Abstract: 1,044,771. Purifying hydrocarbons. GAS COUNCIL. March 24, 1964 [April 2, 1963], No. 13070/63. Heading C5E. Sulphur compounds are removed from hydrocarbon feedstocks by passing the hydrocarbon in admixture with a hydrogenating gas, either or both of which may contain olefins and/or carbon oxides, over a hydrodesulphurization catalyst to convert sulphur present into hydrogen sulphide; dividing the treated mixture into a recycle stream and a product stream; removing hydrogen sulphide either from the treated mixture before division into two streams, or from the product stream and optionally also from the recycle stream; using the recycle stream to dilute further untreated mixture before passing the untreated mixture over the hydrodesulphurization catalyst and recycling sufficient treated mixture to maintain the reaction temperature in the region of the hydrodesulphurization catalyst at not more than 450‹ C. Hydrocarbons used include light petroleum gases and light distillates containing appreciable amounts of olefin, e.g. 10% by volume. The untreated reaction mixture preferably contains sufficient hydrogen to hydrogenate all the olefins and/or carbon oxides in addition to the sulphur compounds, the volume ratio hydrocarbon : hydrogenating gas preferably being 3 : 1 to 10: 1. The catalyst, e.g. molybdenum supported on alumina promoted by cobalt or nickel, is preferably maintained at 300‹ to 400‹ C. and the process takes place at 5 to 50 atmospheres pressure.

Hydroperoxides of formula in which R 1 , R 2  and R 3  represent alkoxy-substituted or unsubstituted alkyl groups, Y is hydrogen, alkyl, aryl or alkoxy, and X is hydroperoxy, hydrogen, alkyl, aryl or alkoxy, or R 1  and R 2  are connected, possibly through oxygen, to form a cyclic structure, or R 2  and R 3  are connected, possibly through oxygen, to form a cyclic structure, or may be a substituted or unsubstituted aryl group, are prepared by oxidizing a ketone of formula where Z is hydrogen, alkyl, aryl or alkoxy, or may be a substituted or unsubstituted aryl group, by contacting it with a strong base and then oxidizing with molecular oxygen at a temperature not exceeding 10‹ C., the reaction mixture finally being neutralized so that the desired hydroperoxy compound is liberated from the salt-like derivative originally formed. Suitable strong bases include the quaternary ammonium bases and particularly the alkali metal, alkaline earth metal, and aluminium or Group III A  metal alkoxides. The strong base is usually used in excess with respect to the ketone. An aprotic solvent or diluent may be employed in the oxidation stage. The presence of water should be substantially completely avoided, but alcohols, although not aprotic, may be present in proportions not higher than 20 moles per mole of ketone. The alpha-hydroperoxy ketones prepared may be reduced to the corresponding hydroxy-ketones. They may also be converted to ketone peroxides.

Abstract: 1,052,442. Automatic gramophones. NIPPON VICTOR KABUSHIKI KAISHA. Aug. 16, 1963 [Aug. 20, 1962], No. 32536/63. Heading G5R. Elevating means for an automatic pick-up returning device comprises a push-rod resting on an inclined end surface of a lever which is slidable with respect to the turntable and may be driven in response to rotation of the turntable. Referring to Fig. 1 a pick-up arm (not shown) is secured to shaft 26 which also carries a lever 27. As the pick-up arm rotates whilst a record is being played, the end 27<1> of lever 27 engages the end 33<11> of a trip slide 33 and moves the latter in the direction of arrow b. Movement of slide 33 causes rotation of pawl 11 which is frictionally coupled to pawl 12 which in turn engages pawl 14. At the end of a record a projection 6<1> on the turntable spindle engages the part 14<11> of pawl 14 and so causes gear 10 to mesh with a gear 6 on the turntable spindle. Gear 10 carries a cam 16 rotation of which moves lever 20 to the right in the drawing. A support 23<1> is mounted on the end of a pushrod passing through a supporting post 24 and resting on an inclined end 20<111> of lever 20 so that movement of the lever 20 raises the support 23<1> and the pick-up arm. When the pick-up has been raised, further movement of the lever 20 causes a projection 20<11> to engage the end 27<11>, so rotating the pick-up arm. When lever 20 returns to its initial position the pick-up arm is lowered on to a rest (not shown) which may incorporate a switch.

Abstract: 1,228,284. Filters for obtaining samples of clear liquid; filtering and analysing samples. BOEHRINGER MANNHEIM G.m.b.H. 4 Nov., 1969 [6 Nov., 1968], No. 54018/69. Headings B1D and B1X. Samples of clear liquid for analysis are removed from a suspension 15 (Fig. 9) of solid particles by immersing in the suspension a tubular device 14 which has, at the lower end, a filter disc 6 (Fig. 1) rotating on axle 9, the disc being divided by impermeable separating pieces 7 (Fig. 3) into arcuate sectors 8. Clear liquid is drawn from the suspension through the filter disc and from its upper face through pipe 3 by pump 21 and, after analysis in measurement device 19, is returned to the upper face of the disc and the suspension through pipe 2. Thus, each sector of the filter disc has liquid flowing through it alternately from both sides whereby the pores are automatically maintained free from blockage by solid material. The suspension may be stirred. The disc may be made of weldable sintered metal, or of porcelain. A thermostat 17 is included in the circulation system. If the clear liquid is withdrawn from a crystal slurry, thermostat 17 is maintained at a temperature somewhat higher than suspension 15 and the clear liquid is warmed by coil 20 before it is returned to disc 6 and slurry 15. The liquid may be analysed by measurement of optical rotation, circular dichroism, conductivity, pH value, refractive index, colorimetric investigations (visible, ultra-violet, or infra-red), nuclear magnetic resonance spectroscopy, or polarography. The apparatus has proved useful in the racemate separation of a chloramphenicol intermediate product.

Abstract: 1,232,031. Melamine derivatives. H. H. J. DEUZEMAN. 25 June, 1968 [5 Oct., 1967], No. 30263/68. Heading C2C. [Also in Division C3] A water-soluble methylated methylolmelamine which appears to comprise mainly trimethoxymethyl melamine is prepared by reaction of melamine with formaldehyde and methanol (M : F molar ratio 1 : 3-6) in the presence of sulphamic or N-methyl-sulphanilic or 2-naphthalene-sulphonic acid or N/10 HCl sufficient to maintain the pH acid but not less than 5.9. The reaction is preferably conducted below 140 F. until the free formaldehyde falls below 16 wt. per cent of the reaction mass.

Abstract: 1,252,115. Venting I. C. engine crank-cases. FORD MOTOR CO. Ltd. April 9, 1970, No. 16872/70. Heading F1B. An oil separator 1 in a pipe connecting the crankcase to the air induction system has a tubular inlet 3 divided by a member 7 into a gas passage 9 and an oil return passage 11. The member 7 extends upwardly into the separator chamber 5 and downwardly into the pipe from the crank-case. The baffle 17 has a hole 19 for the passage of oil to the passage 11.
