Title: Improvements in or relating to chemical reactions employing catalysts
IPC: B01J8/38
Filed: 1957-09-26
Abstract: <PICT:0832425/III/1> Catalyst for use in a fluidized bed reactor is treated by contacting the catalyst with a flame while suspended in a finely-divided state.  The catalyst may be regenerated by the treatment, or it may be fresh catalyst.  Catalyst fluidized in a chamber 14 (Fig. 1) is treated by a flame emanating from a burner 10, air or oxygen being introduced by a pipe 44.  Catalyst passing overhead is recovered by cyclone separators 20 and 24 and either returned to chamber 14 by a pipe 34, or discharged to a drum 36. Catalyst is introduced into the apparatus by a pipe 50 through the cyclone separators.  In another embodiment the catalyst is introduced at a point near the burner.  The catalyst may be silica-alumina, sand, silicon carbide, clay, diatomaceous earth, aluminium silicate, silica, alumina, or aluminium-magnesium silicate, and is used in the reaction of ethylene dichloride and chlorine to obtain tetrachlorethylene.ALSO:Chloro-substituted ethylenes are produced by chlorinating and dehydrochlorinating ethylene dichloride in a fluidized catalyst bed in which the catalyst is sand, silicon carbide, clay, diatomaceous earth, synthetic aluminium silicate, silica, alumina gel or natural aluminiummagnesium silicate which has been contacted with a flame while fluidized.  Degraded catalyst is removed from the beds and replaced with more catalyst which has been activated or regenerated by being maintained in a fluidized state in contact with a flame.  In examples, tetrachloroethylene is obtained using a silicaalumina catalyst.

Title: Improvements in or relating to mechanism for controlling the feed of webs in printing, sheet cutting and similar machines
IPC: B41F13/04
Filed: 1925-12-05
Abstract: 266,823. Victory-Kidder Printing Machine Co., Ltd., and Wilson, H. W. V. Dec. 5, 1925. Feeding, winding, and registering webs. -In web-feeding mechanism for printing, cutting, and like machines, the feed is varied by means of variable mechanism so arranged that the web-feeding mechanism can be automatically accelerated or retarded at regular intervals between the periods of printing, cutting. &c. In the mechanism shown in the Figure, a drag roller 12, loosely mounted on a shaft 14 geared to a printing. cylinder 11 of an " all-size " machine, is provided with a planet pinion 15 which engages a sun wheel 13 on the shaft, and a pinion formed in a loose drum 57. The shaft 56 of the drum is geared to a shaft 49 which is driven by a Geneva device 48, 47, the shaft 45 of the driver 47 being connected by change-speed gearing to the printing-cylinder. The change-speed gearing comprises pinions 28 - - 30 loose on a shaft 24, and meshing with pinions 31 - - 33 on a shaft 35. The pinion 33 runs on the shaft 35 and is formed with a sleeve on which run the pinions 31, 32. Any one of the pinions 28 - - 30 can be coupled to the shaft 24 by means of a sliding key 37 operated by a hand-lever 41. The key is resilient and is formed with a head 38 entering key ways in the shaft and pinions, plates 39 preventing engagement of the head with more than one pinion at a time. In some cases change-speed geating having sliding wheels is employed. The drum 57 and its driving-pinion 55 may be replaced by a single gear wheel having internal and external teeth. The shaft 24 is geared to the printing-cylinder by means of pinions 17, 21 and intermediate pinions 18 which are mounted on a tumbler 20 and can be set to arrest the shaft or to cause the shaft and printing-cylinder to rotate in the same. or opposite direction. When the shaft 24 is arrested, the drag roller is driven at the same speed as the printing-cylinder by means of the gears 13, 15, the drum 57 remaining stationary. When however the shaft 24 is operative, the Geneva device acts intermittently on the drum 57 between the periods of printing and, according to the setting of the tumbler 20, the drag roller is accelerated or retarded and the feed is increased or decreased, variations in the feed being controlled by the change-speed gearing. The web may be re-reeled by means of mechanism driven by the usual friction device or by the web-drag mechanism. When rereeling is not necessary a second web-drag mechanism driven at the same speed as the above-described mechanism may be provided.

The transmitted signals are thus secret, and the intelligence signal is received in receiver 8. Manually-adjustable delay and attenuation networks (not shown) and an automatic regulator responsive to the output of a comparator 4 fed with both S+B signals, are included for efficient separation of the individual signals from the combination. The masking signal may be an intelligence signal in the reverse direction.

Abstract: 1299490 Extruding magnets PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 June 1970 [28 June 1969] 30875/70 Heading B6A [Also in Division H1] The anisotropy of a permanent magnet, extruded from a mixture of powdered magnetic material and binder through a rectangular nozzle outlet 3 which is surrounded by a device which produces an orienting magnetic field, is improved by causing the mixture to flow between a plurality of shear orienting partitions 4 extending across and along the extrusion passage 2 and in planes substantially perpendicular to the direction of the magnetic field and terminate prior to the nozzle outlet. The permanent magnetic material may be alloys or mixtures e.g. manganese, bismuth, but preferably is a hexa-ferrite BaO, 6Fe2 03, in which the barium may partially or completely be replaced by strontium, calcium or lead, and the plate shaped particles are oriented by the shear effects of passage between the partitions 4 to align the easy axis of magnetization thereof, extending perpendicularly to the planes of the particles, with the orienting magnetic field. In the described embodiment, the permanent magnetic material is obtained by grinding the sintered product of barium carbonate or iron oxide. The orientating magnetic field comprises a D.C. magnetic field of 3 to 10 KOe which is applied through the length of the brass nozzle 1 by permanent magnetic devices, or by a device comprising spaced coils 7, soft-magnetic pole shoes 8, and a soft-magnetic frame 9 closing the magnetic circuit around the nozzle 1. The partitions 4 may comprise magnetic, or non- magnetic material e.g. bronze or brass, and in the described embodiment both the spacing between adjacent partitions 4 and the section of the passage 2 of the nozzle 1 in which they are located decreases in the direction of extrusion. The partitions 4 are of progressively decreasing length transversely from the axis of passage 2, and they taper from their centres to knife edges at their rearward, and desirably also at their forward edges. The extruded magnets may comprise synthetic resin or rubber binder which hardens after extrusion, or may be compressed and sintered after extrusion.
