Title: Production of unsaturated ketones
Inventor: LACEY RICHARD NORMAN
IPC: C07C45/67
Filed: 1959-01-14
Abstract: Unsaturated aliphatic ketones of the general formula R1.R2.C=CH.CH2.CH2.CO.R3 wherein R1 and R2 are alkyl or alkenyl groups or H atoms and R3 is an alkyl group, are prepared by contacting allyl aceto acetates of the general formula R1.R2.C(CH=CH2).O.CO.CH2.CO.R3 at an elevated temperature, e.g. 100 DEG C.-300 DEG C., with an aluminium enolate of the general formula Al(-O.C.R4=CH.CO.R5)3 wherein one of the groups R4 and R5 is an alkyl group and the other is an alkyl or alkoxy group.  Specified aluminium enolates are the tri-acetylacetonate, obtainable by reacting aluminium sulphate with acetylacetone in aqueous NH3, and a tri-(alkylacetoacetate) obtainable by reacting an aluminium tri-alkoxide with, for example, methyl or ethyl aceto acetate. Examples describe the conversion of (1) 3-methyl but-1-enyl-3-aceto acetate to 2-methylhept-2-en-6-one, the catalyst being omitted in a comparative experiment; (2) 3-methyl-pent-1-enyl-3-aceto acetate to 3-methyl-oct-3-en-7-one; and (3) linalyl aceto acetate to geranyl acetone.

Patent GB-403233-A (GB)
Title: Manufacture of weatherproof luminous substances
IPC: B26B21/20
Filed: 1933-01-16
Abstract: Weatherproof phosphorescent or fluorescent substances are obtained by subjecting to a high temperature a mixture of very pure aluminium oxide with a very pure oxide of calcium, magnesium, zinc or beryllium in the presence of an exciter metal, the latter being employed in such amount that the finished product does not contain more than 0.5 per cent thereof.  A lower limit of 0.05 per cent is referred to.  In place of the metal oxides, decomposable compounds of the metals, e.g. ammonia alum, magnesium sulphate, may be employed.  The purity should be such as is used in the determination of atomic weights.  As exciter metals, manganese, nickel, cobalt, cerium, uranium, iron, copper, rubidium and bismuth are specified.  When necessary, the exciter metal compound is converted into a difficultly volatilizable compound, for instance, a zincate, titanate or ortho-zinc titanate. Such conversion may be effected prior to admixture with the other ingredients, or during the main reaction, by adding say zinc or titanium oxide to the mixture.  The aluminium oxide and other oxide are preferably used approximately in the proportions existing in spinels, and the mixture may be heated to about 1000 DEG  C. until sintered, or to about 2000 DEG  C. or more until fused.  The mixture may be introduced into the oxyhydrogen, acetylene or coal-gas flame of a Verneuil furnace.  Substances lowering the sintering temperature of the mixture may be added thereto.

Patent GB-462222-A (GB)
Title: Colouration of textile and other materials
IPC: D06P1/28
Filed: 1935-07-25
Abstract: Cellulose esters or ethers, dyeing; vat dyes, dyeing with; dye preparations.--Cellulose organic ester or ether materials, in the form of filaments, yarns, threads, foils, films or straws, are coloured by applying thereto a freely fluid solution of an ester of a leuco vat dyestuff in a liquid of which a major proportion is an organic liquid boiling below about 130 DEG  C., said liquid not being a solvent for the cellulose ester or ether, and thereafter developing the colour by hydrolysis and oxidation.  Specified organic liquids are esters, e.g. ethyl acetate and isopropyl acetate, alcohols, e.g. methyl, ethyl, propyl and isopropyl alcohols, and glycol dimethyl- and diethyl-ethers and especially suitable are mixtures of esters, alcohols and water, the ester and alcohol being in such proportions that in admixture they do not form a solvent for the cellulose ester or ether.  The esters of leuco vat dyes may be (a) the salts of acid sulphuric or phosphoric esters of vat dyes of the indigoid or anthraquinone series especially the salts with organic bases, e.g. methylamine, pyridine or triethanolamine or (b) neutral esters, e.g. the alkyl sulphuric esters.  Specified esters are Indigosol scarlet HB, Indigosol OR, Indigosol IRRD and Indigosol printing black. Running threads, foils, straws or fabrics may be coloured by passing them through the solution of the ester of the leuco vat dye and may be thereafter washed to improve the fastness of the dyeing to rubbing by passing them through an organic liquid, e.g. through a bath of the solvent mixture employed for the dye. Alternatively or additionally the fixation may be improved by steaming.  The dyeing solutions may also be applied by bath methods to hanks of thread or to fabrics or may be forced through packages of thread.  In an example, cellulose acetate yarn is passed through a 1 per cent solution at room temperature of Indigosol scarlet HB in a mixture of 40 parts ethyl acetate, 60 parts ethyl alcohol and 20 parts water, dried by passage through warm air and wound on to perforated bobbins and the colour is developed by circulating through the bobbins a solution containing sodium nitrite and hydrochloric acid.  Specifications 282,036, 313,451, and 314,208, [all in Class 15 (ii)], are referred to.

Title: Improvements relating to the driving of air gas apparatus
IPC: C10J1/00
Filed: 1929-01-18
Abstract: 328,213. Smith, H. E., and Smith, R. E. Jan. 18, 1929. Regulating delivery.-In a water-pumping and weight-driven petrol gas apparatus, the weight is lifted by an internal-combustion engine and when fully raised stops the engine; or if the drive be through an epicyclic gearing, the raised weight releases a brake on a gear member to disconnect the drive. The engine also raises water, and after disconnection when the weight is lifted, is automatically stopped when the tank is full. The stopping is effected by closing the throttle or interrupting the petrol supply or ignition. When the weight is fully lifted, a chain 6 thereon moves a throttle lever. The engine 1 drives a water lifting pump 10 and lifts the weight through an epicyclic gearing 12. The shaft 13 is driven by the engine and carries a sun pinion 15 gearing with planet pinions 16 meshing with an internally toothed wheel 17 carrying the driving pinion 14 for the weight. A peripheral brake band 19 on the planet carrier 18 is connected to a lever 22 with a weighted arm 21. A chain 6 on the weight operates, when the latter is fully lifted, a lever 22 with a short arm 23 and a weight 24, which falls on the weighted arm 21, thereby releasing the band brake 19 so that no drive is conveyed to pinion 14. When the tank is filled, an overflow fills the vessel 25, tilts the lever 26 and closes the throttle, &c., by a cord 27, or an overflow device floating in the tank may stop the engine. If the tank 11 is full when the weight is to be lifted, the pump works idly through a by-pass 28,

Plungers 37 working within the moulds are positively projected and retracted by a grooved, stationary cam 35, which is adjustable about a centre 32a, Fig. 2, in order to control the amount of dough received by the moulds, without interference with the discharge positions of the plungers. The cam is locked in adjusted position by studs 32a working within slots 32b. Each mould which passes clear of the supply 23 is for a short interval in communication both with the atmosphere and with the supply, in order to allow air to be expelled from the mould. The receiver 21 is adjustable by a screw 25 and carries a relief valve 27 and pressure gauge 28.
