You will observe: that the terminals of the power transformer secondary coil which develops 10 volts are connected to the filaments of the oscillator tubes; that the terminals of the other secondary coil which develops 10 volts are connected with the filaments of the rectifier tubes; that the terminals of the third secondary coil which develops 550 volts are connected with the plates of the rectifier tubes; that the pair of filter condensers are connected in parallel and these are connected to the mid-taps of the two filament secondary coils; that the reactance coil and the third filter condenser are connected together in series and these are shunted across the filter condensers, which are in parallel; and, finally, a lead connects the mid-tap of the 550-volt secondary coil of the power transformer with the connection between the reactor and the third filter condenser.
It is easy, for instance, to construct a transformer capable of giving, when operated from an ordinary alternate current machine of low tension, say 50,000 volts, which might be required to light a highly exhausted phosphorescent tube, so that, in spite of the high potential, it is perfectly safe, the shock from it producing no inconvenience.
On the other hand, it may be pointed out to our mechanists who believe in mechanism to the bitter end, that even if man can be described entirely as a mere transformer of energy, there is no reason why he cannot also be described as a transformer of energy plus someone who makes use of the transformer and of the energy transformed.
She was undergoing the change that comes over each of us as soon as we yield our hearts to the strange influence that fascinates them. We have been told that "Love is a great transformer," and if we had never heard it we would have found it out for ourselves.
There are two ways to set up the sparks and these are: with an induction coil, or spark-coil, as it is commonly called, and with an alternating current transformer, or power transformer, as it is sometimes called.
When the electrodes are connected in series with the primary coil of a transformer and a source of direct current having a potential of 40 to 110 volts, bubbles of gas are formed on the end of the platinum, or alloy anode, which prevent the current from flowing until the bubbles break and then the current flows again, in this way the current is rapidly made and broken and the break is very sharp.
Jan found a cardboard roll that had once held paper towels. Rick cut off about six inches of it and proceeded to wind it with wire from the transformer. He wound evenly and tightly, until the roll was full of wire. Then he stabbed a small hole in each end of the roll and pulled the wires through to hold the coil in position. The roll now a coil was tacked to the board with thumbtacks. Dr.
It would not do to make the tube up of small lengths, because there would be with ordinary frequencies considerable loss in the coatings, and besides, if coatings were used, it would be better to supply the current directly to the tube by connecting the coatings to a transformer.
Since the radio frequency transformer has no iron core the high frequency, or radio frequency oscillating currents, as they are called, surge through it and are not changed into low frequency, or audio frequency pulsating currents, until they flow through the detector.
Nevertheless, many deep-thinking men thought differently, and one contemporary, reviewing this subject in after years, said of Mr Maclaren's papers, that, "they prepared the way for the success of railway projectors." We have said that the steam locomotive the material transformer of the world our Iron Horse, had just been born.
