Patent GB-901515-A (GB)
Title: Improved froth flotation method
Inventor: GREENE ERNEST WILFRID
IPC: B03D1/001
Filed: 1961-01-23
Abstract: A very finely-divided multicomponent mineral mass is beneficiated by a method which includes the steps of forming an aqueous pulp of the mass in which at least one of its components is selectively oiled and which contains in intimate association with the mass collector-coated auxiliary mineral particles which are flotable in the presence of the aqueous pulp and subjecting the conditioned aqueous pulp to froth flotation.  The multicomponent mineral mass and the auxiliary mineral can be treated concurrently, as an aqueous pulp with a collector reagent which selectively oils certain components of the mineral mass and the particles of the auxiliary mineral, or they may be treated separately, each in the form of a dispersed aqueous pulp which are then admixed.  The component of the mineral mass which is not selectively oiled is water-wettable and becomes a machine discharge product.  The materials may also be reagentized as they are being ground to a grain size suitable for flotation.  Any mineral capable of being provided with an orientated hydrophilic surface coating may be used as an auxiliary, the coating being of a character such that the auxiliary mineral will be flotable in the presence of the particular reagentized feed pulp.  Suitable auxiliary minerals are calcite, barytes, kyanite, silica sand, anatase and flurospar. Suitable reagents for floating the auxiliary minerals are known or may be found by experiment.  The auxiliary mineral may be separated from the floated fraction, if required, by known means.  The main application of the invention is to the beneficiation of kaolin clay discoloured with titaniferous and ferruginous matter.  In one embodiment, an aqueous pulp is formed of kaolin and sodium silicate solution and these are added, as reagents: ammonium sulphate, ammonium hydroxide, crude tall oil fatty acid, neutral calcium petronate and a water-soluble petroleum sulphonate.  An aqueous pulp is separately formed of calcite, caustic soda and crude tall oil. The two pulps are admixed and subjected to froth flotation.  Other examples are given of the beneficiation of different types of kaolin, with the multicomponent mass and the auxiliary mineral reagentized concurrently or separately, and the metallurgical results are tabulated with reference, among other data, to the whiteness of the resulting clay in terms of its brightness index according to a known standard referred to.

Title: Control device
IPC: F01N3/22
Filed: 1974-01-21
Abstract: 1439301 Afterburner air supply HITACHI Ltd 21 June 1974 [22 Jan 1973] 02820/74 Heading B1W A secondary air control device in which a pump supplies secondary air to an exhaust gas afterburner at a rate proportional to the exhaust gas flow rate, comprises an air passage 5 connecting the pump 1 to the afterburner 4, a resistor e.g. an orifice 6 in the passage and a control valve 3 for maintaining substantially constant the ratio of the pressures upstream and downstream of the resistor. Valve 3 consists of a valve member 9 which controls an outlet, from a surge tank 2, leading to atmosphere; a diaphragm 12 subject on one side to surge tank pressure and on the other side to atmospheric pressure; and a diaphragm 13 subject on one side to the pressure in the afterburner chamber and on the other side to atmospheric pressure. As the pressure P R  in the afterburner chamber increases, it acts on diaphragm 13 and tends to close valve 9, thus preventing air escaping to atmosphere through outlet 20. During acceleration the rate of supply of air to the afterburner should be increased. This is achieved by an electrical switch operated by a diaphragm responsive to increase in inlet manifold pressure which operates to move valve 21 to the closed position. The surge tank pressure is then no longer applied through passage 18 to diaphragm 12 so that the force acting in opposition to movement of diaphragm 13 is reduced, valve 9 moves towards the closed position and pressure in the surge tank increases. If it is necessary to reduce the secondary air supply e.g. to prevent a catalyst over-heating, a second switch responsive to temperature or the oxygen content of the exhaust gas, operates to close valve 22, thus venting the pressure acting on diaphragm 13 and allowing valve 9 to open and vent the surge tank. In a modified construction the valves 21 and 23 are omitted.

Abstract: 547,891. Making cans. CROWN CORK & SEAL CO. March 13, 1941, No. 3457. Convention date, Jan. 24, 1940. [Classes 83 (ii) and 83 (iv)] The formation of the curls, to receive crown corks, on the necks of containers of the type made by the machine described in Specification 546,489, is effected by a machine having a combined rotary work and die carrier. Pedestals 17, 18, Fig. 1, support a non-rotatable shaft 21 on which is hinged a cam 50. Bearings 37, 38 support a gear 36 provided with pairs of bosses 58 in which are mounted rods 62 that pass also through bosses 60 in a second rotary member 55 tying the members together for simultaneous rotation by a pinion 35 on a shaft 28 driven through a clutch 31 and reduction gearing 25 from a motor 22. On each pair of bars a carriage 65 supporting a mandrel 71 is mounted to slide as controlled by a follower 68 engaging the cam 50. Also mounted on the member 55 is a circular work carrier with pockets. Each pocket receives a cam body from a supply shoot, the body seating at 77, clearance being provided at 78 for the seaming flange 79. A front plate 82 is shaped to suit the neck 84 and a plate 81 acts to strip the body from the mandrel 71 just prior to discharge down a delivery shoot. Journalled at 95 in the member 55 are a series of die carriers 100 having projections 99 received in arcuate slots in 55. Arms 101 carry rollers 102 engaging a fixed external cam track 103 mounted at 104 on the base so that either the preliminary curling die 110 or the closing die 111 may be swung into position in axial alignment with the cam. Further cams 105 carry blocks 106 sliding on pivoted rods 107 so that confined springs 109 keep the roller in engagement with the cam track. The dies are mounted in holders 112 having shanks screwed at 114 into flanged screwed bushes 115 clamped in the projections 99 by nuts and washers 118. In operation after a can body is seated in the pocket the mandrel advances rapidly into the blank then more slowly toward the neck against the curling die after which there is a brief dwell followed by a retraction of blank and mandrel sufficient to permit the die carrier 100 to be rocked to swing the closing die into position. After another advance and dwell a rapid and complete withdrawal follows during which the can is stripped from the mandrel. The next dwell provides for the discharge of the can and the reception of a fresh blank. The front plate 82 is mounted on spring controlled rods to permit the can to move forward with the mandrel during the actual curling and flattening operations and to ensure the return of the can with the mandrel during the short retraction between the two operations. If the preliminary leading of the edge, to prevent splitting, is also then carried out in the machine then the die carriers 100 have three positions and carry three dies, the cam tracks being modified accordingly. Specification 544,040 also is referred to.
