Patent GB-573120-A (GB)
Title: Process for the manufacture of alkylated phenyl-isopropyl-amines
Filed: 1943-11-12
Abstract: a -(3,4-Dimethyl-phenyl)-b -aminopropane and a -(3,4-dimethyl-phenyl)-b -methylaminopropane are obtained by the reaction at elevated temperature and pressure of (3,4-dimethyl-phenyl)-acetone with ammonia and methylamine respectively in presence of hydrogen and a hydrogenating catalyst. In an example, the reaction is effected in methyl alcohol solution in the presence of nickel at 70-90 DEG  C. under a pressure of 15 atmospheres.  Specification 28581/38 as open to inspection under Sect. 91 of the Acts is referred to.  3,4-Dimethyl-phenyl-acetone is prepared by treating with concentrated sulphuric acid a -(3,4-dimethyl-phenyl)-aceto-acetonitrile, made by condensing o-xylene with formaldehyde and hydrochloric acid to form 3,4-dimethyl-benzyl chloride followed by double decomposition with sodium cyanide and reaction of the product with acetic ester in the presence of sodium ethylate.

Title: Method of and means for electro-deposition of chromium
IPC: C25D5/02
Filed: 1943-11-13
Abstract: 568,869. Electroplating. HAY, N. L. S. Nov. 13, 1943, Nos. 18936 and 19962. [Class 41] In a method of and apparatus for chromium plating predetermined surfaces of an article or of several articles simultaneously, which avoids the need for covering with wax the surfaces not required to be plated, the predetermined surfaces and contiguous parts of the articles are shrouded by means of a dielectric shroud which supports an anode member between itself and the surfaces and is of suitable configuration in relation to the latter. The shroud may be of insulating material or wax-covered metal. In the application to valve-contacting pads of valve rockers, the arms 3 of the latter are secured by screw bosses 5 and nuts 27 to spigots 25 formed on parallel angle-section limbs 11, 13 of a frame 9, 15, the end-brace 21 of which is formed with a flange 23 forming a support for the aligned bosses 1 of the rockers when the whole assembly is hung by members 37 in a vat. The assembled bosses 1 of each row are all in contact, but the aligned rectangular pads 7 are spaced from one another. The limbs 11, 13 carry a bracket 29 in which is threaded a clamp 31 adapted to press a channel-section ebonite shroud 33 on to the line of rockers. The shroud carries an anode 35 of antimony-lead which is of similar configuration and longitudinal extent, but not wide enough to contact with the rockers. Thus, when the latter are connected as cathodes, a uniform deposit thereon is obtained, while the stray currents to the adjacent parts prevent undesired build-up at edges and corners, and are themselves insufficient to plate the adjacent parts.

Abstract: 788,856. Freewheel clutches. PARKINSON & COWAN, Ltd. June 24,1955 [June 30, 1954], No. 19221/54. Class 80 (2). A freewheel clutch between driving and driven shafts 10, 11 comprises a coiled spring 12, frictionally gripping the shaft ends, engaging at one end an abutment 13 on the driving-shaft and at the other engaging an abutment formed by a recess 18 in a cylinder 15 journalled on the driven shaft. The cylinder 15 is closed at its open end by a gland screw 16, journalled on the driving-shaft, and turned to adjust the distance between the two abutments which controls the compression of the coiled spring 12. A nut 17 locks the gland screw in position. Rotation of the shaft 10 in one direction causes the spring 12 to drive the driven shaft 11, while rotation in the reverse direction unwinds the spring and leaves the driven shaft free. The driven shaft 11 can over-run in either direction. In a modification, Fig. 2 (not shown), the axes of the driving and driven shafts are inclined to each other, and the cylinder 15 is correspondingly curved.

Title: Improvements in or relating to tubular furnaces
IPC: C10G9/20
Filed: 1955-07-04
Abstract: <PICT:0779510/III/1> <PICT:0779510/III/2> Vertical metallic reaction tubes are heated in a refractory walled heating chamber having spaced portions of greater thickness than the intermediate portions, by fluid hydrocarbon burners mounted in elongated tunnels in the thicker portions of the walls, the tunnels being at a plurality of vertical levels and disposed so that streams of hot combustion gas from the burners are directed between the tubes and the adjacent chamber wall. In Fig. 1, showing one of the vertical levels, four burners 16 are mounted in tunnels 15 in thickened portions of the walls, so that the streams of hot gas are emitted obliquely from faces 13 and pass between vertical tubes 18 and faces 14.  In Fig. 2 at each level two burners 26 are mounted in tunnels 25 in thickened portions of walls so that the streams of hot gas pass between vertical tubes 24 and walls 23 of the chamber.  The streams are kept out of contact with the tubes until complete combustion of the gas has occurred, the gases passing round the tubes in a spiral path and diffusing inwardly to form a blanket of oxidized gas around the tubes to provide a continuous oxidizing atmosphere for the tubes.  The gases are withdrawn at the top of the furnace.  The tubes are heated by convection and radiation from the gas and by radiation from the chamber walls.  The tubes may be anchored below the heating chamber, either to a quench tank or to a secondary furnace, and means comprising supports and hydraulic jacks may be provided above the heating chamber to exert an upward tension on the tubes.  Furnaces may consist of a number of such heating chambers.  Specification 517,744 is referred to.

Abstract: A catalyst for the preparation of enol-acetates from ketene and an enolizable organic compound (see Group IV(b)) comprises an equimolecular mixture of monofluorophosphoric acid and difluorophosphoric acid which may be prepared by reaction between phosphorus pentoxide and hydrogen fluoride.  This catalyst, or difluorophosphoric acid alone, may be neutralized with sodium acetate after the enolacetate preparation is complete.ALSO:Enol-acetates are prepared by reaction between ketene and an enolisable carbonyl compound at a temperature of 20-110 DEG C. in the presence of difluorophosphoric acid or a mixture of equimolecular proportions of difluorophosphoric acid and monofluorophosphoric acid as catalyst (see Group III).  The process may be carried out continuously or discontinuously and the catalyst is preferably used in a concentration of 0.01 to 2.0% calculated on the total weight of the reactants.  The catalyst is preferably neutralised (see Group III) before isolating the desired reaction product, acetic acid being formed during the neutralisation.  In examples the following compounds are prepared: (1)-(5) isopropenyl acetate from acetone; (6) a -acetoxystyrene from acetophenone; (7) n-but-1-enyl acetate from n-butyraldehyde; (8) the enol acetate of ethyl acetoacetate; (9) the mono- and (10) the mono- and di-enol acetates of acetylacetone.
