Title: Turning device
Inventor: IGARASHI MAKOTO
IPC: F01D25/34
Filed: 1978-04-05
Abstract: PURPOSE: To secure constant turning by providing a mechanism which prevents disengagement of a driving gear of a turning device and a driven gear of a driven shaft if the driven shaft revolutes higher than the turning device.  
     CONSTITUTION: While the centrifugal force exerted during turning tends to push a rod 66 and compress a compression spring 80, it bearing specified compression force by a spring-force-rated bolt 81 and nut 83 will not be compressed by the force within a recomended range to bring the rod 66 in no motion. As a cranklever 64 makes  no operation, the driving gear 35 of the turning device will not be disengaged from  the driven gear 60. This secures constant turning operation.

IPC: B22D37/00
Filed: 1984-03-02
Abstract: PURPOSE:To adjust flow rate with high reliability by forming a magnetic flux by superconductive coils perpendicularly to a pouring nozzle having a throttling part and controlling the excitation current thereof. CONSTITUTION:A pouring nozzle 3 has the throttling part which increases the flow rate of a molten steel 1 and is disposed with superconductive coils 4a, 4b which form a magnetic flux in the direction perpendicular to the flow of the molten steel 1.
