Abstract: An improved method for the recovery of para-aminophenol from crude solutions thereof such as obtained by the catalytic hydrogenation of nitrobenzene in an aqueous acid reaction medium. The method comprises neutralizing the cold, acidic solution containing the crude para-aminophenol whereby a very fine fluffy para-aminophenol precipitates. When an aromatic amine selected from the group consisting of aniline, mixed toluidines, ortho-toluidine, mixed xylidines, and mixtures thereof is admixed therewith an upper layer containing the para-aminophenol suspended in the aromatic amine forms when allowed to settle. A clear lower layer containing about 70 to 90% of the ammonium sulfate solution is separated and discarded. The upper layer which contains the aromatic amine and the para-aminophenol can be used as a source of para-aminophenol for producing para-aminophenol derivatives such as diaryl para-phenylenediamines.

Abstract: The effects of vertical perturbations of a gramophone disc record surface resulting from e.g. record warp and rumble are reduced by sensing the perturbations and compensating therefor by closed loop or open loop means. Thus a reference path adjacent the groove tracked by the main stylus may be tracked, e.g. by a supplementary stylus riding on the lands of the disc surface or photoelectrically. A reference path signal may then be derived by a reference path sensor 104, and this signal is then applied to a preferably closed loop servo 95, 98, 100, 112, 114, 97 which moves the disc 9 itself up and down to tend to null out the reference path signal. Alternatively the compensation is applied by causing the tone arm to track the reference path by a servo technique or by mechanical coupling within the cartridge or electrically by subtracting the reference path signal from the main stylus signal, or by a combination of such techniques. <IMAGE>

Abstract: The invention relates to a process for impregnating pine wood veneers by means of impregnating agent and subsequent drying of the impregnated veneers. As a result of impregnating solution being applied by rolling or spraying merely to the surface of the veneer, the wood veneer 11 which is lathed or cut out from the wood in question is impregnated, and this whilst the veneer is still damp and before its bordered pits have become closed, so that the impregnating agent, through diffusion, is distributed in the veneer through its cell walls, after which the veneer is heat-dried such that the moisture evaporates and the bordered pits of the cell walls are sealed. The present invention utilizes the fact that the cells of the lathe timber, as a result of the bordered pits, remain open for a certain period after lathing and allow highly concentrated impregnating solution of certain types, through chemiosmatic overpressure, to diffuse in to a surface depth of a few mm throughout the wood. The entire cell structure is left intact without mechanical damage and the agent is then fixed under heat in a subsequent drying process. A laminate of these veneers allows all the mechanical properties of the wood material to be preserved, whilst at the same time ensuring that the impregnation concentration is uniform throughout the whole of the cross section. As a result of this method, impregnated laminate is able to be made from otherwise unusable wood. Pressure-impregnated or surface- impregnated wood demonstrates inwardly diminishing concentration, even for normally impregnable wood types. <IMAGE>

Abstract: A shield (32) is disposed in spaced relationship to the exterior surface of the combustor liner (18) of a gas turbine engine and extends over a plurality of very small holes (28) formed in the combustor liner so as to regulate flow of air to these holes. A portion of the air flowing along the exterior surface of the combustor liner is diverted for reverse flow in the path (44) provided between the shield and the combustor liner. Larger holes (52) are provided in the liner at the point of reversal of the air so that dirt particles in the air, because of the centrifugal force acting thereon, tend to flow through them. A second group of larger holes (56) coiled any remaining dirt particles during a second reversal of air flow. The very small holes are thus protected against being plugged by the particles. <IMAGE>

Date May 2, 1996In joining an optical fiber containing twin cores to a corresponding optical fiber of standard type having a single core and having the same outer diameter, so that a core in the twin-core fiber is aligned with the core in the standard fiber, a conventional automatic splicing machine for optical fibers is used. The twin-core fiber is placed with its cores for instance located in a vertical plane. Then the fibers are spliced in a conventional manner with an alignment of the outer surfaces of the fiber ends and during the splicing procedure or from the finished splice the lateral offset of for instance the upper core of the twin-core fiber and the single core is determined. This can be carried out by capturing an image of the fiber splice in a heated state, when the splice is performed by fusion-welding. The determined offset value then gives the offset, which is to exist between the outer surfaces of the fiber ends for providing the correct alignment of the fiber cores. Hence, the splice region of the fibers is then removed and the fibers are spliced again, but this time with a suitable, calculated offset of the outer surfaces of the fibers.
