Patent GB-629184-A (GB)
Title: Improvements in or relating to a process for the production of alkali metal alkoxides
IPC: C07C29/70
Filed: 1947-02-26
Abstract: Sodium alkoxide is obtained as a freely-flowing powder by reacting, with agitation, an aliphatic alcohol containing not more than four carbon atoms with molten sodium at a temperature not below the critical temperature necessary for the presence of the solid alcoholate of the alkoxide and in an inert atmosphere, the alcohol being added at a rate sufficient to prevent charring of the product but insufficient to wet the reaction mixture and in sufficient stoichiometric excess to ensure that all the metal enters into combination, and heating the product until alcohol ceases to distil over.  The reaction sets in more rapidly, especially in the preparation of sodium methoxide, when the metal is dispersed, preferably in a mass of the reaction product.  An inert atmosphere may be provided by nitrogen or hydrogen.  Sodium is charged into a jacketted reactor under an atmosphere of nitrogen, the temperature is adjusted and alcohol is run in until the reaction is shown to be complete by the cessation of hydrogen evolution and rapid distillation of alcohol.  The residual alcohol is removed by heating in an inert atmosphere at or above the temperature at which the alcoholate decomposes to give the alkoxide.  The process may be modified for continuous operation by feeding sodium and alcohol separately into one end of a heated horizontal tube divided into two sections and fitted with a longitudinal stirrer.  The reaction takes place in the first section and removal of excess alcohol in the second.  The excess alcohol may be fed back to the reaction zone.  In examples the preparation of sodium methoxide, ethoxide and n-propoxide by the batch process is described.  Triethanolamine, tested as a stabilizer for sodium propoxide did not produce an appreciable effect.
Patent GB-379668-A (GB)
Title: Fuel pump and distributing apparatus for internal combustion engines
IPC: F02M59/00
Filed: 1931-02-23
Abstract: 379,668. Oil engines. OIL ENGINE DEVELOPMENT CO., 538, 5th Street, Columbus, Indiana, U.S.A. Feb. 23, 1931, No. 5662. Convention date, March 22, 1930. [Classes 7 (iii) and 7 (vi).] In a fuel injection system for an internalcombustion engine the fuel is drawn from a tank and fed by a gear pump 24 to a pressure vessel 107 and thence to a distributer 45, comprising two abutting flat plates preferably lined with bronze &c., which controls the suction and delivery of a reciprocating pump feeding all the engine cylinders. The pump plunger 62 is actuated by a cam 46 which rocks a shaft 53 provided with a face 56 upon which rests a lever 57. The output of the pump is controlled by hand and governor by varying the position of the lever 57 upon the face 56. The main supply of fuel to the gear pump 24 is controlled by a valve 86 provided with a projection 96. This valve is opened by the delivery pressure acting upon the piston 95. After the 'system has been dismantled this valve is opened by the plunger 204. The output of the gear pump 24 is controlled by a piston 99 acted upon by delivery pressure and serving to byepass a part of the delivery to suction. A hand pump 169 serves to prime the injectors, pipe lines, pump and vessel 107 as far as the valve 108. A valve 189 serves to connect the priming pump to the system. The leakage from the injectors, which are of the type described in Specification 237,915, [Class 7 (iii), Internal-combustion engines, Carburetting-apparatus &c. for], and have pump plungers incorporated therein, is led by pipe 148 to the casing 19 where it joins leakage from the remainder of the system and is returned to the fuel tank by the gear pump 27.

Abstract: Cobalt-containing catalysts for use in the hydrogenation of furfural (see Group IV (b)) may comprise (1) supported cobalt catalysts containing 50 per cent or more by weight of cobalt, e.g. cobalt supported on kieselguhr and reduced with hydrogen before use or a cobalt-on-carbon catalyst prepared by precipitating a cobalt salt on carbon and reducing with hydrogen; (2) powdered catalysts obtained by crushing granules of cobalt alloy and removing the alloying metal with acid or alkali; such catalysts may be obtained by treating cobalt-aluminium alloys with caustic soda or cobalt-magnesium alloys with an acid; (3) foraminate catalysts prepared by treating granules of cobalt alloys with acids or alkalies so as to remove part of the alloying metals; such catalysts may be obtained by the action of aqueous caustic soda on alloys containing cobalt and aluminium in proportions between 15 : 85 and 55 : 45 by weight.  The catalysts may optionally be used in association with an alkali or base such as sodium carbonate.ALSO:Furfuryl alcohol is obtained by hydrogenating furfural in a batch process conducted in the liquid phase at a raised pressure at 80-120 DEG  C.  Various forms of catalyst are described (see Group III).  The process may be effected at 50-200 atm. pressure and in the presence or absence of an alkali or base such as sodium carbonate.

A method of forming a plurality of deep ribs in a sheet by means of a like plurality of cooperating pairs of rib-forming rolls, includes the steps of deforming to a valley shape a plurality of longitudinal portions of the sheet each having a width substantially greater than the width of the strip of the sheet from which the rib is to be formed and having as its apex the strip from which the rib is to be formed, and acting on each strip with a pair of co-operating rib-forming rolls to form a plurality of deep ribs in the sheet at a single pass through the said plurality of pairs of rolls. Aluminium sheet 12 is drawn over side guides 62, Fig. 2 (not shown), and over a shaping device 10, which deforms it into valley shape, Fig. 5a, and then between shaping rolls 14, 16 which forms a central rib 32, Fig. 5b, returning to the shape of Fig. 5c as it leaves these rolls. The sheet 12 then passes under members 60 and over a central guide 56 engaging the rib 32 and over the members 44 shaped, Fig. 4a, to extend from a flat receiving end 52 to a rounded section end 50 corresponding to the shape of rib-forming parts of pairs of rolls 36, 38 and 40, 42. The strip as it passes through these latter rolls assumes the shape shown in Fig. 5d and after it leaves the rolls the shape shown in Fig. 5e- The rolls 36, 38 and 40, 42 may be positioned sufficiently higher than the central rib 32 to allow it to continue to move in a horizontal path. To form further ribs further rolls are provided positioned progressively higher in relation to the horizontal bed of the machine. In a modification, Fig. 6, rib forming rolls 76, 78 are used with co-operating guides 80, 82. Specification 950,059 is referred to.

[Class 142 (i)] In mechanically operated broken weft finding devices, a bevel wheel b on the dobby shaft a from which the pattern cylinder as well as the lifting knives can be driven, gears with pinions c, d loosely but not slidably mounted on a shaft e. The shaft e is driven by a gear g from a small electric motor f. The pinion c is constantly coupled by a claw i to a claw k on a coupling sleeve l slidable and turnable on the shaft e and normally clutched by a claw m to a loosely-mounted sprocket wheel n driven by a chain o from the loom whereby the dobby is normally driven. A sliding sleeve h keyed to the shaft e is movable from its central inoperative position into engagement with the pinion c or d by a lever p operated by a rod s, which also, by means of mechanism q, r, u, v, w, unclutches the sleeve l from the wheel n. The sleeve h is thus clutched to the pinion c, or d, according to the direction of movement of the rod s, the dobby accordingly being driven forwards or reversely from the shaft e and motor f. After the rod s has been operated to disengage the sleeve l from the wheel n and is freed, the sleeve l, which is now driven from the pinion c, is at the end of a revolution moved again into engagement with the wheel n by a spring g mounted on the hub of the pinion c, the mechanism w, v, r, q, &c. returning the coupling sleeve h to its normal idle position. The rod s may be locked in one or the other coupling position, or may be periodically operated. A modification is described wherein the shaft e is driven from a constantly rotating countershaft.
