Title: Improvements in or relating to means for retaining solids in tubes
IPC: B01J8/06
Filed: 1959-05-07
Abstract: <PICT:0921906/III/1> To retain contact bodies in a vertical reactor tube 11, Fig. 1, but permit the free flow of liquids, a spring 13 is inserted in the lower end of the tube, the spring retaining itself in the tube by its resilience.  Preferably the lower end 16 of the spring is bent inwardly and extends across the centre of the tube, this end being gripped to twist the spring in order to reduce its diameter for easy insertion into and removal from the tube.  In Figs. 4 and 5 (not shown) the spring is in the form of a cylindrical helix, each end being bent inwardly so that the spring may be inserted either end up.  Alternatively, the spring may be a conical helix, or a flat spiral with the inner end bent axially and then radially, (Fig. 3, not shown).

Title: Process for the preparation of aromatic mono carboxylic acids
IPC: C07C51/265
Filed: 1955-05-02
Abstract: Aromatic monocarboxylic acids are prepared by reacting in liquid phase an aromatic compound having an aliphatic nuclear substituent oxidizable to a carboxy group, with molecular oxygen in the presence of a catalyst comprising in conjoint presence bromine and a heavy metal oxidation catalyst.  Specified heavy metals are manganese, cobalt, iron and nickel.  The metal and bromine may be added in ionic form, for example as the metal bromide or as separate salts, one containing the metal and the other bromine.  Alternatively the metal may be present as a carboxylate and the bromine added as a non-metallic or organic bromide.  The oxidation process is preferably carried out in the presence of an inert organic medium, preferably a saturated aliphatic monocarboxylic acid containing 2 to 8 carbon atoms, or benzoic acid.  Pure oxygen or a mixture of oxygen and inet gases, such as air, may be used.  The process may be carried out batchwise or continuously and partially oxidized material may be separated from the product and recycled.  Water may be removed from the reaction mixture, for example by distillation or by adding acetic anhydride.  Sufficient pressure is applied to the reaction system to maintain a liquid phase.  Specified starting materials are methyl-, ethyl-, isopropyl-, n-butyl- and sec.-butyl-benzenes, tert.-butyl-toluenes, a - or b -methyl-naphthalenes, acetophenone, benzaldehyde, a -tolualdehyde, benzyl or phenethyl alcohols, acetonaphthones, naphthyl-methanols or ethanols, and a -naphthaldehyde.  In examples a mixture of ethylbenzene, acetic acid and manganese bromide is treated with air at a temperature of 196 DEG C. and 400 pounds per square inch pressure to give benzoic acid; p-tert. butyl-toluene treated similarly gives p-tert. butyl-benzoic acid.

Abstract: 515,536. Colour photography. ODLE, J. E., MOEN, L., and TULL, A. G. June 2, 1938, No. 16499. [Class 98 (ii)] Colour photographic material comprises a support carrying a single non-colour-sensitized emulsion layer, portions of which are colour sensitized for desired spectral ranges in the form of separate areas of sensitization each of which occupy less than half the width and a fraction of the length of the material. As shown the film 1 includes areas 2, 3 and 4 each occupying less than half the width of the film and sensitized for different spectral regions, each group of areas 2, 3 and 4 together occupying a normal film frame. The green and red sensitizers may be erythrosine and pinacyanol respectively. The sensitizing solutions may be applied by rollers having peripheral projections corresponding to the areas to be sensitized, or the rollers may first apply the sensitizing solutions to an endless inhibition matrix that travels in contact with the film during one section of its travel. Alternatively the sensitizers may be applied to the film or to the matrix by reciprocating pads. In a further modification, a resist is applied to the film at the parts not required to be affected by the particular sensitizing solution; the film is dipped bodily into the sensitizing solution, the resist and excess sensitizer are removed and the process repeated for the other areas to be sensitized. Areas on both sides of the median line may be left unprotected by the resist and the film may first be dipped edgewise into the sensitizing solution up to the median line and then reversed, and the other edge dipped into a second sensitizing solution. The film may be exposed in a beam-splitting camera and a minus-blue filter may be placed in the path of the light to the green and red sensitized areas and a red filter in the path of light to the red sensitized area.
