Silver-soldering requires the use of a powerful blow lamp or gas-jet; ordinary soft soldering bits and temperatures are ineffective. Brazing is better still, but should be done by an expert, who may be relied on not to burn the metal. Getting the prepared parts of a boiler silver-soldered or brazed together is inexpensive, and is worth the money asked. Some Points in Design.
He returned to his adaptation of the Lawlor drive to the production of ball lightning. It was possible to wind coils. A certain percentage of the old condensers held a charge. He tapped the drive-unit for brazing current, and the drill-press became a die-stamping device for small parts. He built up the elements of a vacuum tube such as is normally found only in a landing grid control room.
And the houses oh, indescribably quaint and curious they were, with their fronts an elaborate lace-work of intricate and beautiful wood-carving, and now and then further adorned with rude pictures of elephants and princes and gods done in shouting colors; and all the ground floors along these cramped and narrow lanes occupied as shops shops unbelievably small and impossibly packed with merchantable rubbish, and with nine-tenths-naked natives squatting at their work of hammering, pounding, brazing, soldering, sewing, designing, cooking, measuring out grain, grinding it, repairing idols and then the swarm of ragged and noisy humanity under the horses' feet and everywhere, and the pervading reek and fume and smell!
First, in view of the fact that in the operation of brazing the copper may be seriously injured, to use solid drawn tubes. This appears fairly to meet the main dangers incidental to brazing; but as solid drawn pipes of over 7 inches diameter are difficult to procure, it hardly meets the case sufficiently. Secondly, to use electrically deposited tubes.
Every phrase appeared eloquently to illustrate and tell aloud the great burst of passionate fervour, felt to be with serious activity glistening, sparkling around, in painting and in decorative device. It was, as it were the unition, the brazing together of these serious impinging forces, and re-fusing them with fresher melody, newer vital ecstasy.
"And I tell you, Baudermann, that you're mistaken!" insisted one, evidently a foreman. "I told you to work in the brazing department. What do you want to try to force your way into the heavy casting department for? Especially when we're doing one of the biggest jobs that we ever handled making the new Swift cannon." "Oh, iss dot vot vas going on in dere?" asked the man addressed as Baudermann.
No regulator can be relied on for absolute precision, if worked up to its maximum possible capacity. Among other applications of a long narrow flame of high power, may be mentioned the brazing of long lengths of tube, in fact the application of flames of this form, with and without a blast of air, for different temperatures, are almost endless.
On the other side of the room was arranged a fairly complete chemical laboratory with several retorts, and an oxyhydrogen blow-pipe capable of developing the powerful heat used in the melting and brazing of metals. Beneath the benches were piled automobile supplies of every kind. "You know how to use all these machines, Jim?" she asked in wonder.
"Hum," said Father, when he had looked the Engine over very carefully. The children held their breaths. "Is there NO hope?" said Peter, in a low, unsteady voice. "Hope? Rather! Tons of it," said Father, cheerfully; "but it'll want something besides hope a bit of brazing say, or some solder, and a new valve. I think we'd better keep it for a rainy day.
