Abstract: 1,228,871. Refining metals. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 16, 1968 [May 19, 1967; Dec.12, 1967], Nos.23311/67 and 56383/67. Addition to 1,187, 972. Heading C7D. A process for refining metal comprises shattering a stream of molten metal freely falling within a reaction chamber of a stream of gas which reacts with the impurity to be removed, extracting gas through offtake ducting thereby inducing flow of further gas into the chamber, and controlling the flow of that further gas into the chamber in accordance with a condition obtaining in a zone defined by the chamber and off-take ducting. As shown in Fig. 1 molten metal flows from the outlet 4 of tundish 3 into a reaction chamber formed by hood 6 and receptacle 7, in which it is shattered and reacted with gas from gas discharge duct 9. The waste gases are discharged through duct 13. A ring 14 suspended by chains or ropes 15 surrounds the gap 11 between the hood and receptacle and its position is adjusted manually or automatically to control the rate of flow of induced air. Control may be in response to the gas analysis or gas pressure in the exhaust ducting or in response to the slag level in the receptacle. Alternatively as shown in Fig.2, the design of the hood and receptacle in the region of the gap and of the surrounding ring 21 may allow control of the direction of flow of induced air to give a current of cooling air over the inner surfaces of the hood. In a further modification, instead of using a ring the depth of the gap 11 in Fig.1 may be varied.

Abstract: 1,232,599. Golf practice device. J. CURRY. 12 Nov., 1968, No. 53479/68. Heading A6D. A golf practice device consists of a base A having an upstanding post B with a threaded portion I and having articulated legs C extending radially outward; a swivel arm D rotatable about the post B with a simulated golf ball E attached to its outer end; and a vertical yardage-indicating scale M attached to the arm D carrying a slidable indicator N with a projection 34 having a threaded connection with the threaded portion 1. The hollow sleeve M is of rectangular cross-section and has a longitudinal slit in the face 30 with a scale in yards marked thereon. The slidable indicator N fits closely inside the sleeve M, so that when the arm D rotates due to the ball E being struck the indicator N rises vertically owing to the threaded connection between the concave portion 34 and the portion 1 of the post B. The arm D is prevented from riding up the post B by a metal keeper or key F inserted in an annular groove 2. The simulated golf ball E is hollow and is approximately the size of a half sphere of a standard ball. The ball E is attached to the arm D by a resilient member K shaped as a "lazy-S" to absorb some of the impact. "Hook" and "slice" indicator: The ball E has resilient rubber inserts G1 and H1 mounted in its wall with sockets 21 containing electric terminals 22, the sockets having narrow necks opening on to the inner surface of the ball. The sockets have associated flexible electrodes G2 and H2 with one end anchored in the wall and heads 20 receivable in the sockets 21, such that when the ball E is struck near either rubber insert the associated electrode head is forced into the socket and completes a circuit which connects a source of current to an indicator light G or H mounted on the arm D, G indicating "hook" and H "slice". If the ball E is struck centrally between the inserts G1 and H1 both lights are illuminated. The current source is provided by batteries in a compartment in the arm D covered by a sliding door J. The electrodes are ejected manually from the sockets by pressing the outer ends of the rubber inserts. Dis-assembly and storage: The extension 33 of the indicator N is slightly flexible so that it may be moved away from the post B thereby disengaging the threads, and after removal of the key F the arm D may be lifted off the post B. A pivot 28 is provided so that the sleeve M may be swung into alignment with the arm D. The legs C are pivoted at their point of attachment to the base A and jointed at their centrepoints, and may be folded in half and swung into alignment with the post B, thus facilitating storage.
