If an electric discharge was capable of operating a coherer across three thousand miles of ocean, then, certainly, the electric discharges from the wireless station four hundred feet away could produce coherer effects on the bad joints in the vat-wiring.
His great discovery, which died with him, was control over the direction and scope of the electric discharge. At the time, this was the unsolved problem of wireless telegraphy--as it still is to-day--but Emil Gluck, in his prison cell, mastered it.
From a room in Vallejo he sent his electric discharges across the Vallejo Straits to Mare Island.
His secret died with him, though it is now known that the French Government managed to get access to him and offered him a billion francs for his invention wherewith he was able to direct and closely to confine electric discharges. "What!" was Gluck's reply--"to sell to you that which would enable you to enslave and maltreat suffering Humanity?" And though the war departments of the nations have continued to experiment in their secret laboratories, they have so far failed to light upon the slightest trace of the secret.
Electric discharge installations (EDIs) with capacitive energy storage devices (reservoir capacitors) have found wide application in the development of new technologies for electric pulse treatment of materials and media (in particular, electro-erosion, electrohydraulic, magneto-pulse treatments, etc.) [1-8].
In this study,
electric discharge machining process was used for machining commercially available Inconel 625.
Of this, import of metal-cutting machine tools totaled US$549.04 million, up 36.1% and that for metal-forming machine tools amounted to US$80.61 million, down 21.8%, with the other major imports being
electric discharge machines; laser-cutting machines; machining centers; lathes; drilling, boring and milling machines; grinding machines; presses and shearing machines.
In this context, wire
electric discharge machining (WEDM) seems to be a better choice for machining the MMCs because it offers easy control and has capability of machining intricate complex shapes WEDM is a type of thermal advanced machining process capable of accurately machining the parts having varying hardness, complex shapes and sharp edges that are difficult to machine by other traditional and nontraditional machining processes.
The facility, which specializes in complex molds for the medical and industrial markets, has a new suite for two-shot molding that features high-speed CNC machining centers and
electric discharge machines with robotic tool-changing capabilities.

In response to rising demand for its
electric discharge machines in the Chinese market, Mitsubishi Electric Corp.
The devices, to be placed at regular intervals across the Japanese archipelago, catch electromagnetic waves emitted by lightning and estimate the direction of the
electric discharge and the time it will take for the electricity to reach the detector, the officials said.
