In addition, both the total frictional load and the mold wobble are monitored by detecting their peak-to-peak values.

Abstract: An improved take-off device for a horizontal continuous-casting installation is provided. The arrangement comprises a frame and a mounting seated on rollers in the frame. The mounting is rotatable relative to the frame and supports the drive roll and its drive shaft, and a counter-pressure roll, which rolls preferably have counter-profiles corresponding to the cross section of the casting. The mounting comprises two concentrically arranged tubes which are sealed at their ends, thereby defining a cooling area therein. The adverse effects of gravity on casting quality may be mitigated by rotating the mounting relative to the frame, and locking it as a desired relative position, depending upon the cross-sectional configuration of the casting.

Abstract: To produce tubes of reactive metals, a melt (14) is removed from the annu gap (13) of a crucible (10). The temperature of the melt (14) is such as to ensure the formation of the solidus-liquidus zone (33) directly behind the annular gap (13), a planar solidification front (34) being created in a non supported region which is not exposed to the direct influence of a cooling means. In the subsequent region, the oriented solidification of the tube with high temperature gradients is realized, and the tube can be shaped or adjusted free of thermal influences. Only thereafter, the tube (25) is exposed to the action of cooling means (26, 31) to cool it without contact. In such a way, it is possible to produce tubes having a high stability and resistance to temperatures for use in turbines, heat exchangers or the like.

Abstract: A device for attaching an auxiliary fishing line to a primary fishing line, for use while trolling, with the primary fishing line connected to the ball of a downrigger assembly. The auxiliary line is slidably mounted on the primary line and the device is used to hold the auxiliary line on the primary line at a selected position. The auxiliary line remains separate from the primary line while trolling, enabling fishermen to fish with separate lines from a single rod while avoiding entanglement of the lines. When a fish strikes either line, the device slides to the end of the primary line, allowing both lines and the fish to be reeled completely in.

Abstract: A lifting platform is hinged via oscillating cranks forming a four rod linkage mechanism to a spacially fixed support frame at a continuous casting apparatus with a mold having a curved metal bar axis and disposed at the oscillating lifting platform and the lifting platform forms the connecting rod of this four rod linkage mechanism. In order to avoid the generation of cracks in the metal bar at the transition from the oscillating guide track for the metal bar to the spacially fixed guiding of the bar and in order to be able to adapt the oscillating cranks to close quarters, the longitudinal axes of the oscillating cranks intersect at a point while the mold is in middle position, which point is disposed on a straight line connecting the center of curvature of the guide track of the metal bar to the lower end of the oscillating support surface supporting the metal bar. The oscillating cranks are of differing lengths.

Abstract: Apparatus for agitating a fishing line and imparting to the lure an oscillating motion. The apparatus is mounted on the fishing pole and also releasibly engaged with the fishing line. In order to provide the motion a small electric motor causes a shaft to rotate. The shaft has helical threads and causes a rider slideably meshed with the threads to move forward and backward. The fishing line by reason of its attachment to the rider is agitated into an oscillatory motion which is transmitted to the lure.
