In 1828, likewise, Victor Triboaillet de Saint Amand proposed to construct a telegraph line between Paris and Brussels. This line was to be a subterranean one, the wire being covered with gum shellac, then with silk, and finally with resin, and being last of all placed in glass tubes.
The square threads from which elastic webbing is made may be cut from these sheets, though sometimes the sheet is wound on an iron drum, vulcanized by being put into hot water, lightly varnished with shellac to stiffen it, then wound on a wooden cylinder, and cut into square threads. Boiling these in caustic soda removes the shellac. To make round threads, softened rubber is forced through a die.
This powder is extracted with petroleum spirit, and the solution shaken with water containing a trace of copper acetate. If rosin be present, the petroleum spirit will be coloured emerald-green. Borax, soda crystals, and ammonia are all used to dissolve shellac, and it may be asked: Which of these is least injurious to wool? and why?
To make up for its manifold imperfections the chef back in the kitchen had crowded it full of mysterious laboratory products and then varnished it over with a waterproof glaze or shellac, which rendered it durable without making it edible. Just to see that turkey was a thing calculated to set the mind harking backward to places and times when there had been real turkeys to eat.
The influence of a little sulphuric acid in the wool would be in the direction of neutralising some of the ammonia or soda, and shellac, if dissolved in the alkalis, would be to some extent precipitated on the fibre, unless the alkali, soda or ammonia, were present in sufficient excess to neutralise that sulphuric acid and to leave a sufficient balance to keep the shellac in solution.
Her skis, gathering dust in the attic, were brought down, cleaned and given the thin coat of shellac which, drying by morning, would put them in shape. A glance outdoors showed her that it had stopped raining and was clear and cold. There would be a good crust formed during the night. Shandon's note, which she read more than once, ran: "Dear Wanda Will you try to meet me at your cliff to-morrow?
But when shellac, sulphur, or spermaceti was interposed between the two spheres of one jar, while air occupied this interval in the other, then he found that the instrument occupied by the 'solid dielectric' takes more than half the original charge. A portion of the charge was absorbed by the dielectric itself. The electricity took time to penetrate the dielectric.
If black sealing-wax is required, lamp-black or ivory-black is stirred in. The fused material is then cast in moulds, from which the sticks are removed on cooling. That is how shellac may be coloured as sealing-wax, but it is a totally different method from that by which wool is dyed.
You can use No. 40 double cotton covered magnet wire, in which case you will have to shellac the tube and the wire after you get it on. Instead of leaving the wires outside of the tube bring them to the inside of it and then out through one of the open ends. This will cost you 25 or 50 cents. The Headphone.
All this can be done with the wheel jacked up, but if resting on the tire as suggested, the valve-stem is protected during the efforts to loosen tire. To put on a single-tube tire properly, the rim should be thoroughly cleaned with gasoline, and the new tire put on with shellac or cement, or with simply the lugs to hold.
