61 High resistivity liquid/solid resistor US36600973 1973-06-01 US3845448A 1974-10-29 HADERMANN A; WATERS P; WOO J
A compact stable liquid-solid resistor having a large resistance to length ratio is disclosed. The range of resistivities is exceptionally wide because liquid and solid dielectrics are employed together.

65 Current transformer high voltage probe utilizing copper sulfate water resistor US265865 1981-05-21 US4438395A 1984-03-20 Charles R. McClenahan
A current transformer and copper sulfate water resistor are combined to provide a probe capable of measuring very fast, high voltage pulses. The resistor is connected in series with the primary winding of the current transformer and consists of an elongated plastic tube filled with an aqueous solution of copper sulfate. The series arrangement of resistor and current transformer primary winding is applied across the source of voltage to be measured and the current transformer secondary winding output is a function of the measured voltage. The current transformer secondary output is applied to and displayed on an oscilloscope.

68 Electrolytic resistor US743256 1976-11-19 US4112409A 1978-09-05 Jean Jacquelin
The invention relates to an electrolytic resistor comprising a water-repellent insulating tube through which there flows an alkaline solution containing a suspension of zinc. The positive end of the resistor has a metallic grid suitable for trapping the zinc particles, and the negative end has either an air electrode or a ring made of a metal having, more especially, high hydrogen supertension, this ring itself possibly having holes or projections suitable for promoting the progressive deposition of zinc dendrites. The invention is used in zinc-air storage cells.
69 Liquid resistor apparatus US3609626D 1969-03-18 US3609626A 1971-09-28 BEYRARD NORBERT ROGER
Liquid resistor apparatus in which electrically conductive liquid is transferred from a control chamber to a controlled chamber, thereby affecting the electrical resistance between electrodes in the controlled chamber, as a result of evaporation of liquid in the control chamber by control current passed therethrough, there being a liquid passage and a restricted vapor passage connecting the two chambers. The restriction in the vapor passage is set during operation and may be adjustable to govern the operating characteristics of the apparatus.

71 Liquid resistor cooling device JP2007072067 2007-03-20 JP2008235518A 2008-10-02 FUJIWARA HITOSHI
PROBLEM TO BE SOLVED: To provide a liquid resistor cooling device in which even if the liquid (electrolyte) of a liquid resistor is mixed with cooling liquid (cooling water) in a heat exchanger, the cooling liquid with which the liquid is mixed is prevented from being distributed. SOLUTION: The device includes an electrolyte circulating pump 40, a first plate type heat exchanger 41, a first cooling water circulating pump 42, a cooling liquid tank 43 for reserving tap water (first cooling water), a second cooling water circulating pump 44, a second plate type heat exchanger 45, and a third cooling water circulating pump 46. The electrolyte of a liquid resistor 31 is not cooled directly by purified water (second cooling water) of a purified water reservoir 80 but cooled indirectly via tap water (first cooling water) of the cooling water tank 43 provided between the first plate type heat exchanger 41 and the second plate type heat exchanger 45.

PURPOSE:To obtain a stable and high voltage dividing ratio without impairing pulse responsiveness by providing a pair of intermediate divided electrodes kept at the same potential with each other on both sides of at least one intermediate electrode to divide electrolyte chambers. CONSTITUTION:An insulating cylinder 12A sealed with an electrolyte 1 is divided by at least one intermediate electrode 15 kept at the same potential as the potential of the low-voltage electrode 4 to constitute at least the two electrolyte chambers 11A, 11B. A pair of the intermediate divided electrodes 16A, 16B having the same potential are provided on both sides of the electrode 15, by which the primary voltage divider 10 to deliver the voltage of the electrode 16A as its output is constituted of the high-voltage electrode 3 and the electrode 15 facing this electrode via the liquid chamber 11A. The secondary voltage divider 20 is constituted of the electrode 4 and the electrode 15 facing this electrode 4 via the liquid chamber 11B. The voltage divider of the multistage type is constituted of only the electrolyte resistance in such a manner, by which the voltage divider having the excellent pulse responsiveness and large voltage dividing ratio with less inductance is obtd. The electrolyte 1 filled in the plural electrolyte chambers 11A, 11B flows convectionally through a through-hole 25 and, therefore, the temps. are leveled off and the voltage dividing ratio is stabilized.
