Abstract: 775,031. Rolling-machines. SANDVIKENS JERNVERKS AKTIEBOLAG. Sept. 1, 1954 [Sept. 7, 1953], No. 25430/54. Class 87(2). [Also in Group XXII] In a method of rolling sheet or strip material the rolls are continuously regulated so that any change in separating force, caused by changes in the material are balanced by impulses given to the rolls equal to the separating force multiplied by a factor which is slightly greater than the reciprocal of the mill constant. Rolls 14, 15, Fig. 1, adjustable by screw-downs 11 have servo-controlled hydraulic cylinders 12 interposed between the screwdowns 11 and the bearings 16. The position of the rolls 14 relative to the screwdowns 11 is indicated by a pointer 21 pivoted at 20 to an arm 19 attached to the screwdown. The pointer actuates a device 22 controlling a servo mechanism regulating the pressure in the cylinder 12 and over-compensation is applied by inserting bellows 23 between the arm 19 and the device 22 and connected to the cylinder. 12 so that a change in hydraulic pressure moves the reference point of the device. Adjustment of the bellows 23 provides the required compensating factor. In a modification the devices 22, 23 may be incorporated in a device 24 which measures the distance between the roll centres. In another modification an additional device for measuring the thickness of the issuing strip may be incorporated to feed signals into the servo mechanism so that compensation may be applied for any change in thickness resulting from a change in the mill constant.

Title: Manufacture of copolymers containing carboxyl groups
Inventor: BIER GERHARD
IPC: C08F214/06
Filed: 1952-10-10
Abstract: Monomer mixtures containing vinyl chloride as the principal constituent and also containing 0.1 to 5 per cent of an a ,b -unsaturated carboxylic acid are polymerized in aqueous emulsion at a pH of 4 or less in the presence of a nonionic emulsifier, e.g. the reaction products of fatty alcohols with ethylene oxide or mono-fatty acid esters of triethanolamine, or a salt of an aliphatic or aromatic sulphonic acid, e.g. sodium alkyl sulphonate, the alkyl group containing 10 to 18 carbon atoms. Specified comonomers are vinyl acetate and maleic acid dibutyl ester.  Suitable acids are maleic acid or anhydride, fumaric, acrylic, methacrylic, crotonic and citraconic acids.  Catalysts, e.g. a hydrogen peroxide-sodium formaldehyde sulphoxylate redox system, may be used.  The monomers, emulsifier and catalyst (or one component of a redox system) may be added pari passu with the polymerization, the concentration of monomers preferably being not much above the saturation concentration of the aqueous phase. Emulsifier-free polymers may be obtained by using as little emulsifier as possible and (a) precipitating from dilute dispersions, (b) using precipitants which do not diminish the solubility of the emulsifier by forming sparingly soluble salts, (c) forming easily filterable and washable precipitates by transient heating of the dispersions, or (d) washing the precipitate with water, methanol or ethanol.  Suitable precipitants are the chlorides of sodium, potassium, calcium and magnesium and the sulphates of magnesium and aluminium.  Low molecular weight polymers may be removed by washing with methanol, and the product used in lacquers, coatings and adhesives.  In examples toluene-acetone solutions of the polymers are sprayed on aluminium foils and, after drying, the foils are bonded by pressing at 120 DEG  C.  Specification 715,240 is referred to.

Title: Improved process for separating uranium
IPC: C25C1/22
Filed: 1945-10-03
Abstract: 794,490. Electrolysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 3, 1945 [Sept. 14, 1944], No. 25764/56. Class 41. A process for separating uranium from a uranium-containing solution, e.g. an oxalic acid solution, containing a dissolved metallic impurity, e.g. Fe, Cu, Ni, or Cr, comprises admitting the solution to the anode chamber 30 of a mercury cathode electrolytic cell which is separated by an ion-permeable barrier 28, e.g. a ceramic, e.g. alundum, from a cathode chamber 31 containing an acidic solution, e.g. hydrochloric acid, the barrier 28 preventing passage of liquid between the chambers 30; 31 and electrolysing the oxalic acid whereby uranium ions pass to the acidic solution, for subsequent removal and the metal of the impurity is deposited in the cathode mercury 62. The cell comprises two insulating casings 11, 12 bolted together at 22 along co-operating peripheral flanges 16, 20, the floor 17 of the casing 12 having lateral slots 17a to receive cathode discs 46, e.g. of nickel, mounted on a shaft 41 which is rotated by a motor through a shaft 52 and bevel gearing 51, 47. The lower portions of the discs 46 dip in the mercury 62 and the upper portions are immersed in the HCl solution in the chambers 31. Anodes 38, e.g. of graphite, platinum or platinum-iridium alloy connected to bus-bars 32 dip in each chamber 30. The anode and cathode chambers 30, 31 are arranged in groups which are connected in parallel for liquid flow, the liquid passing in series through each group, the chambers of each group being interconnected externally of the casing 12 by U-tubes 103, 106. The oxalic acid solution is delivered by pipes 101 to the chambers 30 and leaves at 102, e.g. at a rate of 150 c.c. per minute, and the HCl solution is delivered by pipes 104, e.g. at 15 c.c. per minute, leaving at 105 enriched in uranium ions. A mixture of nitrogen and chlorine, or chlorine alone, is passed continuously through the apparatus, entering through pipes 110 and 111, Fig. 3, which run inside the walls 18 of the casing 12, each pipe 110, 111 communicating by ducts in the walls 18 with the anode chambers 30. The gas agitates the oxalic acid solution and the chlorine reduces it to CO 2  and HCI, a process which is assisted by anodic oxidation, the CO 2 , most of the nitrogen and some of the chlorine leaving the cell by an outlet in the top of a casing (not shown) surrounding the cell. Mercury is passed continuously through the casing 11 from a pipe 116 to a pipe 117. In one operation of the apparatus, in which the anode and cathode solutions flowed at 50 and at 5 c.c. per minute respectively, a voltage of 4 gave a current density of 0.2 amp. per sq. cm. of cathode and the temperature of the electrolyte rose to 70-75‹ C. The positive terminal 36 is secured to a strap 34 which bridges the ends of the busbars 32 and a plate 63 forms the cathode terminal.

Title: Multi-pass system for source code translation
IPC: G06F9/45
Filed: 1972-06-02
Abstract: 1393295 Programme translator BURROUGHS CORP 2 June 1972 [16 June 1971] 25845/72 Heading G4A In a system for translating a program from a first source language code, e.g. RPG to a second source language code, e.g. COBOL, the translation is effected during sequentially occurring passes of the first source program. As described a first pass checks the syntax of the RPG program to ascertain that it contains no errors that might be translated into the COBOL source program. This is effected by analysing each source program card. If a card is unidentified or contains a comment, a comment statement is written into a desk file and the next card examined. If the card contains a specific card type identification its data fields are analysed and stored in an appropriate table, a syntax and cross-reference of the data being performed. The source card is printed if there is no error. The second pass reads intermediate files and generates COBOL code for storage on intermediate disc files. Tables for later passes are also prepared. During the third pass executable instructions in COBOL code are generated from some of the RPG source and during the last pass the COBOL source language routines are generated by reading all the entries on the intermediate file created during the second pass. The system includes a central process and memory modules together with peripheral devices such as disc files, a card reader and a magnetic tape unit. During the passes the COBOL source file is created on the disc file and subsequently read to the magnetic tape unit.  A test program in RPG is given.
