Title: Process for effecting organic condensation reactions involving the elimination of water
IPC: C07C69/24
Filed: 1956-09-17
Abstract: Organic condensation reactions involving the elimination of water are effected in the presence of at least one anhydrous, finely powdered calcium salt selected from silicates, aluminates and aluminoferrites, which combine with the water eliminated to give water-insoluble salts during the reaction.  Specified salt mixtures are a mixture of calcium aluminate and calcium sulphate which, on hydration gives Candlot's salt (Al2O3, 9CaO, 3Ca SO4, 30H2O) and various hydraulic cements. Reactions effected in examples are esterification, amine formation from an alcohol and ammonia and amide and nitrile formation from a carboxylic acid and ammonia.

Patent GB-856827-A (GB)
Title: A process for preparing high-purity uranium values from uranium ore concentrates
IPC: C01G43/00
Filed: 1957-09-19
Abstract: A solution containing uranium substantially free from other metals is obtained by preparing an aqueous solution of a uranium ore concentrate, having a pH from 0.1-3.0, contacting the solution with a solution of a dialkyl phosphate in an organic water-immiscible solvent and separating the resultant uranium-bearing organic phase from the aqueous phase.  The initial solution is prepared by the use of an oxidising agent with a mineral acid, e.g. sodium perchlorate with hydrochloric acid, or with an oxidising acid such as nitric acid; hydrogen peroxide and manganese dioxide are also referred to as oxidising agents, and sulphuric acid is mentioned.  The aqueous solution is then intimately mixed with the organic phase in an extractor.  The preferred dialkyl phosphate is di-(2-ethylhexyl)phosphoric acid and suitable solvents are kerosene, naphtha, heptane or other water-immiscible aliphatic hydrocarbon. The phases are separated and the uranium-containing organic phase may be scrubbed with a small amount of dilute hydrochloric acid and stripped e.g. with sodium or ammonium hydroxide or carbonate solutions or concentrated hydrochloric acid.  If hydrochloric acid is used, the solution may be evaporated to dryness and the resultant uranyl chloride calcined to U3O8, or evaporated to eliminate excess hydrochloric acid (which can be recycled), diluted with water and the uranium precipitated with ammonia as ammonium diuranate which can be calcined to oxide.

Abstract: 1,016,719. Laminates and laminating. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 5, 1964 [July 25, 1963], No. 29534/63. Heading B5N. In a process for the manufacture of laminated articles having a plastic or resinous foam core, e.g. polyurethane foam, a lower sheet of facing material 1 is drawn on to the forward portion of a fixed surface 3 where a nozzle 4 dispenses on to the sheet a liquid mixture of foamforming ingredients in a fan-shaped jet 5. Air from a pipe 6, slotted along its length, blows over the sheet to evenly distribute the foam and the sheet is then drawn over the heated backward half 7 of the fixed surface and the foam 8 starts to swell. An upper sheet of facing material 9 is drawn by the upper conveying surface 11 to meet the rising foam, and the upper and lower sheets of facing material with the sheet of foam between them pass through the nip formed by the upper and lower conveying surfaces 11, 13 setting of the foam taking place as the assembly passes between heated platens 15, 16. The slotted pipe 6 may be replaced by a perforated rotating drum. The dispensing device 4 is attached to a traverse system to move it laterally to and fro across the fixed surface, and may be adjusted vertically. The fixed surface 3, 7 is preferably the upper surface of a platen or box and may contain gaps, which may be bridged by thin lateral supporting members, and through which the lower facing sheet may be exposed to radiant heat. Alternatively, the heating may be by means of electric heating elements or pipes containing hot air or liquid or induction heating. The part 3 may be positively cooled by means of cold liquid or gas pipes or chambers. The facing sheets may both be flexible or one may be rigid, and may be of paper, wood, plastic, metal, rubber, paper-board, plasterboard or asbestos.

Abstract: 995,772. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 1, 1962 [Aug. 25, 1961], No. 29559/62. Heading H3B. One end of a sense line of a magnetic store is coupled to sensing means, the other end being terminated by the characteristic impedance of the line. As shown in Fig. 3, a sense line comprises two sections 30, 32 connected to a differential amplifier 25, each section being connected to ground through impedances 34, 36 equal to the characteristic impedances of the delay lines formed by the sense line. The impedances 42 and 44 may be large so as to obtain a large proportion of the induced signal in the line as the impedances 34, 36 absorb any signal reaching them either directly or after reflection at the amplifier. Several embodiments of matrices are described which include means for gating the output pulse, at a time dependent on the X co-ordinate drive line selected, to allow for the delay characteristic of that section of the sense line associated with the switched core. The differential amplifier effects noise cancellation and the characteristic impedances allow ones at the ends of the sense line to be distinguished from zero's in the centre despite the time lag introduced by the delay lines. Suitable delay means are described with reference to Figs. 7 and 8 (not shown) for the gating circuit.
