Abstract: 905,719. Removing metal by electro-erosion. ATELIERS DES CHARMILLES S.A. Sept. 30, 1959 [Oct. 1, 1958], No. 33179/59. Class 83 (4). In an electro-erosion process there are directed between the workpiece 6 and electrode 10, Fig. 1, solid electrically-conducting particles 19, Fig. 2, of a dimension smaller than the spacing between the workpiece and electrode and in such concentration that they form conducting bridges therebetween. The particles 19 which may be of carbon, a metallic oxide such as silver oxide, a metallic salt or a mixture thereof, are preferably suspended in a carrier liquid which is preferably viscous. This liquid may be a dielectric or an electrolyte: for example an oil, a fatty alcohol such as glycerine or ethylene glycol pure or mixed with water, or a solution of aqueous salts; a wetting agent may also be added. The liquid is drawn from a reservoir 13 by a pump 11 and delivered to a nozzle 15 which sprays it between a disc electrode 10 which may be of hard graphite or metal such as copper, into which the particles become embedded, and the workpiece 6 clamped at 7 to an adjustable table 4. A sump 16 and pipe 17 return the liquid to the reservoir. The liquid may be used to cool the workpiece during erosion. An average potential less than 12 volt is maintained between the electrode and workpiece and a high capacity condenser may be connected therebetween to limit the instantaneous voltage and reduce arcing. In alternative embodiments the particles may be carried by a rod of pasty material applied to the surface of the rotary electrode or the particles may be entrained in a current of air blown into the spark gap; in these cases a separate coolant may be used. The electrode may take the form of a tube or a moving band. A specific example is given of the liquid, voltage, current and speed used for machining a workpiece of cobalt tungsten carbide.

Title: Accelerators for aminoplastic moulding compositions
Inventor: VALE CORWYN PHILIP
IPC: C08K5/46
Filed: 1958-10-17
Abstract: Hot press moulding compositions comprising an aminoplastic resin and an accelerator are characterized in that there is used as an accelerator a cyclic sulphite obtainable by the reaction of thionyl chloride with a compound containing two or more hydroxyl groups.  The aminoplast may be the reaction product of an aldehyde with urea, thiourea, melamine, cyanamide polymers, diaminotriazines, acetoguanamine and benzoguanamine.  Suitable cyclic sulphites can be prepared from ethylene glycol, 1 : 2-propylene glycol, 2 : 3-butylene glycol, erythritol, pentaerythritol, mono-ethers (e.g. the o-cresyl ether) or mono-esters of glycerol, catechol and di-n-butyl tartrate. Suitable fillers are cellulose, regenerated cellulose, cellulose esters or ethers, wood flour, sisal, asbestos, silica, talc, asbestine, china clay, and glass fibres.  Mould lubricants such as zinc stearate may also be added.  In typical Examples (1) an aqueous urea-formaldehyde syrup is mixed with ethylene sulphite and hexamethylene tetramine.  Alpha cellulose is impregnated with the mixture, dried, and ground with zinc stearate to give a moulding powder; (12) melamine and formaldehyde are reacted at 90 DEG C. until a drop gives an opalescence in water.  Glyceryl monocresyl ether is added to the solution at 50 DEG C. and then asbestine and zinc stearate are mixed in.  The product is dried and ground with catechol sulphite.ALSO:Cyclic sulphites, containing the group -O-SO-O- as part of a ring are produced by the reaction of thionyl chloride with compounds containing two or more hydroxyl groups in the molecule. They are useful as accelerators for aminoplasts (see Group IV(a)). In some cases bicyclic products are formed.  In examples thionyl chloride is reacted with ethylene glycol, 1:2-propylene glycol, 2:3-butylene glycol, erythritol, pentaerythritol, mono-ethers (e.g. the o-cresyl ether) or mono-esters of glycerol, catechol, and di-n-butyl tartrate.
