But the whole of his theory seems fantastic to me. The facts concerning Davidson stand on an altogether different footing, and I can testify personally to the accuracy of every detail I have given. The chief attendant of the three dynamos that buzzed and rattled at Camberwell, and kept the electric railway going, came out of Yorkshire, and his name was James Holroyd.

By placing one end of a conducting circuit on the axis of the disc, and the other end on its circumference, he succeeded in drawing off a continuous electric current generated from magnetism, and thus produced the first dynamo. This was in 1831. Faraday produced many other dynamos besides this simple disc machine.

Sixth To design efficient dynamos, such not being in existence at the time, that would convert economically the steam-power of high-speed engines into electrical energy, together with means for connecting and disconnecting them with the exterior consumption circuits; means for regulating, equalizing their loads, and adjusting the number of dynamos to be used according to the fluctuating demands on the central station.

It looked like business from cellar to attic an amazing little place to find in an out-of-the-way village. The ground-floor rooms contained benches and apparatus, the bakehouse and scullery boiler had developed into respectable furnaces, dynamos occupied the cellar, and there was a gasometer in the garden. He showed it to me with all the confiding zest of a man who has been living too much alone.

While the engines were not directly coupled to the dynamos, it was a curious fact that the piston speeds and number of revolutions were what is common to-day in isolated direct-coupled plants. In the dozen years following Mr.

Suddenly a ridiculous noise begins to make the air tremble; the dynamos of the Agencies have been put in motion, and ladies in green spectacles arrive, a charming throng, with guidebooks and cameras. The tourists, in short, are come out of their hotels, at the same hour as the flies awake. And the midday peace of Luxor has come to an end.

The fire-control refused to act, the wires and speaking-tubes were destroyed, and each gun had to depend on itself. The electric installation had been put out of commission on the Louisiana by a shell bursting through the armored deck and destroying the dynamos.

''Tis only one o' them tin Turkish rattle-traps, said Bill with a pitying air. 'The old man'll slap a tin fish into her afore she knows what's hit her. As he spoke, the engines were already quickening, and G2 had begun to glide away at the top speed of her powerful electrics. The deep hum of the dynamos filled the long interior, and on every face was a look of eager expectancy.

At the generating station at Menlo Park four Z dynamos of 110 volts were used, connected two in series, in multiple arc, giving a line voltage of 220. "The motor was located in the front part of the locomotive, on its side, with the armature shaft across the frames, or parallel with the driving axles.

Immense steam turbines directly coupled with dynamos transform this power into electricity, and all of the machinery in the tractor and the body plants is run by individual motors from this electricity. In the course of time it is expected that there will be sufficient electricity to run practically the whole Highland Park plant, and we shall then have cut out our coal bill.
