Title: Improvements in the production of acetone and butyl alcohol by fermentation
IPC: C12M1/12
Filed: 1927-03-14
Abstract: 268,749. Commercial Solvents Corporation, (Assignees of Edmonds, W. J.). April 3, 1926, [Convention date]. Acetone; formaldehyde; methyl alcohol. - In the production of butyl alcohol and acetone by fermentation, the entire series of operations, i.e. the charging and the discharging of the vat and the fermentation itself, is carried out in an atmosphere of the fermentation gases, whereby contamination of the gases with air is avoided; in this way the mixed gases-carbon dioxide and hydrogen-are obtained in a suitable condition for use in the catalytic synthesis of formaldehyde and methyl alcohol, either directly or after removal of part of the carbon dioxide. As shown, fermentation is effected in a vessel 1 from which the gases, escaping under slight pressure through a valve 3, are delivered to a holder 8 through towers 5 - - 7 in which volatile solvent vapours are removed; the tower 5 may be a water- or oil-scrubber and the towers 6, 7 may contain a solid adsorbent such as charcoal or silica gel. Part of the gases is withdrawn from time to time by a pump 12 through a vessel 11 in which sterilization is effected, for example by ultra-violet light, the pump delivering the gases under pressure to a container 13. When fermentation is complete, the valve 3 is closed, the mash is withdrawn through a pipe 16, and the gases enter the vessel 1 through a valve 14. The vessel may then be sterilized by steam admitted through a pipe 15, whereafter the valve 14 is closed, the valve 3 opened, and the fermentation of mash admitted through a pipe 2 is begun.

Abstract: 1,027,251. Yarn tension devices. ERNEST SCRAGG & SONS Ltd. Jan. 30, 1963 [Feb. 26, 1962; May 9, 1962], Nos. 7353/62 and 17784/62. Heading D1D. A tension device for mounting at the top of a two for one twisting spindle is of the tension regulating type so that the amount of yarn on the storage disc tends to remain constant, a condition which it is stated leads to the production of yarn having a more regular twist. As shown the tension device comprises a body 30 which is a push fit in the bobbin and is formed with a circular lip 32 on which lies a disc 42. A collar 33 is rotatably mounted on the body 30 and carries a flyer 34 having a guide eye 43 and has a lever 37 pivoted thereon at 36. The outer end of lever 35 has a guide eye while the inner end carries an upstanding pin 39 and bears down upon a ball 41 set in the disc 42. Weights 40 are loaded on pin 39, alternatively spring weighting means may be used. In operation yarn coming from the package passes to the flyer eye 43, then through the eye on lever 37 and finally between disc 42 and lip 32 whereby it is tensioned. If the yarn tension increases the lever 37 is pulled downwards at its outer end and weights 40 are lifted, thus regulating the tension in the yarn leaving the device and passing to the storage disc.

Patent GB-363909-A (GB)
Title: Process for the production of alumina and alkali phosphates
IPC: C01F7/0673
Filed: 1931-03-11
Abstract: Aluminium phosphate is dissolved in boiling caustic alkali, for example, caustic soda, the solution is cooled, say to 15 DEG  C., to crystallize alkali phosphate, and the mother liquor is employed with fresh caustic alkali to dissolve a further quantity of aluminium phosphate.  This operation is repeated several times, the alkali phosphate becoming progressively more insoluble as the concentration of the alkali aluminate increases, until the solution reaches a certain concentration, when, after precipitating residual phosphoric acid with lime or other suitable metal oxide, it is treated in known manner for the recovery of alumina.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subjectmatter:--The solution obtained by dissolving aluminium phosphate in caustic alkali is treated with organic or inorganic bases forming insoluble phosphates, and the alkali liquors filtered therefrom are returned for further decomposition.  Thus, the solution may be precipitated with baryta, and the barium phosphate treated with sulphuric acid. Barium sulphate filtered from the phosphoric acid is converted to barium sulphide, and this with hydrochloric acid to barium chloride.  Hydrogen sulphide evolved is converted to sulphuric acid for re-use, and the barium chloride is treated with sodium nitrate to produce barium nitrate, from which baryta is obtained. Sodium chloride produced is reacted with sulphuric acid to produce hydrochloric acid and sodium sulphate for re-use.  In another example, the alkali aluminate-phosphate solution is treated with silver nitrate.  Silver phosphate, sodium nitrate, and alumina are deposited, residual soda solution being returned to the leaching. The precipitate is treated with ammonia producing soluble silver-ammonium phosphate, (subsequently decomposing), and a residue of alumina.  The silver phosphate is treated with hydrochloric acid to give phosphoric acid and silver chloride, which latter is decomposed to silver and chlorine.  The silver is dissolved in nitric acid, and the chlorine converted to hydrochloric acid, both products being re-used in the process. Sodium nitrate produced in the process may be converted to potassium nitrate, or may serve for the oxidation of sulphur dioxide produced during the decomposition of sodium-aluminium phosphate by heat (?), or it may be reacted with the barium chloride obtained in the previous example to produce barium nitrate and sodium chloride.  This subject-matter does not appear in the Specification as accepted.

Abstract: 713,173. Feeding sheets. CRABTREE & SONS, Ltd., R. W. Sept. 19, 1951 [April 3, 1951], No. 7723/51. Class 100 (1) In sheet separating apparatus employing pneumatic suckers to which vacuum is applied and cut off in constantly recurring cycles and a handoperated control valve, e.g. a vacuum bleed, can be operated to render the separating apparatus ineffective, means are provided whereby the valve is operated only during the period when vacuum is not being applied to the suckers. By this means derangement of the sheets in the process of being transferred is avoided. The bleed valve is controlled by rotation of a shaft 14. A cam 15 rotating once during each cycle causes, during the period when vacuum is not applied to the suckers, lifting of a push rod 22 pivoted to an arm 18 having a follower roller 17 loaded by a spring 20 against the cam. The handle 12 is mounted on a shaft 13 having an arm 27 connected by a rod 25 to the upper end of push rod 22. A pair of levers 28, 29 pivoted at 30 carry pins 31, 35, the push rod 22 being movable into register with either pin by movement of the handle 12. The levers 28, 29 are connected by rods 32, 36 to lugs 33, 37 on a boss 34 on shaft 14 so that movement of one lever by the push rod will cause rotation of the shaft in one direction and movement of the other lever will cause rotation in the opposite direction. Owing to the action of the cam 15, the push rod 22 is raised only during that period of each cycle when the vacuum is shut off. The handle is retained in either position by an over-centre spring 39.
