Abstract: 1517014 Processing radioactive waste SOC EUROPEENNE POUR LE TRAITEMENT CHIMIQUE DES COMBUSTIBLES IRRADIES (EUROCHEMIC) 11 Sept 1975 [12 Sept 1974] 37462/75 Heading G6R A process for decontaminating a radioactive organic solution of a phosphoric acid ester which has been used in the extraction of metals comprises separating the organic solvent from the ester by treatment with concentrated phosphoric acid obatained later in the process, decomposing the ester into phosphoric acids and organic compounds, and converting the phosphoric acids containing the impurities into phosphates which are incorporated in a solid matrix. A solution of tributyl phosphate in kerosene may be treated at room temperature with concentrated phosphoric acid in a pulsed column or multi-stage centrifugal extractor. A purified kerosene phase is removed and the ester phase may be heated to 175 C. or more in the presence of steam or a platinum metal as a catalyst, when hydrocarbons and other organic compounds distil off leaving a concentrated phosphoric acid solution.

Title: Improvements in wire drawing drums for wire drawing machines
IPC: B21C1/14
Filed: 1966-08-22
Abstract: 1,113,381. Drawing drum. FASTENER ENGINEERS Inc. 22 Aug., 1966 [17 March, 1966], No. 37553/66. Heading B3P. A wire drawing drum 11 for a wire drawing machine comprises a wire engaging surface 50 and a flange 51 at one end of this surface to engage the wire as it is wound on to the drum to force the turns of the wire axially along the drum to where it is wound off the drum, the engaging surface 50 being in two portions, a cylindrical outlet portion 50<SP>1</SP> and an inlet portion which defines a shallow concave depression. The wire is pulled through a die (13), Fig. 2 (not shown), housed in a draw-box (22) with a lubrication compartment (23). After passing through the die the wire winds on to one end of the coil and winds off the other end as the drum rotates so that the number of turns in the coil remains constant. On leaving the drum the wire passes over an idler roller (37), Fig. 1 (not shown), biased away from the drum 11 by springs (37) or other suitable means, e.g. pneumatic. In the embodiment illustrated in Fig. 3, the inlet portion merges smoothly in a continuous curve with the inclined face 51<SP>1</SP> of the flange 51 and with the outlet portion 50<SP>1</SP>. In a further embodiment, Fig. 4 (not shown), a similar drawing drum has a wire engaging surface (150) with an outlet portion (150<SP>1</SP>), an inlet portion (150<SP>11</SP>) and a flange (151) at the inlet end. The inlet portion merges in a smooth curve with the face (151<SP>1</SP>) of the flange (151) and flares outwards with a uniform conical surface and merges smoothly with the outlet portion. In operation the drawing drum is driven slightly faster than the speed at which the wire is advanced to a subsequent machine, e.g. for further drawing, cutting, straightening &c., and a slack loop (L) is taken up by the idler roll (35). As the amount of slack increases the tension in the wire leaving the drum decreases and the drum slips relative to the coils thereon with a consequential reduction in the amount of wire fed from the drum and hence the slack is reduced. The recessed type of drum of the embodiments enables drawing of larger diameter wire and also wires of high tensile strength, for a given drum size and any set number of turns of wire on the drum than could be drawn using a conventional cylindrical drum.

Title: A process and water cooled lance for the injection of gas into a molten metal bath by top-blowing

Abstract: 1,203,613. Oxygen lances. ARBED, ACIERIES REUNIES DE BURBACH-EICHDUDELANGE S.A. 15 Aug., 1967 [4 Oct., 1966], No. 37561/67. Heading F4B. [Also in Divisions C6-C7] A water cooled oxygen lance for a top blowing process, has a central conduit 1 through which a primary oxygen stream which may contain pulverulent or granular solid material in suspension, is provided, and a concentric outer conduit 2 for the supply of secondary oxygen. The primary oxygen stream which effects the decarburization of the melt is supplied through a long-necked converging-diverging member 11, 12, whilst the secondary oxygen stream, effecting dephosphorization of the melt, is supplied through semihelical channels 3 of semicircular cross-section machined into the outside of the member 12, to form a non-mingling giratory envelope around the primary oxygen stream. Both the angle of inclination of the channels 3, or the area of their cross-section may be varied throughout their length. Replacement of the members 11 or 12 may be effected while the lance is in an operating position, simply by breaking one weld 8, and removing the external reinforcing member 6 to obtain access to the members 11 or 12. Variation of the flow rate of the secondary oxygen stream allows variation of the spread of the gas jet issuing from the lance and so control over the dephosphorization of the melt independently of its decarburization.

Filed: 1928-12-21
Abstract: 317,462. Soc. Anon. des Distilleries des Deux-SÞvres. Aug. 17, 1928, [Convention date]. Acetic acid. - In the process for separating acetic acid from its aqueous solutions by treatment with a solvent and dehydration of the resulting extract of acetic acid, solvent and residual water, as described in Specification 296,974, the dehydrated mixture, of acetic acid and solvent is separated by distilling with an accessory liquid forming with the acetic acid a binary mixture of minimum boiling point. As shown, aqueous acetic acid is treated in a tower 3 with amyl acetate and the resulting extract is distilled with ethyl acetate in a column 6 to remove water, as in the earlier Specification. The anhydrous solution of acetic acid in amyl acetate passes by a pipe 10 to a column 17 charged with a petroleum distillate boiling between 114-116‹ C. Pure amyl acetate issues by a pipe 14; a minimum boiling-point mixture of acetic acid and petroleum is passed to a condenser 12 and is separated into two layers bv the addition of 1 per cent of water. The petroleum is returned to column 17 and the acetic acid passes to a column 15 in which it is freed from small quantities of petroleum and water, and issues in the anhydrous state at the bottom of the column. Other suitable accessory liquids are dimethyl cyclohexanone, toluene, and octane.
