Title: Reduction of ores and ore concentrates using a plasma arc
IPC: C22B4/00
Filed: 1968-12-23
Granted: 1971-06-07
Abstract: Apparatus for the carbothermic reduction of ores and ore concentrates in which an ore anode is volatilised by the action of a high intensity arc placed between the anode and cathode. The cathode is an electrode which is part of a plasma generator of the axial type obliquely disposed to the axis of the anode and which includes a tuyere to stabilise the electric arc. The non-consumable cathode greatly increases the capacity of the apparatus and also increases the volatilisation of the anode.

Abstract: 1,050,615. Positive and ratchet clutches. S.S.S. PATENTS Ltd. May 10, 1965 [May 22, 1964], No. 21320/64. Heading F2C. In a Legge type clutch comprising rotary clutch parts 1, 11 each carrying a respective intermediate member 4, 14 helically splined thereto, upon relative turning movement of the parts 1, 11 in one sense, ratchet means 9, 18 operate on the members 4, 14 to effect interengagement of clutch teeth 8, 17 thereon. With the clutch disengaged as shown for twoway freedom, relative rotation of the shaft 11 in the arrowed direction with respect to the shaft 1 causes spring-urged pivoted pawls 18 on the member 14, which is of lower inertia than the member 4, to engage the clutch teeth 8 on the latter, and the member 14 is drawn helically leftwards to a stop 15 bringing the clutch teeth 8, 17 into engagement, the member 4 then being drawn helically rightwards to a stop 6 so that the clutch teeth 17 ratchet over the pawls 9 on the member 4. To bring in one-way clutch action, a control sleeve 22<SP>1</SP>, straight-splined to the member 14, is resiliently urged leftward to engage dogs 23<SP>1</SP>, 24<SP>1</SP>, locking the member 14 to the shaft 11. Subsequent reversal of the relative rotation of the shafts causes the pawls 9 to engage the clutch teeth 17, moving the member 4 helically leftwards to a stop 5, the clutch teeth 8, 17 then being intermeshed. If a sleeve 22, straight-splined to the member 4, is then resiliently urged rightwards, dogs 23, 24 engage to lock the member 4 to the shaft 1, the clutch then being locked for twoway torque transmission. A one-way clutch disengageable for two-way freedom (Figs. 2-5, not shown) utilizes a single control sleeve 52 to lock an intermediate member 44 to a shaft 41, the other intermediate member 35 being helically splined within a hollow cylindrical end 32 of a shaft 31. Oil is supplied centrifugally to an annular cavity between the cylindrical end 32 and the member 35 to cushion clutch engaging movements of the latter. Engagement of dogs 54 of the sleeve 52 with dogs 51 of the shaft 41 is baulked unless the member 44 is in the correct position against a stop 45 for one-way clutch action. A modification (Fig. 6, not shown) dispenses with the control sleeve, and an intermediate member 63 helically splined within a cylindrical end 61 of a shaft 60 has internal ratchet teeth 67, in addition to clutch teeth 66, engageable by pawls 75 of an intermediate member 71 helically splined on a shaft 73. Two-way freedom cannot be obtained in this modification.

Abstract: 1,226,101. Lathes, swashplate motors. NATIONAL RESEARCH DEVELOPMENT CORP. 15 March, 1968 [28 March, 1967], No. 14110/67. Headings B3B and B3T. A machine tool comprises a rotary work chuck 47, mounted on a spindle 45, carried in a carriage 33, transversely movable across the diameter of a cylinder 13 which is rotatable in a housing 5, axially slidable in a casing 1. Housing 5 is movable in the casing by double-acting pistons 9, and its position and velocity is monitored by a linear transducer scanned by a pick-up head. Cylinder 13 is rotated by a motor 15, which drives a spur gear 19, meshing with a gear ring 21 on the housing 5. The angular orientation and rate of movement of housing 5 is monitored by an optical grating 23, which co-operates with a reading head 25. Carriage 33 is adapted to be moved across the diameter of cylinder 13 on a slideway 65, by double-acting pistons 37, and its position is monitored by an optical grating 67 which co-operates with a reading head 69. Spindle 45 is rotatable by a swash plate motor 57, or multilobe ball motor 60. The position and velocity of spindle 45 is monitored by a rotary transducer and reading head. Six tool holders 70 are disposed at different angular orientations around the axis of cylinder 13, four of which are turning tools, one is a milling attachment, and one is a drilling attachment. In operation, motor 15 rotates cylinder 13 to align the diametrical axis of the cylinder with the tool to be used, as indicated by head 25. Cylinders 7 displace housing 5 axially and motor 57 or motor 60 is used to rotate the workpiece 71. Cylinders 37 are actuated so as to move the workpiece radially towards the selected tool. By controlling carriage 33 and housing 5 in a continuous manner, the workpiece centre can be constrained to describe chordal movement. During chordal traversing a further axis has to be brought into operation to offset the induced rotational movement of the workpiece, and this is achieved by controlling the ball motor incorporated in the headstock drive. The three control movements may be used in a numerical or continuous path control. The linear and rotary transducer may be replaced by transducers of the Inductosyn or Helixyn (Registered Trade Marks) mode of operation.

Abstract: 1,238,475. Transferring articles between endless conveyers. SCHWEIZERISCHE INDUSTRIE-GES. 20 Nov., 1968 [20 Nov., 1967], No. 54960/68. Heading B8A. A device for lining up objects A, such as individual packages or boxes, that are carried irregularly spaced in two or more rows on at least one first conveyer 1, comprises a collecting table 2 for receiving the objects advanced by the first conveyer; a pusher 5 for moving from a starting position (shown) to push the objects in groups from said table to a second conveyer 11; and an individual line-up feeler 3, 4, for each row of objects, and positioned to be operated by the leading object of a respective row for controlling the operation of the pusher to cause the latter to execute a stroke only when an object has operated at least one of the line-up feelers 3, 4. As shown in Fig. 5, there is a separate intermediate conveyer 15 respective to each row of objects A on the conveyer 1. A respective brake 8 is provided at the downstream end of each conveyer 15 to hold the leading object A of the row against conveyer movement. A respective coupling 12 is disposed between the drive-motor of each conveyer 15 and the conveyer drive shaft and is controlled by an operating device 12A. Feelers 9 respective to each conveyer 15 are arranged to operate a switch 9C on the passage of an object A. Due to the action of a time comparator circuit 9C the switch 9C is only allowed to be effective in releasing the brake; if there is a row of objects A backed up between the respective brake 8 and the feeler 9. A further time comparator circuit 14 provides a time delay in the operation of the coupling operator 12A. A switch 10 operated by the pusher 5 in its retracted position, prevents release of either of the brakes 8 when the pusher is not retracted. When the pusher has completed its transfer stroke it operates a switch 16. This initiates the retraction of the pusher and initiates operation of each coupling operator 12A. In a further modification (Fig. 4, not shown) the switch 16 is dispensed with. In yet another modification (Fig. 3, not shown), the intermediate conveyers are dispensed with, the brakes 8 being provided at the downstream end of the conveyer 1 (which feeds directly to the table 2 as in Fig. 1).
