Abstract: ABSTRACT OF THE DISCLOSURE           Concentrated aqueous solutions of formaldehyde  are manufactured by the oxidative dehydrogenation of methanol with air in the presence of a silver crystal catalyst bed and of steam, at a temperature from 550 to 780°C, followed by absorption, in water, of the formaldehyde formed.  According to the invention, the reaction is carried out with a throughput of from 1 to 3 tonnes of methanol per square meter of catalyst bed cross-section per hour in the presence of from 0.1 to 1.8 moles of water and from 0.04 to 0.4 mole of formaldehyde per mole of total methanol fed to the catalyst, the formaldehyde and from 0.1 to 1.8 moles of water per mole of total methanol fed to the catalyst are taken from the reaction mixture after the reaction and added to the starting mixture, and (a) a part of the formaldehyde and water is abstracted from the formaldehyde solution, formed in the absorption stage, by means of the air fed to the reaction, at from 60 to 90°C, or (b) a part of the formaldehyde solution formed in the absorption stage is vaporized and recycled to the reaction, or (c) simultaneously a part of the formaldehyde and water is abstracted from the formaldehyde solution, formed in the absorption stage, by the air fed to the reaction, at from 60 to 90°C, and a part of the formaldehyde solution formed in the absorption stage is vaporized and recycled to the reaction.  The formaldehyde solution obtained by this process may be used as a disinfectant, tanning agent, reducing agent and starting material for the manufacture of synthetic resins, adhesives and plastics.

Abstract: Abstract:            A rail clip for securing for example a crane rail to a girder, comprises a first part to be securely attached, e.g. by welding or bolting, to the planar surface of the girder adjacent the rail, and a second part to be fixed to the first part independently of attachment of the first part to the girder.  The second part has a lateral face for abutment with a lateral face of the rail and the parts have laterally facing cooperating surfaces by which forces applied by the rail to the clip assembly are transmitted via the second part to the first part of the clip assembly.  The co-operating surfaces are inclined to the direction of extent of the rail and the second part has an elongate aperture for receiving the fixing means. The elongate aperture is elongate in the same direction as the co-operating surfaces to permit relative adjustment movement between the parts while maintaining the co-operating surfaces in contact.  The first and second parts are oppositely wedge shaped, the first part decreasing in thickness in the direction of approach of the co-operating surfaces to the rail so that lateral forces applied by the rail to the clip assembly produce and are resisted by an increase in the tension in the fixing means.
