Shields 12, 13 are of frusto-conical form.
Patent GB-277391-A (GB)
Abstract: 277,391. Johnson, J. Y., (I. C. Farbenindustrie Akt.-Ges.). March 10, 1926. Cleansing-compositions. - Sulphonic acids of aromatic polynuclear hydrocarbons substituted in the nucleus by a hydroaromatic hydrocarbon radicle with at least five carbon atoms, or salts of such sulphonic acids, are added, instead of a soap, to aqueous liquids used in the washing, fulling, or cleaning of, or for removing spots from, fibres or fibrous materials. The sulphonic acids of cyclohexylnaphthalene and of the isomeric methylcyclohexylnaphthalenes for use in the processes, may be obtained as follows:- Cyclo-hexylnaphthalene, obtained by heating together naphthalene and cyclohexanol for five hours at 50‹ C., is treated with sulphuric acid at a low temperature to obtain the sulphonic acid. The sodium salt has a very high wetting power. Methylcyclohexanol, obtained by hydrogenating cresylic acid, is treated with naphthalene and sulphuric acid at 80-90‹ C. to give a mixture of sulphonic acids of the isomeric methylcyclohexylnaphthalenes. The alcohols specified above may be replaced by the corresponding unsaturated hydrocarbons, used in presence of a condensing agent, such as sulphuric acid, or by mixtures of alcohols. The subject-matter of Specification 271,543, [Class 2 (iii), Dyes &c.], is disclaimed.

Abstract: 1,224,922. Improved electrode performance in fused electrolyte fuel cells. BOLT BERANEK & NEWMAN Inc. 11 June, 1968 [9 Oct., 1967], No. 27754/68. Heading HlB. In a fuel cell using a fused electrolyte (i.e. of alkali metal hydroxide) in which peroxide or superoxide is produced by agitation and supply of oxygen to the electrolyte near the cathode, and a hydrogen-permeable but otherwise impermeable anode layer (i.e. of palladium), the current and power density is increased by treating the anode so as to increase the surface area thereof in contact with the fuel and/or electrolyte, and modifying the cathode or operating the cell so as to increase the rate of cathode reaction. In examples, in a cell using a 90/10 fused KOH/ NaOH electrolyte and a palladium anode and a nickel cathode (of four times the anode area), the anode effective surface area is increased by depositing palladium black on the hydrogen surface, or by flaming that surface in air or oxidizing the anode in an air furnace before use, the oxidized surface being reduced in use, and the cathode activity is increased by addition of manganese dioxide to the electrolyte.

[Class 127.] Sugar is extracted from sugar beet cossettes or other subdivided sugar containing material by first subjecting the material to a strong vacuum, for example, wherein the pressure is one-sixth of an atmosphere or less, and thereafter, while maintaining the vacuum, drawing a suitable liquid solvent such as sugar juice from below through the material until the latter is covered, the occluded air and gases being in this manner elimi - nated, and a juice with a minimum of pectose matter being obtained. The process may be carried out with stirring, and while heating to a temperature which need not exceed 50‹ C. The process may be carried out in a vessel 2 provided with a vacuum pipe 8, compressed air supply pipe 8a for introducing air under pressure to discharge the contents when the process is finished, a discharge conduit 9 which may lead to the head of a defusion battery, a heating jacket 11, stirring gear 3, a grid 4 to prevent the cossettes from rising when the solvent is introduced, a charging chute for the cossettes closed by a cover 1, and a conduit 10 for introducing the solvent. Two vessels may be used alternately, the empty one serving as a froth trap for the other, the vessels being connected for this purpose by a pipe 12 furnished with a sight glass 13.

Filed: 1959-08-20
Abstract: A petroleum naphtha is catalytically reformed and the effluent, after separation of a recycle gas, is fractionated to recover a C5 and lighter fraction, a light reformate and a heavy reformate, the light reformate is contacted with an alumino-silicate molecular sieve to adsorb selectively straight chain hydrocarbons and leave a treated light reformate which is blended with the heavy reformate and the C5 and lighter fraction is employed as desorbing agent for the molecular sieve. The petroleum naphtha may boil in the range 50-475 DEG F. and C5 and lighter hydrocarbons may be removed first and combined with the C5-reformate, part being blended with the reformate fuel if desired.  The feed may be purified of sulphur-, oxygen- or nitrogen-containing compounds.  The feed is then reformed at 400-1,000 DEG F. and 25-900 p.s.i.g. in the presence of hydrogen over a platinum, molybdena, chromia or cobalt molybdate catalyst.  The light reformate may have an end point of 250 DEG F. and is treated with a 5  molecular sieve in the liquid or vapour phase at 50-500 DEG F. with a space velocity of 1/4 -20 v./hr./v. and contact time of 2 minutes to 2 hours.  Desorption may be effected at 200-1,000 DEG F., preferably 100-300 DEG F. higher than the adsorption temperature with the desorbing agent in the liquid or vapour phase.  The desorbed hydrocarbons may be used as such as solvents or jet fuel or upgraded by thermal or catalytic cracking or reforming or by isomerisation and blended with the fuel product.

Title: Method and apparatus for processing a natural gas stream
Inventor: SILVA ALFONSO FRANCISCO
IPC: C07C7/12
Filed: 1965-07-06
Abstract: The normal adsorption process for removing water vapour and other condensable fractions from natural gas in which at least 3 adsorbent beds are employed so that at any one time one bed is in use, another is in the initial heating phase of regeneration and the third is in the final cooling phase of regeneration, is modified to allow an increased flow of gas to be treated when necessary by having two beds in use in parallel at the same time while the third is being successively heated and cooled regenerate it.  Apparatus suitable for use in this process comprises separate heating and cooling circuits, the former containing a heater, condenser and separator, and the latter containing means for cooling the hot bed.  In the normal mode of operation, the time occupied by each of the 3 phases is equal, but in the increased flow mode of opeation, the time each of the adsorbing beds are in the adsorbing phase is double the total time taken by the third bed to go through the heating and cooling phases of regeneration. A suitable pneumatic control system for the process is described.

Patent GB-843451-A (GB)
Title: A new acid of the reserpine series, its monoesters and salts thereof, and a process for their manufacture
Filed: 1956-09-24
Abstract: The invention comprises reserpoxidic acid and its mono-esters in which the carboxylic group is esterified with an alkanol, and salts of these compounds.  Reserpoxidic acid is obtained by total alkaline hydrolysis of the alkaloid reserpoxidine (see Specification 824,311) or its salts, and may be esterified with a diazo-alkane.  Partial alkaline hydrolysis of reserpoxidine gives methyl reserpoxidate, but if done in an anhydrous alkanol ester interchange takes place giving a different ester of reserpoxidic acid.  The acid and its esters form salts with acids such as hydrohalic, sulphuric, phosphoric, nitric, isethionic, toluenesulphonic, acetic, tartaric and citric, from which the bases can be regenerated.  Reserpoxidic acid also forms alkali metal salts.  The acid and its esters can be reduced to reserpic acid and its esters which are useful intermediates (see Specification 744,290).  Examples show the hydrolysis of reserpoxidine to methyl reserpoxidate (isolated as nitrate) and reserpoxidic acid, and the esterification of the latter with diazomethane.  The ethyl, propyl and butyl esters are also mentioned.
