There are several large tobacco factories, flour mills, boot factories, sugar refineries, tanneries, tallow works, meat-preserving, glue and kerosene-oil factories and soap works.
The principal manufactures are in iron, leather and skins; there are glue works and fire-brick works.
Rigid leathery leaves are fixed by means of glue, or, if they present too smooth a surface, by stitching at their edges.
But in a majority of cases the work of building is done by means of paste and glue only, so that the result lacks durability.
Those pieces are connected at theii joints or surfaces of mutual contact, either by simple pressure and friction (as in masonry with moist mortar or without mortar), by pressure and adhesion (as in masonry with cement or with hardened mortar, and timber with glue), or by the resistance of fastenings of different kinds, whether made by means of the form of the joint (as dovetails, notches, mortices and tenons) or by separate fastening pieces (as trenails, pins, spikes, nails, holdfasts, screws, bolts, rivets, hoops, straps and sockets.
The less robust species, such as Sphacelaria scoparia, which do not adhere well to paper, may be made to do so by brushing them over either with milk carefully skimmed, or with a liquid formed by placing isinglass (4 oz.) and water (11 oz.) in a wide-mouthed bottle, and the bottle in a small glue-pot or saucepan containing cold water, heating until solution is effected, and then adding i oz.
KoXXa, glue, and root yevof yevv6.aav, to produce, yiyvEo Oat, to become), the ground-substance of bones and tissues, is decomposed by boiling water or on warming with acids into substances named gelatin, glutin or glue.
Immersed in cold water gelatin does not dissolve but swells up; it dissolves readily in hot water, forming, according to the quantity present, a thick jelly which solidifies to a hard mass on cooling (the " glue " of the woodworker), or a thin jelly (used in cookery).
"Fibroin " and silk-glue or sericin occur in natural silk fibres.
The culture of such algae may prove of economic importance; gelatine, glue and agar-agar would be valuable by-products.
Chemical manures, glue, gelatine, brushes, chocolate and candles are also produced.
The town is one of the most prosperous in the duchy, and has machine works, foundries, tanneries, sawmills, breweries, distilleries, and manufactories of tobacco, glue, candles and soap. There is also a considerable trade in wool, corn, wood, butter and cattle, and an annual cattle show and horse races are held.
Erith has large engineering and gun factories, and in the neighbourhood are gunpowder, oil, glue and manure works.
1 Includes manufactories of glue, tallow, soap, perfumery, fertilizers, soda, &c.
They are coated internally with glue, and painted in the well-known colours, blue staves and white heads.
Some have supposed that certain chemical properties of which the Nile water was possessed acted as a glue or cement to cause the two layers to adhere; others, with more reason, that glutinous matter contained in the material itself was solved by the action of water, whether from the Nile or any other source; and others again read in Pliny's words an implication that a paste was actually used.
To form a roll the several sheets «oXX, F .cara, were joined together with paste (glue being too hard), but not more than twenty sheets in a roll (scapus).
Fibroin is insoluble in water, acids and alkalies; silk-glue resembles gelatin in its solubility, but it is less readily gelatinized.
The articles are first fashioned by joining the soft material; they are then varnished, and afterwards cured in ovens heated to about 135° C. The fine vulcanized " spread sheets " are made by spreading layers of indiarubber solution, already charged with the requisite proportion of sulphur, on a textile base previously prepared with a mixture of paste, glue and treacle.
He turned his shop into a furniture factory; soon sold this and for a short time was engaged in the grocery business on the site of the present Bible House, opposite Cooper Union; and then invested in a glue and isinglass factory, situated for twenty-one years in Manhattan (where the Park Avenue Hotel was built later) and then in Brooklyn.
Though the animals have an oral siphon, they do not carry ovisacs like the siphonostomous copepods, but glue their eggs in rows to extraneous objects.
For use with wood which is exposed to moisture, as in the case of wooden cisterns, a mixture may be made of 4 parts of linseed oil boiled with litharge, and 8 parts of melted glue; other strong cements for the same purpose are prepared by softening gelatine in cold water and dissolving it by heat in linseed oil, or by mixing glue with one-fourth of its weight of turpentine, or with a little bichromate of potash.
The blood is converted into clarifying material, the entrails are used for sausage coverings, the hoofs and small bones furnish the raw material for the manufacture of glue, the large bones are carved into knife handles, and the horns into combs, the fats are made to yield butterine, lard and soap, and the hides and hair are used in the manufacture of mattresses and felts.
The total factory product in 1905 was valued at $6,920,984, of which the canning and preserving of fish represented $4,068,571, and glue represented $75 2, 00 3.
Other industries of a semi-chemical character are candle-, soap-, glue-, and perfume-making, and the preparation of india-rubber.
The addition of a little of the acid to glue renders it more tenacious; skins to be used for making leather do not undergo decomposition if steeped in a dilute solution; butter containing a small quantity of it may be kept sweet for months even in the hottest weather.
For statuary, and "undercut" work generally, an elastic mould - of glue and treacle (80: 20 parts) - may be used; the mould, when set, is waterproofed by immersion in a solution of potassium bichromate followed by exposure to sunlight, or in some other way.
Cements such as marine glue are solutions of shellac, india-rubber or asphaltum in benzene or naphtha.
Norwood's manufactories include printing-ink and glue factories, tanneries, an iron foundry, and the printing-presses and binderies of J.
The city is the most important leather manufacturing centre of New England: in 1905 the value of the leather product was $2,851,554, being 61.3% of the value of all factory products ($4,654,067); other manufactures are chemicals, leather-working machinery, boots and shoes, glue and cotton goods.
For joiners' work, however, it is well adapted, and glue adheres strongly to it, though nails do not hold well.
