Patent GB-597446-A (GB)
Title: Improvements in or relating to organic compounds containing sulphur
IPC: C07D339/06
Filed: 1945-08-17
Abstract: Organic compounds containing the structure <FORM:0597446/IV/1> or tautomers thereof are prepared by reacting, preferably in a medium substantially free from any hydroxylic solvent (e.g. in diethyl ether), carbon disulphide with a dry alkali-metal derivative of a compound of the general formula Q-CH2-COOR1 wherein Q represents -COOR2, -COR3 (which is generally hydrolysed away during the reaction), or -CN, and R1, R2 and R3 are each a hydrocarbon group, preferably an alkyl group, and reacting the product with an alkyl salt or ester.  The alkyl group in the alkylating agent may contain substituents, which in some cases, such as that of chloracetic ethyl ester, may lead to a further condensation to form compounds in which the <FORM:0597446/IV/2> grouping forms part of a ring.  Such compounds are also obtained by effecting the alkylation with di-salts or di-esters, e.g. alkylene dihalides such as ethylene dibromide or trimethylene dibromide or trimethylene dibromide.  Specified monovalent alkylating agents are methyl, ethyl and higher alkyl halides, of which the iodides are particularly suitable, dialkyl sulphates, e.g. dimethyl or diethyl sulphate, alkyl p-toluene sulphonate and benzyl halides or sulphates.  The products may be further subjected to alkaline hydrolysis, which may be followed by dry distillation.  In examples: (1) the sodium salt of diethyl malonate is reacted with carbon disulphide in anhydrous ethyl ether and the product alkylated with methyl iodide; (2) as in (1) with ethyl alcohol present; the product on hydrolysis with alcoholic caustic potash and dry distillation yields ketene dimercaptal; (3) the sodium salt of ethyl acetoacetate in anhydrous ethyl ether is reacted with carbon disulphide, refluxed with ethyl alcohol and alkylated with methyl iodide; (4) the sodium salt of ethyl cyanacetate is reacted with carbon disulphide in anhydrous ether and the product alkylated with methyl iodide; (5) as in (2), but instead of alkylating with methyl iodide the product is refluxed with ethyl chloracetate; (6) the sodium salt of diethyl malonate with carbon disulphide in anhydrous ether is reacted and the product alkylated with ethylene dibromide followed by hydrolysis with sodium hydroxide; (7) as in (4) using ethyl iodide instead of methyl iodide as the alkylating agent; (8) as in (7) using benzyl chloride instead of ethyl iodide as the alkylating agent; (9) as in (7) using trimethylene dibromide instead of ethyl iodide as alkylating agent, followed by hydrolysis and distillation in vacuo.  Specification 549,201 is referred to.

Title: Process for the manufacture of the alkali salts of sebacic acid or the free acid
IPC: C07C51/295
Filed: 1951-09-12
Abstract: A process for the manufacture of sebacic acid or an alkali metal salt thereof comprises heating castor oil or the fatty acids obtained therefrom with a caustic alkali and water at an elevated temperature and pressure in the presence of cadmium or compounds thereof and isolating the sebacic acid or alkali metal salt thereof from the reaction mixture.  Water must be added when castor oil is employed as starting material but is produced by neutralization when ricinoleic acid alone is used.  Caustic soda or casutic potash are suitable alkalis.  A layer of cadmium gradually forms on the walls of the autoclave and then a special addition of cadmium can be omitted; or cadmium coated autoclaves may be used initially.  Hydrogen may be vented continuously or portion-wise during the reaction or on completion thereof. Foaming may be prevented by maintaining in the apparatus a pressure above the saturation vapour pressure of water. The mixture of reaction products is dissolved in or diluted with water and monobasic acids remaining are separated by fractional precipitation with acid, the sebacic acid being then precipitated by further acidification, especially from hot solutions.  Sebacic acid and its salts may also be separated by fractional extraction with organic solvents.  The mixture of alkali salts may be treated to obtain esters, which, for example, may be useful as plasticizers. Alkali sebacates may be obtained from the mixture by partial acidification followed by free sebacic acid.  In the examples castor oil, caustic soda and cadmium oxide are heated together in a copperlined steel autoclave, the pressure is released, the contents of the autoclave are dissolved or diluted with water and acidified with sulphuric acid to precipitate monobasic acids.  Any octanol or octanone formed is removed by steam distillation, the monobasic acids are removed and sebacic acid is isolated by further acidification of the hot solution. The results obtained are compared with those obtained using steel autoclaves without copper linings and in the absence of cadmium.

Title: Information processing system
IPC: G11B7/241
Filed: 1967-05-09
Abstract: 1,117,419. Facsimile apparatus. NATIONAL CASH REGISTER CO. 9 May, 1967 [11 May, 1966], No. 21481/67. Heading H4F. The Specification describes apparatus for producing a micro-image 18a, Fig. 1, of an original 30, using a laser light source 1 for scanning the original and for producing the micro-image. A beam splitter 3 diverts 10% of the laser energy to scan the original. Lasers 25 and 28 and mirror 26 direct the diverted beam 2b on to a revolving (A, axis C) and rocking (B, axis D) mirror drum 13 to produce a television type scan on the original 30, via lenses 24 and 29. The light reflected by the original is detected by photo-cell 38, and the resulting output thereof is fed to a light modulator 6, either directly for real time reproduction, or via a storage medium. The light modulator may comprise a Pockels cell 6 modulating the plane of polarization of the laser beam 2a and an analyser converting the polarization modulation to amplitude modulation. The amplitude modulated beam is caused to describe a television scan on lens 14 in synchronism with that on original 30 by means of drum 13. A lens 17 then focuses the image of the original on the record member 18. The scanning spot on member 18 is 2 microns in diameter and the image 3 mm. x 3 mm. The member has space for 100 images, controls 40 varying the position of the member. Light source 32 and cells 34 and 35 provide horizontal sync. pulses and cells 36 and 37 provide vertical sync. pulses. The laser beam may be used to read out the image on member 18, the beam passing therethrough falling on cell 42. The image may be projected on screen 23 by means of light source 19 and lens 22. The same beam may be used for original scanning and reproduction, by placing beam splitter 3 &c. just after lens 14, and moving the analyser from the Pockels cell 6 to between said beam splitter 3 and mirror 16 (Fig. 5, not shown).
