Title: Process for preparing a solid substance containing ethyl alcohol
IPC: A23L27/30
Filed: 1967-05-05
Abstract: 1,138,124. Lactose anhydride and ethyl alcohol. J. SATO. 5 May, 1967 [14 May, 1966], No. 21086/67. Heading A2B. [Also in Division C6] Lactose anhydride is treated with ethyl alcohol so as to cause the ethyl alcohol to be asborbed by the lactose anhydride. An additive such as flavouring, colouring, medicament or perfume may be associated with the lactose anhydride and/or the ethyl alcohol before the absorption treatment, or with the treated product. Additives: flavouring agents such as fruit juice extract, hop extract, dried bonito extract, spice extract, amino acid, common salt, malt extract, glycerine, sodium cyclamate, tartaric acid, malic acid, succinic acid, sodium malate, potassium malate and sodium bicarbonate, alcoholic beverages such as brandy, whisky, sakÚ, wine or beer (also cocktails), colouring agents such as caramel, medicinal agents such as a vitamin or hormone, and perfume agents. According to the Examples: (1) 33 Kg. of crystalline lactose are heated to remove the water of crystallisation and to obtain 30 Kg. of lactose anhydride, in which 20 Kg. of ethyl alcohol are absorbed with stirring to produce about 50 Kg. of powder. The powder can be used in confections such as chocolate or chewing gum. Alternatively, the powder is dissolved in water to produce an alcoholic beverage. (2) A mixture of lactose anhydride and condensed grape juice is dried to obtain lactose anhydride containing a condensed fruit juice, and 95%-ethyl alcohol, in which a small amount of a perfume agent and glycerine have been dissolved, is absorbed by the lactose anhydride. The product is then mixed with tartaric acid, malic acid, succinic acid, potassium malate and colouring to give a "grape wine powder". The powder can be formed into granules, lumps or tablets. (3) 95%-ethyl alcohol containing dissolved ingredients of hops and malt, is absorbed on lactose anhydride. The product is then mixed with amino acid powder, caramel powder, malic acid, tartaric acid and sodium bicarbonate to give a "powdered beer". (4) A seasoning is prepared by absorbing an extract of bonito in ethyl alcohol, on lactose anhydride prepared by spray-drying a solution of crystalline lactose in an aqueous extract of bonito. (5) 99%-ethyl alcohol containing dissolved orange juice and perfume, is absorbed on lactose anhydride containing gelatin and sodium cyclamate. The product may be added to the raw materials used in the production of cakes.

Patent GB-479057-A (GB)
Title: Improvements in the production of polyvinyl resins
IPC: C08F8/12
Filed: 1936-07-30
Abstract: Relates to resins produced by condensation of a hydrolyzed polyvinyl ester and a substance containing a reactive carbonyl group, e.g. an aldehyde or a cyclic ketone.  Such resins are de-esterified to contain 3 per cent or less ester groups (calculated as polyvinyl ester), the content of hydroxyl groups calculated as polyvinyl alcohol being increased, preferably to about 10 to 20 per cent for higher (e.g. cyclohexanone or butyraldehyde) acetal groups, and to about 10 to 17 per cent for lower (e.g. acetaldehyde) acetal groups. Preferred de-esterification agents are alkalis, such as caustic alkali or alkali carbonate, or primary or secondary alcohols, such as lower fatty alcohols; and strong acid, e.g. sulphuric or hydrochloric, may be present with the latter; the process may be carried out at from room temperature to 70 DEG  C.  Suitable starting materials are polyvinyl acetal -acetate, -propionate, or -butyrate resins; polyvinyl formaldehyde-, acetaldehyde-, propionaldehyde-, butyraldehyde-, crotonaldehyde-, cyclohexanone-, acetal-ester resins; and polyvinyl acetaldehydebutyraldehyde-acetal ester resins.  The products may be coated from solvents such as methyl alcohol alone or with acetone or methyl acetate to transparent, flexible, and moisture-resistant films; those from polyvinyl acetaldehydeacetal resins are particularly suitable for wrappings and for supports for photographic emulsions.  The products are compatible with plasticizers, e.g. tricresyl phosphate; tri-(n- or iso-butyl or -amyl)phosphates; di-(n- or iso-butyl or amyl) phosphates; 2 : 4 : 6- or other tribromophenol; di- or triglyceryl esters such as acetins, propionins or butyrins; glycerol acetal esters such as the butyraldehyde acetal of mono-acetin, -butyrin, or -valerin; glycerol acetal ethers such as the acetaldehyde acetal of glycerol mono-ethyl or -dodecyl ether; a - or other monochlornaphthalene.  The plasticized resins can be extruded to sheets or plates suitable for use in laminated safety glass, or otherwise moulded.  In examples polyvinyl acetal-ester resins are de-esterified (a) by ethyl alcoholic caustic potash at 70 DEG  C., (b) in pyridine solution by aqueous caustic soda at 40 DEG  C., (c) by ethyl alcohol in the presence of sulphuric acid at 70 DEG C.  Specification 351,082* is referred to.  The Specification as open to inspection under Sect. 91 states that the de-esterification may be combined with the initial condensation, sulphuric acid being used as catalyst, and preferably a lower fatty alcohol as de-esterifying agent, at least 3 mols. per mol. of aldehyde being used.  In an example, polyvinyl acetate, ethyl alcohol, and paraldehyde are reacted in the presence of sulphuric acid and water, the molar ratio of ethyl alcohol to paraldehyde being about 5 to 1, and the product contains 2,2 per cent polyvinyl acetate.  This subject-matter does not appear in the Specification as accepted.

Abstract: 700,828. Train lighting systems. STONE & CO. (DEPTFORD), Ltd. Sept. 3, 1952 [Sept. 17, 1951], No. 21796/51. Class 38 (4) The embarkation lights 13' of an "unequipped" railway coach 2 lit on the block system are controlled by an electromagnetic switch having a main winding 15 connected between the usual paralleling main 4 and lighting main 5, an auxiliary winding 19 in series with the embarkation lamps between the lighting main and negative main 6 and arranged to oppose the main winding, and contacts 16, which are closed when the main winding is unexcited, also in series with the lights 13'. By this arrangement, when the axledriven generator of an associated equipped coach 1 is running above a certain speed and the contacts 9, 10 of its cut-in have changed over, the main-winding 15 is energized by the voltage difference between mains 4, 5 (which may be, say, 2 volts) so that contacts 16 are open and lights 13' extinguished. An auxiliary contact 14 on the generator cut-in extinguishes embarkation lights 13 of the equipped coach 1. At speed insufficient to operate the cut-in the mains 4 and 5 are at the same voltage (due to closed contact 10) so that winding 15 is unexcited and the lamps 13' are thus energized. The opposing winding 19 prevents reopening of contacts 16 by a voltage difference between mains 4, 5 as may arise by the surge of current to the lamps when cold. To relieve winding 15 of the full line voltage, which it would otherwise receive whenever the lighting main 5 is de-energized by opening contacts 12 of a master switch, a second electromagnetic switch is provided having a coil 18 energized from the mains 5, 6 and contacts 17, which are open when coil 18 is de-energized, in series with the winding 15.
