Abstract: 1487856 Upgrading ilmenite ore MITSUBISHI KINZOKU KK 20 Nov 1974 [20 Nov 1973] 50189/74 Heading ClN Ilmenite ore is upgraded by oxidation roasting the ore, chlorinating the oxidized ore in the presence of a solid carbonaceous material whereby the larger part of the iron values are selectively chlorinated and evaporated and subjecting the chlorinated ore to magnetic separation in a high density magnetic field of at least 15,000 gauss. The non-magnetic portion may be subjected to froth flotation using a collector for sulphite ore so as to separate the residue of the solid carbonaceous material and a gangue value partially liberated from the ore in the chlorination and to obtain a rutile of high TiO 2  content as a tailing portion. The frothing agent, e.g. methylisobutyl carbinol, pine oil or ethylene glycol and the sulphide ore collector, e.g. a xanthate or a dithiophosphate are preferably both used in quantity of 10-500 g./ton of the non-magnetic portion. The tailing portion from the flotation may be subjected to a scavenging operating with an alkylamine derivative and/or kerosene to effect a better separation of the carbonaceous residues. The magnetic portion may be recycled to the chlorination stage, which suitably comprises the chlorination of a preoxidized ore with 6-8% of a solid carbonaceous material, e.g. calcined petroleum coke in a fluidized bed furnace.

Abstract: 1492210 Screw conveyers BIRD MACHINE CO Inc 8 Dec 1975 [16 Dec 1974] 50244/75 Heading B8A [Also in Divisions B1-B2] A hard-surfaced solids-discharge screw conveyer for a solid or perforate bowl of a centrifuge comprises a helical metal blade 32 on one of the radially disposed side surfaces of which is mounted a plurality of wear-resisting segments 34, mating parts 50 and 36 on the opposed surfaces of the segments and blade respectively being slidably interengaged by sliding the segments generally radially outwardly of the blade surface to prevent radial outward and axial relative movements of the blade and segments. The parts 36 are constituted by wedge-shaped metal pieces which are plug-welded as at 40 to the blade 32 to define dovetail slots which are wider at their radially inner ends. The segments 34 are formed of moulded ceramic material and their parts 50 consist of underside wedgeshaped projections which engage tightly in the slots between the metal pieces 36 under centrifugal force when the screw conveyer is rotating. The parts of adjacent segments forwardly of the projections 50 are of different shapes. Thus the right-hand segment in Fig. 4 has radially inwardly converging sides and the left-hand segment have parallel sides, so that the sides of adjacent segments abut when mounted. Pins 54 are welded to the blade 32 in abutting relation with the radially inner ends of the segments to prevent them from sliding out when rotation of the screw conveyer is discontinued. When wear necessitates replacement of a segment its associated pin is first clipped off and the segment is tapped radially inwardly until it slides out from between adjacent segments.

The dispenser comprises a moulding enclosing an electromagnet 1, 2, whose core 5 is integral with a non-magnetic rod 6 carrying a square or polygonal 8 and 7 which is biased by a spring 8 and slides in a similarly shaped space in a moulded cover 9. A pin 11 on the lower end of rod 6 engages a slot in the main moulding to hold the cover closed when the door of a washing machine is opened so that the device is horizontal, detergent is placed in tank 4 and cover 9 is closed by rotation, until the springs 13 are tensioned and pin 11 engages slot 12. An electric impulse to the electromagnet releases pin 11 from slot 12 and hence cover 9 rotates to release detergent into the machine. In a front opening dish-washer the dispenser is secured liquid tight in an opening in the inner wall 22 of the door by its edge 18. It comprises a moulded synthetic resin or metal cup-shaped housing 51 with a semi-circular cover 52 and the same number of cavities surrounding a core 53 as there are wash cycles, e.g. two as shown. Cover 52 engages bearing surfaces 31 on core 56 and 32 on the lip 18. The ends of the coil 57 of solenoid 20 are enclosed by the legs 24 of a U-shaped ferromagnetic pole member 58, and the whole is moulded into the base of core 56. Within coil 57 is a movable armature 59 and passing through its centre shaft 60, whose upper end is moulded into a cap 61, with a square head 37 and whose lower end 34 is enlarged and passes through bushing 26. Head 37 is biased upwardly by spring 63 into a square hole in cover 52. Core 56 and cap 61 are connected by a torsion spring 64. A pin 66 secured to the end 34 of shaft 60 engages a shoulder 46 on the housing when the cover is over the second cavity 55. In operation, the cover is rotated until it overlies the filled cavity 55 with pin 66 engaging shoulder 46 and biased by spring 63 and then cavity 54 is filled. When door 30 is closed detergent in cavity 54 is dispensed and, on completion of the first cycle, coil 57 will be activated to release pin 60 from shoulder 46 when spring 64 will rotate the cover 52 clockwise and expose cavity 55 to deposit the second charge of detergent. In a modification, pin 66 engages a lip 41 until the solenoid is actuated when it is released and slides round to lip 42, Fig. 10.
