Patent GB-735597-A (GB)
Title: Improvements in production of titanium monoxide
IPC: C01G23/04
Filed: 1953-05-22
Abstract: Titanium monoxide is produced by forming an intimate mixture composed of substantially stoichiometric amounts of finely divided titanium sesquixoide and titanium carbide, heating the mixture to a temperature of at least 1400 DEG  C., preferably 1500 DEG  to 1750 DEG  C., in an inert atmosphere, removing the resulting evolved carbon monoxide, and recovering the residual titanium monoxide.  The titanium sesquioxide may be produced by forming an intimate mixture of finely divided titanium carbide and magnesium oxide, zinc oxide or calcium oxide, the amount of carbide being at least stoichiometrically equivalent to that of the oxide, heating the mixture to a temperature within the range of 1000 DEG  to 1200 DEG C. in an inert atmosphere, and removing the resulting evolved carbon monoxide and vapours of the metal component of said oxide from the residual titanium sesquioxide.  The sesquioxide may also be prepared using titanium dioxide in place of the above oxides, or by reducing titanium dioxide in a stream of hydrogen at 1500 DEG  C. The reactants are preferably ground to a particle size of - 325 mesh (Tyler Standard), and the titanium carbide preferably reduced to a particle size of about 1 micron or less; the reactants may then be compacted into pellets, water being used as a temporary binder.  The titanium carbide used should be treated for the removal of iron, e.g. by adding hydrochloric acid to a slurry of the finely divided titanium carbide and subsequently washing the resulting chloride from the solid titanium carbide.  Graphite may be removed by froth flotation, but a sufficient additional quantity of sesquioxide to combine with the graphite may alternatively be added to the reaction mixture.  During the reaction between the titanium sesquioxide and the titanium carbide, carbon monoxide is removed, e.g. by maintaining the reaction zone under a vacuum of 10 mm., preferably about 50 to 100 microns of mercury, or by sweeping the reaction zone with an inert gas such as argon or helium.  When the reaction between the titanium sesquioxide and the titanium carbide is preceded by oxidation of titanium carbide to titanium sesquioxide, a residual excess of titanium carbide in the titanium sesquioxide reaction product may be used in part or wholly as the titanium carbide which is reacted with titanium sesquioxide.  Examples are given, with full operational details.  Specification 711,077 is referred to.

Title: Process and apparatus for destroying insect infestation in bulk products
IPC: A01M17/00
Filed: 1940-09-26
Abstract: 539,883. Centrifugal machines. SMITH, F. S. Sept. 26, 1940, Nos. 14593, 14594, 14595, and 14596. Convention dates, Sept. 26, 1939, Sept. 26, 1939, March 1, 1940, and July 16, 1940. [Class 23] Insect infestation, in flour and similar material in bulk, is destroyed mechanically by crushing or abrading action under centrifugal force against a rotating surface and by passage through a restricted space. A suitable form of apparatus is shown in Fig. 1, in an enclosing casing 10 of frusto-conical shape with a cover plate 11 secured by screws. Flexible conduits 14, 15 are connected to the throat 13 and the lower end of the casing for the admission and removal of the flour. The treating element 16 has a supporting plate 32 with a hub portion 32a carried by the sleeve 31 on the shaft 27 of a motor contained in the casing 25. A series of annular plates 36 is mounted on the plate 32 and are held apart by spacer elements 37. The under faces of the plates slope downwards slightly from the centre outwards to provide passages of diminishing height from the centre outwards while the height through the peripheral part is uniform. The structure is surmounted by a clamping plate 39. The unit formed by the flour treating element 16 and its driving motor 17 is supported by tubular parts 22a, 22b at the top of the motor casing, and two tubular parts 22c at the bottom of this casing are connected to the casing 10. The pairs of tubular parts are arranged at right angles to each other. Cooling air for the motor enters by the upper tubular parts and leaves by the lower. The weight of the whole apparatus is supported upon a resilient ring 21. The flour or other material passes through the throat 13, and is thrown by impeller blades 40 outwards through the spaces between the plates 36. These blades 40 and the arrangement of parts at the centre ensure even distribution of the material. Any insect infestation is destroyed by the compression and deformation produced as the material moves outwards and after passing between the plates drops to the outlet 15 at the bottom of the casing. The dead infestation remains in the treating element which can be dismantled for cleaning after removal of the cover plate 11 and the clamping plate 39. In a modification, the plates of the treating element are of conical or domelike form. In a further modification the plates in the treating element are flat and carry projecting elements M<SP>1</SP> ... M' arranged as shown in Fig. 8.

Title: Improved quick-acting electric voltage regulator for dynamo-electric generators
IPC: H02P9/00
Filed: 1924-06-17
Abstract: 244,803. Dehn, F. B., (Neufeldt & Kuhnke). June 17, 1924. Regulation, automatic.- The voltage of a dynamoelectric generator is maintained constant by means of a quick-acting regulator which controls the speed in dependence upon the voltage, mechanism being provided connecting the powermedium control member and the voltage-responsive member whereby a reaction or back-acting compensation is exerted on the latter to prevent over-regulation, and, in addition, an auxiliary regulator is provided to limit the maximum speed. The generator 1 is driven by a turbine 2 and the voltage is regulated by adjusment of the nozzle needle 3 and by operation of the field rheostat 5. The electric control member comprises an electromagnet 6 connected across the generator terminals and acting upon an armature 7. The armature 7 is connected with the slide 8 of a valve 10 which controls the admission of oil to a servomotor 15 connected to the nozzle needle 3. Another slide 12 is operated by a centrifugal governor 23. Fluctuations in the generator voltage cause the arms. ture 7 together with the slide 8 to rise or fall whereby oil is transmitted through the pipes 13, 14 to one side or other of the servomotor piston 16 to adjust the needle 3 and the rheostat 5. To prevent over-regulation, the piston 16 is connected to the armature 7, through linkwork 18 - - 21, an oil brake 22, and a leaf-spring 44. Similarly, the governor 23 is connected to the armature through linkwork 25, 26, an oil brake 27, and a spring 28. The oil in the brakes is so throttled that rapid movements only are transmitted to the pistons 45, 46, and the total effect is that the armature 7 takes up a position nearer that of equilibrium than would be the case if it were acted upon merely by the electromagnet 6. If the speed of the generator exceeds the permissible maximum, and the slide 8 is in such a position as to work towards an increase of speed, the slide 12 is moved so that oil is admitted through the pipe 13 to close the turbine nozzle. A frequency-responsive device may be substituted for the governor 23. Specification 5945/83 is referred to.
