Patent GB-433550-A (GB)
Title: Manufacture of bituminous dispersions
IPC: C08L95/00
Filed: 1934-02-16
Abstract: Coarse bituminous dispersions using water insoluble organic substances, such as humic acid, lignic acid or similar bodies; acids of high molecular weight, phenol-like bodies, soot, finely ground resins, waxes or pitches as emulsifying agents are obtained by using such proportions of bitumen and water that a stiff magma which is difficult to stir is obtained.  Fused bitumen and water are added alternately, preferably while cooling, to a paste of the emulsifying agent containing little water.  After each addition of bitumen, stirring becomes difficult.  Water is then added until the mass can just be stirred again.  Alternatively, the components are added at two or more parts of the dispersing vessel, so that at some points stirring is impossible owing to the addition of bitumen, and at other points, the mass can be stirred owing to the addition of water.  The product is a stiff mass which is diluted after the final addition of bitumen to form a dispersion containing about 50 per cent of bitumen. According to an example, into 500 pts. by weight of a 40 per cent paste of free-lignic acid, obtained by wet grinding in a colloid mill or by precipitation of an alkali solution, is run, while stirring, a fused bitumen at 90--100 DEG  C., until stirring becomes difficult. Water is then added until stirring can just be resumed.  These steps are repeated until all the bitumen is added, when the mass is diluted to obtain a dispersion containing 50 per cent bitumen. In all, about 2000 pts. by weight of bitumen and 1500 pts. by weight of water are added.

Title: Improvements in or relating to liquefaction of silicone rubber gum and products thereof
Inventor: HUMPHREY BINGHAM JOHNSON
IPC: C08G77/38
Filed: 1953-02-26
Abstract: A solid dimethyl polysiloxane product is liquefied by subjecting it to the action of hydrogen chloride, bromide or iodide or thionyl-, acetyl-, benzoyl- or phthalyl-chloride. Uncured or cured silicone rubbers may be so treated.  In example (1) a shredded dimethyl silicone rubber is treated with gaseous hydrogen chloride under reduced pressure at 70 DEG  F. until a viscous liquid is obtained, and this may be resolidified by (a) exposure to air, (b) blowing or bubbling air or nitrogen therethrough, (c) gentle heating, (d) introducing water or steam to dissolve the HCl, or (e) by neutralizing the acidity with ammonium carbonate or caustic soda. Reinforcing pigments such as titania or diatomaceous earth may be incorporated in the liquefied silicone, as in example (2) wherein diatomaceous earth was made into a paste with CCl4 and mixed with the liquefied silicone rubber of example (1), after which the CCl4 was removed by heating. The product was then milled and cured with benzoyl peroxide.  The liquid silicone may be used for impregnating materials such as textiles of fabrics, paper, glass and asbestos, and regenerating the silicone in situ by contact with air or water vapour.  The silicon-bonded hydrocarbon radicals may be chlorinated in the presence of ultra-violet radiation.  On treatment with gaseous ammonia the liquid silicone yields an oil which on heating forms a sticky gum suitable for joining silicone rubbers together.  This ammoniated oil may be treated with the specified acidic agents to yield a solid rubber, but excess reagent re-initiates liquefaction. The liquefied rubber may be stabilized by adding glycerol and heating to 130 DEG  C.  In reclaiming silicone rubber which e.g. has been used for coating glass fabric, the rubber is liquefied, filtered to remove the filler and glass fibres, and regenerated to its solid form as above described.

Abstract: 116,078. Paschall, B. S. Nov. 17, 1917, [Convention date]. Antitoxins and immunizing and like serums; bacteria, cultivating. - An immunizing or curative preparation for the treatment of tuberculosis, leprosy, &c. consists of organic derivatives of higher fatty acids, higher alcohols, and hydrocarbons separated from the waxy substance of tubercle and other bacteria and used separately or mixed together. Rapidly-growing non-virulent tubercle bacilli or other acid-fast organisms, such as timothy, milk, or grass bacilli, are cultivated, with periodical shaking, in a medium prepared from brewer's or distiller's yeast, dried skim milk, glucose, and salt, and are filtered off, washed, dried below 80‹ C. out of contact with oxygen or metals, cooled, and ground. Material so prepared is saponified by means of a mixture of alcoholic potash solution and benzol, and the resulting solution is decanted, diluted with water, and neutralized with dilute acid or carbon dioxide. Hydrocarbons and alcohols are removed by shaking the solution with hot benzol. The remaining alcoholic solution is acidified to precipitate the insoluble fatty acids, which are filtered, washed, dried, dissolved in ethyl alcohol. and esterified by the addition of an excess of sulphuric acid or hydrochloric acid gas. The esters obtained are washed and are then ready for use. Amides may be obtained by treating the esters with concentrated ammonia. The benzol solution is distilled to remove most of the solvent, washed with dilute acetic or hydrochloric acid, and distilled to remove the remaining benzol. The mixture of alcohols and hydrocarbons remaining is dried, boiled under a reflux condenser with acetic anhydride, and cooled, and the resulting solution of acetates of higher alcohols is drawn off and treated with hot water, so that the acetates separate and may be collected, washed, and dried. Colouring-matter may be removed from the acetates by treatment with chlorine, or by exposure to sunlight. The remaining hydrocarbons are purified by repeated boiling with acetone, and esters of their alcohol derivatives are prepared. The mixture employed for injection consists preferably of salicylic esters of the hydrocarbons, acetic esters of the alcohols, and ethyl esters of the fatty acids; but salicylic esters of the alcohols may be used if desired.
