Title: Process for the isomerization of aromatic alkenyl compounds
Inventor: GANDILHON PIERRE
IPC: B01J31/20
Filed: 1969-07-18
Abstract: 1,205,740. Isomerization process. RHONEPOULENC S.A. 18 July, 1969 [19 July, 1968; 19 Feb., 1969], No. 36411/69. Heading C2C. [Also in Division C5] Aromatic alkenyl compounds of the formula below are isomerized by treatment with a catalytic proportion of a compound of ruthenium or osmium. The compounds which may be so isomerized are of the formula in which A denotes a valence bond, an oxygen atom or an -NR<SP>6</SP>- group, R<SP>6</SP> denoting hydrogen or an alkyl group of 1-5 carbon atoms, R<SP>1</SP> and R<SP>2</SP> denote hydrogen or an alkyl group of 1-5 carbon atoms, n is 1-10, X is 1-3 and R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> denote hydrogen or halogen atoms or alkyl, alkoxy, hydroxy or amino groups or radicals of the formula in which R<SP>3</SP> and R<SP>4</SP> denote alkyl groups of 1-5 carbon atoms and R<SP>5</SP> denotes hydrogen or methyl. If two of R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> are groups in adjacent positions, they may be joined to form a divalent radical, e.g. a methylenedioxy group. Many ruthenium or osmium compounds suitable for use as catalysts are specified, and examples are given in which, inter alia, eugenol yields isoeugenol, methyleugenol yields isomethyleugenol, safrole yields isosafrole, o-allylphenol yields o-propenylphenol, allyloxybenzene yields propenyloxybenzene, 4 - phenoxy - 1 - butene yields 1-phenoxy-1-butene and 1-phenoxy - 2 - butene, p - allyloxybromobenzene yields p - propenyloxy - bromobenzene and N - methyl - N - allylaniline yields N - methyl- N-propenylaniline.

Title: Air-atomizing fuel burner
IPC: F23D11/02
Filed: 1973-08-02
Abstract: 1419819 Air atomizing fuel burner W W VELIE 2 Aug 1973 [22 Aug 1972] 36801/73 Heading F4T An air-atomizing fuel burner assembly has an air-atomizing nozzle 14, Fig. 2, receiving liquid fuel via line 46 and primary air under pressure via line 18 to atomize the fuel, and a flame spreader 66 for location in the gaseous or hydroxyl combustion zone of the combustion flame to stabilize and shape the flame. Flame spreader 66 is a disc of stainless steel or ceramics with a planar flame engaging surface located at a distance X from nozzle 14 about equal to the spreader diameter D. The fuel level in open-topped container 64 is maintained so that a thin film of fuel forms over the nozzle head 60 and air aperture 62, the fuel/primary air spray inducing a secondary air inflow between legs 70 supporting a flame conduit 74 acting also as a radition shield. The primary air is supplied to nozzle 14 by a compressor 10, Fig. 1, at a pressure set by a regulator. The pressure and vacuum sides of compressor 10 are connected via restrictions 36, 38 to a reservoir 12, restrition 38 being larger than 36. During a burning cycle the pressurized air forces liquid fuel from reservoir 12 to the nozzle, the fuel flow rate being adjustable by air regulator 22 and by fuel control 48. When the fuel in reservoir 12 reaches level 58 a float 52 closes a switch 54 to energize a solenoid, thereby shutting a normally-open connection from the atmosphere via filter 32 to the suction line 26 of compressor 10 and initiating a reservoir-refill cycle during which the vacuum applied by compressor 10 to reservoir 12 causes fuel flow thereinto from a remote source 16 via filter 44 and non-return valve 42 until the level 56 in reservoir 12 is reached when the float 52 opens valve 24 and a new burning cycle starts. Burning cycles of, for example, 10 minutes may be separated by reservoir refill cycles of 10 seconds, for example.

The required temperature (e.g. 38-55‹F) is preferably maintained by circulating refrigerant (e.g. cold water) through a coolant passage in the roller 16 from a reservoir 30. In the preferred embodiment the web to be coated is fed via feed rollers 13 to a cutting device 14 where it is cut into wrapper sheets, these sheets being forwarded to wind-up 17 past the roller 16 which is moved to apply glue to the leading and trailing edges only of the sheets. Glue is supplied to the surface of the roller by supply tube 20 having an orifice 21 and fed with glue from reservoir 22 by pump 23. Coolant may be circulated through pipe 26 provided in the reservoir 22 to assist in maintaining the temperature at transfer below 60‹F. The supply tube 20 is moved across the surface of the roller 16 to apply glue thereto only to the width of the sheet to be coated. Light source 25 and photo-detector 28 are provided to regulate automatically the width of the roller to be coated. The preferred glue is one having a viscosity at room temperature of 8000-55000 cps. The use of dextrine is mentioned.

Abstract: 1,205,359. Producing neutrons. COMMISSARIAT A L'ENERGIE ATOMIQUE. 23 July, 1969 [8 Aug., 1968], No. 36968/69. Heading G6P. In a fast neutron source, employing the reaction T(d,n)4He, the rate at which the emitting layer is depleted in tritium and enriched in deuterium is reduced, thus increasing the life of the source. The neutron emitting tritiated target is mounted on a passive support, a thin intermediate barrier being interposed between the target and support. The barrier prevents the flow of deuterous from the support to the target and the flow of tritium into the support. In one embodiment, the support is formed of a hydrogenisable metal, so that deuterium passing through the barrier layer is retained. In a second embodiment, the support is formed of a non-hydrogenisable metal and the deuterium which passes through is removed by vacuum extraction or electrolytically.

A stand for supporting supply reels 15 of paper or the like for corrugating, cutting and like machines comprises a pair of spaced support members 1 with recesses 3 in their upper edges to receive the ends of a reel spindle, and a pair of swing arms 10 for engaging the spindle and lifting the reel on to the stand. As shown, the members 1 have horizontal upper faces 5, two pairs of spindle-receiving recesses 3, 4 and sloping end faces 6, with inclined faces 7 between the faces 5 and the recesses 3, 4. Two pairs of arms 10 are also provided. Each pair of arms 10 is fixed to a shaft 8 journalled in the support members 1 and has a hooked end. A worm mechanism or a screw-and-nut mechanism driven by a reversible motor, or an hydraulic jack 13 is connected to a crank 11 on the shaft 8 for raising and lowering the arms 10. In operation, a reel is placed with its spindle 14 against one of the ends 6 and the arms 10 then moved upwardly. As the arms engage the spindle 14, the spindle rolls towards the hooked end. When the position shown on the left is reached, the spindle rolls towards the faces 7. Upon subsequent lowering of the arms 10, the spindle rolls into the recesses 3. The arms may be raised to a slightly higher position than that already mentioned, in which case the spindle may be rolled along the upper faces 5 and into the recesses 4. The spindle 14 may rest against the surface 6 during lifting. The apparatus may also be used for removing partempty rolls from the stand.
