CaSO 4  and give a solution of MgCl 2  ( + KC1 and NaCl), which is (i) evaporated to crystallize out carnallite KCl.MgCl 2 .6H 6 O(+NaCl), then (ii) this ppt. is treated with H 2 O to dissolve the MgCl 2  and leave KC1 (+ NaCl). This residue may be added to the kainite before step (c) or may be separately purified and added after step (c), and the final product then contains less MgSO 4 . The mother liquor from (i) and solution from (ii) (both mainly MgCl 2 ) may be spray dried to give solid MgCl 2 .1¢-2 H 2 O. The solution from step (e) may be selectively evaporated, e.g. in 4 stages, to crystallize out K 2 SO 4  and give a solution of MgSO 4  which is added to the mother liquor from step (a). The material floated in step (c) is first crushed and slurried with water containing some of the dissolved salts, and is then subjected to a rough flotation and 3 cleaner flotations. The tailings from the 2nd and 3rd cleaner flotations are passed in countercurrent through the earlier cleaners, and the combined tailings are recycled.

Title: Method of forming metal coatings
IPC: C23C24/08
Filed: 1964-10-12
Abstract: In a process of forming a sintered metal coating on a metal substrate e.g. ferrous base, the substrate is treated with an aqueous solution containing sodium and/or potassium poly-metaphosphate, the powdered metal is distributed on the treated surface which is then dried, compacted and sintered.  The metal powder coating may be Al, Ti, Zr, Ni, Cr, Cu, stainless steel or alloys of any of these metals and the powder is preferably minus 200 mesh.  The substrate may be coated with the phosphate and then coated with the metal powder from a fluidized bed or alternatively the metal powder may be suspended in the phosphate solution which is applied by spraying, brushing, rolling or curtain coating. The solution contains 0.01 - 2g/l of the phosphate and may also contain the following; paraffins, olefins, aliphatic monohydric alcohols, monocarboxylic acids, monocarboxyl compounds, monoamines and mononitriles which impart hydrophobic properties to the coating.  Surface active agents may also be added. The applied coating is dried at 50 DEG  - 450 DEG C., compacted by rolling, die drawing or roller die rolling and then sintered at 400 DEG  - 1100 DEG C. in vacuum or an inert atmosphere.

Title: Electric motor
IPC: H02K37/14
Filed: 1959-12-16
Abstract: 886,092. Electric motors. BEREX ESTABLISHMENT. Dec. 16, 1959 [April 9, 1959; Sept. 29, 1959], No. 42740/59. Class 35. An electric motor, for either step-by-step or continuous operation, comprises a ferrite rotor 9 permanently magnetized with alternate poles around its periphery and a stator 5, 6 with triangular, interdigitated pole pieces 7, 8 which enclose a circumferential energizing coil 1. As shown, there is also an annular ferrite magnet 2 associated with the stator. Under the influence of this magnet the rotor assumes the position shown in Fig. 2, with its poles, shown shaded, beneath the appropriate stator poles. Energization of the coil 1 produces a flux opposite to that of magnet 2, overriding it, and causing the rotor to move one pole pitch. Subsequent de-energization of coil 1 restores the original flux and causes a further rotor movement in the same direction. It is stated that the shape of the pole pieces 7, 8 causes rotation to be in one direction only, to the right in Fig. 2. Thus, the rotor will step round in response to a series of pulses, or if the coil is energized with single phase A.C. the rotor will run in synchronism with the supply, and is stated to be self-starting. In a modification (Fig. 4, not shown) the magnet 2 is outside the stator. It is stated that a second coil may be provided in which current is induced while the rotor moves under the influence of magnet 2, and that this may be used to energize a second motor of this type. In an alternative arrangement (Fig. 5, not shown) the magnet 2 is replaced by a further coil which is energized in the opposite direction to the first and alternately with it through a switching device operated by a cam on the end of the rotor shaft. This arrangement will run continuously on D.C., e.g. for driving motor car auxiliaries such as windscreen wipers. The switching device may have a centrifugally controlled advance/retard mecha- -nism to ensure correct timing of the energizing pulses at all speeds. In a modification of this arrangement (Fig. 7, not shown) the two coils and the rotor are disposed in line along the axis of the motor. In a final arrangement (Figs. 9 and 10, not shown) for A.C. synchronous operation only, the stator is energized solely from a single coil and the triangular pole pieces touch their neighbours at their vertices.

Abstract: 1,137,568. Metal oxide microspheres. UNITED STATES ATOMIC ENERGY COMMISSION. 26 Sept., 1966 [23 Oct., 1965], No. 42763/66. Heading C1A. [Also in Division G6] Metal oxide gel microspheres are prepared from metal oxide sols by injecting a stream of the sol through one or more orifices into a stream of organic drying liquid at an angle to the direction thereof, whilst establishing a velocity gradient in the drying liquid adjacent to the one or more orifices, whereby the sol stream is sheared into drops which then congeal. The sol may be of urania, thoria, plutonia, zirconia, or mixtures thereof. The organic drying liquid may be 2-ethyl-hexanol or 2-methyl-pentanol, and optionally contains a surfactant which may be the tertiary amine " Ethomeen S/15 " (Registered Trade Mark), e.g. in 0À1-0À5 vol. per cent concentration. The gel microsphere products may be dried and calcined, e.g. at 1150‹ C. An apparatus for the above process comprises tapered column 1 with enlarged sections 2 and 3, sol dispersal head 30 (Figs. 2 and 3 illustrating preferred embodiments of this), and organic drying liquid inlets 4 and 5 which inject the liquid tangentially and radially (respectively) into the column. Product microspheres are collected in chamber 8, and liquid effluent from column 1 exits via line 7 and is recycled. In the Fig. 2 embodiment, the sol dispersing head comprises shaft 21 and housing 20 which dips into the drying liquid. The whole is rotated and sol ejected through radial orifices 22, 22<SP>1</SP> ... &c. In the Fig. 3 embodiment, the head comprises inner tube 23 for the sol and outer tube 24 for a stream of drying liquid (from line 10 in Fig. 1) the flow of which is less than the flow introduced at the foot of the column, so that there is a net upward flow in the main part of the column. The sol passes through radial orifices 26, 26<SP>1</SP> . . . immediately above the terminal end of tube 23 into the stream of drying liquid in annulus 28 and thence into the column. Sol injection orifices of 0À01-0À06 inch diameter may lead to microspheres which after calcination are of 150-700 microns diameter.
