In depths beyond the reach of wave motion, and apart from suspension across a submarine gully, which will sooner or later result in a rupture of the cable, the most frequent cause of interruption is seismic or other shifting of the ocean bed, while in shallower waters and near the shore the dragging of anchors or 40 fishing trawls has been mostly responsible.
Since by international agreement the wilful damage of a cable has been constituted a criminal offence, and the cable companies have avoided crossing the fishing banks, or have adopted the wise policy of refunding the value of anchors lost on their cables, the number of such fractures has greatly diminished.
Petroleum refineries, iron-foundries, chemicals, soap-boiling, silk-spinning and the production of ships' fittings, as marine steam boilers, anchors, chains, cables, are the other principal branches of industry.
In navigation he suggested many new contrivances, such as water-tight compartments, floating anchors to lay a ship to in a storm, and dishes that would not upset during a gale; and beginning in 1757 made repeated experiments with oil on stormy waters.
The anchors are built up of steel plates and angle bars, and are buried in a large mass of concrete.
The profits of the trade were enormous; it was said that even the anchors of ships returning from Spain were made of silver (Diod.
None of the mole anchors had grappled.
When we come to pieces of very irregular shape, such as crank-shafts, anchors, trunnions, &c., we must resort to forging, except for purposes for which unforged castings are good enough.
The army and the prestige of the imperial tradition were, in fact, the two sheet-anchors that enabled the Habsburg monarchy to weather the storm.
Anchors to be allowed in full.
After that period a deduction of one-third shall be made, with the following exceptions: Anchors shall be allowed in full.
After four months at sea they dropped their anchors in Table Bay, where they remained for seven weeks before proceeding eastwards.
Other important industries include the making of boilers, steam-engines, locomotives, anchors, chain-cables, sailcloth, ropes, paper, woollen and worsted goods, besides general engineering, an aluminium factory, a flax-spinning mill, distilleries and an oil-refinery.
The walls thus supported no load but their own weight, and were tied to the inner cage formed by the wall columns, interior columns, girders, and floors by anchors arranged to provide for the shrinkage of masonry in drying out which always occurs to a greater or less extent.
These may be supported by bracket-angles attached to the columns with a system of anchors to tie them back; the material must be carried in such a manner as to make it independent of the general structure, and must be constructed as light as possible.
The stones extend a rod or two into the water, and then the bottom is pure sand, except in the deepest parts, where there is usually a little sediment, probably from the decay of the leaves which have been wafted on to it so many successive falls, and a bright green weed is brought up on anchors even in midwinter.
