Title: Process for the toxoidification of bacterial toxins
IPC: C12N7/06
Filed: 1962-03-08
Abstract: Bacterial toxins are converted into toxoids by treatment with glucuronamide e.g. in aqueous solution, preferably at a concentration of 5-10% by weight at temperatures between 10 DEG  and 70 DEG C. and a pH of 4-10.  Specific examples relate to the treatment of toxins of diphtheria, whooping cough, tetanus and staphylococcus.

Title: Improvements in and connected with the distillation of hydrocarbon oils, tars, asphalts, and the like
Filed: 1920-03-27
Abstract: 165,230. Engelke, E. F. March 27, 1920. Mineral oils.-In distilling mineral oils, tars, asphalts, &c., the yield of light distillates is increased and formation of coke is prevented by causing the oils, &c. to flow in extended paths in the stills and treating them with gases containing free hydrogen such as natural gas, distillation gas, oil gas, water gas or blast-furnace gas. The stills may be under ordinary or reduced pressure. Steam may be passed into the stills particularly to treat the residues to increase the flash point. The preheated oil, fed through inlet 3b to a tray T in a horizontal furnace-heated still E, is caused to follow an extended path by baffles and passes by pipes P to a second trav or to the base of the still which is similarly divided by baffles. The residual oil either passes away to the preheater or to the second of a battery of similar stills arranged in cascade. Preheated and compressed gases containing hydrogen are passed through perforated pipes t, t<1> into the oil and through pipes v, v<1>, into the vapour space. Ordinary or superheated steam may be passed through the same pipes. Baffles s<1>, s<2> give an extended path to the vapours to produce reaction between the hydrogen, &c. and the vapours. The vapours from the tray and those from the still bottom may be collected together or may be separated bv a movable baffle d and passed to separate dephlegmators and condensers.

Title: Starch-based polyhydroxy-polyoxyalkylene ethers
IPC: C08G18/48
Filed: 1966-03-02
Abstract: 1,125,046. Starch ethers; polyurethane foams. OLIN MATHIESON CHEMICAL CORP. 2 March, 1966 [26 March, 1965], No. 9146/66. Headings C3C and C3U. A starch-based polyhydroxy-polyoxyalkylene ether is prepared by reacting starch and polyol in the presence of an acid catalyst at elevated temperature and oxyalkylating the mixture with an alkylene oxide, using at least 0À5% by weight of acid catalyst based on the combined polyol and starch, and at least 0À5 mole each of polyol and alkylene oxide per glucose unit weight of starch, after which the oxyalkylated product is reacted with additional starch, acid catalyst and alkylene oxide, using sufficient starch to increase the total molar ratio of glucose unit weight of starch to polyol to at least 2: 1, the proportion of catalyst being at least 0À5% of the combined weight of starch and polyol, and the proportion of alkylene oxide being at least 0À5 mole per glucose unit weight of starch in the additional starch. The starch is suitably corn or potato starch. Specified polyols are glycerol, ethylene glycol, propylene glycol, sorbitol and many other di-ols; specified alkylene oxides have 2-6 carbon atoms; epichlorohydrin and cyclic oxides are also mentioned. A Lewis acid, e.g. BF 3 , is best used as catalyst, but inorganic acids, e.g. HCl, H 2 SO 4  or acids such as fluorosulphonic and p-toluene sulphonic are also mentioned. It is stated that the initial step of the reaction, prior to oxyalkylation, causes degradation of the starch molecule by hydrolysis. In the initial reaction the temperature is suitably 30-200 C., and in the second suitably 100- 200 C. Polyurethanes are prepared from the above ethers by reaction of the ether with a polyisocyanate, using at least 0À7 NCO groups per available OH group, and a foaming agent and in the presence of a reaction catalyst. One-shot or " prepolymer " methods may be used. It is desirable to have a hydroxyl number between 80-300 in the starch ether when used for this process. The foaming agent may be water or a volatile halohydrocarbon.

Abstract: 197,491. Ogden, J. E. L. March 31, 1922. Combined fluid-actuated and mechanical gears. -The piston, b may be actuated by pressure fluid controlled by a cylindrical slide valve m which is moved in one direction by a piston e attached to the piston b and in the other direction by pressure fluid. During the suction stroke, the steam, &c. passes from a pipe p through an annulus r into the space q and lifts a piston k coupled to the piston b. At the end of this stroke, the piston e lifts the valve m, so that steam, &c. enters the valve through a port s and effects the delivery stroke by acting on the upper face of the piston e. During this stroke the steam, &c. passes from the space q into the space above the piston e. At the end of the downstroke, a port t is uncovered by the piston k to exhaust the space u in the valve casing, and a port v is uncovered by the piston e to allow the steam to pass through a passage w to the upper end of the valve and depress it. The steam above the piston e then escapes to exhaust ports n and passage o.
