Title: Extracting potassium sulphate
IPC: C01D5/10
Filed: 1962-11-19
Abstract: <PICT:0979325/C1/1> Potassium sulphate is extracted from minerals or mixtures containing ions of potassium, magnesium, and at least one of chloride and sulphate, in three stages: (a) leaching a mineral or mixture of the above-mentioned kind in the presence of sulphate ions and artificial carnallite recycled from the third stage in countercurrent with water at from 10 DEG  C. to 40 DEG  C. so as to obtain solid potassium sulphate and residual mother liquor; (b) reacting a mineral or mixture of the above-mentioned kind, which must contain chloride ions if that used in the first operation does not, with magnesium chloridecontaining mother liquor recycled from the third operation, which is concentrated before, during or after the reaction, and also with the residual mother liquor from the first stage at from 100 DEG  C. to 130 DEG  C. so that solid kieserite and halite separates; and (c) cooling the mother liquor from the second stage to form 30 DEG  C. to 60 DEG  C. so as to obtain artificial carnallite for recycling to the first stage and also to obtain magnesium chloride-containing mother liquor for recycling to the second operation.  The first stage is preferably carried out so as to minimize the amount of water used and the potassium content of the mother liquor obtained, and the water used may be replaced, up to 70 to 80%, by sea water.  The mineral salt treated in the first stage may be partially or totally replaced by purified kieserite residue obtained in the second operation.  Mother liquors may be withdrawn from the end and from the middle of the first countercurrent operation in order to minimize sodium impurities in the potassium sulphate by mixing the liquors and then conveying to the second operation.  The recycled artificial carnallite obtained in the third operation may be purified from sodium chloride prior to being recycled to the first operation.  Any excess recycled carnallite may be leached with water to produce potassium chloride.  The magnesium chloride-containing mother liquor may be further processed to obtain magnesium chloride (30 to 35% solution), and also magnesium oxide, metallic magnesium and chlorine. Fig. 1 shows the overall scheme of the process.

Filed: 1974-10-11
Abstract: 1470417 Distilling zinc ISC SMELTING Ltd 12 Sept 1975 [11 Oct 1974] 44066/74 Heading C7D Zinc vapour is condensed in a multi-stage condenser in each stage of which the vapour is contacted with a spray of molten lead produced by a rotary impeller immersed in a pool of molten lead and the temperature of the molten lead in an intermediate stage is maintained in the range 475-515C. In the apparatus shown zinccontaining vapour is passed from inlet 1 to outlet 2 of a three-stage condenser whose first stage has impellers A and B while impellers C and D provide the second and third stage respectively. Molten lead passes in countercurrent to the gas and is recirculated through a cooled launder 4 to form a two phase melt, the upper zinc layer being separated at 5. Temperature control at the intermediate stage may be effected by heating the said intermediate stage, by returning some of the hot lead leaving the condenser directly to the intermediate stage through duct 9, or by feeding some of the cooled lead after it has left separator 5 direct to the first stage through duct 10. In this last method the reduced flow of lead through the intermediate stage causes an increase of temperature at that stage. In a further embodiment Figs. 2-5 (not shown) a part of the lead spray in the first condensation stage is caught in ducts (15) sloping down towards an aperture (14) in baffle 7 and the lead so caught is returned to the intermediate stage directly through the said aperture.

Abstract: 1494054 Transistor amplifier SONY CORP 28 Oct 1975 [31 Oct 1974] 44409/75 Heading H3T In a transistor amplifier with complementary FETs 20a, 20b in a single-ended push-pull output stage 3 feeding load 6, preferably in class AB or B, and driven by transistors or equivalent devices 18a, 18b in drive stage 2, any risk of excessive gate leakage current, particularly during the non- conducting half cycles of the FET's, is avoided by providing constant current circuits 23a, 23b as emitter loads. The complementory FET's in a common drain mode have gates directly connected to the emitters of transistors 18a, 18b which may in turn be fed by an NPN differential transistor amplifier 8, itself driven from the input via preamplifier 7, and equipped with a current mirror circuit 14, 15, 16, 17 to maintain equal currents through resistors 12, 13, the oppositely phased feeds being taken off across resistor 13. In the two constant current circuits 23 the drop across the two diodes 28, 29 is balanced against the base-emitter drop of transistor 24 plus the drop in resistor 25, in each case. In an alternative embodiment (Fig. 5, not shown) the FET's feed the load in common source mode and are themselves fed by the drive stage transistors 18a, 18b with constant current emitter circuits as above connected between the  B 2  supply lines, the FET's and pre-amplifier being on  B 1  supply, both supplies being preferably balanced about ground and stabilized. B 2  is made greater than B 1  to avoid any risk of excessive voltages appearing on the FET's. Transistors 18a, 18b are now fed from PNP differential transistor amplifier, A.C. coupled to the input terminal and having a constant current circuit as common emitter load, via two further amplification stages. The extra amplification allows both the differential amplifier and the centre point of the stage directly feeding transistors 18a, 18b to be coupled to a negative feedback line from point 5 on load 6. The D.C. voltage difference between the FET gates and the bias on transistors 18a, 18b are adjustable together by a variable resistor. Single sided versions of the circuits are also included in the invention. A triode-like FET (Figs. 2, 3, 4) is preferable in the output stage of each embodiment.

Abstract: 1,072,732. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 18, 1964 [June 21, 1963], No. 44487/66. Divided out of 1,072,731. Heading B7K. In an air cushion vehicle, a cushion-containing flexiblewall 5 comprises a first stage in the form of an inflatable bag 7 and a second stage 8 formed by a series of separate channel-shaped sections of flexible material attached to the first stage. Ducts 10, 12 extend from a compressor 11 which supplies air for a curtain 6. A further compressor 14 supplies air through duct 13 to inflate bag 7, which may be drawn upwardly against inflation pressure by a plurality of cords 15 connected to jacks 19. The jacks 19 may be actuated in response to deviations of attitude of the vehicle, but in the embodiment actuation is responsive to pressure changes in ducts 12 detected by pressure heads 21, 22 which connect through chambers 26, 27 to opposite sides of a capsule 33 which actuates valves 35, 36 controlling the operation of jacks 19. A trimming mechanism may override the automatic control mechanism. An arrangement of pressure heads 40 in the base of the vehicle may be used to detect deviation in pitch and roll. In operation, should the vehicle tilt, the increase in pressure at the lowered portion of the periphery will be sensed to cause-operation of the appropriate jacks 19 to enable the inflatable bag to extend downwardly thereby locally increasing the pressure to tilt the vehicle level. Reference has been directed by the Comptroller to the Specification 935,825.

Abstract: 1368190 Semi-conductor devices SONY CORP 28 Sept 1972 [30 Sept 1971] 44882/72 Heading H1K A pair of complementary vertical transistors are formed in an integrated circuit by dividing a pair of opposite conductivity type epitaxial layers on a substrate of the opposite type to the lower layer into device areas by means of concentric isolating rings extending through the individual epitaxial layers and utilizing the two epitaxial layers and a diffused emitter region as a transistor in one isolated device area and the upper epitaxial layer and diffused base and emitter regions as a complementary transistor in another device area. As shown, an N type Si substrate 1 is provided with a first epitaxial layer 2 comprising a P+ type portion 2A and a P type portion 2B. An SiO 2  layer (5) is used as a mask for the diffusion of P to form N + type isolating rings 4, in the form of a chain, through the epitaxial layer 2 and a diffusion of As is used to produce an N + type buried layer 6 in one of the isolated regions. The SiO 2  layer is removed, and N type epitaxial layer 7 is deposited and individual P+ type isolating rings 9A, 9B, 9B concentric with rings 4 are diffused through the layer 7 using a second SiO 2  masking layer 11. An NPN transistor 10 is formed in the isolated area containing the buried layer 6 by diffusing- in a P type base region 10b and N + type emitter and collector contact regions 10e, 10c<SP>1</SP>. The part 10c of the top epitaxial layer 7 forms the collector region. A PNP transistor 12 is formed in a second isolated area by diffusing-in a P type emitter region 12e and an N+ type base contact region 12b<SP>1</SP>. The parts 12b and 12c of the two epitaxial layers form the base and collector regions respectively and the collector region is contacted via the P+ type isolating ring 9B. A JUGFET 14 is formed in a further isolated area by diffusing-in a P type upper gate 13g 2  and N + type source and drain regions 15s, 15d. The isolated part of the top epitaxial layer forms the channel region and the part 13g 1  of the lower epitaxial layer forms the lower gate region to which contact is made via the P + type isolating ring 9C. The P type regions 10b, 12e and 13g 2  may be formed simultaneously as can the N+ type regions 10e, 10c<SP>1</SP>, 15s and 15d. Electrodes are applied by vapour deposition and photo-etching. The lower face of the wafer is mechanically or chemically planed down and an electrode 19 is deposited which in use is connected to the highest fixed potential of the circuit to ensure that the isolating junctions are reverse biased.
