Title: Improvements in or relating to materials containing ores and coke
IPC: C22B1/14
Filed: 1966-08-09
Abstract: Ore-coke pellets of high strength and containing reduced matter are manufactured by pelletizing under sprays of water finely divided ore mixed with coking coal, coking the green pellets formed in a finely divided heat carrier and finally cooling them.  Minor amounts of bitumen or pitch or an inorganic binding agent such as bentonite may be added to the mixture, to increase the strength of the green pellets, which may be dried out at 500 DEG  to 700 DEG  C. in a heat carrier, before coking.  The heat carrier may be preheated to 1000 DEG  to 1400 DEG  C. for coking.  Coals with a volatile content between 17 and 40% and a swelling index between 1 and 9 are most suitable, and may be added slightly in excess of the stoichiometric amount required to reduce the ore. All finely-divided ores and ore concentrates are suitable as the initial ore.

Title: Improvements in or relating to a Control Device for a Tool-Carrying Carriage of a Copying Lathe
IPC: B23Q35/18
Filed: 1967-08-10
Abstract: 1,165,817. Copying lathes. CENTRE DE RECHERCHES DE PONT-A-MOUSSON. 10 Aug., 1967 [24 Aug., 1966; 17 July, 1967], No. 36685/67. Heading B3T. An hydraulic copying lathe has a saddle 2, a transverse carriage 3 and mounted thereon a tool slide 4 which is arranged to be fed by a cylinder and piston V under the control of a needle valve A. At the commencement of operations the core 6 of an electromagnet E is in a fully extended position and bears against a lever L 2  which holds the valve needle 10 in a valve-closing position, the tool slide 4 therefore being retracted from the workpiece. Upon closing of a starting switch the electromagnet E is energized withdrawing the core 6 thereby allowing the lever L 2  to pivot under the action of a spring 11 till it engages a rod D which bears against one of a set of detachable gauge rods F the length of which determines the depth of the respective roughing cut. When no gauge rod is presented to the rod D the lever L 2  pivots further until it engages a pin 8 on the end of a further lever L 1  which is rigidly connected through a pivot pin 7 to the copying lever 7a and tracer C; the device is then ready for the finishing cut with the tracer C following the template B. During the roughing cuts when the tracer C engages a shoulder 33a of the template B the lever L 1  is pivoted and opens a microswitch 9 which de-energizes the electromagnet E with consequent closure of the valve A through the action of core 6 on lever L2, thereby retracting the tool slide from the workpiece. In a modification, Fig. 8, a rod T is included which serves to limit the return movement of the slide 4. The rod T has a head 36 engageable with the lever L 2 , and an adjustable collar 37 engageable with a fixed abutment 38. Thus at a certain point in the return movement of slide 4 the head bears on the lever L 2  in opposition to the core 6 of electromagnet E to open the valve A and arrest the slide 4. Also carried on the rod T is a sector S of varying thickness which serves according to its position angularly to regulate the degree of lost motion between the levers L 1 , L 2 , thereby providing for a semi-finishing cut of adjustable depth of cut with the tracer C following the template B. Rotation of the rod T positions the sector S angularly at the point of the required thickness and is effected by a lever 42 and cam device 45. A microswitch, not shown, determines the limit of travel of the saddle 2 longitudinally of the workpiece and thus the length of the finishing cut.

Abstract: 971,394. Change-speed controls. VAUXHALL MOTORS Ltd. Sept. 26, 1963 [Sept. 28, 1962], No. 36872/62. Heading F2D. A change-speed lever 18, ball-mounted for movement in two planes at right angles to each other, is formed at its depending end with two unequal length legs 20, 22 which straddle a crank-pin 8 having flanges 10, 12 abutted by convex bearing surfaces 24 at the sides of the legs, the crank-pin &c. being mounted by an eccentric stud in an arm 6 fast upon the end of a selector rod 2. Pivoting the change-speed lever 18 anti-clockwise of Fig. 2 brings the end of the longer leg 20 up against the selector rod 2, and thus prevents the inadvertent establishment of reverse. To select reverse, the change-speed lever 18 is pulled upwards against spring bias and the pivoted, when the end of the longer leg 20 clears a flat 5 on the selector rod 2, the corresponding turning of the selector rod actuating a striker fork. The crank-pin 8 is secured to the arm 6 by a nut 13, which is loosened to permit rotation of the pin and its eccentric stud for adjustment. The selector rod 2 may control a change-speed gear having one or several striker rails. Specifications 935,501 and 971,395 are referred to.

W.; 14, Ralston Avenue, Whitneyville, Hamden, Connecticut, U.S.A.) Dec. 4, 1930, No. 36655. Convention date, Dec. 13, 1929. [Class 109.] Fine conductors such as those used for magnet wire are insulated with a compacted mass of fibrous insulating material in which the fibres near the conductor are parallel with it and the fibres at the outer surface of the insulation are circumferentially arranged. A reinforcing filament is embedded in the fibrous mass. In the construction of apparatus for insulating a wire shown, a sliver 13 of asbestos fibres are delivered on a travelling belt 15 by a comb 14 from the doffer roll 12 of a carding machine. The sliver 13 is laid on a thread 16 moving with the belt and unwound from a roll 17. The sliver 13 and thread 16 are fed between rub-motion belts 18, 19 which cause the fibres to wrap round the thread 16. The thread-reinforced sliver 20 is wound on a reel 21. The sliver 20 is fed over a guide roller 22, Fig. 2, to a conductor 23 which is fed downwardly from a guide roller 24 and reel 25. Between the reel 25 and roller 24 the conductor 23 passes through an adhesive bath 26. The sliver coated conductor passes into a rapidly rotating wiper 27 which may comprise opposed resilient fingers 28, 29, Fig. 3, mounted on a spindle 30 to which a pinion 31 is secured. The pinion 31 rotates the wiper 27 from a drive shaft 33 causing the fingers 28, 29 to revolve about the sliver 20 so that the sliver completely surrounds the conductor 23. The conductor passes through a bath of insulating compound 35 to a wiper 36 which is rotated from the shaft 33. Resilient fingers 40 on the wiper 36 press out surplus compound from the conductor insulation. The wipers 27, 36 both rotate in the same sense. The conductor is fed between opposed polishing plates 41, 42 of a device 43. The plates 41, 42 are slidably mounted in a frame 44 and are guided by stems 45, 46 disposed in openings 47, 48 in the frame 44, Fig. 4. Links 49, 50 attached to each stem 45, 46 are secured to plungers 51, 52 slidably mounted for transverse movement relative to the conductor. The frame 44 is rotated with the wiper spindle, centrifugal force moving the plungers 51, 52 outwardly to pull the plates 41, 42 against the conductor. Specification 367,943 is referred to.
