be sectors.
Pulleys and drums for communi cating a constant velocity ratio are circular.
The angular velocities of a pair of connected circular pulleys or drums are inversely as the effective radii.
