Title: Method of producing acrylonitrile and methacrylonitrile
IPC: B01J27/186
Filed: 1962-06-18
Abstract: Acrylonitrile or methacrylonitrile is produced by reacting propylene or isobutylene, with ammonia and oxygen at 400 DEG  to 520 DEG C. in a solid bed in the presence of a catalyst which contains bismuth phosphomolybdate on a silicic acid support and applying this as a coating to compact crystalline cores of natural or artificial inorganic minerals or mixtures of minerals, having a grain size of 1 to 8 mm. and a maximum porosity of 10%. The catalyst may also contain compounds of beryllium, calcium, strontium, barium, zinc, cadmium, lithium, sodium and/or silver up to an atomic ratio of 30:100 with respect to molybdenum.  The inorganic minerals may be aluminium silicate, corundum, quartz, feldspar, granite, or sintered magnesite. The reaction mixture may be contacted successively with catalysts of increasing thickness of coating on the cores.ALSO:A catalyst for preparing acrylonitrile or methacrylonitrile contains bismuth phosphomolybdate on a silicic acid support, the catalyst being applied as a coating to compact crystalline cores of natural or artificial inorganic minerals or mixtures of minerals, having a grain size of 1-8 mm. and a maximum porosity of 10%.  The catalyst may also contain compounds of beryllium, calcium, strontium, barium, zinc, cadmium, lithium, sodium and/or silver up to an atomic ratio of 30 : 100 with respect to molybdenum.  The crystalline cores may be formed from compactly fired predominantly crystalline aluminium silicate, corundum, quartz, feldspar, granite, or sintered magnesite.  The catalyst is prepared by spraying the crystalline cores at 100-200 DEG C. with a mixture of phosphoric acid and molybdic acid, or phosphododecamolybdic acid, with bismuth nitrate, nitric acid, and silicic acid in sol form and possibly one or more nitrates of the above mentioned metals and then heating the coated cores for several hours at 300-500  DEG C.

Abstract: 1440012 Assembling prefabricated room units C VAN DER LELY NV 16 May 1973 [23 May 1972] 23428/73 Headings E1A and E1S Prefabricated room units or like building sections are assembled, e.g. in a factory, using apparatus comprising a framework into which floor, wall and ceiling panels are lowered in turn in approximately the correct positions, the framework having various movable stops or supports operable to direct the panels into the precise required positions, whereafter the panels are connected together and the room unit thus assembled is conveyed out of the framework. The stops and supports are pivotally mounted and include: stops mounted on posts at the corners of the framework, which are movable by rams to engage corners of floor and ceiling panels and edges of wall panels; side supports in the form of plates movable by rams to engage wall panels: and stops mounted on the side supports or the sides of the framework for engaging partition walls. The room units are assembled resting on rails, on which they are subsequently rolled out of the framework. A travelling overhead crane is used to deliver the panels. The framework has working platforms. Preferably the floor and top panels have horizontal metal beams to which vertical metal beams in the wall panels are welded. Fig. 10 (not shown) shows a plan of a building made up of five side by side room units.

Title: Improvements in or relating to machines for removing and replacing covers on charging holes
IPC: B66C1/66
Filed: 1962-06-19
Abstract: <PICT:0978335/C4-C5/1> <PICT:0978335/C4-C5/2> A charging larry for a coke oven battery has an arm 35 which is both vertically movable and mounted for swinging about a vertical axis, the arm carrying mechanical gripping means 36 operative for gripping and releasing a charging hole cover 31, and control means 34 for swinging the arm 35 from one position to another, for raising and lowering the arm, and for actuating the means 36.  The apparatus operates as follows: starting with the arm 35 in its rest position 35A, Fig. 8, and in its raised position 35R, Fig. 5, and with jaws 94 of gripping device 36 open, Fig. 11-An operator causes pressure fluid to be supplied to a cylinder 151, Fig. 8, to move a piston 152 and hence a member 110, which has raised end portions 112, 113 see Fig. 9, (not shown), leftwards. Rack 118 rotates shaft 141, gears 144, 145, Fig. 5, transmitting the movement to a shell 40 and to the arm 35 which moves over a charging hole 31, the portion 112 maintaining the arm 35 in its raised position through a linkage see Fig. 4, (not shown), extending from a roller 120 to a collar 135 secured by bolts 47 to a housing 39 vertically movable in the shell 40.  Rotation of the arm 35 is arrested by engagement of a flat 150 on sprocket 141 with a smooth portion of member 110 and, as roller 120 moves down ramp 115, the arm 35 is lowered, through the linkage mentioned above, to the position 35L.  This movement relative to a fixed stop 181 releases a rockable member 171 from plates 175, 177, to permit an arm 52 within the arm 35 freedom to adjust itself longitudinally and transversely to allow the gripping device 36 to centre over a cover 30, and engagement of a rack 117 on the member 110 with a pinion 137 rotates shaft 73, Fig. 5, <PICT:0978335/C4-C5/3> through shaft 138, longitudinally extensive coupling sleeve 63, shafts 61, 56, hammer blow clutch 57a, 57b, and chain 71, to cause jaws 94, Fig. 11, to close beneath head 77 of cover 30.  The jaws 94 are pivoted about pins 95 by a cam surface on a ring 101 which is vertically movable by rotation of the shaft 73 due to its screw-threaded engagement with a sleeve 98 fixed to the arm 35, as described in more detail in Specification 978,337.  The cover 30 is rotated through 470 degrees until a flat 140 on the sprocket 137 engages a straight edge of member 110, thus locking the gripping device 36.  The roller 120 now ascends a ramp 116, lifting the arm 35 and attached parts, to position 35R, at which point rack 119 engages pinion 141 further to swing the arm 35 to the position shown in full lines in Fig. 8.  The oven is now charged, a sleeve 27 being lowered for this purpose, and after retraction of the sleeve 27, member 110 is moved to the right in Fig. 8 to reverse the above described sequence of operations. Specifications 978,336 and 978,338 also are referred to.

Title: Winning copper of a high degree of purity from copper sulphide concentrates
Inventor: STEWART LESLIE
IPC: C22B15/00
Filed: 1967-05-22
Abstract: 1,244,301. Extracting copper from matte. L. STEWART. Aug.22, 1968 [May 22, 1967], No.23737/67. Heading C7D. Copper sulphide concentrate is smelted and reacted with a fluid to produce copper by causing streams of the molten concentrate to converge and subjecting the streams to jets of the fluid at the point of convergence. Fig. 3, shows in plan view and Fig. 2, in sectioned elevation apparatus for carrying out the process in which molten sulphide entering through duct 17c is divided into two streams 17d and e by a baffle wall 14. The two streams move down downwardly sloping surfaces 16a and b to meet above orifice 16c where the combined streams are subjected to downwardly directed jets J of fluid, the reacted melt being collected in container 11b provided with slag offtake 20 and product offtake L2. In a continuous process for the treatment of matte Fig. 1 (not shown) copper sulphide concentrate is melted and passed through a succession of apparatus units of the above type for successive refining operations and reduction to copper. The melt is first oxidized with jets of oxygen, air or oxygen-enriched air to remove iron as oxide, then with jets of nitrogen to remove volatile impurity elements or compounds, Bi, Te, Se, As, Sb, Pb, Zn. In the next two units the matte is oxidized, first to produce a small underlying layer of copper which is removed from the main stream and contains copper-soluble impurities, and secondly to form again a double layer, but this time with metallic copper preponderating over copper sulphide, the small sulphide fraction being removed from the main stream with sulphide-soluble impurities. The copper is then oxidized with oxygen jets and finally treated with nitrogen and solid or liquid reducing agents to form refined molten copper. The side-tracked fractions are separately treated to recover their constituents. The invention may also be adapted to recovering copper from scrap brasses and bronzes, the scrap being melted and treated in units of the above type to remove zinc and volatile impurities by jets of nitrogen or to remove Sn, Pb and Zn as oxides by jets of oxygen. The resulting melt is then sulphided and treated as above described for recovery of refined copper.
