Patent GB-887755-A (GB)
Title: An improved method of siliconising a vitreous surface
IPC: C03C17/30
Filed: 1960-02-23
Abstract: <PICT:0887755/III/1> A vitreous surface of an article that has been heat treated to establish the distribution of internal and/or superficial stresses therein is siliconized by bringing a preheated organosiloxane siliconizing medium into contact with the surface while the latter is at a temperature which will cause the organosiloxane to become polymerized on to the surface, the temperature of the siliconizing medium being such that it will not produce a substantial thermal change in the surface so that changes in the distribution of said stresses is avoided.  The process may be carried out while the article is still hot from or still undergoing the establishing treatment.  Cyclic organosiloxanes and linear organohalogenosiloxanes or their esterification or etherification products, in the form of a gas, vapour or mist at a temperature in the range of 150 DEG  to 300 DEG  C. may be used.  As shown (Fig. 1), the selected organosiloxane is introduced from container 2 into the vaporizer 1 where it is heated by the heating element 3 to a temperature corresponding to a given vapour pressure.  A carrier gas from vessel 6 is passed via the feed line 7 where it is heated by heater 8 to the scrubbing coil 1a into the liquid, becoming saturated with organosiloxane vapour.  The saturated carrier is passed to a mixing chamber 13 where it is mixed with vapour free carrier gas in order to bring the organosiloxane content to the desired value, and at the same time the temperature recorded by thermometer 18 may be adjusted if necessary.  A catalyst-water vapour, sulphuric acid vapour or organosilyl ester vapour-may be introduced via line 17 into the mixing chamber.  The siliconizing medium then passes along line 15 to the treatment area A which it enters at the header 20, the temperature being adjusted by heater 16.  From the header the medium passes into funnel 23 via a series of ports and comes into contact with the surface of the article 39, remaining in contact with it as it flows along the narrow passage 26 to the funnel 24.  From here the exhausted medium is drawn by pump 19 to the cooler 5, the carrier gas passing over into vessel 6 and being recirculated.  Traps 27 are provided to prevent communication between the funnels and the surrounding atmosphere, and if a thermal radiator 28 is to be used beyond the funnel 24, traps should be employed to prevent communication between funnel 24 and the radiator, and between the radiator and the atmosphere. Additional catalyst may be fed to the radiator 28 via line 29. Modifications for treating rod-like articles and the interior surface of a bottle are described.

Abstract: 325,702. Pescara, R. P. Feb. 27, 1929. Two-stroke-cycle engines.-In a direct acting compressor wherein the floating pistons 1 are connected together by rods 4 and levers 6 to move synchronously, the compression pressure within the combustion chamber is raised by ejecting a part of the air charge during the first part of the compression stroke. The levers 6 are mounted on fork shafts 5. A valve 15 is raised a variable amount for this purpose by a cam 12 on a rock shaft 5 acting through a lever 14, whose fulcrum is adjustable either manually by the lever 27 of by fluid pressure acting in the piston 18. The lever 14 may act directly on the valve spindle or as shown through a blade spring 31, a dashpot on the valve spindle prevents sudden movement.
Patent GB-719330-A (GB)
Title: Polymeric cation exchangers
Filed: 1952-03-12
Abstract: Cation exchangers, insoluble in water and weakly alkaline solutions, are produced by copolymerizing water or water-alcohol mixtures in (1) a water-soluble, unsaturated, polymerizable, monocarboxylic acid and/or water-soluble salt thereof with (2) a water soluble unsaturated polymerizable organic compound which contains at least two polymerizable ethylenic groups and which may be between 0.01 and 40 per cent. of the total monomers.  Examples of (1) are acrylic and methacrylic acids, which may be partially replaced with fumaric acid, and of (2) are the reaction products of polyamines with acrylic or methacrylic acid, e.g. ethylene diacrylamide or the trimeric reaction product of formalin and acrylonitrile.  Water-soluble polymerizable organic compounds containing no acid or salt group, such as acrylamide, methacrylamide and acrylonitrile, may also be present. Catalysts which may be used are hydrogen peroxide, persulphates and, in particular, combinations of the latter with reducing compounds such as sodium bisulphite and formamidine sulfinic acid.  The copolymers are separated from their gels by evaporation of the solvent, addition of electrolytes, freezing out or the removal of water with another solvent.  In examples the trimeric product of formalin and acrylonitrile is copolymerized with (1) sodium acrylate; (2) and (3) acrylic acid.  The exchangers produced have marked swelling capacity and have therapeutic uses.
Patent GB-939180-A (GB)
Title: Flaking of menthol
Inventor: BAIN JOSEPH PAUL
IPC: B01J2/24
Filed: 1962-02-20
Abstract: <PICT:0939180/IV(a)/1> A process for comminuting normally solid menthol comprises forming a melt of the menthol, applying a film of the molten menthol to a chilling surface controlled between a temperature of 0 DEG F. and at least 10 DEG F. below the initial congealing point of the melt, maintaining the dew point of the ambient atmosphere about the chilling surface below the temperature of the chilling surface, permitting the film to congeal at least to a plastic state, removing the congealed film from the chilling surface, and converting the removed film into particulate form.  In the apparatus shown, a molten mass of 1-menthol, 11, maintained in a steam-jacketed pan, 12, has a rotating cylindrical cooling drum, 13, dipping therein to pick up a film, 14, of the menthol approximately 20 mils thick.  Molten 1-menthol, 17, is fed into the pocket between the drum and a steam-heated feed roll, 16. Chilled water is fed continuously into the drum, 19, at a temperature of 60 DEG F. and continuously withdrawn, 21, at a temperature less than 1/2  DEG F. above the inlet temperature. The eventual menthol film approximately 30 mils thick is gradually congealed in travelling from the feed roll, 16, to a doctor knife, 15, into a brittle, frangible, solid film.  As the film contacts the knife it breaks completely into small white flakes, 22.  By turning off the heat to the feed roll and rotating the cooling drum more slowly, the menthol film is removed by the knife as a continuous integral sheet which can be immediately sliced into small, regular polygons with conventional tools and the polygons rapidly made brittle by passing them through cold, dry air prior to packaging.  If desired, the menthol is fed into a pocket between a pair of cooling drums rotated in opposite directions. Alternatively, a conventional belt cooler or a deformable drum cooler may be used.  Other coolants, e.g. refrigerants such as halogenated hydrocarbons, ammonia or propane may be used instead of chilled water.
