Title: Improvements in processes for obtaining artificial magnetic oxides for dense liquors
IPC: B03B1/02
Filed: 1961-11-13
Abstract: A "dense liquor" suitable for the sink and float enrichment of ores consists of an aqueous suspension of ferromagnetic oxides. These are prepared by subjecting a non-magnetic iron oxide ore to a first magnetizing roasting in suitable temperature and reduction ratio conditions as given by the Chaudron diagram, in order to reduce all the iron oxides to ferromagnetic oxides this first treatment being followed by a treatment proper of the ore at at least incipient or partial fusion temperature, but below the melting points of the impurities, in a reducing atmosphere of CO/CO2 with a reduction ratio by volume at least 0.85.  The second reduction is carried out in the presence of water vapour, in order to prevent over-reduction of the oxides.  The temperature of the second stage is preferably between 1250 DEG  and 1450 DEG  C. The calcined product is suspended in water and subjected to wet magnetic separation to yield a dense aqueous concentrate of ferromagnetic oxide. Specification 960,725 is referred to.

Title: Improvements in means for orienting valve bases and similar components
Inventor: MCPHERSON ALEXANDER
IPC: H01J9/24
Filed: 1959-12-07
Abstract: 894,397. Orientating valve bases; conveyers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 2,1960 [Dec. 7, 1959], No. 41521/59. Class 78 (1). A device for feeding and orientating electronic valve bases and similar components comprises a horizontal trough-shaped member 4 having a floor 1 and wall 2 which are smooth, and a serrated wall 3. As shown in Fig. 1, valve bases A are moved in the direction of the arrow by means such as a blast of air or a moving belt (not shown) running along the floor 1. The width a of the trough just gives free clearance to the valve bases which when they reach the serrated wall section 3 the pins engage the notches of the serrations and the bases rotate as they move along the trough in cycloidal fashion. Figs. 5, 6 show the last portion of the cycloidal motion when pin I is released from the notch 15, the pins I, IX are in line against the plain edge of a guide portion 16, and a blade 5, urged by springs 6, moves laterally to mask the notches of the wall 3. The Figures show the case when pin IX of a base engages the first notch 7 under the blade 5. In all other cases the base is correctly orientated before reaching the last notch 15. To avoid jamming due to one or more bases moving into the masked section of the serrations before other bases have passed out, the mask blade may be divided into a number of sections actuated by leaf springs. The bases may travel with the pins pointing upwards, the moulded part of the base resting on the edges of a slot (not shown) in the floor 1 with any connections to the pins hanging downwards. Alternatively, the bases may travel along the trough with the pins resting on the floor. In place of the compressed air blast or moving belt for conveying the bases, a reciprocating claw may draw the bases along the trough. As shown in Fig. 4, a lever 26 is pivotally supported in a bracket 23 slotted at 28 to define the angle through which a crank arm 24 of the lever 26 moves. The bracket is slidable longitudinally of the trough, is guided by pins 22 in a slot 21 and is frictionally braked by a spring 30. When a connecting rod 29 moves to the right, the lower part of the arm 24 moves to the limit of its travel in the slot 28 before the bracket 23 begins to move. The lever 26 is thus lifted out of the trough before moving along and, on the return stroke, is first lowered before the bracket moves backwards. A pin 27 engages loosely in the centre hole in the valve base. In a further form of trough, Figs. 7, 8, a guide member 35 engages the pins of the base instead of the annular edge. Plate-like pawls 37-39, biased by springs 40-42, act as masking members.

The stock stop has an arm 20 pivotally mounted in a carrier 18 which displaceably mounted on a slideway 17 secured to the cover tube 13. The drum shaft and cover tube extend across the machining area of the lathe between a gear-box 50 and the spindle drum 11 the shaft and tube each being relatively rotatable with respect to each other. The cover tube is supported in a mounting 14 at the gear-box end on which is located a curved lever 41 with a roller 42 which engages with an annular cam member 46 secured to the drum shaft 10, the roller 42 being guided in a cam track 47. The lever is pivoted at one end 40 to the housing 14 and the other end engages in a slotted member 44 attached to the cover tube whereby rotary indexing of the drum shaft effects angular displacing of the cover tube due to engagement between the cam and roller and which pivots the stop stock between an operative position in which the stop abutment is in alignment with the stock which determines in axial position in the spindle at the loading station, and an inoperative position which is out of alignment with the spindle indexed position. The stop stock is adjustable longitudinally of the cover tube by way of slots 28 which are engageable by way of the threaded member 26 to effect fine adjustment, the stop carrier 18 being clamped to the slideway 17 by way of screws 19.
