Abstract: Systems and methods of diagnosing a communication system within an industrial machine. The method includes receiving, from the industrial machine, communication system data of the communication system of the industrial machine and determining whether the received communication system data indicates an occurrence of a communication system issue. The method further includes determining whether the received communication system data includes one or more dismissive parameters in response to determining that the received communication system data indicates the occurrence of the communication system issue. The method also includes analyzing the received communication system data to determine whether a remote resolution to the communication system issue is available and transmitting the remote resolution to a user associated with the industrial machine in response to determining that the remote resolution to the communication system issue is available.

Abstract: A chemical process for producing bulk quantities of an iron-silica gel composite in which particle size, form, and magnetic state of the iron can be selected. The process involves polymerizing an ethanolic solution of tetraethylorthosilicate, ferric nitrate and water at low temperature under the influence of an HF catalyst. The chemical and magnetic states of the iron in the resultant composite are modified in situ by exposure to suitable oxidizing or reducing agents at temperatures under 400.degree. C. Iron-containing particles of less than 200 .ANG. diameter, homogeneously dispersed in silica matrices may be prepared in paramagnetic, superparamagnetic, ferrimagnetic and ferromagnetic states.

Abstract: A co-precipitation synthesis of precursors to bismuth-containing ceramic superconducting materials is disclosed in which bismuth and at least one other approrpiate metal are dissolved in a non-aqueous acidic solvent, which are then recovered as a homogeneous dry powder. The mixed metal salts are co-precipitated from aqueous solution in the form of the corresponding homogeneous hydroxycarbonate precursor mixture by reaction with either sodium carbonate or potassium carbonate. The homogeneous precursor may be then converted to the BiCuSrCuO.sub.x ceramic by calcining the mixed hydroxycarbonate to a powder, compressing said powder into a green compact, sintering said green compact at a temperature of at least 750.degree. C., and cooling the ceramic material so produced at a controlled rate, preferably about 50.degree. C./minute.

Abstract: A process for producing any desired Ba/Ti mixture to be formulated as an amorphous solid which crystallizes at very low temperatures to yield a desired phase or phases is disclosed. The process yields products free of undesirable impurities and allows macroscopic production of certain phases in the baria-titania system, having exceptional high frequency dielectric properties, that were previously unattainable through solid-state high temperature production techniques.

Abstract: Refractory borides or carbides are prepared by contacting an alkali-metal ducible metal chloride or silicon tetrachloride with boron trichloride or carbon tetrachloride in an inert solvent in the presence of an alkali metal, the metal chloride or silicon tetrachloride and the boron trichloride or carbon tetrachloride being present in an amount about stoichiometrically equivalent to the boride or carbide to be prepared and the alkali metal being present in an amount about stoichiometrically equivalent to the amount of chloride in the metal chloride or silicon tetrachloride and the boron trichloride or carbon tetrachloride, until all chloride present has reacted with the alkali metal to form alkali metal chloride, separating the inert solvent to leave a solid residue containing a metal boride, silicon carbide or metal carbide precursor together with the alkali metal chloride, and calcining the residue while separating the alkali metal chloride until the precursor is converted to the refractory boride or carbide

Abstract: An isotopic starting material consisting of a mixture of chlorine-35 and chlorine-37 isotopic species of an isotopic compound having the formula CYClX, wherein Y is O or S and X is Cl or F, such as thiophosgene, is selectively isotopically enriched by means of a laser-induced photochemical reaction between selected chlorine isotopic species in the starting material and a dialkoxyethylene, such as diethoxyethylene. The method is carried out by irradiating with laser radiation, a gaseous mixture at a reduced pressure of the isotopic starting material and the dialkoxyethylene, until a stable reaction product is formed. The wavelength of the radiation is selected so as to selectively excite at least one but less than all of the chlorine isotopic species in the starting material, thereby causing the excited species to preferentially react with the dialkoxyethylene.

Abstract: A boron trichloride starting material containing both boron-10 isotopes and oron-11 isotopes is selectively enriched in one or the other of these isotopes by a laser-induced photochemical method involving the reaction of laser-excited boron trichloride with either H.sub.2 S or D.sub.2 S. The method is carried out by subjecting a low pressure gaseous mixture of boron trichloride starting material and the sulfide to infrared radiation from a carbon dioxide TE laser. The wave length of the radiation is selected so as to selectively excite one or the other of boron-10 BCl.sub.3 molecules or boron-11 BCl.sub.3 molecules, thereby making them preferentially more reactive with the sulfide. The laser-induced reaction produces both a boron-containing solid phase reaction product and a gaseous phase containing mostly unreacted BCl.sub.3 and small amounts of sulfhydroboranes.
