Abstract: 1,221,879. Extrusion. ALLMANNA SVENSKA ELEKTRISKA A.B. 25 June, 1968 [26 June, 1967], No. 30256/68. Heading B3P. [Also in Division B5] In a method of producing a rod, wire or tube by hydrostatic extrusion of a compacted powder billet, preferably of density at least 60% of that for the solid, the billet is covered during extrusion with a temporary, liquid-tight barrier of non-metallic, yielding material to prevent the pressure medium from penetrating the billet, the barrier being removed after extrusion. The barrier suitably consists of a plastics material having a hardness of at least 60 Shore A, plasticized polyvinyl chloride being preferred. The powder may be metal, metal oxide, metal and metal oxide mixture or a metal coated with a metal oxide. The barrier may be applied by bringing the heated billet into contact with powder or grains of the plastic and further heattreating it, by dipping or by spraying with the plastic or a solution thereof. The extrusion is preferably carried out in an apparatus comprising a pressure chamber 1, formed by a steel cylinder 2 prestressed by means of a wire or tape sheath 3. The billet 31 is extruded through a die 4, held in a die holder 12, into a counterpressure chamber 13. The plessure in the counter-pressure chamber is maintained constant by means of a piston 21 in a cylinder 22 and valve means 27 held in an orifice 26 by means of an adjustable spring 28.

Abstract: 1,064,272. Films. BRITISH CELLOPHANE Ltd. July 31, 1964 [Aug. 1, 1963], No. 30636/63. Heading B5B. A film of a molten thermoplastic material which emits volatile products at melt extrusion temperatures is extruded on to a rotating polished, chilled roller and at least a substantial proportion of the vapours emitted by the molten thermoplastic material are removed from the vicinity of the roller by suction. Suitably the mixture of air and vapours formed in the converging space between the film and the roller is removed by suction at a rate of at least 10 cu. ft. per minute per inch of film width. The film may be extruded at a rate of 70-180 feet per minute. Specified film materials include polyethylene, polypropylene and nylon. In apparatus as shown, film 2 is extruded from extrusion head 1 on to the surface of a highly polished rotatable hollow roller 3 which is chilled by a cooling fluid circulated through the roller by pipes 4, 5. The film 2 is thus rapidly cooled below the melting point to form a solid film which is drawn from the rollers over a guide roller 7 to take-up means (not shown). A suction box 8 extends over the entire width of the film and is connected to suction means via pipe 9, so that substantially all the vapours emitted from the film 2 or from the orifice of the head 1 are drawn away from the converging space formed between the film 2 and roller surface 3 and are thus prevented from condensing on the surface of roller 3.

Title: Recovery of polycarboxylic acid anhydrides
Inventor: LANDAU RALPH
IPC: C07C51/47
Filed: 1952-12-09
Abstract: Maleic and phthalic anhydrides are recovered from a gaseous mixture containing them by passing the mixture in contact with dibutyl phthalate at a minimum of 40 DEG  C. for simultaneous absorption of the anhydrides, and thereafter stripping the absorbed anhydrides from the solution.  The absorption may be effected under conditions such that the resultant solution contains both the anhydrides, which can then be separated by fractionation, or the absorption may be accompanied by simultaneous stripping of the maleic anhydride by passing a countercurrent of an inert gas through the solvent.  For details of operation (see Group III).  U.S.A. Specification 2,574,644 is referred to.ALSO:<PICT:0727828/III/1> Maleic and phthalic anhydrides are separated from a gaseous mixture containing them by passing said mixture into dibutyl phthalate solvent at least 40 DEG C. for simultaneous absorption of both anhydrides, and thereafter stripping the absorbed anhydrides from the solution.  The absorption may be effected so that the solution contains both the anhydrides, the stripping then producing a mixture of maleic and phthalic anhydrides which may then be fractionated; or the absorption may be accompanied by simultaneous stripping of the maleic anhydride (e.g. by employing a counter-current of an inert gas), leaving phthalic anhydride to be stripped from a solvent substantially free of maleic anhydride. Flow-sheets for the alternative methods above are provided.  In Fig. 2, for operation of the latter method, reaction gases are fed into an absorber-stripper 26, down which dibutyl phthalate is passed.  Inert gases from the base of the stripper strip maleic anhydride from the solvent, and the remaining substantially maleic anhydride-free solution of phthalic anhydride in dibutyl phthalate is introduced into a stripper 29 to strip the anhydride from the solvent, which is recycled.  U.S.A. Specification 2,574,644 is referred to.

Title: Electrochemical hole boring machine
Inventor: DICKSON ERIC WINSTON
IPC: B23H3/00
Filed: 1961-08-30
Abstract: <PICT:1029233/C6-C7/1> An electrochemical hole boring machine has a plurality of tube electrodes 11 which are carried by a tool holder assembly 7 (Fig. 1. not shown) towards workpieces 10 or a single workpiece to bore a plurality of holes simultaneously, electrolyte being supplied through the electrodes to the electrode-work gaps. The electrodes are advanced by a screw 5 (Fig. 1.) engaging a nut in the tool carrier and a driving mechanism 16 (Fig. 1.) may be provided for rotating the workpieces 10 or a platen 9 (Fig. 1.) carrying them. There may be provision for a faster approach and return while not boring.  Each electrode is mounted such that it can retract on coming into physical contact with a workpiece so that, should the cutting action of an electrode fail for any reason, the advance and cutting action of the remaining electrodes need not be discontinued.  Fig. 2. shows an electrode 11 comprising a metal tube 21 insulated at 22 to reduce side cutting.  It is mounted in a metal plunger 23 which slides in a metal sleeve 24 and over a piston 25 of insulating material.  Electrolyte which is supplied through a capillary bore 26 in the piston 25 pushes the plunger 23 forward and flows through the electrode to the work 10.  In the event of an electrode touching the work as the tool holder advances the plunger 23 is pushed back in the sleeve 24.  The capillary bore serves as a pressure impedance so that change in back pressure as the electrode advances into the work is smaller than the pressure drop across the impedance.  The electrolyte in the bore serves as a high electrical resistance.  Electrolyte leaking between the piston 25 and plunger 23 is drained away through vents 32 and drain holes 33.  As illustrated in Fig. 4. (not shown), electrolyte flowing from the electrodes is caught in a tray 2 and then passes through a settling tank 50, strainer 51, pump 52, filter 53, valve 54, flow meter 55, filters 31, capillary tubes 26 and returns to the electrodes 11.  There is a pressure gauge at 57 and relief valve 56.  Current is fed to each electrode through wires 34, Fig. 2., in the tool holder, a pick-up ring 35, a metal bush 27 and the metal sleeve 24 and plunger 23.  An overload trip or fuse 40 (Fig. 3. not shown) is included in the circuit to each electrode and a lamp indicates when electrolysing current is passing. When drilling a hole right through a workpiece, in order to prevent escape of electrolyte as the electrode tip breaks through the lower part, a metallic packing piece, a cavity filled with electrolyte or an easily deformable solid may be positioned behind or below the work.  The electrodes may be of surface insulated stainless steel and the electrolyte may consist of 200 gs/l NaCl in H2O. Any electrode position in a tool not required for a particular boring operation may be sealed or capped off.  The electrodes form the subject of Specification 1,029,234.

Abstract: 245,092. Coehrane Corporation, (Assignees of Rode, S. Dahl-). Dec. 23, 1924, [Convention date]. Double silicates.-A base exchanging substance is produced by treating blast-furnace or other slag containing an alkaline earth aluminium silicate, with a strong caustic soda solution. The slag may be granulated by treatment with water and then ground in a ball mill, the ground product being delivered from a hopper 1 into a chamber T having an agitator 2. Alkali hydrate or carbonate solution is admitted at 4, heating being continued until the mixture is dry, the product being pieces about the size of hazel-nuts and smaller. The product is preferably further treated to recover a portion of the alkali and obtain a refined product. For this purpose it is delivered to a hopper 6 from which it passes to a sifter 7. The fine material, passing through a 40-mesh screen, is delivered to a vessel 9 and returned to the vessel T by a hopper 10. The large pieces, retained by a 20-mesh screen, are passed to a hopper 12 and thence to a crusher 13 from which they are returned to the hopper 6. The granules retained by the 40-mesh but passing the 20-mesh screen are delivered to a vessel 8 from which they pass to a leaching vessel 16 in which they are treated with hot water from a tank 20, the solution being discharged to a store tank 17 from which it is passed to the vessel T for mixing with the next charge. The granular material is then further washed with hot water, then with a weak solution of an inorganic or organic acid such as sulphuric or acetic acid for removing remaining free alkali and alkaline earth compounds, then with water, and then with alkali chloride solution to replace the remaining calcium in the double silicate with alkali. The product is then discharged into a draining box 23. The various washing-liquors are supplied in succession from the tank 20 and pump 21.
