101 MAIN ELECTRODE DEVICE OF WATER RESISTOR JP17102188 1988-07-11 JPH0221602A 1990-01-24 MATSUMOTO KESAFUMI
PURPOSE:To stabilize the measurement of output characteristics and to improve the measuring capability under severe conditions by providing an electrode water inlet port at the central top of the upper end of a semispherical part, providing electrode outlet ports at the outer surface of a bottom part at an equal interval, providing a main electrode comprising a hollow cylinder at the center of the bottom part, and coupling a cylinder sleeve having arc-discharge resisting property to the inner surface of a circular recess part at the upper end. CONSTITUTION:Electrode water is processed at constant temperature and conductivity during circulation. The electrode water is made to fall and supplied in the direction of arrows from the right upper part of a main electrode 10. Part of the water enters into the inside through an electrode water inlet port 11 at the center of the top end of the main electrode 10. The electrode water flows down in the direction of arrows along the inner surface of the main electrode 10 and cools the electrode. The electrode water is drained from electrode water outlet ports 12 in the vicinity of a bottom part 10c through gaps l in the direction of arrows. The holding part of an arc surface 10b at the outer surface edge of the bottom part 10c of the main electrode 10 is covered in a circular recess part 14a. A part where arc discharge is liable to occur mostly is not exposed to the outside. The bottom part 10c is always cooled with the electrode water which passes through the gaps l from the electrode water outlet ports 12. Therefore, generation of bubbles due to local concentrated heating at this part is prevented beforehand. The arc discharge due to insulation breakdown is suppressed as much as possible.

110 High voltage control devices US936971 1978-08-25 US4259593A 1981-03-31 Joseph M. Proud; James M. Auborn; R. A. Bessett
High voltage control devices are provided comprising a housing, an aprotic liquid contained within said housing, means for effecting heat exchange with said liquid, at least two spaced electrodes contained within said liquid and each of said electrodes extending from said housing. These devices find utility as variable resistors, circuit breakers, thermostats, optical triggering devices, acoustic pulse generators and the like.
111 Resistance heating system US26168072 1972-06-12 US3808400A 1974-04-30 CORNELLA E; CORNELLA T
An electric heating system for mounting in floors of building structures includes a pair of spaced tubular manifolds interconnected by a plurality of spaced tubular members positioned between the manifolds and in communication therewith. Each of the manifolds is provided with an electrode extending the length of the manifolds and the electrodes are operatively connected across a voltage source. An electrically conductive liquid of a predetermined electrical resistance fills the manifolds and tubular members and is in contact with the electrodes whereby heating current can be caused to flow through said liquid from one electrode to the other to produce heat. The tubular members are made of plastic material which will melt when exposed to high ambient temperature conditions, thereby causing liquid to drain from the system to shutdown the heating system by open circuiting the electrodes. A liquid reservoir communicates with the system for assuring sufficient liquid supply and for providing space to accomodate thermal expansion of the liquid in the system.
112 Method of fabricating composite superconductive conductor US3644988D 1969-11-12 US3644988A 1972-02-29 ANDERSON GLENN A
A ribbon-type multilayer composite superconductive conductor having a large surface area including internal surfaces exposed to the coolant. The internal passages are formed by winding a superconductive conductor on a first ribbon of conductive material disposed between and separating two outer ribbons of conductive material whereby in combination with said ribbons the space between adjacent turns of the superconductive conductor defines passages on both sides of said inner ribbon, the passages on one side preferably being disposed at an angle to the passages on the other side of the inner ribbon and the normal material intermediate the turns of the superconductive conductor providing a low-resistance shunt path in the event one or more turns are driven into the normal state.
