Title: Disproportionation process
Inventor: WILLIAMS KEITH VAUGHAN
IPC: B01J31/12
Filed: 1966-04-07
Abstract: Acyclic olefins are disproportionated in the presence of a catalyst comprising Re2(CO)10 on Al2O3.C3- 30 alkenes e.g. propylene up to octenes are described as suitable feedstocks.  An example describes the disproportionation of propylene to ethylene and n-butene in a fluidized reactor.ALSO:Disproportionation catalysts comprise Re(CO)5 on Al2O3.  The Al2O3 may be pretreated, e.g. with acid, fluidised by an ascending column of inert gas and then subjected to contact with Re(CO)5.  In examples g -Al2O3 of surface area 255 m2/gm and pore size 55  was treated with HCl, washed with distilled water, dried, activated in air at 580 DEG C, then in nitrogen at 580 DEG C and fluidised in contact with Re(CO)5.  The product contained 10% Re(CO)5.

Abstract: 1,088,270. Protective systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 11, 1966 [April 12, 1965], No. 15551/65. Heading H2K. An alternating current sensitive timing device having an inverse time-current characteristic comprises a saturating-core transformer S, a capacitor 16 connected through a rectifier 15 to a secondary winding 13 of the transformer and a relay 18 connected across the primary winding 12 of the transformer, the capacitor C being progressively charged in steps by current flowing in the secondary winding 13 during cyclic reversals of the core saturation so causing the voltage across the primary winding 12 to increase to the actuating voltage of the relay in a time related inversely to the amplitude of the input current. In the overcurrent relay arrangement shown, an excess current causes a relay A to open its contacts A<SP>1</SP> to permit the capacitor 16 to charge. At the end of the timed period, the relay 18 closes its contacts 20 to energize a holding coil 26 and a trip relay B. When the excess current ceases, the relay A releases and closes its contacts A<SP>1</SP> to discharge the capacitor.

The loopers are shifted sidewise by virtue of tilting movements imparted to these rock shafts about the pins 115,149. The endwise and sidewise movements of the loopers are timed so that the loopers describe elliptical fields which are substantially horizontal and at the relatively remote side of the needles.

[Class 40 (iv)] [Also in Group XL] A masking wave is periodically reduced for a brief period to zero or some other definite amplitude as shown in Fig. 3 by means of a circuit 6 supplied with pulses from a source 2, Fig. 7, pulses from the same source are amplitude-modulated by the signal that it is desired to send and the masking wave and the modulated impulses are combined in a circuit 7 in such a way that the modulated impulses occupy the interruptions in the masking wave. The combined wave is then used to modulate a carrier which is received by the circuit shown in Fig. 8. Pulses synchronous with the signal pulses and derived from the combined wave or from some other transmission are used to render a circuit 15 conducting periodically so that appropriate portions of the received carrier are passed on to a demodulator 17 where they are converted to modulated pulses which are converted to speech &c. currents in circuit 18. The masking wave may be noise or speech or scrambled speech or the complex wave from a distributer or carrier multiplex system.

Title: Improvements in or relating to a process and apparatus for neutralizing and drying sulphate of ammonia or other granular or crystalline substances
IPC: C01C1/249
Filed: 1950-06-30
Abstract: <PICT:0668601/III/1> In neutralizing and drying crystalline or granular substances, e.g. ammonium sulphate or sodium sulphate, the substance is freed from most of its moisture, say 1-3 per cent content, in a centrifuge 1 and is sprayed in the centrifuge with a predetermined quantity, e.g. two gallons per four cwt., of water from tank 2 through rose 4 to wash away most of the free acid without dissolving the substance itself.  The crystals are discharged through a hopper into a vertical cylinder 6 and are subjected to the action of a solid or gaseous neutralizing agent, e.g. ammonia entering at 7 or ammonium carbonate or sodium carbonate added through the hopper. The crystals are fed by turntable feeder 8 driven by motor 9 to the bottom of an air elevator 12 and are lifted by gases withdrawn from cylinder 6 by fan 14 heated at 15.  The crystals pass from expansion chamber 16, while gases are withdrawn through metal screen 17, down cataract tower 18 having baffles 19 against a stream of hot air from fan 20 and heater 21.  The dried salt is stored in container 22 before being weighed and bagged at 23.  The air for the elevator and cataract tower may be supplied by the same fan.

Abstract: 102,377. West, P. C. H. Nov. 24, 1915, [Convention date]. Basic lead sulphate is produced by a process of the kind in which galena is volatilized on a bed of coke and oxidized with air, the improvements consisting in maintaining the coke at a comparatively low temperature, for instance 1000--1100‹ C., by aspirating air through the apparatus instead of injecting it under pressure, and effecting the oxidization of the galena in two stages by admitting air to the furnace above the coke and also to a chamber outside the furnace which receives the vapours on their way to cooling and dustseparating apparatus, the second stage of the oxidation being effected at a lower temperature than the first stage and preferably such that the gases glow with an orange-red to orange colour. The temperature of the coke combustion may be also controlled by admitting a neutral gas, such as carbon dioxide (combustion gas), with the air. The apparatus described comprises a closed furnace with a deep layer of coke d, for instance 1.5 metres thick, having an adjustable air inlet y, y<I> below the fire-bars z and a central ore-feed comprising a hopper a, screw conveyer a', hopper b, and spreading-cone c, the hopper b having, if desired, internal hoppers b<1>, b<2>, Fig. 4, with successively smaller apertures, to render the ore-stream central.
