Abstract: A self-regenerating liquid metal current limiter including solid metal electrodes for connection to an electric circuit to be protected and several compression chambers which are partially filled with liquid metal. The compression chambers are located one behind the other between the electrodes and are formed by pressure-resistant insulating bodies and by partition walls with connecting channels that are supported by the insulating bodies. The partition walls are provided with a plurality of connecting channels that are not arranged in a generally concent arrangement with respect to a substantially horizontal longitudinal axis of the current limiter, the axis extending in a direction perpendicular to the partition walls. The current limiter provides for various positions of use corresponding to a position of rotation of the current limiter about its longitudinal axis.

Abstract: A change-over type of testing equipment for non-utility power generators, etc., includes a current-passing tank through which is charged with a resistance liquid, a main electrode disposed in the tank so as to receive power from the non-utility power generator to be tested, a movable insulator located between the main electrode and the tank to regulate the quantity of the current passing from the main electrode to the tank, a pipe system to cool or filter the resistance liquid within the tank for feeding the liquid back to the tank, thereby recycling the liquid, and a feed pipe connected to the pipe system on the upstream side of the tank to feed the liquid into the tank. The feed pipe serves as a holding member for holding the main electrode inserted into the tank from above and as a power supply member for supplying power from the non-utility power generator to be tested to the main electrode.

Abstract: An electrode for level detection includes a detection electrode including conductor portions and resistor portions arranged and formed one after the other in a level change direction. An insulating coating layer is formed on either each conductor portion or each resistor portion. The insulating coating layer may be of a film having a property to repel a liquid to be measured.

Abstract: A membrane of an ionic pendant-containing, water-insoluble copolymeric poly(amino acid) composed of a first moiety derived from a first amino acid which gives a water-soluble poly (amino acid) with ionic groups of carboxyl and/or amino groups as the pendants to the molecule, e.g., glutamic acid, aspartic acid, lysine and ornithine, and a second moiety derived from a second amino acid which gives a water-insoluble poly (amino acid), e.g., leucine, alanine and methionine, in a specified molar proportion serves as a functional element of an electronic device such as a non-linear resistor capable of working in an aqueous medium and exhibiting a non-linear voltage-current relationship or a phenomenon of hysteresis in the voltage/current scanning.

Abstract: The water resistance load system which comprises a water resistor, which includes a cylindrical base electrode with a bottom for storing a predetermined quantity of water while water is circulated through the cylindrical base electrode and a cylindrical main electrode penetrating in an insulated state through the center of the bottom and extending into the base electrode, and an electrode water cooling unit, which includes a radiator through which warm water drained from the water resistor is passed to the water resistor, and a water spray tube, a fan and an air guide for spraying water to the radiator, air cooling the surface of said radiator by the latent heat of evaporation of the sprayed water, and guiding generated steam to be discharged into a space.

Abstract: A water heater for heating water in a casing by direct passage of current between a high tension electrode and a counter electrode both in contact with water in the casing. An electrically-insulating shield arranged between the electrode and the counter-electrode, is movable relative to the electrode and the counter-electrode for the purpose of varying the length of the current path between the electrode and the counter-electrode. Means is provided for decreasing the ratio of the areas available for the flow of water in the two regions respectively between the electrode and the shield and between the shield and the counter-electrode as the length of the current path is decreased by movement of the shield relative to the electrode and counter-electrode.

Abstract: A high-voltage hot water boiler includes a plurality of fluid heating units arranged parallel to each other. Each fluid heating unit includes a cylindrical housing which serves as a counter-electrode. Each housing is provided with a fluid inlet and a fluid outlet so that fluid to be heated can be conducted therethrough and the housing is supported so that the fluid flow path is closer to the horizontal than to the vertical. An electrode extending in the flow direction is provided in each housing for cooperation with the counter-electrode to electrolytically heat the fluid flowing through the flow path. A nozzle, which may be electrically conductive, is associated with the electrode to direct incoming fluid towards the latter. An electrically-insulating sleeve surrounds the electrode and is movable by an adjusting means both in and opposite to the flow of the fluid to modify the flow of current between the electrode and counter-electrode.

Abstract: In a polyphase liquid rheostat cells for separately accommodating adjustable electrodes with the cells filled with an electrolyte, covered at the top and open at one end face, are formed from electrically nonconducting plastic sheets which are welded together in a liquid tight manner with the welds arranged, at least in the zones which are subject to voltage stresses, so that they are adjacent only to external spaces which are free of liquid thereby preventing an electrical short circuit between cells of different phases in the case of a leak in the welded seam.
