Patent GB-390549-A (GB)
Title: Improvements in the manufacture of hydrogen peroxide
IPC: C01B15/03
Filed: 1931-10-14
Abstract: <PICT:0390549/III/1> Hydrogen peroxide is obtained by distillation from a solution of persulphuric acid or a persulphate by concentrating the solution under diminished pressure until not more than half of the persulphate or persulphuric acid has been hydrolysed and then completing the hydrolysis in a distillation step under diminished pressure substantially without further evaporation of water in the presence of steam.  The above process may be part of a continuous cycle, a solution of sulphuric acid or ammonium or other bisulphate circulating through an electrolytic cell consisting of a single chamber without diaphragms and a still in which the above steps take place.  A persulphate solution is fed by a feeding device such as described in Specification 358,654 into a battery of steam-jacketed vacuum tubes a.  The concentrated solution leaving tube a flows down a column b filled with Raschig rings and provided with a heat-insulating jacket f.  The vapours generated in the tubes also enter the column.  Steam enters a pipe c and leaves with the hydrogen peroxide vapour by a tube d to enter a condenser or rectifying column (not shown).  The whole apparatus is under reduced pressure, the residual bisulphate solution leaving through a sealed barometric column e.  The introduction of steam through a pipe such as c may be omitted, the steam passing from the tubes a with the liquid determining the hydrolyses and carrying off the hydrogen peroxide vapours.  The steam and hydrogen peroxide will then leave the column at its lower part. The apparatus may be kept under a reduced pressure of 1\ba1/2\be inches of mercury, the tubes being heated by steam at 10 lbs. per sq. in. pressure and the hydrolysis and distillation column having a temperature of 70-80 DEG  C. Instead of a column filled with Raschig rings, a column containing perforated plates or bubblers may be employed.

Filed: 1953-10-17
Abstract: 727,008. Duplicating-machines. RENAUER, A. Oct. 17, 1953, No. 28703/53. Class 100 (2). A flat-bed hectographic duplicating-machine comprises a bed 1 to which the mirrorscript original 3 is attached and a carriage adapted to reciprocate over the bed on guide rails 2. Bell crank levers 7 pivoted to the carriage walls 13 at 9 carry a tray 11 for guiding copy sheets to printing position and an impression roller 10. The front wall of the tray has a lip 11a adapted to co-operate with a moistening felt 12a projecting from a container 12 also pivoted on the carriage walls 13 and spring-loaded through bar 22 on arms 21 to an upper position so that overmoistening of the tongue is prevented. The original 3 is clamped to the bed by a clamping bar 4 acting against resilient inserts 16. A stopbar 5 is provided to limit entry of the copy sheet as shown in Fig. 1. After insertion of the copy sheet the levers 7 are rotated downwardly by handle 8, causing the impression roller 10 to move into pressure engagement with the flat bed thereby causing the leading end of the copy sheet to bend up and enter a take-off guide formed by a member 15 as shown in Fig. 2. Also the lip 11a comes into operative position to urge the copy sheet against the moistening felt 12a. Movement of the carriage across the bed will then cause, in a single operation, moisten. ing, printing and removal of the printed sheet through the guide-way formed between the member 15 and impression roller 10. At the end of the printing stroke the handle 8 is lifted so that on the return stroke the roller 10 is out of engagement with the mirrorscript original 3. Since forces are applied to the mirrorscript original 3 in one direction only it is only necessary to provide clamping means at one end.

Abstract: 279,896. Laughlin Fitter Corporation, (Assignees of Laughlin, W. C.). Oct. 30, 1926, [Convention date]. Density separators; discharging; driving. - A tapered rotary casing forms an annular material chamber in a centrifugal separator and the material passes from the chamber between helical flanges on the outside of the chamber wall, the flanges being enclosed by another casing rotating at a, speed different from that of the first casing. One end 22 of the shaft 12 is hollow to form an intake for the material which passes through the apertures 38 into the chamber 37 formed inside the conical rotor 30 carried by the shaft. The outer face of this rotor carries two worm threads 42, 43 and these are surrounded by a casing 70 supported by a rotor 62 on a sleeve 60 geared to the shaft 12. The small ends of the rotors project into a box 13 which forms a discharge box for the separated solid material. The outer rotor has a plate 66 spaced from the rotor plate 62 and provided with a central aperture through which the separated liquid passes into the annular chamber 67 from whence it passes through the passages 68, 83 to the annular chamber 84 and the discharge pipe 85. The shaft 12 is driven by means of a chain 51 from a suitable motor 53, Fig. 6, and the shaft 12 is connected to the sleeve 60 by gearing 54, 56, 58, 59, so that the rotor 62, 70 rotates at a slightly lower speed than the inner rotor 30. When the material is fed into the machine it passes into the chamber 37, is thrown outwards by centrifugal force and passes through the apertures 44 to points between the worms 42, 43. The liquid then passes on to the discharge chamber 84 and the solids are forced along the worms to the chamber 13. The ends of the worms are notched as shown at 86, 87 so that the solid material comes to rest before its discharge, and any liquid accompanying it is then forced back along the cone by centrifugal force.
