Title: Improvements relating to radio frequency apparatus for heating gases
Inventor: LINHART JIRI GEORGE
IPC: H05H1/18
Filed: 1956-09-14
Abstract: 855,856. Nuclear fusion reactors. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 13, 1957 [Sept. 14, 1956], No. 28164/56. Class 39(4). [Also in Group XI] Apparatus for preheating a gas for further heating to nuclear fusion temperature comprises a cylindrical container, means for feeding a light gas at low pressure into the container, means for producing a static axial magnetic field in the chamber, and means for feeding electromagnetic energy in the H o1  made axially into the chamber. In the apparatus shown in the figure gas such as deuturium or tritium or a mixture of these is passed through a cylindrical container 1 surrounded by a coil 2 which produces an axial magnetic field ; annular pole-pieces 3 may be provided to increase the magnetic field at the ends of the container. Radio-frequency energy at the cyclotron frequency for electrons is fed into the container so that electrons are supplied with energy which they transfer to the positive ions so that the effective temperature of the ions is raised. The high energy ions may then be subjected to a further process such as cyclotron ion resonance or magnetic shock excitation, to increase their temperature to that at which nuclear fusion reactions occur. The coil 2 may be shielded from neutrons by a beryllium shield 4 or by a jacket of liquid lithium 6 which would produce tritium under neutron bombardment. The container may be cooled by liquid or gas flowing through coolant tubing embedded-in the wall of the containers. Specification 841,253 is referred to.

Patent GB-645140-A (GB)
Title: Improvements in and relating to the production of hydrogen-containing gases
IPC: C01B3/10
Filed: 1947-10-22
Abstract: <PICT:0645140/III/1> In a process for the production of hydrogen-containing gas by the reaction of steam with ferruginous material in an oxidation zone, e.g. at 600-700 DEG  C., followed by treatment of the ferruginous material in a reduction step, e.g. at 900-1000 DEG  C., the ferruginous contact mass is prepared from a coprecipitation in a finely-divided state of ferric oxide and one or more of the refractory compounds alumina, titania, and alumina-silica (i.e. a mixture of oxides which on strong heating gives aluminium silicate).  The ferruginous material, containing, say, not more than 25 per cent refractory compound, may be prepared, for example, by precipitation from a solution of iron and aluminium nitrates by sprinkling in solid ammonium bicarbonate, filtering off the precipitate, washing, igniting at 1000 DEG  C. and finally pelleting. The pellets may be given preliminary treatments at 1000 DEG  C. with hydrogen-containing gas and then with steam to convert ferric oxide to ferroso-ferric oxide.  This material may be maintained in a fluidized condition and may be used in processes where the oxidation and reduction steps are carried out in the same or separate vessels. In the Figure the ferruginous material flows through oxidation vessel 1, oxide heating vessel 3 and reduction vessel 2 under gravity in non-turbulent unfluidized condition at a rate controlled so that, say, 60 per cent of the iron present enters into the reaction.  The material flows, in oxidation vessel 1, countercurrent to steam, pre-heated in heat exchanger 4 by the hydrogen produced, injected at 15 while the hydrogen is withdrawn at 16 and cooled to condense excess steam. Preheated producer gas is admitted to reduction vessel 2 at 25 countercurrent to the material flow, and spent gas is withdrawn at 17, burnt with air in combustion chamber 5, and passed to oxide heating vessel 3 to heat the material to, say, 1000 DEG  C. before reduction.  The hot gases from vessel 3 are withdrawn through boiler 6 and producer gas preheater 7.  The ferruginous material from reduction vessel 2 is returned by "gas lift" 8 through separator 9 to oxidation vessel 1.  The oxide heating vessel 3 may be dispensed with if the steam feed is preheated to 1000 DEG  C.

The cylindrical reservoir is closed by the diaphragm 5 and a glass plate 4 carried on a member 6 which can be unscrewed for re-filling.  Holes 10 are provided to conduct the liquid to the pad, and are flared at 11 to avoid wastage of liquid by capillary action.  Also to reduce excessive flow, an inner felt strip 13 is provided, with the main fibre direction perpendicular to the plane of the axes of the holes 10, while the fibre direction of the pad 12 is parallel to said plane.  A cap 14 is provided to protect the pad.  With the cap removed and the pad downwards, the diaphragm is actuated and the pad is drawn across the surface of the copy sheet.  The diaphragm may be at the side of the reservoir, or at the end as shown, and operated by the operator's thumb or by a press button or rocker arm.  The reservoir may be formed in an aluminium casting carried on a wood or moulded plastic handle as shown, or may be in the handle itself.  Instead of the diaphragm 5, some other form of manually operable pump could be used.

Filed: 1953-10-22
Abstract: Thermoplastic masses are obtained by subjecting wood to two treatments one of which is a reflux condensation in the presence of a condensing medium so as to polymerize the lignin and the other of which is an etherification with benzyl chloride. Ketones, e.g. acetophenone and cyclohexanones, aldehydes, e.g. acetaldehyde, formaldehyde, benzaldehyde or crotonaldehyde and resin builders (substances which can be condensed to form resins), e.g. resorcinol, aniline, phenols, p-toluene-sulphonamide or phenol sulphonic acids are defined as condensation media.  The quantity of aldehydes may be about one third of the weight of the dry ether.  In an illustration wood is benzylated, washed until completely soluble in dioxane, dried and condensed with e.g. acetophenone under reflux in the presence of hydrochloric acid at about 200 DEG  C. until totally soluble in cyclohexanone or acetone, excess ketone then being removed by the addition of a non-solvent, e.g. petroleum ether, and the product washed with aqueous alcohol and dried.  In the thermosetting material thus obtained the condensation product derived from the lignin constituent of the etherified wood plasticizes the whole compound. The product may be purified by dissolving in e.g. acetic ester and precipitating with a nonsolvent or by the simultaneous addition of both a solvent and non-solvent.ALSO:Thermoplastic masses are obtained by subjecting wood to two treatments, one of which is a reflux condensation in the presence of a condensing medium so as to polymerize the lignin and the other of which is an etherification with benzyl chloride.
