Paper bags, making. - In completing the bottoms of paper bags by folding and pressing two oppositely disposed flaps on the bag bottom into position against the web of the bag, the bag is tensioned on the peripheries of two spaced rotating discs and one flap is folded by means operating parallel to the path of rotation of the peripheries of the discs and upon the inner face of the web and is pressed into place during contmued rotation, the same operations being repeated on the second flap. Bag tubes, with their bottoms partiallv folded as shown in Fig. 8, are fed by tapes l<1> engaging their side edges around a roller K<2>, Fig. 2, having a notch k adapted to co-operate with a creasing blade K to turn up the flap C<2> about the line C<4>, past a roller K<3> and creasing blade K<1> which turn up the final flap C<3> about the line C<5>, to two spaced discs M around each of which a tape l<1> passes, and the bags are held to the tapes by outer tapes l and are thereby stretched across between the discs. Between the discs two pairs of folding and pressing arms M', M<2> are mounted on hub members M<9> on the shaft M<6> of the discs. To each hub member M<9>, Fig. 3, a disc M<5> is adjustably secured and the disc carries, on an extension M<5a>, a lever M<3 >provided with the folding arm M<1>,< >or M<2>. A roller m<3> on the other arm of the lever controls its movement by riding along the surface of one or other of two fixed cams M<12>, M<13> secured to the framing machine. A pivoted arm M<4> on the disc M<5> carries a roller m' adapted to run in a groove on the face of one or other of the fixed cams to move the arm M<1> or M<2> concentrically with the shaft M<6>. In operation, as the lower left hand arm M<1>, Fig. 2, approaches the rear flap C<2>, the roller m<1> thrusts it forwards to turn down the flap and then the roller m<3> causes it to press the flap against the web of the bag. The adjacent arm M<2> then turns down the flap C<3>, the first arm M' is withdrawn, and finally the second arm M<2> presses the flap C<3> against the bag.

Title: Method of separating plutonium
IPC: C01G56/00
Filed: 1945-07-31
Abstract: Plutonium is separated from uranium by passing a vaporous mixture of the hexafluorides of these metals over a copper surface heated to 100-450 DEG  C., to cause reaction of the copper preferentially with the plutonium hexafluoride and deposition of the plutonium on the copper surface.  The plutonium may be recovered from the surface by washing with a suitable solvent.  In examples, uranium tetrafluoride containing plutonium tetrafluoride, obtained by reacting neutron-irradiated uranium with hydroged fluoride, is heated in the presence of fluorine and the hexafluoride vapours formed are passed through a heated copper tube.  Plutonium is deposited as lower fluoride and uranium hexafluoride is collected in a liquid nitrogen cooled trap.

Title: Process and apparatus for separation of gaseous components from gaseous mixtures
IPC: B01D53/18
Filed: 1954-07-06
Abstract: <PICT:0782901/IV (a)/1> Mono - acetylene is removed from a gaseous mixture by contacting it in an absorbing zone with a watermiscible solvent having selective dissolving power for acetylene, removing the acetylene - enriched solvent from the absorbing zone and passing it through a desorbing zone in countercurrent to a stream of gases stripped from the solvent in a subsequent stripping zone of the process, removing a stream of substantially pure mono-acetylene from the desorbing zone, separately removing partially desorbed solvent containing high acetylenes and the remainder of the dissolved mono-acetylene from the desorbing zone and stripping the partially desorbed solvent by reducing the pressure on the solvent in the stripping zone in at least two successive stages operating at successively lower pressures for the liberation of the remainder of dissolved mono-acetylene, returning dissolved gases liberated in the second or later stripping stage to the immediately preceding stripping stage, and returning dissolved gases liberated in the first stripping stages to the desorbing zone as the said countercurrent stream of gases.  In an example, a fresh cracked gas containing 8.5 per cent of acetylene is mixed with recycle gas from conduit 13 and is fed through compressors 11 and 12 and is then absorbed in a water-soluble organic solvent such as butyrolactone, alphapyrrolidone, dimethyl formamide or glutarimide in absorber 15. Waste gases leave through conduit 19. The solvent then passes to desorber 20 at a lower pressure, in which most of the acetylene is liberated and withdrawn via pipe 21.  The solvent is withdrawn via pipe 23 and passes into a flash tower 22 which consists of three sections 29, 30 and 31 joined by conduits 32 and 33.  When the solvent passes from chamber 29 to chamber 30 additional acetylene is liberated and is passed back to the desorber by line 28.  Live steam is provided through a conduit 40 to a steam jet ejector pump 39 which removes acetylene and other uncondensed material from receiver 36 through conduit 41. Solvent containing the higher unwanted acetylenes pass via pipe 53 to a stripper 54 from which the overhead product passes to a barometric condenser 64 in which the steam is condensed. Specification 702,876 is referred to.
Patent GB-698711-A (GB)
Title: Manufacture of new nitroquinolines
IPC: C07D215/30
Filed: 1951-08-21
Abstract: The invention comprises 6-nitroquinolines of the formula <FORM:0698711/IV (b)/1> where R and R1 may be hydrogen or a methyl group and R1 and R2 may be hydrogen or a halogen atom and esters and complex metal salts thereof.  They are prepared by reacting a nitraniline of the formula <FORM:0698711/IV (b)/2> where R3 is a free or etherified hydroxyl group or a sulpho group, with glycerine, acrolein crotonaldehyde, paraldehyde, formyl acetone or acetylacetone to form quinolines, which may contain methyl groups as substituents in the 2 and 4 positions, when necessary converting the group R3 into a free hydroxyl group and if desired halogenating, esterifying or converting into a complex metal salt the 6-nitro-8-hydroxyquinoline so produced. When the group R3 is an etherified hydroxyl group it is convertible to free hydroxyl by treatment with a hydrogen halide such as hydrogen bromide.  A sulphonic acid group in the 8- position is similarly convertible by hydrolysis.  Metal complexes are obtained by reacting metal salts with the 6-nitro-8-hydroxyquinolines or with their metal phenolates.  In examples (1) 4-nitro-2-hydroxy aniline is heated with glycerine in the presence of arsenic acid and sulphuric acid to give 6-nitro - 8 - hydroxyquinoline I; (2) 6 - nitro - 8-methoxy-quinoline is heated with aqueous hydrogen bromide to give I; (3) I is esterified with acetic anhydride and sodium acetate to give the 8-acetoxy compound; (4) I is chlorinated in glacial acetic acid to give the 5- or 7-chloro-derivative; (5) 4-nitro-2-hydroxyaniline is reacted with paraldehyde and concentrated hydrochloric acid giving 6-nitro-5 (or 7)-chloro-8 - hydroxy - 2 - methyl - quinoline; (6) I is treated with aqueous copper sulphate to give the copper complex and (7) I is esterified with undecylenic acid chloride to give the corresponding 8-undecenoyl compound.

Abstract: 1,274,001. Joining panels; stud and socket fastenings. F. C. DUPRE. 18 April, 1969, No. 19852/69. Headings E1W and E2B. A structure is formed by joining together a pair of elements, such as panels, each having a connector wall member b or b formed with elongated slots as 15 or 16 by abutting the wall members with their slots in register, passing the heads 19 of studs on a locking slide 17 movable along one of the elements through registered pairs of slots, and moving the slide to move the studs along the slots into locking engagement, when each of the studs cannot be withdrawn from its registered pair of slots in a direction along the stud axis. As shown two panels A, B are connected edge-to-edge by means of the flanges b, b' of angle members C, D secured to the panels and the panels are locked together by wedging action between the margins 19a of the stud heads and ramps 20 on the free face of the flange b' around the slots 16. The slide 17 is located by lugs 27 and channels e in projections 26 inclined to the slide which bears tongues 28 arranged to engage the projections 26 in the released position of the slide and cam it outwardly to withdraw the studs from the slots. The latching movement may be effected by tightening the nut 21 on the thread 22 carried by the slide against the fork 24 on the angle member C, while release of the members is effected by unscrewing the nut and imparting a blow to the threaded end of the slide. As an alternative (Fig. 8 not shown) the slide and the member C carry racks engageable by a removable pinion which effects reciprocation of the slide. In place of the angle members C, D triangular tubes may be used (Fig. 13 not shown), or the flanges b, b' may be integral with the panels. In other variations the angle members are of acute or_ obtuse angle for joining panels with their major faces inclined to each other. In a further arrangement (Fig. 14 not shown) the connectors are rectangular tubes which are secured to and join coplanar facing panels, two such sets of joined panels being spaced apart to form a hollow wall which is filled with a foam or cellulose material. A thin sheet material may be inserted being the slotted faces of the connectors (see Figs. 13, 14).
