Abstract: Described herein is a process for the conversion of hydroperoxides, present in allyl-alkyl ethers to products including α,β-unsaturated aldehydes and for reducing such α,β-unsaturated aldehydes to alcohols prior to the use of the ether as a feedstock in a hydroformylation reaction to produce the corresponding ether aldehyde. The process involves contacting the ether with a metal hydride, either in aqueous solution and/or by means of an ion exchange resin. Such treatment decomposes the hydroperoxides and then reduces their α,β-unsaturated aldehyde decomposition products, thereby reducing the catalyst inhibition period present in the hydroformylation reaction which is observed when such α,β-unsaturated aldehyde impurities are present.

IPC: F16K39/04

Abstract: The invention relates to a hydraulic control valve comprising a housing with a housing bore (2) formed therein, a control piston (3) being guided in said housing bore for sliding displacement between a neutral position (n) for zero-pressure through-flow and at least one control position (I, II), and further comprising a pressure inlet (6) opening in said housing bore (2), a through-passage (8) in said control piston (3), and a discharge outlet (7) communicating with said pressure inlet via said through-passage in the zero-pressure through-flow position. In a control valve of this type, particularly if employed in a high pressure hydraulic system, displacement of the control piston from a control position to the neutral position is hampered by unsatisfactory pressure compensation. In accordance with the invention, this undesirable effect is avoided by forming substantialy diametrally opposite said discharge outlet (7) a relief area (9, 9', 16, 17, 18, F26) compensating at least the effective area of said discharge outlet and being of substantially the same size as the discharge outlet and subjected to the same pressure as the latter. For ensuring effortless displacement of the control piston of an upstream control valve from its neutral position in a battery-type arrangement of a plurality of control valves even if a downstream control valve is in its control position, there is further provided an area (33) compensating the effective area of the relief area (9, 9', 16, 17, 18, F26) said compensating area communicating with return pressure at least in the neutral position (N).

Abstract: Method and apparatus for producing liquid iron from Iron oxide, wherein the iron oxide is substantially converted to sponge iron by passing reducing gas through it in a reduction column (1) and is then melted in a melt vessel (5) which is in open communication with the reduction column by heat generated by reaction of oxygen-containing gas and carbonaceous material which reaction provides said reducing gas. To improve control of the process, the oxygen-containing gas and the carbonaceous material are respectively substantially pure oxygen and coal powder which are delivered separately into the melt vessel, and the liquid iron bath (8) in the melt vessel is stirred so as at least partly to be kept in motion. By separate control of the oxygen and coal supplies, e.g. the level and/or direction of delivery, and by control of stirring, it is possible to control the ratio of CO and CO 2  in the reducing gas and also the heat output in the melt vessel.

Abstract: A nozzle (1) is rotated at high speed about its axis by a mechanism (5, 6) and has a passage (3, 10) for directing a consumable welding electrode (4) eccentrically from the center axis of the nozzle toward a groove formed between objects to be welded. A feed mechanism continuously directs the electrode toward the groove through the nozzle. Shielding gas is supplied to the arc welding zone by nozzles 28. A welding current supply arrangement comprises a current receiving plate (9) fixed to the top end of the rotatable nozzle, a stationary brush (11) having on the upper surface thereof a current feed plate (13), a plurality of rods (19) for holding the brush and the current feeding plate stationary, and a plurality of springs (22) for applying pressure onto the contact interface between the brush (11) and the rotating current receiving plate (9). The pressure is such that the nozzle (1) and the current receiving plate (9) can rotate while the brush (11) and the current feed plate (13) remain stationary and at the same time the welding current can flow smoothly from the brush (11) to the receiving plate (9). This arrangement avoids damage to the nozzle rotating mechanism (5, 6) by archeat or spatters and yet leads to only a small loss of welding current.
