Abstract: Sulphophenyl esters can be made amongst other routes by reacting an acyl halide with a phenol sulphonate salt, but it has been suggested in the prior art that there are substantial problems or disadvantages associated with carrying out the reaction in the presence of an organic solvent such as gelation of the reaction medium or excessive reaction times.In the present invention, the process employs as organic solvent high boiling point primarily aliphatic hydrocarbons which forms with linear acyl halide a reaction medium in which products of high and/or improved purity and/or yield are obtainable without gelation and in reasonable reaction periods, especially between C₆-C₁₀ linear acyl chlorides and sodium phenol sulphonate.It has been found advantageous to pre-dry the phenol sulphonate salt by heating it when dispersed in a high boiling aliphatic or aromatic hydrocarbon solvent such that water and solvent are co-removed, with the result that in a subsequent esterification reaction with acyl halide an improvement in yield and/or purity of the sulphophenyl ester can be achieved.

Abstract: The method consists, in its first variant in dissolving a 20-50 mm fraction of crystalline silicon in liquid aluminium at a temperature of 780-820 DEG C while continually mixing the ingredients in a reverberatory furnace until obtaining an alumino-silicon melt and while simultaneously introducing, under the level of the melt, a 0,3-1.0 mm fraction of crystalline silicon with a jet of an inert gas. The second variant of the method consists in the joint dissolving of the mentioned fractions of silicon in the liquid aluminium at a temperature of 780-820 DEG C while continually mixing the ingredients in the reverberatory furnace, the 0.3-1.0 mm fraction of silicon being pressed together with barium chloride and a flux before dissolving.

Abstract: To detect the frequencies from the measured voltages (u,u') of two branches (A,B) to be compared, voltage half-cycles of the same polarity are passed as a square-wave signal (a,a') by computerised branch units (AG,AG'), in serial form, to a computerised central control unit (ZG), for centralised determination of the frequency, and at the same time the voltage amplitudes are determined from the relevant voltage half-cycles (u, u'), are stored and are fed in serial form to the central control unit (ZG), together with adjusting signals from the isolators (TS, TS') in each case during the voltage half- cycles of opposite polarity, as signal telegrams (St, St'), where they are processed into voltage and frequency matching signals which are transmitted back to the branch units (AG, AG') in serial form, the process being repeated until the central control unit (ZG) produces a switching signal once synchronism is reached which, transmitted in serial form, triggers a switching command for the branch (A) in the relevant branch unit (AG). <IMAGE>

IPC: C23G5/00

Abstract: A method and apparatus for removing hydrocarbons which are difficult to vaporise from fine granular material, in particular for cleaning cutting oil containing metal shavings. The material is loaded into a retort by means of a loading device (8) supplied with protective gas and flows through the latter continuously with oxygen being excluded until it reaches an unloading device also supplied with protective gas. In order to eliminate an explosion hazard in this process and to increase the cost efficiency of the method, the material is compacted both in the loading device (8) and in the unloading device in a tube (9) by an intermittently acting ram (13) in the axial direction to form a gas-permeable plug (15) which largely fills the tube (9). After leaving the tube (9) and before the material enters the retort, the plug (15) is again converted into a flowable material flow. Especially dividing up the protective gas flow in the tube ensures both that oxygen cannot enter the retort and too much protective gas cannot escape into the atmosphere. <IMAGE>

Abstract: The system reduces the difference between the response of a roughly rectangular shunt and the voltage waveform applied to it, a difference arising from the skin effect and the proximity effect. The compensation system has an optimized path length for the circuit measuring the potential difference produced in the shunt when a current is flowing. The path in question starts from the centre of the resistive material forming the shunt and progresses towards the outer wall of the said resistive material according to a function which is not monotonic and which may even have loops in it. More particularly, such a shunt has a rectangular geometry which maximizes the dissipation in the surrounding medium of the heat produced by the said shunt. <IMAGE>

Abstract: In preparing alkanesulphonic acids by sulphoxidation of n-paraffins containing between 12 and 18 carbon atoms, using UV radiation to initiate the reaction (light-water process), a mixture is obtained which spontaneously allows a substantial part of the unconverted n-paraffins to separate from a mixture containing the alkanesulphonic acids together with water, sulphuric acid and n-paraffins. 
     The aforesaid mixture is fed with one or more alcohols having four or less than four carbon atoms, preferably isopropanol, to form a two-phase mixture. 
     The two-phase mixture is extracted with supercritical CO 2 , which extracts the n-paraffins, these being recycled to the sulphoxidation process. 
     The paraffin-free product is suitable for preparing alkanesulphonates of the desired type by neutralisation with suitable bases.

Abstract: Apparatus and method for the ultralow temperature processing of metallic, carbide, ceramic and plastic parts and items to materially increase their wear, abrasion, erosion and corrosion resistivity, stabilize their strength characteristics, improve their machinability and provide stress relief. An insulated box-like treatment chamber (10) is disclosed which includes a perforated platform (32) extending parallel to and spaced above the bottom of the chamber (20). Parts and items to be treated are supported on the platform (32) and cryogenic liquid is introduced into the chamber below the platform (32) in accordance with a time-temperature program which reduces the temperature of the parts and items in stages to -195°C (-320°F) by initial cooling of the parts and items by evaporating vapors from the cryogenic liquid pool in the space below the platform and thereafter by partial or substantial submersion of the parts and items in the cryogenic liquid. After a soak period at the -195°C (-320°F) temperature level, the temperature of the parts and items in the treatment chamber is raised to ambient by controlled evaporation of the cryogenic liquid therein. Temperature and liquid level monitoring devices are mounted in the treatment chamber and information derived therefrom is utilized by a process controller to direct the supply of cryogenic liquid to the treatment chamber in accordance with the desired temperature descent and ascent profiles for the weight of the parts within the chamber.
