IPC: C10G32/02
Filed: 1930-03-05
Abstract: <PICT:0351576/III/1> Volatile impurities such as air and water are removed from liquid or solid hydrocarbons by the high frequency field effect of electric waves of 100 metres or less, i.e. of a frequency of 3 X 10<6> Hertz or more.  Different impurities may be removed in turn by the successive action of waves of different frequencies. The process is also applicable to the drying of tobacco, wood, plants, &c., and other organic materials.  In an example, electric insulating oil in a vessel 6 is treated between condenser plates 5 or within a coil situated between the anode 2 and the grid 3 of an electron discharge tube 1; the anode pressure is obtained from a continuous current battery 8, the cathode 4 is heated by a battery 9, and an inductance 7 is arranged in the grid circuit. The oil may be agitated to quicken the treatment.  Preferably the substance treated is passed continuously through the field of the condenser or coil, as by providing the vessel 6 with inlet and outlet pipes, or by arranging solid matter to be treated on a conveyer passing between the condenser plates or through the coil. Specifications 301,929 and 301,930, [both in Class 1 (i), Chemical processes &c.], are referred to.

Title: Improvements in or relating to the production of magnetisable powder suitable for the manufacture of permanent magnets
IPC: C22C33/02
Filed: 1953-03-18
Abstract: Magnetisable Fe-base alloys containing a minor proportion of Co and/or Ni are produced in the form of powder consisting of particles of mean size not greater than 1 micron in the greatest dimension by mixing powdered Fe oxide with an organic salt of Co and/or an organic salt of Ni, which salts are decomposable between 300 DEG C. and 425 DEG C. for example formate, acetate or oxalate, mixing being carried out so as to obtain a uniform dispersion of the salt or salts in the mass of oxide.  The mixture is then heated in a reducing atmosphere in the range 300 DEG C.-425 DEG C. for 2-3 hours. 0,5-5 per cent of finely divided Zn may be included in the initial mixture in which case reduction is effected in 1-2 hours. Finely divided Mg or Al may also be added to decrease the time required for reduction as described in Specification 743,791. Other metals such as Cu may also be added, e.g. in the form of organic salts.  The organic salt or salts used may be added in the form of finely divided powder or as a solution in a suitable liquid the resulting paste being dried and crushed before reduction to metal.  The Fe oxide used is preferably Fe2O3 in the anhydrous or hydrated form.  The mixture may be subjected to agitation during reduction as by passing hydrogen, the preferred reducing agent, through the powder at the reduction temperature.  The resulting powder preferably contains 5,0-35,0 per cent Co or Ni or both together in the range 10-40 per cent.

Title: Improvements in and relating to dynamo-electric machine
IPC: H02K23/20
Filed: 1943-05-12
Abstract: 565,934. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. May 12, 1943, No. 7537. Convention date, May 13, 1942. [Class 35] To improve the amplification of a cross-field machine and its speed of response to changes in the control field excitation, the machine is so constructed that the magnetic circuit of the control field does not carry fluxes due to either primary or secondary armature reaction. For this purpose the armature core is formed in two portions 10, 11, magnetically insulated by a spacer 12 and each portion has a corresponding magnetically separate stator core. As shown in Fig. 1, the stator cores 22, 25 are supported by a frame 26 of non - magnetic material or of magnetic material of small cross-section. The control field exciting winding 20, Figs. 1 and 2, is arranged on the poles of the stator core 22 and primary armature reaction 24 in this core is compensated by polar windings 23 connected across the primary brushes 16, 17. Secondary armature reaction fluxes 27 are suppressed by polar windings 28 which also embrace the core 25 and carry the load current of the machine. In the modified construction shown in Figs. 4 and 5, the two polar sections of each stator core, as well as the two cores 35, 36 themselves, are magnetically insulated by non-magnetic shims 38, 39 and the sections of one core are displaced circumferentially 90 electrical degrees from the sections of the other core. By this means primary armature reaction flux 41, whilst having paths 42 in the sections of the stator core 36 is suppressed in the stator core 35 carrying the control field winding 33 by the non-magnetic shims 38. Secondary armature reaction 43 is suppressed in both stator cores in the core 36 by the non-magnetic shims 39, and in the core 35 by compensating windings 44 carrying the load current.
