Title: Ester synthesis
IPC: C07C67/36
Filed: 1959-03-18
Abstract: Esters having 2n+2 carbon atoms in the molecule are produced by a process comprising reacting under the conditions of an oxo synthesis an olefinic compound having n carbon atoms with hydrogen and carbon monoxide in the presence of an oxo catalyst and a stannous compound. Preferably the stannous ion is present in an amount of 0,03 to 3% by weight based on the olefine present. The crude aldehyde-containing product obtained as the result of the oxo process may be fractionated to give the desired ester product or, alternatively, the crude mixture may be decobalted and hydrogenated and then fractionated, preferably under reduced pressure, to separate the desired ester from the monomer oxo alcohol (n+1 carbon atoms) and the dimer alcohol product (2n+2 carbon atoms).  Suitable stannous compounds are, for example, stannous bromide, chloride, citrate, hydroxide, iodide, oxalate, oxide, tannate, oleate, stearate, naphthenate, tartrate, acetyl acetonate and acetate.  In the examples a C7 olefine, propylene and decene-1 yield a C16 ester, a C8 ester and a C22 ester respectively.  In addition some of the "monomer" and "dimer" alcohols are obtained.

Abstract: 917,442. Swash-plate pumps. PITT, A., and BUDZICH, T. March 14, 1961 [March 21, 1960], No. 9383/61. Class 102(1). A swash-plate pump having a ring shaped cylinder block 25, has an annular gallery 26 extending from a peripheral surface of the block 25 thereinto and intersecting each cylinder bore 27 into two axially spaced portions 27a, 27b. A hollow piston 28 extends between each pair of bore portions 27a, 27b and a sleeve 40 defines with the cylinder block 25 a closed annular space whereby leakage of fluid past the pistons from the working cylinder 27b fills the space with pressurised fluid tc reduce further leakage and lubricate the pistons in the bores.27a. Fluid leaking from the latter bore is scavenged through an outlet 2C in the pump body 10. The cylinder block is mounted over a drive shaft 15 with sufficient clearance to allow limited transverse movement or it may be skewed slightly to the shaft axis. The sleeve 40 extending across the gallery 26 provides a drive between the shaft 15 and the cylinder block 25, the sleeve 40 being connected thereto by shear pins 41. The portion 42 of the sleeve 40 is splined to the shaft 15, the splines permitting a limited eccentricity of the shaft and sleeve. The axial forces in the shoes 32 are balanced by supplying pressurised fluid into recesses 32a through apertures 45 in the pistons 28. A relief valve 46 prevents excessive build up of pressure in the gallery 26 and the pins 41 are designed to shear at a torque corresponding to the maximum permissible pressure in the outlet passage 37.
Patent GB-435863-A (GB)
Title: Improvements in the manufacture and production of organic compounds containing alkylradicles of high molecular weight
Filed: 1934-03-26
Abstract: Amines are prepared by causing halogen sulphonic acid esters of aliphatic, cycloaliphatic or mixed aromatic-aliphatic alcohols with at least 8 carbon atoms to react with basic reacting nitrogen-containing inorganic or organic compounds.  Suitable nitrogen-containing compounds are: ammonia, hydrazine, hydroxylamine, aliphatic or cycloaliphatic amines, polypeptides, albuminous substances, tertiary and aromatic amines, and substituted amines such as those containing halogen atoms.  The halogen sulphonic acid esters may be those derived from natural wax alcohols or the alcohols obtained by reduction of fatty acids, resin acids or naphthenic acids, such as octyl, dodecyl, myristyl, cetyl, octodecyl and oleyl alcohols; or those derived from unsaturated alcohols such as olein alcohol; or they may be esters of polyethyleneglycol monoalkyl ethers or of alcohols of low molecular weight containing aliphatic radicles of high molecular weight such as ethyleneglycol monododecyl ether chlorsulphonic acid ester, or methylhydroxyethyl palmitic acid amido halogen sulphonic acid esters, or halogen sulphonic acid esters of other carboxylic acid esters, carboxylic acid amides or esters which contain an aliphatic radicle of at least six carbon atoms.  The reaction is generally carried out under mild conditions, for example, at comparatively low temperatures as from -30 to 40 DEG  C., and in the presence of solvents or diluents, and if the conditions are mild in the presence of water, alcohol or aqueous alkalies, hydrolysis then not occurring.  Aminosulphonic acids or sulphamic acids are bye-products of the reaction.  In examples, chlorsulphonic acid dodecyl ester dissolved in ether is reacted with liquid ammonia at -30 DEG  C. to produce a mixture of the corresponding primary, secondary and tertiary amines; the same ester is allowed to flow into a solution of dimethylaniline in spirit at 0--5 DEG  C. to give dodecyldimethylamine; dodecyltrimethyl ammonium is made from the same ester and a solution of trimethylamine in spirit at 0--5 DEG  C.; dodecyl chlorsulphonic acid ester is reacted with triethanolamine dissolved in alcohol at 0 DEG  C., there being produced triethanoldodecyl ammonium salt which dissolved in water gives a solution of great foaming power; chlorsulphonic ester of phenylethyl alcohol is run into a solution of dimethylamine in alcohol at 10 DEG C. to give phenylethyldimethylamine.  The halogen sulphonic esters are made by reaction of aliphatic, cycloaliphatic and mixed aliphatic-aromatic alcohols of high molecular weight with excess of sulphuryl chloride.

Filed: 1924-04-16
Abstract: 215,336. Wolf, H. May 1, 1923, [Convention date]. Hydrocarbons, cracking.-In cracking heavy hydrocarbon oils, the oil is pumped under a pressure of 20-300 atmospheres through a steel coil in which the oil is heated to 400-450‹ C. and is maintained at that temperature for 30-80 seconds. The gases and vapours formed during the cracking expand immediately after leaving the coil through a valve into distilling-columns. The oil is passed through the coil at a speed exceeding one metre per second. The reflux oil from the columns is returned for passing again through the coil, and the oil supply is preheated in the columns. The Specification as open to inspection under Sect. 91 (3) (a) also included examples in which the oil was maintained at a cracking-temperature for 100 seconds and 167 seconds.

Title: Process for producing beta-olefins
IPC: C07C5/25
Filed: 1942-07-13
Abstract: Terminally unsaturated olefins having no branching of the carbon atom chain at the double bonded carbon atoms and containing at least four carbon atoms are isomerized to the corresponding secondary b -olefin by contact with a metal of Group VIII at 35-150 DEG  C., in the substantial absence of hydrogen.  The catalyst may be prepared by impregnating particles of activated carbon with an aqueous solution of cobaltous nitrate, drying, and heating in presence of hydrogen to form the metal.  Examples illustrate the conversion of butene-1 to butene-2, and the process may also be applied to the isomerization of pentene-1, hexene-1, the higher homologues, 3-methyl-pentene-1, 4-methyl-hexene-1, and 4-phenylhexene-1.  If isobutylene is present with the butene-1, it is preferably removed before the reaction to prevent coating of the catalyst with polymers, and saturated hydrocarbons, which have a diluting action, are also removed.

Gravity, measuring force of.-Comprises apparatus for recording the path of a sphere moving under the influence of gravity from the periphery to the centre of a horizontal plane which can be rotated about a vertical axis. The plane 5 is suspended by three equal cords 2 equally spaced around its periphery and fixed at their upper ends to a tube 1. A cord 3 supporting a weight 7 passes up through the tube 1 and then down to a pin 4 to which it is secured, the pin being passed through a post 14 in which it is held by a spring clip 11. The sphere 6 is attached to a cord 8 passing through a hole at the centre of the plane 5 and attached at its lower end to a weight 9, a perforated tab through which the pin 4 passes being fixed to the cord. To release the sphere the plane 5 is turned about the vertical through about one revolution so that one of the cords 2 presses the cord 3 against the tube 1. The plane 5 is then held whilst the pin 4 is pushed upwards. The plane is then released and commences to turn until the cord 3 is released when the weight 7 pulls out the pin 4 and releases the sphere which commences to move towards the centre of the plane. The plane having been covered with a sheet of paper and the sphere with marking material, a record of the path of the sphere relatively to the plane is produced.

Title: Improvements in or relating to rotary engines, pumps and the like
IPC: B21B17/12
Filed: 1934-03-29
Abstract: 414,010. Rotary engines. SPHAEROGES., 17, Neue Gr³nstrasse, Gleiwitz, Berlin. March 29, 1934, No. 9857. Convention date, Aug. 14, 1933. [Class 110 (ii).] A rotary engine or pump comprises a rotary shaft 4, part spherical side-walls 5, 6, cheek members 7 and an inclined trunnion 8, which support a non-rotating piston 11. The faces 10 of the members 7 are inclined to a plane perpendicular to the shaft and spherical casing 1, and co-operate with faces 17 on the piston to form working chambers 15. A stationary partition 13 fits into a slot 14<a> in a conical pin 14 which is fitted into a hole in the top of the piston. During rotation of the shaft 4 the piston oscillates to and fro and also moves into close proximity to surfaces 5<a>, 6<a> which are rotating. Cut-away parts 16 on these surfaces have a conicity approximately equal to that of the piston surfaces 17. The length 22 of the surface 16 must be greater than or equal to the width 23 of the hole 12. The parts 17 on the piston may be radial or converge the walls 5<a>, 6<a>, being modified accordingly. Grooves 27 are formed in the piston in which eddies are formed for packing purposes. The surfaces 16, 17 do not come into contact, one or both surfaces being ground down to provide a clearance between the surfaces at the end of a stroke. The angle 21, Fig. 1, is smaller than the angle of oscillation of the piston 11, i.e. smaller than twice the angle 18. Recesses 30 and scraping edges 31 are provided to prevent choking of the pump by fibrous or granular material.
Patent GB-916919-A (GB)
Title: Improvements in the analysis of mixtures of substances
IPC: G01N30/86
Filed: 1959-03-23
Abstract: In a process for analysing gases by gas chromatography, wherein the result is recorded on a recording medium moving at a speed which is inversely proportional to the time elapsed after injection of the sample into the column, the movement of said medium is commenced when a substance not interacting with the absorbent appears in the effluent.  The substance not interacting with the absorbent is normally air.  The length of the recording <PICT:0916919/III/1> medium is reduced and in addition graphs may be obtained which can be directly compared.  Thus the position of the records for various substances may be marked on the recording medium or a correspondingly marked transparent cover element may be placed thereon before analysis.  Fig. 2 illustrates a preferred apparatus for obtaining the desired movement in a recording cylinder 9. When the sample is introduced into the apparatus an electric motor (not shown) is actuated which drives a disc 1 having a pin 2 which (in operation) bears upon a dog 3 on a disc 4 mounted on the driving shaft 51 of a transition mechanism 5 so constructed that the speed of the driven shaft 511 is inversely proportional to the time elapsing from the beginning of the rotation of 51.  It is stated that the pin and dog arrangement 2, 3 eliminates the initial speed range in which the output drive should theoretically be infinitely great.  The driven shaft 511 carries a disc 6 on which is mounted a driving pin 7 adjustable in accordance with a graduated time scale 8: after a period of time determined by the adjustment made, the pin comes into contact with a dog 10 and thereafter drives the recording cylinder. The position of the pin is set to introduce a time delay corresponding to the previously determined time required for the air peak to appear.  The movement of the cylinder is linked by means of a drive to a logarithmically wound potentiometer 13 so that in half a revolution of the cylinder the potentiometer completes a full revolution corresponding to a range of one order of magnitude: the signal Um from the detector of the chromatographic column is fed into the potentiometer and a corresponding signal Us is obtained therefrom, the latter being thereby increased with time.  This is employed to control the stylus 11 producing the recording as a result of which the later peaks of the recording are proportionally increased and progressive flattening of the graph eliminated.
