Patent GB-491996-A (GB)
Title: Improvements relating to the refining of oils by the edeleanu process
IPC: C10G21/10
Filed: 1937-07-08
Abstract: <PICT:0491996/III/1> In the process of removing water from sulphur dioxide in a solvent recovery apparatus of an Edeleanu plant, which consists of stage evaporators, a rectifying column and a receiver, the sulphur dioxide undergoing dehydration in the rectifying column is treated with partly dried sulphur dioxide introduced from the receiver as irrigating and cooling liquid, whereby a reflux effect is obtained.  The sulphur dioxide vapours treated are preferably derived from the extract evaporators operating at low temperature and at a pressure above condenser pressure, which vapours contain substantially all the water in the system, but raffinate evaporator vapours may also be treated.  In a modification, the sulphur dioxide in the receiver only is treated by evaporating one portion in the rectifying column, and treating these vapours with another portion used as irrigating liquid.  A series of evaporators consisting of heaters 1a . . . 5a, and separators 1b . . . 5b, are connected to a condenser K, a receiver S, and a rectifying column R filled with plates or Raschig rings.  An extract solution of a lubricating oil in sulphur dioxide is delivered by a pump P1 at a pressure of 12 atmospheres through a heater 1a, maintained at 65 DEG  C. into separator 1b.  The wet vapours pass to heater 2a maintained at 50 DEG C., and the extract passes through an expansion valve V1 whereby the sulphur dioxide is liquefied and then revaporized in the heater 2a, and passes to the separator 2b working at condenser pressure. The vapours from the separator 2b may be injected directly into the rectifying column R, or may pass to the condenser K.  The vapours enter the middle of the rectifying column and rise against a descending stream of liquid sulphur dioxide from the receiver S. Water collects in the lower part of the column, and the dehydrated sulphur dioxide vapours pass to the condenser K.  If desired, the main part of the vapours are derived from evaporator 3b, in which case a dephlegmator D is used on the evaporator 2b to retain the water in the system.  The vapours from the low pressure evaporators 4b, 5b are recompressed and pass to the condenser K. If several stages of high pressure evaporation are employed, the main dehydration may be effected on vapours from the first evaporator. Specification 391,308 is referred to.

Title: Production of paper webs
Inventor: FREULER FRED HERMAN
IPC: B31F1/22
Filed: 1965-05-06
Abstract: An extensible paper web is made by reducing the width of a paper web, by an amount not exceeding the natural contraction capacity of the web, by forming a series of lengthwise corrugations spaced across the web and drying the web by bringing it into contact with at least one heated metallic surface, so that the crests of the corrugations contact the heated surface and the portions of the web between the crests contract to produce a substantially smooth-surfaced web.  As described with reference to drawings (not shown), paper in an incompletely dried state is passed over a bowed roll with a cover of rubber having circumferential grooves.  The paper is applied to the roll on the outwardly bowed side, is forced into the grooves by compressed air, or a brush or simply by its own tension, and leaves the roll, in a condensed state, on the inwardly bowed side.  The drying of the paper is then completed, e.g. between a conventional dryer roll and a felt.  The paper may be passed over the bowed roll more than once or more than one such roll may be provided if necessary to give enough condensation.

Filed: 1925-08-07
Abstract: 260,062. Tennant, W. J., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Aug. 7, 1925. Drawing to Specification. Vacuum tubes. - In the process of depositing hafnium or zirconium or both on an incandescent body by heating the body in an atmosphere containing one or more iodides of the metals to be precipitated, the iodides used are free from impurities to such an extent that the metals precipitated are ductile. To secure this degree of purity the metals may first be precipitated on an incandescent body from ordinary pure iodides; a second core body and some iodine are then placed in the operating vessel, which is heated, and, owing to the presence of the metals previously deposited and of iodine, iodide vapour of the required purity is produced for depositing the metals on the second core. Alternatively, the initial refinement of the metals may be effected by annealing them in a vacuum. The core body is preferably heated to such a temperature that the precipitated metal grows as a single crystal in a direction at right-angles to the surface of the body, namely 1750‹ C. for hafnium and 1600‹ C. for zirconium.
