Abstract: A control system for a power distribution grid including an electrical distribution circuit includes a processor configured to perform operations including constructing a grid model comprising edges and nodes representing assets and transmission paths of the power distribution grid, generating an analysis of an operation of the power distribution grid over a predetermined time duration, determining a plurality of constraint violations based on the analysis of the operation of the power distribution grid within the predetermined time duration, generating a plurality of alterations to the power distribution grid, respective ones of the plurality of alterations resolving at least one of the constraint violations, selecting a first alteration of the plurality of alterations to the power distribution grid responsive to determining that the selected first alteration resolves at least two of the plurality of constraint violations, and autonomously implementing the first alteration to the power distribution grid.

Abstract: An economic, non-polluting vapor-phase system of extracting titanium values from titanium ore or slag comprises solubilizing titanium (in ore or slag) with sulfuric acid to form titanyl sulfate, hydrolyzing the titanyl sulfate to form titanium oxide hydrate, converting the latter to pigment, and recycling sulfuric acid for extracting titanium values from further ore or slag. Methodology and equipment are provided.

Abstract: Alkali-metal bisulfate is employed in a non-polluting and economically-feasible system for producing titanium dioxide pigment from titanium mineral or slag with recycling of alkali-metal bisulfate and ammonia.

Abstract: Lower monobasic or dibasic alcohols are produced by the following steps:a) reacting a starting material with a metallic halide (wherein the metal is in the higher of two possible valence states) to obtain a reaction product, a corresponding metallous halide (wherein the metal is in the lower of the two possible valence states) and hydrohalic acid, andb) reacting the reaction product of step (a) and hydrohalic acid with magnesium oxide to form the corresponding lower monobasic or dibasic alkanol;wherein the starting material for forming a lower monobasic alcohol is a lower alkane, from which the corresponding lower alkanol is obtained; and the starting material for forming a lower dibasic alcohol is either a lower alkanol or a lower alkene, from which the corresponding lower glycol is obtained. Two continuous fluidized-bed systems are provided for conducting the necessary reactions.

Abstract: Lower alkanols are prepared from corresponding alkanes by reacting the lower alkane with a metal halide to produce a lower alkyl halide which, in turn, is reacted with magnesium oxide to form the corresponding lower alkanol. A continuous fluidized-bed system is provided for conducting the necessary reactions.

Abstract: A hydrocarbon is converted to a higher-molecular-weight hydrocarbon having greater unsaturation in compact and efficient apparatus, which provides for recirculating materials in a continuous process.

Abstract: A fume exhauster device comprising first means for generating a first air current directed substantially axially toward the first means, and second means for generating a second air current concentrically surrounding the first air current and flowing in circumferential and axial directions away from the second means, the second means comprising a substantially annular exit opening defined at least along its outer periphery by a peripheral surface extending in axial direction for forming the second air current into a cylinder shroud the outer diameter of which is substantially equal to the outer diameter of the exit opening.

Abstract: An electrical pumping device comprising at least two coaxially rotatable pump impellers, at least two coaxial separate passageways, one impeller positioned within each passageway, pole support parts attached to each of said impellers, said pole support parts forming a part of at least one electromotor and distributed about the axis of rotation in a radially spaced relation.

Abstract: A self-driving and self-locking device for traversing the inner walls of channels enclosed on all sides, or for traversing the outer casing of structures with a substantially constant cross-section over their lengths, and for affixing itself thereon, which includes a frame, propulsive elements disposed on said frame and at least one drive means for said propulsive elements to produce movement in the desired direction of movement of said device, said propulsive elements being distributed about the outer or inner circumference relative to a longitudinal axis coinciding substantially with the direction of forward movement and adjustable with respect to the longitudinal axis in a substantially radial direction relative to said frame to adapt to the contact surfaces in the channel or on the elongated structure.
