Patent GB-775813-A (GB)
Title: Recovery of phenols
Inventor: JACOBS DAVID IAN HUTCHINSON
IPC: C07C37/08
Filed: 1955-02-09
Abstract: A process for the manufacture of resorcinol by the catalytic cleavage of a reaction mixture containing meta-di-isopropylbenzene dihydro-per oxide derived from the oxidation of meta-di-isopropylbenzene is characterized by the step of decomposing by the action of heat the material contained in the cleavage reaction product which is less volatile than resorcinol while passing an inert gas through the reaction product and simultaneously distilling off the additional quantities of resorcinol and the meta-isopropenylphenol so formed. The decomposition is preferably effected at a temperature within the range 170 DEG  to 300 DEG C. and more preferably between 200 DEG  and 270 DEG C. The initial cleavage product is preferably first treated to remove or neutralize the catalyst (e.g. sulphuric acid) and stripped of low boiling materials such as acetone and unchanged hydrocarbons. The heat treatment may be applied after removal or partial removal, before removal or concurrently with the removal of the main batch of resorcinol from the cleavage reaction product. Specified inert gases are steam, nitrogen, carbon dioxide and flue gas, the steam being preferably superheated and, if desired, generated in situ by heating an aqueous solution of the cleavage reaction product.  The steam is preferably employed in such a volume that the resulting vapour phase when condensed forms a 20 to 40 per cent aqueous solution of resorcinol.  Alternatively, the vapours resulting from the passage through the inert reaction product are condensed into water until a 20 to 40 per cent aqueous solution of resorcinol is obtained.  Where an inert gas which cannot be condensed is employed such gas, after removal of condensable vapour, is preferably recycled to the reactor in which decomposition takes place.  The resorcinol and meta-isopropenyl phenol are preferably separated from one another by selective solvation, e.g. using benzene, toluene, a - or b -methylnaphthalene or mixtures thereof, or chloroform or carbon tetrachloride.  The vapours containing the resorcinol and metaisopropenyl phenol may be passed directly into the selective solvent, and when steam is employed as the inert gas two layers are formed, an aqueous layer containing resorcinol and an organic solvent layer containing the metaisopropenyl phenol.

Abstract: 1,203,903. Making tubes. CEMENTIFERA ITALIANA FIBRONIT S.p.A. 27 Jan., 1969, No. 4500/69. Heading F2P. A method of manufacturing tubes comprises the steps of forming from an aqueous slurry of a fibrous material a sheet 7 thereof, dewatering the sheet 7 on a permeable support 4, winding the sheet 7 on a mandrel 8 to form a tube 9 and continuing the winding in one or more localized areas only to form a local increase in the outside diameter of the tube. Sockets may be formed, with or without a sealing ring groove, in the increased diameter portions by a machining operation (Fig. 7, not shown). The sockets may be formed, however, by placing sleeves on the mandrel after the manufacture of the basic tube 9 at the position of the to be formed sockets (Fig. 6, not shown). The windings at the localized areas may be carried out in an installation to which the initially wound tube 9 is immediately moved, the installation comprising two winding assemblies (Figs. 5, 6, not shown). Alternatively, as shown, a gate 13 having sidewalls 14 (15, Fig. 1, not shown) is lowered by pneumatic or hydraulic actuation into the sheet 7 to prevent a central area of the sheet from forming. A spigot and socket tube is formed from the manufactured tube by a cutting process.

Title: Improvements in or relating to shoe-upper conforming machines
IPC: A43D21/12
Filed: 1947-02-18
Abstract: 621,322. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and CHOICE, F. C. Feb. 18, 1947, No. 4652. [Class 17 (i)] Detailed improvements are made in the lasting machine described in Specification 598,164 with a view to improving its performance. (a) The work engaging portions of the upper jaws of the three grippers are opened to an unusually wide angle, i.e. some 50 degrees relatively to the lower jaws before the commencement of the cycle of operations, to facilitate insertion therein of the margins of uppers of different materials and thickness, as they extend outwards at an angle from the last, when the shoe is presented to the machine. Relative movement of approach of the gripper jaws from wide open to gripping positions is performed in two stages by cam-operated mechanisms, the first stage which is performed 'by an auxiliary closing mechanism after the lasting margin has been placed in the jaws closing them to a position similar to that occupied by the jaws of the earlier machine after which, and after the machine has been started into power operation, the upper jaws are closed on the work and the grippers moved bodily to tension the upper by means similar to those employed in the earlier machine. (b) Stripping devices having prong-like portions 197, Fig. 10, pivotally mounted in shrouding recesses 199 in the lower jaws 15 of the side grippers, are forced from their recesses, as the grippers are returned in opened position of the jaws to initial position after completing an operation, to strip upper material which may adhere to the lower jaws due to adhesive from a toe stiffener being present thereon. (c) The return movement of the shoepositioning fingers to operative position is delayed, compared to the earlier machine, by a latch device, which is released, when the other parts of the machine reach their final position of rest, to enable the operator to remove the shoe from the machine without danger of fouling the fingers. (d) Disturbance of the last in the shoe upper in the machine due to movement at an early stage in the cycle of operations, longitudinally of the shoe, of the toe end gripper is prevented by providing means, in addition to and independent of those which move the gripper heightwise of the shoe to impart tension to the upper, which impart to the gripper movement away from the last with a component lengthwise of the last after a considerable portion of the upper tensioning movement of the gripper heightwise of the last has taken place. A heel end abutment engages the upper after the side grippers have started to tension the upper to reduce the tendency to forward thrust.
