Title: Improvements in or relating to processes for reducing iron impurities in ground calcite, dolomite, magnesite and cryolite
IPC: C03C3/00
Filed: 1943-07-30
Abstract: 567,998. Purifying minerals. PILKINGTON BROS, Ltd., and SHERLOCK, A.. July 30, 1943, No. 12420. Addition to 555,241. [Class 1 (iii)] In a process for reducing iron impurities in ground calcite, dolomite, magnesite, and cryolite, the mineral is treated with an aqueous solution containing titanous sulphate or chloride and a fluorine compound, and then washed. The fluorine compound may be hydrofluoric acid, sodium fluoride, or sodium silicofluoride ; the latter compound may be added together with sodium hydroxide or sulphuric acid to form respectively sodium fluoride or hydrofluoric acid. A preliminary treatment with the titanous salt is necessary when sodium silicofluoride is used, and may also be given when using other fluorine compounds. The minerals are not too finely ground, except in the case of dolomite when this is necessary to expose the impurities. The washing water may be removed from the finely ground dolomite in settling pits, and the mineral dried in currents of warm air or by means of a centrifuge. The purification may be worked as a continuous process in a series of compartments. In an example, the iron content of calcite for use in the manufacture of glass, is reduced from 0.013 per to 0.006 per cent by grinding and grading the mineral, thoroughly mixing with 15 per cent titanous sulphate solution and sufficient water to give a flowable mass, adding hydrofluoric acid and mixing further, and finally washing.

Title: Improvements in alternating current motor groups
IPC: H02K17/38
Filed: 1922-05-04
Abstract: 181,335. Forges et Ateliers de Constructions Electriques de Jeumont, (Assignees of Ateliers de Constructions Electriques du Nord et de l'Est). June 9, 1921, [Convention date]. Alternating-current motors; alternating-current commutator machines.-In an arrangement for regulating the speed of an asynchronous motor by means of a series commutating machine which is cascaded with the rotor and has variable inductances shunted across its commutator brushes, the asynchronous motor is adapted for regulation above as well as below synchronism by reversing the direction of rotation of the fields in the rotor of the main motor and in the stator of the auxiliary commutating machine. Means are also provided for exciting the commutating machine from an external source or from itself when the main machine is at synchronism and accordingly with no potential difference at its slip-rings. The application to a two-phase asynchronous machine is shown in Fig. 1 in which the rotor slip-ring a<1> b<1> and a<2> b<2> are connected to the two sets of brushes e<1> f<1>, e<2> f<2> of the commutator machine through the main stator coils g<1> g<2>. The adjustable shunting- inductances c<1>, c<2> are connected in series with auxiliary stator coils d<1>, d<2> which produce the self-exciting potential. A reversing-switch I is connected in one phase and a simple switch K in the other. To increase the speed of the asynchronous machine from somewhat below to above synchronism, the switch I is thrown so as to reverse the field rotation in one phase of the stator and rotor of the auxiliary and main machines respectively. At the moment of synchronism, both phases are open-circuited by means of the switches I, K and the commutator machine then becomes self-exciting through the winding d<2>, the working circuit being through the brushes e<1>, f<1> and the stator coil g<1>. The brushes of the commutator machine are so set that the main coil g<1> gives a motor action both below and above synchronism. Specification 174,583 is referred to.

Title: Improvements in capacitors employing titanium dioxide dielectric material
IPC: H01B3/10
Filed: 1959-04-15
Abstract: In the production of capacitors employing a titanium oxide dielectric material, a surface composed of a titanium/nitrogen compound is oxidized to form a dielectric titanium dioxide film. The base material may be titanium nitride or a layer of titanium nitride may be deposited upon a base surface for example by vacuum evaporation of titanium in the presence of nitrogen gas.  The base material having thereon, or consisting of, the titanium/nitrogen compound may be surface oxidized, for example electrolytically by employing the titanium nitride base as an anode in an electrolyte such as ammonium tartrate, boric acid or nitric acid, or by heating the titanium nitride base in an oxygen atmosphere, or by ion bombardment with an inorganic oxidizing compound.  According to an example, a film of titanium one micron thick was deposited on a glass target in an evaporation chamber under a pressure of 5-8 x 10-6 mm. of mercury after which dry nitrogen was introduced and the pressure maintained at 10-4 mm. of mercury while evaporation was continued until the film had increased by 1 micron in thickness.  A titanium/nitrogen film having a cubic crystalline structure was obtained and this was then immediately oxidized in an electrolyte consisting of either a saturated aqueous solution of boric acid or an aqueous solution of 3% tartaric acid adjusted to pH 5 by ammonium hydroxide solution. Anodic oxidation was effected with an applied potential of 4-5 volts. The electrode so obtained was employed in conventional manner to form an electrolytic or electrostatic capacitor in conventional manner.  A further example relates to the employment of a titanium/tantalum alloy spluttered on to a silica target in a nitrogen atmosphere as the titanium/nitrogen compound.  Reference is made to the possible presence of aluminium or zirconium in the titanium/nitrogen compound.
