Abstract: A mixture of intermediate products including a carboxylic salt of 3,4,5-trimethoxybenzoic acid (TMB acid) and a dimethoxy benzoic acid derivative of such salt further containing an oxygen anion in the 3,4, or 5 position is prepared by initially reacting hydrolyzable tannin with a methylation agent in an alkaline medium under methylation conditions to form methylated tannin and thereafter hydrolyzing the methylated tanning by reaction thereof with a hydrolysis agent under alkaline hydrolysis conditions. The resulting reaction mixture is then methylated to form a reaction mixture containing methyl 3,4,5-trimethoxybenzoate and a salt of 3,4,5-trimethoxybenzoic acid. TMB acid can be formed in high yield by conversion of both the methyl ester thereof and the salt thereof. Such conversion can be effected by hydrolyzing the reaction mixture followed by acidification thereof.

Abstract: A process for ionization-effected removal of alkali composition from an ultrahigh temperature gaseous mixture containing the composition in vapor form is described. A flow of the hot gaseous mixture is conducted through a flow-through network in intimate contact with a metalliferous surface having a work function of at least 5.3 electron volts. The mixture heats the surface to the requisite temperature for effecting substantial alkali metal ionization. The resulting ions are removed by passing the resulting mixture containing same along a flow path through the lines of force of an electrical field of sufficiently low voltage to avoid both glow discharge and breakdown discharge. The lines of force extend to an electrically conductive ion-collection surface maintained at a sufficiently low temperature such that the ions are retained on the latter surface as a condensed phase.

Abstract: Disclosed is a solution including an aromatic bis (ether dicarboxylic acid) component, an organic diamine component and a solvent system including a water-soluble organic solvent component, which may be a dipolar aprotic solvent or a monoalkyl ether of ethylene glycol or of diethylene glycol, and optionally water. The solution may be coated on a substrate and polymerized to form high quality polyetherimide coatings.

Abstract: An improved arrangement for feeding a cool liquid into a pressure vessel and mixing the fed liquid with hot vessel-contained liquid includes an ejector thermal sleeve within an inlet nozzle. An upstream portion of the sleeve sealed to the nozzle surrounds a supply line through which a main feed flow is conducted to a sparger outlet port in the vessel. Cool leakage liquid flow is confined within the sleeve and ejected from an ejector chamber formed around the port by a downstream portion of the sleeve. The leakage liquid is ejected by and with the main feed flow away from the nozzle whereby thermal cycling and cracking thereof are substantially reduced.

Abstract: A process for separating particulate matter from a contaminated gaseous medium includes employing a swirling substantially contaminant-free gaseous medium between a zone for introducing the contaminated medium into a cyclonic separator zone and a product gas exhaust zone which extends into the separation zone. Apparatus suitable for carrying out the process is also described.

Abstract: A cross-ply composite flywheel is provided with a rim portion of circumferentially wound fibers impregnated with a binder. The density-to-stiffness ratio of the rim portion is of a value substantially less than the density-to-stiffness ratio of the cross-ply central portion of the flywheel. The strength of the flywheel is enhanced and only a minimum contribution is made to the weight of the flywheel.

Abstract: An improved method is described for solvent casting ultrathin non-porous methylpentene polymer films. The casting solution comprises methylpentene polymer or a mixture thereof with organopolysiloxane-polycarbonate copolymer dissolved in a solvent system and is characterized by being able to spontaneously spread over the surface of the liquid casting substrate. In a preferred embodiment, large-area films less than 200 Angstroms in thickness may be repeatedly formed. The solidified films remain relatively free of tensile stress during formation. The casting solution is deposited in a narrow, longitudinally-extending defined region at the surface of the casting substrate. The surface area and perimeter of the defined region are enlarged over the surface of the casting substrate in a manner whereby the casting solution is moved relative to the casting substrate and, after desolvation, the polymer film formed remains stationary relative to the casting substrate and relatively free of tensile stress.

Abstract: An improved extrusion apparatus and process are described for the preparation of a rod-like body from a coal-containing particulate mixture. Improvements are disclosed for depositing lubricant directly onto the outer surface of the forming body as it is passed into a die received over a discharge portion of the extruder barrel. Reductions in requisite power input to the extruder are thereby effectuated.

Abstract: An improved method for removing a component from a fluid mixture by transport of the component through an immobilized liquid membrane is described. The method includes introducing fresh membrane liquid into a first region of the membrane to effect emission of at least partially deactivated liquid from a second region of the membrane, thereby restoring or maintaining the separation efficiency of the membrane. Also described is an improved packaged membrane system including a plurality of at least partially spaced immobilized liquid membranes disposed in generally parallel surface-to-surface array to define both a first group of flow volumes and a second group of flow volumes alternating between the first group. Screens for spacing apart adjacent membranes are disposed in each of the flow volumes of at least one of the flow volume groups. Frames define the periphery of the flow volumes and flow passages provide separate access to and egress from the flow volumes in the two groups.

Abstract: Disclosed is a solution consisting essentially of a liquid ether solvent and dissolved therein a polyetheramide-acid-imide prepared by reacting at least one aromatic bis(ether anhydride) with at least one organic diamine. Also disclosed is a process for preparing the solution wherein the reaction is carried out in the ether solvent. The solution may be employed as a wire coating enamel.

Abstract: A sealing bar is provided for each gap between adjacent shroud plates to form part of the coolant recovery system of an open-circuit, liquid-cooled gas turbine. The undersides of the edges of the shroud plates at each gap are chamfered and a small cylindrical bar is supported in the recess provided thereby. Centrifugal force urges the bar into sealing engagement with the chamfered surfaces.

Abstract: Disclosed are an improved method and apparatus employing at least one immobilized liquid membrane separated from a liquid sweep by a gas-permeable barrier for removing a gaseous component from a gaseous mixture. The improvements include use of one or more liquid-filled passages extending through the gas-permeable barrier to effect diffusive transfer of active carrier species from the liquid sweep into the membrane, thereby maintaining the separation efficiency of each membrane. In a preferred embodiment, the improvements are applied to removal of hydrogen sulfide from mixtures thereof with carbon dioxide as found in gasified coal.

Abstract: The presence of antimony improves the magnetic properties of silicon-iron. Weld brittleness is reduced in addition to improving the magnetic properties by both adding antimony and lowering the sulfur content.

Abstract: Resistors disposed for vaporizing vapor-trap liquid coolant are individually connected in series with each of the high-aspect-ratio current leads connected to a superconductive coil of an intermittently operable electromagnetic machine. The portion of each lead extending from a coolant vapor return duct (through which the leads enter the machine) and terminating within the coil chamber is of hollow structure. The terminal length of each such portion is turned radially outward and its open outer end is submerged in the pool of liquid coolant in the chamber. The vapor traps are individually defined by liquid coolant in the hollow terminal length of each lead. Coolant vaporized in each trap flows in lead-cooling relationship with the corresponding hollow lead portion.
