A 'purse' seine is a form of fishing net that is paid out around a school of fish, like a cylinder with no top or bottom. When drawn in, the bottom closes, forming a bag from which the fish cannot escape. Figure 1 in this illustration shows the separate parts of the purse seine: A and J, arms of the net; B and I, wings; C, D, K, and L, border of stout twine; F, bailing piece (or bunt); E and G, sides; H, under. Figure 2 shows a diagram of the form a a purse seine spread in the water.

This illustration shows a cross-section of a modern flour mill. Wheat is received in bin a, and first passes to the separator b, where it falls over vibrating screens, c, c, and a current of air draws light rubbish through pipe e to fan d. Next, in scourer f, it passes through revolving beaters, and meets a current of air. In the brush g, revolving brushes further clean and polish the wheat, which then passes to the 'cylinder' h. This revolving cylinder has grooves which pick up any small seeds, carrying them around until near the top of its revolution they drop into trough k and discharge by l at n, while the wheat grains too large for the grooving to affect, fall into the trough m, and are carried by the elevator p to the 'first break rolls', o. Here the wheat is partly crushed by rolls q, q, and passed to the 'scalper' r. Here, revolving brushes and beaters force the small particles through the fixed cage to the shoot s, while the larger are delivered at the end of the cage and pass to the second pair of rolls, t, and the second scalper, u. The coarse particles from u, chiefly bran, pass through a third set of rolls, v, and then to the 'bran duster', w, a cylinder where revolving brushes clean all flour from the bran and force it through perforations towards shoot x, the bran being delivered at y. The flour is carried by elevator p' to the 'reel' z, a finely perforated cylinder which revolves rapidly, an the finer part passes by shoot s' to the 'centrifugal' u'; the coarser part delivered at the end of the cylinder, passes to the 'purifier' r', where a current of air removes light dust as it travels over a moving sieve, and thence to a set of rolls at t' for further reduction, after which it is delivered to the centrifugal u'. This is a revolving drum, covered with silk, through which the flour is thrown by centrifugal force, and is delivered finished at v', the offals passing out at the end of the drum to the shoot w'.

A gabion is an open cylinder made of brushwood, canvas, wire-netting, or iron bands used in fortification. Filled with loose earth, gabions are placed on end, in tiers, to form a wall behind which earth can be piled. They are usually constructed on location and made up of whatever materials are on hand.

In making sheet glass, a very large lump of molten glass is gathered on the rod as is shown at (a). This mass is rolled on an iron slab, expanded (b) by blowing down the pipe, and further manipulated by rolling on the slab, reheating at the mouth of the furnace, re-blowing, and allowing the soft mass to hang downward. if the glass is to be used for windows, the blower has a cave in the floor about 8 ft deep, and in this hole he works the glass until he has a cylinder (c), which he swings backward and forward, holding onto the pipe. The cylinder is then blown to a length from 4 to 8 ft, according to the size of the window desired. It becomes very thin and chills rapidly. The blower then takes a second lump of hot glass, pulls it out to a string, winds it around each end of the cylinder (d), and cracks both ends off. A piece of wet iron is next drawn along the cylinder in the direction of the its length, as indicated by the dotted lines in (d). A crack follows the wet iron, and the detached cylinder opens a little at the long crack (e). A slight reheating, and opening out in a flattening kiln, serves to convert the split cylinder into a sheet.

After the softening process in the manufacturing of jute, the fibers are about six feet long, and are passed onto the breaker card, where they are reduced in length, finely divided, thoroughly mixed, cleared of impurities, and laid in parallel order. The chief features of the card are a cylinder about four feet in diameter covered with wooden staves filled with steel teeth, and around this cylinder a number of smaller cylinders, known as strippers and workers, also covered with steel teeth. The jute fibers are carried around the large cylinder, being finely divided by the workers and strippers in their course. A doffer roller then strips the elongated lap from the main cylinder and sends it down a broad channel, which compresses it to a strand or sliver about four inches wide. Twelve of these slivers are then fed into the finisher card, which is similar to the breaker, but has finer teeth, and are drawn out into a finer, smoother strand.
