Abstract: A narrow gap arc welding process comprises steps of defining a narrow gap between a pair of members to be welded arranged so as to face each other at a predetermined distance, feeding a consumable electrode into a guide cylinder which is movable along the narrow gap, and generating electric arc between the tip of the consumable electrode and the members to be welded to unite them with each other, wherein the consumable electrode, while being deformed plastically to have a wave-like pattern with a pitch of about 10 to 30 mm and a molding width of about 2 to 5 mm depending on welding conditions, is fed into the narrow gap with the direction of the molding width being in line with the direction of the width of the narrow gap and the direction of the tip of the consumable electrode being changed so as to point out one after the other facing edge of the members to be welded alternately at a high frequency. Also, an apparatus for practicing the process is described.

Abstract: A shaped body of a refractory or other functional inorganic compound of a metal, e.g., borides, carbides, silicides, etc. of titanium, zirconium, niobium and the like in a plate-like form can be prepared by an in situ reactive sintering method in which a metal-made flat reaction capsule is filled with a mixture of the reactant powders to form a powder compact which is ignited at a periphery while the capsule is under hydraulic compression so that the exothermic reaction is efficiently and almost instantaneously propagated within the plane of the plate-like powder compact. The liquid compression medium communicates to an accumulator filled with a compressed gas so that the otherwise unavoidable sudden pressure decrease due to the shrinkage of the powder compact can be compensated by the expansion of the compressed gas to keep constancy of the pressure.

Abstract: A process of treating meal containing vegetable proteins is disclosed. This process includes the step of extracting the metal with a suitable aqueous solvent in which the vegetable proteins are soluble to obtain an extraction solution. The solubility of the dissolved protein in the extraction solution is then adjusted to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution. The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing. Each of the protein fractions is then suitably dried to recover the proteins.

Abstract: The organopolysiloxane composition is useful as a potting or encapsulating material having a gel-like consistency for protecting electronic components even at an extremely low temperature as is encountered in the space industry. The composition is basically of the type in which crosslinks are formed by the addition reaction between silicon-bonded vinyl groups in an organopolysiloxane and silicon-bonded hydrogen atoms in an organohydrogenpolysiloxane but the outstanding cold resistance of the gel-like material obtained from the composition is imparted by incorporating specific silethylene-containing units of the unit formula OSiMe--CH.sub.2 CH.sub.2 --SiMe.sub.2 O.sub.0.5 into the organopolysiloxane in a specified molar content.

Abstract: The photosensitive composition, which is suitable as a photoresist material in fine patterning works for the manufacture of semiconductor devices, contains, as a photoextinctive agent, a combination of an alkali-insoluble dye and an alkali-soluble dye each having absorptivity of light in the wavelength region from 230 to 500 nm in a specified amount and in a specified ratio between them. By virtue of the formulation of combined dyes, the undesirable phenomenon of halation by the underlying aluminum coating layer on the substrate surface is greatly decreased so that patterned resist layer obtained with the composition is a high-fidelity reproduction of the original pattern even in a submicron range of fineness with good rectangularity of the cross sectional form of the patterned lines.

Abstract: A method of extracting components from particulate materials is disclosed. The method includes the steps of mixing the particles with a first extraction solvent to provide a slurry. The slurry is then passed through an extraction zone. A second extraction solvent is passed countercurrently to the slurry through the extraction zone. The second solvent has a different density from the first solvent and is substantially immiscible with the first solvent. This process is particularly beneficial for use in the extraction of ground oil-seed particles.

Abstract: A fermentation vessel comprises an outer shell, and an annular draft tube located within the shell and spaced therefrom to promote continuous circulation of fluids through said draft tube within said shell. The draft tube has an internal cavity located within its walls. The cavity is connected to a fluid supply conduit that extends externally of the shell. A plurality of discrete nozzles are disposed about the circumference of the tube and communicate with the cavity to permit egress of fluids from the cavity to the interior of the shell to promote circulation.
