Patent GB-1069828-A (GB)
Title: Polymeric compositions
IPC: C08L9/00
Filed: 1966-05-03
Abstract: The hardening rate of synthetic trans-1,4 polymers of isoprene having at least 85% of the units in the trans-1,4 configuration, or copolymers containing at least 80 mole per cent of such trans-1,4 polymers of isoprene is increased by dispersing therein a minor proportion by weight of a crystalline resin having a softening point above that of the trans-1,4 polymer.  The trans-1,4 polymer may be a polyisoprene or copolymer of isoprene with less than 20 mole per cent of butadiene, piperylene, styrene, ethylene or propylene, and having at least 85% of isoprene units in the 1,4 configuration. The resin may be alban resin, shlllac, trans-1,4-polybutadiene, a butadiene/piperylene copolymer, trans-1,4-polypiperylene 1,2-polybutadiene or isotactic polypropylene.  The compositions may be formed by milling or by mixing in solution to form a concentrate of the resin in a minor proportion of the polyisoprene. In examples, trans-1,4-polyisoprene is mixed with (I-IV) trans-1,4-polybutadiene, (V) a crystalline butadiene/piperylene copolymer, (VI) alban resin, (VII) shellac and (VIII) isotactic polypropylene.

The material may be iron or nickel or an alloy of these two metals. The casing 23 preferably consists of a material such as synthetic resin which forms a thermal insulator to minimize the influence exerted on the temperature of the element 19 by the temperature outside the casing 23.

Abstract: Hydrocarbons and oxygenated derivatives are synthesized from a gas mixture containing hydrogen and carbon monoxide by contacting at elevated temperature and pressure with a fluidized bed of powdered iron catalyst; a molar ration of hydrogen to carbon monoxide of at least 2.5, preferably more than 3 : 1, being maintained during a pre-conditioning period, the process then being continued with a gas mixture having a lower hydrogen to carbon monoxide ratio, preferably about 2 : 1.  The feed gas may contain minor amounts of normally gaseous hydrocarbons, water, and nitrogen, and preferably not more than 2 per cent of carbon dioxide.  It passes upwards through the catalyst bed, products being condensed, and at least part of the uncondensed gases recycled.  In examples, a fused magnetite promoted with potassium carbonate is used at about 650 DEG  F. and a total pressure of 400 pounds per square inch.

Abstract: 1,222,755. Benzene. GULF RESEARCH & DEVELOPMENT CO. 21 April, 1969 [25 April, 1968], No. 20160/69. Heading C5E. Benzene is produced by the following process steps: (a) subjecting a gaseous mixture of hydrogen and an alkyl aromatic to thermal hydrodealkylation at 538-982‹ C. in a primary reaction zone (which as described comprises two reactors in series); (b) separating the primary zone effluent to recover benzene and a mixture comprising unreacted feed, polyphenyls and higher boiling polymeric compounds; (c) adding hydrogen to said recovered mixture, flash vapourizing the mixture to separate as a vapour constituents boiling below 427‹ C., and rejecting liquid higher boiling polymers; and (d) subjecting the vapour from (c) to hydrocracking at 482-816‹ C. in an auxiliary reaction zone, whereby at least part of the polyphenyls present are converted to benzene which is recovered. The recovery of benzene from the primary and auxiliary reaction zones may be effected simultaneously in a single separator. The unreacted alkyl aromatics may be recycled. The effluent from the primary reaction zone may be subjected to mild hydrogenation before separation. The auxiliary reaction may be carried out with or without a catalyst, suitable catalysts being natural clay, alumina, silica-alumina, and sulphided nickel on a suitable support. The feed may contain up to 10 wt. per cent of C 6-12  paraffins. Several feeds are mentioned, but the specific description describes the treatment of toluene with the aid of a detailed flow-sheet.

Title: Apparatus for forming soil pots
IPC: A01G9/10
Filed: 1955-07-12
Abstract: 789,307. Moulding soil pots. WINGERDEN, A. VAN, and HOLLANDER, J. C. DEN. July 12, 1955 [July 12, 1954], No. 20190/55. Class 87(2). A compression moulding machine, especially for making soil pots, comprises a platform 9 for a tray 12 filled with soil, a grid 25, 26, compression plates 28 and socket-forming pegs 30, the platform 9 being movable relatively to the grid 25, 26 and the compression plates 28 being connected to a movable ejector plate 15. The grid 25, 26 is in the form of a frame comprising vertical walls 25 and vertical walls 26 at right angles thereto and intersecting them to form cells 27, the lower edges of the walls being tapered to a sharp edge. The walls 25 depend from the transverse bars 24 of a frame 23, 24 which is fixed by sleeves 22 to vertical corner rods 7. The platform 9 has sleeves 10 at its corners slidable on the rods 7, and has elevating posts 14 for engaging with the ejector plate 15. Each compression plate 28 is vertically movable in a cell 27 and is connected to the plate 15 by rods 29, and each has an opening for the passage of the corresponding peg 30. The pegs 30 depend from the transverse bars 24. On the operation of a stem 43, by a handle 44, a valve 42 is opened to allow hydraulic fluid to be forced by a pump 35 to the bottom of a cylinder 21, so raising the platform 9 until the soil engages the compression plates 28 and the lower edges of the walls 25, 26. The posts 14 are of such a length that they engage the plate 15 after the soil has been compressed, so raising the plates 28 while the walls 25, 26 and pegs 30 penetrate the soil, Fig. 5. The stem 43 is then moved to close the valve 42 and open the valve 41, whereupon the plate 15 descends by reason of the downward movement of the piston in the cylinder 18 and the platform 9 is moved downwards, Fig. 6, leaving the soil compressed into soil pots with sockets for plants or seeds. In a modification the soil, after being divided and compressed, is raised while still in the spaces between the walls 25, 26, Fig. 11, and aluminium foil is then arranged on the tray, whereupon the parts 25, 26, 28 and 30 with the soil pots are again lowered and the foil is pressed downwards to form a lining for the tray. Specification 636,001 is referred to.

Title: Improvements in or relating to process and apparatus for the production of fuel and synthesis gases
IPC: C10J3/46
Filed: 1953-07-21
Abstract: 725,635. Gasifying carbonaceous materials. KOPPERS CO., Inc. July 21, 1953 [Oct. 23, 1952], No. 20265/53. Class 55 (1). Fuel or synthesis gases &c. are produced by introducing 'the reaction products from a "dust gasifier" employing finely divided fuel and oxygen-containing gas into a moving bed of solid fuel and causing them to flow co-currently with the bed before separation of the solid residue from the gases. Fuel for the dust gasifier may comprise lignite, high or low grade coals, high molecular weight hydrocarbon oils, heavy petroleum oils, pitch or tar. A number of dust gasifiers 40 arc located round the top of a secondary gasification chamber 44 containing a bed of solid fuel, e.g. lump coal fed continuously from a hopper 51 and moving down through a grate 48 and feeder 49 to an outlet 42. Each of the gasifiers 40 comprise a fuel dust-oxygen supply pipe 14 and an annular steam nozzle 4 with inner and outer cooling jackets 5, 6. The coal-oxygen proportions are such that part of the coal is burnt to carbon monoxide and at the reaction temperature of 3050‹ F. the rest combines with steam and oxygen to produce carbon monoxide and hydrogen. The hot products at e.g. 2600‹ F. carbonize the lump fuel on the top of the bed and gases produced are led off through an outlet 47. Carbon carried over from the dust gasifiers reacts with carbon dioxide and steam present in the gases; distillates and possibly part of the carbonized fuel also participate in this reaction. The final gas may comprise CO 51.4 and H 2  39.1 per cent. In a modification lump coal is carbonized by contact with hot flue gases in a retort above the secondary gasifier in which a descending body of coke is built up. Hot residue is burnt and the flue gases pass in part to the retort and a part to a pebble heater whence the pebbles flow into a steam superheater which supplies the dust gasifier nozzles. Steam and oxygen may be introduced directly into the secondary gassifier; the residence time of the gases therein may be from 0.2 to 3 seconds.
