Patent GB-403402-A (GB)
Title: Improvements in or relating to the production of aliphatic ethers
Filed: 1932-05-30
Abstract: <PICT:0403402/IV/1> Ethers are produced by passing the vapours of the corresponding alcohol over a dehydrating catalyst and passing the reaction products preferably in vapour form, into a rectifying column in which the alcohol and water are condensed while the ether passes off as vapour and is separately condensed.  Preferably the alcoholic condensate is treated in a second column to separate the alcohol which is returned to the process.  The alcohol vapour may be preheated by heat exchange.  The reaction temperature may be 175--500 DEG  C. for methanol, and the pressure may be 15 atmospheres, but pressures up to 200 atmospheres may be used.  The space velocity (at N.T.P.) may be 200--30000 per hour, but preferably about 5000. Suitable catalysts are alumina, partially hydrated alumina (obtained by heating the hydroxide at 300 DEG  C.) partially hydrated titanium oxide, barium oxide, silica gel, basic aluminium sulphate, and aluminium phosphate.  When methanol is employed, all apparatus with which it contacts prior to its conversion, should be composed of or lined with aluminium or other material which does not catalyze its decomposition to carbon monoxide.  In the apparatus shown the liquid alcohol is supplied at 1 with recirculated alcohol from a pipe 30 and is passed through a pump 2 and pipe 3 to a heat exchanger 4 where it is vaporized by the heat of the reaction products which enter at 9 and leave at 10.  The alcohol vapour then passes to a second preheater 6 which may be heated electrically to about the reaction temperature, and then by a pipe 7 to the reaction chamber 8.  The reaction products pass by pipe 9, heat exchanger 4 and pipe 10 to a cooler 18 or its byepass 14 and thence by a pipe 17 to a distillation column 19 having heating coils 20.  Ether passes off by a pipe 25 to a condenser 26 and is withdrawn at 27.  The liquid effluent from the column 19 is passed by a pipe 21 to a column 22 from which the alcohol is returned via the pipe 30.  The uncondensed vapours from the catalytic synthesis of methanol may be employed for this process, the preheaters then being unnecessary; the pressure is reduced to the desired extent before admitting to the reaction vessel.

[Also in Groups V and X] Apparatus for manufacturing prestressed reinforced concrete elements (see Group V), comprise a flexible endless conveyer on which a series of moved parts are hinged about parallel axes and which can be moved at right angles to said axes through a downward arc whereby the moulded elements are released. The conveyer comprises chains 7 passing over driving sprockets S and idler sprockets 6, and the mould parts, which are of inverted U form with side walls 9 and upper walls 10, are fixed to links in the chains so that they lie across the latter. The mould parts may be long enough transversely to mould bars 30 feet long. Concrete is deposited from a hopper 16 into a box 23 wide enough to overlie two mould parts. The upper runs of the chains, supported on channels 13, pass through a steam chamber 26. When the chains pass round the sprockets 5 their flexure causes the mould parts to separate and the moulded concrete bars drop out and are received on inclined bars 27 which tilt about pivots 28 and lower them on a roller conveyer 29 between the rollers of which they pass. Pre-stressed reinforcement is incorporated by wire clamped to trolleys which are carried along with the conveyer. The trolleys run on rails which diverge and cause the wire to be stretched. The lower runs of the chains move past washing water jets 14 and mould oil jets 15. Specification 427,213, [Group V], is referred to.

Abstract: 273,485. Igranic Electric Co., Ltd., and Willans, P. W. June 28, 1926. Thermionic modulating systems.- The vibrating-element of a buzzer or vibrator moves in response to variations in plate current of an oscillating thermionic valve, and the grid potential is controlled by the movements of the vibrating- element. As shown in Fig. 1, an oscillatory circuit 3, 4 is connected at three points to the three electrodes of a valve v. The plate connection includes a block condenser 5, and the filament connection an interrupter 1. The direct plate current is fed to the plate through a choke 6 and flows through an electromagnet 2 associated with the interrupter 1. When the switch 1 is closed, plate current flows through the valve and oscillations are generated in the circuit 3, 4. The magnet 2 then attracts the interrupter 1 and opens grid circuit. As the oscillations die away, the grid assumes a negative potential and the cessation or reduction of plate current allows the interrupter 1 to close again. The interrupter is thus kept in vibration. The oscillatory circuit may be a radiating aerial, which will emit an interrupted series of waves. The electromagnet 2 may be in a circuit connected by a transformer to the plate circuit; and the switch 1 may be shunted by a grid leak and condenser.
