He showed me the smelter, where the quicksilver condensed in the coils and ran with its small luminous silver streams into the vats. He was called away momentarily by one of his men, leaving me standing there. I was alone; no one seemed in sight, or within hearing. In the shadow of the condensers I drew out my transmitter and called Hanley. I got him within a minute. "Chief!" "Yes, Phil.
If you have a short-wave set and plan to receive intermediate waves with it then loading coils and fixed condensers shunted around them affords you the way to do it, but if you prefer to buy a new receptor then the better way is to get one with bank-wound coils and variable condensers; this latter way preserves the electrical balance of the oscillation circuits better, the electrical losses are less and the tuning easier and sharper.
This condenser, which is shown at D, is made in two sizes, the smaller one being large enough for all ordinary wave lengths while the larger one is for proportionately longer wave lengths. These condensers cost $4.00 and $5.00 respectively. About Telephone Receivers. There are a number of makes of head telephone receivers on the market that are designed especially for wireless work.
All common water contains a certain quantity of air in solution, and this air recovers its elasticity when the pressure of the atmosphere is taken off, just as the gas in soda water flies up so soon as the cork of the bottle is withdrawn. Q. Is a barometer sometimes applied to the condensers of steam engines?
The double-engine; consisting of two engines, primary and secondary, of which the steam-vessels and condensers communicate by pipes and valves, so that they can be worked either independently or in concert; and make their strokes either alternately or both together, as may be required. The employment of a toothed rack and sector, instead of chains, for guiding the piston-rod.
And Terence Reardon laughed the short, mirthless chuckle of the man who knows. "Then," Matt continued, "the money should be spent " "In retubing her condensers," declared the engineer emphatically. "Do that an' do a good job on her, an' she'll have shteam enough for thim fine big ingines av hers on thirty-two ton a day, an' less. An' have a care would ye buy her until she ships a new crank shaft.
He was surprised to hear that glass condensers heated, and inquired whether this heating was due to flashes passing between the foil and the glass. Mr. A.P. Trotter said Mr. Ferranti informed him that the capacity of his mains was about 1/3 microfarad per mile, thus making 2-1/3 microfarads for the seven miles.
When this is done the plates will be positively charged alternately with every reversal of the current in which case there will be no break in the continuity of the oscillations set up and therefore in the waves that are sent out. The Operation of Rectifier Vacuum Tubes. The vacuum tube rectifier is simply a two electrode vacuum tube. The Operation of Reactors and Condensers.
The pulsating direct currents are then passed through a filtering reactance coil, called a reactor, and one or more condensers, and these smooth them out until they approximate a continuous direct current.
This is the same kind of a hot-wire ammeter already described in connection with the experimental set, but it reads to 5 amperes. The Grid and Blocking Condensers. Each of these is a fixed condenser of .002 mfd. capacitance and is rated to stand 3,000 volts. It is made like the aerial condenser but has only two terminals. It costs $2.00. The Key Circuit Apparatus.
