The collection was made up of Shipton's newly purchased, barely used, ice climbing gear, ropes, ice axes, pitons and various garments.
The industries of the town include cotton spinning and weaving, silk spinning, the manufacture of tobacco, ropes, metal-ware, furniture, &c. The market gardens of the neighbourhood are famous, and there is a considerable shipping trade by the river and the Ludwigskanal.
The chief industries of Grimsby are shipbuilding, brewing, tanning, manufactures of ship tackle, ropes, ice for preserving fish, turnery, flour, linseed cake, artificial manure; and there are saw mills, bone and corn mills, and creosote works.
From the widespreading roots string and ropes are manufactured in Lapland and Bothnia: the longer ones which run near the surface are selected, split through, and then boiled for some hours in a ley of wood-ashes and salt, which, dissolving out the resin, loosens the fibres and renders them easily separable, and ready for twisting into cordage.
Thrice Samson scoffingly told her how he might be bound, and thrice he readily broke the bonds with which she had fettered him in his sleep; seven green bow-strings, new ropes, and even the braiding of his hair into the frame of the loom failed to secure him.
There are manufactures of paper, hats, leather, ropes, porcelain, majolica, soap, spirits, and ornaments made of palm leaves and grasses.
Shipbuilding and the manufacture of ropes, paint and sails are industries.
It is a centre of the iron and steel industries, producing principally cast steel, cast iron, iron pipes, wire and wire ropes, and lamps, with tin and zinc works, coal-mining, factories for carpets, calcium carbide and paper-roofing, brickworks and breweries.
There are works for the manufacture of woollens and ropes, also tanneries, but it is as the central market of a large and fertile district that Carmarthen is most important.
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.
The ropes are supported between the rails and guided on curves by rollers and sheaves.
Tapering ropes, tail-ropes suspended from the cages, and other means of equalization, are also employed.
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.
Formerly hemp and also fibre ropes were commonly used.
Except in a few instances these were long ago superseded by ron-wire ropes, which in turn have p been replaced by steel because of its greater strength.
He smiled, enjoying it, then climbed through the ropes of the ring.
Not giving him a chance to argue, she ducked through the ropes and leapt to the floor.
For many years the best workshop travellers were those driven by quick running ropes; these performed admirable service, but they have given place to the more modern electric traveller.
Numerous patent ropes, some having wires and strands of special shapes, have been introduced with the idea of improving the wearing properties.
Hoisting ropes are weakened by deterioration and breakage of the wires, due to corrosion and repeated bending.
Ropes of tapering section may be used for great depths, but are not satisfactory in practice.
Sinking pumps, designed for use in shafts in process of sinking, are suspended by wire ropes so as to be raised before blasting and promptly lowered again to resume pumping.
The principal industries are the manufacture of sackings, ropes, bricks, coarse earthenware, terra-cotta, tobacco-pipes and leather.
It was in this lofty rock-girt hollow that the gladiator Spartacus was besieged by the praetor Claudius Pulcher; he escaped by twisting ropes of vine branches and descending through unguarded fissures in the crater-rim.
Machinery, cement, cordage, wire ropes, tobacco, leather, &c. are manufactured.
The arrangements for this purpose vary, of course, with the amount of work to be done with one fixing of the machinery; where it is likely to be used for a considerable time, the drum and brake are solidly constructed, and the ropes of steel or iron wire carefully guided over friction rollers, placed at intervals between the rails to prevent them from chafing and wearing out on the ground.
These are simply wire-ropes, from to 12 in.
Flat ropes of steel or iron wire were and are still used to a great extent, but round ones are now generally preferred.
In Belgium and the north of France flat ropes of aloe fibre (Manila hemp or plantain fibre) are in high repute, being considered preferable by many colliery managers to wire, in spite of their great weight.
Tapered round ropes, although mechanically preferable, are not advantageous in practice, as the wear being greater at the cage end than on the drum it is necessary to cut off portions of the former at intervals.
Ultimately also the ropes should be reversed in position, and this can only be done with a rope of uniform section.
The drum, when round ropes are used, is a plain broad cylinder, with flanged rims, and cased with soft wood packing, upon which the rope is coiled; the breadth is made sufficient to take the whole length of the rope at two laps.
One drum is usually fixed to the shaft, while the other is loose, with a screw link or other means of coupling, in order to be able to adjust the two ropes to exactly the same length, so that one cage may be at the surface when the other is at the bottom, without having to pay out or take up any slack rope by the engine.
For flat ropes the drum or bobbin consists of a solid disk, of the width of the rope fixed upon the shaft, with numerous parallel pairs of arms or horns, arranged radially on both sides, the space between being just sufficient to allow the rope to enter and coil regularly upon the preceding lap. This method has the advantage of equalizing the work of the engine throughout the journey, for when the load is greatest, with the full cage at the bottom and the whole length of rope out, the duty required in the first revolution of the engine is measured by the length of the smallest circumference; while the assistance derived from gravitating action of the descending cage in the same period is equal to the weight of the falling mass through a height corresponding to the length of the largest lap, and so on, the speed being increased as the weight diminishes, and vice versa.
In this method a third drum is used to receive a heavy flat link chain, shorter than the main drawing-ropes, the end of which hangs down a special or balance pit.
In Belgium it was tried in a pit 940 metres deep, where it has been replaced by flat hempen ropes, and is now restricted to shallower workings.
Ropes and Round steel wire-ropes, about 2 in.

When closed by the load the width is sufficient to allow it to enter a funnel-shaped guide on a cross-bar of the frame some distance above the bank level, but on reaching the narrower portion of the guide at the top the plates are forced apart which releases the ropes and brings the lugs into contact with the top of the cross-bar which secures the cage from falling.
The ropes are spaced laterally by the blocks B, B, B, B, which also serve to prevent them from slipping sideways.
In the former the main supporting member or members may be an arch ring or arched ribs, suspension chains or ropes, or a pair of girders, beams or trusses.
In suspension bridges the principal members are in tension, and the introduction of iron link chains about the end of the 18th century, and later of wire ropes of still greater tenacity, permitted the construction of road bridges of this type with spans at that time impossible with any other system of construction.
For erection a suspended platform was constructed on eight wire ropes, on which the chains were laid out and connected.
In length, and are grey-green in colour; on account of their tenacity of fibre and flexibility they have for centuries been employed for the making of ropes, sandals, baskets, mats and other articles.

In addition to these are the many small domestic industries, such as the making of straw hats, mats, baskets, pottery, ropes and rough textiles.
Solemn and gay dances were frequent, and a sport called the bird-dance excited the admiration of foreigners for the skill and daring with which groups of performers dressed as birds let themselves down by ropes wound round the top of a high mast, so as to fly whirled in circles far above the ground.
The industries of Pistoia include iron and steel works, especially manufactures of glass, silk, macaroni, woollens, olive oil, ropes, paper, vehicles and fire-arms. The word "pistol" is derived (apparently through pistolese, a dagger - dagger and pistol being both small arms) from Pistoia, where that weapon was largely manufactured in the middle ages.
The other industries, are chiefly fishing, shipbuilding and the manufacture of ropes and sails.
The town was noted for the manufacture of ropes and cables as early as 1213, and an act of parliament (21 Henry VIII.) shows that the inhabitants had "from time out of mind" made the cables, ropes and hawsers for the royal navy and for most of the other ships.
It has an important cloth industry, and manufactures of sugar, ropes, machinery and agricultural implements.
All over the forest spread lianas, or monkey-ropes, their usual position being that of immense festoons hanging from tree to tree.
The manufactures are not extensive, but the preparation of fish products, shipbuilding, weaving and distillery, with manufactures of paper, pottery, tobacco and ropes are carried on.
Square sunk into the blue ground; the diamantiferous rock was hoisted by bucket and windlass, and roadways were left across the pit to provide access to the claims. But the roadways soon fell in, and ultimately haulage from the claims could only be provided by means of a vast system of wire ropes extending from a triple staging of windlasses erected round the entire edge of the mine, which had by this time become a huge open pit; the ropes from the upper windlasses extended to the centre, and those from the lower tier to the sides of the pit; covering the whole mass like a gigantic cobweb.
12.) The buckets of blue ground were hauled up these ropes by means of horse whims, and in 1875 steam winding engines began to be employed.
If jump ropes or board games or ice cream turn out to have positive externalities—that is, if they help society—a subsidy could lower the prices of these items.
Our little boat confronted the gale fearlessly; with sails spread and ropes taut, she seemed to sit upon the wind.
Behind the guns were their limbers and still farther back picket ropes and artillerymen's bonfires.
The wagons escorted by the hussars drew up to the picket ropes and a crowd of hussars surrounded them.
There were trunks in the rooms, and hay, wrapping paper, and ropes were scattered about.
"But Shipton had two ropes," Cynthia said.
