Title: Improvements in or relating to a fluidizing process and apparatus for treating comminuted solid materials
IPC: B01J8/26
Filed: 1945-08-23
Abstract: <PICT:0600796/III/1> In a fluidizing process of treating comminuted solid materials cyclically with different gases in different treatment zones, e.g. the catalytic conversion of hydrocarbons and regeneration of the catalyst, unequal fluid-static heads in contiguous zones 5 and 6 cause circulation of the solid which passes upwardly through zone 6, overflows into zone 5 and returns to zone 6 through the space 10.  A difference in fluid-static head of at least 1 lb. per square inch, and preferably at least 3 lbs. per square inch is desirable and is maintained by using different aeration velocities, for example, 0.3 feet per second in the denser zone and 1.5 feet per second in the less dense zone.  Vaporized hydrocarbons admitted through pipe 3 are cracked in the zone 6 and pass out of the apparatus at 14.  The catalyst is regenerated in zone 5, formed by the annular baffle 4, by burning off carbonaceous deposits with oxygen from pipe 7, and its rate of passage out of this zone may be adjusted by a movable deflector 9; excess heat may be absorbed by a cooling coil 5a.  Catalyst carried out of the apparatus may be separated and returned into the top of the vessel or injected with the oxygen.  In a modified form of apparatus (Fig. 2, not shown), the baffle is formed by a vertical partition extending across the vessel, and the catalyst passes downwardly through the cracking zone and upwardly through the regeneration zone.  Steam for stripping the catalyst may be supplied below the point of introduction of the feed oil.  Similar apparatus (Fig. 3, not shown) is used for the carbonisation and gasification of coal &c. (see Group XII).  In the hydroforming of naphthas containing sulphur compounds, the catalyst comprising molybdenum oxide and/or metal on activated alumina is reduced with hydrogen in the regeneration zone; with sulphur-free naphthas steam is used for regeneration.  Other catalytic hydrocarbon conversion processes referred to are dehydrogenation, desulphurisation, isoforming, and aromaticisation.  When the reaction is endothermic, heating means may be provided.  The Specification as open to inspection under Sect. 91 refers also to the hydrogenation of carbon monoxide to synthesise motor fuels and oxygenated organic compounds using an iron catalyst which is regenerated with hydrogen, and to the oxidation of naphthalene to phthalic anhydride in the presence of vanadium oxide which is regenerated with steam.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to methods of manufacturing electric discharge tubes
IPC: F15B13/02
Filed: 1948-08-16
Abstract: 655,778. Cathode materials and processing. PHILIPS ELECTRICAL, Ltd. Aug. 16, 1948, No. 21567. Convention date, Aug. 19, 1947. [Class 39 (i)] In the manufacture of a discharge tube the outgassing and activating of the cathode are performed as two distinct operations. In the graph the pumping time T is plotted against the pressure P. The cathode comprising compounds to be decomposed, for example, carbonates to be converted to oxides, is heated initially at point U instead of point Q. Thus the cathode is outgassed before the activating pressure is reached (dotted line). After the compounds are decomposed there is cessation of cathode heating until the activating pressure is reached at point W. The pressure increment U to V is substantially the same as would be the case, Q to R, if the cathode were not heated until point Q. The saving in pumping time corresponds to distance W-S.

Patent GB-579255-A (GB)
Title: Process for the esterification of wood
IPC: C08H8/00
Filed: 1943-12-31
Abstract: The electrical insulating properties and resistance to moisture of wood are improved by treating the wood with an esterifying mixture containing an organic carboxylic acid, an organic carboxylic anhydride and a polyvalent metal halide under conditions such that the original form and fibrous structure are retained.  The wood may be treated in thin sheets or veneer or in disintegrated condition such as wood meal.  The esterifying mixture appears to react with the lignin and pentosan content of the wood as well as with the cellulose since after the esterification little or no staining is effected when the wood is subjected to the phloroglucinol test.  The esterification may be carried out to an extent corresponding to an increase of the combined acetic acid content of 15-55 per cent by weight of the unacetylated wood.  Sheets of natural wood veneer may be formed into bundles, the individual leaves being separated by a suitable material and supported in a closed vessel through which the esterifying medium is circulated.  Wood meal may be packed into bags or containers before being placed in the esterifying medium. The esterification treatment renders the wood resistant to substantive cotton dyestuffs such as Chloramine Sky Blue.  The moisture regain of air-conditioned material is reduced.  The electrical properties such as dielectric constant and power factor are improved.  The resistance to fungi and bacteria is increased. In examples, small pieces of oak or birch wood veneer are soaked in glacial acetic acid and then treated in a warm bath comprising 90-75 per cent acetic acid, 7-20 per cent acetic anhydride, and 3-5 per cent zinc chloride.  A higher degree of esterification may be effected by subjecting the already esterified wood to a further treatment, using a bath containing a higher proportion of anhydride and using an inert solvent, e.g. benzol as diluent.  The acetylated wood may be used in plastic moulding powders, and laminated plywood boards.  If the esterification is carried out on laminated plywood board or bonded veneer, the resin glue or other bonding material must be chosen to be of such a nature that it is resistant to the esterifying agent.  The process may be applied to resin-moulded wood meal mouldings in the form of moulded sheets or to moulded articles.  Esterified wood veneer may be used in the manufacture of plywood with or without other sheet materials, e.g. cellulose acetate fabric or sheet or esterified paper sheet. Specifications 269,530 and 336,969, [both in Class 2 (ii)], are referred to.

Abstract: <PICT:0358621/III/1> <PICT:0358621/III/2> <PICT:0358621/III/3> <PICT:0358621/III/4> In the manufacture of cement, the slurry, before delivery to the rotary kiln 1, is spread as a coating on bodies such as hanging chains or pieces of corrugated metal 6 which are traversed through a drying-chamber 4 outside the kiln and communicating therewith through a passage 7.  The coating is effected by allowing the chains 6 to dip into a slurry tank 14, Fig. 3, by spraying through a nozzle or by means of discs 20, Fig. 5, or by pressing the plastic slurry on to the chains by means of rollers 41, 42, Fig. 7. The waste gases from the kiln 1 pass through the drying chamber in counter-current to the chains 6 which are suspended from the rotary cover 5.  Disposed adjacent the passage 7 is a rod or roller 17 adapted to flex the chains and release them suddenly, this action, together with the impact against the wall 18 of the slurry tank or the wall of the spraying or pressing chamber, serving to dislodge the dried coating of slurry.  In the modification shown in Fig. 5, the steam evolved in the spraying chamber 25, instead of escaping directly to the flue 13 leading to the chimney 2, is passed through a condenser 27 which encloses vertical pipes through which the slurry is fed upwardly to the spraying discs 20.  In a further construction, the passage 7 connecting the drying chamber with the kiln 1 is replaced by a vertical shaft having perforated walls so that the whole of the gases from the kiln pass through the material which falls into the shaft from the chains 6.  A screw is provided at the base of the shaft to feed the material into the kiln.  Modifications are also described in which a vertical partitioned drying-chamber is employed, the hanging chains 6 being replaced by endless chains which pass from a slurry tank up one side of the partition, over a driving pulley, and down the other side of the partition to an agitating or flexing device which dislodges the dried coating.
